COVID-19 Outbreak in Africa: Lessons and Insights from the West African Ebola Virus Disease Epidemics

Over the years, the African continent has had to battle several outbreaks of infectious diseases in different countries. Some of the most deadly were the Ebola virus disease (EVD) outbreaks that occurred in West Africa between 2014 and 2016 affecting Guinea, Liberia, and Sierra Leone and, more recently, from 2018 to 2020 in the Democratic Republic of Congo (DRC). In the era of the COVID-19 pand...

Nanotechnology in dentistry: prevention, diagnosis, and therapy

Nanotechnology has rapidly expanded into all areas of science; it offers significant alternative ways to solve scientific and medical questions and problems. In dentistry, nanotechnology has been exploited in the development of restorative materials with some significant success. This review discusses nanointerfaces that could compromise the longevity of dental restorations, and how nanotechnol...

Significance of exosomes in COVID-19 pathogenesis and therapy

Exosomes are lipid bilayer-enclosed nano-sized vesicles, which carry various biomolecules including proteins, lipids, and microRNAs. SARS-CoV-2-loaded exosomes can be entered into the susceptible host cells, and transported viral components which are associated with viral particles intercellular transmission and spread of infection. Over-stimulation of the immune system followed by excessive pr...
