background: patients with functional gastrointestinal disorders (fgids) may use specific coping strategies. we intend to provide a mediating role of the relationship between pain (intensity and acceptance), cognitive emotion regulation strategies, and negative emotions in patients with fgids. materials and methods: participants were 176 inpatients, all experiencing significant fgids symptomatol...

liver functional tests due to inflammatory process which induced by cholecystitis might changed and some clinicians suggested that these changes might help us to stone prediction in common bile ducts and decrease hazards of performing ercp and other invasive procedures. present study was performed for assessment of role of liver functional test in diagnosis of common bile duct stone in patients...

background: patients with schizophrenia can experience a deteriorated performance in many of the skills needed in daily life, the workplace, the family circle, or in social interactions.objective: this definitive study used comparison to evaluate the functionality, treatment compliance to therapy, and styles of coping with stress of schizophrenic patients who work and are members of an associat...

background: intracranial lesions of the pituitary gland are common pituitary adenomas, accounting for 6-10% of all symptomatic intracranial tumors. in this retrospective study, the clinicopathologic features and survival rate of pituitary adenomas were evaluated. methods: the present retrospective study was conducted on 83 patients with pituitary adenomas, referring to radiation oncology depart...

background and objectives: recently, due to the interest of healthy lifestyle demand for research on novel methods of increasing the shelf-life of food products without the necessity of using preservatives has extended rapidly in the world. ability of nanoemulsions to improve global food quality has attracted great attention in food preservation. this is as a result of a number of attributes pe...

in recent years, several oconjugation protocols have been developed to improve the functional properties of the enzyme lysozyme. in this study, the optimum conditions of lysozyme – oxidized inulin conjugation and functional properties of the modified lysozyme were investigated. initially, inulin (mw about 25 kda) was oxidized by periodate to provide the reactive carbonyl groups  to attach to am...

in  this paper, we investigate the generalizedhyers-ulam-rassias stability for the quartic, cubic and additivefunctional equation$$f(x+ky)+f(x-ky)=k^2f(x+y)+k^2f(x-y)+(k^2-1)[k^2f(y)+k^2f(-y)-2f(x)]$$ ($k in mathbb{z}-{0,pm1}$) in $p-$banach spaces.

here, a predator-prey model with hassell-varley type functional responses is studied. some sufficient conditions are obtained for the permanence and global asymptotic stability of the system by using comparison theorem and constructing a suitable lyapunov functional. moreover, an example is illustrated to verify the results by simulation.

nanocomposite composed of organoclay(cloisite 20a-c20a) and poly lactic acid (pla) was prepared by solvent casting method. physical, mechanical, thermal, barrier and microstructure properties of the composite were studied. x-ray diffraction (xrd) patterns and scanning electron microscopy (sem) images revealed that the diffraction peak of nanoclay shifted to lower angles and the d-spacing betwee...

aim and background: the purpose of this study was to compare patients with functional gastrointestinal disorders (fgid) and normal persons in terms of alexithymia, severity of gastrointestinal symptoms, and demographic variables. methods and materials: this causal-comparative research included 129 fgid patients who were referred to a psychosomatic disorders clinic in isfahan, iran. a matched gr...
