Golden Research Thoughts , 2013, DOI: 10.9780/22315063
Abstract: Forest Legislations in India since the time of British has always been a source of deprivation for asegment of the society.As a result ,these experience protests from the people at many times.Ignorance of the humanaspects by the alien ruler was quite acceptable as they did not had any aim of welfare of the poor people of India.Butwhen the same outcome has come from the own people,the conflicts has gained a new momentum.The paper is anattempt to analyse the nature of various forests legislation since the time of British along with the recent shift inlegislations brought by the Indian government to mitigate the conflict.
Effect of Arsenic-induced Toxicity on Morphological Traits of Trigonella foenum-graecum L. and Lathyrus sativus L. During Germination and Early Seedling Growth

Current Research Journal of Biological Sciences , 2011,
Abstract: Effect of five different concentrations (0, 10, 20, 30 and 40 mg/L) of arsenic was studied on 11 different parameters of two important leguminous crops, namely Trigonella foenum-graecum L. (fenugreek) and Lathyrus sativus L. (grass pea) during germination and early seedling growth stage. Mean value of germination percentage, germination index and relative germination rate decreased with concomitant increase in arsenic-induced injury level in increasing concentration of arsenic in both plants and the effect was significant at 30 and 40 mg/L treatments. Fresh and dry weight of shoots, roots and their length also reduced significantly in these two treatment levels. There was significant accumulation of arsenic in tissues, and the effect was more severe on root than shoots. Based on the parameters responding to arsenic-induced stress, Arsenic Response Index (ARI) was developed for the first time in these two crops. Among the two crops, T. foenum-graecum L. exhibited better tolerance to arsenic-induced toxicity than L. sativus L. Considering mean and ARI value, 30 mg/L of arsenic was selected as toxic to L. sativus L., while the limit was 40 mg/L for T. foenum-graecum L. at the stages of germination and early seedling growth.

Abstract: Biofuel potentiality of a native Indian strain of the freshwater oleaginous microalgae A.falcatus was studied owing to its inherently high lipid content. Influences of media constituents, pH and nitrogen sources on growth (μ), total lipid (TL) content and calorific value (CV) were compared in batch culture. Bold basal medium was superior (μ = 0.498 d-1, TL = 43.6% and CV = 23.6 kJ/g) than BG11 (μ = 0.385 d-1, TL = 38.5% and CV = 19.3 kJ/g). Medium pH (≈ 7.0) and NaHCO3 (30 mg/L), were found suitable for optimum growth at light intensity 35 μmol/m2/s, temperature 25 ± 2 0C and 16 hrs light and 8 hrs dark diurnal cycles. NO3- instead of NH4+ was preferred in the range KNO3 > NaNO3 > NH4NO3 > Urea, for maximal biomass and lipid production. Maximum biomass, TL and CV (80 mg/L DCW and 42.4% and 20.6 kJ/g respectively) were determined in medium containing KNO3 (17.6 mM). A close correlation between increase in TL and CV was observed (r2 = 0.994). With further augmentations of TL and improved biomass yield the native microalga strain could be a potent candidate for biofuel production. DOI: http://dx.doi.org/10.5755/j01.erem.61.3.1423
Growth Responses and Leaf Antioxidant Metabolism of Grass Pea (Lathyrus sativus L.) Genotypes under Salinity Stress

Abstract: Response of six improved grass pea genotypes to prolonged salinity stress was investigated on seedlings grown in pot experiment using 150?mM NaCl up to 60 days of growth after commencement of treatment (DAC). NaCl exposure significantly reduced growth potential of varieties PUSA-90-2 and WBK-CB-14, but no such effect was observed in varieties B1, BioL-212 and in two mutant lines LR3 and LR4. A time-bound measurement at 15, 30 and 60 DAC revealed significant reduction in plant dry matter production, orchestrated through abnormally low capacity of leaf photosynthesis accompanied by low K+/Na+ ratio and onset of oxidative stress in all six genotypes at 15 DAC and the extension of the phenomena in PUSA-90-2 and WBK-CB-14 to 60 DAC. High superoxide dismutase (SOD) activity coupled with low ascorbate redox and declining ascorbate peroxidase (APX) and catalases (CAT) levels led to abnormal rise in H2O2 content at reproductive stage (30 DAC) in the latter two genotypes, consequently, resulting in NaCl-induced oxidative damage. H2O2 level in the rest of the four genotypes was modulated in a controlled way by balanced action of SOD, APX and CAT, preventing oxidative damage even under prolonged NaCl-exposure. Enzyme isoforms were involved in regulation of foliar H2O2-metabolism, which was critical in determining As tolerance of grass pea genotypes. 1. Introduction Soil salinity is one of the most severe abiotic stresses affecting production of the crops worldwide [1, 2]. This problem is more severe in arid and semiarid regions, and legume plants already face a notable impact of salt stress in these regions [3, 4]. The legume family is the second only to the cereals in their importance to mankind [3], but unfortunately, improvements of this group of plants for their tolerance against soil salinity stress have not kept pace with those of cereals and oil seeds. Salinity induces oxidative stress through the generation of reactive oxygen species (ROS) within the plant cells [5]. The resultant damage is generally manifested by different alterations at cellular level including membrane lipid peroxidation, electrolyte leakage, and sometimes over accumulation of hydrogen peroxide (H2O2). H2O2 is a highly diffusible ROS within plant cell and its dual roles as a stress-inducer and at the same time as a signaling molecule to upregulate primary antioxidant defense during oxidative stress have been increasingly recognized in different crops including legumes [6–8]. Among the prominent enzymatic system involved in ROS scavenging, SOD constitutes the first line of defense, but it

Journal of Tuberculosis Research (JTR) , 2015, DOI: 10.4236/jtr.2015.31003
Abstract: Efficient management of chronic illness remains a common clinical problem. Non-adherence to a prescribed medical regimen remains a tremendous barrier to the effective medical management of chronic diseases and is considered one of the most serious problems that the medical world faces in the present. Tuberculosis is one such chronic disease which has been a prevalent problem in most of the developing nations, including India. In this paper, we describe an ethnographic study conducted in the state of Assam, with the objective of deciphering the multiple factors that are associated with the failure of the treatment regimen of Tuberculosis, viz. the DOTS (Directly Observed Treatment Short course) programme under RNTCP (Revised National Tuberculosis Control Programme).

Abstract:

Background: Detection of HIV among elderly is increasing globally and this is going to be a major public health issue in recent future. In India, data regarding demographical and clinical picture of HIV among elderly are sparse more so for elderly women. Elderly individuals especially women are still largely outside the light of HIV awareness programs and represent a major portion of undiagnosed HIV infected population with a poor quality of life. Methods and Materials: This cross-sectional study was conducted at HIV clinic of a tertiary care hospital in eastern India. 567 cases (men 457, women 110) that were detected to be HIV-positive at or after age of 50 years from 2008 to 2012 were analyzed on socio-demographical and clinical basis. Results: Detection of HIV was found to be increasing (5.7% in 2008 to 12.8% in 2012) among the elderly over last five years. Illiteracy (p < 0.01), unemployment (p < 0.001), seroconcordance of spouse (p = 0.02) and widowhood (p = 0.017) were seen more among elderly women. Frailty was the most common clinical presentation among elderly men (31%) whereas most of the elderly women were asymptomatic (27%) at the time of diagnosis. Mean CD4 count among HIV infected elderly men and women were 112 cells/dl and 137 cells/dl respectively at the time of diagnosis. Conclusions: HIV in elderly is an emerging entity in India and posing elderly women a worse socioeconomic burden despite a better clinical profile at the time of presentation. Clinicians, social workers and policymakers should come forward with wider awareness program targeted for elderly HIV patients especially women.
