A time course study on the sublethal toxicity of CuSO4 on tissue carbohydrate metabolites level and their phosphatases activity in Achatina fulica revealed differential response. The levels of total carbohydrates and glycogen in the body mass muscle, foot muscle and hemolymph revealed their involvement in the endogenous derivation of energy during stress.(More)
—Wireless sensor networks (WSNs) are used for the monitoring of physical and environmental phenomena, and applicable in a range of different domains (e.g., health care, military, critical infrastructure). When using WSNs in a variety of real-world applications, security is a vital problem that should be considered by developers. As the development of(More)
—Wireless sensor networks (WSNs) are used in a range of critical domains (e.g., health care, military, critical infrastructure) where it is necessary that the nodes be reprogrammed with a new or modified code image without removing them from the deployment area. Various protocols have been developed for the dissemination of code images between sensors in(More)
Collagenase (matrix metalloproteinase-1, EC:3.4.24.7) was isolated from the hepatopancreas of Achatina fulica and characterized for its enzymatic activity and immunological properties. Procollagenase was isolated using ammonium sulphate precipitation and gel filtration, followed by purification by reverse-phase high performance liquid chromatography in the(More)
The production of a lipopeptide surfactant from the sponge-associated eubacteria Bacillus licheniformis NIOT-AMKV06 from the Andaman and Nicobar Islands was investigated. The highest production was attained with glucose and yeast extracts as the carbon and nitrogen sources (1.789 mg mL(-1)), respectively. The surfactant was highly stable over a pH range of(More)
9-O-Acetyl neuraminic acid specific lectin (AchatininH) was isolated from the hemolymph of the land snail Achatina fulica by affinity chromatography on sheep submaxillary mucin (SSM) coupled cyanogen bromide activated Sepharose 4B. The molecular weight of the native protein was 2.42 kDa. UV-Vis absorption, fluorescence and circular dichroism spectroscopic(More)
The interaction of the beta-amyloid peptide (Abeta) with neuronal membranes could play a key role in the pathogenesis of Alzheimer's disease. Recent studies have focused on the interactions of Abeta oligomers to explain the neuronal toxicity accompanying Alzheimer's disease. In our study, we have investigated the role of lipid interactions with soluble(More)
In Rana tigrina, blood levels of total carbohydrates, lactic acid and pyruvic acid were determined in relation to allometric growth in both sexes. The blood carbohydrates content increased in relation to growth and maturity of gonads. Treatment by phosalone resulted in the accumulation of lactic acid in blood suggesting that this organophosphate compound(More)
The giant freshwater prawn Macrobrachium rosenbergii was injected with an inoculum containing LD, 96 hr dose of 10' Pseudomonas aeruginosa (MTCC 1688) to determine the histopathological effects in vivo. The comparison of tissues of both the control and the bacterial endotoxin treated prawns after 96 hr revealed significant degenerative changes in treated(More)
