In the second experiment as reported in the previous chapter, an anti cataract activity of Captopril against oxidant stress induced cataract was investigated attributed to its antioxidant properties. The antioxidant property of Captopril is greatly influenced by the presence of thiol group in its structure which helps to interact with lens specific enzymes and proteins as well. After absorption...

The present investigation was carried out to determine the antioxidant properties in methanolic extract of leaves, stem, fruit and roots of Physalis angulata (L). The antioxidant assay was carried out using free radicals DPPH, superoxide, nitric oxide, hydrogen peroxide and hydroxyl radical. Among the extracts tested fruit and leaf extracts were found to be significant in their antioxidant prop...

We prove a positivity property for the cup product in the T -equivariant cohomology of the flag variety. This was conjectured by D. Peterson and has as a consequence a conjecture of S. Billey. The result for the flag variety follows from a more general result about algebraic varieties with an action of a solvable linear algebraic group such that the unipotent radical acts with finitely many orb...

The ethanol crude extract of stem bark of Holoptelea integrifolia Planch. traditionally used in Indian system of medicine was screened for its antioxidant activity using α-tocopherol as standard antioxidant. The free radical scavenging potential of the extract was evaluated by two different antioxidant methods; ferric thiocyanate and thiobarbituric acid method. The ethanol extract was found to ...

The present study was carried out to investigate the antioxidant potential, total flavonoid and phenolic content in extracts of aerial parts of Cordia retua (Vahl.) Masam. The samples such as ethyl acetate and ethanol extracts were tested using six in vitro models such as 2,2-diphenyl-1-picrylhydrazyl, nitric oxide radical, iron chelating, hydroxyl radical, superoxide radical scavenging activit...

We prove that the v-decomposition number dλμ(v) is an even or odd polynomial according to whether the partitions λ and μ have the same relative sign (or parity) or not. We then use this result to verify Martin’s conjecture for weight 3 blocks of symmetric group algebras — that these blocks have the property that their projective (indecomposable) modules have a common radical length 7.

Formation of inclusion complex of curcumin with β-cyclodextrin ( β-CD) has been characterized by absorption and fluorescence spectroscopy. From temperature-dependent fluorescence measurements, the thermodynamic parameters ∆H and ∆S, for the complexation were estimated. Kinetics of binding was studied by stopped flow technique, from which the binding constants for inclusion complex was estimated...
