Polyphenols and polyphenol-rich fractions of plants have been reported to have protective effects against lipid peroxidation,
most probably by serving as scavengers of free radicals and/or by chelating metal ions. In the present study, the effect of
different extracts/subfractions of Chickrassy (Chukrasia tabularis) on peroxyl radical mediated damage to the polyunsaturated fatty acids was investigated. Liver homogenate was used as experimental
material. The production of malondialdehyde served as a marker of lipid peroxidation and oxidative stress. It was observed
that polyphenol-rich fractions, particularly the ethyl acetate fractions of bark and leaves, showed the highest protective
activity of 83.02% and 88.62% inhibition, respectively. This study will help in knowing the scientific validation of this
plant, for its use in ayurvedic formulations.
The current in vitro experiments performed herewith comply with the current laws of India. 相似文献

In recent years field test kits have been largely used to identify arsenic (As) levels in contaminated water sources in Bangladesh,
West Bengal (India), and elsewhere in the world to establish whether or not the water is safe. Most of the kits are based
on the reaction of arsine gas with some chemical agent to form a coloured complex; the intensity of the colour is compared
visually with a colour-coded chart or measured electronically to calculate the concentration of As in the water sample. In
this paper, a step-wise review is presented of the analytical process used in the most commonly available As field test kits
and the associated shortcomings of each of these kits. We also identify the research gaps for future work to enhance the accuracy
and reliability of test results produced by these kits. 相似文献

This paper presents projections of motor vehicles, oil demand, and carbon dioxide (CO2) emissions for India through the year 2040. The populations of highway vehicles and two‐wheelers are projected under three different scenarios on the basis of economic growth and average household size in India. The results show that by 2040, the number of highway vehicles in India would be 206‐309 million. The oil demand projections for the Indian transportation sector are based on a set of nine scenarios arising out of three vehicle‐growth and three fuel‐economy scenarios. The combined effects of vehicle‐growth and fuel‐economy scenarios, together with the change in annual vehicle usage, result in a projected demand in 2040 by the transportation sector in India of 404‐719 million metric tons (8.5‐15.1 million barrels per day). The corresponding annual CO2 emissions are projected to be 1.2‐2.2 billion metric tons. 相似文献

The Cropland Data Layers (CDL) are high-resolution geo-referenced data products made available by the U.S. Department of Agriculture. However, the CDL lacks in its ability to be employed as a tool to identify the impact of the gradually evolving drivers of land use change, e.g., climate change, due to its limited historical depth. We implement a robust, phenology-based satellite image classification algorithm to identify historical cropland allocation in eastern South Dakota and North Dakota predating the initial CDL by 13 and 22 years, respectively. Five major land covers, i.e., corn, soybeans, wheat, alfalfa and grass (including native grass, hay and pasture) are identified using archived Landsat-5 surface reflectance data, while achieving CDL-like accuracy. The long-term rate of grassland loss during 1985–2011 is found to be significantly lower (26,781 hectares or 1.5% annually) relative to the near-term rate of grassland loss during 2006-’11 (84,545 hectares or 5.2% annually). We find similar discrepancy in regional corn expansion rates. Our value-added raster data provide opportunities for improved identification of land use drivers, whereas relying solely on the CDL’s restricted historical extent may lead to biased land use change estimates and misguide policy. 相似文献
