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...

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, ...

the aim of present paper is to provide mathematical modelling for the two-dimensional mhd flow with induced magnetic field. the flaws in the already existing equations have been pointed out. the results of low magnetic reynolds number approximation are recovered as a special case from the developed equations. as an example, the peristaltic flow for a couple stress fluid in a channel is consider...

a 78-year-old woman with burn-induced cervico-mento-sternal scar contracture was scheduled for laparoscopic cholecystectomy. during inhalational induction of sevoflurane, her airway patency deteriorated. the right lateral position and assist ventilation using a breathing bag dramatically improved her airway patency.

background and objectives: acantholimon bracteatum (girard) boiss (plumbaginaceae) is used in variety of diseases including hepatic ailments in the west regions of iran. in the present study, the hepatoprotective effect of the methanol extract (me) of a. bracteatum on formaldehyde (fa) induced liver injury has been investigated in adult male mice. methods: fifty six adult male mice were divided...

background outer hair cells' (ohcs') dysfunctions as the extent of temporary and permanent threshold shifts (tts and pts) and cochlear damage were assessed in rabbits exposed to continuous noise methods twelve new zealand white rabbits were studied in noise (n) (n=6; exposed to continuous noise; 95 db spl, 500-8000 hz for 8 h per day during 5 consecutive days) and control (c) (n=6; no...

introduction: hearing loss is one of the most common occupational diseases. in most workplaces, workers are exposed to noise and solvents simultaneously, so the potential risk of hearing loss due to solvents may be attributed to noise.  in this study we aimed to assess the effect of exposure to mixed aromatic solvents on hearing in the absence of exposure to hazardous noise.   materials and met...

objectives: this study describes a single subject design (aba) that shows the effective use of constraint induced movement therapy in improvement of quality and performance of in-hand manipulation skills for a 10 year old boy and a 9 years old girl with hemiplegic cerebral palsy, as dickerson (2007) showed it in arm movement and function. methods: to determine the effectiveness of cimt by the u...

background: noise-induced hearing loss (nihl) is one of the most common occupational diseases and the second most common cause of workers' claims for occupational injuries. objective: due to high prevalence of nihl and several reports of improper use of hearing protective devices (hpds), we conducted this study to compare the effect of face-to-face training in effective use of earplugs with app...

background: noise-induced hearing loss (nihl) is one of the most common occupational illnesses. most of the studies on nihl were conducted at high noise levels that people are rarely exposed to but in industries. the function of the outer hair cells (ohcs) is impaired after exposure to industrial noise. distortion product otoacoustic emissions (dpoaes) are useful in examination of noise-induced...
