This book comprehensively reviews the association of homocysteine metabolism with the etiology of various human disorders. The well-defined chapters embedded the central and peripheral effects of homocysteine metabolism intricately related with cardiovascular, neurodegenerative, metabolic, and autoimmune disorders. Further, it discusses the mechanisms of perturbance of cellular proteostasis by elevated homocysteine levels and provides a comprehensive account of pathophysiological consequences and clinical implications of homocysteine-containing proteins. The book also reviews association of genetic variants of homocysteine metabolic genes with type 2 diabetes mellitus and obesity. It also describes the molecular mechanism of hyperhomocysteinemia in the negative/feedback regulation of neural stem cell proliferation and alterations in DNA methylation. Taken together, it summarizes the mechanisms of hyper homocysteinemia-induced endothelial dysfunction and physiological functions of hydrogen sulfide as the protective agent.

Dengue fever (DF) is an emerging mosquito borne viral disease and important public health problem in low land of Terai region which is also expanding to hilly region. This study was designed to estimate sero-prevalence of dengue virus infection in the post monsoon period (Jun-Dec) of 2010 in Nepalese patients with fever visiting hospitals of Birganj, Damouli, Biratnagar and Dhading Besi. Serum samples were collected from 280 patients visiting hospitals with history of fever & clinically suspected DF. The sero-prevalence of dengue virus specific IgM was determined by enzyme linked immunosorbent assay (ELISA) kit (SD, Korea). Molecular diagnosis based on RT-PCR was also performed for the confirmatory diagnosis. The IgM capture ELISA has become the most accepted technique for the diagnosis of dengue in developing countries like Nepal.
