Captive breeding and embryonic development of honey gourami, Colisa sota (Ham.-Buch.)

Honey Gourami, Colisa sota, has high ornamental as well as food value. The natural resources of this species are gradually declining, due to destruction of its habitat, over fishing for aquarium trade and human consumption. The fish was bred in captivity under controlled environment. It laid about 200-400 eggs in bubble nest built by the male. Hatching started within 28-30hrs. after egg laying. The hatchlings became free swimming by 3rd to 4th day of hatching. The male showed territoriality and parental care by guarding the eggs and hatchlings. The larval survival was 30-35%. The breeding behavior, embryonic and post embryonic development of the fish were studied

Anemia prevalence in women of reproductive age in low- and middle-income countries between 2000 and 2018

Anemia is a globally widespread condition in women and is associated with reduced economic productivity and increased mortality worldwide. Here we map annual 2000–2018 geospatial estimates of anemia prevalence in women of reproductive age (15–49 years) across 82 low- and middle-income countries (LMICs), stratify anemia by severity and aggregate results to policy-relevant administrative and national levels. Additionally, we provide subnational disparity analyses to provide a comprehensive overview of anemia prevalence inequalities within these countries and predict progress toward the World Health Organization’s Global Nutrition Target (WHO GNT) to reduce anemia by half by 2030. Our results demonstrate widespread moderate improvements in overall anemia prevalence but identify only three LMICs with a high probability of achieving the WHO GNT by 2030 at a national scale, and no LMIC is expected to achieve the target in all their subnational administrative units. Our maps show where large within-country disparities occur, as well as areas likely to fall short of the WHO GNT, offering precision public health tools so that adequate resource allocation and subsequent interventions can be targeted to the most vulnerable populations.Peer reviewe

Search for H→γγ produced in association with top quarks and constraints on the Yukawa coupling between the top quark and the Higgs boson using data taken at 7 TeV and 8 TeV with the ATLAS detector

A search is performed for Higgs bosons produced in association with top quarks using the diphoton decay mode of the Higgs boson. Selection requirements are optimized separately for leptonic and fully hadronic final states from the top quark decays. The dataset used corresponds to an integrated luminosity of 4.5 fb−14.5 fb−1 of proton–proton collisions at a center-of-mass energy of 7 TeV and 20.3 fb−1 at 8 TeV recorded by the ATLAS detector at the CERN Large Hadron Collider. No significant excess over the background prediction is observed and upper limits are set on the tt¯H production cross section. The observed exclusion upper limit at 95% confidence level is 6.7 times the predicted Standard Model cross section value. In addition, limits are set on the strength of the Yukawa coupling between the top quark and the Higgs boson, taking into account the dependence of the tt¯H and tH cross sections as well as the H→γγ branching fraction on the Yukawa coupling. Lower and upper limits at 95% confidence level are set at −1.3 and +8.0 times the Yukawa coupling strength in the Standard Model

Określenie całkowitej zawartości fenoli i flawonoidów oraz potencjału antyoksydacyjnego Apium leptophyllum Pers.

At present, major causes of diseases is oxidative stress affecting both metabolic and physiological functions of the body. That is why there is a great need for investigation of nutritious food supplements for counteracting these oxidative stresses. Therefore, the aim of study was to evaluate the therapeutic potential of Apium leptophyllum Pers. fruits by estimating total phenolic as well as flavonoidal contents and antioxidant values. The collected fruits were extracted separately using different solvents like methanol, ethanol and water. Total phenolic and flavonoid contents were measured from the respective extracts and correlated with their antioxidant values. The antioxidant properties of various fruit extracts (12.5, 25, 50, 100 and 150 μg/ml) were evaluated by DPPH, hydroxyl, nitric oxide and superoxide scavenging assay and compared with ascorbic acid as a standard. All the extracts of A. leptophyllum were found to be dose dependent inhibition against these free radicals. Among all these extracts, the methanolic one was found better in the scavenging activity and followed dose-dependent manner against DPPH, hydroxyl radical, nitric oxide, superoxide anions with minimum IC50 values of 97.9, 89.02, 135.37, 127.73 μg/ml, respectively, and also observed more significant (p<0.01) as compared with standard. Furthermore, total phenolic and flavonoidal contents were found highest in methanolic extract. The results obtained in this study clearly indicate that the methanolic extract of A. leptophyllum may be used as a new potential source of natural nutritional supplement in food or pharmaceutical industries due to rich source of phenolic, flavonoidal contents as well as antioxidant property.Obecnie główną przyczyną chorób jest stres oksydacyjny wpływający zarówno na metabolizm, jak i funkcje fizjologiczne organizmu. Dlatego istnieje duża potrzeba poszukiwania produktów uzupełniających dietę, które przeciwdziałają stresowi oksydacyjnemu. Celem niniejszej pracy było określenie potencjału terapeutycznego owoców Apium leptophyllum Pers. poprzez określenie całkowitej zawartości fenoli i flawonoidów oraz ich aktywności antyoksydacyjnej. Nasiona ekstrahowano oddzielnie, używając różnych rozpuszczalników, takich jak metanol, etanol i woda. Zmierzono całkowitą zawartość fenoli i flawonoidów w poszczególnych wyciągach i skorelowano ją z ich aktywnością antyoksydacyjną. Właściwości antyoksydacyjne różnych wyciągów z owoców (w stężeniach 12,5, 25, 50, 100 i 150 μg/ml) zmierzono za pomocą metod przy użyciu DPPH, rodników hydroksylowych, tlenku azotu, nadtlenku i porównano z właściwościami kwasu askorbowego. Stwierdzono, że działanie inhibicyjne wszystkich wyciągów z A. leptophyllum przeciwko wolnym rodnikom zależało od zastosowanej dawki. Ponadto całkowita zawartość związków fenolowych i flawonoidów była najwyższa w wyciągu metanolowym. Wyniki tych badań wyraźnie wskazują, że wyciąg metanolowy z A. leptophyllum może być używany jako potencjalne nowe źródło naturalnych suplementów diety dla przemysłu spożywczego lub farmaceutycznego dzięki wysokiej zawartości fenoli, flawonoidów i właściwościom antyoksydacyjnym

Genotype-environment interaction and stability analysis of four fine rice varieties

Genotype-environment interactions through different stability parameters and performance traits of four fine rice genotypes were studied. The traits were; days to 50% flowering, days to maturity, plant height (cm), number of effective tillers per hill, panicle length (cm), number of fertile grains per panicle, number of sterile grains per panicle and yield (t/ha) in four fine rice genotypes across nine environments along with experimental farm of Genetics and Plant Breeding department, Bangladesh Agricultural University (BAU) Mymensingh. Significant differences were observed for genotypes, environments and genotypes–environment interaction. Stability analysis after Eberhat and Russell’s model suggested that the genotypes used in study were more or less responsive to environmental changes. Most of the genotypes performed better in Comilla. BAU125 was found stable for effective tillers per hill and comparatively less sensitive to other genotypes in panicle length and number of sterile grains per panicle. BR5 was stable for days to maturity and plant height whereas Kalizira performed better than other genotypes for fertile grains per panicle. In general, only the genotype BAU125 was found stable for effective tillers per hill, panicle length and lowest number of sterile grains per panicle

Not AvailableUnder soybean-wheat system the influence of 4-year continuous cropping with different fertilizer and organic manure inputs on the transformation of different N fractions, mineralizable N, total N, and organic C in both surface and subsurface soils was investigated in a Vertisol. Repeated applications of fertilizer N alone, N with FYM or poultry manure or urban compost, FYM alone led to a significant increase in organic C, total N, hydrolysable N (i.e., amino acid N, hydrolyzable NH4-N, hexose amine N) and nonhydrolysable N in both surface and subsurface soils as compared to initial status. The status of various organic N fractions was higher in surface than the subsurface soils. On the other hand, continuous cropping without fertilization and manuring resulted in depletion of total hydrolysable N in control over the initial status by 8.5% in surface soils and 6.4% in the subsurface soils. About 3–6% of total N in surface soils and 2–5% of total N in subsurface soils got mineralized under waterlogged incubation conditions. The results clearly indicate that the subsurface soils in addition to surface soils also substantially contributed to the N requirement of the crops. The correlation studies revealed that the amino acid and hexose amine N fractions in surface soils and hydrolyzable NH4-N and amino acid N fractions in subsurface soils were better indices of soil N mineralization. This was further supported by a better correlation between amino acid N in surface and hydrolyzable NH4-N in the subsurface soils with yield of and N uptake by soybean and wheat cropsNot Availabl
