A disturbance in the activity of the hypothalamic-pituitary-adrenal (HPA) axis has been reported among individuals with HIV-1 infection. However, these studies have been carried out in the West where the infecting clade is clade B. HIV-1 infection is rapidly spreading in various parts of South East Asia, including India, where the HIV-1 infecting clade is largely clade C. An investigation of HP...

In Egypt, the seed and pollen grain morphology of genus Tephrosia Pers. were studied using light scanning electron microscopy. Qualitative quantitative characters seeds grains are presented. The data suggest that several morphological can distinguish taxa Tephrosia. Based on UPGMA clustering analysis PCA, three main clades recognized: Clade A comprising T. kassasii, clade B apollinea, purpurea,...

Candida albicans grows within a wide range of host niches, and this adaptability enhances its success as a commensal and as a pathogen. The telomere-associated TLO gene family underwent a recent expansion from one or two copies in other CUG clade members to 14 expressed copies in C. albicans. This correlates with increased virulence and clinical prevalence relative to those of other Candida cla...

Reef-building corals switch endosymbiotic algae of the genus Symbiodinium during their early growth stages and during bleaching events. Clade C Symbiodinium algae are dominant in corals, although other clades - including A and D - have also been commonly detected in juvenile Acroporid corals. Previous studies have been reported that only molecular data of Symbiodinium clade were identified with...

background: crimean congo hemorrhagic fever virus (cchfv) is a member of the bunyaviridae family and nairovirus genus. it has a negative-sense, single stranded rna genome approximately 19.2 kb, containing the small, medium, and large segments. cchfvs are relatively divergent in their genome sequence and grouped in seven distinct clades based on s-segment sequence analysis and six clades based o...

Oysters, with high levels of phenotypic plasticity and wide geographic distribution, are a challenging group for taxonomists and phylogenetics. Our study is intended to generate new EST-SNP markers and to evaluate their potential for cross-species utilization in phylogenetic study of the genus Crassostrea. In the study, 57 novel SNPs were developed from an EST database of C. gigas by the HRM (h...

HIV-1 clades are known to be one of the key factors implicated in modulating HIV-associated neurocognitive disorders. HIV-1 B and C clades account for the majority of HIV-1 infections, clade B being the most neuropathogenic. The mechanisms behind HIV-mediated neuropathogenesis remain the subject of active research. We hypothesized that HIV-1 gp120 clade B and C proteins may exert differential p...

We examined the genetic structure of populations of an ambrosia beetle, Xylosandrus brevis (Eichhoff) (Curculionidae: Scolytinae), to understand its colonization dynamics. We collected specimens from 20 sites in Japan and studied the genetic structure of these populations using portions of the mitochondrial cytochrome oxidase I gene (COI). A phylogenetic analysis showed three distinct lineages ...
