background exposure to the excessive levels of occupational noise is one of the principal harmful agents affecting the workers’ health. this study aimed to investigate the relationship between the occupational noise exposure and the hearing loss caused by working in small-scale service industries in the city of damavand, close to the metropolitan capital city of tehran, iran. methods this descr...

abstract background: hypertensive disorders in pregnancy are the main cause of maternal and fetal mortality; however, they have no definite effective treatment. the researchers aimed to study the effects of progressive muscular relaxation and breathing control technique on blood pressure (bp) during pregnancy. materials and methods: this three‑group clinical trial was conducted in mashhad healt...

modification of natural polymers like protein by graft co-polymerization is an important method to incorporate the desired properties into the backbone. soy protein concentrate (spc) was grafted with ethylmethacrylate (ema) using ascorbic acid /potassium persulphate as redox initiator system under pressure. different reaction parameters such as reaction time, reaction pressure, solvent amount, ...

Objective: The aim of this study was to investigate the effect of pre-treatment with curcumin on metabolic changes induced by two different pathophysiological mechanisms in rats (fructose diet and streptozotocin (STZ)-induced diabetes mellitus). Materials and Methods: Five groups with 10 rats per group were investigated: control group (healthy rats), fructose diet groups without any pre-treatme...

objective(s) this study aimed to investigate and to compare the effects of nifedipine and amlodipine, dihydropyridine (dhp) calcium channel blockers (ccbs) on perfusion pressure of isolated perfused rat kidney. materials and methods following the establishment of renal perfusion with a constant baseline pressure of 85-95 mmhg, the renal vasculature was constricted by phenylephrine (pe) injectio...

background: the cardiac effects simultaneously occurring during experimental hypertension and diabetes have rarely been investigated. this study aimed at examining the effects of short-term renovascular hypertension and type 2 diabetes on cardiac functions. methods: five groups (7 each) of male sprague-dawley rats, including a control group, a diabetes (induced by streptozocin and nicotinamide)...

the objective of this study was to determine the chronology of changes in blood pressure in renalhypertension induced by solid plexiglass clips in rats. saw blades with the thickness of 0.21-0.22 mm wereused to make clips sized 4 × 2 × 2 mm from a piece of 2-mm thick plexiglass. rats were subjected to shamoperation or left renal arterial clipping, and 1, 2, 3 and 4 weeks later blood pressure, a...
