    Full Text Available Abstract Background Past studies in the legume family (Fabaceae have uncovered several evolutionary trends including differential mutation and diversification rates across varying taxonomic levels. The legume tribe Psoraleeae is shown herein to exemplify these trends at the generic and species levels. This group includes a sizable diversification within North America dated at approximately 6.3 million years ago with skewed species distribution to the most recently derived genus, Pediomelum, suggesting a diversification rate shift. We estimate divergence dates of North American (NAm Psoraleeae using Bayesian MCMC sampling in BEAST based on eight DNA regions (ITS, waxy, matK, trnD-trnT, trnL-trnF, trnK, trnS-trnG, and rpoB-trnC. We also test the hypothesis of a diversification rate shift within NAm Psoraleeae using topological and temporal methods. We investigate the impact of climate change on diversification in this group by (1 testing the hypothesis that a shift from mesic to xeric habitats acted as a key innovation and (2 investigating diversification rate shifts along geologic time, discussing the impact of Quaternary climate oscillations on diversification. Results NAm Psoraleeae represents a recent, rapid radiation with several genera originating during the Pleistocene, 1 to 2 million years ago. A shift in diversification rate is supported by both methods with a 2.67-fold increase suggested around 2 million years ago followed by a 8.73-fold decrease 440,000 years ago. The hypothesis that a climate regime shift from mesic to xeric habitats drove increased diversification in affected taxa was not supported. Timing of the diversification rate increase supports the hypothesis that glaciation-induced climate changes during the Quaternary influenced diversification of the group. Nonrandom spatial diversification also exists, with greater species richness in the American Southwest. Conclusion This study outlines NAm Psoraleeae as a model example

    Full Text Available According to Sushruta, no plant in this world is useless. A large number of crude drugs used in Ayurvedic system employ plants of family Fabaceae. The family Fabaceae popularly known as legumes, is the third largest order of seed-plants containing about 600 genera with 12,000 speices. All the three subfamilies of Fabaceae have been given the status of family and hence they will be treated here as distinct families. Details of medicinal plants of these families and their uses are presented here.

    Full Text Available Fabaceae species play a key role in ecosystem functioning through their capacity to fix atmospheric nitrogen via their symbiosis with Rhizobium bacteria. To increase benefits of using Fabaceae in agricultural systems, it is necessary to find ways to evaluate species or genotypes having potential adaptations to sub-optimal growth conditions. We evaluated the relevance of phylogenetic distance, absolute trait distance and hierarchical trait distance for comparing the adaptation of 13 grassland Fabaceae species to different habitats, i.e. ecological niches. We measured a wide range of functional traits (root traits, leaf traits and whole plant traits in these species. Species phylogenetic and ecological distances were assessed from a species-level phylogenetic tree and species’ ecological indicator values, respectively. We demonstrated that differences in ecological niches between grassland Fabaceae species were related more to their hierarchical trait distances than to their phylogenetic distances. We showed that grassland Fabaceae functional traits tend to converge among species with the same ecological requirements. Species with acquisitive root strategies (thin roots, shallow root systems are competitive species adapted to non-stressful meadows, while conservative ones (coarse roots, deep root systems are able to tolerate stressful continental climates. In contrast, acquisitive species appeared to be able to tolerate low soil-P availability, while conservative ones need high P availability. Finally we highlight that traits converge along the ecological gradient, providing the assumption that species with similar root-trait values are better able to coexist, regardless of their phylogenetic distance.

    Full Text Available The aim of this study was to investigate the reproductive biology of Bowdichia virgilioides in an area of Cerrado (Brazilian Savanna. The study was carried out in Chapadinha, State of Maranhão in northeastern Brazil. Bowdichia virgilioides has cornucopia flowering and annual pattern. Flowering occurred at the beginning of the dry season, between June and August; and fruiting in the middle of this season, between July and October. The anthesis of B. virgilioides is diurnal, and the main flower resource is the nectar. During the flower opening, the anthers becomes dehiscent and thus pollen grains are deposited at the stigma, promoting automatic selfpollination. The species is self-compatible and apomitic. In the study area, they were visited by nine species of bees, four butterflies, two wasps, and two hummingbirds. The visits began in early morning and persisted throughout the day, with a peak of activity between 8:00 and 9:00hours. Species of Centris were the main visitors of B. virgilioides. The butterfly and wasp species were considered resource robbers, and other floral visitors were considered occasional visitors. Although the flowers of B. virgilioides are widely visited, the species shows a high rate of inbreeding because of automatic self-pollination.Este trabalho teve como objetivo estudar a biologia reprodutiva de Bowdichia virgilioides Kunth (Fabaceae e avaliar o papel dos visitantes florais em seu sucesso reprodutivo. Bowdichia virgilioides apresenta padrão de floração anual e do tipo cornucópica. A floração ocorre no início da estação seca, entre os meses de junho e agosto e a frutificação no meio desta estação, entre os meses de julho e outubro. Suas flores são de antese diurna e apresentam néctar como recurso floral. Durante a abertura floral, as anteras se encontram deiscentes e por esta razão há a adesão dos grãos de pólen no estigma da própria flor, promovendo o processo de autopolinização passiva. A esp

  12. Molecular systematics of selected genera of subfamily mimosoidae-fabaceae

    International Nuclear Information System (INIS)

    Family Mimosoidae-Fabaceae is of economic importance to local communities for its medicinal usage. It has commercial value, but the parts sold in the market are difficult to identify on the basis of morphological characters and therefore needs molecular systematics approaches. Hence, the utility of potential DNA barcodes for selected Acacia and Albizia species by using three cpDNA regions rbcL, matK and trnH-psbA was tested in this study. Our study suggests that the rbcL region can be used to identify these species and discriminate among them more effectively than matK and trnH-psbA. The latter regions proved to be less successful in sequencing particularly trnH-psbA. Therefore, rbcL is an improved and efficient tool for species identification of these medicinal plants and may be recommended for a broad series of subfamily Mimosoideae (Family: Fabaceae) plants, making it a potential DNA barcode for these taxa. Sequence data obtained from rbcL and matK also indicated that Acacia and Albizia are polyphyletic. The phylogenetic analysis on the basis of rbcL proved that Acacia nilotica and Acacia nilotica ssp. hemispherica are closely related as they form the sister groups. (author)

    In this study, we tested the applicability of the core DNA barcode MATK for identifying species within the Fabaceae family. Based on an evaluation of genetic variation, DNA barcoding gaps, and species discrimination power, MATK is a useful barcode for Fabaceae species. Of 1355 plant samples collected from 1079 species belonging to 409 diverse genera, MATK precisely identified approximately 80 % and 96 % of them at the species and genus levels, respectively. Therefore, our research indicates that the MATK region is a valuable marker for plant species within Fabaceae. PMID:20549596

    Full Text Available With at least 60% of the Millettia species (Fabaceae being in medicinal use, we found it relevant to assess the potential antiprotozoal and antifungal activities of Millettia richardiana. Water and methanol crude extracts of the stem barks from M. richardiana and the six fractions resulting from the fractionation of the methanol extract were tested. The dichloromethane extracted fraction showed the best in vitro antiprotozoal activities (IC50 = 5.8 μg/mL against Plasmodium falciparum, 11.8 μg/mL against Leishmania donovani and 12.8 μg/mL against Trypanosoma brucei brucei as well as low cytotoxicity on several cell lines. The phytochemical analysis showed this selected fraction to be rich in terpenoids and alkaloids, which could explain its antiparasitic activity. A phytochemical study revealed the presence of lonchocarpenin, betulinic acid, β-amyrin, lupeol, palmitic acid, linoleic acid and stearic acid, among which betulinic acid and lupeol could be the compounds responsible of these antiprotozoal activities. By contrast, neither the crude extracts nor the fractions showed antifungal activity against Candida. These results confirm the importance of the genus Millettia in Malagasy ethnomedicine, its potential use in antiparasitic therapy, and the interest of developing a sustainable exploitation of this plant. Moreover, both molecules betulinic acid and lupeol appeared as very relevant molecules for their antiprotozoal properties.

    Objective: To carry out a pharmacobotanical study of Lonchocarpus cyanescens (Schum & Thonn) Benth (L. cyanescens) and Leptoderris micrantha Dunn (L. micrantha) which are two key medicinal plants from the family Fabaceae.Methods:The epidermal peel was obtained by soaking the leaf in concentrated nitric acid (HNO3) in a petri dish. Both surfaces were carefully mounted on clean glass slides and dehydrated by ethyl alcohol, and stained with safaranin O for 2 min. Transverse sections of plant leaf were obtained by free hand sectioning. Phytochemical screening for various constituents was carried out on the powdered leaves. Other parameters such as, moisture content, ash value, acid insoluble ash, water-soluble ash, water and alcohol extractive values were obtained by standard techniques.Results:The distinctive features of the species include: the presence of stomata on both surfaces of L. cyanescens and the absence in L. micrantha. Presence of larger epidermal cells in both upper and lower surfaces of L. cyanescens [(35.25±1.64)í(31.25±2.36), (43.0±2.63)í(39.5±5.11)] respectively compared to L. micrantha. Glandular multicellular trichomes are present in L. micrantha but absent in L. cyanescens. Numerous trichomes surround the transverse section of the leaf of L.micrantha but absent in L. cyanescens. Preliminary phytochemical screening showed that both species contain secondary metabolites such as alkaloids, anthraquinones, cardiac glycosides, tannins, saponins, steroids and flavonoids.Conclusions:The microscopic and phytochemical data provided in this study are useful for the standardization of the medicinal plants.

    In this study, pollen viability and germination of three plant species, Cercis siliquastrum L., Robinia pseudoacacia L., and Spartium junceum L., belonging to the Fabaceae family, was evaluated in sites with different intensity of road traffic, constantly monitored with continuous analysers for air pollutants (carbon monoxide (CO), sulphur dioxide (SO(2)), and nitrogen dioxide (NO(2))) by the Municipality of Catania. Two sites, in which road traffic was absent, were selected, too. The percentages of viable pollen by 2,3,5-trypheniltetrazolium chloride (TTC) test ranged from 59.0 to 90.2 % in C. siliquastrum, from 61.5 to 83.5 % in S. junceum and from 67.5 to 84.3 % in R. pseudoacacia. The percentages of germination varied from 41.0 to 72.7 % in C. siliquastrum, from 42.0 to 64.7 % in S. junceum and from 38.3 to 66.3 % in R. pseudoacacia. The highest percentages of viable pollens were found in no-road traffic stations by either TTC or germination tests, while the lowest values were detected in a site characterised by heavy road traffic. In the monitored period (2007-2009), pollen viability, germinability and tube length of C. siliquastrum resulted in a significant negative correlation to CO, SO(2) and NO(2), whereas data from TTC and germination tests on S. junceum and R. pseudoacacia pollens were not well correlated to air pollutants. The results showed that pollen viability, germination and tube growth in C. siliquastrum were affected by air pollution. S. junceum and R. pseudoacacia were not very influenced by air pollutants, suggesting a different pollen sensitivity of these species.

The major obstacles in aDNA studies are mutations, contamination and fragmentation. Its studies may be crucial for crop history if integrated with human aDNA research and historical linguistics, both general and relating to agriculture. Legumes (Fabaceae are one of the richest end economically most important plant families, not only from Neolithic onwards, since they were used as food by Neanderthals and Paleolithic modern man. The idea of extracting and analysing legume aDNA was considered beneficial for both basic science and applied research, with an emphasis on genetic resources and plant breeding. The first reported successful and attested extraction of the legume aDNA was done from the sample of charred seeds of pea (Pisum sativum and bitter vetch (Vicia ervilia from Hissar, southeast Serbia, dated to 1,350 - 1,000 Before Christ.

A comparative analysis of four informative chloroplast DNA regions (trnSG, trnK, matK and rbcL among the modern wild and cultivated pea taxa demonstrated not only that the extracted aDNA was genuine, on the basis of mutation rate, but also that the ancient Hissar pea was most likely an early domesticated crop, related to the modern wild pea of a neighbouring region. It is anticipated that this premier extraction of legume aDNA may provide taxonomists with the answers to diverse questions, such as leaf development in legumes, as well as with novel data on the single steps in domesticating legume crops worldwide.

    Full Text Available Peltophorum africanum (Fabaceae is a deciduous tree widespread in southern Africa. The plant has many ethnomedical and ethnoveterinary uses. Root and bark decoctions are used to treat diarrhoea, dysentery, sore throat, wounds, back and joint pains, HIV-AIDS, venereal diseases and infertility. Pastoralists and rural farmers use the root and bark extracts to treat diarrhoea, dysentery, infertility, and to promote well-being and resistance to diseases in cattle. To evaluate these ethnobotanical leads, dried leaves, stem bark and root bark were extracted with ethanol, acetone, dichloromethane and hexane. Polyphenols in the extract were determined by the Folin-Ciocalteu method with gallic acid as standard. Qualitative antioxidant activity was screened by spraying thin layer chromatograms (TLC of the extracts with 0.2 % 1, 1-diphenyl-2-picryl hydrazyl (DPPH, and quantified with Trolox equivalent antioxidant capacity (TEAC assay. Minimum inhibitory concentration (MIC and total antibacterial activity (TAA were determined by serial microplate dilution for Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Enterococcus faecalis, with gentamicin as standard and tetrazolium violet as growth indicator. Acetone and ethanol extracted the largest quantity of material. Polyphenols concentration was 49.2% in acetone extract of the root and 3.8 % in dichloromethane extract of the leaf. Antioxidant activity of at least 5 antioxidant compounds as measured by TEAC ranged from 1.34 (ethanol extract of the root to 0.01 (hexane extract of the leaf. The total antibacterial activity (volume to which active compounds present in 1 g plant material can be diluted and still inhibit bacterial growth was 1263 mℓ/g for ethanol extract of the root against S. aureus, and 800 mℓ/g for acetone extract of the root against P. aeruginosa. There was substantial activity against both Gram-positive and Gram-negative bacteria, with MIC values of 0.08 mg/mℓ for S

    It is accepted that the papilionaceous corolla of the Fabaceae evolved under the selective pressure of bee pollinators. Morphology and function of different parts of Coronilla emerus L. flowers were related to their role in the pollination mechanism. The corolla has a vexillum with red nectar lines, a keel hiding stamens and pistil, and two wing petals fasten to the keel with two notched folds. Pollinators land on the complex of keel and wings, trigger the protrusion of pollen and finally of ...

    Full Text Available Historical usage of the roots of the legume Tephrosia virginiana as a piscicide by Native Americans has been documented. Due to questions about geographic variation in toxicity, an examination of the toxicity of six Oklahoma populations of the species was conducted. Rootstock extracts of plants in all populations exhibited acute toxicity in a standard laboratory bioassay using larval fathead minnows (Pimephales promelas. Isolation and identification of the compound or compounds responsible were not undertaken, however, toxicity is generally thought to be due to the presence of rotenone and related compounds. Although considerable variation in LC50 values exists among the six populations, this study produced few statistically significant differences. Correlations between plant toxicity and edaphic factors were not seen.

    2015-06-01

    Full Text Available This study was undertaken at the Botanical Garden of Biological Sciences Department, Kogi State University, Anyigba with the aim of assessing the systematic and phylogenetic relevance of leaf epidermal attributes in the 10 selected species of Fabaceae. Stomata, trichomes and epidermal cell attributes were taken from adaxial and abaxial leaf surfaces. Results obtained in this study revealed that all the 10 plant species considered possess hypo-amphistomatic leaf condition, paracytic stomata type, polygon and irregular shape epidermal cells(on the abaxial surface which points to their common ancestry. All the analyzed leaf epidermal traits considered on the adaxial and abaxial surfaces showed significant variations among the 10 studied plant species which indicates that genetic diversity exists among members of Fabaceae for their delimitation. It was also observed that all the plants with tree habit considered in this study (i.e Delonix regia, Parkia biglobosa, Senna siamea, Daniella oliveri and Caesalpinia pulcherrima lack stomata on the adaxial surfaces which strongly suggest that absence of stomata on the adaxial surface may be peculiar to Legumes with such habit. Cluster analysis revealed 2 major clusters and 2 sub-clusters with the first cluster comprising only Senna siamea and Caesalpinia pulcherrima which confirms their close phylogenetic relationship. Variations in trichomes, stomata and epidermal attributes were obvious and could be used to resolve systematic and phylogenetic problems in this family.

    Nineteen plants from Fabaceae family, which were used in Thai traditional medicine for treatment of diabetes, were determined of α-glucosidase inhibitory activity via enzymatic reaction. In this reaction, α-glucosidase was used as enzyme, which, reacted with the substrate, p-nitrophenol-D-glucopyranoside (pNPG). After that the product, p-nitro phenol (pNP) will be occurred and observed the yellow colour at 405 nm. In this study, acarbose was used as positive standard which, inhibited this enzyme with IC₅₀ as 331 ± 4.73 μg/ml. Caesalpinia pulcherrima leaves showed the highest activity with IC₅₀ as 436.97 ± 9.44 μg/ml. Furthermore, Bauhinia malabarica leaves presented moderately activity with IC₅₀ as 745.08 ± 11.15 μg/ml. However, the other plants showed mild to none activity of α-glucosidase inhibition. Accordingly, this study can support anti-diabetes of these plants in traditional medicine and it will be the database of the biological activity of Fabaceae plant. PMID:26408887

    2016-07-01

    Chlorinated auxin (4-chloroindole-3-acetic acid, 4-Cl-IAA), a highly potent plant hormone, was once thought to be restricted to species of the tribe Fabeae within the Fabaceae, until we recently detected this hormone in the seeds of Medicago, Melilotus and Trifolium species. The absence of 4-Cl-IAA in the seeds of the cultivated species Cicer aeritinum from the Cicerae tribe, immediately basal to the Fabeae and Trifolieae tribes, suggested a single evolutionary origin of 4-Cl-IAA. Here, we provide a more robust phylogenetic placement of the ability to produce chlorinated auxin by screening key species spanning this evolutionary transition. We report no detectable level of 4-Cl-IAA in Cicer echinospermum (a wild relative of C. aeritinum) and 4 species (Galega officinalis, Parochetus communis, Astragalus propinquus and A. sinicus) from tribes or clades more basal or sister to the Cicerae tribe. We did detect 4-Cl-IAA in the dry seeds of 4 species from the genus Ononis that are either basal to the genera Medicago, Melilotus and Trigonella or basal to, but still within, the Fabeae and Trifolieae (ex. Parochetus) clades. We conclude that the single evolutionary origin of this hormone in seeds can be used as a phylogenetically informative trait within the Fabaceae. PMID:27302610

    Full Text Available Abstract Background Accurate computational identification of cis-regulatory motifs is difficult, particularly in eukaryotic promoters, which typically contain multiple short and degenerate DNA sequences bound by several interacting factors. Enrichment in combinations of rare motifs in the promoter sequence of functionally or evolutionarily related genes among several species is an indicator of conserved transcriptional regulatory mechanisms. This provides a basis for the computational identification of cis-regulatory motifs. Results We have used a discriminative seeding DNA motif discovery algorithm for an in-depth analysis of 54 seed storage protein (SSP gene promoters from three plant families, namely Brassicaceae (mustards, Fabaceae (legumes and Poaceae (grasses using backgrounds based on complete sets of promoters from a representative species in each family, namely Arabidopsis (Arabidopsis thaliana (L. Heynh., soybean (Glycine max (L. Merr. and rice (Oryza sativa L. respectively. We have identified three conserved motifs (two RY-like and one ACGT-like in Brassicaceae and Fabaceae SSP gene promoters that are similar to experimentally characterized seed-specific cis-regulatory elements. Fabaceae SSP gene promoter sequences are also enriched in a novel, seed-specific E2Fb-like motif. Conserved motifs identified in Poaceae SSP gene promoters include a GCN4-like motif, two prolamin-box-like motifs and an Skn-1-like motif. Evidence of the presence of a variant of the TATA-box is found in the SSP gene promoters from the three plant families. Motifs discovered in SSP gene promoters were used to score whole-genome sets of promoters from Arabidopsis, soybean and rice. The highest-scoring promoters are associated with genes coding for different subunits or precursors of seed storage proteins. Conclusion Seed storage protein gene promoter motifs are conserved in diverse species, and different plant families are characterized by a distinct combination

    The occurrence of Scotch broom Cytisus scoparius (L.) Link (Fabaceae), is reported for the first time in Brazil. The species has been registered in the species-rich Campos Sulinos grasslands, in the Campos de Cima da Serra, and in the Serra do Sudeste. Naturalizing populations were frequently formed in natural habitats near to human settlements, where prevailing land uses and disturbances facilitate dispersal and establishment. The plant is an invasive species that has globally caused significant damage to biodiversity and economic losses. In Brazil, the species has a strong potential for spreading into a wide range of ecosystems. The Atlantic Forest biome and part of the Pampa biome, together known as the Campos Sulinos, represent optimal areas for the species. Features of the observed populations and recommendations for management are presented. PMID:26871495

    Full Text Available ABSTRACTWe studied the effects of seed storage on germination and dormancy alleviation in three species of Fabaceae endemic to campo rupestrein southeastern Brazil. Fresh seeds of Collaea cipoensis, Mimosa maguirei and Mimosa foliolosawere set to germinate and germination of seeds after four, five and 13 years of storage was tested. Seed viability was maintained for all species after the full storage period. Seed storage significantly increased germination percentage and decreased germination time for C. cipoensisand M. foliolosa, suggesting the alleviation of physical dormancy with storage. However, we did not find evidence of dormancy alleviation in M. maguirei since stored seeds showed a decrease in germination in comparison to that of fresh seeds. Our data indicate species-specific storage-mediated dormancy alleviation, which will have important implications for restoration of campo rupestre.

  2. Evidence That Chlorinated Auxin Is Restricted to the Fabaceae But Not to the Fabeae.

    Auxin is a pivotal plant hormone, usually occurring in the form of indole-3-acetic acid (IAA). However, in maturing pea (Pisum sativum) seeds, the level of the chlorinated auxin, 4-chloroindole-3-acetic acid (4-Cl-IAA), greatly exceeds that of IAA. A key issue is how plants produce halogenated compounds such as 4-Cl-IAA. To better understand this topic, we investigated the distribution of the chlorinated auxin. We show for the first time, to our knowledge, that 4-Cl-IAA is found in the seeds of Medicago truncatula, Melilotus indicus, and three species of Trifolium. Furthermore, we found no evidence that Pinus spp. synthesize 4-Cl-IAA in seeds, contrary to a previous report. The evidence indicates a single evolutionary origin of 4-Cl-IAA synthesis in the Fabaceae, which may provide an ideal model system to further investigate the action and activity of halogenating enzymes in plants.

    Full Text Available Fabaceae is of great ethnobotanical importance in indigenous and urban communities throughout the world. This work presents a revision of the use of Fabaceae as a food and/or medicinal resource in Argentine-Chilean Patagonia. It is based on a bibliographical analysis of 27 ethnobotanical sources and catalogues of regional flora. Approximately 234 wild species grow in Patagonia, mainly (60% in arid environments, whilst the remainder belong to Sub-Antarctic forest. It was found that 12.8% (30 species, mainly woody, conspicuous plants, are collected for food or medicines. Most of the species used grow in arid environments. Cultivation and purchase/barter enrich the Fabaceae offer, bringing it up to a total of 63 species. The richness of native and exotic species, and the existence of multiple strategies for obtaining these plants, indicates hybridization of knowledge and practices. Only 22% of the total species used are mentioned in bothcontexts of food and medicine, reflecting low-use complementation. This study suggests a significant ecological appearance and a high level of availability in shops and exchange networks in Patagonia, highlighting the need to consider the full set of environmental and socioeconomic factors in research related to the use and cultural importance of plants in regional contexts.

    To increase the understanding of the ethnopharmacology of a single species, elaboration of dispersed primary data is required. Tamarindus indica L. (Fabaceae), or tamarind, is a common tree, especially in West Africa, with a good potential to contribute to affordable local health care based on traditional medicine (TM). For this single species review, more than 60 references with detailed information on the ethnopharmacology of Tamarindus indica in the African context were selected. It showed that most prominently, the fruits are used as laxative or febrifuge throughout the Sahel and Soudan ecological zones. Tamarind bark and leaves are often involved in the treatment of wounds, especially in central West Africa. While the bark is used to treat diarrhoea in West Africa, the leaves are used for this purpose in East Africa. Our findings suggest a difference in the way tamarind is used between East and West Africa and we assess the similarities of its uses within those regions. This review demonstrates the capability of literature research to reveal knowledge by mining and compiling information from the growing body of primary ethnopharmacologic data, much of which is published in this journal. By creating a specific profile of tamarind in the context of traditional medicine throughout Africa, the authors contribute to the collection of current ethnobotanic species accounts on Tamarindus indica that tend to be qualitative and more general.

    Full Text Available Glycyrrhiza glabra L. (Licorice, belongs to the Fabaceae family. The species is included in the Crop Wild relatives list for Bulgaria and is close to beans and peas. Its origin is Southeast Europe, the Mediterranean and Asia, where Bulgaria falls. The roots of the plant contain glycyrrhizin, 30 to 50 times sweetener than the sucrose. As a CWR, as well as due to the high level of glycyrrhizin in the roots, the conservation and maintenance of the species is of interest, although it is not included in the list of threatened plant species yet. In the Institute of Plant Genetic Resources - Sadovo Glycyrrhiza glabra is maintained in situ in the Botanical garden. Besides the in situ conservation of the species, in vitro techniques are a reliable means of reproduction and long-term storage. After introduction of the raw cuttings from plant species in culture in vitro, the process of micropropagation is accomplished by single bud microcuttings in nutrient medium fitted with growth regulators, enabling the development of single-rooted stems with options of repeatedly subcultivating. Along with that the possibility for long term in vitro propagation by reduction of the composition of the nutrient medium was tested, where the period for conservation of the cultivated explants reaches 8 months.

    Tibetia and Gueldenstaedtia are two morphologically similar and small genera in Fabaceae, with distributions largely corresponding to the Sino-Himalayan and Sino-Japanese subkingdoms in eastern Asia, respectively. These two genera have confusing relationships based on morphology; therefore, we aimed to provide a clear understanding of their phylogenetic and biogeographic evolution within eastern Asia. In our investigations we included 88 samples representing five Gueldenstaedtia species, five Tibetia species, and outgroup species were sequenced using five markers (nuclear: ITS; chloroplast: matK, trnL-F, psbA-trnH and rbcL). Our phylogenetic results support (1) the monophyly of Tibetia and of Gueldenstaedtia, respectively; and (2) that Tibetia and Gueldenstaedtia are sister genera. Additionally, our data identified that Tibetia species had much higher sequence variation than Gueldenstaedtia species. Our results suggest that the two genera were separated from each other about 17.23 million years ago, which is congruent with the Himalayan orogeny and the uplift of the Tibetan Plateau in the mid Miocene. The divergence of Tibetia and Gueldenstaedtia is strongly supported by the separation of the Sino-Himalayan and Sino-Japanese region within eastern Asia. In addition, the habitat heterogeneity may accelerate the molecular divergence of Tibetia in the Sino-Himalayan region. PMID:27632535

  13. Morphofunctional Traits and Pollination Mechanisms of Coronilla emerus L. Flowers (Fabaceae

    Full Text Available It is accepted that the papilionaceous corolla of the Fabaceae evolved under the selective pressure of bee pollinators. Morphology and function of different parts of Coronilla emerus L. flowers were related to their role in the pollination mechanism. The corolla has a vexillum with red nectar lines, a keel hiding stamens and pistil, and two wing petals fasten to the keel with two notched folds. Pollinators land on the complex of keel and wings, trigger the protrusion of pollen and finally of the stigma from the keel tip. Data on pollen viability and stigma receptivity prove that flowers are proterandrous. The results of hand-pollination experiments confirmed that insects are fundamental to set seed. Interaction with pollinators allows not only the transport of pollen but also the rupture of the stigmatic cuticle, necessary to achieve both allogamy and autogamy. Field observations showed that Hymenoptera, Lepidoptera, and Diptera visited the flowers. Only some of the Hymenoptera landed on the flowers from the front and elicited pollination mechanisms. Most of the insects sucked the nectar from the back without any pollen transfer. Finally, morphological and functional characteristics of C. emerus flowers are discussed in terms of floral larceny and reduction in pollination efficiency.

    Full Text Available It is known that the efficient dispersal is one among other features that amplify the invasion potential of a plant. Knowledge of the ontogeny, morphology and fruit dispersal of species is indispensable for weed control in crops. To identify the pericarp structures involved in the fragmentation and dehiscence processes and other features related to dispersal, we studied the pericarp development of Aeschynomene evenia Wright, Desmodium incanum (Sw. DC. and Vigna luteola (Jacq. Benth. (Fabaceae-Faboideae, all of which are considered weeds in certain situations. For light and scanning electron microscopy studies, we fixed and processed buds, flowers and fruits, according to usual methods, at different stages of development. We observed that the sclerenchymatous endocarp is essential for dehiscence in legumes, as well as for fragmentation in loments. We also found that the presence of hook-shaped trichomes, sclereid nests in the mesocarp, septum, hypodermis and the formation of false septa are essential to the diaspore dispersal of the species studied.

    Full Text Available The Acacia genus has presented various secondary metabolites, such as tannins, flavonoids, alkaloids and gums. Preparations from different species have been applied for diabetes, gastrointestinal disorders and inflammatory diseases in the traditional medicine and have demonstrated cytotoxic, antimicrobial and antiparasitic activities. Acacia podalyriifolia A. Cunn. ex G. Don (Fabaceae is a small wood, indigenous to Australia and cultivated worldwide for its ornamental feature. This work aimed to characterize the anatomy of the phyllode and stem, in order to contribute to the species identification. The botanical material was fixed, sectioned and prepared according to usual light and scanning microtechniques. The epidermal cells, in surface view, are polygonal and coated with striate and thick cuticle, and filaments of epicuticular wax. Paracytic stomata and unicellular non-glandular trichomes are seen. Palisade and ground parenchymas, and minor collateral bundles with xylem directed alternately to upper and lower sides occur in the blade. The midrib shows two collateral bundles facing each other. The stem, in incipient secondary growth, exhibits epidermis, annular collenchyma, sclerenchymatic sheath and collateral vascular organization. Cells containing phenolic compounds and prisms of calcium oxalate are observed.

    Melanoxylon brauna (Fabaceae - Caesalpinioideae) is an endemic and valuable hardwood tree species in the Brazilian Atlantic rainforest; it is comparable to African ebony wood. We tested three protocols of DNA extraction based on the citrimonium bromide (CTAB) method and evaluated the quantity, purity and integrity of the DNA. We also determined whether these procedures interfere with PCR amplification in order to develop a protocol for M. brauna. We found that the quality and integrity of DNA were improved with the use of proteinase K in the extraction buffer and by modifications in the centrifugation speed. The lowest concentration of DNA was obtained with Doyle and Doyle's protocol (5.42 ng/μL). Ferreira and Grattapaglia's protocol modified for M. brauna provided the most DNA (36.89 ng/μL) and the highest quality DNA (purity ratio of 1.80 nm). The original Ferreira and Grattapaglia protocol provided 13.42 ng/μL DNA; however, the purity ratio (1.44 nm) indicates protein contamination. PCR results showed that Ferreira and Grattapaglia's protocol modified for M. brauna gave satisfactory quantity and purity of DNA for molecular studies.

    Full Text Available Ethnobotany is a multidisciplinary science defined as the interaction between plants and people. On the basis of ethnomedicinal use, antipyretic activity of petroleum ether, ethyl acetate, chloroform, methanol extract of Cassia fistula Linn (Fabaceae bark has been investigated in albino rats. Normal body temperature is regulated by a centre in the hypothalamus that ensures a balance between heat loss and production. Fever occurs when there is a disturbance of this hypothalamic ‘thermostat’, which leads to the set-point of body temperature being raised. Once there has been a return to the normal set-point, temperature regulating mechanism (dilatation of superficial blood vessels, sweating etc. operates to reduce temperature. The study was carried out by using dose of 300 mg/kg orally. Experimental results exhibited that petroleum ether, ethyl acetate, chloroform, methanol extract of Cassia fistula bark, possess a significant antipyretic effect. After inducing 15% w/v suspension of yeast (1ml /100gm Body weight, temperature of experimental animal was increased. Then different extracts of the drug was induced into albino rats, which shows significant results. It was observed that methanol extract at a dose of 300 mg / kg body weight showed maximum antipyretic activity amongst other extracts which is statistically significant as the value of p<0.05.

    Cyclotides are plant proteins whose defining structural features are a head-to-tail cyclized backbone and three interlocking disulfide bonds, which in combination are known as a cyclic cystine knot. This unique structural motif confers cyclotides with exceptional resistance to proteolysis. Their endogenous function is thought to be as plant defense agents, associated with their insecticidal and larval growth-inhibitory properties. However, in addition, an array of pharmaceutically relevant biological activities has been ascribed to cyclotides, including anti-HIV, anthelmintic, uterotonic, and antimicrobial effects. So far, >150 cyclotides have been elucidated from members of the Rubiaceae, Violaceae, and Cucurbitaceae plant families, but their wider distribution among other plant families remains unclear. Clitoria ternatea (Butterfly pea) is a member of plant family Fabaceae and through its usage in traditional medicine to aid childbirth bears similarity to Oldenlandia affinis, from which many cyclotides have been isolated. Using a combination of nanospray and matrix-assisted laser desorption ionization-time-of-flight (MALDI-TOF) analyses, we examined seed extracts of C. ternatea and discovered cyclotides in the Fabaceae, the third-largest family of flowering plants. We characterized 12 novel cyclotides, thus expanding knowledge of cyclotide distribution and evolution within the plant kingdom. The discovery of cyclotides containing novel sequence motifs near the in planta cyclization site has provided new insights into cyclotide biosynthesis. In particular, MS analyses of the novel cyclotides from C. ternatea suggest that Asn to Asp variants at the cyclization site are more common than previously recognized. Moreover, this study provides impetus for the examination of other economically and agriculturally significant species within Fabaceae, now the largest plant family from which cyclotides have been described.

    Arsenic (As) is a toxic element to most organisms. Studies investigating anatomic alterations due to As exposure in plants are scarce but of utmost importance to the establishment of environmental biomonitoring techniques. So, this study aimed to investigate the effects of As on the development and initial root growth in Cajanus cajan (Fabaceae), characterize and quantify the possible damages, evaluate genotoxic effects, and identify structural markers to be used in environmental bioindication. Plants were exposed hydroponically to 0.5, 1.0, 1.5, and 2.0 mg As L(-1), as sodium arsenate. Growth parameters were measured, and in the end of the exposure, root samples were analyzed for qualitative and quantitative anatomical alterations. Arsenic genotoxicity was evaluated through analysis of the mitotic index in the root apex. Compared to the control, As-treated seedlings showed an altered architecture, with significantly decreased root length (due to the lower mitotic index in the apical meristem and reduced elongation of parenchyma cells) with darkened color, and abnormal development of the root cap. A significant increase in vascular cylinder/root diameter ratio was also detected, due to the reduction of the cellular spaces in the cortex. The secondary xylem vessel elements were reduced in diameter and had sinuous walls. The severest damage was visible in the ramification zone, where uncommon division planes of phellogen and cambium cells and disintegration of the parenchyma cells adjacent to lateral roots were observed. The high sensibility of C. cajan to As was confirmed, since it caused severe damages in root growth and anatomy. The main structural markers for As toxicity were the altered root architecture, with the reduction of the elongation zone and increase of ramification zone length, and the root primordia retained within the cortex. Our results show a new approach about As toxicity and indicate that C. cajan is a promising species to be used for

    Bourland, N.

    2012-01-01

    Full Text Available Pericopsis elata (Fabaceae is a valuable timber species occurring in moist semi-deciduous African forests. While it is at present substantially reduced, the tree's natural distribution previously covered several distinct areas from Côte d'Ivoire to the Democratic Republic of Congo. This species has been logged since the second half of the 20th century. Because it suffers from a lack of regeneration, P. elata is now included in CITES Appendix II and is recorded as "Endangered A1cd" on the IUCN Red List. As with other long-lived light-demanding species, the survival of P. elata may have been favored by important disturbances that occurred in the Congo Basin during the last millennia. While both international trade and industrial uses of the wood of P. elata are well documented, information about its ecology are very sparse or contradictory, and even absent in some cases (e.g., regarding its effective flowering diameter. Furthermore, data describing the management of P. elata are scarce, including potential solutions to compensate for the deficit of natural regeneration. Along the same lines, genetic studies still remain at an early stage and only vague hypotheses have been offered to explain the origins of the tree's populations. We emphasize the need for new research on those topics. Further studies would be useful in deciding whether P. elata populations can continue to be logged without the species being threatened with extinction. Finally, such research needs to target effective and inexpensive management procedures that could secure the future of the species in a logging context.

    Full Text Available Stryphnodendron adstringens (Mart. Coville (barbatimão is a tree belonging to the Fabaceae family, and it is commonly found in the southeastern Brazilian cerrado. The stem bark of this tree is traditionally used as an anti-inflammatory and antiseptic agent to treat leucorrhea and diarrhea, as well as to promote wound healing (owing to the presence of proanthocyanidins. Proanthocyanidins were obtained from the ethanolic extract of S. adstringens stem bark and assessed by reversed phase-high performance liquid chromatography with an ultraviolet/diode array detector. The identified compounds included gallic acid, catechin, gallocatechin (GC, epigallocatechin, and epigallocatechin gallate (EGCG. The selected markers, GC and EGCG, were simultaneously used for chromatographic validation (linearity range: 30-330 ng, equivalent to 3-33 µg/mL; r>0.998. The method showed precision (intra-day relative standard deviation [RSD]: 1.72% for GC; 1.16% for EGCG; inter-day RSD: 1.74%-2.60% for both markers, accuracy, robustness, and selectivity. The limits of detection and quantitation were 0.29 µg/ml and 0.89 µg/ml for GC, and 0.88 µg/mL and 2.67 µg/mL for EGCG, respectively. In addition, S. obovatum was evaluated and showed an average of 12.2 µg/mL for GC (equivalent to 1.22% w/w and 14.2 µg/mL for EGCG (equivalent to 1.42% w/w in the ethanolic extract. The quantitative results were compared to those obtained for S. adstringens, which showed that the markers are present in both species.

    2000-12-01

    Because of some catastrophic events which occurred in Mexico during the 1980 decade, the utilization of "tepescohuite" bark against skin wounds and burns was popularized. The media manipulated the lack of available information about its medical properties and gave erroneous information to the society propagating a lot of myths. Therefore, the aim of this paper is to determine its taxonomic identity and to study the distribution, bark and wood anatomy of this species, and to determine its actual and historic uses, and the compilation of the information about bark pharmacology and toxicity. Its taxonomic identity is established as Mimosa tenuiflora (Willd.) Poir. (Fabaceae-Mimosoideae). It blooms and fructifies from November to June, occurring in Mexico (the states of Oaxaca and Chiapas), Guatemala, Honduras, El Salvador, Nicaragua, Panama, Colombia, Venezuela and Brazil, at altitudes of 0-1110 (-1520) m. In Mexico, it is found in dry forests, thorny thickets, Pinus and Pinus-Quercus forests, and in M. tenuiflora pure thickets, along roads and in resting or abandoned culture lands. This species has an aggregate distribution in the forests and a uniform one in the thickets. It presents a mean density of 9 individuals per m2, with 0.45 of frequency per quadrat and 1.69 m2 of mean coverture, and it has a wide range of tolerance to climatic and edaphic factors, confirming their invasive character. Regionally, the wood is used as fuel and fence construction, and against skin wounds and burns (bark tea, powder and/or ointment), and diverse products, such as shampoos, creams, capsules, soaps, etc., are commercialized. The bark is wrinkled, reddish-brown to grey, fibrous texture, 0.5-1.5 mm thick, resinous and with an astringent odor and flavor, and with a great quantity of tannins. The wood presents extremely short vessel elements, with alternate areolate punctuations, and simple perforated plates, vasicentric axial parenchima, confluent stripes, uniseriated rays, extremely

  7. Biogeochemistry and biodiversity interact to govern N2 fixers (Fabaceae) across Amazon tropical forests

    Dinitrogen (N2)-fixing trees in the Fabaceae fulfill a central role in tropical rainforests by supplying nitrogen from the atmosphere, yet whether they will support a forest CO2 sink in the future by alleviating nitrogen limitation may depend on whether and how they are controlled by local environmental conditions. Theory predicts that soil nutrients govern the function of N2 fixers, yet there have been no large-scale field-based tests of this idea. Moreover, recent findings indicate that N2-fixing species behave differently in biogeochemical cycles, suggesting that any environmental control may differ by species, and that the diversity of N2-fixing trees may be critical for ensuring tropical forest function. In this talk, we will use the RAINFOR dataset of 108 (~1.0 ha) lowland tropical rainforest plots from across the Amazon Basin to test whether the abundance and diversity of N2-fixing trees are controlled by soil nutrient availability (i.e., increasing with phosphorus and decreasing with nitrogen), or if fixer abundance and diversity simply follow the dynamics of all tree species. We also test an alternative - but not mutually exclusive - hypothesis that the governing factor for fixers is forest disturbance. Results show a surprising lack of control by local nutrients or disturbance on the abundance or diversity of N2 fixers. The dominant driver of fixer diversity was the total number of tree species, with fixers comprising 10% of all species in a forest plot (R2 = 0.75, linear regression). When considering the dominant taxa of N2 fixers (Inga, Swartzia, Tachigali) alone, environmental factors (nitrogen, phosphorus and disturbance) became important and clearly governed their abundance. These taxa, which contain >60% of N2-fixing trees in the data set, appear to have evolved to specialize in different local environmental conditions. The strong biogeochemistry-by-biodiversity interaction observed here points to a need to consider individual species or taxa of N2

    Full Text Available Pentaclethra macrophylla Benth (Fabaceae has emerged as one of the top underutilized agroforestry species with considerable economic and nutritional value in West and Central Africa where the species is endemic and exploited by farmers. However, the species suffers from a level of exploitation that is unsustainable. This dramatically decreases the natural resource base. Key information such as tree variation is needed to develop an efficient strategy for its domestication. This study therefore assesses the species phenotypic variation in two populations in the forest zone of Cameroon. Overall, 49 trees (19 in Lomie and 30 in Djoum were sampled. Tree characteristics (diameter at breast height (DBH, height, crown diameter, pod (number of seeds per pod, seed (width, length, thickness, weight and kernel traits (weight were recorded. All these parameters were subjected to a combination of multivariate, PCA and cluster analyses. Results revealed four clusters of P. macrophylla trees with cluster IV considered as the best because it contains four elite trees (LOM/PM/09, LOM/PM/13, LOM/PM/15 and LOM/PM/16 with desirable tree characteristics. Clusters were further considered as different groups of trees, and seeds and kernel traits variation assessed using ANOVA analysis. Significant differences in mean kernel weight occured between groups. Cluster IV presented the highest mean kernel weight (19.25 ± 0.16 g, while cluster III had the lowest (13.28 ± 0.57 g. Within cluster IV, the highest kernel weight (25.83 ± 5.62 g was found in tree number LOM/PM/09. Kernel weight was found to be positive and strongly correlated (r = 0.95 with seed weight. We can conclude that there is phenotypic variation between the trees of P. macrophylla in terms of DBH, height, crown diameter, number of seeds, seed width, seed length, seed thickness, seed and kernel weight. Results obtained in this study could serve as a useful guide for the selection of targeted P. macrophylla

    Full Text Available AbstractLeishmaniasis and fungal infection treatment efficacy is limited by toxicity and ever increasing resistance to available drugs, requiring development of alternative compounds. The richness of Cerrado plant antimicrobial secondary metabolites justifies screening of Fabaceae species extracts: Enterolobium ellipticum Benth., Sclerolobium aureum (Tul. Baill. and Vatairea macrocarpa(Benth. Ducke, against Leishmania(Leishmania amazonensis, yeasts and dermatophytes. Among the 26 extracts tested, more than 50% of the total demonstrated significant antifungal activity in comparison to the drug controls (minimal inhibitory concentration 0.12 to ≤31.25 µg/ml. Six extracts capable of complete parasitic growth inhibition had the inhibitory concentration index for 50% values from 9.23 to 78.65 µg/ml. The results led to the selection of the V. macrocarpa ethyl acetate root bark extract for chemical fractionation. This plant, traditionally referred to as angelim-do-cerrado or maleiteira, is used to treat superficial mycoses in Amazonia. A previously unreported pterocarpan vatacarpan together with the known compound musizin was isolated. Vatacarpan demonstrated a minimal inhibitory concentration value of 0.98 µg/ml against Candida albicans ATCC 10231, and thus comparable or superior to fluconazole and amphotericin B. The results add to literature's information the ability of pterocarpans to act as antimicrobial agents.

    Medicinal plants possess unlimited and untapped wealth of chemical compounds with high drug potential which make these plants useful as sources of biomedicines. The rising demand for herbal medicines in the organized manufacturing sector has ruthlessly exploited the wild growing plant population those have bulk use. So for high rate multiplication of different medicinal plants, it is necessary to standardize the protocol for high regeneration. The efficiency of any regeneration is primarily depends on factors like type of explants used, composition of the medium and type of genotype. Here, we have developed a regeneration protocol of Desmodium gangeticum (L.) DC (Salparni, Fam- Fabaceae) a medicinal plant through axillary bud multiplication. Nodal explants from Desmodium gangeticum plants were cultured on Murashige and Skoog's basal medium with Kn or BA at different concentrations. 0.5 mg L(-1) BA in the medium, showed shoot multiplication. Regenerated shoots measuring 3 cm or more were excised and planted on semi solid basal medium supplemented with varying concentrations of either IAA or IBA for induction of rooting. IBA treatment at 1.0 mg L(-1) was the best eliciting 100% rooting response. The in vitro propagation protocol standardized can be highly useful in raising quality planting materials of Desmodium gangeticum for commercial plantation programmes and germplasm conservation.

    Full Text Available Chrysoperla externa (Neuroptera: Chrysopidae larvae can avoid foraging on plants of Crotalaria juncea (Fabaceae after the issuance of floral buds, when the prey of Utetheisa ornatrix (Lepidoptera: Arctiidae incorporate toxic pyrrolizidine alkaloids from this plant. This reduces the predation and favors increasing the number of adults and eggs of this defoliator on crops of this plant. The aim of the present paper was to evaluate some biological and ecological aspects of C. externa and U. ornatrix on the organic crop of C. juncea in the EMBRAPA Maize and Sorghum in Sete Lagoas, Minas Gerais State, Brazil. Chrysoperla externa and U. ornatrix were more abundant in the vegetative and flowering stages of C. juncea, respectively, with caterpillars of this defoliator feeding on leaves and seeds of this plant. The duration of the stages/instars, survival, lifetime fecundity, and oviposition showed that the branches of C. juncea are a suitable food for U. ornatrix. The abundance of adults and larvae of C. externa was lower in the flowering and pods stages of C. juncea, respectively, when the postures of U. ornatrix are present, probably due to the toxicity of the eggs of this prey to this predator. During these stages, C. externa may be reared with alternative hosts, and when the crops of C. juncea are scarce, an artificial diet should be used for rearing this defoliator in the laboratory for biological research and the development of biological control tactics.Larvas de Chrysoperla externa (Neuroptera: Chrysopidae podem evitar o forrageamento sobre plantas de Crotalaria juncea (Fabaceae após a emissão de botões florais, quando presas de Utetheisa ornatrix (Lepidoptera: Arctiidae incorporam alcalóides pirrolizidínicos tóxicos dessa planta.

Estas peculiaridades incluem cutícula mais espessa, córtex mais desenvolvido formado por células parenquimáticas de formas variáveis, sistema vascular em posição central, floema circundado por fibras septadas não lignificadas e medula parenquimática reduzida ou ausente. Pecíolo e raque apresentam córtex reduzido constituído por células parenquimáticas isodiamétricas, sistema vascular periférico, floema envolvido por calota de fibras gelatinosas e medula ampla. Compostos fenólicos foram detectados no vacúolo das células corticais dos pulvinos, enquanto que no córtex e medula do pecíolo e da raque foram observados amiloplastos em abundância e ausência de compostos fenólicos. Em geral, as características estruturais do pulvino de P. pubescens são comuns aos pulvinos das demais espécies de Fabaceae e têm sido relacionadas com a intensificação de trocas laterais de íons e água entre células do córtex e sistema vascular, além de proporcionar maior flexibilidade e capacidade de movimento desta região. Já as características do pecíolo e da raque conferem maior rigidez a estas estruturas foliares.In Pterodon pubescens the primary and secondary pulvini show structural peculiarities in relations of petiole and rachis. These peculiarities include thicker cuticule, more developed cortex with only parenchyma cells with irregular shape, central vascular tissues, presence of septate fibers around the phloem, and absent or reduced pith. Petiole and rachis show reduced cortex constituted by parenchyma isodiameters cells, peripheric vascular tissues surrounded by gelatinous fibers and pith. Phenolic compounds were detected inside vacuole of parenchyma cells of the pulvinus. Starch grains were observed in the parenchyma cells of petiole and rachis

    Full Text Available The impact of habitat fragmentation and isolation on the genetic diversity of populations has attracted much attention in studies of plant conservation. The central-peripheral population hypothesis predicts that peripheral populations have reduced genetic variability, so it is often assumed that they deserve higher conservation priority over central populations. In this work, using amplified fragment length polymorphism (AFLP, we studied the genetic diversity of central and peripheral populations of the Cantabrian endemism Genista legionensis (Fabaceae. At the species level, percentage of polymorphic bands, Nei heterozygosity and Shannon information index were PPB = 89.21%, Hε = 0.246 and I = 0.377, respectively. The study revealed that peripheral populations were smaller in number, with lower levels of genetic diversity compared to the central populations. Furthermore, analysis of molecular variance (AMOVA indicated that most of the variability was partitioned among populations, also supported by principal coordinates analysis. This study indicates that the decrease in diversity from central to peripheral populations could be explained as a result of edge effect and fragmentation through the enhanced inbreeding and genetic drift, and thus supported the view that habitat fragmentation and related edge effect reduce the population genetic diversity. However, the presence of discriminating fragments in the peripheral populations suggests their conservation in order to preserve the genetic diversity in the Cantabrian endemism G. legionensis.El impacto de la fragmentación del hábitat y el aislamiento sobre la diversidad genética de las poblaciones, han despertado mucha atención en estudios de conservación de plantas. La hipótesis de la población centro-periferia predice que las poblaciones periféricas reducen la variabilidad genética, por lo que a menudo se asume que merecen una mayor prioridad de conservación respecto a las poblaciones

    The tropical plant Clitoria ternatea is a member of the Fabaceae family well known for its medicinal values. Heat extraction of C. ternatea revealed that the bioactive fractions contained heat-stable cysteine-rich peptides (CRPs). The CRP family of A1b (Albumin-1 chain b/leginsulins), which is a linear cystine knot CRP, has been shown to present abundantly in the Fabaceae. In contrast, the cyclotide family, which also belongs to the cystine knot CRPs but with a cyclic structure, is commonly found in the Rubiaceae, Violaceae, and Cucurbitaceae families. In this study, we report the discovery of a panel of 15 heat-stable CRPs, of which 12 sequences (cliotide T1-T12) are novel. We show unambiguously that the cliotides are cyclotides and not A1bs, as determined by their sequence homology, disulfide connectivity, and membrane active properties indicated by their antimicrobial activities against Escherichia coli and cytotoxicities to HeLa cells. We also show that cliotides are prevalent in C. ternatea and are found in every plant tissue examined, including flowers, seeds, and nodules. In addition, we demonstrate that their precursors are chimeras, half from cyclotide and the other half from Albumin-1, with the cyclotide domain displacing the A1b domain in the precursor. Their chimeric structures likely originate from either horizontal gene transfer or convergent evolution in plant nuclear genomes, which are exceedingly rare events. Such atypical genetic arrangement also implies a different mechanism of biosynthetic processing of cyclotides in the Fabaceae and provides new understanding of their evolution in plants.

    Full Text Available "n  Background and purpose of the study: Fabaceae is the third largest family of flowering plants. Lack of essential oils in the plants of this family can be an advantage in search for safe and effective medicines. In this study the anticonvulsant effect of the leaves of Albizzia julibrissin, Acacia juliflora, Acacia nubica and aerial parts of Astragalus obtusifolius was evaluated in pentylenetetrazole (PTZ and maximal electroshock (MES seizure tests. "n  Methods: The hydroalcoholic extracts of the plants were obtained by percolation. Different doses of the extracts were injected to the mice intraperitoneally (i.p. and occurrence of clonic seizures induced by PTZ (60 mg/kg, i.p. or tonic seizures induced by MES (50 mA, 50Hz, 1sec were monitored up to 30 min after administration. Acute toxicity of the extracts was also assessed. The safe and effective extract was then fractionated by dichloromethane and anticonvulsant activity of the fractions was determined. Finally, the constituents of the extract and the fractions were screened by thin layer chromatography. "n  Results: Among the extracts, only A. obtusifolius extract showed low toxicity and protective effect against clonic seizures with ED50 value of 3.97 g/kg. Fractionation of the extract led to increase in anticonvulsant activity and ED50 value of 2.86 g/kg was obtained for the aqueous fraction. Phytochemical screening revealed the presence of alkaloids, flavonoids, anthrones and saponins in the aqueous fraction. "n  Major conclusion: The presence of anticonvulsant compounds in A. obtusifolius suggests further activity-guided fractionation and analytical studies to find out the potential of this plant as a source of anticonvulsant agent.

  4. Genetic and clonal diversity of the endemic ant-plant Humboldtia brunonis (Fabaceae) in the Western Ghats of India

    Humboldtia brunonis (Fabaceae, Caesalpinioideae) is a dominant self-incompatible ant-plant or myrmecophyte, growing as an understorey tree in high-density patches. It is endemic to the biodiversity hotspot of the southern Western Ghats of India and, besides ants, harbours many endemic invertebrate taxa, such as bees that pollinate it as well as arboreal earthworms, within swollen hollow stem internodes called domatia. Using inter simple sequence repeat (ISSR) markers, three geographically separated populations were found to be multiclonal, characterized by high levels of clonal diversity. Values for the Simpson diversity index ranged between 0.764 and 0.964, and for Fager’s evenness index between 0.00 and 0.036 for neighbourhoods within populations. This myrmecophyte was found to combine sexual recruitment (66.7%) and clonal production (33.3%) as methods of reproduction. Moderate amounts of genetic diversity at the species level were observed, with 52.63% polymorphism, and moderate values of Shannon’s diversity index (0.1895) as well as of Nei’s gene diversity (0.1186). In each population, observed genotypic diversity was significantly lower than expected, indicating significant genetic structure. Neighbour-joining trees demonstrated that Agumbe, which is the most northern population examined and geographically twice as far away from the other two populations, grouped separately and with larger bootstrap support from a larger cluster consisting of the Sampaji and Solaikolli populations, which are closer to each other geographically. Some neighbourhoods within each population showed spatial genetic structure even at small spatial scales of < 5 m. A combination of clonality and short-distance pollen movement by small pollinating bees (Braunsapis puangensis) coupled with primary ballistic seed dispersal, and possible secondary seed dispersal by rodents, may contribute to spatial genetic structure at such small scales. The clonality of H. brunonis may be a factor

    Full Text Available The present research work evaluates the photoabsorptive property of different extracts of the leaves of Pongamia pinnata (L. Pierre, Fabaceae, in the ultraviolet region (200-400 nm and its comparison with a well-established standard sunscreen drug, p-aminobenzoic acid (PABA. The shade-dried leaves of the plant were extracted in Soxhlet apparatus using three different solvents, i.e., water, methanol and acetone. The extracts were concentrated by evaporation of the solvent and finally dried to get dry extracts. Then, 20 mg of the dry extracts was dissolved in the respective solvents and their absorption spectra were measured using UV-visible spectrophotometer. Absorbance of different concentrations of the extracts, i.e., 5, 10, 15 and 20 mg/100 ml was read at their respective wavelengths (λmax of maximum absorption. The aqueous and methanol extracts were found to be highly effective in the UVB and moderately effective in the UVA region. Acetone extract was found to greatly absorb exclusively in the UVA region. The known standard drug PABA showed its protective action in the UVB and UVC regions with least effectiveness in the UVA region. The extracts of the leaves of the plant under study showed extremely good absorbance throughout the UV region including UVA region. The P. pinnata extract can be used to formulate highly effective sunscreen preparations as it will enhance and effectively contribute to the UV absorbing properties of a conventional sunscreen. It will also help in broadening the UV protection ability of the sunscreens along with the greatest advantage of avoiding the adverse and undesired effects of synthetic sunscreen compounds.

    Flowers from several common Mediterranean shrubs, such as those from the Cytisus genus and Genista genus (tribe Genisteae/Fabaceae) have long been used for medicinal purposes and seasoning in the northeastern Portuguese region. Despite, the shade-drying traditionally used to process these plants, freeze-drying is claimed to better preserve the quality of medicinal plants. Herein, the effects of drying process in the antioxidants composition and properties of Cytisus multiflorus, Cytisus scoparius, Cytisus striatus and Pterospartum tridentatum were evaluated. Freeze-dried P. tridentatum revealed the highest antioxidant properties (EC(50) values ≤ 0.15 mg/ml). Freeze-drying benefits were confirmed showing, the samples submitted to this process, higher antioxidant activity and higher concentrations of hydrophilic (phenolics, ascorbic acid and sugars) and lipophilic (tocopherols, chlorophylls and lycopene) compounds. This process could be applied in scale-up treatments of the studied plants for cosmetic or pharmaceutical applications.

Steud., Fabaceae, em uma área de caatinga no estado de Pernambuco, Nordeste do Brasil. Foi utilizada metodologia analítica por complexação com cloreto de alumínio para quantificar a concentração de flavonóides contidos nos extratos foliares de B. cheilantha, por meio de espectrofotometria no visível. De forma geral, o efeito de borda afeta a produção de flavonóides, entretanto, não foi possível correlacionar a produção de flavonóides e a pluviosidade, demonstrando que a espécie avaliada utiliza outra estratégia como resposta às pressões ambientais.The present study evaluated the influence of the edge-effect and rainfall on flavonoid content in individuals of Bauhinia cheilantha (Bong. Steud., Fabaceae, in an area of caatinga vegetation in Pernambuco State, northeastern Brazil. The analytical methodology used aluminum chloride binding to quantify flavonoid concentrations by visible light spectrophotometry in leaf extracts of B. cheilantha. In general, forest edges influenced flavonoid production, but it was not possible to relate production with rainfall levels. These results demonstrate that this species uses various strategies to respond to environmental variables.

    Full Text Available Onobrychis Miller is the second largest genus of Fabaceae in Iran with nearly 60 species. These species are used as valuable forage plants. Onobrychis sect. Onobrychis with nearly 15 species in Iran is one of the important sections of the genus. Onobrychis transcaspica V. Nikitin, is one of the species of this section that is distributed in NE of Iran. To determine intraspecific variations in O. transcaspica from taxonomic point of view and effective ecological factor, data were collected using special station method. In this way, four special stations were recognized for O. transcaspica in NE of Iran. Results from floristic data (Floristic composition of each special station analysis with MVSP software by PCO method, led to identification of 3 separate groups that was indicative of existence of intraspecific diversity. Morphometric data analysis of individual collected from each special station, by using 65 vegetative and reproductive characters, with PCO and UPGMA methods, confirmed 3 mentioned floristic groups. Ecologic data analysis with CCA Method showed the presence of 3 phenoecodeme based on 3 morphologic groups resulting from altitudinal variations.

    2014-12-01

    The purpose of this study was to investigate the reproductive phenology and sharing of floral resource (nectar) of Dahlstedtia pinnata (Benth.) Malme. (Fabaceae), endemic of Atlantic forest, among hummingbirds. For the phenology, we looked at the presence of reproductive structures in the plants, and for floral resource sharing, the frequency of potential pollinators and foraging behaviors were examined. This study was conducted in Pedra Branca State Park, in state of Rio de Janeiro, in a dense ombrophilous forest, between August 2010 and August 2011. Flowering occurred between December 2010 and March 2011, and fruiting between April and June 2011. Hummingbirds' foraging schedules differed significantly, with legitimate visits to the flowers occurring in the morning and illegitimate visits occurring during late morning and the afternoon. Five species visited flowers, three of which were legitimate visitors: Phaethornis ruber, P. pretrei, and Ramphodon naevius. Amazilia fimbriata and Thalurania glaucopis females only visited illegitimately. Phaethornis ruber robbed nectar (78% of illegitimate visits, n=337). Ramphodon naevius, with a territorial foraging behavior and a body size bigger than that of other observed hummingbird species, dominated the floral visits, which suggests that D. pinnata is an important nourishing resource for this endemic bird of the Atlantic forest, currently globally categorized as Near Threatened.

    Full Text Available Preliminary observations of variability between some morphotypes of bambara groundnut (Vigna subterranea L. Verdc., Fabaceae from Côte d’Ivoire. Bambara groundnut (Vigna subterranea L. Verdc., is a food legume mainly cultivated by women for whom it represents a source of income for the household. In Côte d’Ivoire, the cultivation of bambara groundnut is located in the western and northern parts of the country. These zones are characterised by contrasted agroecology including tropical rain forest and dry savanna. In these zones, bambara groundnut plays a key role in both food and culture of peoples. Four morphotypes of Côte d’Ivoire (ICU, BPR, RBU, NFU were used in a preliminary study to assess the phenotypic variability between morphotypes. For each morphotype, 100 individuals were sampled to analyse 26 agromorphological traits selected from the list of bambara groundnut descriptors. Results of statistical analyses showed an important variability among morphotypes suggesting that 22 of these characters could be powerful to distinguish diversity among bambara groundnut morphotypes of Côte d’Ivoire. Three morphotypes (ICU, BPR and RBU show a shorter reproductive cycle than the other (NFU. In our experimental conditions, morphotypes with a shorter reproductive cycle give a higher percentage of matured pods (87 to 95%, compared to morphotype NFU (60%. The morphotype ICU was particularly earlier, maturing 90 days after sowing (DAS, whereas the long reproductive cycle morphotype (NFU required about 137 days. Based on the analysed agronomic traits, possibilities to improve bambara groundnut yield and to promote its cultivation in Côte d’Ivoire are discussed.

  3. Hexavalent chromium-induced differential disruption of cortical microtubules in some Fabaceae species is correlated with acetylation of α-tubulin.

    2016-03-01

    The effects of hexavalent chromium [Cr(VI)] on the cortical microtubules (MTs) of five species of the Fabaceae family (Vicia faba, Pisum sativum, Vigna sinensis, Vigna angularis, and Medicago sativa) were investigated by confocal laser scanning microscopy after immunolocalization of total tubulin with conventional immunofluorescence techniques and of acetylated α-tubulin with the specific 6-11B-1 monoclonal antibody. Moreover, total α-tubulin and acetylated α-tubulin were quantified by Western immunoblotting and scanning densitometry. Results showed the universality of Cr(VI) detrimental effects to cortical MTs, which proved to be a sensitive and reliable subcellular marker for monitoring Cr(VI) toxicity in plant cells. However, a species-specific response was recorded, and a correlation of MT disturbance with the acetylation status of α-tubulin was demonstrated. In V. faba, MTs were depolymerized at the gain of cytoplasmic tubulin background and displayed low α-tubulin acetylation, while in P. sativum, V. sinensis, V. angularis, and M. sativa, MTs became bundled and changed orientation from perpendicular to oblique or longitudinal. Bundled MTs were highly acetylated as determined by both immunofluorescence and Western immunoblotting. Tubulin acetylation in P. sativum and M. sativa preceded MT bundling; in V. sinensis it followed MT derangement, while in V. angularis the two phenomena coincided. Total α-tubulin remained constant in all treatments. Should acetylation be an indicator of MT stabilization, it is deduced that bundled MTs became stabilized, lost their dynamic properties, and were rendered inactive. Results of this report allow the conclusion that Cr(VI) toxicity disrupts MTs and deranges the MT-mediated functions either by depolymerizing or stabilizing them. PMID:26015161

Porém, informações sobre seu potencial tóxico são escassos na literatura. O objetivo deste estudo foi estabelecer a toxicidade oral aguda e os possíveis efeitos neurotóxicos relacionados à ingestão do óleo-resina de Copaifera reticulata Ducke, Fabaceae, em ratas Wistar. O estudo foi conduzido com quinze ratas nulíparas distribuídas nos grupos de doses 300 e 2000 mg/kg pc de óleo-resina administrado por gavagem. Os resultados obtidos mostraram que nestas doses não houve sinais clínicos de toxicidade ou neurotoxicidade, alteração no consumo de ração ou alteração no peso corpóreo. A dose letal aguda foi estimada como maior que 2000 mg/kg pc e classificada como categoria 5, segundo o Guia OECD 423. Estes resultados indicam que existe uma relativa margem de segurança para o uso do óleo-resina de copaíba como agente terapêutico, embora estudos toxicológicos adicionais sejam ainda necessários, principalmente com a administração repetida de baixas doses.Copaiba oil-resin obtained from Copaifera L. genus, Fabaceae, is largely used in popular medicine as antinflammatory, antimicrobial and antitumoral.

    The rise of modern American scholarship on China was largely attributed to the establishment of the American Joint Committee on Contemporary China (JCCC) in 1959 which sponsored all kinds of activities to promote Chinese studies, ranging from institutional support and financial resources to training courses. Since then, American study of China has entered into a period of sustainability that features academic and group-oriented research. It has become a mainstream discipline in American social science studies.1 There are some distinctive differences between early sinology and modern Chinese Studies: the latter is much more concentrated on the study of issues, comparative historical studies, and contemporary Chinese society. American Chinese studies stresses empirical research, textual data, and the application of theory to practice.Shanghai.

O presente trabalho objetivou estudar os impactos da invasão de P. juliflora sobre a fitodiversidade e a estrutura do componente arbustivo-arbóreo, em remanescentes de caatinga no Estado da Paraíba. Usando-se o método de parcelas, foram amostrados quatro ambientes, nos quais os indivíduos de todas as espécies arbustivas e arbóreas foram inventariados e medidos, estimando-se os parâmetros estruturais das comunidades. Também foi calculada a diversidade, pelo índice de Shannon-Wiener (H’ e o índice de impacto ambiental de exóticas (IIAE. No total, foram amostradas 19 famílias, 35 gêneros e 39 espécies. A invasora foi responsável por mais de 70% de toda a estrutura dos ambientes inventariados. A baixa diversidade e o elevado valor de impacto ambiental obtidos para os ambientes invadidos revelaram, conjuntamente com os dados de estrutura das populações, os graves impactos que P. juliflora provoca nas comunidades invadidas. Evidencia-se com isso a formação de sistemas monodominados pela espécie invasora, o que revela a necessidade de controle efetivo de P. juliflora para se proteger o patrimônio genético autóctone.It is estimated that invader populations of algaroba Prosopis juliflora (Sw.

    BIGGERS, J D; FRITZ, H I; HARE, W C; MCFEELY, R A

    1965-06-18

    Studies of the chromosomes of four American marsupials demonstrated that Caluromys derbianus and Marmosa mexicana have a diploid number of 14 chromosomes, and that Philander opossum and Didelphis marsupialis have a diploid number of 22. The karyotypes of C. derbianus and M. mexicana are similar, whereas those of P. opossum and D. marsupialis are dissimilar. If the 14-chromosome karyotype represents a reduction from a primitive number of 22, these observations suggest that the change has occurred independently in the American and Australasian forms.

    Weaver, C N; Hinson, S

    2000-04-01

    Since Asian Americans have demographic and labor force characteristics more similar to Euro-Americans than African Americans, one might predict that their job satisfaction would be more like the former than the latter. And, because Asian Americans originating from different countries are heterogeneous in language, culture, and recency of immigration, one might predict that they may report obtaining different amounts of satisfaction from their jobs. However, data from 21 nationally representative opinion surveys from 1972 through 1996 suggest the opposite. Asian Americans (n = 199) reported job satisfaction more like African Americans (n = 1,231) than Euro-Americans (n = 10,709), and Asian Americans from China (n = 53), Japan (n = 44), India (n = 55), and the Philippines (n = 47) reported similar job satisfaction. These differences persisted when age, education, occupation, and personal income were held constant.

    Grant Wood's "American Gothic," intended to represent the Depression Era, Midwestern farmer, has been regarded by many as the stereotypical representation of a true American farmer for decades.

    Full Text Available The nation, as artifact of modernity, assumes particularities in America such as the colonization and genocide of original peoples which still weighs as a never ending comeback. Nevertheless, capital, with its overwhelming force, destroyed peoples, cultures, traditions and landscapes. Latin America faces the challenge of uniting beyond the necessities of capital, and beyond two languages, spanish and portuguese. All of which has full validity at present with the blocks UNASUR and ALBA. Ethnocentricity is postulated as the exclusive condition of all possible humanity and, as programme, racism without races; Latin American miscegenation, as the potential for unity and the strength of emancipation as a project. Our intellectuals, who constructed a unique and superlative literature, are the lighthouses in the development of a nationalism without races. Anthropology in debate with psychoanalysis can become a compass in rethinking our America.

  15. American Urban Star Fest

    Science.gov (United States)

    Pazmino, John

    2003-12-01

    Over the last couple of decades New York City implemented, and continues to carry out, several schemes of eradicating luminous graffiti. One result has been the gradual recovery of the natural night sky. By 1994 the normal clear sky transparency over Manhattan deepened to fourth magnitude and has been slowly creeping deeper, until in 2002 it is at magnitude 4 to 4.5. In the spring of 1995, during some lazing on a Manhattan rooftop under a sky full of stars, several New York astronomers hatched the idea of letting the whole people celebrate the renewed starry sky. In due course they, through the Amateur Astronomers Association, engaged the New York City Parks Department and the Urban Park Rangers in an evening of quiet picnicking to enjoy the stars in their natural sky. Thus the Urban Star Fest was born. The event thrilled about 3,000 visitors in Central Park's Sheep Meadow on Saturday 30 September 1995. This year's Fest, the eighth in the series demonstrated the City's upper skyline of stars on Saturday 5 October 2002 to about 2,200 enthused visitors. Although the Fest is always noted as cancelable for inclement weather, so far, it has convened every year, with attendance ranging from 4,000 down to a mere 1,000, this latter being under the smoke plume of the World Trade Center in 2001. Despite this swing in attendance, the American Urban Star Fest is America's largest regularly scheduled public astronomy event. Of course, special occasions, like comets or eclipses, can and do attract far larger interest both in the city and elsewhere. The presentation shows the setup and program of the American Urban Star Fest, to illustrate how the general public can actively become aware of the night sky and see for themselves the result of their very own efforts at removing light pollution--and note where improvement is yet to come.

    2007-11-15

    North America is an energy community fortunate to be endowed with a rich and varied resource base. It consumes about a third of the world's energy and produces about one quarter of world energy supply. North America depends on a mix of complementary energy sources that should remain competitive but not in conflict. The current supply mix varies between Canada, the United States and Mexico, but fossil fuels are dominant across the region, leaving the three member countries vulnerable to a myriad of risks associated with traditional supply sources. Energy trade between all three countries is also a major contributor to the region's economy. Thus, the impetus for collaboration across the region has grown out of the common goals of energy security and economic prosperity. The goal of the WEC regional group was to discuss avenues for advancing North American cooperation and coordination on a range of energy issues. An additional objective was to develop policy recommendations that will facilitate effective development and use of the region's energy resources. Results and recommendtaions are summarized from three forums that focused on the pertinent issues of energy trade, energy efficiency and energy diversification. The inaugural forum (Energy Trade) was held in Washington, D.C. in the fall of 2005. The following summer, the second forum (Energy Efficiency) took place in Mexico City. The third forum (Energy Diversification) was hosted in Halifax, Nova Scotia.

The art tradition involved telling stories to each generation in black families. The black culture elevated by tradition created hope to determine their personal freedom to escape from poverty of enslavement and to establish a way of life through tradition. A way of personal freedoms was through getting a good education that lead to a better foundation and a better way of life.

  2. Colonial American Astronomy

    Yeomans, Donald K.

    2007-12-01

    While a foundation of German scientific methods enabled the rapid growth of North American Astronomy in the nineteenth century, during the seventeenth and most of the eighteenth centuries, the colonial men of science looked only to the English mother country for scientific patronage and guidance. An essay on fundamental astronomy appeared in one of the annual colonial almanacs as early as 1656, telescopic observations were made about 1660 and the first original colonial astronomical work was published by Thomas Danforth on the comet of 1664. By 1671 the Copernican ideas were so espoused at Harvard College that a physics class refused to read a Ptolemaic textbook when it was assigned to them by a senior instructor. At least in the Cambridge-Boston area, contemporary colonialist had access to the most recent scientific publications from the mother country. Observations of the great comet of 1680 by the Almanac maker, John Foster, reached Isaac Newton and were used and gratefully acknowledged in his Principia. During the seventeenth century the colonial interest in astronomy was more intense than it was for other sciences but colonists still occupied a position in the scientific backwater when compared with contemporary European scientists. Nevertheless, the science of astronomy was successfully transplanted from England to North America in the seventeenth century.

  3. Geothermal energy for American Samoa

    Energy Technology Data Exchange (ETDEWEB)

    1980-03-01

    The geothermal commercialization potential in American Samoa was investigated. With geothermal energy harnessed in American Samoa, a myriad of possibilities would arise. Existing residential and business consumers would benefit from reduced electricity costs. The tuna canneries, demanding about 76% of the island's process heat requirements, may be able to use process heat from a geothermal source. Potential new industries include health spas, aquaculture, wood products, large domestic and transhipment refrigerated warehouses, electric cars, ocean nodule processing, and a hydrogen economy. There are no territorial statutory laws of American Samoa claiming or reserving any special rights (including mineral rights) to the territorial government, or other interests adverse to a land owner, for subsurface content of real property. Technically, an investigation has revealed that American Samoa does possess a geological environment conducive to geothermal energy development. Further studies and test holes are warranted.

  1. Pasteur, Koch and American bacteriology.

    Science.gov (United States)

    Gossel, P P

    2000-01-01

    This study traces American awareness of the work of Louis Pasteur and Robert Koch from the 1860s to the 1890s. In the years before the Civil War, American interest in germ theories had appeared at times of epidemics and persisted to a limited extent among physician-microscopists. Discussions of Pasteur's work occurred primarily in the context of spontaneous generation and antisepsis. Few Americans imitated his work on immunology or studied with Pasteur, but his work on immunity influenced their faith in the potential of bacteriology as a solution to problems of infectious disease. Koch's discoveries of the bacterial agents of tuberculosis and cholera stimulated American medical and public health interest in bacteriology in a more practical way. Americans learned Koch's methods by taking his courses and imported them directly into their own laboratories. A context of enthusiasm for science, educational reform, and problems of infectious disease associated with urbanization and changes in agriculture aided the growth of bacteriology in the American context.

  4. North American Foreign Fighters

    Directory of Open Access Journals (Sweden)

    Michael Noonan

    2014-12-01

    Full Text Available While the phenomenon of so-called “foreign fighters” is in no way new the past thirty-plus years has shown a marked increase in the numbers of individuals traveling abroad to fight in civil conflicts in the Muslim world. The crisis in Syria (2011-present has created a massive influx of such individuals going to fight. Of particular concern in western capitals has been the numbers of individuals from those countries that have gone to fight in that conflict which has since crossed the border into neighboring Iraq with the establishment of the socalled “Islamic State” and threatens to broaden the conflict into a larger regional sectarian conflagration. While the numbers of such participants from Western Europe have been greater than those who have gone from the United States and Canada there are legitimate concerns in both Washington, DC, and Ottawa about American and Canadian citizens who have gone—or attempted to go—to fight there and in other locales such as the Maghreb and Somalia. The analysis here will provide some background on the foreign fighter phenomenon, discuss the foreign fighter flow model, explore the issue from both Canadian and US perspectives to include providing details of some original research categorizing the characteristics of a small sample of US and Canadian fighters and those who attempted to go and fight, discuss how both governments have attempted to deal with the issue, and offer some policy prescription for dealing with this issue that is of importance to both international security writ large and domestic security in the US and Canada.

  5. Immigration reform, American style.

    Science.gov (United States)

    Papademetriou, D G

    1984-01-01

    This article reviews the background of the proposed Immigration and Reform Act (also known as the Simpson-Mazzoli bill), which seeks to overhaul US immigration law for the first time since 1952. This bill is consistent with President Reagan's hard line on border enforcement and mandates stiff penalties for those who transport illegal aliens for commercial advantage or private profit. It further offers Mexico preferential treatment in immigration (40,000 additional visas/year). It includes an amnesty program to offer legal status to qualified illegal residents. The bill directs the President to develop a secure national worker identification system and would create a large-scale temporary foreign agricultural program for perishable commodities. Agricultural workers' families would not be eligible to accompany them unless they also obtain temporary visas. Foreign temporary workers, employable only in cases where local domestic workers are not available, must be provided with wages and working conditions equal to those prevailing among domestic workers. Stiff penalties are stipulated for employers who fail to abide with the terms of the program. In the author's opinion, this bill fails to appreciate the global character of international migration and its complexity. It relects a fundamental ambivalence about a strictly controlled main gate versus a back door approach to immigration as well as the conflicting images of the US as a nation of immigrants versus the historical reality of American nativism and xenophobia. Needed are comprehensive initiatives whose mutually reinforcing components can address the multiple dimensions of the immigration problem within a framework that does not ignore workers who have contributed to the economic well-being of the US, regardless of their legal status.

    The American Culture Wars have had a great impact on gender and racial relations in the US and have triggered the transformation of its literary canon. American literature textbooks in China. however, are not reaping the fruits of the US cultural debates, a conclusion based on a survey of eight popular textbooks recently published by prestigious publishing houses.Given the significance of the US sociopolitical base in shaping the canon and the lecturers' dependence on the textbooks, they need immediate and drastic improvement. The paper is rounded off with some cues on what to improve.

    Language is a key component part of culture. It reflects culture. As a variety of British English, American English, especially American words reflect American culture, including their custom, their view of value, their character traits. Being a melting pot, American words melt a lot of loanwords. The exaggerated use of words shows Americans are self-confidence. They also use beautified words to show their wish to life, to future. They can use common words, usually slang to express special ideas. By doing so, they create something new and original. Learning American English, especially studying American words, we can see some typical traits of American culture.

  9. Pavlov's position toward American behaviorism.

    Windholz, G

    1983-10-01

    Pavlov's development of the conditional reflex theory coincided with the rise of American behaviorism. Substituting an objective physiology for a subjective psychology, Pavlov saw in the rise of American behaviorism a clear confirmation of his method and theory. But in the early 1930s, Lashley attacked Pavlov's theory of specific cerebral localization of function, proposing instead the concept of an internal cerebral organization; Guthrie objected to Pavlov's centralist interpretation of conditioning, proposing instead a peripheralist interpretation; while Hull challenged Pavlov's theory of sleep and hypnosis as the manifestations of inhibition. Pavlov replied with critiques of Lashley's, Guthrie's, and Hull's views, and, convinced that Lashley and Guthrie misunderstood his position, repeated his method's and theory's basic propositions. Yet, Pavlov never gave up the expectation that American behaviorism would accept his conditional reflex theory and saw in Hunter's 1932 statements a support of his assumptions.

  11. Confidentiality and American semen donors.

    Karow, A M

    1993-01-01

    Most American donor insemination programs include a policy of complete confidentiality concerning the donor of the semen. This is the result of a long legal tradition of American constitutional law. However, some slight abridgement of this body of legal decisions might be very much in the best interests of children arising from donor insemination, and even--in most cases, in fact--the donors themselves. With regard to the children, the factors involved are both those of genetic counseling, should the need arise, and psychological development. Of course, as at present, the donor must be relieved of all responsibility, both legal and financial. PMID:8348162

This study examines the acculturation, dietary habits and anthropometric measurements in a sample of 210 first generation Filipino American immigrants in New Jersey (NJ. Acculturation was measured using the Short Acculturation Scale for Filipino Americans (ASASFA. Dietary acculturation was measured using the Dietary Acculturation Questionnaire for Filipino Americans (DAQFA and dietary intake was determined using the Block’s Brief Food Frequency Questionnaire (BFFQ. Anthropometric measurements were obtained including weight, height and waist circumference. Acculturation had a significant negative relationship with Filipino Dietary acculturation. Western dietary acculturation was significantly correlated with caloric intake (r(208 = 0.193, p < 0.01, percentage fat intake (r(208 = 0.154, p < 0.05, percentage carbohydrate intake (r(208 = −0.172, p < 0.05, Body Mass Index (BMI (r(208 = 0.216, p < 0.01 and waist circumference (r(208 = 0.161, p < 0.01.

    The current study focused on a group of Chinese-American professionals working in a scientific environment in the San Francisco Bay area. One of the goals of the present study is to determine to what extent do the Chinese cultural values impact job performance, interpersonal relationships and perception of job satisfaction. This was carried out by identifying the important motivational factors and optimal working conditions which provided career satisfaction for the Chinese-American professionals. Comparisons were made between the US born and foreign-born respondents to determine differences, if any, in their perceptions relative to career satisfaction due to varying acculturation levels. In addition, this study identified barriers to career advancement and compared these barriers with the results of another survey on the Chinese-American professionals working in government, industry and private sector in the Bay area. A structured survey questionnaire was designed by the investigator and sent to 167 Chinese-American professionals, composed of both US-born and foreign-born. 41 refs., 12 figs., 8 tabs.

The objective of this study was to estimate the level of participation in aerobic, muscle-strengthening, and flexibility activities among Americans aged 50 years or older.MethodsUsing population-based data from the 2001 National Health Interview Survey, we classified qualified respondents (N = 11,969 according to whether they met the activity criteria used in Healthy People 2010 goals for leisure-time participation in regular aerobic physical activity, vigorous-intensity aerobic activity, strength-training activity, and flexibility activity. We also classified respondents according to their level of aerobic activity (i.e., inactive, insufficiently active, and regularly active.ResultsWe estimated that 46.4% of older Americans engaged in no leisure-time aerobic activity; that 26.1% were regularly active (participated in light- to moderate-intensity aerobic activities at least 5 days per week for at least 30 minutes or vigorous-intensity activities at least 3 days per week for at least 20 minutes; that 16.2% participated in vigorous-intensity aerobic activities at least 3 days per week for at least 20 minutes; that 13.7% participated in strength-training activities at least 2 days per week; and that 24.5% participated in flexibility activities at least 1 day per week. Among the 26.1% of older Americans who were regularly active, 30.5% engaged in strengthen-training activities at least 2 days per week. Overall, only 8.2% of older Americans met the criteria for both aerobic and strength-training activity.ConclusionAs of 2001, the percentage of older Americans who met recommended activity levels of physical activity were well below the goals for U.S. adults in Healthy People 2010.

  20. Depression among Asian Americans: Review and Recommendations

    Directory of Open Access Journals (Sweden)

    Zornitsa Kalibatseva

    2011-01-01

    Full Text Available This article presents a review of the prevalence and manifestation of depression among Asian Americans and discusses some of the existing issues in the assessment and diagnosis of depression among Asian Americans. The authors point out the diversity and increasing numbers of Asian Americans and the need to provide better mental health services for this population. While the prevalence of depression among Asian Americans is lower than that among other ethnic/racial groups, Asian Americans receive treatment for depression less often and its quality is less adequate. In addition, the previous belief that Asians somatize depression may become obsolete as more evidence appears to support that Westerners may “psychologize” depression. The cultural validity of the current DSM-IV conceptualization of depression is questioned. In the course of the review, the theme of complexity emerges: the heterogeneity of ethnic Asian American groups, the multidimensionality of depression, and the intersectionality of multiple factors among depressed Asian Americans.

    In this study the authors used cluster analysis to create racial identity profiles for a sample of Asian Americans using the People of Color Racial Identity Attitudes Scale (PCRIAS). A four-cluster solution was chosen: each cluster corresponded to one PCRIAS subscale and was named accordingly. Scores on the Asian American Racism-Related Stress Inventory and the Color-Blind Racial Attitudes Scale were compared across clusters. As expected, the Dissonance and Immersion clusters were characterized by relatively high racism-related stress and low levels of color-blind attitudes; the Conformity cluster showed roughly the opposite pattern. Surprisingly, the Internalization cluster showed a pattern similar to that for Conformity and thus may reflect "pseudoindependence" as discussed by Helms. PMID:16881750

    In his paper, "Latin American and Comparative Literature," Roberto González Echevarría asks whether comparative literature, a literary discipline dedicated to the proposition that linguistic boundaries must be transcended, can overcome the "cultural arrogance" of the "Eurocentrism" that he believes pervades it currently. González Echevarría argues that if it is to endure, comparative literature will have to undergo "a truly pitiless redefinition," one that effectively displaces "the hegemonic...

    2008-10-01

    The current study examined ethnic differences in horizontal and vertical dimensions of individualism and collectivism among 96 African American and 149 European American college students. Participants completed the 32-item Singelis et al. (1995) Individualism/Collectivism Scale. Multivariate analyses of variance results yielded a main effect for ethnicity, with African Americans being significantly higher on horizontal individualism and European Americans being higher on horizontal collectivism and vertical individualism. A moderated multiple regression analysis indicated that ethnicity significantly moderated the relationship between individualism and collectivism. Individualism and collectivism were significantly and positively associated among African Americans, but not associated among European Americans. In addition, collectivism was related to grade point average for African Americans but not for European Americans. Contrary to the prevailing view of individualism-collectivism being unipolar, orthogonal dimensions, results provide support for individualism-collectivism to be considered as unipolar, related dimensions for African Americans.

    A national, Web-based survey of 1,219 African American, Latina/o, Asian American, and European American psychology graduate students revealed both similarities and differences in experiences and perspectives. Mentoring was found to be the strongest predictor of satisfaction across groups. Academic supports and barriers, along with perceptions of diversity within the academic environment, were also important predictors of satisfaction. Students of color perceived less fairness of representation of their ethnic group within psychology than European American students, and a greater linkage between aspects of the graduate school experience and their ethnicity. Limitations of the study and implications for future research and action are discussed.

    Full Text Available This study focuses on the depiction of homosexuality in American films. It is intended to identify the images of gays depicted in American films as well as the characteristics of American gay movies. It incorporates library research by applying an analytical descriptive approach in analyzing the data. The symbol and reflective theory is used to analyze 18 American movies and 14 gay films from other countries in the early 2000s. It shows that gay films can attract audiences by describing gays as the objects for laughs; gays revealing their sexual identities; sexual scenes of gays; masculine gay men; and violence in gay life. They appear in genres like drama, comedy, romance, detective, western, and horror/mystery with two images of gay people shown in American gay movies; they are the portrait of gays as a minority and the pessimism. However, it also shows that some American gay films picture good gay life, happy gay couples, gay marriage, etc.

    Koreans are a relatively new and fast-growing immigrant group in the United States. Research has shown that immigration experiences are associated with depression, whereas acculturation and social support are moderating factors. Korean culture is informed by Confucianism, which emphasizes family integrity, group conformity, and traditional gender roles, and has influenced how Korean immigrants conceptualize depression, express depressive symptoms, and demonstrate help-seeking behavior. An understanding of Korean patterns of manifesting and expressing depression will be helpful to provide culturally appropriate mental health services to Korean American immigrants. PMID:18207052

    Chinese and Americans have different cultural background. They value different principles in expressing compliments and respond to them. Chinese tend to be self-denial to show modesty. Americans have a tendency of self-praising to demonstrate their confidence. Based on Leech's politeness principle, the paper analyzes typical instances. In conclusion, as language learner, we should aware it and prepare to be bicultural instead of bilingual. As a Chinese, we should keep our own culture identity instead of Americanized.

Although the relationship between race and depression is complex, depression affects all races, all ethnic and geographic locations as well as all age groups. The prevalence of depression in African Americans is controversial, due to the paucity of research. The deficit in the knowledge and skills in treating depression in African Americans have not been adequately addressed so far. Inadequate and insufficient data on African Americans contributes to the problems of under diagnoses, misdiagnosis and under treatment of depression.

    The peopling of the Americas has been the subject of extensive genetic, archaeological and linguistic research; however, central questions remain unresolved1–5. One contentious issue is whether the settlement occurred via a single6–8 or multiple streams of migration from Siberia9–15. The pattern of dispersals within the Americas is also poorly understood. To address these questions at higher resolution than was previously possible, we assembled data from 52 Native American and 17 Siberian groups genotyped at 364,470 single nucleotide polymorphisms. We show that Native Americans descend from at least three streams of Asian gene flow. Most descend entirely from a single ancestral population that we call “First American”. However, speakers of Eskimo-Aleut languages from the Arctic inherit almost half their ancestry from a second stream of Asian gene flow, and the Na-Dene-speaking Chipewyan from Canada inherit roughly one-tenth of their ancestry from a third stream. We show that the initial peopling followed a southward expansion facilitated by the coast, with sequential population splits and little gene flow after divergence, especially in South America. A major exception is in Chibchan-speakers on both sides of the Panama Isthmus, who have ancestry from both North and South America. PMID:22801491

    American shad Alosa sapidissima from the Hudson River, New York, were introduced into the Sacramento River, California, in 1871 and were first observed in the Columbia River in 1876. American shad returns to the Columbia River increased greatly between 1960 and 1990, and recently 2-4 million adults have been counted per year at Bonneville Dam, Oregon and Washington State (river kilometer 235). The total return of American shad is likely much higher than this dam count. Returning adults migrate as far as 600 km up the Columbia and Snake rivers, passing as many as eight large hydroelectric dams. Spawning occurs primarily in the lower river and in several large reservoirs. A small sample found returning adults were 2-6 years old and about one-third of adults were repeat spawners. Larval American shad are abundant in plankton and in the nearshore zone. Juvenile American shad occur throughout the water column during night, but school near the bottom or inshore during day. Juveniles consume a variety of zooplankton, but cyclopoid copepods were 86% of the diet by mass. Juveniles emigrate from the river from August through December. Annual exploitation of American shad by commercial and recreational fisheries combined is near 9% of the total count at Bonneville Dam. The success of American shad in the Columbia River is likely related to successful passage at dams, good spawning and rearing habitats, and low exploitation. The role of American shad within the aquatic community is poorly understood. We speculate that juveniles could alter the zooplankton community and may supplement the diet of resident predators. Data, however, are lacking or sparse in some areas, and more information is needed on the role of larval and juvenile American shad in the food web, factors limiting adult returns, ocean distribution of adults, and interactions between American shad and endangered or threatened salmonids throughout the river. ?? 2003 by the American Fisheries Society.

  9. Passage of American shad: paradigms and realities

    Science.gov (United States)

    Haro, Alex; Castro-Santos, Theodore

    2012-01-01

    Despite more than 250 years of development, the passage of American shad Alosa sapidissima at dams and other barriers frequently remains problematic. Few improvements in design based on knowledge of the swimming, schooling, and migratory behaviors of American shad have been incorporated into passage structures. Large-scale technical fishways designed for the passage of adult salmonids on the Columbia River have been presumed to have good performance for American shad but have never been rigorously evaluated for this species. Similar but smaller fishway designs on the East Coast frequently have poor performance. Provision of effective downstream passage for both juvenile and postspawning adult American shad has been given little consideration in most passage projects. Ways to attract and guide American shad to both fishway entrances and downstream bypasses remain marginally understood. The historical development of passage structures for American shad has resulted in assumptions and paradigms about American shad behavior and passage that are frequently unsubstantiated by supporting data or appropriate experimentation. We propose that many of these assumptions and paradigms are either unfounded or invalid and that significant improvements to American shad upstream and downstream passage can be made via a sequential program of behavioral experimentation, application of experimental results to the physical and hydraulic design of new structures, and controlled tests of large-scale prototype structures in the laboratory and field.

  4. The American Turners: their past and present

    Directory of Open Access Journals (Sweden)

    2015-06-01

    Full Text Available The United States has been a nation of immigrants, which is reflected by its multicultural society. Different immigrant groups helped shape the American society through their cultures and traditions. One group was the Germans; they represented a unique and forceful current in the stream of immigration to the United States. In their cultural luggage the German immigrant brought their physical culture to North America, Turnen which was organised in clubs or so-called Turnvereine. The American turner movement has its origin in the mid 19th century, and it is still organised on a national level, since the 1930s under the name American Turners. This article summarises the history of the German-American turner movement until the 1990s, and will also relate to various stages of Americanization within this movement.

  5. Asian American Evangelicals in Multiracial Church Ministry

    Directory of Open Access Journals (Sweden)

    Kathleen Garces-Foley

    2013-04-01

    Full Text Available Since the 1990s, evangelical efforts to create multiracial churches (MRCs have grown exponentially. This article analyzes the experiences of Asian American evangelical ministers leading MRCs. Through interviews we explore how Asian American evangelicals came to be involved in MRC-ministry and how they approach issues of racial diversity in this context. We compare the racial attitudes of Asian American evangelical ministers leading MRCs with those of White and Black evangelicals delineated in Emerson and Smith’s Divide by Faith. Rather than conform to the colorblind approach of many White evangelicals, the majority of our respondents utilize structural explanations for social inequality and promote a colorconscious approach to diversity. We conclude that Asian American evangelicals utilize a unique framework for MRC-ministry, what we call a ‘racialized multiculturalism,’ that has much to offer American evangelicalism.

  6. American marsupials chromosomes: why study them?

    Directory of Open Access Journals (Sweden)

    Marta Svartman

    2009-01-01

    Full Text Available Marsupials, one of the three main groups of mammals, are only found in Australia and in the American continent. Studies performed in Australian marsupials have demonstrated the great potential provided by the group for the understanding of basic genetic mechanisms and chromosome evolution in mammals. Genetic studies in American marsupials are relatively scarce and cytogenetic data of most species are restricted to karyotype descriptions, usually without banding patterns. Nevertheless, the first marsupial genome sequenced was that of Monodelphis domestica, a South American species. The knowledge about mammalian genome evolution and function that resulted from studies on M. domestica is in sharp contrast with the lack of genetic data on most American marsupial species. Here, we present an overview of the chromosome studies performed in marsupials with emphasis on the South American species.

    Energy Technology Data Exchange (ETDEWEB)

    Lucet, G.

    2007-07-01

    Meso american archaeology works with large amounts of disperse and diverse information, thus the importance of including new methods that optimise the acquisition, conservation, retrieval, and analysis of data to generate knowledge more efficiently and create a better understanding of history. Further, this information --which includes texts, coordinates, raster graphs, and vector graphs-- comes from a considerable geographical area --parts of Mexico, Nicaragua, Honduras and Costa Rica as well as Guatemala, El Salvador and Belize-- is constantly expanding. This information includes elements like shards, buildings, mural paintings, high and low reliefs, topography, maps, and information about the fauna and soil. Grid computing offers a solution to handle all this information: it respects researchers' need for independence while supplying a platform to share, process and compare the data obtained. Additionally, the Grid can enhance space-time analyses with remote visualisation techniques that can, in turn, incorporate geographical information systems and virtual reality. (Author)

    Nollet, Kenneth E

    2011-01-01

    A magnitude 9.0 earthquake and tsunami originating off the east coast of Japan triggered the explosive release of radioactive isotopes from one of four nuclear power plants in the affected area. This event has been compared with the 1986 nuclear accident at Chernobyl, the 1945 atomic bombing of Hiroshima and Nagasaki, and the intervening era of atmospheric nuclear weapons testing. The credibility of any comparison depends on the source, for which reason various specialists were invited to address an audience of media, healthcare, and disaster response professionals on July 18, 2011 in Fukushima City, Fukushima Prefecture. This article is based on a presentation given July 18, and interprets the Fukushima nuclear crisis from the perspective of an American doctor who grew up downwind of an atomic bomb test site, and who now works at Fukushima Medical University.

    As an addendum to J. Urrutia Fucugauchi's (Eos, 63, June 8, 1982, p. 529) excellent analysis of why things go wrong in Latin American geophysics, I submit that funds in whatever form are not the only answer. In Mexico over the past decade there has been a reasonable availability of funds, yet no dramatic increase in the quality or quantity of geophysical research was detected. Graduate scholarships have even gone begging for applicants in the earth sciences!Leadership is the big problem. National plans and forecasts for science and technology continue to ignore this central fact. They want to generate hundreds, nay thousands, of middle-level scientists while providing no incentive for excellence. As others have found out long before us, this approach is doomed from the start.

    Blows to the head damage the brain. American football is a contact/collision sport that produces many injuries, including to the brain. Football has many supporters who cite important redeeming characteristics of the activity. Public attention to the hazards of children and adults playing football has heightend recently due to many new scientific discoveries, not least of which is the frequency with which players are seriously harmed and do not recover. It is now incumbent on all interested parties to invent and implement far better safety practices, equipment, rules, and processes or the sport must cease to exist in its current form. This paper presents several safety proposals for consideration and study. PMID:27284499

  17. Excerpt from Dead Stars: American and Philippine Literary Perspectives on the American Colonization of the Philippines

    Directory of Open Access Journals (Sweden)

    Jennifer M. McMahon

    2011-12-01

    Full Text Available Dead Stars: American and Philippine Literary Perspectives on the American Colonization of the Philippines examines the American colonization of the Philippines from three distinct but related literary perspectives. The first is the reaction of anti-imperialist American writers Mark Twain, W. E. B. Du Bois, and William James to America’s first foray into the role of colonizer and how their varied essays, letters, and speeches provide an incisive delineation of fundamental conflicts in American identity at the turn of the twentieth century. The book then analyzes how these same conflicts surface in the colonial regime’s use of American literature as a tool to inculcate American values in the colonial educational system. Finally, Dead Stars considers the way three early and important Filipino writers—Paz Marquez Benitez, Maximo Kalaw, and Juan C. Laya—interpret and represent these same tensions in their fiction.

  18. Suicide among Arab-Americans.

    Directory of Open Access Journals (Sweden)

    Abdulrahman M El-Sayed

    Full Text Available BACKGROUND: Arab-American (AA populations in the US are exposed to discrimination and acculturative stress-two factors that have been associated with higher suicide risk. However, prior work suggests that socially oriented norms and behaviors, which characterize recent immigrant ethnic groups, may be protective against suicide risk. Here we explored suicide rates and their determinants among AAs in Michigan, the state with the largest proportion of AAs in the US. METHODOLOGY/PRINCIPAL FINDINGS: ICD-9/10 underlying cause of death codes were used to identify suicide deaths from among all deaths in Michigan between 1990 and 2007. Data from the 2000 U.S. Census were collected for population denominators. Age-adjusted suicide rates among AAs and non-ethnic whites were calculated by gender using the direct method of standardization. We also stratified by residence inside or outside of Wayne County (WC, the county with the largest AA population in the state. Suicide rates were 25.10 per 100,000 per year among men and 6.40 per 100,000 per year among women in Michigan from 1990 to 2007. AA men had a 51% lower suicide rate and AA women had a 33% lower rate than non-ethnic white men and women, respectively. The suicide rate among AA men in WC was 29% lower than in all other counties, while the rate among AA women in WC was 20% lower than in all other counties. Among non-ethnic whites, the suicide rate in WC was higher compared to all other counties among both men (12% and women (16%. CONCLUSIONS/SIGNIFICANCE: Suicide rates were higher among non-ethnic white men and women compared to AA men and women in both contexts. Arab ethnicity may protect against suicide in both sexes, but more so among men. Additionally, ethnic density may protect against suicide among Arab-Americans.

It must be added that for most low and middle-income countries, deficient strategies of primary healthcare are the major obstacles for blood pressure control. Furthermore, the epidemiology of hypertension and related diseases, healthcare resources and priorities, the socioeconomic status of the population vary considerably in different countries and in different regions of individual countries. Considering the low rates of blood pressure control achieved in Latin America and the benefits that can be expected from an improved control, it was decided to invite specialists from different Latin American countries to analyze the regional situation and to provide a consensus document on detection, evaluation and treatment of hypertension that may prove to be cost-utility adequate. The recommendations here included are the result of preparatory documents by invited experts and a subsequent very active debate by different discussion panels, held during a 2-day sessions in Asuncion, Paraguay, in May 2008. Finally, in order to improve clinical practice, the publication of the guidelines should be followed by implementation of effective interventions capable of overcoming barriers (cognitive, behavioral and affective) preventing attitude changes in both physicians and patients.

    With the development of globalization and gradual intensification of mutual dependence of the world,"hard power" which indudes economic and military strength is no longer the primary consideration for many countries.They tend to pay more attention to the attractiveness of their "soft power",which includes values,life style,ideology and so forth.Just as Joseph S.Ny,the famous professor of Harvard who puts forward the concept of soft power,says,"only by widespread communication and diffusion can a country reinforces its soft power".This is mass media's function.Since the 1990s,tens of thousands cultural products brought in from America are exported to foreign countries,including popular music,films,TV programs,magazines,books and so forth.By making advantage of its monopoly position in media circle,the United States pursues cultural hegemonism and expands its popttlar culture all over the world.This thesis takes a general view of the great advantages of America multi-national media groups and how they push forward the American popular culture all over the world.

  3. Differences in the tumor microenvironment between African-American and European-American breast cancer patients.

    Damali N Martin

    Full Text Available BACKGROUND: African-American breast cancer patients experience higher mortality rates than European-American patients despite having a lower incidence of the disease. We tested the hypothesis that intrinsic differences in the tumor biology may contribute to this cancer health disparity. METHODS AND RESULTS: Using laser capture microdissection, we examined genome-wide mRNA expression specific to tumor epithelium and tumor stroma in 18 African-American and 17 European-American patients. Numerous genes were differentially expressed between these two patient groups and a two-gene signature in the tumor epithelium distinguished between them. To identify the biological processes in tumors that are different by race/ethnicity, Gene Ontology and disease association analyses were performed. Several biological processes were identified which may contribute to enhanced disease aggressiveness in African-American patients, including angiogenesis and chemotaxis. African-American tumors also contained a prominent interferon signature. The role of angiogenesis in the tumor biology of African-Americans was further investigated by examining the extent of vascularization and macrophage infiltration in an expanded set of 248 breast tumors. Immunohistochemistry revealed that microvessel density and macrophage infiltration is higher in tumors of African-Americans than in tumors of European-Americans. Lastly, using an in silico approach, we explored the potential of tailored treatment options for African-American patients based on their gene expression profile. This exploratory approach generated lists of therapeutics that may have specific antagonistic activity against tumors of African-American patients, e.g., sirolimus, resveratrol, and chlorpromazine in estrogen receptor-negative tumors. CONCLUSIONS: The gene expression profiles of breast tumors indicate that differences in tumor biology may exist between African-American and European-American patients beyond the

  4. The ethnic context of Mexican American fertility.

    Researchers analyzed 1980 data on 9954 ever married Mexican American 20-44 year old women living in metropolitan statistical areas (MSA) in the US with at least 50 Mexican Americans to test a multilevel model of Mexican American fertility. The model included percent Mexican American and measures of ethnic cultural integration and constraints in labor market opportunities. The index of ethnic cultural context consisted of percent of Mexican Americans in the MSA who were born in Mexico, immigrated to the US since 1970, and did not speak English well or not at all. Overall it did not have any effect on recent births (at least 1 birth in past 3 years). Yet it did increase the probability of other births among =or30 year old women who already had at least 4 children (p.05). Nevertheless only 13.4% of =or30 year old women with at least 4 children had another child in the last 3 years, thus the effect on overall Mexican American fertility was minimal. Limited economic opportunities had a significant positive effect on fertility for 30 year old women (p.05) as indicated by the unemployment ratio (unemployment rate of Mexican American females/unemployment rate of White females). The greatest effect of limited economic opportunities was that they induced these women to have a 3rd child. Further percent Mexican American also influenced recent births for 30 year old women even after the researchers included the direct measures of cultural and economic context in their analyses (p.05). Like the measure of economic context, the pattern of significance of percent Mexican American held true across age and parity. Thus economic limitations were more likely to explain the effect of group size on fertility than were cultural patterns. PMID:12317290

    2016-01-01

    This study examined the use of preventive health services among Korean American adults. Data were drawn from a cross-sectional survey of 212 Korean Americans in the Chicago, Illinois, metropolitan area. Guided by the Andersen's behavioral model, the authors examined whether predisposing (age, gender, marital status, household size, education), enabling (income, health insurance, English proficiency, citizenship, social network), and need (health status) factors are predictive of Korean Americans' preventive health services utilization. A binomial logistic regression showed that younger age, male, noncitizen, low income, no insurance, a larger family network, and better perceived health were associated with decreased odds of using preventive health services.

    Morelen, Diana; Thomassin, Kristel

    2013-06-01

    The current review paper summarizes the literature on parental emotion socialization in ethnically diverse families in the United States. Models of emotion socialization have been primarily developed using samples of European American parents and children. As such, current categorizations of "adaptive" and "maladaptive" emotion socialization practices may not be applicable to individuals from different ethnic backgrounds. The review examines current models of emotion socialization, with particular attention paid to the demographic breakdown of the studies used to develop these models. Additionally, the review highlights studies examining emotion socialization practices in African American, Asian American, and Latin American families. The review is synthesized with summarizing themes of similarities and differences across ethnic groups, and implications for culturally sensitive research and practice are discussed.

    Full Text Available PURPOSE: To establish current definition, classification and staging, and to develop diagnosis and treatment recommendations for ocular allergy, by using Delphi approach. METHODS: Ten Latin American experts on ocular allergy participated in a 4-round Delphi panel approach. Four surveys were constructed and answered by panelists. A two-thirds majority was defined as consensus. Definition, classification, staging and diagnosis and treatment recommendations were the main outcomes. RESULTS: "Ocular allergy" was proposed as the general term to describe ocular allergic diseases. Consensus regarding classification was not reached. Signs and symptoms were considered extremely important for the diagnosis. It was consensus that a staging system should be proposed based on the disease severity. Environmental control, avoidance of allergens and the use of artificial tears were recommended as first line treatment. The secondary treatment should include topical anti-histamines, mast cell stabilizers and multi actions drugs. Topical non-steroidal anti-inflammatory and vasoconstrictors were not recommended. Topical corticosteroids were recommended as third line of treatment for the most severe keratoconjunctivitis. Consensus was not reached regarding the use of systemic corticosteroids or immunosuppressant. Surgical approach and unconventional treatments were not recommended as routine. CONCLUSION: The task of creating guidelines for ocular allergies showed to be very complex. Many controversial topics remain unsolved. A larger consensus including experts from different groups around the world may be needed to further improve the current recommendations for several aspects of ocular allergy.

    1981-07-01

    Prospects for North American tidal power electrical generation are reviewed. Studies by the US Army Corps of Engineers of 90 possible generation schemes in Cobscook Bay, ME, indicated that maximum power generation rather than dependable capacity was the most economic method. Construction cost estimates for 15 MW bulb units in a single effect mode from basin to the sea are provided; five projects were considered ranging from 110-160 MW. Additional tidal power installations are examined for: Half-Moon Cove, ME (12 MW, 18 ft tide); Cook Inlet, AK, which is shown to pose severe environmental and engineering problems due to fish migration, earthquake hazards, and 300 ft deep silt deposits; and the Bay of Fundy, Canada. This last has a 17.8 MW plant under construction in a 29 ft maximum tide area. Other tidal projects of the Maritime Provinces are reviewed, and it is noted that previous economic evaluations based on an oil price of $16/barrel are in need of revision.

  14. How to Assess American Democracy?

    Full Text Available This article proposes a framework to evaluate the functioning of American democracy and to suggest, accordingly, suitable reforms. Reform, literally, means to form again, to reshape and restructure, sometimes to return to basic values that had been lost and sometimes to pursue newly emerging ones. It implies an improvement over the status quo in pursuit of some objective, and it is the question of goals and objectives that raise problems. This article’s main findings suggest that there are seven general values or criteria by which government and the political process – and therefore reform proposals – are to be evaluated. Governmental institutions and processes above all must be (1 effective, implying that its actions must be determined by a process of (2 reasoned and fair deliberation and judgment and that its operations should be (3 efficient. At the same time, government must be controlled and limited, leading to the criteria that apply to the citizenry: (4 responsiveness, (5 representativeness, (6 accountability and (7 participation. Any government that meets these criteria is very likely to be perceived as fair and legitimate by the governed, and is likely to be safe and protect liberties.

  15. Drinker prototypes in American society.

    Klein, H; Pittman, D J

    1990-01-01

    Based on a national probability sample of 2,401 Americans age 21 and over (1,069 of whom were deemed "drinkers" on the basis of having consumed at least one alcoholic beverage in the past 7 days), this study develops profiles of the drinker and heavier drinking prototypes for beer, distilled spirits, wine, and wine cooler drinkers. Both beer-drinking prototypes are mainly composed of less well-educated males who drink beer in circumstances unconnected with any mealtime setting. Wine drinkers are more often women (although the heavy drinking prototype is more likely to be a man), usually with education at or beyond the "some college" level, who typically drink wine in moderation with a meal such as dinner. Both prototypes of the distilled spirits drinkers are likely to be men, age 45 or over, who are not currently married, who usually drink in a bar, before a meal, when they feel somewhat happy or calm. Wine cooler drinkers are much more heterogeneous, and hence less distinguishable than the other drinking prototypes. The heavier wine cooler drinker, however, is likely to be single, with 12 or 13 years of schooling. This person usually drinks when feeling very stimulated, very happy, very romantic, or else very bored, and often does so at bars or in friends' homes.

  16. Drug testing in American schools

    Directory of Open Access Journals (Sweden)

    C.J. Russo

    2003-08-01

    Full Text Available As the use of illegal drugs has reached epidemic proportions in schools, educational leaders in the United States have turned to drug testing in attempting to maintain learner discipline. To this end, the United States Supreme Court has addressed the issue twice in the past eight years. In 1995, the Court permitted drug testing in Acton v. Vernonia School District 47J. More recently, in Board of Education of Independent School District No. 92 of Pottawatomie v. Earls (2002, the Court upheld suspicionless drug testing of learners who wished to participate in extracurricular activities. Even though drug testing has yet to emerge as an issue in South Africa, Earls is significant for educational leaders and policy makers in South Africa since it involves concerns under the National Policy on Privacy. More specifically, under Items 20 and 21 of the South African National Policy on the Management of Drug Abuse (SA, 1996b searches and drug testing should only be used where there is reasonable suspicion, the same standard applied by American courts. However, unlike the United States, the South African policy prohibits random searches and/or drug testing. Thus, due to constitutional and educational issues that drug testing raises, a timely discussion of this matter should be of interest to educational leaders and policy makers in South Africa.

    Chalupnicki, Marc A.; Dittman, Dawn E.

    2016-01-01

    Accurate expedient species identification of deceased sturgeon (Acipenseridae) when external physical characteristic analysis is inconclusive has become a high priority due to the endangered or threatened status of sturgeon species around the world. Examination of otoliths has provided useful information to aid in population management, age and size-class analysis, understanding predator–prey interactions, and archeological research in other fish species. The relationship between otolith characteristics and sturgeon species has remained unknown. Therefore, we analyzed the shape of otoliths from the eight species of sturgeon found in North America to test the utility of otolith characteristic morphology in species identification. There were distinct differences in the size and shape of the otoliths between species of sturgeon with little shape variation among individuals of the same species. The relationship between otolith length axes was linear, and most of the variability was explained by a Log (axis + 1) transformation of the x and y axes (r2 = 0.8983) using the equation y = 0.73x + 0.0612. Images of otoliths from all eight North American species are presented to assist in the identification process.

    2016-01-01

    African American adolescents report more depressive symptoms than their European American peers, but the reasons for these differences are poorly understood. This study examines whether risk factors in individual, family, school, and community domains explain these differences. African American and European American adolescents participating in the Birmingham Youth Violence Study (N = 594; mean age 13.2 years) reported on their depressive symptoms, pubertal development, aggressive and delinquent behavior, connectedness to school, witnessing violence, and poor parenting. Primary caregivers provided information on family income and their education level, marital status, and depression, and the adolescents' academic performance. African American adolescents reported more depressive symptoms than European American participants. Family socioeconomic factors reduced this difference by 29%; all risk factors reduced it by 88%. Adolescents' exposure to violence, antisocial behavior, and low school connectedness, as well as lower parental education and parenting quality, emerged as significant mediators of the group differences in depressive symptoms.

    In this case-control study we determined whether dietary differences underlie some of the ethnic and sex differences in US lung cancer rates. We examined the relationship between diet and lung cancer development in 137 lung cancer cases (93 African Americans and 44 Mexican Americans) and 187 controls (78 African Americans and 109 Mexican Americans). Cases reported a higher daily mean total fat intake (p fruits (p = 0.02). Ethnic differences in diet were also observed: Mexican Americans consumed less total fat (p fruits (p lung cancer risk (p fruit consumption and lung cancer risk (p = 0.05). In conclusion, our findings support the hypothesis that diet, particularly high fat consumption and low fruit and vegetable consumption, contributes (independent of cigarette smoking) to the excess lung cancer risk in African-American men, who have the highest lung cancer rates in the United States.

    Broome, Barbara; Broome, Rochelle

    2007-04-01

    There are an estimated 4.1 million people who are classified as American Indian and Alaska Native alone or in combination with one or more other races. This racial group composes 1.5% of the total U.S. population. The leading causes of illness and death among American Indians are heart disease, cancer, unintentional injuries (accidents), diabetes, and stroke. American Indians also have a high prevalence of obesity, chronic renal failure, alcoholism, and are at increased risk for mental health issues and suicide. In an effort to build a trusted relationship with these patients and become an active participant in their care, the health care provider must demonstrate respect for the traditions of the American Indian.

  5. The persistence of American Indian health disparities.

    Science.gov (United States)

    Jones, David S

    2006-12-01

    Disparities in health status between American Indians and other groups in the United States have persisted throughout the 500 years since Europeans arrived in the Americas. Colonists, traders, missionaries, soldiers, physicians, and government officials have struggled to explain these disparities, invoking a wide range of possible causes. American Indians joined these debates, often suggesting different explanations. Europeans and Americans also struggled to respond to the disparities, sometimes working to relieve them, sometimes taking advantage of the ill health of American Indians. Economic and political interests have always affected both explanations of health disparities and responses to them, influencing which explanations were emphasized and which interventions were pursued. Tensions also appear in ongoing debates about the contributions of genetic and socioeconomic forces to the pervasive health disparities. Understanding how these economic and political forces have operated historically can explain both the persistence of the health disparities and the controversies that surround them.

  7. The Contributions of Immigrants to American Culture.

    Science.gov (United States)

    Hirschman, Charles

    2013-01-01

    The standard account of American immigration focuses on the acculturation and assimilation of immigrants and their children to American society. This analysis typically ignores the significant contributions of immigrants to the creation of American culture through the performing arts, sciences, and other cultural pursuits. Immigrants and their children are not born with more creative talents than native-born citizens, but their selectivity and marginality may have pushed and pulled those with ability into high-risk career paths that reward creative work. The presence of large numbers of talented immigrants in Hollywood, academia, and the high-tech industries has pushed American institutions to be more meritocratic and open to innovation than they would be otherwise.

  15. Colorectal Cancer in African Americans: An Update.

    Science.gov (United States)

    Williams, Renee; White, Pascale; Nieto, Jose; Vieira, Dorice; Francois, Fritz; Hamilton, Frank

    2016-01-01

    This review is an update to the American College of Gastroenterology (ACG) Committee on Minority Affairs and Cultural Diversity's paper on colorectal cancer (CRC) in African Americans published in 2005. Over the past 10 years, the incidence and mortality rates of CRC in the United States has steadily declined. However, reductions have been strikingly much slower among African Americans who continue to have the highest rate of mortality and lowest survival when compared with all other racial groups. The reasons for the health disparities are multifactorial and encompass physician and patient barriers. Patient factors that contribute to disparities include poor knowledge of benefits of CRC screening, limited access to health care, insurance status along with fear and anxiety. Physician factors include lack of knowledge of screening guidelines along with disparate recommendations for screening. Earlier screening has been recommended as an effective strategy to decrease observed disparities; currently the ACG and American Society of Gastrointestinal Endoscopists recommend CRC screening in African Americans to begin at age 45. Despite the decline in CRC deaths in all racial and ethnic groups, there still exists a significant burden of CRC in African Americans, thus other strategies including educational outreach for health care providers and patients and the utilization of patient navigation systems emphasizing the importance of screening are necessary. These strategies have been piloted in both local communities and Statewide resulting in notable significant decreases in observed disparities. PMID:27467183

  16. The North American electricity markets

    International Nuclear Information System (INIS)

    The wide ranging changes that will drive the evolution of the North American electricity industry in the future are discussed. Deregulation and the advent of competition in both the United States and Canada are the principal forces that will change the shape of the electricity market, bringing new players and new forms of doing business into the marketplace. A review of the current state of the business shows that especially in the United States where deregulation began earlier than in Canada, independent generators already constitute a multi-billion dollar industry. Non-utility generation capacity is about seven per cent of total U.S. capacity and accounts for about 10 per cent of total U. S. electricity supply, including imports. Examples from other industries clearly show that restructuring and the breakup of vertically integrated industries could be accomplished much faster than anticipated, that a decrease in prices followed rapidly as products became more like commodities, and that decreasing prices fostered product differentiation and competition. Major legislation affecting the electric power industry in the U.S. and Canada (U.S. National Energy Policy Act 1992, Alberta Electric Utilities Act 1995, Ontario Energy Competition Act 1998) decreeing open access transmission, unbundling of generation, transmission and ancillary services, and promoting competition, and the impacts of these legislative actions are also reviewed. The most visible impact is the explosion that can be seen in power marketing and energy trading on a scale unimaginable only a few short years ago, where the total volume of trade may be worth multiples of the value of the underlying commodity. At the same time, there is concern about the reliability of the system, and thus making it imperative to find new ways to manage reliability. Various suggestions are made as to how increased reliability of supply could be achieved by better management, new standards and better enforcement of
