Full textAbstract:
This thesis presents a comparative study of two modern Muslim biographers of the Prophet of Islam, Muhammad Husayn Haykal and Sayyid Ja$ rm sp{c}$far Murtada, the one a Sunni the other a Shispc$ = i. In dealing with their works on the { it s = i ra}, the intention is to focus on some aspects of the life of the Prophet of Islam from the time when he resided in Makka. After outlining the authors' scholarly backgrounds, sources, methods, and purposes, etc., the thesis deals with certain specific issues concerning the Prophet's birth, his nursing and the reason behind the custom of having foster-mothers, the controversial stories of the splitting of his chest and of his participation in the sacrilegious war, his state both before and after the announcement to him of his Mission, the authors' interpretations of his night journey and ascent to heaven and lastly their discussion about the Prophet and miracles. This research should not be considered as historical in nature; rather, it aims at clarifying the similarities and differences which may be discovered between our two biographers, and at comparing their respective Sunn = i and Sh = i$spc$ = i approaches.

Full textAbstract:
La description se manifeste dans le roman zaynah sous deux formes essentielles : le portrait et le chronotope. La methode d'analyse est de caractere stylistique en ce sens qu'elle cherche a delimiter les faits linguistique specifiques au discours descriptif, a les classer et a envisager leur valeur stylistique ainsi que leur fonction par rpport a l'ensemble de l'oeuvre. Cette etude montre que la description peut etre identifiee sur les plans semantique, typographique et linguistique. Elle est denombrable et reflete le point de vue du descripteur. Elle met en oeuvre un langage specifique. Sa specificite apparait notamment dans l'usage du vocabulaire, du temps grammatical et des faits de styleThe novel zaynah provides two basic forms of description : characters portrayal and spatictemporal representation. The aims of our work, a stylistic attempt, is not only to classify and to define the scope of the linguistic features typical of the descriptive discourse - but to study their stylistic value and their functional role in the novel as a whole, as well. This work proves that while the descriptive mode can be identified at three levels: namely, semantics, typography, and linguistics, it is quantitatively listed, too. Generally, the descriptive discourse mirrors the viewpoint of the describer, creating a specific language which brings into play an original handling of vocabulary, tense, and stylistic figures

Full textAbstract:
This thesis, which is an analytical study and annotation of the book entitled Al-libyan Jima Yahill wa-Yahrum min al-Haywan by Ibn al-`Imad al-Aqfahsi, is divided into two parts. The first part contains a study of the book and its author, while the second part contains the Arabic edition of the book. They are divided into two volumes. The first volume consists of an introduction, four chapters and two appendices. The introduction of the thesis highlights the reasons for the selection of this particular research. indicating that this kind of research has not been undertaken before, as far as the researcher knows. Moreover, the importance of this research for Muslims is highlighted since it gives the relevant injunctions on various kinds of meat that they can eat. The research offers a summary of what some Muslim scholars have written on the science of zoology as they understand it. It also examines the masons for their writing on the subject and the main features of their treatises and studies. Following that, the researcher tries to ascertain the correct name of the book Al-Tibyan and the authenticity of its reference to the author. It is ascertained that the actual name of the book is Al- Tibyan fima Yahill wa-Yahrum min al-Haywan. Then the date for the composition of the book is discussed. The methodology of this edition follows. In the second chapter the researcher studies the author, trying to ascertain his name, date of birth, upbringing, attributes and ethics. The views of other people on the author and his writings are also presented. The third chapter deals with the political, social, and intellectual ethos. The fourth chapter comprises a study of the biographies of people mentioned in the manuscript. Them are two appendices at the end of the thesis: the first is a glossary of ambiguous words used in the manuscript and the second is a verification of the places mentioned in the manuscript and study. In order to facilitate the reader for cross reference to the Arabic manuscript, the researcher has indicated the relevant page/ line number, where necessary, (e.g. 000/00) in chapters four and appendice only. Finally the bibliography and indexes conclude the thesis.

L'apparition de la revue al hayat al masrahiyya (la vie theatrale) en 1977 repond a un bes0in urgent a un moment ou le theatre syrien cherchait sa voie entre attachement au patrimoine ancestral et la culture occidentale jugee un peu envahissante. Sous l'impulsion de son redacteur en chef, saad allah wannus et a son image, la revue se veut le creuset de la recherche et de la creation d'un theatre engage d'avant garde et authentiquement arabe. Mais rattachee au ministere de la culture, elle n'a pas toute independance de publication, ce qui conduit son redacteur en chef a demissionner, et la revue devient plus un catalogue d'articles theoriques, eloignes de la preoccupation essentielle du lectorat arabe.

The revue has been marqued by the strong personnality of its chief-editor saadallah wannus, then it looked for deep researches to create an engaged, authentic and "avant-garde" arabic theatre. Edited by ministry of culture in syria, the revue couldn't have all its independance. Therefore its chief-editor had resignd, and the revue had changed in simple catalogue of theoric articles very far from the essential preoccupation of arabic readers.

Zamzam, Mahmoud. "L'influence de la littérature française sur l'oeuvre de Mohammad Hussayn Haykal." Paris 3, 2002. http://www.theses.fr/2002PA030041.
Full textAbstract:
Dans cette thèse, l'accent est mis essentiellement sur l'influence de la pensée et de la littérature françaises sur l'art romanesque et l'esprit critique de l'écrivain égyptien Mohammad Hussayn Haykal, précurseur du roman arabe moderne au début du XXe siècle. En effet c'est grâce aux orientations de ses maîtres à penser que Haykal a passé plus de trois ans en France pour obtenir le doctorat en droit. Depuis, il s'adonne à la littérature et la pensée françaises (voir l'appendice). Ansi, Zaynab, son premier roman est le fruit de la lecture de Rousseau, Zola et Bourget. C'est un chef d'oeuvre qui reflète les tendances romantiques et naturalistes françaises. On trouve beaucoup de ressemblances à travers des comparaisons entre Zaynab et la Nouvelle Héloi͏̈se de Rousseau. L'interprétation des thèmes, et éléments des deux tendances réaliste et naturaliste franç̀aises est clairement identifiable dans chaque roman, conte ou nouvelle de Haykal. Aussi on a procédé à l'approfondissement de l'étude contrastive des oeuvres romanesques de Haykal et celles des écrivains français qui l'avaient profondément marqué : Rousseau, Flaubert, Anatole France, Taine, Zola etc. .In this thesis, the research has focused on the influence of the French literature and thought on the art of the novel and criticism of the Egyptian writer Mohammad Husayn Haykal. He has been to France where he spent more than three years to obtain a PHD in law. But Haykal showed complete interest in the French literature and culture. Zaynab, his first novel was obviously written under the auspices of French romanticism. It is the fruit of the reading of Rousseau, Bourget and Zola. It reflects the French romanticist and naturalist trends. Many resemblances and analogies have been thoroughly found through comparison between Zaynab and La nouvelle Héloi͏̈se of Rousseau as well as between Haykal's Waladi (my son) and Les confessions of Rousseau. Themes and elements of the French realism and naturalism are clearly identifiable in each novel, fiction and short stories of Haykal. Comparative studies are continously conducted everywhere in the research on the romanticist novel works of Haykal along with those of the French novelists who had clear impact on his art of narration and thinking : Rousseau, Flaubert, Anatole France, A. Comte, Taine and Zola. .

Full textAbstract:
Traditional stylistic classifications have not provided conclusive dates for the rock art of the Sahara, and the imagery can therefore not be placed securely in its cultural or environmental context. This thesis proposes a new methodology in which content and patina of the engravings are used to establish a chronological sequence, against the background of changing palaeoenvironmental conditions. This framework can then be used to explore aspects of the relationship between the rock art and the changing Holocene landscape. The engravings of the Wadi al‐Hayat, which were recently recorded by the Fezzan Rock Art Project, form the basis of this research. A total of 2466 images of animals were individually analysed and entered into a database. The depicted species are shown to reflect the local fauna, and their habitats coincide with the palaeoclimatic conditions of the central Sahara. Additionally, recent geomorphological analyses of the rock surfaces of the Messak provide a chronology for the patina, and show that the formation of each type of patina was dependent on environmental conditions. Through analyses of the animal engravings, categorised according to positively identifiable species and patina types, this thesis demonstrates a direct correlation between the content (i.e. species depicted) and patina of the engravings, and the palaeoenvironment. Both content and patina of the engravings indicate a development from wet savanna to dry savanna, and finally to desert conditions, consistent with the Holocene climatic sequence. This provides a chronological framework for the engravings and places them into a palaeoenvironmental context. The locations of the engravings of each patina group also correspond to the changing lake levels of the al‐Hayat palaeolake identified in previous palaeoenvironmental research projects, which in turn supports the chronology of the engravings. Through spatial analyses, the locations and landscapes preferred by the engravers for the creation of rock art can be identified, whilst the new chronological sequence allows us to explore changes in the cultural conventions that underlie the creation of the engravings. As well as providing a chronological framework and environmental context for the engravings for the Wadi al‐Hayat, the research presented in this thesis therefore has the potential to change our understanding of Saharan rock art.

This thesis is concerned with the relationships between landscape and antiquarian and natural history studies in the work of Hayman Rooke (1723-1806). Through a study of Rooke's work on natural history and meteorology, and ancient and Roman Britain, the processes through which antiquarian and natural historical knowledges were negotiated and legitimised are highlighted. This includes how landscapes were interpreted and understood - how antiquarian and natural historical practice functioned as a form of engagement with place.

Chronic kidney disease is associated with a high symptom burden that is strongly linked to poor individual outcomes and quality of life. The complex relationships among these symptoms remain poorly understood. This study was the first to identify symptom clusters from multidimensional perspectives in advanced chronic kidney disease. Adopting a symptom cluster approach has the potential to significantly advance symptom assessment and management. The symptom cluster model developed in this study has important clinical and heuristic implications, which can serve as a framework to encourage and guide new lines of intervention research to reduce symptom burden in this population.

Zala, Julianne. "Translating Anxiety in the Poetry of Maya Abu al-Hayyat." 2020. https://scholarworks.umass.edu/masters_theses_2/999.
Full textAbstract:
Maya Abu al-Hayyat (born 1980) is a Palestinian poet who thematizes motherhood, love, war/revolution, grief, and political hypocrisy in her poetry. In the context of Palestinian literature, she fits within a tradition of Resistance Literature, yet redefines it. Given that al-Hayyat has not been widely translated into English, this thesis presents 33 translations of her poems taken from her three poetry collections: Mā qālathu fīhī (Thus Spake the Beloved, 2007), Tilka al-ibtisāma-- dhālika al-qalb (This Smile, That Heart, 2012), and Fasātīn baytīyya wa ḥurūb (House Dresses and Wars, 2016). Throughout these three collections the poet shifts her use of vocalization and her poetic techniques. As argued throughout, translating al-Hayyat into English is important because it marks a shift from resistance as a uniform, collective experience to an individual and multifaceted one.
Additionally, in this thesis I argue that the speakers in al-Hayyat's poetry are anxious agents. I interpret the speakers’ anxiety as manifested in the body and caused in part by living under occupation. The speakers are agents because they criticize patriotic motherhood and gender-based inequality. Finally, I explain how the translation concepts of renarration and the deformation zone inform each other because they force the translator confront their position in society and to the text. These terms are significant because they address the anxiety of translators potentially enacting orientalist violence and catering to American poetry values when translating Arabic women's poetry into English.

Cinnamomum kanehirae Hayata is an endemic species to Taiwan. It is a large evergreen tree. Hermaphrodite flowers are produced from January to March, and drupe mature during September to October. Inflorescence primordia occur in Mid-December. Anther primordia appear by late December. Anthers are 4-celled and open by uplifting valves. The anther walls of valves are five (to six) layers consisting of an epidermis, an endothecium, two (to three) middle layers, and a tapetum. The tapetum is of amoeboid type. Tapetal cells have up to four nuclei. Microspore mother cells undergo meiosis through successive cytokinesis from mid to late January and give rise to tetrads of microspores, which are mostly isobilaterally arranged and seldom tetrahedrally or in “T” shap. Anthers are dehiscent in early February. Mature pollen grains are 2-celled in early February, and they are spheroidal and inaperturate. Carpel primordia appear in early January. Ovule primordia appear in mid- January. Ovules are anatropous, bitegmic, crassinucellate and with 2~5 cell-layered nucellar cap while embryo sac is mature. From mid to late January, the outer integument is of 3~5 layers of cells in thickness, while the inner integument is composed of 2~3 layers of cells. The micropyle is formed by inner integument. A megaspore mother cell undergoes meiosis, resulting in a linear tetrad of megaspores. The megaspore at chalazal end is functional. The development of embryo sac is of the Polygonum type. Three antipodal cells degenerate soon before fertilization. Developing endosperm is of the nucellar type. The embryogeny is of the Onagrad type. Mature seed exalbumious; cotyledons straight, auricled and massive.

Abstract The aims of this study were to investigate the antioxidant effect, inhibition of copper-mediated LDL oxidation, anti-inflammatory activity of pine (P. morrisonicola Hay.) needles and to analyze its polyphenol contents. Pine needles were extracted with four solvents (hexane, ethyl acetate, methanol and water). Results showed that ethyl acetate extracts of pine needles (NEE) had good antioxidant activity in DPPH radical scavenging capacity (IC50= 80 μg/mL), TEAC and ORAC values (500 μg/mL NEE equivalent 357 and 25.7 μM Trolox, respectively). Scavenging effects of NEE on super-oxide anion and nitric oxide radical were 60% and 25%, respectively, at a concentration of 500 μg/mL. In the Cu2+/LDL oxidative modification system, NEE significantly retarded LDL oxidation through prolonging the lag phase of conjugated diene formation, decreasing the amounts of lipid peroxidation products (TBARS) and slowing the relative electrophoretic mobility (REM) of LDL. In addition, NEE significiently inhibited RAW 264.7 murine macrophages uptaking ox-LDL. As to antioxidant contents of various pine extracts, NEE has the high amounts of polyphenol (123 mg/g) and flavonoids (64 mg/g) content. A HPLC method was used to indentify and quantify the polyphenol contents in NEE, the results showed that NEE contained epicatechin (EC) and p-coumaric acid. Thus, NEE showed higher antioxidant activity than other solvents extracts might be attributed to its abundant polyphenol contents. Nitric oxide (NO) production had been implicated in the process of carcinogenesis and inflammation. In this study, RAW 264.7 macrophage cells were treated with LPS to simulate the inflammatory model in vitro. The results showed that both NO and ROS were decreased after treating with NEE at the concentration of 75 μg/mL. NEE inhibited the protein and mRNA expression of COX-2, iNOS and IL-1in RAW 264.7 macrophagesIt is suggested that the anti-inflammatory activity of NEE was at least, partly due to their inhitory effects on the activation of iNOS, COX-2 and IL-1. In conclusion, NEE could attenuate the oxidative stress by scavenging free radicals; reduce excessive iNOS and COX-2 expression in macrophages and lipoprotein oxidation in vitro.

Rhododendron rubropilosum Hayata var. taiwanalpinum, one of the endemic Rhododendron species, distributes in high mountain area of Taiwan. According to the literature review, little information on genetic structure and its relationship with climate changes was reported. In this study, the genetic structure of R. rubropilosum taiwanalpinum in relation to climate changes was examined based on microsatellite loci. The result indicated that the isolated eight microsatellite loci were significantly deviated from Hardy–Weinberg expectations due to the heterozygote deficiency which showed the loss of genetic polymorphisms. The FST of R. rubropilosum taiwanalpinum was 0.0532 on average, showing lower differentiation. The analysis of the relationship between genetic diversity and population size revealed that the vulnerability of population was correlated to the population size and low diversity in the higher altitude of this area. The findings suggested that the genetic diversity of R. rubropilosum taiwanalpinum was positively correlated to population size as affected by temperature, and also correlated to the altitude of its distribution. Rhododendron pseudochrysanthum Hayata, a dominant vegetation, is almost lacking of understory species along the trail of East Peak of Mt. Hohuan. Based on our observation, we thus hypothesized that the unique phenomenon might be due to the allelopathy. To test the hypothesis, bioassays of the 1% to 5% aqueous extracts of leaves of R. pseudochrysanthum showed significant inhibition on radicle growth of Brassica chinensis, Lactuca sativa, Amaranthus gangeticus and Bidens pilosa. Because plant residues of the Rhododendron may release allelopathic compounds to suppress the growth of understory species during the decomposing plant residues in soil, we thus conducted a serious of experiment by using 50 g leaves soaked in 950 ml distilled water and allowed the leaves to be decomposed in different time intervals, 1, 2, 4, 8 weeks. The aqueous extracts were obtained at the elapsed intervals of decomposition, and were bioassayed. The bioassay results of the aqueous extracts showed significant inhibition on radicle growth of B. chinensis, L. sativa, A. gangeticus and B. pilosa. We also found the most inhibition was shown in the first and second aqueous extracts, but the phytotoxicity decreased in the subsequent extracts. Furthermore, phytotoxic phenolic acids, such as o-hydroxyphenylacetic, vanillic acid, p-coumaric acid, syringic acid, p-hydroxybenzoic acid, 3,4,5-trimethoxybenzoic acid, veratric acid, gentisic acid, protocatechuic acid, ferulic acid, o-coumaric acid and caffeic acid were tentatively identified as compared with authentic compounds by means of paper chromatography. The amount of these compounds was decreasing with time interval of decomposition, indicating that the phytotoxicity decrease was correlated to the amount of phytotoxic phenolics present in the extracts. Regardless of the adaptation of Rhododendron plants to the climate and environment, the existence of allelochemicals might be responsible for the exclusion of plant species underneath Rhododendron stands, resulting in the low plant diversity of understory species.

This article is divided into three sections: the shoot development , fruit ecology and development, and preliminary breeding of the devil tanoak (Lithocarpus lepidocrpus (Hayata) Hayata). The first section is the development of the devil tanoak shoot. Devil tanoak of high altitude observation point is distributed about an altitude of 1500 meters and located at road sides of Lixing industrial road in Nantou County, with the total count of 15 observation trees. Devail tanoak of low altitude observation point is growing at about an altitude of 70 meters in Wufeng, Taichung, and total observation trees are five 7-9 year old trees. The sprouting period of the devil tanoak is usually in March to April. After the shoots are mature, inflorescence and anthesis form a number of top buds appears in August to September. Therefore, the devil tanoak of high altitude grows vegetative shoots and inflorescence one time in a year. The devil tanoak of low altitude is sprouting in March and July. Each shoots is almost inflorescence after mature. May and October are more obvious flowering and the fruit also mature at December to next year’s January and next year''s September. The second section is the fruit ecology and development of devil tanoak. The devil tanoak of high altitude usually completely finishes anthesis in October. And pistillate flower will be little fruit stage to pass winter and into the period of fruit stagnation. Until next year''s new shoots inflorescence, the fruit will significantly grow. The devil tanoak of low altitude has two anthesis period. Spring fruit is the fruit from the shoot first sprouted in March and finished anthesis, and the curve of growth from fruit diameter, height, weight are fitted S curve. The fruit will be mature in December to next year’s January and natural drop from shoots. Autumn fruit is the fruit from the second sprouted in July. The curve of growth from fruit diameter, height, weight is fitted double S curve. Autumn fruit should start growing until next year''s Spring flower anthesis, and the fruit will be began to be mature in October. Therefore, the fruit from Spring or Autumn flower grow in significant difference. The third section is the survey of calibration tanoak fruits and seed traits and preliminary breeding. The experiment method is picking up 30 to 40 fruits per plant, and removing the bad fruit, for example, bitten by pests, and then randomly selected 20 fruits per plant. Record the fruit and seed traits. Due to the cupule of natural drop fruit integrity are greatly diverse, so we removed the cupule of fruit and measured the content which only contains shell''s nut weight, nut height, nut diameter, and the edible seed weight without shell. After analysis, we found seed weight is significantly correlated with nut weight, nut height, and nut diameter. And we will found nut weight is the most important factor. Also, high edible rate is an important factor that we need. Therefore, we can also perform preliminary breeding based on the tree''s trait of nutweigt:seedweight''s ratio. Among the selection of the current investigated plants, LC201 and LC197 both shows high rate and high edible weight, and thus could be the best strains.

The noncoding region sequence of cpDNA and the allozyme marker were used to conduct the phylogeographical study of Castanopsis carlesii, a subtropical and temperate tree species in Taiwan. C. carlesii, belonging to the Fagaceae, is one of the most common and dominant tree species which adapt to the subtropical and tempetate climate in Taiwan. In this study, we examined spatial patterns of chloroplast DNA (cpDNA) variation in a total of 30 populations of C. carlesii, including 201 individuals sampled throughout Taiwan. By sequencing two cpDNA fragments using universal primers (the trnL intron and the trnV-trnM intergenic spacer), we found a total of 1663 bp and 21 polymorphic sites. These gave rise to a total of 28 cpDNA haplotypes. The level of differentiation among the populations studied was relatively high (GST = 0.723). Two ancestral haplotypes are widely distributed. The Central Mountain Ridge (CMR) of Taiwan represents an insurmountable barrier to the east-west gene flow of C. carlesii. Among the populations studied, three separated populations, at Lienhuachih, Fushan and Lichia, have high nucleotide diversity. Estimates of NST - GST for populations on both sides of the CMR indicate that no phylogeographical structure exists. According to the genealogical tree, number of rare haplotype and population genetic divergence, this study suggests that two potential refugia existed during the last glaciation: the first refugium was located in a region to the north of Hsuehshan Range (HR) and west of the CMR; the second refugium was located in south, especially southeastern Taiwan. In fact, the second refugium happens to be the same as that reported for Cyclobalanopsis glauca. A “Star-like” genealogy is characteristic when all haplotypes rapidly coalesce and is a general outcome of population expansion. The neutrality test and mismatch distribution also suggest demographic expansion. Using genetic parameters to determine the heterozygosity and the mean FST value of each population, we inferred the evolutionary history of Castanopsis carlesii in Taiwan. In this study, 22 populations of C. carlesii throughout the island were sampled covering an elevational range of 50~2300 m. Starch gel electrophoresis was used to assay allozyme variations, and 11 loci from nine enzyme systems were detected. Average values of genetic parameters describing the within-population variation, the average number of alleles per locus (A = 2.5), the effective number of alleles per locus (Ae = 1.38), the allelic richness (Ar = 2.38), the percentage of polymorphic loci (P = 69%), and the expected heterozygosity (He = 0.270) were estimated. High levels of genetic diversity were found for C. carlesii compared with other local plant species. From the data of expected heterozygosity, one major diversity center was situated in central Taiwan corroborating previous reports for other plant species. According to the mean FST value of each population against the remaining populations, the most-divergent populations were situated in two places. One includes the populations of Anmashan, Fushan, and Tungao, and is located in north-central Taiwan between 24.80°N and 24.20°N. The other is located in southeastern Taiwan between 22.40°N and 23.10°N, and includes the populations of Hsinkangshan, Tona, and Tawu. These two regions are approximately convergent with the most divergent locations determined for several other plant species using chloroplastic DNA markers. In conclusion, the result of genetic differentiation study obtained from isozymes agrees well with that from chloroplastic DNA markers.

The aim of this study was to obtain the molecular marker of Taiwania cryptomerioides Hayata based on DNA sequence data of PCR- sequencing and inter-simple sequence repeat (ISSR), and to evaluate the genetic diversity of populations of Taiwania cryptomerioides Hayata and molecular phylogeny of T. cryptomerioides and Taiwania flousiana Gaussen. The sequence data based on the internal transcribed spacer (ITS) of a total of 108 samples of T. cryptomerioides were determined. Eight different populations of T. cryptomerioides and 12 samples of T. flousiana from Yunnan, China were analyzed. The finding of the study showed that heterogeneity of ITS region within individuals of T. cryptomerioides was high by showing high nucleotide diversity among ITS sequences both in T. cryptomerioides ( π = 0.18153) and T. flousiana ( π = 0.19751). The findings fit in Tajima’s D test of neutrality based on DNA sequence variation in the ITS region of T. cryptomerioides and T. flousiana. It is not obvious to incorporate into different population through clustering analysis based on data of the ITS region of T. cryptomerioides and T. flousiana. However, slightly genetic differentiation between T. cryptomerioides and T. flousiana was found, which figured of Fst (Fst = 0.0441~ 0.0856, an average value = 0.0611). On the other hand, the samples were studied by using ISSR markers. Of the 100 primers screened, 4 produced highly reproducible ISSR bands, and 24 discernible DNA fragments were generated with 17 being polymorphic. Based on cluster analysis of molecular data, the cluster is not clear among populations of T. cryptomerioides and T. flousiana. The analysis of AMOVA revealed that the variance component between species of T. cryptomerioides and T. flousiana was 38.54％ (P < 0.001); however, the variance component within species is 61.46 (P < 0.001). The variation within population of T. cryptomerioides was 84.74％ (P < 0.001) and the variance between populations is 15.26％ (P < 0.001), indicating that the genetic diversity of individuals within population was high. The aforementioned data suggest that gene flow among different populations of T. cryptomerioides was high, indicating that the genetic diversity was high among individuals of T. cryptomerioides but was low between populations. Furthermore, it is concluded both species are genetically closer and could be grouped into the same species.

Angiosperms exhibit great diversity of sexual systems, as the majority of extant species are hermaphrodite, the evolution of unisexuality has drawn attention since Darwin’s age. The reproductive biology of Daphne arisanensis Hayata (Thymelaeaceae), an endemic shrub in Taiwan, had rarely been studied before. Field observations implied that populations of D. arisanensis comprise morphologically bisexual and male-sterile individuals, hence this species may be gynodioecious. However, no unequivocal evidence had been presented yet. To clarify the true sexual system of D. arisanensis, I investigated the spatial and temporal expression of sexuality, and tested the reproductive potential of each floral morph. In this study, phenology surveys were conducted in Meifeng, Yuanfeng, Hehuanshan, Dayuling and Guanyuan during 2014-2017. Pollination experiments were operated in Guanyuan and the Hehuanshan-nearby alpine populations respectively. No individual altered the flowering type in this three-year observation. Male-sterile flowers had the ability to set fruits either with pollination or without fertilization (i.e. apomixis). The gynoecia of morphologically bisexual flowers displayed receptivity to pollens from either itself or other plants, but they hardly set fruits among all pollination treatments. In addition, unusual flowers with different degrees of male-sterility were occasionally found on morphologically bisexual plants. The extremes were quite similar to the typical “female” flowers in male-sterile plants and indeed set fruit under open pollination. The seeds from all kinds of treatments showed germination potential. Great variations in morph ratio, floral traits and floral phenology were found among populations. Compared to the Guanyuan population, individuals in alpine areas showed larger flower size, longer floral lifespan and lower fruit-set rates under both open pollination and apomixis. Various nonspecific nocturnal moths were observed pollinating in both of the populations. To provide materials for inferring the possible evolutionary scenario of the gender divergence in D. arisanensis, I also conducted bagging experiments to another congeneric hermaphroditic species, D. kiusiana Miq. var. atrocaulis (Rehder) Maekawa, in Yangmingshan. The results show that 49% of the bagged flowers had set fruits via autonomous selfing, suggesting that self-pollination may be common in genus Daphne. These findings indicate that the sexual system of D. arisanensis is cryptic and leaky dioecy. The flowering phenology and floral traits varied among populations, and the evolution toward dioecism would probably be correlated with the self-pollination pressure in genus Daphne.

Full textAbstract:
Tese de mestrado, História e Filosofia das Ciências, Universidade de Lisboa, Faculdade de Ciências, 2019A descoberta de um conjunto de teorias astronómicas associadas à tradição hay’a tem provocado uma polémica em História das Ciências durante os últimos 60 anos. Tratando-se de uma forma de astronomia medieval árabe, semelhante à que Copérnico propôs cerca de 150 anos mais tarde, a sua descoberta implicou a revisão de algumas teorias geralmente aceites. Se, por um lado, se evidenciou uma tradição árabe cujos modelos e mecanismos se distinguiam dos ptolemaicos, por outro, iniciou-se uma discussão sobre a influência que esta tradição teria tido na astronomia europeia. Considerando a relevância atribuída ao astrónomo polaco em narrativas sobre o início da ciência moderna, a polémica tem sido abordada por historiadores de ciências matemáticas, árabes e ocidentais. Partindo das interpretações propostas por alguns destes, assim como de determinadas fontes associadas ao problema, o principal objectivo desta dissertação é desenvolver uma visão crítica acerca da polémica historiográfica. Propõem-se, nesse sentido, dois capítulos: um primeiro, relacionado com a revisão de conceitos centrais, assim como da hipótese de circulação de conhecimento na Europa renascentista; e um segundo, relacionado com uma análise da própria polémica, ou seja, com a procura de entender o que foi a tradição hay’a, de que forma esta se assemelha à astronomia coperniciana e quais as possibilidades de transmissão ou descoberta independente. Investigando também narrativas sobre o início da ciência moderna, contrastaram-se três abordagens diferentes: uma fundamentalmente matemática, preocupada com a comparação técnica das teorias astronómicas; outra que, baseada na comparação das próprias tradições de astronomia, propõe uma reflexão sobre a possibilidade de transmissão; e uma última que, na ausência de uma prova de transmissão, tem dispensado uma consideração aprofundada sobre a polémica. Concluiu-se, finalmente, que existe uma falta de diálogo principalmente entre a segunda e a terceira abordagem, na medida em que, em algumas das narrativas recentes sobre Copérnico, a “revolução científica”, ou o início da ciência moderna, parecem conhecer a tradição hay’a apenas parcialmente.
The discovery of several astronomical theories related to the hay’a tradition has been motive for a controversy in History of Science for the last 60 years. Being an Arabic medieval astronomy form, similar to the one Copernicus proposed about 150 years later, its discovery implied the revision of some generally accepted theories. If, on the one hand, it was clear that there was an Arabic tradition that proposed models and mechanisms different from the Ptolemaic ones, on the other hand, it launched a discussion concerning the influence this tradition might have had in European astronomy. Considering the importance given to Copernicus by narratives relating to the beginning of modern science, the controversy has been approached by historians of mathematics, Arabic and Occidental science. Taking into account the interpretations proposed by some of those historians, as well as some of the texts related to the historiographical problem, the main purpose of this dissertation is to develop a critical view concerning the controversy. In order to achieve this, two chapters were proposed: a first chapter, related to the revision of the central concepts, as well as the idea of knowledge in circulation in Renaissance Europe; and a second, about the controversy itself – that is, the understanding of hay’a tradition, the ways in which it resembles Copernican astronomy; and the possibilities of both knowledge transmission and independent discovery. By also looking into interpretations in narratives concerning the beginning of modern science, it was possible to distinguish three different approaches: one essentially mathematical, mainly focused on the technical comparison of the astronomical models; another which, based on the comparison of the astronomical traditions in question, proposes a reflection about the possibility of knowledge transmission; and a third that, supported by the absence of a definitive proof, dismisses a significant consideration about the controversy. It was concluded that there was a lack of dialogue, especially between the two latter approaches, in the sense that some of the narratives concerning Copernicus, the scientific revolution or the beginning of modern science seem to take hay’a tradition in consideration only partially.

Abstract： Superoxide dismutase（SOD），a family of metallo-enzymes, catalyze the dismutation of harmful superoxide free radical（O2·-）to molecular oxygen and hydrogen peroxide（H2O2）, and is considered a major enzymatic defense against O2·-. SOD could be classified into three types according to their metal cofactor：CuZnSOD, MnSOD, and FeSOD. The biological activities of the plant, Anoectochilus formosanus in the use of cardiovascular disease and hepatitis may be related to the antioxidants which have never been reported from A. formosanus. In this study, the SOD activity was assayed by combining polyacrylamide gel electrophoresis and densitometry. It was found that the optimal SOD activity of the plant was pH 6.8-7.2 and optimal temperature at 40 °C. Total antioxidant activity（TAA）was determined by HRP＊/ ABST＊ / H2O2 method, and it was found 146.5-176.9 mg ascorbic acid / fresh weight in the plant. In general, the SOD activity and TAA of old leaves of the plant were reduced as compared with young leaves（10﹪for the SOD activity and 15﹪for the TAA）. Based on the sensitivity to H2O2 and KCN, 1 MnSOD and 1-4 CuZnSODs were identified in various plant strains. Therefore, SOD patterns could be used as markers and provide a rapid and easy tool for identification of A. formosanus strains. On the other hand, CuZnSODI was found to be a fast move rate enzyme which has never been found in other plants in our laboratory before. It is considered suitable for purification and determination of amino acid sequence and was purified by ammonium sulfate fractionation, DEAE＊anion-exchange chromatography and FPLC＊ gel-filtration chromatography. The molecular weight of CuZnSODI was found approximately 20.1 KDa as indicated by SDS-PAGE＊ and silver staining. The N-terminal amino acid sequence analysis of CuZnSODI gave 3KAVAVLKGNS12 and identical with the CuZnSOD in Lycopersicon esculentum, Medicago sativa and Marchantia paleacea. ＊ HRP: horseradish peroxidase; ABTS: [2, 2''-azino-bis（3-ethylbenzothiazoline-6-sulphonic acid）]; DEAE: diethylaminoethyl; FPLC: fast performance liquid chromatography; SDS-PAGE: sodium dodecyl sulfate-polyacrylamide gel electrophoresis.

Summary Machilus japonica var. kusanoi is an endemic species to Taiwan﹒ The large evergreen trees are monoecious﹒Bisexual flowers are produced from January to March﹒ Fruit maturing June to July﹒ Inflorescence primordia are emerged from the apical meristem in early- January. Anther primordia are composed of the protoderm and the central cell mass in mid- January. The protoderm will differentiate into the epidermis later. As pollen mother cells are formed, the wall layer is consisting of, from inner to ourter, a tapetum cells, two middle layers, an endothecium, and the epidermis. Isobilateral tetrads of microspores are mostly formed by successive cytokinesis. Mature pollen grains are 30~45μm ×30~45μ in size, 2-celled. Anther dehiscening with valves. Ovule primordia are formed on the enrolled carpel margins in mid- January. The megaspore mother cell is located at the 5rd to 7th layer of cells in the nucellus. It divides transversally to form a linear megaspore tetrad, and the functioning megaspore at chalazal end. The embryo sac is monosporic and follows to the 8-nucleate Polygonum type. The egg cell and two synergids are located at the micropylar pole of the embryo sac. Two polar nuclei fuse before fertilization. Three antipodal cells are ephemeral. The endosperm consists of free nuclei during development. The embryogeny is identified to the Asterad type. Each seed contains 2 massive cotyledons.

The tankan accessions witch selected by fruit size and brix scale were collected from Hsinchu, Taichung and Nantou. For further analysis, they were grafted on ‘sunki’ mandarin and planted at Horticultural Station. The objective of this study was to identify the genetic variance among the tankan accessions and the genetic relationships among tankan and other citrus. The unstability fruit characters of several accessions suggusted that they might still be in juvenile phase. Therefore, only vegetative characters and RAPD markers were employed in the analysis. The vegetative characters investigated included shoot length, node number, leaf length, leaf width, leaf length/leaf width, wing length, wing width, wing length/wing width, leaf length/wing length, leaf thickness, leaf margin length, margin serration number, margin serration number/cm, oil gland number/cm, oil gland number/cm2, and leaf area. Through cluster analysis of these 16 characters, the tankan accessions diverted into two main groups, big and small fruit group respectively. Within each group, the accessions displayed diversity as well. The grouping patterns of the accessions showed no relevance to geographical origin. The ordination pattern of the principal component analysis was similar to the grouping pattern of the cluster analysis, and the first three principal components derived from the principal component analysis explained 76.28% of the observed variation. According to principal component analysis, leaf length/leaf width, wing length, margin serration number/cm, oil gland number/cm and oil gland number/cm2 were the major discriminating traits. The dendrogram generated by cluster analysis based on the 5 major discriminating traits was resemblance to that based on 16 vegetative characters. Therefore, our result indicated that the 5 major discriminating traits could be useful for tankan genetic variance analysis and for early selection of fruit size. 293 10-mer random primers were screened in the RAPD analysis, 28 of which produced no amplification, and 250 of which amplified monomorphic products, and 15 of which produced polymorphism. The monomorphic bands produced by the 15 primers were reproducible; however, the polymorphic bands were not reproducible. The 265 primers generated total 1517 reproducible monomorphic bands revealed high genetic similarity among the tankan accessions. The non-reproducibility of the polymorphic bands might suggest the complexity of the genetic nature of tankan. Whereas, the PCR condition caused these perplexed result could not be ruled out. Principal component analysis of 16 vegetative characters was also carried out to establish the relationship of tankan and other citrus. The first three principal components accounted for 84.69% of the total variance. The ordination of tankan and other citrus after principal component analysis was similar to the grouping patterns generated by cluster analysis. Mandarins and tankan were clustered in a group, and sweet oranges, grapefruits and minneola tangelo were clustered in another. 19 chosen primers from 250 primers screened in the previous work produced 189 stable bands. Among the 189 bands, 153 were polymorphic. The dendrogram generated by cluster analysis based on 153 polymorphic bands was resemblance to that based on 16 vegetative characters. These results indicated that tankan was closer to mandarins than to sweet oranges, grapefruits and minneola tangelo and didn’t support that tankan is one of the subsection Sinensioides. Besides, the highly similarity among haili and tankan supported the possibility that haili may derived from tankan.

Many literatures reported that phenolic compounds is known to exhibit antioxidant and antithrombogenic effects and reduce the risk of cardiovascular diseases. Key point of the development of cardiovascular disease is according to vascular smooth muscle cell proliferation. The present study was to investigate the regulation of blood pressure by Pinus morrisonicola Hayata. Primarily, test samples were prepared by extraction in water, ethanol and ethyl acetate solvents or fermented by various sample/sugar ratio during 12 weeks periods. Determination of antioxidant activity, including reducing power, DPPH radical scavenging activity and ABTS+ radical cation scavenging assays were conducted. Furthermore, total phenolic contents, flavonoid content and condensed tannins content were investigated. The results demonstrated that different treatment of DPPH radical scavenging capacity was between in 60-80%, ABTS+ radical cation scavenging rate was about 60% and reducing power reached up to 0.85 times of BHA equivalent. It showed good efficacy of inhibitory rate. The condensed tannins content suggest a time-dependent relationship. Total phenolic content of Pinus morrisonicola Hayata is 500-800 μg GAE / ml at 12th week. And flavonoids contents is 10-18 μg quercetin /ml at 12th week fermentation. The phenolic compounds and flavonoids in extracts are higher than those in ferments. Both of extraction and fermentation, illustrated that active ingredients analyzed by HPLC, abietic acid and β-sitosterol, are 91-243 ppm and 66-760 ppm observed respectively. Conclusively, our data showed the optimal fermentation period was three to four weeks. The concentration and antioxidant capacity of sample extract was positively correlated. Both extracts and ferments of Pinus morrisonicola Hayata could inhibit smooth muscle cell growth about 20-30%, and can effectively extend the activated partial thromboplastin time (APTT) more than 30 seconds, showing anticoagulant activity. Obviously, the development of health drink from Pinus morrisonicola Hayata is expected in the near future.

The goal of this experiment is to investigate the most suitable harvest maturity, increase storability and discuss the possibility of delaying harvest and the influence of different pre- and post -harvest processing method to the tankan quality and storability. Increase fruit appearance and fruit storage quality to create higher output value. The fruit of different harvest date, with the harvest maturity increase, the peel L value lower, the peel getting darker. The peel color a value rise, peel color from green to red with the harvest date delay. With the harvest maturity increase, the peel b value decrease, peel color from yellow to orange. The excessively late harvest one can increase the fruit peel thickness; the TSS and TSS/TA can increase, but titrate acid getting lower. Fruit after harvest which spray by 3% calcium chloride and dips in 53 ℃ hot water for 3 minutes, then separate stores it at 5 ℃ and 15 ℃, the 15 ℃ group have highest decay rates. 12 weeks later, both heat treatment and calcium chloride processing group are completely rotten. But after 12 weeks, 5 ℃ group’s heat treatment have lowest decay rate, the calcium chloride is next, untreated fruit have highest decay rate. There’s no difference in weight loss rate, the peel color, fruit pulp degree of hardness and the fruit juice percentage when stores in 15 ℃ no matter what treatment have been done. But fruit of every treatment after storage in 5 and 15 ℃, the TSS and TSS/TA are both getting higher with the time pass, but the TA is going opposite way. Compare 1.5 and 3% pre-harvest calcium chloride treatment,1.5% treatment group has brightest peel color and highest fruit juice percentage. All three treatment have no affect in fruit size, peel thickness, the TSS, TA, and TSS/TA. No matter when doing the pre-harvest bagging, always have higher peel color L, a and b value then unbagging fruit. It means bagging fruit are brighter and more orange. Early bagging can raise fresh weight, but late bagging shows otherwise. The juice percentage between different bags are between 45.6-50.5％, no specific difference between them. The peel thickness is higher after bagging compare to control group, there’s obvious differences. Generally bagging will lower the TSS of the fruit, the earlier the TA lower, and earlier the TSS/TA higher.

Miyazaki Hayao, is most Taiwan children’s collective memory in 1980. His unique storytelling and quiet but far-reaching Miyazaki’s style lead us to grow with the role together. And his constructed film world is not only the memory of audience but also the director’s memory. For the director's creative intent has been discussed in the literature, but for the image he created wasn’t often been discussed. This study will try to proceed from Miyazaki Hayao's life and then go to the his works, the use of textual analysis and hermeneutics to understand the world view of these works, and try to analyze the style of his works and study of cultural meaning by researcher’s view.

Hypericum nagasawae Hayata and H. nokoense Ohwi are both endemic species in Taiwan. It is difficult to determine these two species since the closely morphological similarity between them. In this study, 4 chloroplast DNA non-coding regions, accD – psaI intergenic spacer, trnE – trnT IGS, rpl16 intron, and trnV – trnM (trnV intron included) IGS, were used to analyze their relationship. The results of molecular analysis are consistent with the taxonomic treatment of Robson (1996). Geographically, H. nagasawae is widely distributed in mountainous regions above 2,300 m in Taiwan, while H. nokoense is restrictively distributed in limestone regions in Shiu-Lin Township, Hualien. In order to uncover the population genetic structure of H. nagasawae, a total of 150 samples were collected from 10 populations, and two chloroplast DNA intergenic spacers, accD – psaI and trnE – trnT, were analyzed. 10 haplotypes were detected with 4 main haplotypes limitedly distributed in specific regions. Genetic differentiation among populations was generally high (mean FST = 0.744, Nm = 0.09). Both haplotypes in Mt Peitawu are endemic with the farthest genetic distance from other haplotypes. It suggested that the populations between Mt Peitawu and other regions have a long-term geographical isolation. The genetical distance and geographical distance (Isolation by distance test) have a moderate positive correlation when the population of Mt Peitawu was excluded. According to the result of Nested Clade Analysis, past fragmentation followed by range expansion had occurred. By integrating the present result and previous studies for other alpine plants, Northern Central Ridge was the genetic diversity center of alpine herbs of Taiwan. Glaciation might have played an important role contributed to the distribution pattern of haplotypes. According to neutral theory test (Tajima’s D, Fu & Li’s test) and BEAST software, however, last Glacial Age did not significantly influence population size.

This research focuses on lignans from Taiwanese medicinal herb Schisandra arisanensis Hayata. Their CH2Cl2 and MeOH extracts were investigated by using chromatography and twenty lignans were isolated. In the course of our study on lignans of S. arisanensis, five new compounds, arisanschinin A (1), arisanschinin B (2), arisanschinin C (3), arisanschinin D (4), arisanschinin E (5) together with fifteen known compounds, binankasurin A (6), kadsurarin (7), schisantherin B (8), schisantherin A (9), meso-dihydroguaiaretic acid (10), kadsumarin (11), kadsulignan K (12), kadsulignan D (13), kadsurin (14), angeloyl-binankadsurin A (15), acetyl-binankadsurarin A (16), schizanrin F (17), schisantherin D (18), kadsuphilol A (19) and kadsuphilol C (20) were isolated by using liquid chromatography. The new compounds 1-4 possess a C18 dibenzocyclooctadiene skeleton and compound 5 has an open ring system, biphenyldimethylbutane. All the structures of above compounds were elucidated by 1D, 2D-NMR spectroscopic analysis and physical methods including IR, mass, UV, optical rotation and NMR, and also by comparisions with the published data. The absolute stereochemistry of compounds 1-5 was determined by circular dichroism and NOESY. According to the spectra of CD, the configuration of compounds 1-2 were R form and compounds 3-4 were S form. The radical-scavenging activity of these compounds were tested and evaluated by reation with DPPH (1, 1-diphenyl-2- picryhydrazyl) free radical.

In previous studies, some phytochemicals isolated from species of Eurya, a member of Theaceae family, showed various bioactivities. For example, chrysoeriol from methanolic extract of leaves of Eurya ciliata stimulated proliferation and differentiation of osteoblastic MC3T3-E1 cells. E. emarginata is also used as a traditional folk medicine in Korea to treat ulcers and diuretic. E. glaberrima Hayata is one of the endemic species distributed in broad-leaved and mixed forest at elevations between 1500 to 3300 m above sea level in Taiwan. In order to clarify the medical and ecological roles of E. glaberrima, the natural products of E. glaberrima with anti-hepatocarcinoma cell, allelopathic activity were investigated. In this study, we used the methanolic extract of twigs and leaves of E. glaberrima to test the cytotoxicity and isolated natural compounds. On the other hand, we used the aqueous extract of E. glaberrima leaves to test the allelopathic potential. Five known compounds, namely, rengyolone (1), betulinic acid (2), taxifolin 3‒O‒β‒D‒xylopyranoside (3), quercitrin (4) and hyperin (5), were isolated from methanolic extract of E. glaberrima and one acetylated product 3-O-acetyl betulinic (2a) were identified by NMR and ESI-MS-MS data analyses. Rengylone revealed 50 % inhibitory effect at 40 μg/ml on HepG2 2.2.15. 3-O-acetyl betulinic had better cytotoxic effect than betulinic acid. All of them didn’t show the anti-HBV effect. In addition, in order to test the allelopathic potential of E. glaberrima, the aqueous extracts (1~5%) of leaves of E. glaberrima were bioassayed by using six tested plants, namely, Brassica chinensis, Lactuca sativa, Setaria italica, Ocimum basilicum, Cucumis sativus and Bidens pilosa. The results exhibited that the aqueous extracts of E. glaberrima could inhibit the radicle growth but not seed germination of the six tested plants. The leachate of E. glaberrima leaves could significantly inhibit the radicle elongation of B. chinensis and S. italica. In our study, betulinic acid and hyperin didn’t show the allelopathic effect of the tested plants. In conclusion, E. glaberrima maybe has relative low potential for developing as a medicinal plant. The aqueous extracts and leachate of E. glaberrima have the phytotoxic potential, exhibiting suppressive effect on some species underneath the Eurya vegetation in the field.

Results of mature embryo culture and somatic embryo induction of Picea morrisonicola Hayata were as follows: mature seeds were first treated with running water for 48 hours, then soaked in 70% ethanol solution for 2 minutes. Soaked in 4% NaOCl (supplemented 1% (v/v) Tween 20) and treated with ultrasonic shaker for 10 minutes. Mature embryos were them isolated from the seed and 10 mature embryos were transferred into 50 ml conical flask containing 20 ml MS solid culture medium. Callus with different phenotype were induced after they were culture under light and dark conditions respectively. Under light conditions, green and compact callus were formed, but yellow and soft callus were formed under dark. After yellow and soft callus were transferred to medium containing 2 ppm 2,4-D and 1 ppm BA, and cultured under dark conditions for 4 weeks, white and sticky embrygenic callus were induced. These callus contained precotyledonary phase somatic embryos with embryonal head and suspensor . Cotyledonary phase somatic embryos with green and short axis were induced after these callus were transferred onto MS solid medium supplemented with 1 ppm 2,4-D,1 ppm NAA and 2 ppm ABA and cultured at light conditions for 2 months.

Cinnamomum kanehirae is an important species of economic tree in Taiwan, but recently, the number of nature population was decreasing gradually. To save those plants, we used tissue planting instead of growing Cinnamomum kanehirae on this endangered tree. However, if we only lit the plants by fluorescent lamps in the progress of tissue culture, the cultivation process is very cumbersome and long cultivation period. The thesis used a dimmable lighting system for R-LEDs, G-LEDs and B-LEDs which provided light source for flask plantlet. The goals were first to find the optimal light combination to obtain the lowest period of cultivation, and second to verify the experiment with big data. Meanwhile, we took advantage of Orthogonal Array- in order to decrease the times of experiments- as a mathematical tool to work the studies. This research will focus on R-LEDs, G-LEDs and B-LEDs, and the on/off periods of these artificial lights. The results showed that the cultivation period of tissue culture plantlets was reduced by 80 days and 43%.

The aims of this thesis are selection and breeding of polyploids in Taiwan Jewel orchid, Anoectochilus formosanus Hayata. Plantlets derived from buds of stem nodes that treated with colchicine were used as the materials in this study. Firstly, putative polyploids were obtained through sequentially selections on the morphological characteristics including leaf morphology and plantlet diameter. Subsequently, stomata characteristics of these putative polyploids were analyzed. The parameters were size and frequency of stomata as well as the number of chloroplasts in guard cells. Finally, the ploidy level and chromosome numbers of 2x plants and putative polyploids were determined using flow cytometer. This thesis successfully selected autotetraploids of Taiwan Jewel orchid, which showed significantly higher plant height and diameter with a different leaf shape cordate when compared with leaf shape of 2x plants with ovate. In addition, these autotetraploids had significantly larger stomata size, lower stomata frequency, and higher numbers of chloroplast within guard cells when compared with the 2x plants. The selected polyploids could be used as materials for breeding, medicinal compositions analysis, mass propagation and practical production in the future.

The objectives of this study were to investigate the effects of colchicine treatments on the polyploidy induction of in vitro nodal and rhizome explants of Anoectochilus formosanus Hayata. First, three anti-microtubule chemicals colchicines, oryzalin, trifluralin at concentration of 25, 100 and 400 μM were added on proliferation medium to treat nodal explants for 2 weeks. Explants were transfered to the acclimatization medium after treatment and data of shoot proliftration and shoot length were collected 4 and 8 weeks after subculturing. The results indicated that all three chemicals inhibited shoot proliferation and growth and among them colchicines was the most effective one. The best polyploidy was induced from 400 μM of colchicines with 67% tetraploids and 33% octoploid, respectively. Various concentrations of colchicine in 0, 0.625, 1.25, 2.5 and 6.25 mM were added into proliferation medium. Nodal explants were treated with colchicine for 3 days before subculturing into an acclimatization medium and the data was collected ten weeks after treatment. The results showed that shoot proliferation, shoot length as well as survival rate of explants decreased along with increasing of colchichine concentrations. The highest percentage of tetraploid was obtained from 2.5 mM colchicine treatment with 80%. Various duration of 0, 3, 6 and 9 days for treatment with 2.5 mM colchicine in proliferation medium was compared. Shoot proliferation rate, shoot length and survival rate of nodal explants were all decrease as the increasing of treatment duration. The highest percentage of tetraploid(50%) was found in the treatment duration of 3 days. Rhizome explants age at 10, 11 and 14 weeks were used for polyploidy induction. Colchicine concentrations of 0, 0.025, 0.25 and 2.5 mM were added into medium for 3 days culturing. After colchine treatment, explants were subculture into a fresh medium for eight-weeks acclimation. Among three age explants, it was found that 10-week-rhizome had the hightst tetraploid induction rates from 10-50% in various concentration of colchicine. Moreover, The survival rates of rhizome explants were found decreasing as colchine concentration increased. Age of 13-week-rhizome explants were cultured in a medium containing with 0, 0.025, 0.25 and 2.5 mM colchicines for one week before subculturing into a solid fresh culture medium for eight weeks acclimation. The results showed that as concentration increasing to 0.25 and 2.5 mM, survival rates were decrease to 32.7 and 27.2%, respetively. However, a higher percentage of tetraploids, 30 and 20% was obtained from the 0.25 and 2.5 mM colchicine treatment. Colchicine of 0, 0.025, 0.25 and 2.5 mM were added into a solid or liquid culture medium for polyploidy induction using 12-week-rhizome explants. Treatment duration was last two weeks before subculturing into a fresh solid culture medium without colchicines for eight weeks acclimation. The results showed higher survival rates (21-35%) and percentages of tetraploids (5-30%) in liquid medium than that of in solid medium. Various treatment duration of 16, 24, 48 and 72 hr was compared using 10-week-rhizome culturing in a liquid medium containing 2.5 mM colchicine. The survival rates of explants decreased as the treatment duration increased. Treatment duration as short as 16 hr was found capable to induce tetraploid plants with 10% induction rate. Measurements of stoma size and its distribution density in leaves of polyploidy plants induced from anti-microtubule chemical treatment were conducted. A positive correlation between stoma size and ploidy level was obtained. Furthermore, the decreasing in stoma distribution density along with higher polyploidy level was also found. In conclusion the polyploidy induction experiments of in vitro A. formosanus Hayata in this study, using nodal explants culturing in a medium containing 2.5 mM colchicine for 3 days had the best result. The polyploidy level of regenerated plantlets was determined use young leaves by flow cytometry. Leaf stoma parameters observed by microscopy could also use for assistance polyploidy level detection.

Taiwan jewel orchid (Anoectochilus formosanus Hayata) is an indigenous Orchidaceae found in Taiwan. Extract of the whole plant had been applied for liver protection, anti-inflammation, pain relief, blood sugar reduction and blood pressure reduction. Taiwan jewel orchid had been confused and possibly be replaced by Ludisia discolor, A. koshunensis or Goodyera matsumurana, and Indonesian species in Taiwanese herbal markets. Because the whole plant morphology and outlooks of the mentioned herbs are not easily distinguished. In this study, molecular identification system for authentication of Taiwan jewel orchid had been established using 5.8S rDNA-ITS sequential difference analysis with PCR-RFLP based analysis, multiplex PCR techniques and bio-chip, ISSR (inter simple sequence repeats) and RAPD (Random amplified polymorphic DNA) molecular targeting. The results from 5.8S rDNA-ITS sequential difference analysis showed that the similarity between Taiwan jewel orchid and the “flaws” were between 90-99 %. However, Taiwan jewel orchid and the flaw species could also be distinguished with PCR-RFLP analysis by ApaL I、BssS I、BstB I and Ssp I restriction enzymes. By using specific designed primers and probes and comparing the differences of 5.8S rDNA-ITS between Taiwan jewel orchid and the flaws species with multiplex PCR and bio-chip. The result of ISSR primers and RAPD, 2 of them showed polymorphous bands patterns that were useful for distinguishing Taiwan jewel orchid from other “flaw” species after PCR amplification. This result indicated that the methods are more rapid, accurate and applicable in identification of Taiwan jewel orchid at the molecular level.

Polygonatum altelobatum Hayata plants of the genus Polygonatum Liliaceae, is a Taiwan''s endemic plant, strengthen lung function, lowering blood sugar, strong bones and muscles, antifatigue and delay many efficacy of human aging. The present study is to investigate the effect of aqueous extracts from root of Polygonatum altelobatum Hayata (TPAE) on amelioration of exercise-induced fatigue and oxidative stress in rats. Sprague-Dawley (SD) rats were divided into four groups including control (fed with drinking water) and three groups of different doses of TPAE (75, 150 and 375 mg/kg.bw). An exhaustive exercise test on a treadmill and the measurement of biochemical parameters related to fatigue were carried out after eight weeks. The results revealed that TPAE could extend significantly the endurance time to exhaustion, as well as decreasing the blood lactate and blood urea nitrogen (BUN) contents. Malondialdehyde (MDA) level of rats in PAHE treated groups were significantly decreased compared with that in the control group, while superoxide dismutase (SOD) and catalase (CAT) were significantly increased with comparison to that in the control group. The overall results indicated that PAHE had anti-fatigue activity with effective prevention of oxidative stress after exhaustive exercise and could elevate the exercise tolerance.

Cinnamomum insularimontanum Hayata is a medium-sized evergreen tree, which grows in Taiwan, Indonesia and neighboring regions. Since ancient times, cinnamons were known for their antipyretic and anti-inflammatory effects. With aromatic properties, cinnamons were widely used as spices, and also considered as economically important plants. Recent studies indicated that Lauraceae plants not only have antibacterial and antioxidative properties, but inhibition of cancer cell proliferation and diabetes glucose control, etc. However, rare studies on the chemical com-positions and antioxidative properties of C. insularimontanum Hayata have been explored. In this study, the antioxidant activities of the ex-tracts by different solvents from the leaves, branches, barks and stems of C. insularimontanum were studied. Various analytic assays, including DPPH radical scavenging capacity, reducing power, ferrous ions chelating assay, total phenols and flavonoids contents were determined. Results indicated that ethanolic extracts from branch and bark of C. insularimontanum had better DPPH radical scavenging capacity 89.11% and 87.94% clearance rate than others (p <0.05). In addition, aqueous ex-tracts from branch and bark of C. insularimontanum had better reducing power 1266.47 μg/mL AAE, ferrous ions chelating capability 95.32%, and 93.02% chelation rate than others (p <0.05). Extracts from bark of C. insularimontanum had highest total phenol contents 652.63 and 655.16μg/ mL GAE than others. On the other hand, extracts from leaves of C. insu-larimontanum had highest flavonoid contents 330.58 and 223.61μg/mL QE than others (p<0.05). In conclusion, antioxidant effects of extracts from branch and bark of C. insularimontanum were much better than others (p <0.05). The results of volatile analysis and antioxidant analysis showed that the GC/SM analysis of C. insularimontanum essential oil had the highest ratio of Eucalyptol among monoterpene compounds with the DPPH free radical scavenging ability of 79% clearance rate, and reducing power of 1266.47 μg/mL AAE (p<0.05). Essential oil had higher total phenol contents of 338.36 μg/mL GAE and higher flavonoid contents of 155.27 μg/mL QE (p<0.05). C. insularimontanum extracts could be de-veloped as more potentially economical applications in agricultural, cos-metic and food products in the future.

Master Hayao Miyazaki is a well-known animated director in the world. Not only are his works widely loved, but are translated into many languages. Furthermore, his works also spread in the world. Miyazaki’s works acquired a lot of recognitions of foreign awards. However, after four decades-long creative career, he announced that The Wind Rises would be the end of his lengthy animated career, and he would engage in the short animation production only. In Hayao Miyazaki’s works, we can find features such as unique camera angles, colorful and vivid images, youths and maidens, as well as environmental awareness and ecological conservation in stories. However, domestic researches for Hayao Miyazaki's works are confined to the features list above. A few other researchers make cultural cross reference their main themes. None of them bring in “Mythology” or “The Hero’s Journey” on their review. Therefore, this article,The Hero’s Journey in Hayao Miyazaki’s animations , will follow the concept of "Hero’s Journey", proposed by Joseph Campbell in his “The Hero’s With A Thousand Faces” to examine the six original works of Hayao Miyazaki, including Nausicaa of the Valley of the Wind, Laputa Castle in the Sky, My Neighbor TOTORO, Princess Mononoke, Spirited Away, and The Wind Rises. The symbol of works, prototype, significance of storyline, and the original prospect of "The Hero’s Journey" are the focus of this study.

Lignans, which are synthesized by dimerization of two C6-C3 units, exist abundantly in the wood of Taiwania cryptomerioides Hayata. Lignans in Taiwania, such as dimethylmatairesinol, taiwanin A and taiwanin E, were reported to have siginificant cytotoxic activity against tumor cells. As the key enzyme of lignan biosynthesis, pinoresinol-lariciresinol reductase (PLR) catalyzes the two-step reduction of pinoresinol to form lariciresinol and then to secoisolariciresinol. Secoisolariciresinol would next be oxidized by secoisolariciresinol dehydrogenase (SDH), and the product matairesinol is suggested to be the precursor for other downstream ignans. In this study, three PLR and six SDH candidate genes of T. cryptomerioides were identified by analysing the transcriptome of wood cambium, sapwood, transition zone and heartwood. The complete coding sequences (CDS) of each gene were obtained by rapid amplification of cDNA ends (RACE). Using Escherichia coli as the host, the heterologously expressed TcPLRs exhibited PLR activity, but the TcSDHs did not exhibited SDH activity. Among the three TcPLRs, TcPLR1 reduced pinoresinol to lariciresinol, while TcPLR2.2 and TcPLR3 reduced both pinoresinol and lariciresinol. The results of RT-PCR revealed that TcPLR1 most highly expressed in the wood cambium, and next in the heartwood. TcPLR2.2 and TcPLR3 both expressed in the wood cambium and the sapwood, while TcPLR2.2 showed slightly higher expression level in the cambium, and TcPLR3 mostly expressed in the sapwood. This study characterizes three PLRs of T. cryptomerioides, which involve in the biosynthesis of upstream lignans, and the expression pattern of TcPLR genes may provide information for identifying downstream lignan biosynthetic genes in the future.
