Article Abstract
Mitochondrial bioenergetics in females and males is different. However, whether mitochondria from male and female brains display differences in enzymes of oxidative phosphorylation remains unknown. Therefore, we characterized mitochondrial complexes from the brains of male and female macaques (Macaca mulatta). Cerebral tissue from male macaques exhibits elevated content and activity of mitochondrial complex I (NADH:ubiquinone oxidoreductase) and higher activity of complex II (succinate dehydrogenase) compared to females. No significant differences between sexes were found in the content of α-ketoglutarate dehydrogenase or in the activities of cytochrome c oxidase and FF ATPase. Our results underscore the need for further investigations to elucidate sex-related mitochondrial differences in humans.

Background: Digital media frequently contains positive portrayals of alcohol content, which has been shown to be associated with alcohol-related cognitions and behaviors. Because youth are heavy media consumers and have access to unsupervised, repeat viewing of media content on their personal mobile devices, it is critical to understand the frequency of encountering alcohol content in adolescents' daily lives and how adolescents engage with the content.
Objective: This paper outlines the study protocol for examining adolescents' exposure to alcohol-related content in digital media within their natural environments.

Background: Various media are used to enhance public understanding about diseases. While mobile health apps are widely used, there is little proof for using such apps to raise awareness of skin diseases.
Objective: We intend to develop an app, called DEDIKASI-app, to raise awareness of skin diseases, including leprosy.
