Different groups of pregnant rats were treated with diazepam (10 mg/kg), phenobarbital (10 mg/kg), haloperidol (0.1 mg/kg), fluoxetine (10 mg/kg) and vehicle (normal saline) intraperitoneally once a day during gestation days 13 to 21. After birth these pups were culled to 8 pups/dam and foster-nursed by lactating mothers for 3 weeks and were reared in(More)
The unzipping transition under the influence of external force of a dsDNA molecule has been studied using the Peyrard-Bishop Hamiltonian. The critical force F(c)(T) for unzipping calculated in the constant force ensemble is found to depend on the potential parameter k which measures the stiffness associated with a single strand of DNA and on D, the well(More)

Effect of defects on the melting profile of short heterogeneous DNA chains is calculated using the Peyrard-Bishop Hamiltonian. On-site potential on a defect site is represented by a potential that has only a short-range repulsion and a flat part without well of the Morse potential. Stacking energy between two neigbouring pairs involving a defect site is(More)
PURPOSE Peripherally inserted central catheters (PICCs) have become an essential component of the management of an increasing number of patients, including patients who may require hemodialysis. Reported symptomatic venous thrombosis rates associated with PICC lines are based on clinical signs and symptoms and range from 1% to 4%. The purpose of this study(More)
Two genes with sequence homology to those encoding protein tyrosine phosphatases were cloned from genomic DNA of Mycobacterium tuberculosis H(37)Rv. The calculated molecular masses of these two putative tyrosine phosphatases, designated MPtpA and MPtpB, were 17. 5 and 30 kDa, respectively. MPtpA and MPtpB were expressed as glutathione S-transferase fusion(More)
The accepted standard treatment of war wounds through the last century has been debridement and delayed primary closure. However, recently, there has been a renewed Interest In primary closure of these wounds. 1481 war wounds were managed by the authors and out of 789 soft tissue injuries, 389 (47%) were closed primarily (group 1) after meticulous(More)
We describe four cases of disseminated infection caused by endemic Penicillium marneffei in human immunodeficiency virus (HIV)-infected patients from the Manipur state of India. The most common clinical features observed were fever, anorexia, weight loss, hepatosplenomegaly, and, more importantly, skin lesions resembling molluscum contagiosum. The diagnosis(More)
India is considered to have a low incidence of HIV infection so far. Nevertheless, an epidemic of HIV infection has been reported recently among intra-venous drug users (IVDUs) in Manipur, a north-eastern state of India, bordering Myanmar (Burma). This report describes the epidemiology of intravenous drug abuse in the state of Manipur. Four hundred and(More)
Siri cattle, a dual purpose breed of India is currently showing declining population trend. Siri animals have been developing through natural selection and show high adaptation to wide range of hilly terrain (altitudes 150-2500 m). The present work evaluated the genetic diversity of 23 FAO recommended microsatellite loci in a sample of 50 animals. The(More)
Pathogenesis of Mycobacterium tuberculosis is closely connected to its survival and replication within the host. Some pathogenic bacteria employ protein kinases that interfere with the cellular signalling network of host cells and promote bacterial survival. In this study, the pknF and pknG genes, which encode two putative protein kinases of M. tuberculosis(More)
