Effect of Ricinodendron heudelotii seed extract on the oxidative stress biomarkers of Diabetic albino rats
This study evaluated the potentials of the seed extract of Ricinodendron heudelotii on the oxidative stress biomarkers of diabetic albino rats of the wistar strain. Diabetes mellitus was induced via intraperitoneal administration of 160 mg/ kg bodyweight Alloxan monohydrate in normal saline and confirmed after 120 hours of blood glucose level above 300mg/dl. Blood samples were collected from the animals and analyzed for Malondialdehyde, Catalase, Reduced Glutathione, Glutathione-S-transferase, Glutathione peroxidase, and Superoxide dismutase activities as biomarkers of oxidative stress. The result revealed a significant decrease at P≤0.05 in blood glucose concentration of diabetic rats with increase in the seed extract concentration, Malondialdehyde (MDA) decreased significantly in the diabetic rats while Catalase increased significantly at P≤0.05 as the extract concentration increased. Variations in Glutathione-S-transferase, Glutathione Peroxidase, Superoxide dismutase and Reduced Glutathione in comparison with control was observed. The results therefore suggests that the aqueous seed extract of Ricinodendron heudelotii has the potency to reduce glucose level and act as antioxidants against oxidative stress, hence its use therapeutically.

Protein-protein interactions (PPIs) and protein complexes formed by interactions are the main accomplishers of various functions of cells. As an important component of biological networks, protein interaction plays an important role in determining life processes such as signal transduction in cells. Although the experimental methods for studying protein interactions are endless, there are still many shortcomings and gaps in the research on the interaction of precisely regulated protein molecules. LOV (Light Oxygen Voltage) is a light-sensitive protein domain originally discovered in the photo of plants for receiving blue light stimulation, transmitting signals, and causing a series of reactions in plants. The LOV domain belongs to a member of the PAS (Per-Arnt-Sim) superfamily and contains two subunits, LOV1 and LOV2. LOV2 is thought to cause a conformational change after receiving light stimulation, primarily responsible for activating the kinase domain. It plays an important role in intracellular signal transduction. In view of the light control and sensitivity of LOV2, which can be used as a research tool in protein interaction processes, the mechanism of action and structural advantages of signal transduction in LOV2 domain in protein interactions are reviewed.
Complexation of diclofenac sodium with hydroxy propyl betacyclodextrin improves its solubility and stability in ampoule solution which is determined by HPLC
Diclofenac sodium injection is widely used in medicine as antinflamatory and antirheumatic agent with a therapeutic value of 25 mg / ml. However, diclofenac sodium is poorly soluble which forms a problem in its manufacturing as an injection. The available commercial products of diclofenac sodium ampoules have used different types of solubilizing agents as benzyl alcohol which is an irritant in a concentration more than 3% while the other manufacturers used propylene glycol which has toxic impurities. In this present work, Diclofenac Sodium injection is prepared by using Hydroxy Propyl Beta Cyclodextrine ; a natural and safe excipient in formulation of ampoule solution which formed an inclusion complex compounds with Diclofenac Sodium ,render it very soluble and more stable.
