There has been a tendency for many researchers and health professionals examining HIV transmission in South Africa to focus on explanations that specifically implicate culture as a primary vector affecting the prevalence of high-risk sexual behavior, such as multiple partners, unprotected sex, and dry sex. In contrast, the residents of Orange Farm, a former informal settlement south of Soweto, portray culture as seldom, if ever, motivating actions that are associated with HIV transmission or prevention in the community. Comparing and contrasting these differing conceptions, we comment critically on the use of ideas regarding culture in explanations addressing the HIV/AIDS pandemic in sub-Saharan Africa.

The bagrada bug, Bagrada hilaris (Burmeister), is an emerging agricultural pest in the Americas, threatening agricultural production in the southwestern United States, Mexico and Chile, as well as in the Old World (including Africa, South Asia and, more recently, Mediterranean areas of Europe). Substantive transcriptomic sequence resources for this damaging species would be beneficial towards understanding its capacity for developing insecticide resistance, identifying viruses that may be present throughout its population and identifying genes differentially expressed across life stages that could be exploited for biomolecular pesticide formulations. This study establishes B.

Background: Breast cancer is a significant global health issue, responsible for a large number of female cancer deaths. Early detection through breast cancer screening is crucial in reducing mortality rates. However, regions such as Sub-Saharan Africa (SSA) face challenges in identifying breast cancer early, resulting in higher mortality rates and a lower quality of life.

Purpose: This study aimed to assess the current regulatory review process of the Zambia Medicines Regulatory Authority (ZAMRA) by identifying the key milestones and target timelines achieved for products approved from 2020 to 2023, as well as good review and quality decision-making practices implemented in the review process.
Methods: A standardised, validated questionnaire; Optimising Efficiencies in Regulatory Agencies (OpERA) and the OpERA Data Collection Template were completed by the author.
Results: Three review models are used by ZAMRA to review new active substances (NASs) and generic products: verification, for products prequalified by the World Health Organization or approved by a stringent regulatory authority (SRA); abridged, for well-established molecules or SRA-approved products; or full, for products not otherwise prequalified.

In the present study 1,709 cattle, including 1,118 Drakensberger (DRB), 377 Nguni (NGI), and 214 Tuli (TUL), were genotyped using the GeneSeek® Genomic Profiler™ 150 K bovine SNP panel. A genomic data set of 122,632 quality-filtered single nucleotide polymorphisms (SNPs) were used to identify selection signatures within breeds based on conserved runs of homozygosity (ROH) and heterozygosity (ROHet) estimated with the detectRUNS R package. The mean number of ROH per animal varied across breeds ranging from 36.
