Objective(s): Protein kinase C (PKCα) is involved in modulating articular chondrocytes apoptosis induced by nitric oxide (NO). Hyaluronic acid (HA) inhibits nitric oxide-induced apoptosis of articular chondrocytes by protecting PKCα, but the mechanism remains unclear. The present study was performed to investigate the effects and mechanisms of PKCα regulate protective effect of hya...

Pure borax and various boron compounds are produced from the solutions in which tincal is dissolved with various reagents. Economically important boron compounds such as boric acid, borax, boric oxide, and refined hydrated sodium borates and perborates are produced from boron-containing ores. The production of boric acid by using nitric acid from tincal is more advantageous because it evalu...

N,N-diethylethanaminium-2-(sulfooxy) ethyl sulfate was synthesized and used as  an efficient, green, and recyclable catalyst and solvent for the nitration of aromatic compounds by nitric acid at 80oC

Maghemite (γ-Fe2O3) nanoparticles have been synthesized using a chemical coprecipitation method at different nitric acid concentrations as an oxidizing agent. Characterization of all samples performed by several techniques including X-ray diffraction (XRD), transmission electron microscopy (TEM), alternating gradient magnetometry (AGM), thermogravimetric analysis (TGA), dynamic light scattering...

Nitric oxide and sialic acid variables are indicators of the acute phase response. This study was planned to investigate the relationship between the level of serum nitric oxide and sialic acid in type 2 diabetes with and without nephropathy. Fasting venous blood samples were taken from 90 subjects of which 30 were of type 2 diabetic patients with nephropathy (group I), 30 type 2 diabetes witho...

Aim: The aim of the study is to evaluate the efficacy of different decalcifying agent used to decalcify bone. Bone is the strongest part in the human. Two types of bones are seen cancellous bone and compact bone. Demonstration of bone is quite difficult than any other tissues. To obtain satisfactory paraffin or celloidin of bone inorganic calcium must be removed from the organic collagen matrix...

this study was designed to explore the protective effects of ascorbic acid and water extract of spirulina platensis (blue green algae) on methotrexate-induced lipid peroxidation using goat liver as the lipid source. this in vitro evaluation was done by measuring the malondialdehyde, 4-hydroxy-2-nonenal, reduced glutathione and nitric oxide content of tissue homogenates. the study reveals the li...
