Enzyme activity and biochemical constituents of healthy and stem rot infected tissues of susceptible variety of groundnut TMV2 were evaluated. Results revealed that higher activity of Oxidative enzymes (catalase, polyphenol oxidase and peroxidase) were present in infected leaves than healthy ones. In case of Biochemical constituents, higher amount of total and Ortho-di hydric phenols and protein content was observed in infected plants as compared to healthy plants. Higher content of sugars and chlorophyll was observed in healthy plants as compared to infected plants.

A study on acute toxicity, behaviour, growth, somatic indices and oxygen consumption in Indian flying barb, Esomus danricus (Hamilton-Buchanan) on exposure to organophosphate pesticide, malathion (EC50) May 1, 2014
Acute toxicities of commercial grade malathion (EC50) on Esomus danricus were determined by static-with-renewal tests and found to be 0.026, 0.022, 0.02 and 0.017 mgl-1 respectively for 24, 48, 72 and 96 hours. During acute toxicity, the normal colour was found to fade, along with copious mucous secretions, irregular, erratic and jerky movements. Three sub […]

Assessment of genetic diversity using RAPD marker among different accessions of Salvadora oleoides of North-West India May 1, 2014
The RAPD technique has been successfully used in a variety of taxonomic and genetic diversity studies. The genetic diversity of 19 accessions of Salvadora oleoides collected from different regions of North-West India has been reported in this paper using 16 RAPD primers. 164 bands were scored corresponding to an average of 10.25 bands per primer […]

Cardioprotective effect of kolaviron (a Garcinia kola seed extract) in cholesterol-fed rats. May 1, 2014
Flavonoids – a group of polyphenolic substances are naturally present in vegetables, fruits, seeds and beverages such as tea and wine. Studies have shown that flavonoid intake is inversely correlated with mortality from coronary heart diseases and myocardial infaction. The effect of kolaviron (a flavonoid complex) extracted from garcinia kola seeds on the plasma and […]

Free radical scavenging activity of Salacia chinensis root extract in streptozotocin-induced diabetic rats May 1, 2014
This study was undertaken to evaluate the antioxidants property in the methanolic root extract of Salacia chinensis in streptozotocin (STZ) induced diabetic rats. The methanolic root extract of S. chinensis was administered orally at a dose of 250-mg/kg weight/day (28 days) to STZ-induced diabetic rats. The extract treated diabetic rats were significantly decreased the levels […]

Role of oxidative enzymes and biochemical constituents in imparting resistance to groundnut (Arachis hypogaea L.) against stem rot disease caused by Sclerotium rolfsii April 7, 2014
Enzyme activity and biochemical constituents of healthy and stem rot infected tissues of susceptible variety of groundnut TMV2 were evaluated. Results revealed that higher activity of Oxidative enzymes (catalase, polyphenol oxidase and peroxidase) were present in infected leaves than healthy ones. In case of Biochemical constituents, higher amount of total and Ortho-di hydric phenols and […]

Homology modelling and in-silico analysis of multidrug resistant protein, pmpm of Pseudomonas aeruginosa April 7, 2014
Comparative modeling remains the most dependable and routinely used method for protein structure predictions. The pmpM gene belonging to MATE family of transporters of Pseudomonas aeruginosa, an opportunistic nosocomial pathogen in humans, is a prime target sequence responsible for conferring multidrug resistance through H(+)/drug antiporter efflux pumps. Its structure elucidation is necessary to analyze its […]

Variation in oxalic acid production by groundnut isolates of Sclerotium rolfsii April 7, 2014
Thirty isolates of Sclerotium rolfsii, the causal agent of stem rot of groundnut obtained from different Rayalaseema areas of Andhra Pradesh, India were categorized into four groups, on the basis of oxalic acid production in the culture filtrate and severity of patrhogenicity on groundnut seedlings. The group four was more dominant than other groups and […]
