Treatment of multidrug-resistant tuberculosis has become one of the major problems in public health. Understanding the molecular mechanisms of drug resistance has been central to tuberculosis research in recent times. DNA microarray technology provides the platform to study the genomic variations related to these mechanisms on a comprehensive level. To(More)
BACKGROUND The objective of this study is to evaluate the efficacy of oral glutamic acid supplementation in promoting hypoxic tolerance. METHODS The experiments were conducted in albino rats by exposing them to three levels of hypoxia in a simulated environment for varying periods of time. The parameters studied include: gasping time at 35,000 ft (10,668(More)
BACKGROUND & OBJECTIVE Fluoroquinolones (FQs) are important drugs used for treatment of drug resistant tuberculosis and are also now being considered as first line drugs to shorten the duration of treatment of tuberculosis (TB). In order to find out useful FQs for treatment of tuberculosis, the comparative efficacy of five FQs, namely, ofloxacin (OFL),(More)
Studies on adaptation to high altitude (HA) of 3500 m in the Himalayas were conducted in three phases, each including 10 normal and healthy males normally resident at sea-level. Phase I subjects had no previous experience of HA, phase II subjects after 4-6 months at HA were airlifted to sea-level and phase III subjects stayed continuously for 6 months at(More)
Leprosy is a disease caused by Mycobacterium leprae. Various modes of transmission have been suggested for this disease. Transmission and risk of the infection is perhaps related to presence of the infectious cases and is controlled by environmental factors. Evidence suggests that humidity may favor survival of M. leprae in the environment. Several reports(More)
BACKGROUND & OBJECTIVES In drug resistant, especially multi-drug resistant (MDR) tuberculosis, fluoroquinolones (FQs) are used as second line drugs. However, the incidence of FQ-resistant Mycobacterium tuberculosis is rapidly increasing which may be due to extensive use of FQs in the treatment of various other diseases. The most important known mechanism(More)
BACKGROUND This study mainly focused on renal blood flow, hematological parameters, blood gases, and blood pH, which are affected on exposure to moderate (3500 m) and extreme altitudes (5800 m) in sea level residents. HYPOTHESIS Acute and prolonged exposure to high or extreme altitude may cause pathophysiological changes in kidney and renal plasma/blood(More)
