The present study was to investigate the effect of ferulic acid and resveratrol on alloxan-induced diabetic mice, through analysis of basic biochemical parameters, enzymic as well as non-enzymic activities, lipid peroxidation and immunohistochemical studies. Alloxan was administered as a single dose (75 mg/kg body weight) to induce diabetes in mice. A dose(More)
In the present study, we have synthesized silver nanoparticles by a simple and eco-friendly method using unripe fruits of Solanum trilobatum. The aqueous silver ions when exposed to unripe fruits extract were reduced and stabilized over long time resulting in biosynthesis of surface functionalized silver nanoparticles. The bio-reduced silver nanoparticles(More)
Cancer is a multistep process that typically occurrs over an extended period of time, beginning with initiation followed by promotion and progression. Colon cancer is the leading cause of morbidity and mortality worldwide. For a variety of reasons, patients prefer naturally occurring dietary substances over synthetic agents to prevent cancer. Luteolin, a(More)
This study was performed to detect and characterise the possible occurrence of natural and inducible lectins in human serum by hemagglutination method, wherein, the serum was treated using exogenous elicitors, namely, proteases and detergents. Natural and inducible lectins were detected and characterised in human serum. Untreated serum agglutinated buffalo(More)
Natural and induced phenoloxidase activities were detected in human serum using nine different phenolic substrates, namely, tyrosine, tyramine, L-DOPA, DL-DOPA, dopamine, catechol, hydroquinone, protocatechuic acid and pyrogallol. Phenoloxidase activity was induced anew in serum using exogenous elicitors, such as proteases or detergents. Among the proteases(More)
Metallic nanoparticles are major concern, particularly silver nanoparticles (AgNPs) are used in various applications. In the present investigation, we report a novel strategy with biological approach for synthesis of AgNPs using sodium para-hydroxybenzoate tetrahydrate (SPHT) isolated from Vitex negundo leaves. The synthesized SPHT-AgNPs were characterized(More)
This review discusses the relationship between oxidative stress and cataract formation, molecular mechanism of curcumin action and potential benefits of treatment with the antioxidant curcumin. The first section deals with curcumin and endogenous antioxidants. The second section focuses on the action of curcumin on lipid peroxidation. Calcium homeostasis(More)
The emergence and spread of pathogens harboring extended spectrum beta-lactamase (ESBL) like carbapenem resistant Gram negative bacteria are the major emerging threat to public health. Of particular concern Klebsiella pneumoniae carbapenamase- producing strains have been recorded worldwide. Catheter associated urinary tract infections (CAUTI) caused by K.(More)
Human serum albumin (HSA) was identified as the component involved in generation of neo-lectin molecules with both lectin and phenoloxidase activities. Pronase treated HSA was able to agglutinate hen RBC and oxidize hydroquinone. Sodium dodecyl sulphate (SDS) treated HSA agglutinated both hen and sheep RBC as well as oxidized dopamine. The hemagglutinating(More)
A new lectin was purified to electrophoretic homogeneity from pronase treated human serum by a single-step of affinity chromatography on concanavalin A-Sepharose 4B. The isolated lectin agglutinated five types of vertebrate RBC, with highest titer against hen RBC. This activity was independent of divalent cations, insensitive to EDTA and specific to(More)
