Mitochondrial DNA abnormalities provide mechanistic insight and predict reactive oxygen species-stimulating drug efficacy

Associations between mitochondrial genetic abnormalities (variations and copy number, i.e. mtDNAcn, change) and elevated ROS have been reported in cancer compared to normal cells. Since excessive levels of ROS can trigger apoptosis, treating cancer cells with ROS-stimulating agents may enhance their death. This study aimed to investigate the link between baseline ROS levels and mitochondrial genetic abnormalities, and how mtDNA abnormalities might be used to predict cancer cells’ response to ROS-stimulating therapy

Communication and learning: Social networking platforms for higher education

This study explored the use of social networks specifically for general communication and learning in higher education. The types of social networks used by most students in higher education were identified before examining the difficulties faced by these students in handling social networks. Quantitative and qualitative data were gathered through survey distribution to several faculties. The results indicate the use of WhatsApp as the preferred application by students. In general, the major difficulties faced by these students in using social networks were misunderstanding and a lack of internet connection. Most suggestions for future social network features were for the design of an application which offers ease of use for general communication and learning purpose which has a high storage capacity, links to an educational portal and comes with a good internet connection service. In summary, WhatsApp is currently a priority for communication among these students and is, therefore, a preferred platform for the development of effective learning applications
