Large declines in HIV incidence have been reported since 2001, and scientific advances in HIV prevention provide strong hope to reduce incidence further. Now is the time to replace the quest for so-called silver bullets with a public health approach to combination prevention that understands that risk is not evenly distributed and that effective interventions can vary by risk profile. Different...
The 133,000 X g supernatant fraction prepared from ascites cells in 20 mM KCl (low CKl supernatant) contained the initiation factors EIF-1 and EIF-2 (and the elongation factore EF-1 and EF-2) but lacked EIF-3; thus, low KCl supernatant could be used to assay for EIF-3. EIF-3 was prepared from a crude initiation factor perparation (a 250 mM KCl extract of ascites cell ribosomes precipitated with...
Background: Knowledge of the frequency and distribution of dermatoses in the male genital area and the effect of circumcision on these two factors are helpful guides to a correct diagnosis. The aim of this study was to determine the prevalence of genital dermatoses in circumcised men.Methods: This cross-sectional study was done on all circumcised men complaining about skin lesions in their geni...
Background During spermatogenesis, the H2B family, member W (H2B.W) gene, encodes a testis specific histone that is co-localized with telomeric sequences and has the potential role to mediate the sperm-specific chromatin remodeling. Previously H2B.W genetic variants were reported to be involved in susceptibility to spermatogenesis impairment. In the present study, two single nucleotide polymorp...
Background: Obesity and insulin resistance refer to a clustering of various medical conditions, with a number of pathological components that contribute to the development of diabetes and cardiovascular disease. Some studies have shown that free testosterone levels are low in obese men and are inversely correlated with the degree of obesity. In addition, leptin levels increases with obesity tha...
