description: Four new α-pyrone derivatives, nodulisporipyrones A–D (1–4), were isolated from the extract of an endolichenic fungal strain Nodulisporium sp. (65-12-7-1) that was fermented with rice. The structures of 1–4 were elucidated by extensive spectroscopic analysis, and the absolute configurations were determined by modified Mosher's method and electronic circular dichroism experiments. Their antimicrobial activities against Staphylococcus aureus 209P, Escherichia coli ATCC0111, Aspergillus niger R330, and Candida albicans FIM709 were evaluated using a paper disk diffusion method. Nodulisporipyrones A–D (1–4) are the first α-pyrone derivatives from Nodulisporium fungi.

description: Ziziphus jujuba (jujube) of buckthorn family (Rhamnaceae) is an important medicinal crop plant cultivated in different provinces of Iran. It has also wild populations in some geographical areas. We carried out population genetic study on 8 populations of cultivated versus wild jujuba by using ISSR molecular markers to produce data on population genetic structure, gene flow, and genetic variability in the studied populations. We also aimed to investigate genetic differentiation between wild and cultivated plants and identify the potential gene pools of this medicinal plant species. The studied populations had a moderate genetic variability and were grouped in two major groups by PCoA plot. AMOVA revealed significant genetic difference among these cultivars. Mantel test showed significant correlation between genetic distance and geographical distance in the studied populations. PCoA analysis showed genetic differentiation between wild and cultivated plants within each province. STRUCTURE analysis identified two potential gene pools for jujube cultivars. Data obtained may be used in genetic conservation and future breeding programs of this medicinal plant species in the country.

description: This paper concerns the karyological analysis of fourteen mole rats collected in four different localities of North-Iraq (Kurdistan Region). The result showed that they belong to the following cytotypes of Nannospalax ehrenbergi: «Duhok-Bardarash Population» 2n = 52, NF = 76, and NFa = 72 and «Arbil-Sulaimania-Kirkuk populations» 2n = 52, NF = 80 and NFa = 76. The karyotypes of the Duhok population are similar to those from Mosul, but the Arbil-Sulaimania-Kirkuk populations’ karyotype represents a new chromosomal form. Their distribution extends from North Iraq to Sulaimania.

description: Halide perovskites are exciting candidates for broad-spectrum photocatalysts but have the problem of ambient stability. Protective shells of oxides and polymers around halide perovskite nano- and micro-crystals provide a measure of chemical and photochemical resilience but the photocatalytic performance of perovskites is compromised due to low electron mobility in amorphous oxide or polymer shells and rapid charge carrier recombination on the surface. Herein an in situ surface passivation and stabilization of CsPbBr3 nanocrystals was achieved using monolayered graphenic carbon nitride (CNM). Extensive characterization of carbon nitride protected CsPbBr3 nanocrystals (CNMBr) indicated spherical CsPbBr3 nanoparticles encased in a few nm thick g-C3N4 sheets facilitating better charge separation via percolation/tunneling of charges on conductive 2D nanosheets. The CNMBr core-shell nanocrystals demonstrated enhanced photoelectrochemical water splitting performance and photocurrent reaching up to 1.55 mA cm−2. The CNMBr catalyst was successfully deployed for CO2 photoreduction giving carbon monoxide and methane as the reaction products.

description: The current paper analyzes the male meiotic behavior in wild populations of Buddleja iresinoides and Castilleja arvensis from Piedmont areas of the Northwest Region of Argentina. Castilleja arvensis showed tetraploid number of chromosome of 2n = 24. Our results are not in agreement with the previously reported base number x = 19 for Buddleja and the chromosome number n = 28 found for B. iresinoides is atypical in the genus. Around 7 % pollen mother cells were aneuploid as they showed meiotic chromosome count of n = 20-21 bivalents. Possible origin for such atypical chromosome number has been discussed in this paper. During the cytological studies we also came across pollen mother cells showing meiotic abnormalities such as cytomixis, chromatin stickiness and anaphase bridges with lagging chromatin. Consequently microsporogenesis was also irregular showing dyads and triads. However, the percentage of these irregularities during meiosis and microsporogenesis was not higher, and pollen fertility was not affected to a great extent. Cytomixis and other meiotic abnormalities in these species are reported here for the first time.

description: Interpenetrating polymer network (IPN) hydrogels based on chitosan (CS) and poly(acrylic acid) (PAA) were prepared by one-pot strategy. The hydrogels exhibited porous structure and enhanced mechanical strength due to the entrapment of the two polymeric networks in the IPN. The ability of the hydrogels to adsorb basic dye Nil Blue (BB 12) from aqueous solutions was assessed using UV-VIS spectrophotometer. The adsorption amount was pH dependent, and the maximum adsorption capacity was observed at pH 10.0. The adsorption equilibrium was achieved within 45 minutes and the adsorption process could be well described by the pseudo-second-order kinetic model and Langmuir isotherm. Furthermore, the synergistic interactions between dyes and the two polymeric networks in the IPN were found during the adsorption process. Thermodynamic parameters revealed the dye sorption was an endothermic and spontaneous process with increasing randomness at the hydrogel/solution interface. Finally, studies on the reproducibility suggested that the hydrogel could be repeatedly used without any significant loss of the adsorption capacity.

description: The aim of this study is to determine the histochemical and biochemical changes that occurred during flower development in the stigmas of Hibiscus syriacus. The flower development of H. syriacus was divided into three successive stages; pre-anthesis, anthesis, post-anthesis, and stigma development was examined in parallel with these stages. At pre-anthesis, the stigmatic papillae cells covering the surface of the stigma were ovoid and their dense cytoplasm were rich in insoluble polysaccharide, protein and lipid. At anthesis, papillae cells grew and the pellicle layer becomes clear indicating dry-typed stigma. Meanwhile some sub-papillae cells, which accumulate dense organic matter from the beginning of development, began the process of autolysis and release their cellular content into the intercellular space. Whereas the organic matter content of papillae decreased at post-anthesis, it was still more than pre-anthesis stage. Similarly, peroxidase and non-specific esterase activity were very intensive at anthesis stage and activities were still remarkable at post-anthesis stage. The maximum CAT, SOD activity, H2O2 and MDA content were also determined at anthesis. Our results revealed that stigma of H. syriacus is receptive at anthesis and still conserve its receptivity at post anthesis assisting pollen germination and pollen tube growth.

description: L’enquête débute par le récit de l’informatrice sur son expérience de l’allaitement et de ses premières montées de lait pour ses trois grossesses. L’informatrice est mère de trois enfants. Elle raconte qu’elle a donné le sein environ une heure après la naissance. Elle ajoute que pour ses enfants la période d'allaitement a duré plus ou moins deux ans pour chacun. L’informatrice raconte qu’elle a toujours accouché à la maison et qu’elle n’a jamais été séparée de son enfant à la naissance. L’informatrice explique qu’avant la première tétée elle avait l’habitude de donner à l’enfant de la verveine avec un peu de sucre, de miel ou du jus de dattes. Elle répond aux questions de l’enquêtrice au sujet du colostrum : elle lui attribue la couleur jaune à la différence du lait maternel qui est blanc. Concernant le goût du colostrum, l’informatrice ne l’a pas goûté mais ses filles aînées lui ont rapporté qu’il avait un goût sucré. L’informatrice explique que le colostrum est très nourrissant pour l’enfant par rapport au lait maternel. L’informatrice évoque la durée du colostrum qui n’excède pas deux jours mais rapporte que certaines mères l’observent durant les quarante premiers jours qui suivent la naissance. D’après l’informatrice toutes les femmes produisent du colostrum. Elle ajoute que les prescriptions coraniques conseillent une période d’allaitement de deux ans. Le cas des frères et sœurs de lait liés par le colostrum est évoqué, ainsi que les moyens utilisés pour favoriser la montée de lait de la mère. À la fin de l’enquête, l’informatrice aborde rapidement les premiers soins qui sont donnés à l’enfant et les rapports intimes durant la période d’allaitement. L’entretien se termine en passant rapidement sur la question de la mortalité infantile et sur le don de colostrum animal. L'informatrice précise qu’il n’est pas donné au nouveau-né mais que le lait de chèvre peut faire partie de son alimentation.

description: Plasmonic hot carriers with a nonthermal distribution of kinetic energies have opened up new avenues in photovoltaics, photodetection and photocatalysis. While several articles have reported ultrafast hot electron injection from coinage metals into n-type semiconductors across Schottky barriers and efficient subsequent utilization of injected hot electrons, reports of hot hole harvesting are comparatively rare due to the difficulty in forming Schottky junctions between p-type semiconductors and high work function metals. In this work, we report the fabrication, characterization and theoretical calculations of a novel integrated multiferroic-plasmonic system comprising YMn2O5 nanowires decorated on their surface with Ag nanoparticles (NPs). A Schottky barrier for holes exists at the YMn2O5–Ag hetero-interface and hot holes are injected from Ag across this barrier. The synthesized hybrid along with bare Ag NPs were tested for Raman surface photocatalytic reduction of 4-NBT (4-nitrobenzenethiol) to DMAB (p,p′-dimercaptoazobenzene) where the composite demonstrated superior activity compared to the bare metal. Ultraviolet photoelectron spectroscopy (UPS) revealed a significantly reduced work function of the composite compared to the pristine Ag, indicative of more energetic hot electrons on the surface of the composite required for efficient photoreduction. Density functional theory (DFT)-based calculations revealed localization of molecular orbitals supportive of a possible hole transfer from YMn2O5 to Ag and a reorganization of electronic states, which promotes increased phonon-mediated sp-intraband damping of the plasmon. DFT results also indicated a purely electronic contribution to the ferroelectric polarization of YMn2O5 over and above the ionic contribution, which originated from the magnetic polarization of O2p states.

description: The chromosome counts of 13 species of family Apocynaceae in the flora of Egypt have been reported; one species from subfamily Periplocoideae and the other 12 species from subfamily Asclepiadoideae. The chromosome numbers are 2n = 22 for Periploca angustifolia, Glossonema boveanum, Pentatropis nivalis, Cynanchum acutum, Calotropis procera, Gomphocarpus sinaicus, Pergularia daemia and Pergularia tomentosa; 2n = 24 for Leptadenia arborea and Solenostemma arghel; 2n = 22, 44 for Caudanthera edulis, Caudanthera sinaica and Desmidorchis acutangulus. The chromosome numbers and karyotype analyses were firstly reported in Leptadenia arborea (2n = 24). The polyploid nature was demonstrated by the prevalence of cells with 2n = 4x = 44 chromosomes in Caudanthera edulis, Caudanthera sinaica and Desmidorchis acutangulus. The chromosomes are median and submedian as most species in the Apocynaceae. The intrachromosomal asymmetry and interchromosomal asymmetry were estimated with MCA and CVCL values. In intrachromosomal asymmetry, Desmidorchis acutangulus is the most symmetrical karyotype, while Pergularia tomentosa is the most asymmetrical karyotype. In interchromosomal asymmetry, Glossonema boveanum is the most symmetrical karyotype, while Cynanchum acutum is the most asymmetrical karyotype.

description: Nine natural populations of subterranean clover (Trifolium subterraneum L.) coming from different eco-geographical sites of the North-East Algeria, have been studied for their chromosome number and karyotype features. The study is part of the evaluation and valorization of plant genetic resources of fodder and pastoral interest in Algeria. The results of mitosis detect two groups of populations, and reveal diversity in the number among and within populations. The Algerian populations of T. subterraneum are characterized by two chromosomic formulas. The first formula (2n=2x=16m) (median), more common in most of the studied populations, is in conformity with previous reports in this species. The karyotype of these populations is symmetrical for size and form. The second (2n=2x= 18m), is detected for the first time and described as a new chromosomal formula in T. subterraneum. The latter is relatively more frequent than the first one and characterizes the populations coming from high altitude areas. The karyotype (2n=2x=18m) is relatively symmetrical. At the level of the two established Karyotypes, satellites are highlighted at the first pair. A variation in the size and frequency of these satellites is observed. The species exhibits regular meiotic behaviour, confirming the presence of two basic chromosome numbers (x=8 and 9). The study also highlights the role of ecological factors (Altitude and Rainfall) of the originating environment of Algerian populations in the variation and evolution of chromosome numbers in T. subterraneum. The new cytogenetic data can be exploited in the taxonomy of the species in Algeria in order to select and develop this plant genetic resource in the agricultural field.

description: Genome size is very useful in studies regarding taxonomy, evolution, and reproductive biology in many animal groups, including insects. Herein, we assembled the information about genome size in ants, compiling the DNA content estimated so far, in order to evaluate the methods, the tissues and the internal standard applied to estimate the genomes size. All values were placed in a phylogenetic tree to put it in an evolutionary context and the means of the subfamilies were further compared statistically to investigate changes and trends in the variation across taxa. The compiled data resulted in 86 specimens of ants, comprising 69 different species. This number represents 0.52% of the total number of 13,369 ant species described, covering only 40 from 333 valid extant genera. The average Formicidae genome size was 0.36 pg (± 0.13). Most of the estimates were obtained through flow cytometry (83.5%), commonly using brain tissues, with Drosophila melanogaster as internal standard (76%). Differences in DNA content of ant species may be related to differences in the amount of heterochromatin and is not related with chromosome number. The evaluation of the genome size estimations currently available for ants has highlighted their scarcity. Such information would be valuable as independent data for the study of ant diversity and evolutionary biology. Further, we conclude that the standardization of the techniques used and a large–scale study on ant genome size are urgently required, given the importance of this insect group and the needs for the improvement in our knowledge on ant genome.

description: Background: Therapeutic communities (TCs) maintain order and encourage behavior change through a system of peer corrections. This study is the first quantitative analysis of the dynamics of the exchange of peer corrections at TCs. Objectives: We applied longitudinal social network analysis to compare the reactions of TC residents to peer versus staff intervention, while analyzing dynamics of correction exchange among residents. Method: The data consisted of a large database of staff and peer affirmations and corrections at four therapeutic community units that occurred between the years 2006 and 2008. We modeled the data as a directed temporal social event network, using a generalized linear mixed effects model to analyze predictors of corrections among residents. Results: Residents were more likely to send a correction following peer affirmations and corrections than following staff affirmations and corrections. Residents reciprocated corrections to individual peers. Autocorrelation was evident in both sending and receiving corrections and residents were more likely to send a correction after having sent an affirmation. Residents who arrived at roughly the same time were more likely to exchange corrections. Residents tended to send and receive more corrections in the middle 3 months of their treatment. European American residents and those with higher scores on the LSI-R were more likely to receive corrections than others. Conclusions: TC residents respond more strongly and more positively to peer than to staff intervention. The pattern of exchange of peer corrections in TCs is complex. This suggests possible paths to improved outcomes.

description: The Pacific oyster Crassostrea gigas is a potential model organism of bivalve mollusks. Comprehensive studies on the proteome of its sperm are necessary to expand our understanding on its reproduction and development, which however are still poor currently. In this study, to improve the situation, we conducted a proteomic analysis on the sperm based on two-dimensional electrophoresis combined with protein identification through mass spectra data. Fifty-six protein spots with constant and relatively high expression levels were selected for protein identification. Among them, 36 were identified (corresponding to 31 proteins), including cytoskeletal proteins, proteins involved in energy supply, protein modifiers, signal regulators, antioxidant proteins, and others. We proposed that these proteins might play important roles in sperm motility, gamete interaction, and oxidation resistance. In particular, we observed several heat shock proteins that were proved to play essential roles in animal sperms. A further immunofluorescence experiment revealed a mitochondria localization of Hsp60s and wide distributions of Hsp70s, indicating these proteins might function in various processes such as mitochondrial function, gamete interaction, and regulation of receptor activity. Our data will provide fundamental supports for the studies on the mechanisms of fertilization and contribute to expand the understandings on reproduction and development of bivalve mollusks.

Cultured kidney cells from four brown trout subspecies (Salmo trutta abanticus, S.t. caspius, S.t. fario and S.t. labrax) and their reciprocal hybrids were karyotyped using conventional staining, C-banding and Ag-NOR staining techniques. Chromosome number (2N) and chromosome arm number (NF) ranged from76 to 80 and 98 to 102, respectively. Silver staining revealed the presence of NOR sites on the short arm of the submetacentric chromosome. The size and number of NOR sites showed uniformity. The presence of heterochromatin on different chromosome arms was confirmed by C-banding. The presence and position of constitutive heterochromatin showed variability among individuals. Chromosome structures of purebred brown trout subspecies belonging to the Danubian linage and their hybrids were similar, and no distinctive characteristics were observed in any of the species. The results of this study are applicable to the development of improved conservation and management strategies for brown trout.

description: In order to understand the differentiation of staminate flowers of pecans (Carya illinoensis (Wangenh.) K. Koch), we carried out an integrated study of staminate flower development in a protogynous cultivar, Mahan, by assessing changes in external morphology and microstructure at multiple levels. Results showed that the staminate inflorescence differentiation cycle for pecans was 1 year. Staminate inflorescence development was acropetal. When inflorescences developed to 5–8 cm, the microspore mother cells in the base florets of the inflorescences entered into meiosis prophase and the middle layer started to degrade. When inflorescences grew to 8–10 cm, the microspore mother cells in the based florets of the inflorescences were at the peak of meiosis and cytokinesis was synchronous. When bracts have opened to 15°, the microspore mother cells of the basal florets had undergone two divisions to form tetrads. When bracts have opened to 45°, the basal florets entered the mid-late uninucleate stage and the tapetum underwent degradation and autolysis. When bracts opened to >90°, mature pollen grains were 2-celled, with three germ pores and the middle layer tapetum completely degraded. Anther wall development followed the basic type, which was composed of an epidermal layer, an endothecial layer, middle layer (1–3 layers, fibrous thickening absent) and the tapetal layer (cell division was from uninucleate to an octonucleate cell). In summary, external morphology and gametophyte development in pecan staminate flowers were consistent to related; thus, the internal gamete development status can be determined from external morphological characteristics of the flower. This provided a sampling basis and theoretical foundation for in vitro culture of pollen grains and elucidation of flowering mechanisms.

description: Sixteen species of Solanaceae, belonging to five genera, were studied karyologically through chromosome counting, chromosomal measurement, and karyotype symmetry. Genome size (GS) estimation was performed on fifteen species using flow cytometry. The chromosome number 2n=24 was found in all Solanum species and Acnistus arborescens, 2n=22 was found in Brunfelsia uniflora, and 2n=16 in Cestrum representatives. Physalis pubescens was the only specie with evidence of polyploidy, showing 2n=4x=48 chromosomes. The chromosome numbers of S. adspersum, S. inodorum, S. flaccidum, S. sanctae-catharinae, and B. uniflora were reported for the first time. Haploid karyotype length (HKL) was statistically different between the studied species. The polyploid P. pubescens showed the largest HKL value, 93.10 µm. In general, karyotypes were symmetrical with predominance of metacentric chromosomes. Chromosome size was small in most species (<4 µm), while S. diploconos, C. laevigatum, and C. mariquitense, species with high HKL values, exhibited larger chromosomes. Genome size estimation were unpublished for ten studied species and were the first estimation for the genera Acnistus, Brunfelsia and Physalis. Were observed about eight-fold differences between species with averages varying from 2C=2.57 pg to 2C=20.27 pg. As both HKL and GS showed a continuous variation. We observed partial similarity in the species ordered according to HKL and GS. The Solanaceae genera showed a constant chromosome number and a tendency to posse symmetrical karyotypes. The genome size also showed differences, which suggests that chromosome evolution in the group could be driven by alterations in the repetitive fractions of the genome.

description: The karyotype and cytogenetic features of darkling beetle Accanthopus velikensis were analysed using conventional and differential staining. The diploid number was determined as 2n = 20 and the presence of Xyp sex determination system was observed with DAPI and silver staining as well as conventional staining. Although a single nucleolar material was observed in prophase I nuclei, multiple argyrophilic signals in diakinesis-metaphase I plates makes it difficult to determine the exact NOR location. Both conventionally and differentially stained plates showed that heterochromatin is mostly concentrated on centromeric regions of A. velikensis chromosomes. Obvious telomeric signals on some rod shaped bivalents as well as the X chromosome were also detected with AgNO3 and DAPI staining. Although presented karyotype of A. velikensis resemble to those of other Helopini members and follows the common patterns of Tenebrionid karyotypes, slight differences in chromosome morphologies, NORs and the heterochromatin distribution were detected. Our specimens also showed a unique haplotype for COI sequences with an 84-83% sequence similarity to database sequences for Tenebrionidae.

description: The present study evaluates the cytotoxic efficacy of methanolic extract of C. viminale on A. cepa root meristematic cells. DAPI staining was used to study the chromosomal aberrations indued by extract of C. viminale. Evans blue staining method was employed to estimate the cell death of root cells of A. cepa. The plant extract was found to impart severe cytological damges, specifically chromosomal aberrations at interphase and prophase stage of cell division. Various apoptotic signs such as apoptotic body formation, nuclear budding, micronucleus, nuclear disintegration, nuclear breakage etc. were observed in meristematic cells of A. cepa. The results suggest the cytotoxic, preferably genotoxic effect of methanolic extract of C. viminale as evidenced by various apoptotic symptoms on A. cepa root cells.

description: Synedrella nodiflora is a traditionally used medicinal plant. The aim of the present study was to analyze the clastogenic and cytotoxic effects (CCEs) of aerial parts’ aqueous extract of S. nodiflora (AAESN) on Wistar rat bone marrow cells (WRBMCs). The CCEs of AAESN were analyzed with light and fluorescence microscopes respectively. The data indicate a dose-dependent (100-500 mg/kg body weight [bw]) increase in the aberrant cell frequencies, chromosomal structural aberrations and a significant (p<0.001) increase in apoptosis in the AAESN treated WRBMCs. The chromosomal aberration per 100 cells (apoptosis %) were calculated as 2.01±0.241 (5.02±1.72), 4.76±0.05 (46.73±2.34), 5.37±0.32 (66.92±2.92) and 6.58±0.14 (76.79±0.73) respectively for the AAESN doses of 0, 100, 300 and 500 mg/kg bw. In conclusion, the AAESN may contain phytochemicals with clastogenic and cytotoxic efficacy on WRBMCs, indicating, having the anticancer as well as carcinogenic potentials. Therefore, it demands further an elaborate study to explore the active principle(s) and a proper care should be taken while it is prescribed in traditional medicine.

description: Altitude could greatly influence species distribution and even their genetic diversity. However, it is unclear how altitude has affected the genetic diversity and population structure of Rhododendron simsii Planch., an dominant forestry species in north temperate forest. In this research, 22 polymorphic EST-SSR markers were utilized to assess the genetic diversity of R. simsii population distributed at different altitudes of Wujiashan Mountain, a major peak of Dabie Mountains (central China). Totally, 203 alleles were obtained, and each locus gave out 5 to 19 alleles. High genetic diversity existed, as Nei’s gene diversity (h) and Shannon’s Information index (I) ranged from 0.728 to 0.920 and 1.430 to 2.690, with the mean value of 0.821 and 1.916, respectively. In particular, 11.1% of genetic differentiation was maintained between populations, while 88.9% occurred within populations. Moreover, moderate gene flow (2.001) among populations was observed, which could effectively resist genetic drift. The genetic diversity of all these five R. simsii populations varied significantly with elevation, basically showing high-low-high pattern with elevation increase. Without human intervention, genetic diversity of R. simsii populations might increase with the altitude. At the significance level (p < 0.05), negative correlation was found between genetic diversity and attenuation rate of light intensity (r=-0.873). Soil of Wujiashan Mountain was acid (the pH value ranged from 4.33 to 4.70), which was rich in organic matter, available phosphorus, available potassium, and alkali hydrolysable nitrogen, as these soil factors interacted with each other to affect the growth of R. simsii population. This research would contribute a lot to the knowledge of evolutionary history of R. simsii species and benefit subsequent management and conservation actions.
