Because of the widespread phenomenon of patrilocality, it is hypothesized that Y-chromosome variants tend to be more localized geographically than those of mitochondrial DNA (mtDNA). Empirical evidence confirmatory to this hypothesis was subsequently provided among certain patrilocal and matrilocal groups of Thailand, which conforms to the isolation by(More)
BACKGROUND Whipple disease is a chronic infection caused by Tropheryma whipplei. Trimethoprim-sulfamethoxazole is recommended for treatment of Whipple disease but is associated with treatment failure. T. whipplei is resistant in vitro to trimethoprim, because the gene targeted by this agent is missing. METHODS A patient experienced clinical failure during(More)
Leaf curl disease is a serious constraint in tomato production throughout India. Several begomoviruses were reported from different parts of the country; however, identity of begomovirus associated with leaf curl disease in tomato in north-eastern states of India was obscured. In the present study, the complete genome of an isolate (To-Ag-1) of begomovirus(More)
Antimicrobial treatments result in the host's enteric bacteria being exposed to the antimicrobials. Pharmacodynamic models can describe how this exposure affects the enteric bacteria and their antimicrobial resistance. The models utilize measurements of bacterial antimicrobial susceptibility traditionally obtained in vitro in aerobic conditions. However, in(More)
Ubiquitin (Ub), a protein consisting of 76 amino acid residues which is present in all eukaryotic cells tested (Rech-steiner, 1987), plays a role in the degradation of abnormal and short-lived proteins by the ATP-and Ub-dependent proteolytic systems (Hershko et al., 1980). Ubiquitination of histone 2A varies during the course of the cell cycle (Matsui et(More)
