There has been a major expansion of social security programs in India during the last 15. years or so, along with wider recognition of economic and social rights. This paper discusses five programs that can be seen as partial foundations of a possible social security system for India: school meals, child care services, employment guarantee, food subsidies, and social security pensions. The record of these programs varies a great deal between Indian states, but there is growing evidence that they make an important contribution to human well-being, and also that the achievements of the leading states are gradually spreading to other states as well. Much scope remains for extending these efforts: despite the recent expansion, India's social security system is still very limited in international perspective. The paper also discusses some general issues of social policy in India, such as the arguments for universalization versus targeting and the value of a rights approach to social security. © 2017 Elsevier Ltd.

The present study was conducted to study the ameliorating effect of Nigella sativa seed oil (5ml/ kg body weight, 10 ml/kg body weight) on the liver damage caused by thioacetamide (20 mg/kg body weight) in albino rats for a period of eight week. A significant (p<0.05) improvement in the altered levels of bilirubin, albumin, total protein, alanine transaminase, alkaline phosphatase, y-glutamyl transferase was observed after treatment with 10 ml/kg body weight of Nigella sativa oil. Antioxidant enzymes like catalase, superoxide dismutase glutathione peroxidase, thiobarbituric acid reactive substances and reduced glutathione also showed significant improvement in their altered levels in Nigella sativa (10 ml/kg body weight) treated rats. The results confirm the ameliorating effect of Nigella sativa oil on liver injury caused by thioacetamide and suggest the ability of Nigella sativa oil in scavenging the free radicals and protecting the liver cell against oxidative damage. The histopathological examination of liver section also confirm the ability of Nigella sativa oil in decreasing the severity of histopathological injury caused by thioacetamide.

The last decade has witnessed a mammoth progress in the area of brain ageing. Recent gene profiling and brain imaging techniques have made it possible to explore the dark areas of ageing neurons in a new molecular perspective. Many conserved pathways and cellular and molecular mechanisms particularly nuclear mitochondrial molecular interactions are known now. Disruptions in mitochondrial function and reduction in cellular antioxidative and immunoproteins contribute to generation of reactive oxygen species (ROS) which leads to deteriorated adult neurogenesis, reduced white matter and compromised neural plasticity. The overall deteriorated structure and function of neurons is manifested in form of cognitive decline and prolonged neurodegenerative disorders. Dietary restrictions (DR), physical and mental activities however have been shown to counter these ailments. However more precise molecular dynamics at protein levels is still debatable which is the future task for neuroscientists.

Agriculture is extremely sensitive to climate and weather conditions. The resilience of our crop production systems to changes in climate can be enhanced by improved understanding impacts and responses of crops to changing climates. Several countries in Asia and Africa are at the risk of losing about 280 million tons of potential cereal production as a result of climate change factor, particularly increasing temperatures and prolonged dry periods. The most significant negative changes for developing countries in Asia, where agricultural production declines of about -4% to -10% are anticipated under different socioeconomic and climate change scenarios. Rising temperatures will reduce the amount of fertile farmland, and by 2050, the amount of maize grown is expected to decline by 6-23% and wheat by 40-45%. The majority of the world's food supply comes from the consumption of seeds from grain crops (wheat, rice, maize, soybean, barley, and sorghum), which are most vulnerable to changing climates. The growth in food production is lower than the population growth; therefore, there will be challenges of food security. Major impacts of climate change will be on rain-fed crops that account for nearly 60% of cropland area. As predicted, South Asia and sub-Saharan Africa will be highly vulnerable to climate change. Crop production can be increased by the use of quality seeds of high-yielding stress-tolerant varieties, combined with judicious use of inputs, particularly water and nutrients. Climate changes affect all four dimensions of food security, that is, availability, access to food, stability of food supplies, and food utilization. The seed industry plays an important role in increasing food production. It provides high-quality seeds of high-yielding varieties in adequate quantities at the right time and right place. Climate change influences the population dynamics of insects, emergence of new pests, changing status of pest and disease development, and evolution of new races of pests. Quality seed production is also affected by crop/weed interactions, loss of pollinator biodiversity, and genetic diversity. The seed crop is also affected by climate change regarding change in crop phenology, reproduction, flowering, anthesis/pollen viability, and pollination/fertilization, length of seed-filling duration, seed setting, seed size, seed dormancy, seed yield, and ultimately seed quality. Therefore, the cost of seed production is likely to increase in changing climate due to scheduling of operations, land and water management, herbicide/insecticide applications, pollination management, and postharvest seed management. Issues regarding intellectual property rights (IPR) related to seed, including patent infringements, prevalence of monocultures, consolidations of transnational corporations through acquisitions and mergers, and biodiversity and pollinator-loss related issues further complicate the problem. The lack of trained conventional plant breeders, crop physiologists, and seed technologists and stronger interdisciplinary collaboration between agronomists and biologists need attention. Further, acceptance of engineered crop or seed, increasing cost of genetically engineered (GE) seed as compared with conventional seed with no yield advantage, increasing number of herbicide applications, culminate in loss in net farm income in developed countries. In this article, the issues regarding the impact of climate change (particularly increasing temperature and carbon dioxide concentrations) on seed production, the present trend of the global seed industry, are discussed. © 2013 Elsevier Inc.

This article attempts to resolve the puzzle of public distribution system leakages using the latest available data. Leakages remain high, but there is clear evidence of improvement in recent years, especially in states - including Bihar - that have undertaken bold PDS reforms. The main source of leakages is the "above the poverty line" quota, which is due to be phased out under the National Food Security Act.

Expert Opinion on Therapeutic Patents | Year: 2014
Introduction: Oral-controlled and modified-release drug delivery systems with zero-order sustained-release kinetics have been developed and proven suitable for meeting increasingly sophisticated therapeutic needs. Nevertheless, the impact of basic chronobiology concepts on the practice of medicine is still ongoing and to address chronotherapy needs, various types of pulsatile drug delivery systems have been innovated. The purpose of this review is to highlight these innovations in the field of chronotherapy.Areas covered: The present review discusses in depth on recent patents and developments related to pulsatile drug delivery systems with eroding, soluble or rupturable barrier coatings, and systems with capsular structures. Besides focusing on all recent innovations, the review addresses the novelty and feasibility of all upcoming technologies being exploited considering pulsatile drug delivery systems.Expert opinion: There has been a growing interest in pulsatile delivery, which generally refers to the liberation of drugs following a programmable and well-defined lag phase from the time of administration. From 1981 until the present date, patent publications related to pulsatile drug delivery have shown more promising systems with numerous developments in arena of drug delivery. Future development of chronotherapeutic medications requires proper assessment and integration with other emerging disciplines such as hydrogel and transdermal delivery systems. The selection of the appropriate chronopharmaceutical technology should take into considerations with the ease of manufacturing and the cost-effectiveness. © 2014 Informa UK, Ltd.

Exact solutions are obtained for a collective model of two identical two-level atoms interacting with a quantized bimodal field with intensity-dependent coupling terms in a lossless cavity. A unitary transformation method is used to solve the time-dependent problem that also gives the eigensolutions of the interaction Hamiltonian. The atomic population dynamics and the dynamics of the photon statistics of the two cavity modes are studied. We present evidence of cooperative effects. © 2012 American Physical Society.

The present study was carried out to analyze the differences in the activity of hormone stanniocalcin (STC) between male and female fishes of Mastacembelus armatus during their gonadal cycle. A large variation in nuclear diameter of cells of corpuscles of Stannius (CS) were recorded in relation to testicular cycle as well as ovarian cycle which indicates that the cellular activity varied with different phases of reproductive cycle in both male and female fish. Similar changes in nuclear diameter of CS cells were also observed after 17alpha-methyltestosterone administration in males and 17 β-estradiol administrations in females. A positive correlation was observed between plasma STC levels, gonadosomatic index (GSI) and the sex steroids in both sexes, suggesting that STC has a role in the processes involved in gonadal development. In addition females showed remarkable changes in plasma calcium level during gonadal cycle while no such change for males were observed. In females the plasma calcium level estimated during different phases of reproductive cycle indicates positive correlation between plasma level of calcium and gonad growth. Thus hyperactivity of CS cells was noted in both male and female fishes during gonadal cycle along with the differences in the activity of STC as well. In female it may act as hypocalcemic factor and bring the level of calcium to normal which increases during preparatory and pre spawning phases to fulfill the increased demand of calcium for vitellogenesis. However data of male fishes indicated that plasma STC concentration varied widely during gonadal cycle but showed no consistent relationship to plasma calcium level. © 2014 Verma, Alim.

Transfer of the naturally occurring radionuclides 238U, 232Th, and 40K, and the fallout radionuclide 210Po to different wild plant species in the rainforest of Western Ghats was analyzed. A number of physiologically different plants from the top storey and understorey, such as shrubs and epiphytes, were compared. The concentrations of these radionuclides in the plants and soil were measured using a gamma ray spectrometer and an alpha counter, and were found to vary widely within plants and between species. The soil-plant ratios also varied between species while Elaeocarpus oblongus and epiphytic plants exhibited preferential uptake of these radionuclides. As a result, the dust particles trapped in the root systems of epiphytes could be used as bioindicators of fallout radionuclides in the Western Ghats. •Predominant plants species of the region were selected for analysis.•CR Model was employed to these plants spices.•Two plants were indicated preferential uptake of these radionuclides.•Bioindicator was identified in the Western Ghats Environment. © 2014 Elsevier Ltd.
