Phenols, a major group of antioxidant phytochemicals, have profound importance due to their biological and free radical scavenging activities. To identify their potential sources, extracts of some plants were studied for their total phenolic content (TPC), antioxidant (AOA) and free radical scavenging activities (FRSA) by different methods at multiple(More)
The aqueous extract of leaf (LE), fruit (FE) and seed (SE) of Moringa oleifera was assessed to examine the ability to inhibit the oxidative DNA damage, antioxidant and anti-quorum sensing (QS) potentials. It was found that these extracts could significantly inhibit the OH-dependent damage of pUC18 plasmid DNA and also inhibit synergistically with trolox,(More)
In order to determine antioxidant activity, the five extracts/fractions of red onion peel were studied for their total content of phenolics (TPC), flavonoids (TFC), antioxidant activity (AOA), free radical scavenging activity (FRSA), assayed by DPPH radical in the terms of anti-radical power (ARP) and reducing power (RP), expressed as ascorbic acid(More)
Thyroid hormone (TH) deficiency leads to extensive apoptosis during cerebellar development, but the mechanism still remains unclear. Different signals also converge on mitochondria during apoptosis to induce the release of apoptogenic proteins that activate proteolytic cascade through specific enzymes called caspases. Here we studied the effect of(More)
Phenols, a major group of antioxidant phytochemicals, have profound importance due to their biological and free radical scavenging activities. To identify their potential sources extracts of some fruits and their different parts were studied for total phenolic contents (TPC), antioxidant (AOA) and free radical scavenging activities (FRSA). The amount of TPC(More)
Thyroid hormone (TH) deficiency results in delayed proliferation and migration of cerebellar granule cells. Although extensive cell loss during the development of the cerebellum under hypothyroid conditions is known, its nature and its mechanism are poorly understood. Bcl-2 family gene expression is known to determine the fate of cells to undergo apoptosis.(More)
The majority of idiopathic pleural effusion are considered to be of tuberculous etiology. The culture of bacilli provide most authentic evidence of disease process. This study was carried out on 21 cases of suspected tuberculous pleural effusion. The pleural fluid and tissue was subjected for smear examination, and cultivation of tubercle bacilli along with(More)
Twenty five chilli genotypes from North East region of India evaluated showed variation for capsaicin from 0.27% (CHF-CA-1) to 3.03% (CHF-CA-21), oleoresin content from 2.49% (CHF-CA-5) to 9.26% (CHF-CA-18) with high to moderate ascorbic acid. Total phenolics ranged from 5.1 (CHF-CA-8) to 26.8 (CHF-CA-23) mg GAE/g and total carotenoids from 0.09 (CHF-CA-16)(More)
Study on genetic diversity was conducted with 30 chilli (Capsicum annuum L.) genotypes of Indian origin at the research farm of Vegetable Science, College of Horticulture and Forestry, Central Agricultural University, Pasighat, Arunachal Pradesh, India during March-October 2011. Twelve quantitative characters viz. plant height (cm), number of primary branch(More)
