Bio-ethical issues of research in Sub-Saharan Africa.

This paper examines bioethical considerations of research conducted in Sub-Saharan Africa (SSA), where a notable scarcity persists in literature addressing region-specific bioethical issues. Although bioethics-related activities have encountered challenges surpassing existing protocol safeguards, emerging evidence demonstrates growing recognition of integrated scientific and ethical principles within African medical research. Maintaining research continuity in resource-limited settings necessitates bridging critical gaps between informed consent procedures and participants' actual understanding.

Activation of ventral tegmental area vesicular GABA transporter (Vgat) neurons alleviates social defeat stress-induced anxiety in APP/PS1 mice.

Introduction: Alzheimer's disease (AD) is a progressive neurodegenerative disease that results in cognitive impairment and is often accompanied by anxiety. In this study, we investigated whether the activation of VTA neurons could reduce anxiety in APP/PS1 mice. We hypothesized that acute social defeat stress (SDS) would lead to anxiety in APP/PS1 mice, and that the activation of VTA neurons would alleviate this anxiety.
