brown tumors may occur secondary to hyperparathyroidism in patients with chronic renal failure (ckd). they are increasingly rare because hyperparathyroidism in now diagnosed and treated at an early stage. we report 67-year-old man who had been on hemodialysis for crf for over 3 years, who presented with back pain over the thoracolumbar junction from 2 years ago and because of pain he could not ...

this research was performed to determine the efficiency effect of sedimentary environment of kerman city area on soil structure bycomparing natural and reconstituted consolidation curves. in this regard, four different criteria such as sensitivity strength, stresssensitivity, schmertman criteria and the result of the uniaxial compression test were used. the base of these criteria is to compare ...

in the hot compression test friction has a detrimental influence on the flow stress through the process and therefore, correcting the deformation curve for real behavior is very important for both researchers and engineers. in this study, a series of compression tests were simulated using abaqus software. in this study, it has been employed the taguchi method to design experiments by the factor...

conclusions large-scale studies on the healthy black african population could assess the relationship between diastolic dyssynchrony and changes in myocardial performance related to racial differences. results the frequency of some dyssynchrony markers was similar to that of other studies. the difference between maximal time-to-peak systolic velocity and minimal time-to-peak systolic velocity w...

Fatigue resistance of nitinol stents implanted in femoropopliteal arteries is a critical issue because their harsh biomechanical environment. Limb flexions due to daily walk expose the and, subsequently, large cyclic deformations, which may lead fatigue failure smart self-expandable stents. For first time, this paper utilised up-to-date measurements walk-induced motion human artery investigate ...

safranal, the main component of crocus sativus essential oil, exhibits different pharmacological activities. in this study, the effects of safranal, on blood pressure of normotensive and desoxycorticosterone acetate (doca) - salt induced hypertensive rats in chronic administration were investigated. three doses of safranal (1, 2 and 4 mg/kg/day) and spironolactone (50 mg/kg/day) were administra...

vitamin d deficiency has been proposed as an associating factor with increased blood pressure. we studied the relationship between serum vitamin d and blood pressure in a large representative sample of iranian population. in this cross-sectional study, based on the data of 2508 adults (aged between 20 and 70 years) from the iran multicenter osteoporosis study (imos), the association between ser...

background: hypertension is fast emerging as a major health problem amongst all school adolescents, particularly in urban areas. regular screening of the students for this is required for preventing the emergence of complications later in life. therefore,the present study was undertaken with the objective to determine the prevalence of hypertension amongst urban school adolescents and its corre...

Abstract Background Pseudoaneurysm of the mitral-aortic intervalvular fibrosa (P-MAIVF) is a rare complication infective endocarditis and aortic valve replacement. Ruptured P-MAIVF angina due to compression coronary arteries are severe complications this condition. Case presentation We report case that was diagnosed accidentally during routine checkup. The patient asymptomatic; however, she had...
