Presence of Bacillus thuringiensis (Bt) gene in cereals and cereal-based products in local markets and supermarkets of Yaoundé, Cameroon

The use and importation of genetically modified (GM) crops and products derived from these crops are regulated by national and international policies, which unfortunately are often not properly implemented in some countries. Given the ongoing globalization of trade and increasing availability of GM plant products, countries like Cameroon with a weak system to regulate the importation of these products face the threat of...

Febuxostat in patients with hyperuricemia and severe chronic kidney disease

Febuxostat is a non-purine, selective inhibitor of both isoforms of xanthine oxido-reductase (XOR). Its pharmacokinetics is not dependent on renal clearance, and it may be advantageous in patients with chronic kidney disease (CKD). Although febuxostat is effective in patients with mild-to-moderate CKD, its efficacy and safety in patients with severe CKD remain unclear. This retrospective study included patients with an...

Gamma oryzanol loaded microspheres with improved bioavailability

Gamma oryzanol is a phytosterol that is extracted from rice bran oil. It is an antioxidant that possesses a curative effect for many diseases. Gamma oryzanol is a water insoluble compound supporting the idea that it has a low bioavailability due to low intestinal absorption. In this study, γ-oryzanol was loaded in biodegradable microspheres. Intestinal absorption of γ-oryzanol from microspheres was compared...
