Artemisinin, a sesquiterpene lactone containing an endoperoxide bridge, has been isolated from the aerial parts of Artemisia annua L. plants. It is effective against both drug-resistant and cerebral malaria-causing strains of Plasmodium falciparum. The relatively low yield (0.01-0.8 %) of artemisinin in A. annua is a serious limitation to the(More)
Microsatellite DNA sequences are rapidly becoming the dominant source of nuclear genetic markers for a wide range of applications, from genome mapping to forensic testing to population studies. If misinterpretation is to be avoided, it is vital that we understand fully the way in which microsatellite sequences evolve. We have therefore compared allele(More)
PURPOSE Although oral delivery has become a widely accepted route of administration of therapeutic drugs, the gastrointestinal tract presents several formidable barriers to drug delivery. Colonic drug delivery has gained increased importance not just for the delivery of the drugs for the treatment of local diseases associated with the colon but also for its(More)
In an attempt to identify cofactors that could possibly influence the transcriptional activity of peroxisome proliferator-activated receptors (PPARs), we used a yeast two-hybrid system with Gal4-PPARgamma as bait to screen a mouse liver cDNA library and have identified steroid receptor coactivator-1 (SRC-1) as a PPAR transcriptional coactivator. We now(More)
The basic helix-loop-helix-PAS (bHLH-PAS) protein ARNT is a dimeric partner of the Ah receptor (AHR) and hypoxia inducible factor 1 alpha(HIF1 alpha). These dimers mediate biological responses to xenobiotic exposure and low oxygen tension. The recent cloning of ARNT and HIF1(homologues (ARNT2 and HIF2 alpha) indicates that at least six distinct bHLH-PAS(More)
The Ah receptor (AHR) is a ligand-activated transcription factor that is structurally related to its dimerization partner, the Ah receptor nuclear translocator (ARNT), and two Drosophila proteins, SIM and PER. All four proteins contain a region of homology now referred to as a PAS homology domain. In addition, the AHR, ARNT, and SIM harbor a basic region(More)
Enzymatic and non-enzymatic antioxidants serve as an important biological defense against environmental oxidative stress. Information on antioxidant defense in fish is meager despite that fish are constantly exposed to a myriad of environmental stress including the oxidants. This study, therefore, assesses the activities of antioxidant enzymes viz.,(More)
This random multistage cross-sectional population survey was undertaken to determine the prevalence of diabetes mellitus (DM) and impaired glucose tolerance (IGT) in subjects aged 25 years and above in India. The study was carried out in 77 centers (40 urban and 37 rural). 18363 (9008 males and 9355 females) subjects were studied. 10617 (5379 males and 5238(More)
First degree relatives of alcoholics show significantly reduced P300 amplitudes. This phenomenon is though to be a vulnerability marker of alcoholism. Relatives of alcoholics with higher family loading and early onset alcoholism are at greater risk for developing alcoholism. The high risk population may comprise subtypes differentiated by family history(More)
Mycobacteriophage Bxb1 is a temperate phage of Mycobacterium smegmatis that shares a similar genome organization to mycobacteriophage L5, although the two phages are heteroimmune. We have investigated the regulatory circuitry of Bxb1 and found that it encodes a repressor, gp69, which regulates at least two promoters, an early lytic promoter, Pleft, and the(More)
