    A population density of Emerita asiatica in relation to sand organic carbon in the Nemmeli beach, East coast, Kanchipuram District of Tamil Nadu was studied. Specimens were collected once in a fortnight from April 2017 to March 2018 by hand picking method in the intertidal region of Nemmeli beach. The total sand organic carbon level was recorded once in a fortnight. The population presented a smaller incidence of males in relation to females (48.66:51.34); however, in May 2017 an inverse pattern occurred (73:27). Ovigerous females were present in all samples with greater frequencies in October and November 2017 whereas, the highest juveniles were present in May and September 2017. The variation noted in a population of Emerita asiatica showed there is a relationship to sand organic carbon fluctuations; it can be determined that the sand organic carbon fluctuations have an influence on the population density of this species in Nemmeli beach. Hence, the rather stable sand organic carbon throughout the year and moderate changes in the sand may well be conducive to population biology of Emerita asiatica

    188-196The present work focused on Phytochemical screening, characterization, anticancer activity and antibiological activity of ethyl acetate extract of Melochia corchorifolia leaves followed by molecular docking studies have been carried out. The plant leaves have been collected, weighed, and extracted with the soxhlet apparatus by using ethyl acetate solvent and then extracted are subjected to phytochemical screening.  Antibiological activity of plant leaves ethyl acetate extract has been tested against six bacterial and two fungal strains using agar well diffusion methodology. The characterization of phytoconstituents compounds has been carried out using various spectroscopy method such as GC-MS (Gas chromatography Mass spectroscopy), UV-visible and Fourier-transform infrared. Auto dock tool (4.2.0) is used for molecular docking studies. The phytochemical analysis of Melochia corchorifolia ethyl acetate leaves, reveals the existence of carbohydrates, glycosides, triterpenes flavonoids and alkaloids. Antimicrobial activity is effective against gram-positive bacterial strains namely Staphylococcus aureus (17 mm), Bacillus subtilis (16 mm), the gram-negative bacterial strains namely Salmonella typhi (15 mm) and E. coli (14 mm). Moreover, the extract is also found to be effective against Aspergillus Niger (18 mm) fungal species. The GC-MS and FT-IR analysis show bioactive compounds and their functional groups. UV-VIS analysis results reveal that the presence of phytoconstituents derivatives in the range between 206-350 nm. The cytotoxicity activity for the MCF-7 cell line shows that the drug efficacy IC50 value is 148.836 (μg/mL). Further, the predicted bioactive compounds are docked with the cancer estrogen protein receptor (PDB ID: 3s7s) with ligand martidin-15 one shows the highest binding affinity. The study reveals the potential of Melochia corchorifolia leaves ethyl acetate extract showed antibiological and anticancer activity

    Early life child micronutrient status, maternal reasoning, and a nurturing household environment have persistent influences on child cognitive development at age 5 years: Results from MAL-ED

    Background: Child cognitive development is influenced by early-life insults and protective factors. To what extent these factors have a long-term legacy on child development and hence fulfillment of cognitive potential is unknown. Objective: The aim of this study was to examine the relation between early-life factors (birth to 2 y) and cognitive development at 5 y. Methods: Observational follow-up visits were made of children at 5 y, previously enrolled in the community-based MAL-ED longitudinal cohort. The burden of enteropathogens, prevalence of illness, complementary diet intake, micronutrient status, and household and maternal factors from birth to 2 y were extensively measured and their relation with the Wechsler Preschool Primary Scales of Intelligence at 5 y was examined through use of linear regression. Results: Cognitive T-scores from 813 of 1198 (68%) children were examined and 5 variables had significant associations in multivariable models: mean child plasma transferrin receptor concentration (β: −1.81, 95% CI: −2.75, −0.86), number of years of maternal education (β: 0.27, 95% CI: 0.08, 0.45), maternal cognitive reasoning score (β: 0.09, 95% CI: 0.03, 0.15), household assets score (β: 0.64, 95% CI: 0.24, 1.04), and HOME child cleanliness factor (β: 0.60, 95% CI: 0.05, 1.15). In multivariable models, the mean rate of enteropathogen detections, burden of illness, and complementary food intakes between birth and 2 y were not significantly related to 5-y cognition. Conclusions: A nurturing home context in terms of a healthy/clean environment and household wealth, provision of adequate micronutrients, maternal education, and cognitive reasoning have a strong and persistent influence on child cognitive development. Efforts addressing aspects of poverty around micronutrient status, nurturing caregiving, and enabling home environments are likely to have lasting positive impacts on child cognitive development.publishedVersio
