PURPOSE Chronic hyperglycemia and hypoxemia are believed to be causal factors in the development of proliferative diabetic retinopathy (PDR) among individuals with type 2 diabetes. It is hypothesized that formation of new blood vessels in the retina due to prolonged hypoxia is associated with increased expression of several growth factors and angiogenic(More)
PURPOSE The aim of the present study was to evaluate the collective role of N-epsilon-carboxy methyl lysine (N(ε)-CML), advanced glycation end-products (AGEs), and reactive oxygen species (ROS) for the development of retinopathy among type 2 diabetic subjects. METHODS Seventy type 2 diabetic subjects with nonproliferative diabetic retinopathy (NPDR), 105(More)
BACKGROUND Implementation of Multi drug Therapy (MDT) regimen has resulted in the decline of the total number of leprosy cases in the world. Though the prevalence rate has been declining, the incidence rate remains more or less constant and high in South East Asian countries particularly in India, Nepal, Bangladesh, Pakistan and Srilanka. Leprosy,(More)
Active pulmonary tuberculosis (APTB) is associated with a failure of the host immune system to control the invading Mycobacterium tuberculosis (Mtb). The objective of this study was to quantify and assess the role of serum inflammatory cytokines in active pulmonary tuberculosis patients following anti-tuberculosis drug (ATD) therapy. Blood samples were(More)
Mycobacteria are aerobic, nonspore forming, non-motile,single-cell bacteria.Of more than 40 currently recognized species of mycobacteria, Mycobacterium tuberculosis, the causative agent of human TB is the commonest pathogen for pulmonary and extra pulmonary tuberculosis cases. The other members of the Mycobacterium tuberculosis complex (MTC) or the(More)
PURPOSE To evaluate the role of interleukin-6 (IL-6) in the inflammatory and proliferative stages of Eales' disease (ED) and to determine the influence of IL-6-174G/C polymorphism in the IL-6 and IL-6-regulated protein expression, as well as the development of ED. METHODS One hundred and twenty-one patients diagnosed with ED, 223 matched healthy controls,(More)
Type 2 diabetes mellitus is a complex metabolic disorder with adverse cardiovascular risk. The role of micronutrients has not yet been well clarified in this condition, especially in India.THE OBJECTIVES OF THIS STUDY WERE TO: (1) evaluate chromium status in Indian subjects with type 2 diabetes mellitus, (2) assess the effect of chromium picolinate (200(More)
BACKGROUND Chlamydia trachomatis is recognized as one of the most common sexually transmitted pathogen in the world. 50-80% of infected females are asymptomatic. These untreated women are at risk of developing chronic sequelae leading to tubal pathology causing infertility. Infertility is defined as 1 year of unprotected intercourse without pregnancy. It(More)
PURPOSE New blood vessel formation in the retina because of prolonged hypoxia is believed to be directly associated with increased expression of several growth factors and angiogenic cytokines. In the present study, we made an attempt to investigate the possible association of the promoter polymorphisms of interleukin 6, tumor necrosis factor α, and(More)
For early detection and species differentiation of mycobacteria, polymerase chain reaction (PCR) techniques are currently in wide use. However, individual techniques using amplification of different targets with appropriate primers still have some limitations, which have to be overcome. The ideal technique would use DNA sequences which should be present in(More)
