RESUMO
Biosynthesized nanoparticles have an incredible application in biomedicine owing to its simplicity, eco-friendly properties and low cost. The present study aims to determine the green synthesized zinc oxide nanoparticles from methanolic leaf extract of Glycosmis pentaphylla. The synthesized nanoparticles were characterized using UV-VIS Spectroscopy, Fluorescence spectrometer, FT-IR, XRD, SEM with EDAX and TEM. The confirmations of synthesized nanoparticles were characterized by peak at 351 and 410â¯nm in the UV-VIS spectrum and photoluminescence spectrum respectively. FT-IR studies revealed the functional group of the nanoparticles. The XRD data showed the crystalline nature of the nanoparticles and EDAX measurements indicated the 20.70% of highly pure zinc oxide metal. The morphological characterization of synthesized zinc oxide nanoparticles was analyzed by SEM and TEM and size of the particles were ranging from 32 to 36â¯nm. The synthesized zinc oxide nanoparticles exhibited interesting antimicrobial activity against pathogenic organisms. In addition, this is the first report on leaf mediated synthesis of zinc oxide (ZnO) nanoparticles from Glycosmis pentaphylla.

OBJECTIVES: In this paper we examine the role of mothers' nutritional status and socio-biological aspects in determining the birth weight of their most recent child. METHODS: We used data from the second Indian National Family Health Survey conducted in 1998-1999. Analysis is based on children born within 12 months prior to the survey date (N = 10,042). We used a subjective measure of the size of infant at birth as an indicator for birth weight and employed logistic regression to estimate the effect of BMI and other determinants on birth weight of children in India as a whole and for 17 states separately. RESULTS AND CONCLUSIONS: Results show that mothers' nutritional status is the most important determinant of newborn children's birth weight. Safe drinking water, use of antenatal care and iron deficient anaemia were also significant contributors to low birth weight. Mothers' BMI impact is more pervasive across India than the impact of other factors on birth weight.
