Human immunodeficiency virus type 1 (HIV-1) may be studied by molecular or immunological approaches. Most analyses have been performed by genetic comparison of isolates and have led to the definition of clades or subtypes within the major (M) group of HIV-1. Five subtypes (A to E) were initially identified by comparison of genomic sequences. Four new subtypes (F to I) were identified more recen...
The development of viral diversity during the course of human immunodeficiency virus type 1 (HIV-1) infection may significantly influence viral pathogenesis. The paradigm for HIV-1 evolution is based primarily on studies of male cohorts in which individuals were presumably infected with a single virus variant of subtype B HIV-1. In this study, we evaluated virus evolution based on sequence info...
in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
Sir, This correspondence attempts to clarify two important issues relevant to the DNA barcoding initiative raised in Waugh’s otherwise, cogent and useful review. The first issue concerns the way that Waugh presents the analytic approach to DNA-barcoding data, and the second involves a broader issue with respect to the role of DNA barcoding in modern biology. Both issues are of great importance ...
