    Full Text Available The Danube Soya Association is an international, voluntary, non-profit, non-governmental association promoting sustainable and GMO**-free soya production along the Danube River Basin – from Switzerland to the Black Sea. Founded in 2012 the association counts today more than 200 members from the whole value chain and civil society in 16 European countries. The members share the vision of a protein transition towards more European and more sustainable protein sources for food and feed. The Danube Area is an area of large potential agricultural surpluses and Danube Soya promotes the idea of using these surpluses to replace a part of the imported soya. The goals of the association are to increase value-added in the rural economies of Central Eastern Europe, promote European cooperation as well as a production of constant and sustainable local soya sources. The Danube Soya Association runs a certification scheme that reaches from soya seeds all the way to final products, which can be labelled with the consumer label “Fed with Danube Soya” (for animal products and “Danube Soya” (for soya food products. Together with its partners, the Danube Soya Association implements and supports dissemination and research projects on different topics.

    Full Text Available This study was carried out to obtain the optimum conditions necessary for the process of soya protein hydrolysis by using hydrochloric acid (as a chemical catalyst instead of the papain enzyme (as a biological catalyst, for the production of soya peptone. These conditions are implemented to test the effect of the variables of the process of hydrolysis on the nature and quality of the product. The production of soya peptone was studied for their importance in the process of preparing and producing the culture media used in medical and microbiological laboratories. The process of production of soya peptone includes four main stages:•Preparing the defatted soya flour, firstly.•The soya protein hydrolysis, secondly. •Purifying the product, thirdly , and then, •Drying the product, finally. By following the procedure of the present study, the optimum conditions for the process of soya proteins hydrolysis have been reached in present study are:•Optimum concentration for the hydrochloric acid solution is 1N.•Optimum hydrolysis process temperature ranged between 50-53C. •Optimum period of hydrolysis time ranged between 17.189-19.97 hr. The productivity of soya peptone was 38.071%, by following the procedure and the optimum production conditions of the present study.

  4. Properties of soya milk and tofu prepared with gamma-irradiated soya beans

    International Nuclear Information System (INIS)

    Soya beans (Glycine max) 'hwang keum' were gamma-irradiated at dose levels of 0, 2 5, 5, 10 and 20 kGy and the effects of the irradiated soya beans on soya milk and tofu properties were studied. An irradiation dose of 5 kGy caused an increase in yield of soya milk and tofu while having very little effect on their quality. The properties of tofu prepared with the soya beans irradiated at 2.5-5 kGy showed no significant difference from the non-irradiated control. However, at higher doses (10-20 kGy), decreases in yield, water holding capacity and sag value of tofu were observed. Compared with the non-irradiated control, hardness and fracturability in the texture of tofu were both significantly increased when the soya bean had been irradiated at 10-20 kGy, while cohesiveness and adhesiveness decreased. The changes in color values of soya milk and tofu were pronounced at 20 kGy

    We define CoVaR as the value at risk (VaR) of financial institutions conditional on other institutions being in distress. The increase of CoVaR relative to VaR measures spillover risk among institutions. We estimate CoVaR using quantile regressions and document significant CoVaR increases among financial institutions. We identify six risk factors that allow institutions to offload tail risk and show that such hedging reduces the wedge between CoVaR and VaR. We argue that financial institution...

  9. [Soya isoflavones and evidences on cardiovascular protection].

    Science.gov (United States)

    González Cañete, Natalia; Durán Agüero, Samuel

    2014-01-01

    Soya isoflavones represent a group of non-nutritive, bioactive compounds, of non-steroidal phenolic nature that are present in soy bean and derived foods. They share with other compounds the capacity of binding to estrogenic receptors from different cells and tissues so that they may act as phytoestrogens. The current interest in these compounds comes from the knowledge that in Asian populations with high levels of their consumption the prevalence of cancer and cardiovascular disease is lower, as compared to the Western countries populations. This cardiovascular benefit would be the result not only of the modulation of plasma lipids, which is a widely studied mechanism. This paper reviews the published evidence about the beneficial effects of soya isoflavones and the different mechanisms of action that would benefit cardiovascular health and that surpass the mechanisms traditionally approached such as the modulation of plasma lipids, and that implicate the regulation of cellular and enzymatic functions in situations such as inflammation, thrombosis, and atherosclerotic progression.

    The expansion and intensification of soya bean agriculture in southeastern Amazonia can alter watershed hydrology and biogeochemistry by changing the land cover, water balance and nutrient inputs. Several new insights on the responses of watershed hydrology and biogeochemistry to deforestation in Mato Grosso have emerged from recent intensive field campaigns in this region. Because of reduced evapotranspiration, total water export increases threefold to fourfold in soya bean watersheds compared with forest. However, the deep and highly permeable soils on the broad plateaus on which much of the soya bean cultivation has expanded buffer small soya bean watersheds against increased stormflows. Concentrations of nitrate and phosphate do not differ between forest or soya bean watersheds because fixation of phosphorus fertilizer by iron and aluminium oxides and anion exchange of nitrate in deep soils restrict nutrient movement. Despite resistance to biogeochemical change, streams in soya bean watersheds have higher temperatures caused by impoundments and reduction of bordering riparian forest. In larger rivers, increased water flow, current velocities and sediment flux following deforestation can reshape stream morphology, suggesting that cumulative impacts of deforestation in small watersheds will occur at larger scales.

    Soya, cultivated for more than 3000 years, is both a drug and a food product. It has numerous nutritional benefits, given by its content of isoflavones, essential amino acids, fibers, poly-unsaturated fatty acids, vitamins and minerals. The use of soy reduces the risk of cardiovascular diseases: it has an antioxidant effect, reduces cholesterol levels and modulates the endothelial function; the soy foods, rich in isoflavones, reduce the risk of breast cancer; men with heredocolateral cancer antecedents or with minimal increase of prostate antigen must consider the consumption of soy and soy foods. Soy and soy foods play an important role in reducing the incidence of osteoporosis and controlling the pre- and postmenopausal symptoms; the soy ingestion has benefic metabolic effects in patients with Diabetes Mellitus and overweight. Taking into consideration the nutritional profile of soy, the nutritionists should encourage the population to consume more soy and soy foods. Nevertheless, long term studies are needed to discover a possible "dark side" of soy consumption. Among the most popular soy foods we mention: soymilk, soy cheese (tofu), soy meat (pie, salami, textured soy in granule form). Most of the products are soy flour derivatives, while tofu is obtained by curdling soymilk. PMID:17966452

    While allergic reactions to soya are increasingly investigated, the normal immune response to ingested soya is scarcely described. In the present study, we wanted to characterise the soya-specific immune response in healthy mice ingesting soya protein. Mice fed a soya-containing diet (F0) and mice of the first (F1) and second (F2) offspring generation bred on a soya protein-free diet were used either directly or were transferred between the soya-containing and soya protein-free diet during pregnancy or neonatal life. The mice were compared as to levels of naturally occurring specific antibodies analysed by ELISA, and to the presence of oral tolerance detected as a suppressed antibody and cell-proliferation response upon immunisation with soya protein. F0 mice generated soya-specific antibodies, while oral tolerance to the same soya proteins was also clearly induced. When F0 dams were transferred to soya protein-free feed before mating, the F1 and F2 offspring generations showed no significantly different response, indicating that soya-specific immune components were not maternally transmitted. However, the ingestion of dietary soya protein by F1 mice during late pregnancy and lactation caused a lasting antibody response in the offspring, but in this case in the absence of oral tolerance. This indicates that, under certain conditions, factors involved in spontaneous antibody production can be transmitted from mother to offspring. Understanding the immune response to soya protein ingested under healthy conditions is important in the assessment of adverse effects of soya protein and in the use of animal allergy models. The present results add to this understanding. PMID:15137924

    Full Text Available Abstract. In connection with the increasing number of allergic diseases in Russia and in the world, the exogenic factor responsible for the development of food allergy in children have been discussed. The main types of alimentary allergens have been determined; their biochemical features, as well as aggravation of the food allergy clinical symptoms to the extent of anaphylaxis, have been reported. With the development of genetic engineering food products, the special attention has been paid to hypersensitivity to soya bean proteins. The major and minor allergens of soya beans, their homologues in other vegetable allergens, e.g. birch pollen allergens, have been described. (Med. Immunol., 2005, vol.7, № 1, pp. 15520

    Soya-based infant formulas (SIF) containing soya flour were introduced almost 100 years ago. Modern soya formulas are used in allergy/intolerance to cows' milk-based formulas (CMF), post-infectious diarrhoea, lactose intolerance and galactosaemia, as a vegan human milk (HM) substitute, etc. The safety of SIF is still debated. In the present study, we reviewed the safety of SIF in relation to anthropometric growth, bone health (bone mineral content), immunity, cognition, and reproductive and endocrine functions. The present review includes cross-sectional, case-control, cohort studies or clinical trials that were carried out in children fed SIF compared with those fed other types of infant formulas and that measured safety. The databases that were searched included PubMed (1909 to July 2013), Embase (1988 to May 2013), LILACS (1990 to May 2011), ARTEMISA (13th edition, December 2012), Cochrane controlled trials register, Bandolier and DARE using the Cochrane methodology. Wherever possible, a meta-analysis was carried out. We found that the anthropometric patterns of children fed SIF were similar to those of children fed CMF or HM. Despite the high levels of phytates and aluminium in SIF, Hb, serum protein, Zn and Ca concentrations and bone mineral content were found to be similar to those of children fed CMF or HM. We also found the levels of genistein and daidzein to be higher in children fed SIF; however, we did not find strong evidence of a negative effect on reproductive and endocrine functions. Immune measurements and neurocognitive parameters were similar in all the feeding groups. In conclusion, modern SIF are evidence-based safety options to feed children requiring them. The patterns of growth, bone health and metabolic, reproductive, endocrine, immune and neurological functions are similar to those observed in children fed CMF or HM. PMID:24507712

  3. Effect of γ-irradiation on soya bean proteins

    International Nuclear Information System (INIS)

    The properties of soya beans proteins following γ-irradiation (5-20 kGy) were investigated in connection with protein denaturation. Irradiation doses above 10 kGy caused a decrease in 7S and 11S components and an increase in 2S and 15S components (P < 0.05). However, subunit patterns determined by electrophoresis were not changed appreciably over the entire irradiation dose range. In the differential scanning calorimetry thermogram, the denaturation temperatures of 11S and 7S components were not affected by γ-irradiation, while increased irradiation dose caused a decrease in the enthalpy values of 11S and 7S components due to protein denaturation. Changes in the circular dichroism spectra and tryptophan fluorescence intensity (P < 0.05) were observed only at 20 kGy. (author)

    Soya isoflavones, genistein and daidzein, are the focus of numerous studies investigating their potential effects on health and results remain controversial. Bioavailability is clearly a crucial factor influencing their bioefficacy and could explain these discrepancies. This study aimed at assessing: (1) the isoflavone content of sixty-nine European soya-derivative products sold on the French market; (2) the bioavailability of isoflavones comparing supplement with food. Twelve healthy volunteers were recruited in a randomized two-way crossover trial and received 35 mg isoflavones equivalent aglycone either through supplements or through cheese, both containing different patterns of isoflavone conjugates and different daidzein:genistein ratios. A specific ELISA method was used to assess the plasma and urinary concentrations of isoflavones and thus the pharmacokinetic parameters, which were then normalized to mg of each isoflavone ingested. Results showed that the normalized Cmax of daidzein (P = 0.002) and similarly the normalized AUC0 --> infinity and Cmax of genistein (P = 0.002) from soya-based capsules were higher than that from soya-based cheese. In conclusion, this work completes studies on isoflavone bioavailability and presents new data regarding isoflavone concentrations in soya-derivative products. Assuming that isoflavone conjugation patterns do not influence isoflavone bioavailability, this study shows that isoflavones contained in capsules are more bioavailable than those contained in soya-based cheese. Although the supplement is more bioavailable, the relative importance of this is difficult to interpret as there is little evidence that supplements are biologically active in human subjects to date and further studies will be necessary for this specific supplement to prove its efficacy.

  6. Estimation of soya cultivation efficiency in conditions of Belarus lands polluted by radionuclides

    International Nuclear Information System (INIS)

    Production of high-protein soya crop including lands polluted by radionuclides after the Chernobyl accident, causes to the necessity of carrying out research to study the radionuclide transfer into production of this crop. As a result of research the transfer factors of 137Cs and 90Sr from soil into seeds and green mass of various soya varieties have been determined to allow a prediction of radionuclide transfer into production. Limiting densities of radionuclide pollution for moderately improved sod - podzol sandy soils for production of the soya products corresponding of 137Cs and 90Sr content to the national permissible levels are established. Use of the crop in plant cultivation and cattle-breeding branch is accompanied by high energy - conserving effects. Soya products contains high quantity of total energy per kilogram of forage. The most highly energy-conserving forages are waste products of soya processing: an oil cake - up to 87,4 Mj and soil-seed meal up to 79,7 Mj. High profitability of this crop cultivation is provided by production for seeds. It is economically defensible a soya beans cultivation for processing and for fodder. For reception of seeds for food purposes there are restrictions on pollution of soil: 1125 kBk/square ? (30 Ci/square km) and 90Sr to 2,6 kBk/square ? (0,07 Ci/square km)

    125I-soya-saponin was prepared to study the distribution of soya-saponin in body of rat, as well as in different areas of brain when peritoneal injection. The results showed that the peak value of radioactive soya-saponin in all tissue appeared at 30 min after peritoneal injection. There were higher radioactivities in brain and suprarene comparing with other organs. The highest radioactivity was seen in hypothalamus among the every brain areas. It is a first report that soyasaponin can pass through the blood brain barrier when peripheral injection. The result also supported the opinion that soyasaponin might act on the hypothalamus and central regulation of cardiovascular system. Another finding was that soyasaponin also showed a higher affinity with adrenal gland, which indicated that the soyasaponin might possess of peripheral effect for regulation of cardiovascular system as well

    2012-08-01

    The natural occurrence of alternariol (AOH) and alternariol monomethyl ether (AME) in soya beans harvested in Argentina was evaluated. Both toxins were simultaneously detected by using HPLC analysis coupled with a solid phase extraction column clean-up. Characteristics of this in-house method such as accuracy, precision and detection and quantification limits were defined by means of recovery test with spiked soya bean samples. Out of 50 soya bean samples, 60% showed contamination with the mycotoxins analyzed; among them, 16% were only contaminated with AOH and 14% just with AME. Fifteen of the positive samples showed co-occurrence of both mycotoxins analyzed. AOH was detected in concentrations ranging from 25 to 211 ng/g, whereas AME was found in concentrations ranging from 62 to 1,153 ng/g. Although a limited number of samples were evaluated, this is the first report on the natural occurrence of Alternaria toxins in soya beans and is relevant from the point of view of animal public health.

    1987-01-01

    Raw soya flour (RSF) is thought to cause pancreatic hypertrophy in rats because trypsin inhibitor in the flour binds trypsin in the gut lumen and this lowering of free trypsin concentrations leads to the release of cholecystokinin (CCK). Intestinal enzyme concentrations were therefore studied in rats fed RSF for from one hour to 400 days to determine whether free trypsin concentrations were depressed during the period of pancreatic growth (up to six to eight weeks after starting RSF).

  7. Effects of heat processing on soya bean fatty acids content and the lipoxygenase activity

    Directory of Open Access Journals (Sweden)

    Žilić Slađana M.

    2010-01-01

    Full Text Available Effects of increased temperatures on the lipoxygenase activity and changes of soya bean fatty acids were observed in the present study. The kernels of soya bean cultivars Bosa and ZPS 015 were subjected to the treatments of extrusion, autoclaving, micronisation and microwave roasting. Depending on the technological processing procedure, the kernels were exposed to temperatures ranging from 60 to 150°C for 25 to 30 seconds during extrusion and for 30 minutes during autoclaving. The temperature that developed in the course of the microwave radiation and autoclaving did not cause statistically significant differences between oil content in heat treated and fresh kernels of soya bean. However, the oil content was higher in soya bean flakes (micronized kernels and lower in grits than in fresh kernels. The heat treatments resulted in the significant decrease of the linolenic fatty acid content. Depending on the temperature and applied heat treatments, the content of linoleic and oleic fatty acid oscillated. High temperatures caused changes in unsaturated fatty acids with 18 carbon atoms resulting in relative increase of the stearic acid content. The lipoxygenase activity decreased in correlation with increased temperatures and the time of heating. The maximum drop of the activity was observed after kernel exposure to the extrusion and micronisation processes at the temperature of 100oC. However, a significant lipoxygenase activity increase was recorded in both studied cultivars after one-minute microwave heating, i.e. at the temperature about 60°C. A further temperature increase led to a gradual denaturation of the enzyme and therefore to its decreased activity.

    2014-08-01

    To evaluate the safety of biogenic amines, high performance liquid chromatography (HPLC) was used to evaluate the levels of biogenic amines in fermented soya beans and fermented bean curd. In fermented soya beans, the total biogenic amines content was in a relatively safe range in many samples, although the concentration of histamine, tyramine, and β-phenethylamine was high enough in some samples to cause a possible safety threat, and 8 of the 30 samples were deemed unsafe. In fermented bean curd, the total biogenic amines content was more than 900 mg/kg in 19 white sufu amples, a level that has been determined to pose a safety hazard; putrescine was the only one detected in all samples and also had the highest concentration, which made samples a safety hazard; the content of tryptamine, β-phenethylamine, tyramine, and histamine had reached the level of threat to human health in some white and green sufu samples, and that may imply another potential safety risk; and 25 of the 33 samples were unsafe. In conclusion, the content of biogenic amines in all fermented soya bean products should be studied and appropriate limits determined to ensure the safety of eating these foods. PMID:25029555

    Detection and imaging of the herbicide mesotrione (2-(4-mesyl-2-nitrobenzoyl)cyclohexane-1,3-dione) and the fungicide azoxystrobin (methyl (E)-2-{2-[6-(2-cyanophenoxy)pyrimidin-4-yloxy]phenyl}-3-methoxyacrylate), on the surface of the soya leaf, and the detection and imaging of azoxystrobin inside the stem of the soya plant, have been achieved using matrix-assisted laser desorption/ionisation quadrupole time-of-flight mass spectrometry. In leaf analysis experiments, the two pesticides were deposited onto the surface of individual soya leaves on growing plants. The soya leaves were removed and prepared for direct and indirect (following blotting onto matrix-coated cellulose membranes) imaging analysis at different periods after initial pesticide application. In stem analysis experiments, azoxystrobin was added to the nutrient solution of a soya plant growing in a hydroponics system. The plant was left for 48 h, and then horizontal and vertical stem sections were prepared for direct imaging analysis. The images obtained demonstrate the applicability of MALDI imaging to the detection and imaging of small organic compounds in plant tissue and further extend the analytical repertoire of the versatile MALDI technique.

    Whole oilseeds such as soya beans have been utilized in dairy rations to supply additional fat and protein. However, antinutritional components contained in soya beans, such as trypsin inhibitors and haemagglutinins (lectins) may alter digestibility of nutrients and consequently affect animal performance. The objective of the present experiment was to quantify the effect of different levels of whole raw soya beans in diets of dairy cows on nutrient intake, total tract digestion, nutrient balances and milk yield and composition. Sixteen mid to late-lactation cows (228 ± 20 days in milk; mean ± SD) were used in four replicated 4 × 4 Latin square design experiment with 21-d periods. Cows were assigned to each square according to milk yield and DIM. The animals were randomly allocated to treatments: control (without soya beans addition; CO), WS9, WS18 and WS27, with addition of 9%, 18% and 27% of whole raw soya bean in diet on a dry matter (DM) basis respectively. All diets contained identical forage and concentrate components and consisted of maize silage and concentrate based on ground corn and soya beans at a ratio of 60:40. There were no differences in OM, CP, NDF and NEL intakes (kg/day and MJ/day) among the treatments (p > 0.05). However, DM and NFC intakes were negatively affected (p = 0.04 and p < 0.01, respectively) and ether extract (EE) intake was positively affected (p < 0.01). Total tract digestion increased linearly with whole raw soya beans for EE (p < 0.01) and NDF (p = 0.01). The excretion (kg/day) of digested soya beans grains increased linearly according to addition of whole raw soya beans. However, the nutritive characteristics of excreted grains were not altered. Milk (kg), milk lactose (kg) and protein (kg) yield decreased linearly (p < 0.01, p < 0.01 and p = 0.04, respectively) milk fat content (%) increased linearly (p < 0.01) with whole raw soya beans inclusion. Increasing addition of whole raw soya beans affected milk fatty acid profile

  2. Effect of gamma irradiation on methionine and tryptophan content in soya protein products

    International Nuclear Information System (INIS)

    Effect of gamma irradiation on the content of methionine and tryptophan in soya protein products were investigated. Irradiation with doses of 1, 3 and 5 kGy caused significant (p = 0.05) decrease of methionine contents. Parallel with the decrease in methionine also the relative quality of proteins is lowered. Tryptophan content were significantly reduced (p = 0.05) at irradiation doses of 3 and 5 kGy. The relative decrease of methionine and tryptophan contents are significantly correlated (p = 0.05) with relative increase in amount of products by the irradiation induced oxidation of lipids; correlation coefficients were 0.576 and 0.715

    Full Text Available This study concentrated on the effects of preservatives on shelf life of yoghurt produced from Soya beans milk. The yoghurt was produced by heating Soya beans milk slurry, cooled and incubated with starter culture. After the required yoghurt has been formed, sugar, flavour and preservatives were added. Study of the effect of preservatives revealed that Sodium benzoate preservative used at 20mg/ml give the best (optimum preservation on both shelf and refrigeration storage for 15 and 21 days respectively. This is because the inhibitive ability of Sodium benzoate at lower temperature is higher than that of Potassium metabisulphate preservative. The study also revealed that 40mg/ml concentration of the combined preservatives gives the best (optimum concentration level for both shelf and refrigeration storage with pH values of 3.92 and 4.01 respectively after 14 days fermentation. The preservatives concentration added are within the threshold values specified by Standard Organization of Nigeria (SON and National Agency for Food Administration and Control (NAFDAC.

    2016-04-01

    Full Text Available Biodiesel is biodegradable, clean-burning, non-toxic, renewable, high-quality, and cheap diesel fuel made primarily from waste vegetable oil which can be used without any alterations in engine design. The paper is concerned with the extraction and quality evaluation of the biodiesel fuels synthesized from waste soya bean cooking oil. Waste soya bean cooking oil had high amount of free fatty acid. Thus, single step transesterification process with the aid of homogeneous catalyst as 1% potassium hydroxide were implemented in this experiment. Methanol was chosen as alcohol solvent. In the transesterification process, the triglycerides in waste cooking oil was reacted with a methanol to form esters and glycerol as by product.The biodiesel were extracted for different oil to methanol ratio as 1:2, 1:3 and 1:4. The highest biodiesel yield of 76% was obtained at 1:3 volumetric ratio for 60 ºC reaction temperature and 1250 rpm stirring speed. Results show that the optimal methyl ester yield of 90% occurred at methanol: oil volume ratio of 3:1. The product met the ASTM fuel standards for relative density, acid value, relative density, calorific value, flash point and kinematic viscosity.

  11. Degradation of 14C-Lindane(gamma-hexachlorocyclohexane) in Corn and Soya Bean Seedlings

    International Nuclear Information System (INIS)

    The degradation of lindane (gamma-hexachlorocyclohexane,(gamma-HCH) by corn and soya bean seedlings has been studied. Following root application, anumber of metabolic products were identified utilizing Gas-liquid chromatography and GLC-mass spectrometry. In corn seedlings, these metabolites proved to be m-dichlorobenzene;1,2,4-trichlorobenzene; 1,2,4,5-tetrachlorobenzene; 2,4,5-and 2,3,5-trichlorophenols and gamma-pentachlorocyclohex-1-ene as compared with the standards. In soya bean seedlings, however, while 1,2,3,4-tetrachlorobenzene and 2,3,5-trichlorophenol were missing, 1,2,3-trichlorobenzene and 2,4,6-trichlorophenol were produced. Of the total chlorinated compounds found in hexane extracts, these metabolic products accounted for 30-35%. The amount of trichlorophenols which contributed to 38% and 16% of the metabolic output in corn and peas respectively, provided futher evidence that the degrading pathways in monocots might differ from these in dicots. The results also show that in both plant tissues dechlorination generally took place and represented adominant intermediary detoxification process

  12. Radioprotective effects of soya and garlic oils in irradiated male rats

    International Nuclear Information System (INIS)

    Forty male albino rats were divided equally into four groups, the first group acted as control group, the second group was subjected to 5 Gy whole body gamma irradiation, the third group was injected intraperitoneally daily with soya oil (15 mg/kg b.w. for 14 days) before gamma irradiation and the fourth group was injected intraperitoneally daily with garlic oil (150/kg b.w. for 14 days) before gamma irradiation. Mortality percentage and body weight were recorded. Blood samples were collected one week post-gamma irradiation from all animals for biochemical analysis. Serum levels of thiobarbituric acid reactive substance (TBARS), total lipids, triglycerides and cholesterol were measured. Total proteins and albumin were measured using photometric methods. Globulin value was calculated by subtraction of albumin from total protein values. The results showed that gamma irradiation with dose level of 5 Gy induced retardation of live body weight and increased the mortality. The data also showed significant increases in TBARS, total lipids, triglycerides and cholesterol levels, whereas the levels of total proteins, albumin and globulin were significantly decreased. The soya oil or garlic oil injected pre-irradiation exerted noticeable amelioration in induced radiation changes on body weight, mortality, TBARS, lipid profiles and protein fractions

    2011-01-01

    Full Text Available Chocolate is a complex rheological system in which non-fat cocoa particles and sugar particles are enveloped by crystal matrix of cocoa butter. Physical properties of chocolate depend on ingredient composition, method of production and properly performed pre-crystallization phase. In this work, chocolate was produced in an unconventional way, i.e. in a ball mill applying variable refining time (30, 60 and 90 min and pre-crystallization temperature in chocolate masses (26, 28 and 30⁰C. Two types of chocolate were produced: chocolate with 20% of powdered cow’s milk (R1 and chocolate with 20% of soya milk powder (R2. The quality of chocolate was followed by comparing nutritive composition, 23 polyphenol content, hardness of chocolate, solid triglyceride content (SFC and rheological parameters (Casson yield flow (Pa, Casson viscosity (Pas, the area of the thixotropic loop, elastic modulus and creep curves. The aim of this paper is determining changes caused by replacing cow’s milk with soya milk powder in respect of nutritive, rheological and sensory properties, as well as defining optimal parameters: precrystallization temperature and refining time of soya milk chocolate in order to obtain suitable sensory and physical properties identical to those of milk chocolate mass. The results show that replacing powdered cow’s milk with soya milk powder affects the increase in nutritive value of soya milk chocolate. R2 chocolate mass showed the increase in essential amino acids and fatty acids. This chocolate mass also showed the increase in total polyphenols by 28.1% comparing to R1 chocolate mass. By comparing viscosity, yield stress, shear stress and the area of the thixotropic loop, it can be observed that R1 chocolate mass represents a more organized and simpler system than the mass with soya milk (R2, as it shows lower values for all the above mentioned parameters, regardless of the refining time and pre-crystallization temperature

    Full Text Available In this paper we discuss the Value–at–Risk concept and we analyse the market risk by using EWMA approach. EWMA (exponentially weighted moving average forecasting technique is a popular measure of various risks in financial risk management. We will compare standard EWMA, robust EWMA and skewed EWMA forecast of VaR. JP Morgan standard EWMA is derived from Gaussian distribution. Robust EWMA is based on Laplace distribution and skewed EWMA is a new approach derived from an asymmetric Laplace distribution. Asymmetric Laplace distribution takes into account both skewness and heavy tails in return distribution and the time varying nature of them in practice. Skewed EWMA VaR is a generalization of the standard EWMA method. Using these approaches we will analyse selected financial series (three European market indexes and one exchange rate. We have found andconfirmed that skewed EWMA forecasting of VaR outperforms the standard EWMA method.

    Full Text Available In accordance with Article 6 of Regulation (EC No 396/2005, the United Kingdom, hereafter referred to as the evaluating Member State (EMS, received an import tolerance application from Exponent International Ltd., on behalf of BASF Corporation, to set MRLs for the use of the active substance imazapyr in genetically modified soya bean grown in Brazil, imidazolinone-tolerant lentils, rape and mustard plants grown in Canada and sunflowers in Argentina. The United Kingdom proposed to set MRLs of 5 mg/kg in soya bean, 0.08 mg/kg in sunflower seed, 0.05 mg/kg in rape seed and mustard seed and 0.2 mg/kg in lentils. The United Kingdom drafted an evaluation report in accordance with Article 8 of Regulation (EC No 396/2005 which was submitted to the European Commission and forwarded to EFSA. According to EFSA the data are sufficient to derive MRL proposals of 5 mg/kg on soya bean, 0.08 mg/kg on sunflower seed, the limit of quantification (LOQ of 0.05 mg/kg on rape and mustard seed and 0.3 mg/kg on lentils. In the countries of origin the MRLs are set at 3 mg/kg on soya bean, 0.05 mg/kg on sunflower, rape and mustard seed and 0.2 mg/kg on lentils. Adequate analytical enforcement methods are available to control the residues of imazapyr in the crops under consideration. Based on the risk assessment results, EFSA concludes that the proposed uses of imazapyr in soya bean, sunflower seed, rape seed, mustard seed and lentils will not result in a consumer exposure exceeding the toxicological reference value and therefore are unlikely to pose a consumer health risk.

  4. Neutron activation analysis of Standard Materials of Comparison IAEA- the corn and soya flour

    International Nuclear Information System (INIS)

    It is known that maintenance of quality of results of neutron activation analysis (NAA), no less than in other analytical methods, is one of key problems. Thus first of all it is necessary to provide correctness of results. The most correct way of revealing and elimination of regular errors is carrying out of analyses of Standard Samples of Comparison (SSC) by the developed techniques and comparison of the received results with the certificated results. Therefore, the analysis and certification of various SSC is one of the most actual tasks of modern analytical chemistry. One of few organizations engaged in manufacture SSC for NAA, is IAEA which has organized the Project on certification of samples of comparison - a corn and soya flour. Among many laboratories worldwide, in this Project the Laboratory of the Activation Analysis of Pure Materials of Institute of Nuclear Physics Academy of Sciences Republic of Uzbekistan also participated. We carry out series of analyses of samples of corn and soya flour, candidates for standard samples of comparison, by the method of instrumental NAA. The preparing of samples was carried out by the technique described in the technical project applied to these materials. Samples before the analysis dried up at temperature 80 degree C during 24 h. Cooled, weighed and irradiated in the vertical channel of a nuclear reactor of VVR-SM of Institute of Nuclear Physics Academy of Sciences Republic of Uzbekistan during 0,5-1 h (depending on determined elements) with density of a stream of neutrons 1 x 1014 neutrons/cm2 sec. Time of cooling from 10 min up to 10 days. Time of measurement from 100 sec up to 3000 sec. Measurements were carried out on gamma spectrometer consisting of HPGe detector GC1518 and digital multichannel analyzer DSA-1000('Canberra', USA). Processing of the spectrometer information carried out with the help of software package Genie-2000. As a result of the carried out analyses we determine contents of 21 elements in corn

    Full Text Available Sorption isotherm of soya bean (Glycine max (L. Merr. was obtained by the dynamic experimental method. Artificial Neural Networks (ANNs were used for modeling soya bean equilibrium moisture content (EMC. Thermodynamic equations and trained ANN for prediction of two thermodynamic properties of net isosteric heat and entropy of soya bean were utilized. The ANN models were better compared with mathematical models. In this study, the isosteric heat and entropy of sorption of soya bean were separately predicted by two power models as a EMC function. Predictive power of the models was high (R² ≈ 0.99. At the moisture content above 11% (dry basis, db, isosteric heat and entropy of sorption of soya bean were smoothly decreased, while they were highest at moisture content about 8% (db. Isosteric heat and entropy would be useful in the storage simulation of dried soya bean. The ANN model predicts soya bean EMC more accurately than mathematical models. Hence, better equations could be developed for the prediction of heat of sorption and entropy based on data from the ANN model.La isoterma de desorción de soya (Glycine max (L.

    2004-01-01

    The VaR, a new appearing financial risk-manage tool, have been applied widely. Many financial setups have accustomed to measure the risk of a portfolio with the VaR. So it is very necessary to discuss the portfolio choice problem under the VaR constraint. In this paper, by setting and solving the portfolio choice model under the VaR constraint, we illustrate that the use of the VaR constraint reduces the array of choice to a more manageable range. The probability of traget VaR, therefore, can be thought of as a risk tolerance assessment tool (when coupled with another measure of risk).

    Soya bean (Glycine max) and grass pea (Lathyrus sativus) seeds are important sources of dietary proteins; however, they also contain antinutritional metabolite oxalic acid (OA). Excess dietary intake of OA leads to nephrolithiasis due to the formation of calcium oxalate crystals in kidneys. Besides, OA is also a known precursor of β-N-oxalyl-L-α,β-diaminopropionic acid (β-ODAP), a neurotoxin found in grass pea. Here, we report the reduction in OA level in soya bean (up to 73%) and grass pea (up to 75%) seeds by constitutive and/or seed-specific expression of an oxalate-degrading enzyme, oxalate decarboxylase (FvOXDC) of Flammulina velutipes. In addition, β-ODAP level of grass pea seeds was also reduced up to 73%. Reduced OA content was interrelated with the associated increase in seeds micronutrients such as calcium, iron and zinc. Moreover, constitutive expression of FvOXDC led to improved tolerance to the fungal pathogen Sclerotinia sclerotiorum that requires OA during host colonization. Importantly, FvOXDC-expressing soya bean and grass pea plants were similar to the wild type with respect to the morphology and photosynthetic rates, and seed protein pool remained unaltered as revealed by the comparative proteomic analysis. Taken together, these results demonstrated improved seed quality and tolerance to the fungal pathogen in two important legume crops, by the expression of an oxalate-degrading enzyme. PMID:26798990

    Highly concentrated oil-in-water (o/w) emulsion stabilised by means of gluten and soya protein isolate (SPI) at low pH have been characterized by means of linear dynamic viscoelasticity and droplet size distribution analysis (DSD). The microstructure of these emulsions has been characterized at a colloidal level by using confocal laser scanning microscopy (CLSM) and light microscopy (LM). These emulsions always exhibited a behaviour characteristic of highly flocculated emulsions with a mechanical spectrum showing a well-developed plateau region. DSD results generally showed log normal bimodal profiles. Microstructure images revealed occurrence of a close packing of droplets with a broad distribution of sizes participating in the formation of a three dimensional flocculated network. The Mason model of elasticity of compressed emulsions has been used to correlate viscoelastic and microstructural parameters giving adequate fitting but underestimating the elastic properties obtained for the highest concentration of gluten. These deviations may be explained in terms of an enhancement of the elastic network formed in the aqueous phase in which the glutenin fraction must play an important role. (orig.)

  4. Natural Radionuclides Intake into Soya, Corn and Lettuce Grown on Soil Amended with Phosphogypsum

    International Nuclear Information System (INIS)

    Phosphogypsum is a by-product of the phosphate fertilizers industry and is produced by precipitation during wet process of phosphate rocks, thus posing serious problems with its utilization and safe disposal. In Brazil, three main industries are responsible for the production and storage of about 5.5x106 tons per year. PG may contain radionuclides of U and Th series. The main objective of this study is to evaluate the environmental impact of the use of phosphogypsum as soil amendment by evaluating the radionuclides transfer in the soil/plant system. To accomplish this task an experiment was carried out in green house, where two major crop groups ( soya and corn ) and leafy vegetable (lettuce) were grown in two types of soil ( clay and sandy ) amended with phosphogypsum. The radionuclides 226Ra, 228Ra and 210Pb were determined by a radiochemical procedure and by gamma spectrometry. 210Po was spontaneously plated on a silver disc and measured by alpha spectrometry. Activity concentrations of 238U and 232Th in soil, phosphogypsum, crops and lettuce were determined by using instrumental neutron activation analysis (INAA). The transfer-factors were evaluated for all the radionuclides analyzed. (author)

    Pseudomonas is one of the most common genera in black Perigord truffle. Its inactivation by high pressure (100-500 MPa/10 min) applied on truffles at sub-zero or low temperatures was studied and compared with those of Pseudomonas fluorescens in tryptone soya broth. Pressurization of truffles at 300 MPa/4 °C reduced the bacterial count of Pseudomonas by 5.3 log cycles. Higher pressures of 400 or 500 MPa, at 4 °C or 20 °C, allowed us to slightly increase the level of destruction to the value of ca. 6.5 log cycles but did not permit us to completely inactivate Pseudomonas. The results showed a residual charge of about 10 CFU/g. Pressure-shift freezing of truffles, which consists in applying a pressure of 200 MPa/-18 °C for 10 min and then quickly releasing this pressure to induce freezing, reduced the population of Pseudomonas by 3.3 log cycles. The level of inactivation was higher than those obtained with conventional freezing. Endogenous Pseudomonas in truffle was shown to be more resistant to high pressure treatments than P. fluorescens used for inoculation of broths.

    This study was planed to determine the role of single oral dose of avocados and soya in irradiated rats exposed to gamma radiation. the experimental animals were randomly divided into four groups; 12 rats for each. Group 1: kept as control. Group 2: rats received piascledine for 14 consecutive days. Group 3: rats submitted to whole body gamma rays (4 Gy). Group 4: rats received the same piascledine 14 days post-exposure to 4 Gy gamma radiation. The animals were weighed then dissected after one and fourteen days post-administration and the cardiac tissue and plasma were stored at 12oC till used for biochemical analysis and kept in ice. The following parameters were determined: plasma total cholesterol, triacylglycerol, high density lipoprotein-cholesterol, low density lipoprotein-cholesterol, LDH, phospholipids, ALT, CPK and TBARS. In cardiac tissue, determinations of total cholesterol, triacylglycerol, phospholipids and TBARS were conducted.It can be concluded that administration of avocados and soy as natural drug (piascledine) post-irradiation in rats is a favorable modificator against the impaired physiological processes in animal body due to gamma irradiation

    2010-07-01

    Full Text Available In the recent past, the crude oil prices have increased immensely as the fossil fuels are depleting, biodiesel has emerged as an alternative fuel for the petroleum. In this context the use of bio-diesel in the gas turbine seems a solution for power generation problems and their environmental concerns. Vegetable oils, due to their agricultural origin, are able to reduce net carbon dioxide emissions to the atmosphere. However, there are several operational and durability problems which may arise in using straight vegetable oils, which are because of their higher viscosity and low volatility compared to mineral diesel fuel. Bio-fuels, an alternative fuels are having environmental benefit as; they are made from renewable sources. It can be blended in any proportion with mineral Diesel. Many performance and emission tests are being carried out in reciprocating diesel engines that use bio fuel but there are very few tests has been done on gas turbine engines. The gas turbine combustion is steady flame combustion. This feature creates the wide range for the different alternative fuels for clean combustion in the gas turbine, such as natural gas, petroleum distillates, pyrolysis wood gas, biogas of methanisation, bio-diesel etc. The present work is an analysis of the Soya bio-diesel productionprocess i.e. trans-esterification, the different parameters affecting on trans-esterification. The different physical and chemical properties of this bio-diesel and diesel has been determined and compared to establish the suitability of the bio-diesel in the gas turbine. An analysis on High Performance Liquid Chromatography (HPLC has been done to find out the composition of the different fatty acid esters. The effect of these fatty acids onthe property of the bio-diesel has also been explained such as viscosity, heat of combustion, cetane No, cold flow properties, lubricity and oxidative stability etc. This will also help us to select best suited bio-diesel for the

    J. A. Freixas

    2010-01-01

    Full Text Available La soya (Glycine max L. Merr. establece simbiosis con bacterias fijadoras del nitrógeno de la familia de los rizobios; específicamente con bacterias del género Bradyrhizobium. Los rizobios secretan moléculas específicas denominadas factores Nod, que juegan un papel importante en el desarrollo del nódulo radicular. En el nódulo, los rizobios son diferenciados en bacteroides, donde ocurre la fijación biológica del nitrógeno (BNF y se produce amonio. La mayor parte del amonio es asimilado en glutamina, que participa indirectamente en la síntesis de ureidos. La soya se considera una de las plantas leguminosas más sensibles al estrés por sequía, con una disminución significativa en la BNF. Los ureidos se acumulan en plantas de soya sensibles a la sequía durante el déficit hídrico, mientras que las plantas tolerantes presentan bajas concentraciones de ureidos que pueden reducir el estrés sobre la BNF. Se han realizado investigaciones dirigidas a incrementar la BNF en condiciones de estrés por sequía. La fertilización con manganeso en condiciones moderadas de déficit hídrico incrementa la degradación de los ureidos y la BNF. La enzima ACC desaminasa en los rizobios degrada el ACC, precursor inmediato del etileno en las plantas, y disminuye los efectos inhibitorios del etileno en la nodulación. La inducción de los genes de la nodulación en Bradyrhizobium sp. ha mostrado efectos positivos en el crecimiento de la soya en condiciones moderadas de sequía. El objetivo de esta revisión bibliográfica está dirigido a relacionar nuevos blancos moleculares que permitan incrementar la BNF en condiciones de estrés por sequía.

    This paper deals with the study of the vegetable oils (VO) used as fuel for heating. The properties of sunflower, rape and soya oils are studied and these are compared with the properties of C-diesel fuel (used for heating domestic purposes in Spain). The mixtures of VO and diesel are studied and characterized and, finally, the results of a series of combustion trials of the mixtures in a conventional heating installation with a mechanical pulverization burner are presented. The results show that viscosity of VO limits the use of blends up to 40% of them, and the oxygen present in their structures contributes to an efficiency gain. (author)

  12. Polish reference material: soya bean flour (INCT-SBF-4) for inorganic trace analysis - preparation and certification

    International Nuclear Information System (INIS)

    Preparation, examination and certification of the new matrix reference material of biological origin: Soya Bean Flour (INCT-SBF-4) is described. The material was prepared from soya bean grown in India, not genetically modified. After milling, the material was sieved through the 150 mm nylon sieves and stored in a polyethylene (PE) bag. Approximately 50 kg of sieved soya bean flour was collected. Examination by optical microscopy revealed that Martin's diameter of over 90% of particles was below 50 mm. The whole lot of soya bean flour was then homogenized by mixing for 20 hours in a 110 dm3 PE drum rotated in three directions. Preliminary homogeneity testing by X-ray fluorescence (XRF) method and final checking of homogeneity by neutron activation analysis (NAA) after distribution of the material into containers revealed, that it is sufficiently homogeneous at least for a sample size ≥ 100 mg. In order to assure the long-term stability, all containers with INCT-SBF-4 were sterilized by electron beam radiation. Long-term stability was checked by analyzing concentrations of selected elements in the material stored in the air-conditioned room at 20 oC. Short-term stability was examined by the determination of concentrations of the selected elements in the bottle stored in the CO2 incubator at 37 oC. The material was certified on the basis of a worldwide interlaboratory comparison, in which 92 laboratories from 19 countries participated providing 1107 laboratory averages (4873 individual determinations) for 58 elements. A method of data evaluation leading to assignment of certified values was the same as that used previously in the Laboratory of the Department of Analytical Chemistry, Institute of Nuclear Chemistry and Technology. The results for a few elements were obtained by definitive methods developed in the Laboratory and used to support the certification process. Analytical uncertainties and stability uncertainties were quantified to arrive at combined

    Full Text Available Recently, modern techniques have been applied for analysis of the influence of polymers on microstructural properties of Portland cement, such as Thermogravimetric Analyses (TG, Scanning Electronic Microscopy (SEM, Fourier Transform Infrared Spectroscopy (FT-IR and Mercury Intrusion Porosimetry (MIP. In this study, thermogravimetric analyses were used to study the influence of vinyl acetate-versatic vinylester copolymer (VA/VeoVA in seven pastes of 28-day old Portland cement, in which distinct polymer contents and water/cement ratios were employed. In addition, analyses of FT-IR and MIP on Portland cement pastes modified by the copolymer were employed. The results showed that the addition of polymer interferes significantly in the reduction of Portlandite formation and increases the porosity of the matrices. A possible chemical interaction between the copolymer and hydrated products of Portland cement was also observed.

    Full Text Available Aim: Sugarcane press residue (SPR, a by-product of sugarcane industry, which is rich in inorganic salts was assessed at different levels in both soya based and fish based diets of layers for egg shell and yolk quality characteristics. Materials and Methods: SPR was incorporated in 32-week-old white leghorn layer diets at 0%, 5%, 10% and 15% either in the soya based or fish based diets to form T1 to T8 diets, respectively. Each diet was offered to five replicates of four laying hens each constituting a total of one sixty birds kept for 84 days under colony cages. Results: Mean egg shell thickness obtained from eggs of experimental hens measured was 0.342, 0.329, 0.320, 0.322, 0.319, 0.332, 0.328 and 0.336 mm in T1 through T8 groups, respectively. About the main factor effects, both showed non-significant results. Similarly, influence of different treatment diets, in imparting colour to the yolks, was found to be non-significant (p>0.05 at different 28-day time intervals. Further, the average yolk index values ranged non-significantly from 0.360 (T6 to 0.383 (T4. Conclusion: The SPR can be incorporated into layer diet as a source of inorganic as well as organic nutrients without affecting its egg quality characteristics.

    2014-01-01

    Full Text Available La soya es un cultivo que se asocia naturalmente con bacterias del género Bradyrhizobium , a través de una simbiosis en la que la planta garantiza fuente de nutrientes y energía al microorganismo y este le aporta nitrógeno que fija de la atmósfera. Además de múltiples señales moleculares que rigen la interacción entre la planta y el microorganismo, las condiciones del suelo influyen sobre el éxito o el fracaso en la nodulación. En este trabajo se estudió el efecto de diferentes inoculantes a base de Bradyrhizobium japonicum sobre la nodulación de la soya, variedad Pioneer 94M30, ante condiciones adversas como bajas temperaturas, acidez y exceso de agua. Se observó que el empleo de inoculantes inducidos influyó positivamente sobre los parámetros de nodulación evaluados en las condiciones de estrés impuestas, así como que el efecto de diferentes dosis del inoculante depende del tipo de estrés y de su intensidad. Estos resultados, aunque preliminares, mostraron un posible efecto antiestrés de los inoculantes inducidos ante tales condiciones ambientales.

    Full Text Available El presente estudio se desarrolló en las instalaciones del Instituto Nacional de Ciencias Agrícolas, con el objetivo de evaluar la radiosensibilidad de semillas de soya a los rayos gamma 60Co. Para su ejecución, se seleccionaron e irradiaron muestras de 50 semillas de la variedad Cubasoy-23, las que fueron sembradas en condiciones semicontroladas (macetas en la campaña de primavera, 1997. Las dosis de radiación fueron desde los 50 hasta los 480 Gy, con incrementos de 50 Gy entre las dosis de 50 y 200 Gy e incrementos de 40 Gy entre esta última y la dosis de 480 Gy. Las evaluaciones realizadas consistieron en porcentaje de semillas germinadas a los tres, seis y nueve días de la siembra, altura de las plantas a los 10, 20 y 50 días y número de pares de hojas emitidas a los 10 y 20 días de la siembra. El estudio realizado evidenció la ocurrencia de un efecto fuerte de las dosis aplicadas en el porcentaje de semillas germinadas, resultando las dosis próximas a los 280 Gy las de mayor efecto radioestimulador de la germinación. Desde el punto de vista de la altura de las plantas, el efecto de las dosis aplicadas se correspondió con el descrito para otros materiales biológicos irradiados, caracterizándose este por un aumento a dosis bajas seguido por una reducción cada vez mayor a medida que las dosis aplicadas se incrementaron. Por su parte, la emisión de hojas por las plantas mantuvo un comportamiento en correspondencia con la altura de las plantas. Los resultados del estudio permiten sugerir la aplicación de dosis próximas a los 360 Gy en los trabajos dirigidos a la creación de variabilidad genética en programas de mejora por inducción de mutaciones

One year after a Veterans Affairs (VA scandal was ignited here in Phoenix, the number of veterans on wait lists is 50 percent higher than at the same time last year, according to VA data (1. The VA is also facing a nearly $3 billion budget shortfall. VA Secretary Bob McDonald has asked for “flexibility” to reallocate billions of dollars in clinical funds to cover the shortfall. Since the scandal broke last year, VA providers have increased their workloads, adding 2.7 million more appointments than the previous year. However, the VA has played "games" with patient eligibility for years. When money was plentiful VA administrators would open the doors to patients since the following years' budgets were based on the number of patients seen. However, when money was tight, the doors would be slammed shut leaving many patients in the lurch scrambling to obtain health care elsewhere. Now it appears ...

    Full Text Available A field study was undertaken on the residual effect of organic fertilisers applied to the preceding rice cropping on nitrogen fixation of soya in a rice-soya cropping system. The experiment was conducted on a farmer’s lowland paddy in Mae Rim district, Chiang Mai province, Thailand. Organic fertiliser treatments assigned were: 1 control (no fertiliser, 2 animal manure of cattle (AM, 3 compost (CP, 4 azolla (AZ, 5 AM + CP, 6 AM + AZ, 7 CP + AZ and 8 AM + CP + AZ. Soya seeds were planted without rhizobial inoculation in December 2011, four months after the application of organic fertilisers. Nodule weight, total shoot nitrogen accumulation and relative ureide index at various growth stages were recorded as the indices of nitrogen fixation. Results of the study demonstrate that the residues from the application the organic fertilisers of narrow C/N ratios during the land preparation for rice cropping four months before soya cultivation promoted nitrogen fixation by native rhizobia.

    An experiment was conducted to study disappearance of C14 to C18 fatty acids, lag times and biohydrogenation (BH) rates of C18 fatty acids of ground soya bean and canola seeds in situ. Three ruminally fistulated Dallagh sheep were used to determine ruminal BH of unsaturated fatty acids (UFAs). Differences in the disappearance of fatty acids through the bags and lag times were observed between the oilseeds. We saw that the longer the incubation time of the oilseeds in the rumen, the lower the content of C18:2 and C18:3. Significantly higher lag times for both C18:2 and C18:3 were observed in ground canola compared to ground soya bean. BH rates of C18:2 and C18:3 fatty acids in soya bean were three times higher than those of canola. These results suggest that the fatty acid profile of fat source can affect the BH of UFAs by rumen micro-organisms. So that UFAs of canola had higher ability to escape from ruminal BH. It seems that fatty acid profile of ruminant products is more affected by canola seed compared to soya bean seed. PMID:26094995

  11. 1000-kVA arc power supply

    International Nuclear Information System (INIS)

    Because of ever-increasing power demands for the development of the Oak Ridge duoPIGatron ion source, a continuous-duty arc power supply was constructed for the Medium Energy Test Facility (METF) to furnish power for the plasma generator of experimental ion sources. The power supply utilizes 12-pulse rectification with half-wave switching in a delta and wye full-wave bridge that may be connected in series or parallel. It will deliver 340 V dc, 2500 A to an ion source when series connected and 170 V dc, 5000 A when paralleled connected. Silicon-controlled rectifiers (SCR) in each rectifier bridge can be switched for pulses as short as 10 ms through continuous duty. The filter section that reduces the ripple in the output consists of an inductor-to-capacitor (L-C) filter to smooth the 720-Hz pulses. The power transformer serves as an isolation transformer allowing the secondary to be elevated to the accelerating potential of the ion source. The dc output level is controlled with a 1000-kVA auto transformer connected to the primary of the power transformer. All elevated voltages and currents are monitored at ground potential with an optical telemetry system. This paper describes the power supply in detail, including block diagrams, component specifications, and waveforms when supplying power to an ion source

    KaVA (KVN and VERA Array) is a new combined VLBI array with KVN (Korean VLBI Network) and VERA (VLBI Exploration of Radio Astrometry). First, we briefly review the imaging capabilities of KaVA array which actually achieves more than three times better dynamic range than that achieved by VERA alone. The KaVA images clearly show detailed structures of extended radio jets in AGNs. Next, we represent the key science program to be led by KaVA AGN sub working group. We will conduct the monitoring observations of Sgr A* and M87 because of the largeness of their central super-massive black hole angular sizes. The main science goals of the program are (i) testing magnetically-driven-jet paradigm by mapping velocity fields of the M87 jet, and (ii) obtaining tight constraints on physical properties of radio emitting region in Sgr A*.

    Full Text Available Background: Genetically modified soya bean (GMSB is a commercialized food. It has been shown to have adverse effects on fertility in animal trials. Extra virgin olive oil (EVOO has many beneficial effects including anti-oxidant properties. The aim of this study is to elucidate if addition of EVOO ameliorates the adverse effects on reproductive organs of rats fed on GMSB containing diet. Methods: Forty adult male albino rats (150–180 g of Sprague Dawley strain were separated into four groups of 10 rats each: Group 1 – control group fed on basal ration, Group 2 – fed on basal ration mixed with EVOO (30%, Group 3 – fed on basal ration mixed with GMSB (15%, and Group 4 – fed on basal ration mixed with GMSB (15% and EVOO (30%. This feeding regimen was administered for 65 days. Blood samples were collected to analyze serum zinc, vitamin E, and testosterone levels. Histopathological and weight changes in sex organs were evaluated. Results: GMSB diet reduced weight of testis (0.66±0.06 vs. 1.7±0.06, p<0.001, epididymis (0.489±0.03 vs. 0.7±0.03, p<0.001, prostate (0.04±0.009 vs. 0.68±0.04, p<0.001, and seminal vesicles (0.057±0.01 vs. 0.8±0.04, p<0.001. GMSB diet adversely affected sperm count (406±7.1 vs. 610±7.8, p<0.001, motility (p<0.001, and abnormality (p<0.001. GMSB diet also reduced serum zinc (p<0.05, vitamin E (p<0.05, and testosterone (p<0.05 concentrations. EVOO diet had no detrimental effect. Addition of EVOO to GMSB diet increased the serum zinc (p<0.05, vitamin E (p<0.05, and testosterone (p<0.05 levels and also restored the weights of testis (1.35±0.16 vs. 0.66±0.06, p<0.01, epididymis (0.614±0.13 vs. 0.489±0.03, p<0.001, prostate (0.291±0.09 vs. 0.04±0.009, p<0.001, seminal vesicle (0.516±0.18 vs. 0.057±0.01, p<0.001 along with sperm count (516±3.1 vs. 406±7.1, p<0.01, motility (p<0.01, and abnormality (p<0.05.

  2. Soil erosion and mitigation measures on rented and owned fields in Uruguay: the impact of transgenic soya and foreign investors

    Science.gov (United States)

    2014-05-01

    Governments, companies and individuals with financial capital to invest, are worldwide buying or renting land in developing or third world countries. Uruguay is a developing country whose economy is mainly based on agriculture. Since 2000 many foreigners started to invest in the Uruguayan agricultural sector and to practice intensive large-scale agriculture. The significant presence of foreigners in the country is proven by the fact that almost 360 000 ha out of the 500 000 ha forming the study area were managed by foreigners in 2012. Nowadays farmers have abandoned the traditional crop rotation plan that included pasture to produce grain for export, and transgenic soya (soya RR) became the main crop planted by both foreigners and locals. Besides the high soil erosion rates related to having soya as main crop, planting soya implies the use of glyphosate, a broad-spectrum systemic herbicide leading to important environmental impacts. It is commonly said that foreigners investing in poor countries are exploiting the local natural resources aiming to get the highest possible profit from them. Is this a valid assumption in Uruguay? The purpose of this study was to compare the land management style of foreign and local farmers and to relate it to the soil erosion occurring in the study area. The land tenure (rented or owned fields) and the type of farmer interviewed ("individual farmer" equivalent to L.L.C. or "anonymous society" equivalent to P.L.C.) were taken into consideration during the analysis. Based on what stated by the farmers interviewed, the soil erosion simulations considered the seven most popular crop rotation plans on rented and owned fields, three ideals crop rotation plans, the application of no mitigation measures, and the construction of terraces and conservation buffers. Depending on the crop rotation plan, soils characterized by slope gradients higher than 2 resulted in soil erosion rates higher than the 7 ton/ha/year allowed by law. The highest

    Full Text Available Purpose: Experimental studies in alloxan-induced diabetic animals have demonstrated several abnormalities upon induction such as physiological, biochemical and histological alterations. In this present study, the influences of graded doses of soya bean oil supplementation for 4weeks on some biochemical parameters in alloxan-induced diabetes in rats were determined. Methodology: Sixty (60 male albino rats weighing about 240-260g were divided into 6 experimental groups of 10 rats per group viz: I, II, III, IV, V and VI. Group I serve as male control, group II serve as diabetes control which were fed with normal rat chow while rats in the test group were fed with graded doses of soya bean oil supplements and water ad libitum for 4weeks, at the end of the supplementation, plasma lipid profile and glucose level were determined. Results: All the diabetic induced rats had significantly higher (p<0.01 Glucose, Total cholesterol, Triglyceride, LDL-C, VLDL-C, but lower HDL-C levels than all the non-diabetic rats. The data obtained after supplementation revealed that soya bean oil significantly reduced the glucose level and ameliorated the lipid profile with attendant decrease in glucose, total cholesterol, triglyceride, LDL-C, VLDL-C levels, but with a corresponding increases in HDL-C levels respectively when compared to alloxan-induced diabetic rats. Conclusion: The observation of significant changes in plasma lipid profile, glucose level might be as a result of supplementation with soybean oil. It is therefore concluded that Soya bean oil possess significant antidiabetic activity that can improve the physiological and biochemical parameters which are abnormally altered due to diabetes mellitus.

  14. The cost of hospital readmissions: evidence from the VA.

    2016-09-01

    This paper is an examination of hospital 30-day readmission costs using data from 119 acute care hospitals operated by the U.S. Veterans Administration (VA) in fiscal year 2011. We applied a two-part model that linked readmission probability to readmission cost to obtain patient level estimates of expected readmission cost for VA patients overall, and for patients discharged for three prevalent conditions with relatively high readmission rates. Our focus was on the variable component of direct patient cost. Overall, managers could expect to save $2140 for the average 30-day readmission avoided. For heart attack, heart failure, and pneumonia patients, expected readmission cost estimates were $3432, $2488 and $2278. Patient risk of illness was the dominant driver of readmission cost in all cases. The VA experience has implications for private sector hospitals that treat a high proportion of chronically ill and/or low income patients, or that are contemplating adopting bundled payment mechanisms.

    The objective of this experiment was to replace soya bean oil with glycerol in laying hen diets and assess the change's effect on performance, parameters of egg quality and the egg fatty acid profile. A total of 60 44-week-old Hy-Line W36 laying hens were distributed according to a completely randomised experimental design into four treatments consisting of glycerol substitutions for soya bean oil dietary at varying inclusion levels (0%, 25%, 50% and 75%), with five replicates of three birds each. Dietary treatments had no significant effect on BW change, egg production, feed intake, feed conversion ratio, egg weight and egg mass of laying hens. The inclusion of glycerol in the diet of laying hens had no significant effect on egg specific gravity, eggshell breaking strength, eggshell weight, eggshell thickness, egg shape index, albumen index, yolk index, haugh unit, albumen pH, yolk pH and egg yolk colour values. The inclusion of glycerol in the diet of laying hens had no significant effect on palmitic, palmitoleic, stearic, oleic and linolenic acid contents of the egg yolk. The linoleic acid and polyunsaturated fatty acid contents of the egg yolk significantly decreased with the higher levels of dietary glycerol supplementation (P<0.05). The results of this study show that it is possible to replace 75% of soya bean oil (4.5% in diet) with glycerol. PMID:26365705

    celular. La influencia de las concentraciones de melaza y extracto acuoso de soya sobre la velocidad específica de crecimiento µ (h-1 de la cepa se estimó, variando las concentraciones de melaza en el medio Bradyfact de 3 a 20 g.L-1 y del extracto acuoso de soya de 5 a 20 g.L-1. Se obtuvieron las dinámicas de crecimiento para cada variante y se calculó la µ. Los resultados evidenciaron que concentraciones de melaza y extracto acuoso de soya superiores a 10,0 y 12,5 g.L-1, respectivamente, inhiben el crecimiento de Bradyrhizobium elkanii ICA 8001. Este fenómeno pudo ser explicado matemática y fisiológicamente mediante dos nuevos modelos cinéticos. Este trabajo contribuye al conocimiento de la fisiología de Bradyrhizobium, pues evidencia la relación entre la composición del medio de cultivo y los requerimientos nutricionales del microorganismo, así como el diseño del medio de cultivo puede garantizar la obtención de inoculantes más efectivos que contengan elevadas concentraciones celulares.

    This study was conducted to replace soya bean meal with maggot meal at difference percentages. A total of 120 one-day-old broiler chicks were divided into four groups. Four diets were formulated with maggot meal to replace soya bean meal at the rate of 0%, 10%, 20% and 30% designated as A, B, C and D respectively. Feed and water were offered ad libitum during the study which lasted for 28 days. Feed intake decreased significantly in treated groups while body weight, Feed conversion ratio and dressing percentage increased significantly in group D. Apparent metabolizable energy increased significantly in the group fed 30% maggot meal; however, no significant difference was found in dry matter, crude protein, crude fibre, ether extract, ash and nitrogen free extract between the control and treated groups. The result of sensory evaluation revealed that tenderness and juiciness increased significantly in group C and B respectively. The colour and flavour were most accepted in group B and C. The results indicate that replacement of soya bean meal at the rate of 30% in broiler feed produced most favourable results. PMID:26847519

    Performance assessments of jatropha, palm oil and soya bean based biodiesel were carried out to investigate their potential use as conventional substitute for kerosene for domestic purposes in rural- Ghana. The assessments were done by comparing some of the combustion characteristics of blends of the biodiesel with kerosene. The blends were categorised as B100 (100% biodiesel), B80 (80% biodiesel and 20% kerosene), B60 (60% biodiesel and 40% kerosene), B40 (40% biodiesel and 60% kerosene), B20 (20% biodiesel and 80% kerosene) and B0 (pure kerosene). The results showed that the calorific values of the B100s were less than that of the B0 and decreasing in the order of jatropha, soya bean and palm oil. The wick wastage results for both the B100s and B0, revealed higher rates in the WTL than the BB even though the BB recorded low fuel consumption rates than the WTL for both B100s and B0. Similarly, the luminous intensity test with the B100s showed low values in WTL than the BB in a decreasing order of jatropha, soya bean and palm oil. However, B0 recorded higher luminous intensity values that were quite comparable in both WTL and BB.

  19. Tolerance of VA Mycorrhizal Fungi to Soil Acidity

    Omueti, O; Morton, I D

    1996-01-01

    A nutritionally improved local snack compared to existing kokoro has been developed by extrusion cooking of different formulations of maize, soybean and condiments such as pepper, onion, salt, palm oil, plantain and banana. The improved snack was named as the 'soyabari snack stick'. The chemical composition of representative extruded products indicates a high level of crude protein, fat, energy, available lysine and improved in vitro digestibility compared to the usual maize-based products. The level of stachyose and raffinose were greatly reduced in the extruded products compared to raw soya. Formulations using various additives yielded products suitable for different consumers' preferences such as hot, sweet, bland, gritty or crispy and acceptable to taste assessors. Soyabari snack sticks were equally acceptable as Bombay mix, a product on the market in London. Sensory analysis showed no significant differences in the two products but the crude fibre content of Bombay mix was higher while the protein was slightly lower than for soyabari sticks. Local ingredients can produce acceptable extrudates. PMID:8616673

  7. The EU’s dependency on soya bean import for the animal feed industry and potential for EU produced alternatives

    Directory of Open Access Journals (Sweden)

    de Visser Cornelis Leonardus Maria

    2014-07-01

    Full Text Available The European Innovation Partnership Agri has set up a consultation process involving 20 experts from 11 EU countries to discuss the potential of a substantial increase in protein crop production in the EU. The dependency of Europe on soya bean meal imports and the associated drivers are described and underline the need for change. The EIP Agri process resulted in the assessment of the present-day yield gap of protein crops using an approach based on the market values of the protein, starch and plant oil components. Oil-based protein crops seemed to be overall better positioned than starch based protein crops because the price of oil levels is higher than that of starch. Alfalfa was identified as being interesting for regions where drying cost are low. The process also resulted in the identification of opportunities and constraints to be encountered by the innovation process, combining the knowledge and physical infrastructure, market structure, co-operation and interaction and the influence of culturally determined values and beliefs. Therefore, the recommendation is to develop a comprehensive approach to meet the challenge of substantially increasing the EU’s protein crop production.

  8. Use of γ-irradiation to produce films from whey, casein and soya proteins: structure and functionals characteristics

    International Nuclear Information System (INIS)

    γ-irradiation and thermal treatments have been used to produce sterilized cross-linked films. Formulations containing variable concentrations of calcium caseinate and whey proteins (whey protein isolate (WPI) and commercial whey protein concentrate) or mixture of soya protein isolate (SPI) with WPI was investigated on the physico-chemical properties of these films. Results showed that the mechanical properties of cross-linked films improved significantly the puncture strength for all types of films. Size-exclusion chromatography showed for no cross-linked proteins, a molecular mass of around 40 kDa. The soluble fractions of the cross-linked proteins molecular distributions were between 600 and 3800 kDa. γ-irradiation seems to modify to a certain extent the conformation of proteins which will adopt structures more ordered and more stable, as suggested by X-ray diffraction analysis. Microstructure observations showed that the mechanical characteristics of these films are closely related to their microscopic structure. Water vapor permeability of films based on SPI was also significantly decreased when irradiated. Microbial resistance was also evaluated for cross-linked films. Results showed that the level of biodegradation of cross-linked films was 36% after 60 d of fermentation in the presence of Pseudomonas aeruginosa

    Full Text Available The objective of this work was to study the effects of replacing Soybean meal by broad bean (Vicia faba L. in the formulation of concentrates on fermentation parameters in the rumen of Sicilo-Sarde rams. Parameters were pH, N-NH3 concentrations, protozoa, total gas and methane productions and in sacco digestibility of oat hay for different protein sources. Four Sicilo-Sarde rams with permanent canulas were used in this trial. Rams (mean age = 4.75±0.5; mean live weight = 53.3±6.6 kg were kept in individual boxes and received a ration distributed in two meals. The ration included 1.5 kg dry matter of oat hay and 500 g /ram/day of Soybean (S during one month and there after the broad bean (V during another one month period. Each of the trial periods was preceded by a two weeks adaptation period. Water was ad libitum. The S concentrate was 82.5% barley, 13.5% Soya, and 4% mineral mixture, while the F concentrate included 71.5% barley, 17.5% Vicia faba, 7% Soya and 4% mineral mixture. The energy and protein contents were 0.54, 0.96 and 0.96 UFV/kg DM and 5.20, 16.8 and 16.2 % for hay, S and V concentrates, respectively. Samples of 50 ml of rumen juice were taken before the morning meal and after 2, 5 and 8 hours to determine pH and ammonia nitrogen concentration. Types and counts of protozoa were determined on unfiltered rumen juice taken 2 hours after the morning meal and kept in a 100 ml fixing mixture. Protozoa types were counted by means of a HAWSKLEY counter. To determine gas production (CO and CH , rumen content was 2 4 collected in 100 ml plastic syringes before the morning meal and was filtered through four surgical gas layers. Rams were deprived from drinking water during the night before sampling. The DM degradability was determined by in sacco method using nylon bags with 50 micron diameter. Each bag contained 3 g of crushed hay and was incubated in the rumen for 48 hours. The pH of ruminal juice was comparable (P>0.05 for the S and V

  14. VaR: Exchange Rate Risk and Jump Risk

    Directory of Open Access Journals (Sweden)

    Fen-Ying Chen

    2010-01-01

    Full Text Available Incorporating the Poisson jumps and exchange rate risk, this paper provides an analytical VaR to manage market risk of international portfolios over the subprime mortgage crisis. There are some properties in the model. First, different from past studies in portfolios valued only in one currency, this model considers portfolios not only with jumps but also with exchange rate risk, that is vital for investors in highly integrated global financial markets. Second, in general, the analytical VaR solution is more accurate than historical simulations in terms of backtesting and Christoffersen's independence test (1998 for small portfolios and large portfolios. In other words, the proposed model is reliable not only for a portfolio on specific stocks but also for a large portfolio. Third, the model can be regarded as the extension of that of Kupiec (1999 and Chen and Liao (2009.

    Full Text Available In 2005, the Defense Advanced Research Projects Agency (DARPA announced its Revolutionizing Prosthetics program and funded the development of the DEKA prosthetic arm. The DEKA Arm System incorporates major technological advances such as flexible socket design, innovative control features, software, and hardware that together enable enhanced functionality that promises to surpass any currently available prosthetic device. In 2008, the Department of Veterans Affairs (VA entered into an agreement with DARPA to conduct clinical evaluations of the prototype DEKA Arm System, a prosthetic device system still under development and not yet available commercially. Studies of the DEKA Arm System have been underway at VA sites since late 2008, with the first subject fitted with a DEKA Arm in early 2009.

  16. American Indian veterans and VA services in three tribes.

    2016-01-01

    The purpose of this project was to describe experiences of reservation-based American Indian (AI) veterans with the Department of Veterans Affairs (VA), and to identify opportunities for improving care and services. Focus group discussions and individual interviews were conducted with AI veterans, family members, and community members in three diverse tribes. Results showed that many veterans in tribal communities experienced challenges receiving services and benefits from the VA, including lack of culturally competent care, transportation problems, and difficulties navigating the system. Family members, often main caregivers for AI veterans, lacked necessary resources, including sources for information, support services, and financial means to procure adequate care. A number of strengths also were identified, including local leadership and a strong community commitment to improve care for veterans. PMID:27115133

  17. Evaluation of stable isotope labelling strategies for the quantitation of CP4 EPSPS in genetically modified soya.

    The introduction of genetically modified (GM) crops into the market has raised a general alertness relating to the control and safety of foods. The applicability of protein separation hyphenated to mass spectrometry to identify the bacterial enolpyruvylshikimate-3-phosphate synthase (CP4 EPSPS) protein expressed in GM crops has been previously reported [M.F. Ocana, P.D. Fraser, R.K.P. Patel, J.M. Halket, P.M. Bramley, Rapid Commun. Mass Spectrom. 21 (2007) 319.]. Herein, we investigate the suitability of two strategies that employ heavy stable isotopes, i.e. AQUA and iTRAQ, to quantify different levels of CP4 EPSPS in up to four GM preparations. Both quantification strategies showed potential to determine whether the presence of GM material is above the limits established by the European Union. The AQUA quantification procedure involved protein solubilisation/fractionation and subsequent separation using SDS-PAGE. A segment of the gel in which the protein of interest was located was excised, the stable isotope labeled peptide added at a known concentration and proteolytic digestion initiated. Following recovery of the peptides, on-line separation and detection using LC-MS was carried out. A similar approach was used for the iTRAQ workflow with the exception that proteins were digested in solution and generated tryptic peptides were chemically tagged. Both procedures demonstrated the potential for quantitative detection at 0.5% (w/w) GM soya which is a level below the current European Union's threshold for food-labelling. In this context, a comparison between the two procedures is provided within the present study. PMID:19154813

  20. Water content of faeces is higher in the afternoon than in the morning in morning-fed dogs fed diets containing texturised vegetable protein from soya.

    Faecal moisture content can determine whether faeces appear soft or firm, and faecal character can influence whether owners are satisfied with a dog food. In a previous study, dogs appeared to produce softer faeces after noon. The purpose of the present study was to determine whether time of defecation affected canine faecal water content. A total of eight hound dogs were fed one of four canned diets as a single meal each morning for 1 week per diet in a Latin square design. All four diets contained approximately 77 % moisture and, on a DM basis, 24 MJ/kg gross energy, 23 % crude protein, 32 % crude fat, 31 % N-free extract and 1 % crude fibre. The proportion of dietary protein from soya-derived texturised vegetable protein (TVP):beef was 0:100, 14:86, 29:71 and 57:43, respectively. Soya carbohydrate partially replaced maize starch as TVP increased. Faeces were collected by direct catch during the sixth morning and afternoon of each diet period. Mean faecal moisture content was greater in the afternoon than in the morning (79 v. 71 %; P = 0.01) and increased with dietary TVP (P ≤ 0.0001), and there was an interaction between time of day and percentage TVP (P = 0.003). Faecal moisture content differed from morning to afternoon only with TVP in the diet. Faecal wet weight was similar from morning to afternoon. This suggests that time of day and presence of TVP from soya should be taken into account when evaluating the effect of a diet on faecal form and moisture content in dogs fed once daily.

  1. Soil persistence, plant and non-target insect uptake of endosulfan and lindane applied to soya bean and maize in field trials in Zimbabwe

    International Nuclear Information System (INIS)

    The persistence of lindane and endosulfan in the soil, uptake by, and distribution in plants, and effects on and absorption by non-target insects, following application of the insecticides for the control of maize pests and soya bean respectively were determined under Zimbabwean weather conditions. No large scale effects on the non-target insects were observed though some small effects on the populations of semiloopers and orthoptera in the endosulfan treated soya bean plot were noted. Concentrations of the insecticides in spiders declined during the trial though those in grasshoppers and crickets appeared to increase. Concentrations of both insecticides in soil fell rapidly during the first 7 weeks after application but, after that, the rates of loss were much slower possibly owing to the drier conditions prevailing during this later period, reducing both physicochemical and microbial loss processes. Initial concentrations of both insecticides in all the vegetative parts of plants examined after spray application declined systematically to low levels during the 10 weeks of observations, probably owing to both metabolism within the plants and to crop volume dilution effects and will have declined to even lower levels by harvest time. Surprisingly, low concentrations of lindane and endosulfan were found in the harvested maize and soya bean seeds. At early stages after application, there were also traces of both insecticides in the vegetative parts of the plants from the untreated, control plots probably arising from uptake of soil residues from the previous year and/or spray drift but these became undetectable at later stages of growth.

  3. VA paradigm shift in care of veterans with limb loss

    Directory of Open Access Journals (Sweden)

    Gayle E. Reiber, PhD, MPH

    2010-08-01

    Full Text Available Traumatic limb loss results in pain and discomfort in addition to the loss of an important part of the body and its function. The mental health challengesaccompanying limb loss include issues of frustration and body image, role in life, and feelings of not being whole. Many servicemembers and veteranswith limb loss need to prove to themselves that they can still accomplishphysical feats, such as those with lower-limb loss returning to running or those with upper-limb loss working with tools. If our servicemembers and veterans let these activities go, they again feel a loss. Therefore, Department of Veterans Affairs (VA services are available to help individuals meet their physical and recreational goals, whether they be running, walking, or masteringcomplex upper-limb activities. Veterans with limb loss need ongoing clinical care, prosthetic devices, and mobility assistance. As their prosthetic devices are repaired, replaced, and updated, they need corresponding educationand training. Too often in the past, the VA has taken a narrow view of amputation care, focusing only on managing prosthetic devices. Prosthetic care is one small but important aspect of the complex rehabilitation partnershipbetween the veteran with limb loss and the VA.

  4. Validation of KENO V.a: Comparison with critical experiments

    International Nuclear Information System (INIS)

    Section 1 of this report documents the validation of KENO V.a against 258 critical experiments. Experiments considered were primarily high or low enriched uranium systems. The results indicate that the KENO V.a Monte Carlo Criticality Program accurately calculates a broad range of critical experiments. A substantial number of the calculations showed a positive or negative bias in excess of 1 1/2% in k-effective (k/sub eff/). Classes of criticals which show a bias include 3% enriched green blocks, highly enriched uranyl fluoride slab arrays, and highly enriched uranyl nitrate arrays. If these biases are properly taken into account, the KENO V.a code can be used with confidence for the design and criticality safety analysis of uranium-containing systems. Sections 2 of this report documents the results of investigation into the cause of the bias observed in Sect. 1. The results of this study indicate that the bias seen in Sect. 1 is caused by code bias, cross-section bias, reporting bias, and modeling bias. There is evidence that many of the experiments used in this validation and in previous validations are not adequately documented. The uncertainty in the experimental parameters overshadows bias caused by the code and cross sections and prohibits code validation to better than about 1% in k/sub eff/. 48 refs., 19 figs., 19 tabs

    Women have participated in the United States military since its founding. However, until the mid-20th century, there had been limited recognition of women as official members of the military, and women remain a statistical minority within military and veteran populations. It is therefore important to better understand women's veteran identity (which we define here as one's self-concept as derived from their veteran status) and associated implications for service use and experiences in the Department of Veterans Affairs (VA) health care setting. The present research examined the centrality of, and positive regard for, women's veteran identity among 407 female veterans deployed in support of the recent wars in Iraq and Afghanistan. Data were collected via a mailed national survey. Positive regard for veteran identity, but not veteran identity centrality,was positively associated with participants' age and length of time spent in the military. Results also showed that the centrality of women's veteran identity was positively related to their choice to use VA for health care and their feelings of belonging within VA, and that veteran identity centrality and positive regard for veteran identity are differentially associated with participants' military experiences (e.g., combat exposure, deployment sexual harassment) and mental health symptomatology (e.g., depression).

    Full Text Available El cultivo de arroz siempre estuvo presente en el rol de culturas practicadas en el cerrado brasileño, en especial, en el Mato-grossense. Dado a esa particularidad, éste estudio busca comprender mejor las relaciones existentes entre la producción de arroz con las áreas plantadas de soya, y, propiamente, con la área plantada de arroz en Mato Grosso, en el período de 1979 a 2007. Debido a la gran extensión territorial del estado, el cultivo de arroz fue siendo realizado a lo largo de los años como frontera agrícola, para apertura de nuevas áreas, con variedades adecuadas a tierras, inicialmente, con baja fertilidad. Con el desarrollo tecnológico y la posibilidad de nuevas actividades productivas, esa realidad viene se alterando y la área plantada de arroz disminuyó a lo largo de los años, perdiendo espacio para la soya y pastos. Como instrumento metodológico, se empleó un modelo de regresión múltiple, estimada por el Método de Mínimos Cuadrados Ordinarios (MQO, en que los resultados apuntan las correlaciones existentes entre las categorías mencionadas, lo que permite analizar con más propiedad lo que está ocurriendo con el segmento. Las principales conclusiones obtenidas confirman la influencia positiva de la producción de arroz con relación a suya área plantada, sin embargo, negativa para las áreas plantadas de soya, pastos y arroz en Mato Grosso. Aunque venga perdiendo espacio para soya y pastos, el cultivo de arroz, mismo con menor productividad y calidad inferior del grano, aún es practicado debido a su capacidad de adaptación en nuevas áreas, o mismo, en áreas degradadas

    Full Text Available La roya asiática de la soya es una enfermedad importante tanto en Brasil como en el mundo; aunque han sido realizados muchos trabajos en este patosistema, no se conoce todavía una concentración ideal de inóculo para realizar investigaciones con la mencionada enfermedad en condiciones controladas. En este experimento, conducido en invernadero, se procuró identificar el umbral numérico de infección de Phakopsora pachyrhizi en folíolos de soya. Plantas de soya (cultivar Coodetec 214 rr fueron inoculadas con diferentes concentraciones (5x103, 10x103, 15x103, 20x103, 25x103 y 30x103 de uredosporas.ml-1 suspensos en agua. La intensidad de la enfermedad fue evaluada cuantificando la densidad de lesiones y de uredias en un área determinada de los folíolos centrales. Los datos fueron sometidos al análisis de varianza y de regresión, el mismo que mostró significación estadística p<0,01 y explicaron la respuesta biológica y matemática. Con las ecuaciones obtenidas de número de uredias.cm-2, lesiones. cm-2 y de la severidad estimada, se calculó que el número de uredosporas fue de 556 para formar una uredia.cm-2, 909 para formar una lesión.cm-2 y 2,500 para alcanzar 1% de severidad. A partir de las ecuaciones obtenidas en este trabajo, se puede seleccionar una concentración que resulte en una densidad deseada de lesiones y/o uredias de roya asiática de la soya en experimentos con inoculaciones artificiales. Asimismo, con la ecuación resultante de la relación entre número de uredias y lesiones por centímetro cuadrado, el investigador podrá escoger el método de cuantificación más razonable o confiable a su criterio, para trabajos con este patosistema.

  16. Process development for the removal and recovery of hazardous dye erythrosine from wastewater by waste materials-Bottom Ash and De-Oiled Soya as adsorbents

    International Nuclear Information System (INIS)

    Erythrosine is a water-soluble xanthene class of dye. It is widely used as colorant in foods, textiles, drugs and cosmetics. It is highly toxic, causes various types of allergies, thyroid activities, carcinogenicity, DNA damage behaviour, neurotoxicity and xenoestrogen nature in the humans and animals. The photochemical and biochemical degradation of the erythrosine is not recommended due to formation of toxic by-products. The present paper is an attempt to remove erythrosine from wastewater using adsorption over Bottom Ash-a power plant waste and De-Oiled Soya-an agricultural waste. Under the batch studies, effect of concentration of dye, temperature, pH of the solution, dosage of adsorbents, sieve size of adsorbents, etc., have been studied for the uptake of the dye over both adsorbents. The adsorption process verifies Langmuir and Freundlich adsorption isotherms in both the cases and based on the data different thermodynamic parameters have been evaluated. Batch studies also include kinetic measurements, rate constant study, mass transfer behaviour and establishment of mechanistic pathway for both the cases. For the bulk removal of the dye column operations have been carried out and breakthrough capacities of the Bottom Ash and De-Oiled Soya columns have been calculated. Attempts have also been made for the recovery of the adsorbed dye from exhausted columns by eluting dilute NaOH and more than 90% of the dye was recovered

  17. A comparison of the European renewable energy directive default emission values with actual values from operating biodiesel facilities for sunflower, rape and soya oil seeds in Italy

    International Nuclear Information System (INIS)

    The European Union (EU) set a binding greenhouse gas (GHG) emission reduction target for transportation biofuels and other bioliquids. In this study, the GHG emissions of biodiesel chain from sunflower, rapeseed and soybean were calculated in compliance with the European Union Renewable Energy Directive 2009/28/EC (RED). Input data used for the agricultural step were referred to the Umbrian region for sunflower and rapeseed and to the Veneto region for soybean, while data obtained from the main Italian biodiesel plants were employed for the processing step. Results showed that GHG emissions were higher than default values reported in the RED for sunflower and rapeseed and lower for soybean. Only sunflower biodiesel does not reach the minimum value of GHG saving (35%). The main differences with data used in the RED concern cultivation step, while the processing step has overall the same values of GHG emissions. Finally, three case studies were examined in order to identify possible improvements to make the analyzed supply chains more sustainable. -- Highlights: ► GHG balance of biodiesel from sunflower, rapeseed and soya was analyzed. ► Cultivation has the highest environmental impact for sunflower and rapeseed chains. ► Typical Italian data were adopted for cultivation and processing steps. ► GHG emissions were lower than RED default values for soya biodiesel. ► Cogeneration for the processing plant can greatly increase GHG saving.

  18. New Polish Certified Reference Materials for inorganic trace analysis: corn flour (INCT-CF-3) and soya bean flour (INCT-SBF-4)

    International Nuclear Information System (INIS)

    Preparation and certification of two new Polish reference materials (CRMs) for inorganic trace analysis: Corn Flour (INCT-CF-3) and Soya Bean Flour (INCT-SBF-4) have been presented. The materials were prepared and certified in the Institute of Nuclear Chemistry and Technology, Warsaw (INCT). Instrumental neutron activation analysis (INAA) was applied to homogeneity and stability studies. Homogeneity tests have shown that both materials are homogeneous for the sample mass 3 100 mg. The results of trend analysis have shown that the materials are stable. Uncertainty caused by instability and, consequently, shelf life of the materials have been estimated. Certification was based on the statistical evaluation of results obtained in worldwide interlaboratory comparison, in which 92 laboratories from 19 countries participated. Results for CRM distributed by the organizer and analyzed together with the intercomparison samples as well as results by definitive methods for selected elements based on radiochemical neutron activation analysis (RNAA) were also employed in the certification process. The contents of 16 and 22 elements were certified in Corn Flour and Soya Bean Flour, respectively. Additional information values for 14 elements in INCT-CF-3 and 9 elements in INCT-SBF-4 were given.

    We present our work towards using the Korean VLBI (Very Long Baseline Interferometer) Network (KVN) and VLBI Exploration of Radio Astronomy (VERA) arrays combined into the KVN and VERA Array (KaVA) for observations of radio pulsars at high frequencies ($\\simeq$22-GHz). Pulsar astronomy is generally focused at frequencies approximately 0.3 to several GHz and pulsars are usually discovered and monitored with large, single-dish, radio telescopes. For most pulsars, reduced radio flux is expected at high frequencies due to their steep spectrum, but there are exceptions where high frequency observations can be useful. Moreover, some pulsars are observable at high frequencies only, such as those close to the Galactic Center. The discoveries of a radio-bright magnetar and a few dozen extended Chandra sources within 15 arc-minute of the Galactic Center provide strong motivations to make use of the KaVA frequency band for searching pulsars in this region. Here, we describe the science targets and report progresses made...

  3. KENO V.a Primer: A Primer for Criticality Calculations with SCALE/KENO V.a Using CSPAN for Input

    Energy Technology Data Exchange (ETDEWEB)

    Busch, R.D.

    2003-01-17

    The SCALE (Standardized Computer Analyses for Licensing Evaluation) computer software system developed at Oak Ridge National Laboratory (ORNL) is widely used and accepted around the world for criticality safety analyses. The well-known KENO V.a three-dimensional Monte Carlo criticality computer code is the primary criticality safety analysis tool in SCALE. The KENO V.a primer is designed to help a new user understand and use the SCALE/KENO V.a Monte Carlo code for nuclear criticality safety analyses. It assumes that the user has a college education in a technical field. There is no assumption of familiarity with Monte Carlo codes in general or with SCALE/KENO V.a in particular. The primer is designed to teach by example, with each example illustrating two or three features of SCALE/KENO V.a that are useful in criticality analyses. The primer is based on SCALE 4.4a, which includes the Criticality Safety Processor for Analysis (CSPAN) input processor for Windows personal computers (PCs). A second edition of the primer, which uses the new KENO Visual Editor, is currently under development at ORNL and is planned for publication in late 2003. Each example in this first edition of the primer uses CSPAN to provide the framework for data input. Starting with a Quickstart section, the primer gives an overview of the basic requirements for SCALE/KENO V.a input and allows the user to quickly run a simple criticality problem with SCALE/KENO V.a. The sections that follow Quickstart include a list of basic objectives at the beginning that identifies the goal of the section and the individual SCALE/KENO V.a features which are covered in detail in the example problems in that section. Upon completion of the primer, a new user should be comfortable using CSPAN to set up criticality problems in SCALE/KENO V.a.

  5. Differential patterns of myosin Va expression during the ontogenesis of the rat hippocampus

    Directory of Open Access Journals (Sweden)

    L.S. Brinn

    2010-09-01

    Full Text Available Myosin Va is an actin-based, processive molecular motor protein highly enriched in the nervous tissue of vertebrates. It has been associated with processes of cellular motility, which include organelle transport and neurite outgrowth. The in vivo expression of myosin Va protein in the developing nervous system of mammals has not yet been reported. We describe here the immunolocalization of myosin Va in the developing rat hippocampus. Coronal sections of the embryonic and postnatal rat hippocampus were probed with an affinity-purified, polyclonal anti-myosin Va antibody. Myosin Va was localized in the cytoplasm of granule cells in the dentate gyrus and of pyramidal cells in Ammon's horn formation. Myosin Va expression changed during development, being higher in differentiating rather than already differentiated granule and pyramidal cells. Some of these cells presented a typical migratory profile, while others resembled neurons that were in the process of differentiation. Myosin Va was also transiently expressed in fibers present in the fimbria. Myosin Va was not detected in germinative matrices of the hippocampus proper or of the dentate gyrus. In conclusion, myosin Va expression in both granule and pyramidal cells showed both position and time dependency during hippocampal development, indicating that this motor protein is under developmental regulation.

    In this paper, value-at-risk (VaR for short) is used as the measure of risk. Based on the concept of VaR, a fuzzy mean-VaR model is proposed. Firstly, we recall some definitions and results of value-at-risk in credibilistic risk analysis. Secondly, we propose the fuzzy mean- VaR model of fuzzy programming, or more precisely, credibilistic programming. Thirdly, a hybrid intelligent algorithm is provided to give a general solution of the optimization problem. Finally, numerical examples are also presented to illustrate the effectiveness of the proposed algorithm.

    O'Brien, Charles P; McLellan, A Thomas; Childress, Anna Rose; Woody, George E

    2009-01-01

    The Penn/VA Center was founded in 1971 because of great concern over the number of Vietnam veterans returning home addicted to heroin. At that time little was known about the science of addiction, so our program from the very beginning was designed to gather data about the nature of addiction and measure the effects of available treatments. In other words, the goals were always a combination of treatment and research. This combination has continued to the present day. A human laboratory for the study of addiction phenomena such as conditioned responses was also founded in 1971. The key clinician investigators in this group have remained in the Center since the 1970s with most of the research staff continuing to work together. Important new investigators have been added over the years. Treatment was empirically based with randomized, controlled clinical trials as the gold standard for determining evidence-based treatment. The patients coming to treatment do not distinguish between abuse of alcohol and other drugs, so the treatment and research programs have always focused on all drugs including ethyl alcohol and the combination of ethyl alcohol with other drugs such as cocaine and opioids. Most of the patients coming for treatment also suffered from additional psychiatric disorders such as depression, anxiety, bipolar disorder or schizophrenia. Thus, the addiction treatment program in 1980 absorbed the rest of the VA Psychiatry Service into the Substance Abuse Program forming a new Behavioral Health Service with responsibility for over 9000 patients. The integration of substance abuse treatment with overall mental health care was the most efficient way to handle patients with complicated combinations of disorders. While this continues to be the best way to treat patients, it has proven difficult in practice. The main reason for this difficulty is that most mental health therapists whether they are psychiatrists, psychologists or social workers feel very inadequate

  9. Myosin Va is developmentally regulated and expressed in the human cerebellum from birth to old age

    Directory of Open Access Journals (Sweden)

    C.C.R. Souza

    2013-02-01

    Full Text Available Myosin Va functions as a processive, actin-based motor molecule highly enriched in the nervous system, which transports and/or tethers organelles, vesicles, and mRNA and protein translation machinery. Mutation of myosin Va leads to Griscelli disease that is associated with severe neurological deficits and a short life span. Despite playing a critical role in development, the expression of myosin Va in the central nervous system throughout the human life span has not been reported. To address this issue, the cerebellar expression of myosin Va from newborns to elderly humans was studied by immunohistochemistry using an affinity-purified anti-myosin Va antibody. Myosin Va was expressed at all ages from the 10th postnatal day to the 98th year of life, in molecular, Purkinje and granular cerebellar layers. Cerebellar myosin Va expression did not differ essentially in localization or intensity from childhood to old age, except during the postnatal developmental period. Structures resembling granules and climbing fibers in Purkinje cells were deeply stained. In dentate neurons, long processes were deeply stained by anti-myosin Va, as were punctate nuclear structures. During the first postnatal year, myosin Va was differentially expressed in the external granular layer (EGL. In the EGL, proliferating prospective granule cells were not stained by anti-myosin Va antibody. In contrast, premigratory granule cells in the EGL stained moderately. Granule cells exhibiting a migratory profile in the molecular layer were also moderately stained. In conclusion, neuronal myosin Va is developmentally regulated, and appears to be required for cerebellar function from early postnatal life to senescence.

    Full Text Available Una necesidad actual de la industria de extracción y refinación de aceite vegetal es la reducción y/o explotación de sus subproductos. Uno de estos, conocido como Ácidos Grasos Destilados de Aceite de Soya (AGDAS, resulta potencialmente valioso para las industrias alimentaria, farmacéutica y cosmética por la presencia de compuestos con actividad biológica favorable, como los fitoesteroles y el escualeno, los primeros como agentes hipocolesterolemiantes y el escualeno como emoliente y humectante. En este trabajo, mediante cromatografía de gases se determinó el contenido de escualeno y fitoesteroles libres y esterificados para evaluar la viabilidad de aprovechamiento de AGDAS como fuente de dichos compuestos y establecer si la procedencia del grano de soya (americano o nacional, la condición de cultivo (Sequía o Normal, años 2011 y 2012 respectivamente y el grado de calidad del aceite (Genérico o Premium son factores determinantes en el contenido de dichos compuestos en el subproducto. En conclusión AGDAS representa una fuente viable de fitoesteroles totales con 14.92% p/p, no así de escualeno con 1.75% p/p. La concentración de escualeno está influenciada por la procedencia del grano y la condición de cultivo, mientras que la de fitoesteroles esterificados por el grado de calidad y condición de cultivo. Ninguno de los factores influyó en el contenido de fitoesteroles totales. Esto permite establecer que la composición del subproducto AGDAS no es constante y se justifican protocolos como el de este estudio para su caracterización con fines de aprovechamiento.

  11. Empirical analysis on future-cash arbitrage risk with portfolio VaR

    Science.gov (United States)

    Chen, Rongda; Li, Cong; Wang, Weijin; Wang, Ze

    2014-03-01

    This paper constructs the positive arbitrage position by alternating the spot index with Chinese Exchange Traded Fund (ETF) portfolio and estimating the arbitrage-free interval of futures with the latest trade data. Then, an improved Delta-normal method was used, which replaces the simple linear correlation coefficient with tail dependence correlation coefficient, to measure VaR (Value-at-risk) of the arbitrage position. Analysis of VaR implies that the risk of future-cash arbitrage is less than that of investing completely in either futures or spot market. Then according to the compositional VaR and the marginal VaR, we should increase the futures position and decrease the spot position appropriately to minimize the VaR, which can minimize risk subject to certain revenues.

  12. Homeless and nonhomeless VA service users likely eligible for Medicaid expansion

    Directory of Open Access Journals (Sweden)

    Jack Tsai, PhD

    2014-09-01

    Full Text Available Administrative data on the population of Department of Veterans Affairs (VA service users in 2010 under the age of 65 yr (n = 3,841,225 were analyzed to identify the number and characteristics of homeless and nonhomeless VA service users who are likely to be eligible for the Medicaid expansion (LEME option under the Affordable Care Act. Results showed that, estimating conservatively, about 1.2 million (21% current VA users are LEME if all states implement the expansion. Homeless service users were twice as likely to be eligible than nonhomeless users (64% vs 30%. VA service users who are LEME, regardless of housing status, were physically healthier than those not LEME but were more likely to have substance use disorders and posttraumatic stress disorder. These findings suggest that many VA service users are LEME, particularly those who are homeless and/or have mental health needs. Cross-system use of VA and Medicaid-funded services may be advantageous for veterans with extensive medical and psychiatric needs but also risks fragmented care. Information and education for VA clinicians and their patients about possible implications of the Affordable Care Act may be important.

  13. Flexural Stiffness of Myosin Va Subdomains as Measured from Tethered Particle Motion.

    Science.gov (United States)

    2015-01-01

    Myosin Va (MyoVa) is a processive molecular motor involved in intracellular cargo transport on the actin cytoskeleton. The motor's processivity and ability to navigate actin intersections are believed to be governed by the stiffness of various parts of the motor's structure. Specifically, changes in calcium may regulate motor processivity by altering the motor's lever arm stiffness and thus its interhead communication. In order to measure the flexural stiffness of MyoVa subdomains, we use tethered particle microscopy, which relates the Brownian motion of fluorescent quantum dots, which are attached to various single- and double-headed MyoVa constructs bound to actin in rigor, to the motor's flexural stiffness. Based on these measurements, the MyoVa lever arm and coiled-coil rod domain have comparable flexural stiffness (0.034 pN/nm). Upon addition of calcium, the lever arm stiffness is reduced 40% as a result of calmodulins potentially dissociating from the lever arm. In addition, the flexural stiffness of the full-length MyoVa construct is an order of magnitude less stiff than both a single lever arm and the coiled-coil rod. This suggests that the MyoVa lever arm-rod junction provides a flexible hinge that would allow the motor to maneuver cargo through the complex intracellular actin network. PMID:26770194

  14. Effects of inspired CO2, hyperventilation, and time on VA/Q inequality in the dog

    Science.gov (United States)

    Tsukimoto, K.; Arcos, J. P.; Schaffartzik, W.; Wagner, P. D.; West, J. B.

    1992-01-01

    In a recent study by Tsukimoto et al. (J. Appl. Physiol. 68: 2488-2493, 1990), CO2 inhalation appeared to reduce the size of the high ventilation-perfusion ratio (VA/Q) mode commonly observed in anesthetized mechanically air-ventilated dogs. In that study, large tidal volumes (VT) were used during CO2 inhalation to preserve normocapnia. To separate the influences of CO2 and high VT on the VA/Q distribution in the present study, we examined the effect of inspired CO2 on the high VA/Q mode using eight mechanically ventilated dogs (4 given CO2, 4 controls). The VA/Q distribution was measured first with normal VT and then with increased VT. In the CO2 group at high VT, data were collected before, during, and after CO2 inhalation. With normal VT, there was no difference in the size of the high VA/Q mode between groups [10.5 +/- 3.5% (SE) of ventilation in the CO2 group, 11.8 +/- 5.2% in the control group]. Unexpectedly, the size of the high VA/Q mode decreased similarly in both groups over time, independently of the inspired PCO2, at a rate similar to the fall in cardiac output over time. The reduction in the high VA/Q mode together with a simultaneous increase in alveolar dead space (estimated by the difference between inert gas dead space and Fowler dead space) suggests that poorly perfused high VA/Q areas became unperfused over time. A possible mechanism is that elevated alveolar pressure and decreased cardiac output eliminate blood flow from corner vessels in nondependent high VA/Q regions.

    The effects of rapeseed and soya bean expeller (SBE) supplementation on digestion and milk production responses in dairy cows were investigated in an incomplete Latin square design using five cows and four 3-week periods. The experimental diets consisted of five concentrate treatments fed at a rate of 9 kg/day: a mixture of barley and oats, which was replaced with rapeseed or SBE at two levels (CP concentration (g/kg dry matter (DM)) of 130 for the control concentrate and 180 and 230 for the two protein supplemented levels). A mixture of grass and red clover silage (1:1) was fed ad libitum and it had a CP concentration of 157 g/kg DM. Supply of nutrients to the lower tract was measured using the omasal canal sampling technique, and total digestion from total faecal collection. Protein supplementation increased omasal canal amino acid (AA) flows and plasma concentrations of AA, and was also reflected as increased milk production. However, N use efficiency (NUE) decreased with increased protein supplementation. Rapeseed expeller (RSE) tended to increase silage DM intake and elicited higher milk production responses compared with SBE and also resulted in a higher NUE. The differences between the protein supplements in nitrogen metabolism were relatively small, for example, there were no differences in the efficiency of microbial protein synthesis or omasal canal flows of nitrogenous components between them, but plasma methionine concentration was lower for soya bean-fed cows at the high CP level in particular. The lower milk protein production responses to SBE than to RSE supplementation were at least partly caused by increased silage DM and by the lower methionine supply, which may further have been amplified by the use of red clover in the basal diet. Although feed intake, diet digestion, AA supply and milk production were all consistently improved by protein supplementation, there was a simultaneous decrease in NUE. In the current study, the milk protein production

They received diets based on either maize silage (M) or grass silage (G) (45% of diet on dry matter (DM) basis), with either soya bean meal (15% of diet DM) completed with beet pulp (15% of diet DM) (SP) or dehydrated lucerne (L) (30% of diet DM) as protein sources; MSP, ML, GSP and GL diets were calculated to meet energy requirements for milk production by dairy cows and degradable protein for rumen microbes. Dry matter intake (DMI) did not differ among diets (18.0 kg/day DMI); milk production was higher with SP diets than with L diets (26.0 v. 24.1 kg/day), but milk production did not vary with forage type. Milk fatty-acid (FA) composition was modified by both forage and protein sources: L and G diets resulted in less saturated FA, less linoleic acid, more trans-monounsaturated FA, and more linolenic acid than SP and M diets, respectively. Enteric methane (CH4) production, measured by the SF6 tracer method, was higher for G diets than for M diets, but did not differ with protein source. The same effects were observed when CH4 was expressed per kg milk. Minor effects of diets on rumen fermentation pattern were observed. Manure CH4 emissions estimated from faecal organic matter were negatively related to diet digestibility and were thus higher for L than SP diets, and higher for M than G diets; the resulting difference in total CH4 production was small. Owing to diet formulation constraints, N intake was higher for SP than for L diets; interaction between forage type and protein source was significant for N intake. The same statistical effects were found for N in milk. Faecal and urinary N losses were determined from total faeces and urine collection. Faecal N output was lower for M than for G diets but

    Cabedo and Moya [Cabedo, J.D., Moya, I., 2003. Estimating oil price 'Value at Risk' using the historical simulation approach. Energy Economics 25, 239-253] find that ARMA with historical simulation delivers VaR forecasts that are superior to those from GARCH. We compare the ARMA with historical simulation to the semi-parametric GARCH model proposed by Barone-Adesi et al. [Barone-Adesi, G., Giannopoulos, K., Vosper, L., 1999. VaR without correlations for portfolios of derivative securities. Journal of Futures Markets 19 (5), 583-602]. The results suggest that the semi-parametric GARCH model generates VaR forecasts that are superior to the VaR forecasts from the ARMA with historical simulation. This is due to the fact that GARCH captures volatility clustering. Our findings suggest that Cabedo and Moya's conclusion is mainly driven by the normal distributional assumption imposed on the future risk structure in the GARCH model. (author)

    2014-05-01

    The need to provide accurate value-at-risk (VaR) forecasting measures has triggered an important literature in econophysics. Although these accurate VaR models and methodologies are particularly demanded for hedge fund managers, there exist few articles specifically devoted to implement new techniques in hedge fund returns VaR forecasting. This article advances in these issues by comparing the performance of risk measures based on parametric distributions (the normal, Student’s t and skewed-t), semi-nonparametric (SNP) methodologies based on Gram-Charlier (GC) series and the extreme value theory (EVT) approach. Our results show that normal-, Student’s t- and Skewed t- based methodologies fail to forecast hedge fund VaR, whilst SNP and EVT approaches accurately success on it. We extend these results to the multivariate framework by providing an explicit formula for the GC copula and its density that encompasses the Gaussian copula and accounts for non-linear dependences. We show that the VaR obtained by the meta GC accurately captures portfolio risk and outperforms regulatory VaR estimates obtained through the meta Gaussian and Student’s t distributions.

    Full Text Available Background. Most genetic disorders are caused by single nucleotide variations (SNVs or small insertion/deletions (indels. High throughput sequencing has broadened the catalogue of human variation, including common polymorphisms, rare variations or disease causing mutations. However, identifying one variation among hundreds or thousands of others is still a complex task for biologists, geneticists and clinicians. Results. We have developed VaRank, a command-line tool for the ranking of genetic variants detected by high-throughput sequencing. VaRank scores and prioritizes variants annotated either by Alamut Batch or SnpEff. A barcode allows users to quickly view the presence/absence of variants (with homozygote/heterozygote status in analyzed samples. VaRank supports the commonly used VCF input format for variants analysis thus allowing it to be easily integrated into NGS bioinformatics analysis pipelines. VaRank has been successfully applied to disease-gene identification as well as to molecular diagnostics setup for several hundred patients. Conclusions. VaRank is implemented in Tcl/Tk, a scripting language which is platform-independent but has been tested only on Unix environment. The source code is available under the GNU GPL, and together with sample data and detailed documentation can be downloaded from http://www.lbgi.fr/VaRank/.

  7. Combination of soya protein and polydextrose reduces energy intake and glycaemic response via modulation of gastric emptying rate, ghrelin and glucagon-like peptide-1 in Chinese.

    The short-term effect of soya protein, polydextrose and their combination on energy intake (EI) was investigated in Chinese. In total, twenty-seven healthy, normotensive and lean Chinese men aged 21-40 years were given four different soyabean curd preloads with or without polydextrose. The study was a repeated-measure, randomised, cross-over design. The consumption of high-protein soyabean curd alone or in addition with polydextrose as a preload led to greater reduction in EI at a subsequent meal. A similar observation was also found after intake of low-protein soyabean curd with polydextrose. The gut hormone responses mirrored the reduction in food intake. It appears that incorporation of polydextrose either with low- or high-protein soyabean curd could be a potential strategy to reduce EI and assist with weight management. The popular consumption of soyabean curd in Chinese makes it an ideal vehicle for incorporation of polydextrose. This evidence-based dietary approach can serve as a guideline for developing functional foods for weight reduction and weight maintenance. PMID:27185412

  8. VA/Q distribution during heavy exercise and recovery in humans: implications for pulmonary edema

    Ventilation-perfusion (VA/Q) inequality has been shown to increase with exercise. Potential mechanisms for this increase include nonuniform pulmonary vasoconstriction, ventilatory time constant inequality, reduced large airway gas mixing, and development of interstitial pulmonary edema. We hypothesized that persistence of VA/Q mismatch after ventilation and cardiac output subside during recovery would be consistent with edema; however, rapid resolution would suggest mechanisms related to changes in ventilation and blood flow per se. Thirteen healthy males performed near-maximal cycle ergometry at an inspiratory PO2 of 91 Torr (because hypoxia accentuates VA/Q mismatch on exercise). Cardiorespiratory variables and inert gas elimination patterns were measured at rest, during exercise, and between 2 and 30 min of recovery. Two profiles of VA/Q distribution behavior emerged during heavy exercise: in group 1 an increase in VA/Q mismatch (log SDQ of 0.35 +/- 0.02 at rest and 0.44 +/- 0.02 at exercise; P less than 0.05, n = 7) and in group 2 no change in VA/Q mismatch (n = 6). There were no differences in anthropometric data, work rate, O2 uptake, or ventilation during heavy exercise between groups. Group 1 demonstrated significantly greater VA/Q inequality, lower vital capacity, and higher forced expiratory flow at 25-75% of forced vital capacity for the first 20 min during recovery than group 2. Cardiac index was higher in group 1 both during heavy exercise and 4 and 6 min postexercise. However, both ventilation and cardiac output returned toward baseline values more rapidly than did VA/Q relationships. Arterial pH was lower in group 1 during exercise and recovery. We conclude that greater VA/Q inequality in group 1 and its persistence during recovery are consistent with the hypothesis that edema occurs and contributes to the increase in VA/Q inequality during exercise. This is supported by observation of greater blood flows and acidosis and, presumably therefore

  9. Absence of platelet phenotype in mice lacking the motor protein myosin Va.

    Directory of Open Access Journals (Sweden)

    Matthew T Harper

    Full Text Available BACKGROUND: The motor protein myosin Va plays an important role in the trafficking of intracellular vesicles. Mutation of the Myo5a gene causes Griscelli syndrome type 1 in humans and the dilute phenotype in mice, which are both characterised by pigment dilution and neurological defects as a result of impaired vesicle transport in melanocytes and neuroendocrine cells. The role of myosin Va in platelets is currently unknown. Rab27 has been shown to be associated with myosin Va cargo vesicles and is known to be important in platelet dense granule biogenesis and secretion, a crucial event in thrombus formation. Therefore, we hypothesised that myosin Va may regulate granule secretion or formation in platelets. METHODOLOGY/PRINCIPAL FINDINGS: Platelet function was studied in vitro using a novel Myo5a gene deletion mouse model. Myo5a(-/- platelets were devoid of myosin Va, as determined by immunoblotting, and exhibited normal expression of surface markers. We assessed dense granule, α-granule and lysosomal secretion, integrin α(IIbβ(3 activation, Ca(2+ signalling, and spreading on fibrinogen in response to collagen-related peptide or the PAR4 agonist, AYPGKF in washed mouse platelets lacking myosin Va or wild-type platelets. Surprisingly, Myo5a(-/- platelets showed no significant functional defects in these responses, or in the numbers of dense and α-granules expressed. CONCLUSION: Despite the importance of myosin Va in vesicle transport in other cells, our data demonstrate this motor protein has no non-redundant role in the secretion of dense and α-granules or other functional responses in platelets.

  10. Interaction of blood coagulation factor Va with phospholipid vesicles examined by using lipophilic photoreagents

    International Nuclear Information System (INIS)

    Two different lipophilic photoreagents, [3H]adamantane diazirine and 3-(trifluoromethyl)-3-(m-[125I]iodophenyl)diazirine (TID), have been utilized to examine the interactions of blood coagulation factor Va with calcium, prothrombin, factor Xa, and, in particular, phospholipid vesicles. With each of these structurally dissimilar reagents, the extent of photolabeling of factor Va was greater when the protein was bound to a membrane surface than when it was free in solution. Specifically, the covalent photoreaction with Vl, the smaller subunit of factor Va, was 2-fold higher in the presence of phosphatidylcholine/phosphatidylserine (PC/PS, 3:1) vesicles, to which factor Va binds, than in the presence of 100% PC vesicles, to which the protein does not bind. However, the magnitude of the PC/PS-dependent photolabeling was much less than has been observed previously with integral membrane proteins. It therefore appears that the binding of factor Va to the membrane surface exposes Vl to the lipid core of the bilayer, but that only a small portion of the Vl polypeptide is exposed to, or embedded in, the bilayer core. Addition of either prothrombin or active-site-blocked factor Xa to PC/PS-bound factor Va had little effect on the photolabeling of Vl with TID, but reduced substantially the covalent labeling of Vh, the larger subunit of factor Va. This indicates that prothrombin and factor Xa each cover nonpolar surfaces on Vh when the macromolecules associate on the PC/PS surface. It therefore seems likely that the formation of the prothrombinase complex involves a direct interaction between Vh and factor Xa and between Vh and prothrombin.(ABSTRACT TRUNCATED AT 250 WORDS)

  13. Improving Memory Subsystem Performance Using ViVA: Virtual Vector Architecture

    2009-01-12

    The disparity between microprocessor clock frequencies and memory latency is a primary reason why many demanding applications run well below peak achievable performance. Software controlled scratchpad memories, such as the Cell local store, attempt to ameliorate this discrepancy by enabling precise control over memory movement; however, scratchpad technology confronts the programmer and compiler with an unfamiliar and difficult programming model. In this work, we present the Virtual Vector Architecture (ViVA), which combines the memory semantics of vector computers with a software-controlled scratchpad memory in order to provide a more effective and practical approach to latency hiding. ViVA requires minimal changes to the core design and could thus be easily integrated with conventional processor cores. To validate our approach, we implemented ViVA on the Mambo cycle-accurate full system simulator, which was carefully calibrated to match the performance on our underlying PowerPC Apple G5 architecture. Results show that ViVA is able to deliver significant performance benefits over scalar techniques for a variety of memory access patterns as well as two important memory-bound compact kernels, corner turn and sparse matrix-vector multiplication -- achieving 2x-13x improvement compared the scalar version. Overall, our preliminary ViVA exploration points to a promising approach for improving application performance on leading microprocessors with minimal design and complexity costs, in a power efficient manner.

  14. Point KENO V.a: A continuous-energy Monte Carlo code for transport applications

    International Nuclear Information System (INIS)

    KENO V.a is a multigroup Monte Carlo code that solves the Boltzmann transport equation and is used extensively in the criticality safety community to calculate the effective multiplication factor of systems with fissionable material. In this work, a continuous-energy or pointwise version of KENO V.a has been developed by first designing a new continuous-energy cross-section format and then by developing the appropriate Monte Carlo transport procedures to sample the new cross-section format. In order to generate pointwise cross sections for a test library, a series of cross-section processing modules were developed and used to process 50 ENDF/B-VI Release 7 nuclides for the test library. Once the cross-section processing procedures were in place, a continuous-energy version of KENO V.a was developed and tested by calculating 46 test cases that include critical and calculational benchmark problems. The Point KENO-calculated results for the test problems are in agreement with calculated results obtained with the multigroup version of KENO V.a and MCNP4C. Based on the calculated results with the prototypic cross-section library, a continuous-energy version of the KENO V.a code has been successfully developed and demonstrated for modeling systems with fissionable material.

Once the cross-section processing procedures were in place, a continuous-energy version of KENO V.a was developed and tested by calculating 21 critical benchmark experiments. The point KENO-calculated results for the 21 benchmarks are in agreement with calculated results obtained with the multigroup version of KENO V.a using the 238-group ENDF/B-5 and 199-group ENDF/B-6 Release 3 libraries. Based on the calculated results with the prototypic cross-section library, a continuous-energy version of the KENO V.a code has been successfully developed and demonstrated for modeling systems with fissionable material.

    Full Text Available Abstract Background Soya and its derivatives represent nutritionally high quality food products whose major drawback is their high content of α-galacto-oligosaccharides. These are not digested in the small intestine due to the natural absence of tissular α-galactosidase in mammals. The passage of these carbohydrates to the large intestine makes them available for fermentation by gas-producing bacteria leading to intestinal flatulence. The aim of the work reported here was to assess the ability of α-galactosidase-producing lactobacilli to improve the digestibility of α-galacto-oligosaccharides in situ. Results Gnotobiotic rats were orally fed with soy milk and placed in respiratory chambers designed to monitor fermentative gas excretion. The validity of the animal model was first checked using gnotobiotic rats monoassociated with a Clostridium butyricum hydrogen (H2-producing strain. Ingestion of native soy milk by these rats caused significant H2 emission while ingestion of α-galacto-oligosaccharide-free soy milk did not, thus validating the experimental system. When native soy milk was fermented using the α-galactosidase-producing Lactobacillus fermentum CRL722 strain, the resulting product failed to induce H2 emission in rats thus validating the bacterial model. When L. fermentum CRL722 was coadministered with native soy milk, a significant reduction (50 %, P = 0.019 in H2 emission was observed, showing that α-galactosidase from L. fermentum CRL722 remained active in situ, in the gastrointestinal tract of rats monoassociated with C. butyricum. In human-microbiota associated rats, L. fermentum CRL722 also induced a significant reduction of H2 emission (70 %, P = 0.004. Conclusion These results strongly suggest that L. fermentum α-galactosidase is able to partially alleviate α-galactosidase deficiency in rats. This offers interesting perspectives in various applications in which lactic acid bacteria could be used as a vector for

  19. Improvements in the vectorization of the KENO V.a criticality safety code

    International Nuclear Information System (INIS)

    A version of KENO V.a that takes advantage of the potential speedup inherent in vector processors is being developed at Oak Ridge National Laboratory (ORNL). The current version of KENO V.a tracks an individual particle history from source generation until it either leaks from the system or is killed, at which time the next particle history is processed. A vectorized Monte Carlo code tracks multiple particle histories simultaneously. Several new vectorized Monte Carlo particle-tracking codes have been developed, proving that significant speedups are possible, however, these new codes are either proprietary or not widely used. All new vectorized Monte Carlo Codes use an event-based algorithm in which all the particles undergoing a particular event are processed simultaneously. The vectorized version of KENO V.a currently being developed employs an event-based, event-driven, all-zone, tagged-particle algorithm

  20. EFFECTS OF VARIOUS SOIL ENVIRONMENTAL STRESSES ON THE OCCURRENCE, DISTRIBUTION AND EFFECTIVENESS OF VA MYCORRHIZAE

    Directory of Open Access Journals (Sweden)

    1995-01-01

    Full Text Available The vesicular - arbuscular (VA mycorrhizal fungi are geographically ubiquitous soil inhabitants and form universal symbiotic relationship with plants from every phylum. These fungi link host plants with host soils and their biota in the mycorrhizosphere and play an important role in plant health, productivity and soil structure. Although VA mycorrhizal fungi do not show any host specificity, there is increasing evidence that various climatic and edaphic environmental factors such as land use and management practices, physical, chemical and biological properties of host soils and host plant characteristics influence their occurrence, taxonomic distribution and effectiveness. The interaction of these factors with vesicular-arbuscular mycorrhizae (VAM is poorly understood except in a few cases. It is now very clear that VA mycorrhizal associations are ecologically significant factors that require more attention than previously accorded. This paper discusses the occurrence, distribution and significance of VAM in environmentally stressed soil conditions that limit plant growth such as drought, waterlogging and salinity.

  10. Computing Conditional VaR using Time-varying CopulasComputing Conditional VaR using Time-varying Copulas

    Beatriz Vaz de Melo Mendes

    2005-12-01

    Full Text Available It is now widespread the use of Value-at-Risk (VaR as a canonical measure at risk. Most accurate VaR measures make use of some volatility model such as GARCH-type models. However, the pattern of volatility dynamic of a portfolio follows from the (univariate behavior of the risk assets, as well as from the type and strength of the associations among them. Moreover, the dependence structure among the components may change conditionally t past observations. Some papers have attempted to model this characteristic by assuming a multivariate GARCH model, or by considering the conditional correlation coefficient, or by incorporating some possibility for switches in regimes. In this paper we address this problem using time-varying copulas. Our modeling strategy allows for the margins to follow some FIGARCH type model while the copula dependence structure changes over time.

  11. BMP-2 Overexpression Augments Vascular Smooth Muscle Cell Motility by Upregulating Myosin Va via Erk Signaling

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Background. The disruption of physiologic vascular smooth muscle cell (VSMC migration initiates atherosclerosis development. The biochemical mechanisms leading to dysfunctional VSMC motility remain unknown. Recently, cytokine BMP-2 has been implicated in various vascular physiologic and pathologic processes. However, whether BMP-2 has any effect upon VSMC motility, or by what manner, has never been investigated. Methods. VSMCs were adenovirally transfected to genetically overexpress BMP-2. VSMC motility was detected by modified Boyden chamber assay, confocal time-lapse video assay, and a colony wounding assay. Gene chip array and RT-PCR were employed to identify genes potentially regulated by BMP-2. Western blot and real-time PCR detected the expression of myosin Va and the phosphorylation of extracellular signal-regulated kinases 1/2 (Erk1/2. Immunofluorescence analysis revealed myosin Va expression locale. Intracellular Ca2+ oscillations were recorded. Results. VSMC migration was augmented in VSMCs overexpressing BMP-2 in a dose-dependent manner. siRNA-mediated knockdown of myosin Va inhibited VSMC motility. Both myosin Va mRNA and protein expression significantly increased after BMP-2 administration and were inhibited by Erk1/2 inhibitor U0126. BMP-2 induced Ca2+ oscillations, generated largely by a “cytosolic oscillator”. Conclusion. BMP-2 significantly increased VSMCs migration and myosin Va expression, via the Erk signaling pathway and intracellular Ca2+ oscillations. We provide additional insight into the pathophysiology of atherosclerosis, and inhibition of BMP-2-induced myosin Va expression may represent a potential therapeutic strategy.

  12. Physical stability of solid dispersions with respect to thermodynamic solubility of tadalafil in PVP-VA.

    2015-10-01

    The aim of this paper was to evaluate physical stability of solid dispersions in respect to the drug, tadalafil (Td), in vinylpyrrolidone and vinyl acetate block copolymer (PVP-VA). Nine solid dispersions of Td in PVP-VA (Td/PVP-VA) varied in terms of quantitative composition (1:9-9:1, w/w) were successfully produced by spray-drying. Their amorphous nature, supersaturated character and molecular level of mixing (a solid solution structure) were subsequently confirmed using DSC, PXRD, SEM and calculation of Hansen total solubility parameters. Due to thermal degradation of both components before the melting point of Td (302.3°C), an approach based on the drug crystallization from the supersaturated solid dispersion was selected to calculate the solubility of Td in the polymer. Annealing of the Td/PVP-VA solid dispersion (1:1, w/w) at selected temperatures above its Tg resulted in different stable solid dispersions. According to the Gordon-Taylor equation their new Tgs gave the information about the quantitative composition which corresponded to the thermodynamic solubility of Td in PVP-VA at given temperatures of annealing. The obtained relationship was fitted to the exponential function, with the calculated solubility of Td of 20.5% at 25°C. This value was in accordance with the results of hot stage polarizing light microscopy as well as stability tests carried out at 80°C and 0% RH, in which Td solid dispersions containing 10-20% of the drug were the only systems that did not crystallize within two months. A thermal analysis protocol utilizing a fast heating rate was shown to generate Td solubility data complementing the solid dispersion method. The Flory-Huggins model applied for the Td/PVP-VA system yielded the solubility value of 0.1% at 25°C, showing the lack of applicability in this case. PMID:26247119

    Cyberbullying among school-aged children has received increased attention in recent literature. However, no empirical evidence currently exists on whether existing school-based antibullying programs are effective in targeting the unique aspects of cyberbullying. To address this important gap, the present study investigates the unique effects of the KiVa Antibullying Program on the frequency of cyberbullying and cybervictimization among elementary and middle school youth. Using data from a group randomized controlled trial, multilevel ordinal regression analyses were used to examine differences in the frequencies of cyberbullying and cybervictimization between intervention (N = 9,914) and control students (N = 8,498). The effects of age and gender on frequencies of cyber behaviors were also assessed across conditions. Results revealed a significant intervention effect on the frequency of cybervictimization; KiVa students reported lower frequencies of cybervictimization at posttest than students in a control condition. The effect of condition on the perpetration of cyberbullying was moderated by age. When student age was below the sample mean, KiVa students reported lower frequencies of cyberbullying than students in the control condition. We also found evidence of classroom level variation in cyberbullying and cybervictimization, suggesting cyberbullying is in part a classroom-level phenomenon. KiVa appears to be an efficacious program to address cyber forms of bullying and victimization. We discuss several unique aspects of KiVa that may account for the significant intervention effects. Results suggest that KiVa is an intervention option for schools concerned with reducing cyberbullying behavior and its deleterious effects on children's adjustment. PMID:23659182

    Using frictional force microscopy (FFM), the friction surface characteristics were compared between twisted nematic (TN) mode and vertical alignment (VA) mode alignment films (AFs). The friction asymmetry was detected depending on temperature conditions on TN mode AF, but not on VA mode AF. The difference between two modes was explained by leaning intermolecular repulsion caused by the pre-tilt angle uniformity and the density of side chain. No level difference according to temperature conditions appeared when the pre-tilt angle were measured after liquid crystal (LC) injection.

  19. Contribution of Amino Acid Region 334−335 from Factor Va Heavy Chain to the Catalytic Efficiency of Prothrombinase†

    Science.gov (United States)

    2008-01-01

    We have demonstrated that amino acids E323, Y324, E330, and V331 from the factor Va heavy chain are required for the interaction of the cofactor with factor Xa and optimum rates of prothrombin cleavage. We have also shown that amino acid region 332−336 contains residues that are important for cofactor function. Using overlapping peptides, we identified amino acids D334 and Y335 as contributors to cofactor activity. We constructed recombinant factor V molecules with the mutations D334 → K and Y335 → F (factor VKF) and D334 → A and Y335 → A (factor VAA). Kinetic studies showed that while factor VaKF and factor VaAA had a KD for factor Xa similar to the KD observed for wild-type factor Va (factor VaWT), the clotting activities of the mutant molecules were impaired and the kcat of prothrombinase assembled with factor VaKF and factor VaAA was reduced. The second-order rate constant of prothrombinase assembled with factor VaKF or factor VaAA for prothrombin activation was ∼10-fold lower than the second-order rate constant for the same reaction catalyzed by prothrombinase assembled with factor VaWT. We also created quadruple mutants combining mutations in the amino acid region 334–335 with mutations at the previously identified amino acids that are important for factor Xa binding (i.e., E323Y324 and E330V331). Prothrombinase assembled with the quadruple mutant molecules displayed a second-order rate constant up to 400-fold lower than the values obtained with prothrombinase assembled with factor VaWT. The data demonstrate that amino acid region 334–335 is required for the rearrangement of enzyme and substrate necessary for efficient catalysis of prothrombin by prothrombinase. PMID:18537263

  20. Cooperative Regulation of the Activity of Factor Xa within Prothrombinase by Discrete Amino Acid Regions from Factor Va Heavy Chain†

    Science.gov (United States)

    2008-01-01

    The prothrombinase complex catalyzes the activation of prothrombin to α-thrombin. We have repetitively shown that amino acid region 695DYDY698 from the COOH terminus of the heavy chain of factor Va regulates the rate of cleavage of prothrombin at Arg271 by prothrombinase. We have also recently demonstrated that amino acid region 334DY335 is required for the optimal activity of prothrombinase. To assess the effect of these six amino acid residues on cofactor activity, we created recombinant factor Va molecules combining mutations at amino acid regions 334–335 and 695−698 as follows: factor V3K (334DY335 → KF and 695DYDY698 → KFKF), factor VKF/4A (334DY335 → KF and 695DYDY698 → AAAA), and factor V6A (334DY335 → AA and 695DYDY698 → AAAA). The recombinant factor V molecules were expressed and purified to homogeneity. Factor Va3K, factor VaK4/4A, and factor Va6A had reduced affinity for factor Xa, when compared to the affinity of the wild-type molecule (factor VaWt) for the enzyme. Prothrombinase assembled with saturating concentrations of factor Va3K had a 6-fold reduced second-order rate constant for prothrombin activation compared to the value obtained with prothrombinase assembled with factor VaWt, while prothrombinase assembled with saturating concentrations of factor VaKF/4A and factor Va6A had approximately 1.5-fold reduced second-order rate constants. Overall, the data demonstrate that amino acid region 334–335 together with amino acid region 695−698 from factor Va heavy chain are part of a cooperative mechanism within prothrombinase regulating cleavage and activation of prothrombin by factor Xa.

The two enzyme preparations were Enzyme R, a preparation extracted from fermentation of a non-GMO fungus Penicillum funiculosum, developed for multi-grain and multi-animal species; and Enzyme P, a xylanase preparation from Trichoderma longibrachiatum, for pigs fed corn-based diets only. Both enzymes were tested at 0, 0.25 and 0.50 g/kg feed using 70 crossbred male pigs (Large Yorkshire x Landrace) in five dietary treatments and seven replicates in each treatment, for growth period from 27 to 68 kg live weight in 49 days. Results showed that the supplementation of both enzymes (1) increased total-tract digestibility of dietary energy from 77.5% (control) to 81.4% (Enzyme R, p 0.05) and feed conversion ratio from 2.50 (control) to 2.42 (Enzyme R) and 2.36 (Enzyme P, p corn, soya bean meal and DLRM.

Se observó en ambos materiales la presencia de triterpenos, esteroides, quinonas, agrupamientos lactónicos, aminoácidos, aminas, lípidos, aceites, carbohidratos reductores, mucílagos, flavonoides y proteínas. La cuantificación de proteínas y carbohidratos reductores evidenció que el grano molido exhibe mayor concentración de ambos compuestos que la torta desgrasada.

  6. Adsorption isotherms, kinetics and column operations for the removal of hazardous dye, Tartrazine from aqueous solutions using waste materials-Bottom Ash and De-Oiled Soya, as adsorbents

    International Nuclear Information System (INIS)

    Adsorbents, Bottom Ash (a power plant waste) and De-Oiled Soya (an agricultural waste) exhibit good efficacy to adsorb a highly toxic dye, Tartrazine. Through the batch technique equilibrium uptake of the dye is observed at different concentrations, pH of the solution, dosage of adsorbents and sieve size of adsorbents. Langmuir and Freundlich adsorption isotherms are successfully employed on both the adsorbents and on the basis of these models the thermodynamic parameters are evaluated. Kinetic investigations reveal that more than 50% adsorption of dye is achieved in about 1 h in both the cases, whereas, equilibrium establishment takes about 3-4 h. The linear plots obtained in rate constant and mass transfer studies further confirm the applicability of first order rate expression and mass transfer model, respectively. The kinetic data treated to identify rate controlling step of the ongoing adsorption processes indicate that for both the systems, particle diffusion process is predominant at higher concentrations, while film diffusion takes place at lower concentrations. The column studies reveal that about 96% saturation of both the columns is attained during their exhaustion, while about 88 and 84% of the dye material is recovered by eluting dilute NaOH solution through exhausted Bottom Ash and De-Oiled Soya columns, respectively

    Risk measurement has both theoretical and practical significance in risk management. Using daily sample of 10 international stock indices, firstly this paper models the internal structures among different stock markets with C-Vine, D-Vine and R-Vine copula models. Secondly, the Value-at-Risk (VaR) and Expected Shortfall (ES) of the international stock markets portfolio are forecasted using Monte Carlo method based on the estimated dependence of different Vine copulas. Finally, the accuracy of VaR and ES measurements obtained from different statistical models are evaluated by UC, IND, CC and Posterior analysis. The empirical results show that the VaR forecasts at the quantile levels of 0.9, 0.95, 0.975 and 0.99 with three kinds of Vine copula models are sufficiently accurate. Several traditional methods, such as historical simulation, mean-variance and DCC-GARCH models, fail to pass the CC backtesting. The Vine copula methods can accurately forecast the ES of the portfolio on the base of VaR measurement, and D-Vine copula model is superior to other Vine copulas.

  9. Migration of epoxidised soya bean oil into foods from retail packaging materials and from plasticised PVC film used in the home.

    Castle, L; Mayo, A; Gilbert, J

    1990-01-01

    Epoxidised soya bean oil (ESBO) is used as a plasticiser and heat stabiliser in a number of feed contact materials, in particular in poly(vinyl chloride) (PVC) films and gaskets. The level of ESBO migration into foods has been determined using a combined gas chromatographic/mass spectrometric (GC/MS) analytical procedure. The study has included both the use of ESBO-containing materials for retail packaged foods and the domestic use of plasticised PVC films for applications such as wrapping food and covering food for re-heating in a microwave oven. Levels of ESBO in fresh retail meat samples wrapped in film ranged from less than 1 to 4 mg/kg, but were higher (max. 22 mg/kg) in retail cooked meat. Migration into sandwiches and rolls from 'take-away' outlets ranged from less than 1 to 27 mg/kg depending on factors such as the type of filling and the length of the contact time prior to analysis. The levels of migration of ESBO into cheese and cakes were consistent with previous experience with plasticiser migration--direct contact with fatty surfaces leading to the highest levels. When the film was used for microwave cooking in direct contact with food, levels of ESBO from 5 to 85 mg/kg were observed, whereas when the film was employed only as a splash cover for re-heating foods, ESBO levels ranged from 0.1 to 16 mg/kg. For a variety of baby foods there was no significant difference in ESBO levels between foods packaged in glass jars with PVC gaskets and foods in cans containing ESBO in the can lacquer. In both cases ESBO levels were low, ranging from less than 0.1 to 7.6 mg/kg. It is not clear for these retail samples, if the low levels observed (average 1.9 mg/kg) result solely from migration or contain some contribution from naturally occurring epoxides. PMID:2307263

El nivel de humedad afectó el rendimiento, peso de 100 semillas y porcentaje de germinación.; mientras que las profundidades de compactación restringieron más la profundidad de raíces. Los tratamientos no afectaron la altura de planta, área foliar, calidad de semilla, porcentaje de grasas y proteínas y toma de elementos (N, P, K, Ca, Mg, Mn, Zn, Cu, Fe y B.

     At Instituto Colombiano Agropecuario (ICA in Palmira, an experiment was carried out during the second semester of 1992 to evaluate the effect of different compaction depths and moisture levels on the soybean Valluna - 5 variety. On a loam soil without deficiencies nor toxicity of elements, the experiment was stablished under a split plot arrangement with four repetitions where the principal plots were the three irrigation levels and the subplots were the compaction depths (5, 15, 30 cm and  control. The moisture level was more influential than the compaction depth respect to the yield, weight of 100 seeds and germination percentage, while the compaction depth restricted more the root depth. Height of plants, foliar area, seed quality, oil and protein percentages and uptake of elements (N, P, K, Ca, MG, Mn, Zn, Cu, Fe and B were not affected by the treatments.

    RW has started the viability assessment (VA) effort to determine the feasibility of Yucca Mountain as the first geologic repository for spent nuclear fuel (SNF) and high-level waste. One component of the viability assessment will be a total system performance assessment (TSPA), based on the design concept and the scientific data and analysis available, describing the repository's probable behavior relative to the overall system performance standards. Thus, all the data collected from the Exploratory Studies Facility to-date have been incorporated into the latest TSPA model. In addition, the Repository Integration Program, an integrated probabilistic simulator, used in the TSPA has also been updated by Golder Associates Incorporated at December 1997. To ensure that the Department of Energy-owned (DOE-owned) SNF continues to be acceptable for disposal in the repository, it will be included in the TSPA-VA evaluation. A number of parameters are needed in the TSPA-VA models to predict the performance of the DOE-owned SNF materials placed into the potential repository. This report documents all of the basis and/or derivation for each of these parameters. A number of properties were not readily available at the time the TSPA-VA data was requested. Thus, expert judgement and opinion was utilized to determine a best property value. The performance of the DOE-owned SNF will be published as part of the TSPA-VA report. Each DOE site will be collecting better data as the DOE SNF program moves closer to repository license application. As required by the RW-0333P, the National Spent Nuclear Fuel Program will be assisting each site in qualifying the information used to support the performance assessment evaluations.

He was the first dean of the Faculty of History and the first head of the Department of History of the USSR (now the Department of History of Russia of Volgograd State University, reputable scientist, recognized expert in the history of the Russian social thought. The article shows the role of V.A. Kitaev in the formation and development of the faculty and the department. A characteristic of V.A. Kitaev’ sresearch and teaching activities is given. Kitaev’s featuresas a scholar and teacher such as great erudition, science scrupulosity, exactingness to himself andto his disciples, are marked. V.A. Kitaev worked at Volgograd State University for 16 years. All the while, he headed the Department andwas the dean for the first four years. The main thing is what he wanted in those positions – along with their colleagues was to lay and develop the traditions of the classical university, university atmosphere of the faculty and the university. The major scientific issues that are developed by V.A. Kitaev were: the history of liberalism and the fate of liberal reforms (modernization in Russia, the history of the Russian conservative thought, the problem of revolutionary violence as an inevitable result of the practical realization of socialist ideas. As an advocate of “establishing full-fledged liberal order”, V.A. Kitaev had, in essence, to ascertain: in Russia XIX – early XX century did not yet develop the historical conditions for the triumph of liberal ideas. The weakness and indecision of Russian liberals and their fear of the revolutionary movement, the constant fluctuation between the reform and reaction did not allow them to become independent of the political force that would determine the fate of the country in the end.

    Full Text Available Abstract Background More than half of veterans who use Veterans Health Administration (VA care are also eligible for Medicare via disability or age, but no prior studies have examined variation in use of outpatient services by Medicare-eligible veterans across health system, type of care or time. Objectives To examine differences in use of VA and Medicare outpatient services by disability-eligible or age-eligible veterans among veterans who used VA primary care services and were also eligible for Medicare. Methods A retrospective cohort study of 4,704 disability- and 10,816 age-eligible veterans who used VA primary care services in fiscal year (FY 2000. We tracked their outpatient utilization from FY2001 to FY2004 using VA administrative and Medicare claims data. We examined utilization differences for primary care, specialty care, and mental health outpatient visits using generalized estimating equations. Results Among Medicare-eligible veterans who used VA primary care, disability-eligible veterans had more VA primary care visits (p p p p p p Conclusions Greater use of primary care and specialty care visits by disability-eligible veterans is most likely related to greater health needs not captured by the patient characteristics we employed and eligibility for VA care at no cost. Outpatient care patterns of disability-eligible veterans may foreshadow care patterns of veterans returning from Afghanistan and Iraq wars, who are entering the system in growing numbers. This study provides an important baseline for future research assessing utilizations among returning veterans who use both VA and Medicare systems. Establishing effective care coordination protocols between VA and Medicare providers can help ensure efficient use of taxpayer resources and high quality care for disabled veterans.

  1. Multichannel spectroscopy system based on VA2TA front-end self-triggered chip

    International Nuclear Information System (INIS)

    An experimental prototype of a spectroscopy system that is based on 128-channel self-triggered VA2TA chip has been created. Software which allows registering and analyzing events in a multistrip silicon sensor has been developed. Main parameters of the measurement are defined in a program window and they control how the information from the connected channels is being processed. Low noise silicon planar and multistrip sensors have been bonded to the VA2TA chip and the energy resolution of the system has been tested. Spectra from 241Am, 57Co and characteristic X-ray radiation have been measured to test the energy resolution which was approximately 3.6...3.9 keV for a planar sensor for the energies in a range of 26...122 keV

    International Nuclear Information System (INIS)

    Tea (Camellia sinensis) seeds were sown on sterilized acidic yellow soil (pH 5.6) in a pot experiment and treated as follows: 1) inoculated with VA mycorrhizas fungus (Glomus citricolum), 2) nonmycorrhizal as control, top dressed with 32P-single superphosphate (M-32P) and 86Rb-rubidium chloride (M-86Rb). The results showed that the percentage of VA mycorrhizas infection was 52.6% for M-32P and 56.7% for M-86Rb. Plant height, dry weight and the uptake of phosphorus and potassium were 2.1 and 1.8 times, 2.4 and 2.5 times, 5.6 and 4.1 times as that of control respectively. The utilization rate of phosphorus and potassium were raised by 14.10% and 17.13% respectively

  3. A single phase model 9 kVA high-temperature superconducting power transformer

    International Nuclear Information System (INIS)

    A model 9 kVA (240 V/9.6 V) single-phase HTS transformer has been developed and tested with and without a cold iron core at 77 K. The primary and secondary windings were wound by transposed conductors, which are made from stainless steel-reinforced multifilamentary Bi2223/Ag tapes. The structures of the primary and secondary windings are helical and double-pancake, respectively. Primarily characteristics of the transformer are obtained through no-load tests, and short circuit tests. The iron cores are made of the common laminated Fe-Si steel plates and operate at nitrogen temperature 77 K. Based on the results of this transformer, we will develop a 630 kVA HTS transformer with the same rating currents in the near future

    Research and development on superconducting magnetic energy storage (SMES) system have been carried out to realize efficient electric power management for several decades. Korea Electrotechnology Research Institute (KERI) has developed a 3 MJ/750 kVA SMES system to improve power quality in sensitive electric loads. It consists of an IGBT based power converter, NbTi mixed matrix Rutherford cable superconducting magnet and a cryostat with HTS current leads. A computer code was developed to find the parameters of the SMES magnet which used minimum amount of superconductors for the same energy storage capability, and the 3 MJ SMES magnet was designed based upon that. This paper describes the fabrication and experimental results of the 3 MJ/750 kVA SMES system. (author)

    This national investigation utilizes qualitative data to evaluate an implementation model regarding factors influencing provider use of two evidence-based treatments for posttraumatic stress disorder (PTSD). Semi-structured qualitative interviews with 198 mental health providers from 38 Department of Veterans Affairs' (VA) residential treatment programs were used to explore these issues regarding prolonged exposure (PE) and cognitive processing therapy (CPT) in VA residential PTSD programs. Several unique and some overlapping predictors emerged. Leadership was viewed as an influence on implementation for both CPT and PE, while a lack of dedicated time and resources was viewed as a deterrent for both. Compatibility of CPT with providers' existing practices and beliefs, the ability to observe noticeable patient improvement, a perceived relative advantage of CPT over alternative treatments, and the presence of a supportive peer network emerged as influential on CPT implementation. Leadership was associated with PE implementation. Implications for the design and improvement of training and implementation efforts are discussed. PMID:24817625

    2016-02-01

    Reports an error in "Women's Veteran Identity and Utilization of VA Health Services" by Brooke A. L. Di Leone, Joyce M. Wang, Nancy Kressin and Dawne Vogt (Psychological Services, Advanced Online Publication, Mar 2, 2015, np). In the article, the institutional affiliation in the byline of Dawne Vogt did not include the National Center for PTSD. All versions of this article have been corrected. (The following abstract of the original article appeared in record 2015-09317-001.) Women have participated in the United States military since its founding. However, until the mid-20th century, there had been limited recognition of women as official members of the military, and women remain a statistical minority within military and veteran populations. It is therefore important to better understand women's veteran identity (which we define here as one's self-concept as derived from their veteran status) and associated implications for service use and experiences in the Department of Veterans Affairs (VA) health care setting. The present research examined the centrality of, and positive regard for, women's veteran identity among 407 female veterans deployed in support of the recent wars in Iraq and Afghanistan. Data were collected via a mailed national survey. Positive regard for veteran identity, but not veteran identity centrality, was positively associated with participants' age and length of time spent in the military. Results also showed that the centrality of women's veteran identity was positively related to their choice to use VA for health care and their feelings of belonging within VA, and that veteran identity centrality and positive regard for veteran identity are differentially associated with participants' military experiences (e.g., combat exposure, deployment sexual harassment) and mental health symptomatology (e.g., depression).

  11. KENO3D, Visualisation Tool for KENO V.A and KENO-VI Geometry Models

    International Nuclear Information System (INIS)

    1 - Description of program or function: The KENO3D Visualization Tool for KENO Geometry Models is a powerful state-of-the-art visualization tool that enables KENO V.a users and KENO-VI to interactively display their three-dimensional geometry models. The KENO3D interactive options include: - Shaded or wire-frame images ; - Standard views such as top view, side view, front view, and isometric(3-D) view; - Rotating the model ; - Zooming in on selected locations ; - Selecting parts of the model to display ; - Editing colors and displaying legends ; - Displaying properties of any unit in the model ; - Creating cut-away views ; - Removing units from the model; - Printing image or saving image to a common graphics formats. KENO3D was developed for use by criticality safety specialists that use the KENO three-dimensional Monte Carlo criticality computer code. KENO V.a and KENO-VI are part of the SCALE (Standardized Computer Analyses for Licensing Evaluations) computer software system developed at Ridge National Laboratory (ORNL) that is widely used and accepted around the world for criticality safety analyses. 2 - Methods: KENO3D reads CSAS, KENO V.a, or KENO-VI input files. It attempts to verify that the KENO geometry input is 'legal', i.e., it conforms to the code input guidelines. KENO3D prints a warning message for illegal geometry input, and if possible, it displays the illegal KENO geometry to facilitate debugging of the input. Problems with more than 300,000 KENO V.a bodies have been successfully tested and displayed. KENO3D has the look and feel of a typical PC Windows application. Toolbar buttons are included for all major menu options. There is a setup dialog that allows the user to specify toolbars that should be displayed

    Konstantinos Pelechrinis

    Full Text Available Network connections have been shown to be correlated with structural or external attributes of the network vertices in a variety of cases. Given the prevalence of this phenomenon network scientists have developed metrics to quantify its extent. In particular, the assortativity coefficient is used to capture the level of correlation between a single-dimensional attribute (categorical or scalar of the network nodes and the observed connections, i.e., the edges. Nevertheless, in many cases a multi-dimensional, i.e., vector feature of the nodes is of interest. Similar attributes can describe complex behavioral patterns (e.g., mobility of the network entities. To date little attention has been given to this setting and there has not been a general and formal treatment of this problem. In this study we develop a metric, the vector assortativity index (VA-index for short, based on network randomization and (empirical statistical hypothesis testing that is able to quantify the assortativity patterns of a network with respect to a vector attribute. Our extensive experimental results on synthetic network data show that the VA-index outperforms a baseline extension of the assortativity coefficient, which has been used in the literature to cope with similar cases. Furthermore, the VA-index can be calibrated (in terms of parameters fairly easy, while its benefits increase with the (co-variance of the vector elements, where the baseline systematically over(underestimate the true mixing patterns of the network.

    2010-10-01

    Full Text Available The Department of Veterans Affairs (VA provides integrated services to more than 25,000 veterans with spinal cord injuries and disorders (SCI/D. VA data offer great potential for providing insights into healthcare utilization and morbidity, and these capabilities are central to efforts to improve healthcare for veterans with SCI/D. The objective of this article is to introduce researchers to the use of VA data to examine questions related to SCI/D using examples from Spinal Cord Injury (SCI Quality Enhancement Research Initiative studies. Sources of VA data available to investigators interested in SCI/D-related research include national-level VA administrative and clinical databases and primary data (medical record review, patient surveys. Methods used to identify veterans with SCI/D include the Allocation Resource Center cohort, the Spinal Cord Dysfunction (SCD Registry, and the VA inpatient SCI flag; only 33% of veterans were included in all three groups (n = 12,306. While neurological level of SCI was unknown for approximately a third of veterans (from SCD Registry data alone, the percent decreased to 13% when augmented with diagnostic codes. Primary data can be used to augment other missing SCI data and to provide more detailed information about complications commonly associated with SCI/D.

  14. Adenovirus Vector-Derived VA-RNA-Mediated Innate Immune Responses

    Full Text Available The major limitation of the clinical use of replication-incompetent adenovirus (Ad vectors is the interference by innate immune responses, including induction of inflammatory cytokines and interferons (IFN, following in vivo application of Ad vectors. Ad vector-induced production of inflammatory cytokines and IFNs also results in severe organ damage and efficient induction of acquired immune responses against Ad proteins and transgene products. Ad vector-induced innate immune responses are triggered by the recognition of Ad components by pattern recognition receptors (PRRs. In order to reduce the side effects by Ad vector-induced innate immune responses and to develop safer Ad vectors, it is crucial to clarify which PRRs and which Ad components are involved in Ad vector-induced innate immune responses. Our group previously demonstrated that myeloid differentiating factor 88 (MyD88 and toll-like receptor 9 (TLR9 play crucial roles in the Ad vector-induced inflammatory cytokine production in mouse bone marrow-derived dendritic cells. Furthermore, our group recently found that virus associated-RNAs (VA-RNAs, which are about 160 nucleotide-long non-coding small RNAs encoded in the Ad genome, are involved in IFN production through the IFN-β promoter stimulator-1 (IPS-1-mediated signaling pathway following Ad vector transduction. The aim of this review is to highlight the Ad vector-induced innate immune responses following transduction, especially VA-RNA-mediated innate immune responses. Our findings on the mechanism of Ad vector-induced innate immune responses should make an important contribution to the development of safer Ad vectors, such as an Ad vector lacking expression of VA-RNAs.

    Ethylene vinyl acetate (EVA) copolymers with two different VA contents (15 and 33 wt.%, denoted by EVA15 and EVA33, respectively) were melt compounded with multi-walled carbon nanotubes (MWNTs) and the effect of VA and nanotube contents on the rheological, thermal and morphological properties was investigated. The addition of nanotubes into both EVAs increased the onset temperature of crystallization and broadened the peak, but further addition from 3 wt.% slightly decreased the temperature with increasing nanotube contents. In the wide angle X-ray diffraction patterns the peak of EVA15 was little affected by the presence of nanotubes but that of EVA33 slightly shifted to higher degree and became sharper with increasing nanotube contents. Dynamic viscosity (η') increased with nanotube contents giving abrupt increase at 2 wt.% nanotubes. Loss tangent decreased with increasing nanotube contents exhibiting the plateau-like behavior over most of the frequency range from 2 wt.% nanotubes. In the Casson plot, yield stress increased with nanotube content and its increasing extent was more notable for more VA content. In the Cole-Cole plot, the presence of nanotubes from 2 wt.% gave rise to the deviation from the single master curve by decreasing the slope. The deviated extent of EVA33 became more remarkable with increasing nanotube contents than that of EVA15. The stress-strain curve showed that more improved tensile modulus and yield stress were achieved by the introduction of MWNTs for EVA 33 than for EVA15. Tensile strength of EVA33 increased with increasing nanotube contents, while that of EVA15 decreased.

  1. Development and test of a 100 kVA superconducting transformer operated at 77 K

    International Nuclear Information System (INIS)

    High-temperature superconducting (HTS) transformers are very promising candidates for application in electrical power engineering. Their main advantages are reduced size, weight, better efficiency and reduced potential fire and environmental hazards. We have designed, constructed and tested a 100 kVA HTS power transformer operated at 77 K. The nominal primary and secondary currents (voltages) are 18 A (5.6 kV) and 92 A (1.1 kV), respectively. No-load tests, short-circuit tests and load tests proved repeatedly that the transformer has the rated capacity. HTS winding losses of 20.6 W and iron losses of 403 W were measured. (author)

    Full Text Available VaR (Value at Risk and CVaR (Conditional Value at Risk are implied by option prices. Their relationships to option prices are derived initially under the pricing measure. It does not require assumptions about the distribution of portfolio returns. The effects of changes of measure are modest at the short horizons typically used in applications. The computation of CVaR from option price is very convenient, because this measure is not elicitable, making direct comparisons of statistical inferences from market data problematic.

    The Korean very-long-baseline interferometry (VLBI) network (KVN) and VLBI Exploration of Radio Astrometry (VERA) Array (KaVA) is the first international VLBI array dedicated to high-frequency (23 and 43 GHz bands) observations in East Asia. Here, we report the first imaging observations of three bright active galactic nuclei (AGNs) known for their complex morphologies: 4C 39.25, 3C 273, and M 87. This is one of the initial result of KaVA early science. Our KaVA images reveal extended outflows with complex substructure such as knots and limb brightening, in agreement with previous Very Long Baseline Array (VLBA) observations. Angular resolutions are better than 1.4 and 0.8 milliarcsecond at 23 GHz and 43 GHz, respectively. KaVA achieves a high dynamic range of ~1000, more than three times the value achieved by VERA. We conclude that KaVA is a powerful array with a great potential for the study of AGN outflows, at least comparable to the best existing radio interferometric arrays.

    Interest in animal assisted interventions (AAI) has grown over the years, but acceptance of AAI by the clinical and research community has been hampered by safety, hygiene, and logistical concerns. Advances in the field of social robotics have provided a promising route to deliver AAI while avoiding these aforementioned obstacles. Although there has been promising initial research on social robotics in older adults, to date there has been no such research conducted with a veteran population. The present pilot study followed 23 veteran residents of a Veterans Affairs (VA) geropsychiatric long-term care facility over the span of approximately a year and a half. It was found that use of Paro, a social robot, resulted in increased observed positive affective and behavioral indicators, with concomitant decreases observed in negative affective and behavioral indicators. The authors concluded that Paro is likely an effective nonpharmacological approach for managing dementia-related mood and behavior problems with veterans in VA long term care facilities. They additionally observed that Paro is best presented to residents who are relatively calm and approachable, as opposed to actively exhibiting behavior or mood problems. Future research directions are discussed in light of both the positive results noted and the inherent limitations of our pilot study. (PsycINFO Database Record PMID:27195530

    There has been intensive interest to ensure equitable and appropriate access to the specialized rehabilitative services of the VA Polytrauma System of Care (PSC) for patients sustaining polytrauma and traumatic brain injuries (TBI). A retrospective cohort study with prospective data acquisition was conducted to assess validity and objectivity of the acceptance decision algorithm to the VA Palo Alto Health Care System (VAPAHCS) PSC. Our hypotheses are (1) VAPAHCS PSC referral decisions were appropriate and without bias and (2) the identified needs of redirected referrals were addressed. This analysis included 1,025 referrals (906 patients); 813 patients (89.7%) were accepted, and 93 (10.3%) were redirected. Redirected cases were older, were more often active duty service members, and were not from the West Coast. There were more females redirected due to concomitant spinal cord injury. These are rationale differences. In redirected patients, the most commonly identified rehabilitation needs were psychological support, mobility/physical therapy, and communication/speech services; >75% of patients had these services offered elsewhere outside of the PSC resources. While balancing financial stewardship and meeting our mission to provide outstanding rehabilitative care to veterans and service members, we demonstrated that acceptance decisions were valid and without bias, and redirected patients received appropriate alternate resources.

    The Health Services Research and Development (HSR&D) Service at the Department of Veterans Affairs (VA) Health Care System launched a Quality Enhancement Research Initiative (QUERI) in 1998. This study estimated health-care costs of nine diseases under the QUERI project and analyzed geographic differences in health-care costs and utilization across 22 VA Integrated Service Networks (VISNs), using a geographic information system (GIS). Patients with these diseases were identified from diagnoses recorded between October 1999 and September 2000. Annual health-care costs for each disease were estimated in four categories: inpatient medical or surgical, other inpatient, outpatient, and outpatient pharmacy. Geographic differences of costs and health-care utilization across the 22 VISNs for chronic heart failure, diabetes, and spinal-cord injury were mapped using a GIS package. Average costs and patterns of health-care utilization varied substantially across the 22 VISNs. The observed differences in health-care utilization across geographic regions raised questions for further investigation. PMID:15446617

    Full Text Available Measuring risk of financial institutes and banks plays an important role on managing them. Recent financial turmoil in United States banking system has motivated banking industry to monitor risk factors more closely. In this paper, we present an empirical study to measure the risk of some private banks in Iran called Bank Mellat using Value at Risk (VaR method. The proposed study collects the necessary information for the fiscal year of 2010 and analyses them using regression analysis. The study divides the financial data into two groups where the financial data of the first half of year is considered in the first group and the remaining information for the second half of year 2010 is considered in the second group. The implementation of VaR method indicates that financial risks increase during the time horizon. The study also uses linear regression method where independent variable is time, dependent variable is the financial risk, and the results confirm what we have found in the previous part of the survey.

    Recent research has documented high rates of comorbidity between cannabis use disorders and posttraumatic stress disorder (PTSD) in veterans. However, despite possible links between PTSD and cannabis use, relatively little is known about cannabis use in veterans who present for PTSD treatment, particularly among samples not diagnosed with a substance use disorder. This study examined the prevalence of cannabis use and the psychological and functional correlates of cannabis use among a large sample of veterans seeking treatment at a Veterans Affairs (VA) PTSD specialty clinic. Male veterans (N = 719) who presented at a VA specialty outpatient PTSD clinic completed measures of demographic variables, combat exposure, alcohol, cannabis and other drug use, and PTSD and depressive symptoms. The associations among demographic, psychological, and functional variables were estimated using logistic regressions. Overall, 14.6% of participants reported using cannabis in the past 6 months. After controlling for age, race, service era, and combat exposure, past 6-month cannabis use was associated with unmarried status, use of tobacco products, other drug use, hazardous alcohol use, PTSD severity, depressive symptom severity, and suicidality. The present findings show that cannabis use is quite prevalent among veterans seeking PTSD specialty treatment and is associated with poorer mental health and use of other substances. It may be possible to identify and treat individuals who use cannabis in specialty clinics (e.g., PTSD clinics) where they are likely to present for treatment of associated mental health issues.

    Research on school-based prevention suggests that the success of prevention programs depends on whether they are implemented as intended. In antibullying program evaluations, however, limited attention has been paid to implementation fidelity. The present study fills in this gap by examining the link between the implementation of the KiVa antibullying program and outcome. With a large sample of 7413 students (7-12years) from 417 classrooms within 76 elementary schools, we tested whether the degree of implementation of the student lessons in the KiVa curriculum was related to the effectiveness of the program in reducing bullying problems in classrooms. Results of multilevel structural equation modeling revealed that after nine months of implementation, lesson adherence as well as lesson preparation time (but not duration of lessons) were associated with reductions in victimization at the classroom level. No statistically significant effects, however, were found for classroom-level bullying. The different outcomes for victimization and bullying as well as the importance of documenting program fidelity are discussed. PMID:25267170

    Full Text Available Since it was first reported in Brazil in the 1990s, the B biotype of silverleaf whitefly (Bemisia tabaci Genn., Hemiptera: Aleyrodidae has been recognized as an important pest in soybeans (Glycine max L., reducing the productivity of this legume species in some areas of the country. As an alternative to chemical control, the use of resistant genotypes represents an important tool for integrated pest management (IPM. This study evaluated the performance of 10 soybean genotypes prior to whitefly infestation, by testing attractiveness and preference for oviposition in the greenhouse and antibiosis in the laboratory. In a multiple-choice test, 'IAC-17' was the least attractive to insects. In a no-choice test, 'IAC-17' was the least attractive for egg deposition, indicating the occurrence of non-preference for oviposition on this genotype. Trichome density was positively correlated with the oviposition site and may be associated with the resistance of 'IAC-17' to infestation. The genotypes 'IAC-PL1', 'IAC-19', 'Conquista', 'IAC-24' and 'IAC-17' extended the insect's life cycle, indicating the occurrence of a small degree of antibiosis and/or non-preference for feeding.Desde que se registró por primera vez en Brasil en la década de 1990, el biotipo B de la mosca-blanca (Bemisia tabaci Genn., Hemiptera: Aleyrodidae, se reconoce como una importante plaga de la soya (Glycine max L. y es lo que reduce la productividad de estas especies de leguminosas en algunas zonas del pais.

    Full Text Available We investigate the relative performance of a wide array of Value at Risk (VaR models with the daily returns of Turkish (XU100 and Croatian (CROBEX stock index prior to and during the ongoing financial crisis. In addition to widely used VaR models, we also study the behaviour of conditional and unconditional extreme value theory (EVT and hybrid historical simulation (HHS models to generate 95, 99 and 99.5% confidence level estimates. Results indicate that during the crisis period all tested VaR model except EVT and HHS models seriously underpredict the true level of risk, with EVT models doing so at a higher cost of capital compared to HHS model

  20. Myosin Va plays a role in nitrergic smooth muscle relaxation in gastric fundus and corpora cavernosa of penis.

    Directory of Open Access Journals (Sweden)

    Arun Chaudhury

    Full Text Available The intracellular motor protein myosin Va is involved in nitrergic neurotransmission possibly by trafficking of neuronal nitric oxide synthase (nNOS within the nerve terminals. In this study, we examined the role of myosin Va in the stomach and penis, proto-typical smooth muscle organs in which nitric oxide (NO mediated relaxation is critical for function. We used confocal microscopy and co-immunoprecipitation of tissue from the gastric fundus (GF and penile corpus cavernosum (CCP to localize myosin Va with nNOS and demonstrate their molecular interaction. We utilized in vitro mechanical studies to test whether smooth muscle relaxations during nitrergic neuromuscular neurotransmission is altered in DBA (dilute, brown, non-agouti mice which lack functional myosin Va. Myosin Va was localized in nNOS-positive nerve terminals and was co-immunoprecipitated with nNOS in both GF and CCP. In comparison to C57BL/6J wild type (WT mice, electrical field stimulation (EFS of precontracted smooth muscles of GF and CCP from DBA animals showed significant impairment of nitrergic relaxation. An NO donor, Sodium nitroprusside (SNP, caused comparable levels of relaxation in smooth muscles of WT and DBA mice. These normal postjunctional responses to SNP in DBA tissues suggest that impairment of smooth muscle relaxation resulted from inhibition of NO synthesis in prejunctional nerve terminals. Our results suggest that normal physiological processes of relaxation of gastric and cavernosal smooth muscles that facilitate food accommodation and penile erection, respectively, may be disrupted under conditions of myosin Va deficiency, resulting in complications like gastroparesis and erectile dysfunction.

    Full Text Available Background: Assessing the progress in achieving the United Nation's Millennium Development Goals in terms of population health requires consistent and reliable information on cause-specific mortality, which is often rare in resource-constrained countries. Health and demographic surveillance systems (HDSS have largely used medical personnel to review and assign likely causes of death based on the information gathered from standardized verbal autopsy (VA forms. However, this approach is expensive and time consuming, and it may lead to biased results based on the knowledge and experience of individual clinicians. We assessed the cause-specific mortality for children under 5 years old (under-5 deaths in Siaya County, obtained from a computer-based probabilistic model (InterVA-4. Design: Successfully completed VA interviews for under-5 deaths conducted between January 2003 and December 2010 in the Kenya Medical Research Institute/US Centers for Disease Control and Prevention HDSS were extracted from the VA database and processed using the InterVA-4 (version 4.02 model for interpretation. Cause-specific mortality fractions were then generated from the causes of death produced by the model. Results: A total of 84.33% (6,621 childhood deaths had completed VA data during the study period. Children aged 1–4 years constituted 48.53% of all cases, and 42.50% were from infants. A single cause of death was assigned to 89.18% (5,940 of cases, 8.35% (556 of cases were assigned two causes, and 2.10% (140 were assigned ‘indeterminate’ as cause of death by the InterVA-4 model. Overall, malaria (28.20% was the leading cause of death, followed by acute respiratory infection including pneumonia (25.10%, in under-5 children over the study period. But in the first 5 years of the study period, acute respiratory infection including pneumonia was the main cause of death, followed by malaria. Similar trends were also reported in infants (29 days–11 months and

    We examined the prevalence of body dysmorphic disorder (BDD) in a Veterans Affairs (VA) primary care behavioral health clinic. Of 100 Veterans, 11% (95% CI = 6.3-18.6%) had current BDD and 12% (95% CI = 7.0-19.8%) had lifetime BDD. However, only 8.3% of these Veterans had been diagnosed with BDD. BDD was significantly associated with a substantially elevated rate of suicide attempts, major depression, and obsessive-compulsive disorder. This severe disorder appears to be underdiagnosed in VA settings. PMID:25935375

    Because of its weakly acidic nature (pKa of 4.5), indomethacin presents an aqueous solubility that significantly increases when changing from acidic to neutral/alkaline pH (1.5 μg/mL at pH 1.2 and 105.2 μg/mL at pH 7.4). We have therefore investigated the impact of the dissolution medium pH on the dissolution performance of indomethacin:Kollidon VA64 extrudates. The impact of the drug loading on the dissolution properties of these systems was also examined (5%, 15%, 30%, 50%, 70%, and 90% drug loading). Time-resolved Raman spectroscopy along with in-line UV-vis spectrophotometry was employed to directly relate changes in dissolution behavior to physicochemical changes that occur to the extrudate during the test. The dissolution tests were performed in pH 2 HCl (to mimic the stomach conditions), and this was then switched during the experiment to pH 6.8 phosphate buffer (to simulate the poststomach conditions). The rotating disc dissolution rate test was also used to simultaneously measure the dissolution rate of both the drug and the polymer. We found that in pH 2 HCl buffer, for the 15% or higher drug-loaded extrudates, Kollidon VA64 preferentially dissolves from the exterior of the compact leaving an amorphous drug-rich hydrophobic shell, which, similarly to an enteric coating, inhibits the drug release. The in situ formation of an enteric coating has been previously hypothesized, and this has been the first time that is directly observed in a pH-variable dissolution test. The dissolution medium switch to pH 6.8 phosphate buffer, due to the large increase of the aqueous solubility of indomethacin at this pH, leads to rapid dissolution of the material forming the coating and therefore total drug release. In contrast, the 5% extrudate is fully hydrated and quickly dissolves at low pH pointing to a dissolution performance dependent on highly water-soluble Kollidon VA64. PMID:26845251

    2016-08-01

    Addressing vaginal laxity, atrophic vaginitis, stress urinary incontinence (SUI), and different manifestations of sexual dysfunction has always been problematic due to women's traditional difficulty discussing these issues with doctors as well as the societal attitude of resignation toward these conditions. The recent rise of non-invasive feminine rejuvenation using energy-based modalities to vaginal tissue has its origins in aesthetic medicine. Transcutaneous temperature-controlled radiofrequency therapy at the vulvovaginal region has shown promising results in giving a more youthful appearing vulva, restoration of vaginal elasticity and 'tightness', considerable improvement in SUI, reduction in overactive bladder symptoms, and reduction in sexual dysfunction. It is also emerging as the non-invasive treatment modality for mild to moderate SUI. It seems that the time has come, when women shall ever be grateful to their gynecologist for management of SUI with ThermiVa without an incision. PMID:27382227

    2006-06-01

    Full Text Available The purpose of this paper is to analyze backtesting methodologies of VaR, focusing on aspects as suitability to volatile markets and limited data set. We verify, from regulatory standpoint, tests to complement the Basel traffic light results, using simulated and real data. The results indicate that tests based on failures proportion are not adequate for small samples even fro 1,000 observations. The Basel criterion is conservative and has low power, which does not invalidate its application, as the criterion is only one of the procedures adopted in internal model validation process. Thus, it is suggested using tests that capture the shape of returns distribution, as the Kuiper test, in addition to the Basel criterion.

    Automobile insurance is one of the emerging general insurance's product in Indonesia. Fluctuation in total premium revenues and total claim expenses leads to a risk that insurance company can not be able to pay consumer's claims, thus reinsurance is needeed. Reinsurance is a risk transfer mechanism from the insurance company to another company called reinsurer, one of the reinsurance type is Stoploss. Because reinsurer charges premium to the insurance company, it is important to determine the retention or the total claims to be retain solely by the insurance company. Thus, retention is determined using Value at Risk (VaR) which minimize the total risk of the insurance company in the presence of Stoploss reinsurance. Retention depends only on the distribution of total claims and reinsurance loading factor. We use the compound Poisson distribution and the Log-Normal Distribution to illustrate the retention value in a collective risk model.

    Focused Acceptance & Commitment Therapy (FACT) is a brief intervention based on traditional Acceptance and Commitment Therapy (ACT). Although there is a growing body of research on the efficacy of ACT for a variety of populations and disorders, there is little research to date on the use of FACT in group settings. This project is 1 of the first of its kind, as it examines data on psychological flexibility, health and mental health status, and symptom reduction from a 4-week FACT group. Participants in this study were 51 patients who attended this group as part of routine clinical care in a VA integrated primary care and mental health setting. They completed pre- and posttreatment measures of well-being, depression, anxiety, stress, psychological flexibility, and perceptions of physical and mental health functioning. Pre- to posttreatment analyses of variance demonstrated large effects for quality of life, F(1, 51) = 21.29, p scale), F(1, 51) = 9.67, p = .003, η2 = 0.11, and small effects for perceptions of perceived stress, F(1, 51) = 4.08, p = .04, η2 = 0.03, and physical health functioning (PCS scale), F(1, 51) = 6.60, p = .01, η2 = 0.08. There was a statistical trend for reductions in anxiety, F(1, 51) = 3.29, p = .07, η2 = 0.01, and a nonsignificant effect for psychological flexibility, F(1, 51) = 2.05, p = .16, η2 = 0.04. These data provide initial support for the implementation of a group-based FACT protocol within a VA primary care setting and help to lay a foundation for further, more controlled studies on Group FACT in future research.

    Full Text Available En este trabajo se estudió el desempeño de un estimador del VaR de portafolios de acciones basado en el cálculo de los coeficientes beta de las acciones que lo conforman, conocido como el VaR factorial. Para ello se proyectaron tales betas recursivamente, por medio del filtro de Kalman y modelando el término, que depende de la volatilidad de los rendimientos del mercado, de acuerdo con modelos condicionalmente heterocedásticos del tipo GARCH, EGARCH y GJR. A partir de simulaciones basadas en un modelo de baja oscilación para las betas, se compararon (con la metodología media-varianza de RiskMetrics los resultados de estos modelos con el VaR calculado y se introdujeron dos pruebas de hipótesis para realizar tal comparación. La conclusión es que tanto el estimador propuesto como el de RiskMetrics pronostican correctamente el número de casos en los cuales los rendimientos extremos negativos de un portafolio superan el margen del VaR. No obstante, el estimador propuesto calcula de forma más precisa que el método de RiskMetrics el valor mediante el cual se supera tal margen.This paper studies the performance of an estimator used to calculate VaR for a stock portfolio using stock Beta coefficients. Such coefficients are recursively projected using Kalman's filter and modelling the market-volatility restrained term according to conditionally heteroscedastic GARCH, EGARCH and GJR models. A low Beta oscillation model is used to carry out diverse simulations and the results are compared with RiskMetrics mean-variance. Two hypothesis tests were introduced. We conclude that the new estimator is as effective as the one used by RiskMetrics to foresee those cases in which extremely negative yields overflow the VaR margin. However, our estimator is a better predictor of the excess amount on VaR margin than the one used by RiskMetrics.

  2. Contribution of soil-32P, fertilizer-32P and VA mycorrhizal fungi to phosphorus nutrition of corn plant

    International Nuclear Information System (INIS)

    32P labelled fertilizer and five synthetic phosphates (dicalcium phosphate, octocalcium phosphate, iron phosphate, aluminium phosphate and apatite), which were used to simulate inorganic phosphates such as Ca2-P, Ca8-P, FeP, Al-P and Ca10-P in calcareous soil, were applied to corn plants inoculating with and without vesicular-arbuscular (VA) mycorrhizal fungi in a calcareous soil. The results showed that VA mycorrhizal fungi and dicalcium phosphate, octocalcium phosphate, iron phosphate, aluminium phosphate promoted growth and increased phosphorus content of corn plant. The four synthetic phosphates except apatite had higher contributions to corn plant growth than VA mycorrhizal fungi. Contributions of fertilizer-P, soil-P and synthetic phosphates to phosphorus nutrition of corn plant were in order of synthetic phosphates (except apatite) > soil- P > fertilizer-P. Inoculating with VA mycorrhizal fungi increased the contribution of soil-P and decreased the contribution of synthetic phosphates, but did not affect the contribution of fertilizer-P

Here, we describe an update that now includes all possible glycerophosphoinositols, glycerophosphoinositol monophosphates, glycerophosphoinositol bisphosphates, and glycerophosphoinositol trisphosphates. This update expands the total number of lipid species represented in the VaLID v2.0.0 database to 1,473,168 phospholipids. Each phospholipid can be generated in skeletal representation. A subset of species curated by the Canadian Institutes of Health Research Training Program in Neurodegenerative Lipidomics (CTPNL team is provided as an array of high-resolution structures. VaLID is freely available and responds to all users through the CTPNL resources web site.

    Four children in three unrelated families (one consanguineous) presented with lethargy, hyperlactatemia, and hyperammonemia of unexplained origin during the neonatal period and early childhood. We identified and validated three different CA5A alterations, including a homozygous missense mutation (c.697T>C) in two siblings, a homozygous splice site mutation (c.555G>A) leading to skipping of exon 4, and a homozygous 4 kb deletion of exon 6. The deleterious nature of the homozygous mutation c.697T>C (p.Ser233Pro) was demonstrated by reduced enzymatic activity and increased temperature sensitivity. Carbonic anhydrase VA (CA-VA) was absent in liver in the child with the homozygous exon 6 deletion. The metabolite profiles in the affected individuals fit CA-VA deficiency, showing evidence of impaired provision of bicarbonate to the four enzymes that participate in key pathways in intermediary metabolism: carbamoylphosphate synthetase 1 (urea cycle), pyruvate carboxylase (anaplerosis, gluconeogenesis), propionyl-CoA carboxylase, and 3-methylcrotonyl-CoA carboxylase (branched chain amino acids catabolism). In the three children who were administered carglumic acid, hyperammonemia resolved. CA-VA deficiency should therefore be added to urea cycle defects, organic acidurias, and pyruvate carboxylase deficiency as a treatable condition in the differential diagnosis of hyperammonemia in the neonate and young child.

  12. Morphological research on radio loud AGN 4C39.25 using KaVA observations

    4C39.25 (0923+392) is a distant radio loud AGN placed at redshift 0.695. Its kilo-parsec scale jet observed by VLBA(Kollgaard et al. 1990) and parsec scale jet observed by VLBA(Kellermann et al. 1998) are misaligned. This might indicate episodic-jet activity which recently turned on. This object currently shows two stationary compact parsec-scale components:a bright jet component on the east and less luminous core on the west. Also, it is known that there have been superluminal jet components which are flowing from the core toward east, and then merging with the bright jet component (Marscher et al. 1991, Alberdi et al. 2000, Lister et al. 2013). Including the detection of broad emission lines(SDSS), its viewing angle was concluded to be small. However, the jet component being more luminous than the core is abnormal for a source with a small viewing angle. Furthermore, it has young radio galaxy-like properties such as non-variation in total flux(Alberdi et al. 1997, 2000, MOJAVE database) and a high frequency peak in the spectral energy distribution(Orienti et al 2007). In this case, it is more reliable to think that viewing angle of 4C39.25 is large. Korean VLBI Network (KVN) and VLBI Exploration of Radio Astronomy (VERA) Array (KaVA) is a cooperated VLBI system of Korea and Japan which provides high-frequency (23GHz and 43GHz) and high spatial resolution(1.2mas and 0.6mas). Their advantages of multi-wavelength and relatively high S/N ratio relative to its number of baseline allow us to discover the central region and dim structures of 4C39.25. We present results of several epochs observed during 2013 to 2014, focusing on morphological changes of 4C39.25 using KaVA images. According to these results, we were able to find a recently emitted counter-jet component for images of first 6 epochs. Also the counter-jet component propagates along a curved trajectory, and it shows an extreme superluminal motion. This might indicate a necessity of relatively large viewing

    Full Text Available Biochars can be used as soil amendments for improving soil properties and crop yield. The objective of this research was to study the plant growth, yield, yield components, and seed quality, including nutrients and heavy metals (Pb, Cd, and Hg, in the soybean plant (Glycine max L. Merr. and soil. The experiment was conducted from September 2010 to January 2011 in a greenhouse located in the Dan Khun Thot District, Nakhon Ratchasima Province, Thailand. The research comprised six treatments with four replicates in a completely randomized design. Quail litter biochar (QLB at rates of 0, 24.6, 49.2, 73.8, 98.4 and 123 g per pot mixture were provided to soybean cv. Chiang Mai 60. The results showed that QLB could be used as a soil fertility improvement and amendment for soybean production with an optimum rate of 98.4 g per pot mixture, which gave the best performance in terms of the number of nodes, height, DM accumulation, total yield, and seed quality. After the experiment, the nutrient contents in the soil increased as the QLB content increased, but the heavy metal residues in the leaves and seeds did not change. However, QLB at levels higher than 98.4 g per pot mixture is not advisable because QLB is alkaline in nature, which may affect soil pH.El biocarbón puede usarse como enmienda para mejorar las propiedades del suelo y el rendimiento del cultivo.

    This study was designed to compare the quality of liquid-stored buffalo bull spermatozoa in soya lecithin based extender Bioxcell(®) (BIOX), milk (MILK), tris-citric egg yolk (TEY) and egg yolk-citrate (EYC) extender at 5°C. Semen was collected from five Nili-Ravi buffalo (Bubalus bubalis) bulls of 6-7 years of age with artificial vagina over a period of 3 weeks (two consecutive ejaculates once in a week). Semen ejaculates having more than 60% motility were pooled, split into four aliquots, diluted (37°C; 10 × 10(6) motile spermatozoa/ml), cooled from 37 to 5°C in 2 h (0.275°C/min) and stored for 5 days. Sperm motility, viability, plasma membrane integrity (PMI) and normal acrosomal ridge were studied at first, third and fifth day of storage. Higher values of progressive sperm motility (%), sperm viability (%), sperm PMI (%) and normal apical ridge (%) were observed in BIOX, MILK and TEY extenders at first, third and fifth day of storage than EYC extender. Progressive sperm motility, sperm viability and sperm PMI in BIOX(®) extender were not different from MILK and TEY extenders at 1st and third day storage period. However, at fifth day of storage, the values for these parameters remained significantly higher (p<0.05) in BIOX(®) compared with MILK, TEY and EYC extenders. At fifth day of storage, the semen quality parameters for Bioxcell(®) were comparable to those with MILK and TEY extenders at third day of storage. In conclusion, motility, viability and PMI of buffalo bull spermatozoa remained similar in Bioxcell(®) , milk and TEY extender at first and third days of storage at 5°C. Yet, the values for the aforementioned parameters in Bioxcell(®) were higher compared with milk, TEY and EYC extender at fifth day of storage at 5°C. PMID:20070582

  19. Role of the Acidic Hirudin-like COOH-Terminal Amino Acid Region of Factor Va Heavy Chain in the Enhanced Function of Prothrombinase†‡

    Science.gov (United States)

    2008-01-01

    Prothrombinase activates prothrombin through initial cleavage at Arg320 followed by cleavage at Arg271. This pathway is characterized by the generation of an enzymatically active, transient intermediate, meizothrombin, that has increased chromogenic substrate activity but poor clotting activity. The heavy chain of factor Va contains an acidic region at the COOH terminus (residues 680−709). We have shown that a pentapeptide from this region (DYDYQ) inhibits prothrombin activation by prothrombinase by inhibiting meizothrombin generation. To ascertain the function of these regions, we have created a mutant recombinant factor V molecule that is missing the last 30 amino acids from the heavy chain (factor VΔ680−709) and a mutant molecule with the 695DYDY698 → AAAA substitutions (factor V4A). The clotting activities of both recombinant mutant factor Va molecules were impaired compared to the clotting activity of wild-type factor Va (factor VaWt). Using an assay employing purified reagents, we found that prothrombinase assembled with factor VaΔ680−709 displayed an ∼39% increase in kcat, while prothrombinase assembled with factor Va4A exhibited an ∼20% increase in kcat for the activation of prothrombin as compared to prothrombinase assembled with factor VaWt. Gel electrophoresis analyzing prothrombin activation by prothrombinase assembled with the mutant molecules revealed a delay in prothrombin activation with persistence of meizothrombin. Our data demonstrate that the COOH-terminal region of factor Va heavy chain is indeed crucial for coordinated prothrombin activation by prothrombinase because it regulates meizothrombin cleavage at Arg271 and suggest that this portion of factor Va is partially responsible for the enhanced procoagulant function of prothrombinase.

    2000-01-01

    For over 25 years, personal assistant robots for severely disabled individuals have been in development. More recently, using robots to deliver rehabilitation therapy has been proposed. This paper summarizes the development and clinical testing of three mechatronic systems for post-stroke therapy conducted at the VA Palo Alto in collaboration with Stanford University. We describe the philosophy and experiences that guided their evolution. Unique to the Palo Alto approach is provision for bimanual, mirror-image, patient-controlled therapeutic exercise. Proof-of-concept was established with a 2-degree-of-freedom (DOF) elbow/forearm manipulator. Tests of a second-generation therapy robot producing planar forearm movements in 19 hemiplegic and control subjects confirmed the validity and reliability of interaction forces during mechanically assisted upper-limb movements. Clinical trials comparing 3-D robot-assisted therapy to traditional therapy in 21 chronic stroke subjects showed significant improvement in the Fugl-Meyer (FM) measure of motor recovery in the robot group, which exceeded improvements in the control group.
