background: diabetes mellitus is a common metabolic disorder worldwide. it imposes excessive psychological stress on patients which negatively affect the course of the disease. the brain-behavioral systems have a role in dealing with stressful events such as chronic disorders. objective: comparison the brain-behavioral systems and psychological distress in diabetic patients and non-diabetics. m...

Man’s largely uncontrolled use and exploitation of the natural environment and the ever increasing needs of an – arguably overpopulated world have lead to a situation in which only scientific assessment, planning and management can provide some measure of sustainability of the use of natural resources. Especially in the developing world with its limited access to technology, funds and expertise...

there are many evidences that human serum paraoxonase activity modifies plasma lipid profile and paraoxonase has an antiatherogenic property. non-selective beta-blockers affect plasma lipid profile too, but they have atherogenic property when patients take these drugs in long term. in this study the effect of propranolol, a non-selective beta-blocker, on paraoxonase activity was investigated. l...

the corrosion inhibition characteristics of two synthesized schiff bases, namely n, n´-bis(2-hydroxy-6-nitrobenzaldehyde) benzidine  and n, n´-bis(salysylaldehyde) benzidine, on the mild steel corrosion in 2.0 m hydrochloric acid have been investigated by weight loss, potentiodynamic polarization and electrochemical impedance spectroscopy techniques. these studies were carried out at different ...

a fundamental study of scale formation of calcium carbonate (caco3) for producing oil wells hasbeen carried out. this article presents the study of the prediction of salt deposition in two differentsynthetic formation waters and investigates the effects of temperature and pressure on calciumcarbonate precipitation. the dependence of the induction period of the precipitation of calciumcarbonate ...

vanillin offers interesting possibilities for corrosion inhibition because of its safe use and highsolubility in water. the effect of vanillin on the corrosion inhibition of aisi 304 stainless steel in0.5m h2so4 solution has been studied using potentiodynamic polarization and electrochemicalimpedance spectroscopy (eis). furthermore, this paper demonstrates that the electrochemical noise(en) tec...

a dot immunobinding assay ( dia) was used for a quantitative and qualitative assay of rubella antibody. purified antigen and conjugated anti-human immunoglobulin (rahlg) were prepared. nitrocellulose paper dotted with the antigen was added to serially diluted sera or blood samples. the reacting antibodies were visualized by a peroxidase system. development of a colored insoluble substrate was t...

derivatives of phenyl-keto butenoic acids have been reported to be inhibitors of pyruvate decarboxylase, (pdc). the inhibition of transketolase, a thiamine requiring enzyme such as pdf, by meta nitrophenyl derivative of 2-oxo-3-butenoic acid (mnpb) is reported here. these studies indicate that the inhibitor binds to the enzyme at the active site. a two-step inhibition was observed, first the in...
