Resumen

<p><strong>Abstract.</strong> The application of different leaf physical models will result in the low accuracy in the process of the vegetation information inversion of the expressway, as well as poor efficiency in the process. The GLIBERTY model attempts to simulate the leaf reflectance and transmittance by the use of hierarchical computing theory, through the analysis of the optical properties of the single cell and the introduction of monolayer cells and cells of infinite layer between the reflectance and transmittance mathematical relationship, based on the radiative transfer theory. The study established the completed GLIBERTY model calculation theory system after the impaction of leaf structure parameters. The results show that the GLIBERTY model can accurately simulate the spectrum information of broadleaf and needle even in the case of less input parameters.</p>

Resumen

Despite the implications leaves have for life, their origin and development remain debated. Analyses across ferns and seed plants are fundamental to address the conservation or independent origins of megaphyllous leaf developmental mechanisms. Class I KNOX expression studies have been used to understand leaf development and, in ferns, have only been conducted in species with divided leaves. We performed expression analyses of the Class I KNOX and Histone H4 genes throughout the development of leaf primordia in two simple-leaved and one divided-leaved fern taxa. We found Class I KNOX are expressed (1) throughout young and early developing leaves of simple and divided-leaved ferns, (2) later into leaf development of divided-leaved species compared to simple-leaved species, and (3) at the leaf primordium apex and margins. H4 expression is similar in young leaf primordia of simple and divided leaves. Persistent Class I KNOX expression at the margins of divided leaf primordia compared with simple leaf primordia indicates that temporal and spatial patterns of Class I KNOX expression correlate with different fern leaf morphologies. However, our results also indicate that Class I KNOX expression alone is not sufficient to promote divided leaf development in ferns. Class I KNOX patterns of expression in fern leaves support the conservation of an independently recruited developmental mechanism for leaf dissection in megaphylls, the shoot-like nature of fern leaves compared with seed plant leaves, and the critical role marginal meristems play in fern leaf development.

Resumen

The asymmetric leaves2 (as2) mutant of Arabidopsis thaliana generated leaf lobes and leaflet-like structures from the petioles of leaves in a bilaterally asymmetric manner. Both the delayed formation of the primary vein and the asymmetric formation of secondary veins were apparent in leaf primordia of as2 plants. A distinct midvein, which is the thickest vein and is located in the longitudinal center of the leaf lamina of wild-type plants, was often rudimentary even in mature as2 leaves. However, several parallel veins of very similar thickness were evident in such leaves. The complexity of venation patterns in all leaf-like organs of as2 plants was reduced. The malformed veins were visible before the development of asymmetry of the leaf lamina and were maintained in mature as2 leaves. In vitro culture on phytohormone-free medium of leaf sections from as2 mutants and from the asymmetric leaves1 (as1) mutant, which has a phenotype similar to that of as2, revealed an elevated potential in both cases for regeneration of shoots from leaf cells. Analysis by the reverse transcription-polymerase chain reaction showed that transcripts of the KNAT1, KNAT2 and KNAT6 (a recently identified member of the class 1 knox family) genes accumulated in the leaves of both as2 and as1 plants but not of wild type. Transcripts of the STM gene also accumulated in as1 leaves. These findings suggest that, in leaves, the AS2 and AS1 genes repress the expression of these homeobox genes, which are thought to maintain the indeterminate cell state in the shoot apical meristem. Taken together, our results suggest that AS2 and AS1 might be involved in establishment of a prominent midvein and of networks of other veins as well as in the formation of the symmetric leaf lamina, which might be related to repression of class 1 knox homeobox genes in leaves.

Resumen

Foliar phenologies of forest understory plants were categorized, and the distribution pattern of leaf habit was examined among different forest environments. Various patterns of foliar phenology were found, especially in herbaceous plants. In addition to the seasonal light regime controlled by the phenology of canopy trees, differences in the length of period with snow cover led to the divergence. Perennial-leaved plants predominate in intensely shaded habitats while annual-leaved plants are more abundant in less shaded habitats. The shade tolerance of perenniel-leaved plants can be considered a preadaptation to snow tolerance. In contrast with the perennial-leaved plants, biennial-leaved plants with leaves overwintering 1 year appear to be favored in euphotic habitats with high insulation both in spring and in autumn. These species are effective competitors in spring because of rapid emergence of current leaves, probably through retranslocation of resources accumulated in the previous year. Another adaptive trait is found in heteroptic plants simultaneously having summer-green leaves and overwintering leaves; these types of leaves seem to function in predictable and quite different environments in a year. Key words: foliar phenology, growth form, light resource, overwintering leaf, snow cover.

Resumen

Master of Arts
Department of Modern Languages
Robert L. Clark
Medieval French literature provides the modern researcher with references to the healing arts in many passages that are incorporated into prose or poetic works. Because there was no clear separation of the genres into modern classifications, references to treatment of sicknesses of body, mind or spirit are woven into many literary works, providing us with a kind of snapshot of the state of the art healing practices of the day. Texts make reference to herbs and plants used to cure the ailments of the body, gardens and flowers that refresh the spirit, miraculous unguents, cures through the intercession of the saints and the Virgin Mary and surgical procedures. Texts examined here include Le Roman de la Rose, Erec et Enide, Aucassin et Nicolette, Les Lais of Marie de France, Le conte du Graal, Le chevalier de la charrette, La Condamnation de Banquet, Yvain, Cligès, La Chanson de Roland and Treize Miracles de Notre-Dame. The picture they provide of the medicine of the time has a certain charm and quaintness that many moderns seek in holistic treatments of today which hearken back to this more rustic medicine.

Resumen

”No one leaves behind” är en uppsats som diskuterar vilka berättarstrukturer och ideologier som kan urskiljas i de amerikanska krigsfilmerna Behind Enemy Lines (2001), Black Hawk Down (2001), We Were Soldiers (2001) och Saving Private Ryan (1998), med hjälp av teoretiska metoder från strukturalismen och teoretikern John Fiske. Dessutom behandlas även begreppet nationell identitet för att undersöka om man kan se någon tendens till nationella identiteter i de amerikanska krigsfilmerna.

Slutsatsen är att filmerna har en gemensam berättarstruktur och gemensamma teman som är viktiga för de ideologiska tankar och värderingar som kan urskiljas i filmerna. Teman såsom ära, mod och heder, det manliga förhållandet som i uppsatsen benämns brödraskap, och dessutom temat No one leaves behind vilket är mycket centralt i en del av filmerna. Ingen av soldaterna i filmerna skall lämnas kvar i en krigszon, levande eller död.

Resumen

The author presents the first detailed review of the pharmacological therapy of parkinsonism from ancient times until the near present (1980). It is not clear whether parkinsonism as it is now defined – a progressive neurodegenerative disorder of the basal ganglia characterized by sharply reduced striatal dopamine levels, particularly in the striatum – has always affected a significant minority of aged persons, but suggestive evidence to this effect in the older literature is reviewed. The major discussion commences, however, with the administration of various plant alkaloids to parkinsonian patients in the second half of the 19th century. Antiparkinsonian therapy since this time may be divided into a number of phases: 1. The employment of alkaloids derived from solanaceous plants: initially hyoscyamine, then hyoscine/scopolamine and atropine. The discovery and characterization of these alkaloids, and the gradual recognition that other pharmacologically useful solanaceous alkaloids (such as duboisine) were identical with one or other of these three compounds, is discussed. 2. With the outbreak of encephalitis lethargica following the First World War, parkinsonian patient numbers increased dramatically, leading to a multiplicity of new directions, including the use of another solanaceous plant, stramonium, of extremely high atropine doses, and of harmala alkaloids. 3. The so-called “Bulgarian treatment” was popularized in western Europe in the mid-1930s. It was also a belladonna alkaloid-based therapy, but associated with greater efficacy and fewer side effects. This approach, whether as actual plant extracts or as defined combinations of belladonna alkaloids, remained internationally dominant until the end of the 1940s. 4. Synthetic antiparkinsonian agents were examined following the Second World War, with the aim of overcoming the deficiencies of belladonna alkaloid therapy. These agents fell into two major classes: synthetic anticholinergic (= antimuscarinic) agents, such as benzhexol, and antihistaminergic drugs, including diphenhydramine. These agents were regarded as more effective than plant-based remedies, but certainly not as cures for the disease. 5. A complete change in direction was heralded by the discovery in 1960 of the striatal dopamine deficit in parkinsonism. This led to the introduction of L-DOPA therapy for parkinsonism, the first approach directed against an identified physiological abnormality in the disorder. 6. Subsequent developments have thus far concentrated on refinement or supplementation of the L-DOPA effect. Recent attempts to develop neuroprotective or -restorative approaches are also briefly discussed. The thesis also discusses the mechanisms by which the various types of antiparkinsonian agent achieved their effects, and also the problems confronting workers at various periods in the design and assessment of novel agents. The impact of attitudes regarding the etiology and nature of parkinsonism, particularly with regard to symptomatology, is also considered. Finally, the history of antiparkinsonian therapy is discussed in context of the general development of both clinical neurology and fundamental anatomical, physiological and biochemical research. In particular, the deepening understanding of the neurochemical basis of central nervous system function is emphasized, for which reason the history of dopamine research is discussed in some detail. This history of antiparkinsonian therapy also illustrates the fact that the nature of experimental clinical pharmacology has markedly changed throughout this period: No longer the preserve of individual physicians, it is now based firmly on fundamental laboratory research, the clinical relevance of which is not always immediately apparent, and which is only later examined in (large scale) clinical trials. It is concluded that antiparkinsonian therapy was never irrational or without basis, but has always been necessarily rooted in current knowledge regarding neural and muscular function. The achievements of L-DOPA therapy, the first successful pharmacological treatment for a neurodegenerative disorder, derived from the fruitful union of the skills and contributions of different types by laboratory scientists, pharmacologists and clinicians
Der Autor stellt die erste detaillierte Zusammenfassung der Entwicklung der pharmakologischen Therapie des Parkinsonismus vom Altertum bis in die jüngere Vergangenheit (1980) dar. Es ist nicht klar, ob der Parkinsonismus, wie er jetzt definiert wird – eine progressive neurodegenerative Störung der Basalganglien, die durch die zum scharf verringerten Dopamininhalt des Corpus striatum führende Degeneration der nigrostriatalen Bahn gekennzeichnet wird – zu allen Zeiten eine bedeutende Minderheit älterer Personen heimgesucht hat, verlockende Hinweise darauf findet man aber in der älteren Literatur. Die Hauptdiskussion beginnt jedoch mit der Anwendung verschiedener Pflanzenalkaloide bei Parkinson-Patienten in der zweiten Hälfte des 19. Jahrhunderts. Die Geschichte der Parkinson-Therapie seit dieser Zeit läßt sich in eine Serie von Phasen gliedern: 1. Die Anwendung von aus den Solanazeen isolierten Alkaloiden: zuerst Hyoscyamin, später Hyoscin/Skopolamin und Atropin. Die Entdeckung und die Charakterisierung dieser Alkaloide und die allmähliche Feststellung, daß andere pharmakologisch nützliche Solanazeen-Alkaloide (z.B. Duboisin) mit einem oder anderem dieser schon bekannten Mittel identisch waren, werden diskutiert. 2. Mit dem Ausbruch der Encephalitis lethargica nach dem Ersten Weltkrieg stieg die Anzahl von Parkinson-Patienten dramatisch an, was zu einer Vielfältigkeit neuer therapeutischer Richtungen führte: Der Einsatz des auch zu den Solanazeen gehörenden Stramonium, die Verabreichung von extrem hohen Atropindosen, und die Benutzung von Harmala-Alkaloiden waren insbesondere hochgeschätzt. 3. Die sogenannte “Bulgarische Kur” verbreitete sich schnell in Westeuropa in der Mitte der dreißiger Jahre. Es handelte sich dabei ebenfalls um eine auf Tollkirsche-Alkaloiden basierte Therapie, der jedoch höhere Wirksamkeit und wenige Nebenwirkungen zugemutet wurde. Diese Methode, vermittels der Verabreichung tatsächlicher Tollkirschenextrakte bzw. definierter Kombinationen von Belladonna-Alkaloiden, beherrschte die Parkinson-Therapie bis zum Ende der vierziger Jahre. 4. Nach dem Zweiten Weltkrieg wurden synthetische Parkinson-Mittel überprüft, in der Hoffnung, die Mängel der bisherigen anticholinergen Therapien überwinden zu können. Diese Mittel teilten sich in zwei Hauptkategorien ein: synthetische anticholinerge (= antimuskarine; z.B. Benzhexol) und antihistaminerge Mittel (z.B., Diphenhydramin). Diese Arzneimittel wurden als wirkungsvoller als pflanzliche Therapien angesehen, jedoch sicherlich nicht als Heilmittel für die Krankheit. 4. Eine gründliche Richtungsänderung der Parkinson-Therapie kündigte sich mit der Entdeckung (1960) des striatalen Dopamindefizits im Parkinsonismus an. Diese führte zur Einführung der L-DOPA-Therapie, der ersten Parkinson-Therapie, die gegen eine genau definierte physiologische Abnormität gerichtet war. 5. Die darauf folgenden Entwicklungen haben sich bis heute auf Verfeinerung bzw. Ergänzung des L-DOPA-Effektes konzentriert. Neuere Ansätze, neuroprotektive bzw. -restorative Therapien zu entwickeln, werden kurz behandelt. Die Arbeit diskutiert auch die Mechanismen, die der Wirksamkeit der verschiedenen Parkinson-Mittelarten zugrunde liegen, und auch die Probleme, die Forscher bei der Entwicklung und Bewertung neuartiger Mittel konfrontiert haben. Diese Diskussion zieht auch in Betracht die Auswirkung der Haltung des jeweiligen Forschers betreffend der Ätiologie und Natur des Parkinsonismus auf die Beurteilung neuer therapeutischer Möglichkeiten. Schließlich wird die Geschichte der Parkinson-Therapie im Kontext der allgemeinen Entwicklung der klinischen Neurologie als auch der grundlegenden anatomischen, physiologischen und biochemischen Forschung während dieser Periode behandelt. Insbesondere wird das wachsende Verständnis der neurochemischen Grundlagen der Funktion des Zentralnervensystems hervorgehoben, indem die Geschichte der Dopaminforschung ausführlich behandelt wird. Die Geschichte der Parkinson-Therapie weist auch darauf hin, daß sich die Natur der experimentellen Pharmakologie während dieser Periode grundsätzlich geändert hat. Sie liegt nämlich nicht mehr im Zuständigkeitsbereich des einzelnen Arztes, sondern wird im Gegenteil auf grundlegender Laborforschung aufgebaut, deren klinische Bedeutung nicht immer sofort deutlich ist. Erst später werden die Ergebnisse dieser Grundlagenforschung in großangelegten klinischen Versuchen bei Patienten überprüft. Es wird gefolgert, daß die Parkinson-Therapie zu keiner Zeit als ohne vernünftige Grundlage bzw. irrational betrachtet werden darf. Sie ist jedoch immer dem aktuellen Wissensstand betreffend neuraler und muskulöser Funktion entsprechend geregelt worden. Der Erfolg der L-DOPA-Therapie, der ersten langfristig wirksamen pharmakologischen Behandlung einer neurodegenerativen Krankheit, ist das Ergebnis der ertragreichen Vereinigung der Fähigkeiten und verschiedenartigen Beiträge von Grundlagenforschern, Pharmakologen und Klinikern

Resumen

Changes in chlorophyll content, carotenoid content and composition, abscisic acid and phaseic acid levels, hydrolytic enzyme activity and polypeptide pattern were monitored during senescence of the primary attached leaves of Hordeum vulgare L. cv. Dyan. Senescence occurred due to the normal course of leaf development or was induced by incubation of leaves in darkness. Loss of chlorophyll and total leaf protein was retarded in light whereas it continued rapidly in leaves from dark-incubated seedlings. Chlorophyll alb ratio increased with the progression of senescence, suggesting that chlorophyll b was referentially degraded during this process. Loss of total protein coincided with enhanced activity of acid and neutral proteases. In contrast, loss of chlorophyll was not accompanied by an increase in· peroxidase activity, suggesting that this enzyme was not responsible for initiating chlorophyll breakdown. Carotenoid and abscisic acid levels were monitored in the same tissue extracts. The results obtained show that the increase in endogenous levels of abscisic acid, induced by senescence, correlated with enhanced epoxidation of the xanthophyll cycle, ie., increased conversion of zeaxanthin to antheraxanthin and all-trans-violaxanthin. In addition, an increase in abscisic acid levels occurred concomitant with a decrease in all-trans-violaxanthin and 9'-cis-neoxanthin, suggesting an apparent 1:1 relationship on a molar basis. It is therefore proposed that enhanced abscisic acid production, due to foliar senescence, arises from fluctuations in carotenoid turnover. Polypeptide patterns in isolated chloroplasts, purified thylakoid and stromal fractions were very similar for leaves incubated in either light or darkness. A decrease in intensity of bands was observed in isolated chloroplasts and stromal fractions. Intensity of bands in thylakoids remained unchanged with the progression of senescence. Protein standards of peroxidase and lipoxygenase co-migrated with proteins of the isolated chloroplast. Although tentative, some proteins of the chloroplast may be representative of precursors of hydrolytic enzymes which are known to increase during senescence.

Resumen

The relevance of these studies was due to the need to clarify the biogeochemical characteristics of woody plant species that grow naturally on devastated lands. The object of this paper: to carry out a comparative analysis of macro nutrients and heavy metals contents in the leaves of trees spontaneously sprouting on the devastated lands at the Kryvyi Rih District. This research was performed at Petrovsky waste rock dump, the Central part of the Kryvyi Rih iron-ore & metallurgical district (Dnipropetrovsk region, Ukraine). The macronutrients (K, Ca, Mg, P and S) and heavy metals (Fe, Mn, Zn, Cu, Pb and Cd) contents in the leaves of three species of the trees (Ash-leaved Maple Acer negundo L., Silver Birch Betula pendula Roth. and Black Locust Robinia pseudoacacia L.) that were collected on devastated lands were assessed. It was established that trees which grow on the Petrovsky dump take place under evident shortage of nutrients (especially K and P) and excess of metals (especially Fe, Mn and Zn). Taking into account the revealed values of macronutrients optimal concentrations and revealed the heavy metals lowest content in the leaves, we assume that Ash-leaved maple and Black locust (compared to the Silver Birch) are more resistant to the geochemical conditions of devastated lands.
