Prevalence of Functional Disabilities and Associations Among Disabilities, Violence, and HIV Among Adolescents and Young Adults in Lesotho.

Introduction: Lesotho has the second-highest prevalence of HIV. Despite progress in achieving HIV epidemic control targets, inequities persist among certain groups, particularly associations between disability, HIV, and violence. We assessed the prevalence of disability and examined associations between disability and HIV and violence using data from the 2018 Lesotho Violence Against Children and Youth Survey (VACS).

Oxidative induction of pro-inflammatory cytokine formation by human monocyte-derived macrophages following exposure to manganese in vitro.

Manganese (as Mn(2+)), a superoxide dismutase mimetic, catalyzes the formation of the relatively stable membrane-permeable reactive oxygen species (ROS) hydrogen peroxide (H2O2), a mediator of intracellular redox signaling in immune and inflammatory cells. The goal of this study was to investigate the potential for Mn(2+), via its pro-oxidative properties, to activate production of pro-inflammatory cytokines/chemokines IL-1β, IL-6, IL-8, IFNγ, TNFα, and G-CSF by human monocyte-derived macrophages in vitro. For these studies, the cells were isolated from peripheral blood mononuclear leukocytes and matured to generate a population of large CD14/CD16 co-expressing cells.

Inhaled microparticles containing clofazimine are efficacious in treatment of experimental tuberculosis in mice.

Inhalable clofazimine-containing dry powder microparticles (CFM-DPI) and native clofazimine (CFM) were evaluated for activity against Mycobacterium tuberculosis in human monocyte-derived macrophage cultures and in mice infected with a low-dose aerosol. Both formulations resulted in 99% killing at 2.5 μg/ml in vitro.

Prevalence of Theileria equi and Babesia caballi infections in horses belonging to resource-poor farmers in the north-eastern Free State Province, South Africa.

The prevalence of Theileria equi and Babesia caballi infections in the north-eastern Free State Province of South Africa was determined by examination of thin and thick Giemsa-stained blood smears, IFAT and PCR. No parasites were detected by microscopy from any blood samples collected at five study sites, Qwaqwa, Kestell, Harrismith, Vrede and Warden. Of the tested serum samples, 28/29 (96.
