The relationship between social media use, social media types, and job performance amongst faculty in Kenya private universities.

There has been an increased interest in social media that is attributed to the rapid growth in the media use. Covid-19 has also significantly heightened the interest, with organisations relying more on social media. In particular, universities have reduced their dependency on face-to-face teaching and are relying more on social media for teaching, research, and service.

Hydrogen peroxide inhibition of bicupin oxalate oxidase.

Oxalate oxidase is a manganese containing enzyme that catalyzes the oxidation of oxalate to carbon dioxide in a reaction that is coupled with the reduction of oxygen to hydrogen peroxide. Oxalate oxidase from Ceriporiopsis subvermispora (CsOxOx) is the first fungal and bicupin enzyme identified that catalyzes this reaction. Potential applications of oxalate oxidase for use in pancreatic cancer treatment, to prevent scaling in paper pulping, and in biofuel cells have highlighted the need to understand the extent of the hydrogen peroxide inhibition of the CsOxOx catalyzed oxidation of oxalate.

Nicotinamide adenine dinucleotide biosynthesis promotes liver regeneration.

Unlabelled: The regenerative capacity of the liver is essential for recovery from surgical resection or injuries induced by trauma or toxins. During liver regeneration, the concentration of nicotinamide adenine dinucleotide (NAD) falls, at least in part due to metabolic competition for precursors. To test whether NAD availability restricts the rate of liver regeneration, we supplied nicotinamide riboside (NR), an NAD precursor, in the drinking water of mice subjected to partial hepatectomy.
