The polysaccharide-fucoidan was extracted from brown seaweed Sargassum wightii and characterized through FT-IR and (13)C &(1)H NMR analysis. The extracted fucoidan was supplemented with pellet diets at three different concentrations (0.1, 0.2 and 0.3%). The fucoidan supplemented diets were fed to Penaeus monodon for 45 days, then challenged with WSSV and(More)
Memory in the nervous system is essentially a network effect, resulting from activity-dependent synaptic modification in a network of neurons. Like the nervous system, the heart is a network of cardiac cells electrically coupled by gap junctions. The heart too has memory, termed cardiac memory, whereby the effect of an external electrical activation(More)
BACKGROUND & OBJECTIVES Derivatives of isatin are known to have cytotoxicity against human carcinoma cell lines. This compound therefore, has a potential to be used as a chemotherapeutic agent against cancer. This study was done to investigate the antioxidant and anticancer activities of isatin, extracted from flower of a folklore medicinal plant Couroupita(More)
In this study, we demonstrate a simple, full field displacement characterization technique based on digital image correlation (DIC). We develop a robust correlation measure implemented in a code and use it to characterize materials at high spatial and displacement resolution. We describe the methods implemented in the DIC code and compare against those(More)
A probiotic yeast, Saccharomyces cerevisiae was incorporated in basal diet prepared with fish meal, soybean meal, groundnut oil cake, corn flour, tapioca flour, egg albumin, cod liver oil and vitamin Bcomplex, at four different concentrations (10g, 20g, 30g and 40g kg) and fed to Macrobrachium rosenbergii post larvae (PL) for 90 days. The effect of this(More)
Lipopolysaccharide (LPS) is the main surface constituent of Gram-negative bacteria. Lipid A, the hydrophobic moiety, outer monolayer of the outer cell membrane forms the major component of LPS. Immunogenic Lipid A is recognized by the innate immune system through the TLR 4/MD-2 complex. Pseudomonas aeruginosa PAO1, a Gram-negative bacterium is known to(More)
To assess the growth-promoting potential of three medicinal herbs, Alteranthera sessilis, Eclipta alba and Cissus quadrangularis, a 90-day feeding trial was conducted on Macrobrachium rosenbergii post-larvae (PL) fed with these herb-incorporated feeds. The growth parameters (survival rate, weight gain, specific growth rate and protein efficiency ratio) were(More)
Soil is a complex and dynamic biological system. Agroforestry systems are considered to be an alternative land use option to help and prevent soil degradation, improve soil fertility, microbial diversity, and organic matter status. An increasing interest has emerged with respect to the importance of microbial diversity in soil habitats. The present study(More)
2,4-Dinitrophenol (2,4-DNP), 2,4-dinitroaniline (2,4-DNA), 2,6-dinitroaniline (2,6-DNA) and 2,6-dinitrobenzoic acid (2,6-DNB) has appeared for the UV absorption bands in different wavelength region below 400 nm, a combination of these dinitro aromatic compounds gave the broad absorption spectra within the UV region. The absorption intensities have been(More)
