Anti-Inflammatory And Antioxidant Effects Of Sea Urchin Spine Extract, Dina Magdy El Gamal
Anti-Inflammatory And Antioxidant Effects Of Sea Urchin Spine Extract, Dina Magdy El Gamal
The Undergraduate Research Journal
Diadema savignyi spine extract in an experimental setup using L929 cell line in vitro. The cell metabolic activity of L929 cells is tested through an MTT assay. The sea urchin spine extract is applied to the cells in two concentrations: 100 μg/ml (136% viability) and 200 μg/ml (95% viability). The bioactive components of the sea urchin spine are identified via GC-MS, and the antioxidant and anti-inflammatory activities are evaluated using catalase assay (CAT), glutathione (GSH), and nitric oxide (NO) tests. Results show that the GC-MS identified bioactive components including the anti-inflammatory and anti-irritant bisabolol oxide and the pro-inflammatory oleic acid. …

The article describes the simulation of the temperature field in a wide range of structural and operational parameters of the drying process. A qualitatively new representation of the temperature field profile in the chamber is revealed. As a result of the experiments, criteria were found for the unevenness of the temperature profiles on the pallets of the dispersion of the temperature of the material and the slope of the approximating line at fixed values of the average temperature of the substance. In the course of the work, an interrelation between the criteria of unevenness was revealed, which is clearly manifested …

Excerpts in Pharmacy Research Journal
The proprotein convertase subtilisin/kexin type 9 (PCSK9) gene and gain-of-function mutations were first described in 2003. The gain-of-function mutations observed were associated with low-density lipoprotein-cholesterol (LDL-C) levels in the 400’s, in addition to premature cardiovascular disease. Subsequent loss-of-function experiments conducted in mice demonstrated marked reductions in plasma cholesterol levels in the absence of PCSK9. Physiologically, PCSK9 serves as a chaperone protein and functions to reduce low-density lipoprotein (LDL) receptor recycling; consequently, less LDL-C is removed from circulation and serum lipid concentrations become elevated. Inhibition of PCSK9 prevents LDL receptor degradation and preserves receptor recycling to the hepatocyte surface; this in …
