Resumen

The Agelas genus sponges are widely distributed and provide shelter for organisms that inhabit reefs. However, there is a lack of research on the genetic diversity of the Agelas sponges. Additionally, only one Agelas mitochondrial genome has been documented, leaving the characteristics of the Agelas genus’s mitogenome in need of further clarification. To address this research gap, we utilized Illumina HiSeq4000 sequencing and de novo assembly to ascertain the complete mitochondrial genome of Agelas sp. specimens, sourced from the South China Sea. Our analysis of the cox1 barcoding similarity and phylogenetic relationship reveals that taxonomically, the Agelas sp. corresponds to Agelas nakamurai. The mitogenome of Agelas nakamurai is 20,885 bp in length, encoding 14 protein-coding genes, 24 transfer RNA genes, and 2 ribosomal RNA genes. Through a comparison of the mitochondrial genes, we discovered that both Agelas nakamurai and Agelas schmidti have an identical gene arrangement. Furthermore, we observed a deletion in the trnD gene and duplication and remodeling of the trnL gene in the Agelas nakamurai’s mitogenome. Our evolutionary analysis also identified lineage-specific positive selection sites in the nad3 and nad5 genes of the Agelas sponges’ mitogenome. These findings shed light on the gene rearrangement events and positive selection sites in the mitogenome of Agelas nakamurai, providing valuable molecular insights into the evolutionary processes of this genus.

Resumen

Hexanchus spp. are shark species that are often caught in the Indian Ocean southern Nusa Tenggara and its status is Near Threatened, but the information is still relatively limited. This study aimed to sex ratio, length-weight relationship and reproductive size of sixgill shark, Hexanchus spp. caught from southern Nusa Tenggara waters. This study had been carried out during 2016 at the Fishing Port of Tanjung Luar, East Lombok, West Nusa Tenggara. Shark data collection was done by measuring the length, weight, maturity and fishing data. Data were analyzed by formula of sex ratio, length-weight relationship, length at first maturity (Lm) and length at first catch (Lc). The results showed that Hexanchus spp. caught in the southern Nusa Tenggara waters consisted of H. nakamurai (81.82%) and H. griseus (18.18%). The sex ratio of both sharks was dominated by the female. The average of the total length of H. griseus (218.3 ± 96.08 cm). It was longer than H. nakamurai (127.6 ± 30.35 cm). The length-weight relationship of H. griseus was formulated as W = 0.0195 LT 2,6344 (R² = 0,9265) and H. nakamurai with the formula W = 0.002 LT 3,1098 (R² = 0.902). Both species have the size of Lm was bigger than the size of Lc which indicated to their population vulnerability.

Resumen

Bakteri gram negatif tetap menjadi ancaman serius bagi akuakultur, ekonomi, dan kesehatan manusia. Ironisnya, sementara antibiotik yang efektif belum ditemukan, resistensi bakteri ini terhadap berbagai antibiotik meningkat dengan kecepatan yang mengkhawatirkan. Hal ini menunjukkan urgensi penemuan antibiotik baru, terutama antibiotik yang dapat menghambat replikasi enzim seperti DNA gyrase atau topoisomerase IV, yang saat ini menjadi target baru penemuan antibiotik. Tujuan dari penelitian ini adalah untuk mengetahui potensi antibakteri Agelas nakamurai terhadap A. hydrophila, A. salmonicida dan E. tarda menggunakan ekstrak spons (1, 10, dan 100) mg/mL dan tetrasiklin (1 mg/mL) sebagai kontrol positif dan memprediksi potensi antibakteri dari agelasine A-F (1-6) dan agelasidine A (7) dari A. nakamurai dari Kepulauan Sangihe terhadap protein topoisomerase IV melalui docking molekuler. Uji in vitro dilakukan dengan menggunakan metode Kirby Bauer dengan sedikit modifikasi dan studi in silico menggunakan CB-dock 2 dan Protein Ligand Interaction Profiler. Meskipun ekstrak menunjukkan aktivitas antibakteri yang lebih lemah terhadap A. hydrophila, A. salmonicida dan E. tarda dibandingkan tetrasiklin, molekul docking dengan CB-dock 2 menunjukkan bahwa agelasine A-F (1-6) dan agelasidin A (7) memiliki afinitas pengikatan yang lebih kuat (-7.1). hingga -8,6 kJ/mol) daripada tetrasiklin (10), ciprofloksasin (11) atau levofloksasin (12) (-6,6 hingga -8,3 kJ/mol). Docking molekuler pada agelasidin C (9) dan D (10) juga menunjukkan afinitas pengikatan yang kuat (-8,3 dan -8,8 kJ/mol) ke protein target 1S16 terutama akibat ikatan hidrogen dan interaksi hidrofobik. Secara kolektif, hasil ini menunjukkan potensi agelasidin A, C dan D sebagai modulator dari target antibiotik baru, enzim topoisomerase IV.

Resumen

During the last three decades, secondary metabolites of marine origin have emerged as a significant source of bioactive compounds. Among the marine organisms explored, sponges offer a vast number of metabolites with unique structural diversity and a plethora of biological activities. Ageladine A, a fluorescent bromopyrrole alkaloid isolated from the marine sponge Agelas nakamurai, exhibited matrix metalloproteinase (MMP) inhibitory properties, as well as antiangiogenic activity. Due to this interesting biological profile, Ageladine A became, soon after its discovery, a target for total synthesis. In addition, a significant number of derivatives have been synthesized, and their biological activity was evaluated. The present review highlights all the successful efforts made towards the synthesis of Ageladine A. Furthermore, all the medicinal chemistry approaches to identify and assess new more potent inhibitors and to elucidate the structural features responsible for the activity are described.

Resumen

A conodont assemblage recovered from the middle part of the Santa Rosita Formation at Pantipampa (Iruya area, northwestern Argentina) is described herein. It includes Cordylodus angulatus Pander, C. cayesi Druce and Jones, C. lindstromi Druce and Jones, C. hastatus Barnes, Furnishina furnishi Müller, Kallidontus gondwanicus Zeballo and Albanesi, Phakelodus elongatus An, Phakelodus tenuis (Zhang), Proconodontus muelleri Miller, Semiacontiodus sp. and Teridontus nakamurai Nogami, which are characteristic of the Cordylodus angulatus Zone (upper lower Tremadocian). In the Iruya area, the C. angulatus Zone correlates with the trilobite Kainella meridionalis Zone and the lower part of the Kainella teiichii Zone. Taxonomic diversity and relative frequency of conodont species enables the recognition of the Semiacontiodus-Teridontus community, which is characteristic of shallow marine environments.

Resumen

Sponge makin banyak menarik perhatian para ilmuwan di seluruh dunia bukan karena potensi bioekologisnya saja tetapi juga karena potensi kosmetik dan biomedis dari molekul-molekul bioaktif maupun biomaterial sponge. Sangat disayangkan, pengetahuan tentang diversitas sponge di wilayah dengan biodiversitas tertinggi di dunia seperti Sulawesi Utara dan Wallacea pun masih sangat miskin dengan sebagian informasi diversitas sponge wilayah-wilayah ini tersebar dalam literatur-literatur ilmiah yang sudah usang dan terfragmentasi. Studi ini bertujuan untuk meningkatkan pengetahuan taksonomi dasar sponge di Sulawesi Utara khusunya di perairan Tahuna Kepulauan Sangihe sekaligus memberikan gambaran umum tentang distribusi dan potensi farmakologis dari sponges yang umum ditemukan di perairan Tahuna. Menggunakan metode acid digestion dan kombinasi mikroskop cahaya dan Corel Draw, kami mengidentifikasi tujuh spesies umum di terumbu karang Tahuna yaitu Agelas nakamurai, Clathria reindwardtii, Ircinia strobilina, Melophus sarasinorum, Speciospohongia vagabunda dan Xestospongia testudinaria. Selain menyentil tentang molekul-molekul bioaktif, tulisan ini juga secara singkat membahas tentang penyebaran ketujuh jenis sponge itu terutama di kawasan Asia Tenggara, selatan Jepang dan Australia untuk memperlihatkan sebaran sekaligus potensi kandungan bioaktif dan biomaterial dari sumberdaya laut amat berharga tetapi terabaikan dalam berbagai program monitoring dan konservasi terumbu karang di Indonesia ini. Sementara M. sarasinorum, S. vagabunda C. reinwardti, dan X. testudinaria terlihat memiliki distribusi sangat luas di wilayah Indo Pasifik, Agelas nakamurai dan I. strobilina sejauh ini baru dilaporkan di perairan Okinawa, Asia Tenggara dan Wallacea meskipun spesies serupa dari kedua genus itu terdistribusi hampir di seluruh Australia. Artikel ini mewakili laporan pertama tentang diversitas, kandungan molekul dan sebaran geografis sponge umum dari perairan Kabupaten Sangihe. Sponges have attracted considerable attention not only because of their bioecological but also due to cosmetical and medical potentials of bioactive compounds and biomaterials from sponges. Unfortunately, the basic knowledge of this impressive marine invertebrate, even in rich biodiversity region such as North Sulawesi, remains poorly known with such information scattered in old and fragmented literatures. This research aimed to increase the basic taxonomic knowledge and medical potential of seven sponges in Tahuna’s coral reefs Sangihe Islands as an step to encourage monitoring and concervation of this key species in coral reef in Sangihe Islands. Using acid digestion method and combination of light microscope and Corel Draw, we identified seven common species in Tahuna’s coral reefs namely reinwardti, Ircinia strobilina, Melophus sarasinorum, Speciospongia vagabunda and Xestospongia testudinaria. In addition to providing a quick review on the distribution of these species especially in South East Asia, southern Japan and Australia, the authors also touched on bioactive compounds produced by these animal isolated by one of the authors either from Sangihe Island’s sponges or sponges from other locations to give an overview of the bioactive potential and geographical distributions of the impressive but ignored marine resource in coral reefs’ monitoring and conservation programs in Indonesia. While sepecies such as M. sarasinorum, S. vagabunda C. reinwardti, and X. testudinaria seem to well distributed in Indopasific, A. nakamurai and I. strobilina are distributed only in south Japan and Wallacea regions although the sibling species of the two sponges have been well reported throughout Australia. This article represents the first report on biodiversity, distribution and bioactive molecules of sponges from Sangihe Islands.

Resumen

The problem of the critical number of pedestrians is significant in the study of lateral vibrations of footbridges since it can cause serviceability for the footbridges. By considering the pedestrians mass on the footbridge increases slowly, the modified Nakamuras model can be regarded as a fast-slow system which can be used to calculate the critical number of pedestrians. The influence of the time delay of interaction between pedestrians and the footbridge on the critical number of pedestrians is analyzed. Comparison with other results indicates the correctness of our formula predicting the critical number of pedestrians. Furthermore, our research suggests that the existence of the time delay can make the critical number of pedestrians less, which means that the time delay helps to improve the safety of the footbridge.

Resumen

Published behavioural, DNA sequence, and morphologic data on six populations of Mastigias, five from marine lakes and one from the lagoon, in Palau are summarized. Each marine lake population is distinguished from the lagoon population and from other lake populations by an unique suite of characteristics. Morphological differences among Mastigias populations in Palau are greater than those recorded between any previously described species of Mastigias, whereas molecular differences are far less (≤2.2% in COI and ITS1) than those found between medusae identified in the field as Mastigias papua (>6% in COI and ITS1). Thus, each marine lake population in Palau is described as a new subspecies of Mastigias cf. papua: remengesaui (in Uet era Ongael), nakamurai (in Goby Lake), etpisoni (in Ongeim'l Tketau), saliii (in Clear Lake), and remeliiki (in Uet era Ngermeuangel).

Resumen

Fermented bamboo shoots are rich in high protein, carbohydrates, fibre and minerals while low in fat content. In the North-East region of India and other Asian countries, they are mostly used in various food preparations. The present study was undertaken to explore the diversity of bacteria associated with Bamboo shoots and to evaluate their antibacterial profile. Based on the results the fermented bamboo shoots showed viable counts ranging from 6.55 ± 0.91 log CFU/g to 7.86 ± 1.21 log CFU/g. The 16s rRNA sequence analysis showed that these isolates belonged to the genus Bacillus (Bacillus safensis, B. tequilensis, B. siamensis, B. nakamurai, B. subtilis) and Enterobacter. These isolates have not been reported previously from fermented bamboo shoots except B. subtilis. Surprisingly, no Lactobacillus species or molds were found in any of the samples tested. Potent antibacterial activity was recorded against Klebsiella, Staphylococcus aureus, Salmonella and B. cereus.

Resumen

The conodont genus Teridontus was introduced in 1980 by Miller and was based on the Late Cambrian species Oneotodus nakamurai Nogami, 1967 from the Yencho Member of the Fengshan Fm. of northeast China. Teridontus was later reported from either the Upper Cambrian or Lower Ordovician (Landing et al., 1980; Miller, 1980; Landing and Barnes, 1981; Landing, 1983; An et al., 1983, 1985; Ni et al., 1983; Peng et al., 1983; Nowlan, 1985; Landing et al., 1986; Bagnoli et al., 1987; An, 1987; Buggisch and Repetski, 1987; Pohler and Orchard, 1990; An and Zheng, 1990; Seo and Ethington, 1993; Wang, 1993; Lehnen, 1994; Nicoll, 1994; Seo et al., 1994; Ji and Barnes, 1994; Taylor et al., 1996; Lehnert et al., 1997; Jia, 2000; Dubinina, 2000; Pyle and Barnes, 2002; Zeballo et al., 2005) sediments in numerous localities around the world, but a unanimous interpretation of the composition of the Teridontus apparatus organization was far from accepted.

Resumen

The larvae of 12 species of Copelatinae, Copelatus alternatus Sharp, 1882, C. caelatipennis princeps Young, 1963, C. glyphicus (Say, 1823), C. japonicus Sharp, 1884, C. masculinus Régimbart, 1899, C. nakamurai Guéorguiev, 1970, C. oblitus Sharp, 1882, C. parallelus Zimmermann, 1920, C. tenebrosus Régimbart, 1880, Exocelina australiae (Clark, 1863), E. ferruginea (Sharp, 1882), and Liopterus haemorrhoidalis (Fabricius, 1787) are described or redescribed, including for the first time a detailed chaetotaxy analysis of the cephalic capsule, head appendages, legs, last abdominal segment and urogomphi. A provisional parsimony analysis based on larval characteristics of 13 copelatine species was conducted using the program TNT, which reinforces the monophyletic origin of the Copelatinae. Copelatinae larvae stand out from the remaining Dytiscidae based on several synapomorphies, including the unusual shorter length of the mesothoracic legs. Legs and urogomphi morphology suggest that Copelatinae larvae studied evolved a creeping way of life. The provisional phylogenetic analysis presented in this study provides some arguments for the validity of the taxonomic status of the genera Liopterus Dejean, 1833 and Exocelina Broun, 1886.

Resumen

Hexanchiformes is regarded as a monophyletic taxon, but the morphological and genetic relationships between the five extant species within the order are still uncertain. In this study, we determined the whole mitochondrial DNA (mtDNA) sequences of seven sharks including representatives of the five Hexanchiformes, one squaliform, and one carcharhiniform and inferred the phylogenetic relationships among those species and 12 other Chondrichthyes (cartilaginous fishes) species for which the complete mitogenome is available. The monophyly of Hexanchiformes and its close relation with all other Squaliformes sharks were strongly supported by likelihood and Bayesian phylogenetic analysis of 13,749 aligned nucleotides of 13 protein coding genes and two rRNA genes that were derived from the whole mDNA sequences of the 19 species. The phylogeny suggested that Hexanchiformes is in the superorder Squalomorphi,Chlamydoselachus anguineus(frilled shark) is the sister species to all other Hexanchiformes, and the relations within Hexanchiformes are well resolved asChlamydoselachus, (Notorynchus, (Heptranchias, (Hexanchus griseus,H. nakamurai))). Based on our phylogeny, we discussed evolutionary scenarios of the jaw suspension mechanism and gill slit numbers that are significant features in the sharks.

Resumen

As long-living apex predators, sharks tend to bioaccumulate trace metals through their diet. The distribution of Al, As, Cd, Co, Cr, Cs, Cu, Fe, Mn, Ni, Pb, V, Zn and Hg in different tissues (muscle, liver, heart, gills and gonads) of large-size (58–390 cm) sharks, some of which rare, of the eastern Mediterranean Sea was studied. Trace metals analyses in samples originating from ten different Chondrichthyes species were performed by inductively coupled plasma–mass spectrometry (ICP-MS) and Cold Vapor Atomic Absorption Spectrometry (CVAAS) for Hg. Data on trace metal levels are for the first time reported herewith for the species O. ferox and H. nakamurai. Higher median concentrations of trace metals were generally determined in the liver. The concentrations of Hg, Cs and As in the muscle increased proportionally with body length. Statistically significant differences between sexes were recorded for Hg, Cr, Ni and As (p = 0.015) in the muscle tissues of P. glauca. Muscle tissue Hg concentrations exceeded the EU maximum limit (1 μg g−1 wet weight) in 67% of the individuals sampled, with the highest concentrations detected in O. ferox and S. zygaena, whereas regarding Pb (limit 0.30 μg g−1 ww), the corresponding percentage was 15%. Arsenic concentrations were also of concern in almost all shark tissues examined.

Resumen

Eleven new species of the genus Hatschekia Poche, 1902 (Copepoda: Siphonostomatoida: Hatschekiidae) are described based on female specimens from triggerfishes (Tetraodontiformes: Balistidae) caught in coastal waters of the Ryukyu Islands, Japan. These include Hatschekia hemicyclium n. sp. on Rhinecanthus rectangulus (Bloch & Schneider), R. aculeatus (L.) and R. verrucosus (L.); H. jonesi n. sp. on Sufflamen bursa (Bloch & Schneider) and S. fraenatum (Latreille); H. kabatai n. sp. and H. izenaensis n. sp. on Xanthichthys lineopunctatus (Hollard); H. churaumi n. sp. on Pseudobalistes flavimarginatus (Rüppell); H. zanpa n. sp. and H. fukurubi n. sp. on Balistapus undulatus (Park); H. mongarah n. sp. on Balistoides conspicillum (Bloch & Schneider); H. nakamurai n. sp. on Melichthys vidua (Richardson); H. mihkagan n. sp. on Odonus niger (Rüppell); and H. pseudobalistesi n. sp. on Pseudobalistes fuscus (Bloch & Schneider). Ten of the 11 new species, with the exception of H. fukurubi n. sp., share the intercoxal sclerites of legs 1 and 2 armed with 4 processes. This character differs from 87 of the known 97 species in Hatschekia. Of the 20 species with this character, the 10 new species are separated from each other mainly by the following morphological characters: the number of setal elements in the leg armature, on the antennule and the caudal ramus, the presence of posterior lobes on the trunk, the segmentation and form of the abdomen, and the length ratios of certain body parts.

Resumen

Bacteria under the operational group Bacillus amyloliquefaciens (OGBa) are all Gram-positive, endospore-forming, and rod-shaped. Taxonomically, the OGBa belongs to the Bacillus subtilis species complex, family Bacillaceae, class Bacilli, and phylum Firmicutes. To date, the OGBa comprises four bacterial species: Bacillus amyloliquefaciens, Bacillus siamensis, Bacillus velezensis and Bacillus nakamurai. They are widely distributed in various niches including soil, plants, food, and water. A resurgence in genome mining has caused an increased focus on the biotechnological applications of bacterial species belonging to the OGBa. The members of OGBa are known as plant growth-promoting bacteria (PGPB) due to their abilities to fix nitrogen, solubilize phosphate, and produce siderophore and phytohormones, as well as antimicrobial compounds. Moreover, they are also reported to produce various enzymes including α-amylase, protease, lipase, cellulase, xylanase, pectinase, aminotransferase, barnase, peroxidase, and laccase. Antimicrobial compounds that able to inhibit the growth of pathogens including non-ribosomal peptides and polyketides are also produced by these bacteria. Within the OGBa, various B. velezensis strains are promising for use as probiotics for animals and fishes. Genome mining has revealed the potential applications of members of OGBa for removing organophosphorus (OPs) pesticides. Thus, this review focused on the applicability of members of OGBa as plant growth promoters, biocontrol agents, probiotics, bioremediation agents, as well as producers of commercial enzymes and antibiotics. Here, the bioformulations and commercial products available based on these bacteria are also highlighted. This review will better facilitate understandings of members of OGBa and their biotechnological applications.

Resumen

The demand for chemical fertilizers in agriculture has increased to deal with the present global population increase. However, the excessive use of chemical fertilizers can be reduced by applying biofertilizers as an eco-friendly tool. Plant growth-promoting rizobacteria (PGPR) has an essential need in terms of fertilizer savings and promoting plant yield. Here, we study the effect of using three (PGPR) bacterial strains “Bacillus nakamurai MSRH1, Bacillus pacificus MSRH3, Paenibacillus polymyxa MSRH5”, integrated with chemical fertilizers (40, 60, 80, 100% need based NPK) on vegetative growth, yield production, and quality of table grapes ‘Flam Seedless’ grown in sand soil during two successive seasons of 2020 and 2021, with a preliminary trial season in 2019. Our results show that amending grapes with NPK in combination with the consortium of three strains led to significant improvement in colonized vines compared to a single application of 100% NPK. Results showed that bacterial consortium combined with 80% and 60% NPK mineral fertilizer had more positive effects than un-inoculated vines in growth parameters, cluster characteristics, yield/vine and berry quality in the two growing seasons. Besides, N, P and K concentrations of leaf petiole, total leaf chlorophyll content, and carbohydrates in canes were significantly enhanced by bacteria consortium with 80% and 60% PK chemical fertilizers. PGPR significantly increased total bacterial count, N2-fixing, P- solubilizing and K-solubilizing bacteria in soil treated with the three strains of bacteria plus mineral fertilizer. In addition, dehydrogenase and phosphatase activity in the rhizosphere soil were also increased in treatments inoculated with strains plus mineral fertilizer. The field study results showed that PGPR approach has potential and can be considered as a crop management strategy to increase the yield and quality of grapes, reduce chemical fertilization and subsequent environmental pollution, and could be useful in terms of sustainable production.

Resumen

AbstractTwo completely dissimilar faunal changes occur between the Sunwaptan and Skullrockian Stages (Ptychaspid and Symphysurid ‘Biomeres’) in the uppermost Cambrian on the east Laurentian craton. An undolomitized section in the Little Falls Formation in Washington County, New York, shows a typical ‘biomere’ extinction, with highest Sunwaptan trilobites followed by the abrupt appearance ofCordylodus proavusZone conodonts and the lowest post-extinction trilobites (ParakoldinioidiaEndo) 5.0 m higher. This stage boundary interval is very condensed by comparison with coeval Great Basin and Texas sections. Approximately 70 km southwest, typical pre-extinction taxa (the catillicephalidAcheilopsUlrich and several dikelocephalid species) are shown for the first time to persist well beyond the extinction as they occur with middleC. proavusZone conodonts (Clavohamulus elongatusor, more likely,Hirsutodontus simplexSubzone). The Ritchie Limestone member of the uppermost Little Falls Formation yields a succession of conodont faunas that spans theC. elongatus–H. simplex–Clavohamulus hintzeiSubzones (middle–upperC. proavusZone). These data prove that the trilobites are a relict fauna that persisted into theSymphysurinaZone of the Skullrockian Stage. The massive (burrow-churned), mollusc-dominated Ritchie Limestone, with the second Upper Cambrian cephalopod locality in east Laurentia, represents an inner-shelf refugium for Sunwaptan trilobites that has not been previously encountered. Final extinction of typical Sunwaptan clades is at least locally diachronous, and a simple, genus-based approach to trilobite biostratigraphy in the Cambrian–Ordovician boundary interval is untenable. The relict fauna appears to be distinct at the species level, so it is likely that a viable, species-based biostratigraphy can be developed.Teridontus gallicusSerpagliet al. 2008 is a synonym ofT. nakamurai(Nogami, 1967), andT.?francisiLanding sp. nov., with a large base and tiny cusp, is a lowerC. proavusZone form. New trilobites areAcheilops olbermanniWestrop sp. nov. andParakoldinioidia maddowaeWestrop sp. nov. The lowest Ordovician ‘Gailor Dolomite’ is a junior synonym of the Tribes Hill Formation, and the Ritchie Limestone is assigned to the top of the terminal Cambrian Little Falls Formation.

Resumen

Breast cancer is now one of the leading causes of death in women worldwide. Finding a cure is, therefore, critical for women’s health. Marine sponge-derived drugs have gained interest in breast cancer treatment. The development of marine natural products into cancer therapy includes several stages. It starts with the screening using the cytotoxic test method, a preclinical trial using the animal mode, and clinical trial phases I and II. In this study, we focus on the basic cytotoxic test to find the new source of anti-breast cancer compounds derived from Agelas nakamurai to know the potential for further investigation to become lead compounds. However, the anti-breast cancer potential of the Indonesian marine sponge A. nakamurai has never been studied. This study aimed to evaluate the anti-breast cancer potential of extract and fraction of A. nakamurai against epithelial human breast cancer cells (MDA-MB-231 and MCF-7 cells line) and to preliminary profile the known active compounds. The maceration using methanol was used for extraction and followed by partitioning with varied solvents [ethyl acetate (EtOAc), butanol, and water]. Fractionation was done using normal phase open column chromatography, and liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) was used for analyzing compounds. MDA-MB-231, MCF-7, and HEK-293 cell lines were used for biological activities. The chromatographic separation of the EtOAc fraction led to the F7 subfraction which strongly inhibits proliferation against the MDA-MD-231 (IC50: 10.677 μg/mL), MCF-7 (IC50: 15.154 μg/mL), and HEK-293 cells line. The LC-MS/MS data of active fraction F7 contained gelatin-D and ageloxime-D. This study reported that fraction 7 of A. nakamurai showed strong activity against MDA-MB-231, MCF-7, and HEK-293 cell lines. Further analysis will be carried out to know the mechanisms of action of active compounds.

Resumen

Previous studies of habitat suitability of sessile organisms on subtidal rocky substrata have been focused only one or two terrain attributes. In this study, we propose a new method to construct a centimeter resolution seafloor topographic model by using underwater photogrammetry to obtain multiple terrain variables and to investigate relationships between the distribution of sessile organisms and multiple terrain variables. Point cloud models of five square sections (11.3–25.5 m2) of the bedrock surface of Otsuchi Bay were reconstructed with a 0.05 m resolution. Using the 0.01 m resolution point cloud models, five terrain variables were calculated on each face of the mesh models: height above seafloor, topological position index, slope, aspect, and ruggedness. The presence/absence data of four species of sessile organisms (ascidian Halocynthia roretzi, barnacle Balanus trigonus, polychaete Paradexiospira nakamurai, and articulated coralline algae Pachyarthron cretaceum) were located on the mesh models. H. roretzi and B. trigonus were more abundant on vertical and high faces above the seafloor, and P. nakamurai were more abundant at high faces above the surroundings. In high position where the current velocity increases, the three sessile animals may have an advantage for their suspension feeding. In contrast, P. cretaceum, unlike the other three sessile animal species, occurred at various heights and on gentle slope faces suitable for photosynthesis.

Resumen

The field of systematics and our understanding of phylogenetic relationships have been invigorated by the use of molecular data, but analyses based on DNA sequence data are not always corroborated by diagnostic morphological characters. In particular, several taxonomic changes in butterflies (Papilionoidea) have been made solely on the basis of molecular data without identifying morphological synapomorphies that might have aided in diagnosing taxa from butterfly collections or specimens with no accessible DNA. We here focus on the butterfly genus Pseudodebis Forster, 1964 in the so-called ‘Taygetis clade’, which is one of the major clades in the diverse Neotropical nymphalid subtribe Euptychiina. We inferred the evolution of a male genitalic character using the most comprehensive molecular phylogeny for the ‘Taygetis clade’ to date. This approach allowed us to identify a synapomorphy for Pseudodebis Forster, 1964, which can be used to morphologically diagnose this genus and to distinguish it from other genera in the ‘Taygetis clade’. In addition, we describe two new species of Pseudodebis, P. nakamurai Nakahara & Willmott, sp. nov. and P. pieti Nakahara & Willmott, sp. nov., recovered as sister species based on molecular data, with an estimated time of divergence of 0.3 Ma (Bayesian confidence interval 0.03–1.61 Ma). Despite the low genetic divergence between these two Pseudodebis species, they can be readily distinguished by wing morphology. Pseudodebis nakamurai, sp. nov. and P. pieti, sp. nov. occur in partial sympatry across an elevational gradient along the western Andes, and the inferred recent speciation event might be related to a shift in elevation and possibly a change in larval hostplant preference. urn:lsid:zoobank.org:pub:38B4AF76-79E9-4D4D-BF16-FCD8F53A7277

Resumen

Salinity is one of the most vicious environmental factors controlling the productivity of crop plants as most of the crop plants are sensitive to salinity affected by high concentrations of salts in the soil. The objective of this study was to evaluate the influence of the inoculation with the encapsulated and liquid culture of three halo-tolerant plants growth-promoting rhizobacteria (PGPR) strains of Paenibacillus polymyxa MSRH5, Bacillus nakamurai MSRH1 and Bacillus pacificus MSR H3 on the growth and yield of wheat (Triticum aestivum L.). The three strains MSRH1, MSRH3 and MSR H5 were characterized as salt-tolerant bacteria. P. polymyxa MSRH5 had nitrogen fixation ability while B. nakamurai MSRH1 and B. pacificus MSRH3 were able to solubilize phosphate and K respectively. All strains can produce indole acidic acid (IAA) and exopolysaccharides (EPS) under saline conditions. Encapsulated beads were observed under Scanning Electron Microscope (SEM). Colonization of encapsulated bacteria on the root of the wheat plant was studied by Transmission Electron Microscopy (TEM). Under soil salinity conditions in two consecutive field tries, results cleared that strains in two forms succeed to colonize the plant root, the reduction in shoot proline was 35.8% with capsules inoculation as well as improved relative water content (%) to 60.57% and improved the electrolyte leakage recorded 18.1% respectively compared to control. Generally, halo-tolerant PGPR inoculation increased DHA (?), acidic and alkaline phosphatase activities compared to control, inoculation with capsules exhibited a reduction in catalase enzymes 46.00%, 37.5% in ascorbate peroxidase and 40% in superoxide dismutase respectively in shoots of the wheat plant. There is a significant increase in all yield parameters, the highest plant height 115.8 cm, spike length 21 cm and 1000 grains 71.3 g respectively recorded with capsules inoculation, it had considerable effects on the content of N, P, K and Na in shoots of wheat plants and reduced the value of Na/K ratio in all treatments inoculated compared to un-inoculated wheat plant.
