[Q]: HIV-1-infected and/or immune-activated microglia and macrophages are pivotal in the pathogenesis of HIV-1-associated neurocognitive disorders (HAND). Glutaminase, a metabolic enzyme that facilitates glutamate generation, is upregulated and may play a pathogenic role in HAND. Our previous studies have demonstrated that glutaminase is released to the extracellular fluid during HIV-1 infection and neuroinflammation. However, key molecular mechanisms that regulate glutaminase release remain unknown. Recent advances in understanding intercellular trafficking have identified microvesicles (MVs) as a novel means of shedding cellular contents. We posit that during HIV-1 infection and immune activation, microvesicles may mediate glutaminase release, generating excessive and neurotoxic levels of glutamate.', 'MVs isolated through differential centrifugation from cell-free supernatants of monocyte-derived macrophages (MDM) and BV2 microglia cell lines were first confirmed in electron microscopy and immunoblotting. As expected, we found elevated number of MVs, glutaminase immunoreactivities, as well as glutaminase enzyme activity in the supernatants of HIV-1 infected MDM and lipopolysaccharide (LPS)-activated microglia when compared with controls. The elevated glutaminase was blocked by GW4869, a neutral sphingomyelinase inhibitor known to inhibit MVs release, suggesting a critical role of MVs in mediating glutaminase release. More importantly, MVs from HIV-1-infected MDM and LPS-activated microglia induced significant neuronal injury in rat cortical neuron cultures. The MV neurotoxicity was blocked by a glutaminase inhibitor or GW4869, suggesting that the neurotoxic potential of HIV-1-infected MDM and LPS-activated microglia is dependent on the glutaminase-containing MVs.

[Q]: South Africa is undergoing epidemiological and nutrition transitions with associated increases in the incidence of overweight, obesity and diet-related chronic diseases. With the emergence of the nutrition transition in South Africa, there is an urgent need for interventions to prevent overweight and obesity in children and adolescents as risk factors for chronic diseases in adolescence may track throughout later life. This research explored the potential for faith-based organisations (FBOs) to be used as community organisations for overweight and obesity prevention interventions in adolescents by assessing the readiness of religious leaders to engage in such interventions.', 'Surveys and focus group discussions (FGDs) were conducted with 51 religious leaders in Johannesburg and Soweto. The Community Readiness Model (CRM) survey was chosen to determine the stage of readiness of this community regarding overweight and obesity prevention. Six different dimensions were assessed in the CRM (community efforts, knowledge of efforts, leadership, community climate, knowledge of the issue, resources). The surveys were scored according to the CRM protocol. The survey data were supplemented with findings from FGDs. Thematic analysis was used to analyse the FGDs.', 'The mean community readiness score was 2.570.76 which equates with the "denial/resistance stage". The mean readiness score for resources was the highest of all the dimensions (3.770.28), followed by knowledge of the issue (3.200.51). The lowest score was seen for community knowledge of efforts (1.771.50), followed by community climate (2.000.64). FGDs helped interpret the CRM scores. FGDs showed that religious leaders were enthusiastic and recognised that their role was not limited solely to spiritual guidance and mentoring, but also to physical well-being.

[Q]: Aberrant signal transducer and activator of transcription 3 (STAT-3) molecular signaling elicit hepatocellular carcinoma (HCC) in humans. Therefore, targeting STAT-3 is considered as an attractive option towards suppression of HCC in humans.', 'Our objective is to identify a potential small molecule inhibitor that can specifically target STAT-3 and suppress HCC.', 'In this study, we analyze a group of sesquiterpene lactone (STL) candidates that has been recently reported in preclinical trials against cancer by a unified computational and experimental approach.', 'Our virtual analysis of the STL candidates revealed Artesunate (ATS) as the best potential inhibitor of STAT-3 with comparable potency to specific inhibitor S3I-201. We also observed that ATS inhibited IL-6 driven STAT-3-DNA binding activity with comparable potency to S3I-201 in a cell free system. Furthermore ATS was observed to interfere with STAT-3 dimerization and suppression of both constitutive and IL-6 inducible STAT-3 in vitro. Nevertheless, we also observed that ATS modulated STAT-3 dependent targets (procaspase-3, Bcl-xl and survivin) favoring occurrence of apoptosis in vitro. Overall, the putative inhibition of STAT-3 by ATS suggested its capacity to interfere with STAT-3 dimerization by binding to the SH2 domain of STAT-3 monomer. It resulted in suppression of STAT-3 and also favored promotion of in vitro cells towards apoptosis. Consequently, ATS also exhibited selective cytotoxicity of cancer cells over normal cells in vitro.
