Free Radicals in Human Health and Disease
The role of oxidative stress in human disease has become an area of intense interest. Free radicals, a normal product of metabolism, exist in all aerobic cells in balance with biochemical antioxidants. Environmental stress increases the levels of free radicals drastically, thereby disturbing the equilibrium between free radical production and the antioxidant capability causing oxidative stress. Over the years, ROS has been implicated in the pathologies of various diseases like cancer, neurological disorder, cardiovascular diseases rheumatoid arthritis, diabetes etc. This book provides an in depth critical state-of-art reviews from established investigators on free radicals, ROS associated pathogenesis of human diseases, biomarkers of oxidative damage, antioxidants, phytonutrients and other related health concerns of modern society.The present book is aimed at graduate students, researchers in academia, industry and clinicians with the interest in redox biology. Special attention has been devoted to the topic of ROS signalling, oxidative stress induced human pathologies & antioxidative therapies. The book consists of four parts in specified topics based on the current literatures for the better understanding of the readers with respect to their subject-wise interests. The first section of the book provides an overview about the ROS production and their measuring tools and techniques followed by the mechanisms involved in the oxidative stress in the second section. The third section describes the involvement of oxidative stress in different human diseases and the last section focuses on the different strategies to ameliorate oxidative stress induced stress.

Nuclear Strategy in the Modern Era
The world is in a second nuclear age in which regional powers play an increasingly prominent role. These states have small nuclear arsenals, often face multiple active conflicts, and sometimes have weak institutions. How do these nuclear states--and potential future ones--manage their nuclear forces and influence international conflict? Examining the reasoning and deterrence consequences of regional power nuclear strategies, this book demonstrates that these strategies matter greatly to international stability and it provides new insights into conflict dynamics across important areas of the world such as the Middle East, East Asia, and South Asia. Vipin Narang identifies the diversity of regional power nuclear strategies and describes in detail the posture each regional power has adopted over time. Developing a theory for the sources of regional power nuclear strategies, he offers the first systematic explanation of why states choose the postures they do and under what conditions they might shift strategies. Narang then analyzes the effects of these choices on a state's ability to deter conflict.Using both quantitative and qualitative analysis, he shows that, contrary to a bedrock article of faith in the canon of nuclear deterrence, the acquisition of nuclear weapons does not produce a uniform deterrent effect against opponents. Rather, some postures deter conflict more successfully than others. Nuclear Strategy in the Modern Era considers the range of nuclear choices made by regional powers and the critical challenges they pose to modern international security.

Fragile Balance of Terror
In The Fragile Balance of Terror, the foremost experts on nuclear policy and strategy offer insight into an era rife with more nuclear powers. Some of these new powers suffer domestic instability, others are led by pathological personalist dictators, and many are situated in highly unstable regions of the world—a volatile mix of variables.The increasing fragility of deterrence in the twenty-first century is created by a confluence of forces: military technologies that create vulnerable arsenals, a novel information ecosystem that rapidly transmits both information and misinformation, nuclear rivalries that include three or more nuclear powers, and dictatorial decision making that encourages rash choices. The nuclear threats posed by India, Pakistan, Iran, and North Korea are thus fraught with danger.The Fragile Balance of Terror, edited by Vipin Narang and Scott D. Sagan, brings together a diverse collection of rigorous and creative scholars who analyze how the nuclear landscape is changing for the worse. Scholars, pundits, and policymakers who think that the spread of nuclear weapons can create stable forms of nuclear deterrence in the future will be forced to think again.Contributors: Giles David Arceneaux, Mark S. Bell, Christopher Clary, Peter D. Feaver, Jeffrey Lewis, Rose McDermott, Nicholas L. Miller, Vipin Narang, Ankit Panda, Scott D. Sagan, Caitlin Talmadge, Heather Williams, Amy Zegart

Seeking the Bomb
The first systematic look at the different strategies that states employ in their pursuit of nuclear weaponsMuch of the work on nuclear proliferation has focused on why states pursue nuclear weapons. The question of how states pursue nuclear weapons has received little attention. Seeking the Bomb is the first book to analyze this topic by examining which strategies of nuclear proliferation are available to aspirants, why aspirants select one strategy over another, and how this matters to international politics.Looking at a wide range of nations, from India and Japan to the Soviet Union and North Korea to Iraq and Iran, Vipin Narang develops an original typology of proliferation strategies—hedging, sprinting, sheltered pursuit, and hiding. Each strategy of proliferation provides different opportunities for the development of nuclear weapons, while at the same time presenting distinct vulnerabilities that can be exploited to prevent states from doing so. Narang delves into the crucial implications these strategies have for nuclear proliferation and international security. Hiders, for example, are especially disruptive since either they successfully attain nuclear weapons, irrevocably altering the global power structure, or they are discovered, potentially triggering serious crises or war, as external powers try to halt or reverse a previously clandestine nuclear weapons program.As the international community confronts the next generation of potential nuclear proliferators, Seeking the Bomb explores how global conflict and stability are shaped by the ruthlessly pragmatic ways states choose strategies of proliferation.

Matter of Belief
‘Nagaland for Christ’ and ‘Jesus Saves’ are familiar slogans prominently displayed on public transport and celebratory banners in Nagaland, north-east India. They express an idealization of Christian homogeneity that belies the underlying tensions and negotiations between Christian and non-Christian Naga. This religious division is intertwined with that of healing beliefs and practices, both animistic and biomedical. This study focuses on the particular experiences of the Angami Naga, one of the many Naga peoples. Like other Naga, they are citizens of the state of India but extend ethnolinguistically into Tibeto-Burman south-east Asia. This ambiguity and how it affects their Christianity, global involvement, indigenous cultural assertiveness and nationalist struggle is explored. Not simply describing continuity through change, this study reveals the alternating Christian and non-Christian streams of discourse, one masking the other but at different times and in different guises.

Food Insecurity in India's Agricultural Heartland
India is home to the world's largest hungry population and has a long way to go before it is anywhere near the mammoth task of achieving the United Nations' goal of ending hunger in 2030. It is ironic that this book raises the issue of "Hunger" in a state where it is least expected. Punjab is a state with mountains of food grains and overflowing godowns, with highest yields, and largest area under irrigation. Not only that, it is the Green Revolution state of India,that has played the most prominent role in helping India achieve its goal of food self-sufficiency.By investigating the hydra-headed concept of food security in Indian Punjab, this book brings to fore the different dimensions of the deprivation of human capabilities and the intricate relationship between food security and economy, ecology, and state policy. Moreover, it is a wakeup call for India; for if, this is the state of affairs in one of the more prosperous primarily agrarian states, what would be the situation in the poorer ones? The primary objective is to divert urgent attention tothe issue of food security, as an important ingredient of human resource development. With a strong commitment to achieving the primary goal of human resource development, India's biggest burden could well become India's greatest asset in the path to inclusive development.
