introduction: free radicals are molecules or atoms with single electron that results in reactions thus causing severe damages to the body’s macromolecules. by preventing the formation of free radicals, repairing damages caused by radical’s activities, increasing the excretion of the damaged molecules and minimizing the cellular mutation, the antioxidant defense system contrasts the damages caus...
background: celiac disease (cd), as an autoimmune disease has initiated since ingestion of food containing gluten. constant intolerance to gluten causes damages of the small intestinal mucosa. one reason of mal-absorption in children and infants is cd. additionally, about 75% of newly identified patients with cd have low bone mineral density (bmd). many factors have role in metabolic bone disea...
objective: this study compared the tension-free vaginal tape (tvt) and transobturator tape (tot) procedures for surgical treatment of stress urinary incontinence in women. materials and methods: this prospective non randomized clinical trial was conducted in vali-e-asr hospital from march 2001 to march 2005. a total of 71 patients with clinical and urodynamic diagnosis of stress urinary inconti...
background: to introduce our experience of using the free neurovascular flap from great and second toe. methods: thirteen patients (fifteen fingers) sought surgical treatment for soft tissue defects of the hand at our medical institutin between march 2006 and september 2009. in two patients, fibular side skin-nail flaps of great toe were applied to cover the dorsal defect of distal thumb. i...
local perforator flaps have evolved over the time to provide complete and stable coverage of soft tissue defects. technical advances and experience with the perforator flaps have allowed the harvest of local perforator flaps in a free style manner by offering greater freedom in flap selection. we have proposed a technical modification in the harvest of a perforator flap by relo-cating the perfo...
background & aim: medicinal plants can be a good replacement for common cancer treatment including chemotherapy, radiation therapy and surgery because they don’t have many side effects. the aim of this study was to investigate the effect of temperature on the free radical scavenging in the presence of medicinal plants. experimental: for determination of free radical scavenging activity was...
background: knowledge of existing situation in each region plays great role in order to prevent oral and dental diseases in people. meanwhile, dmft index is one of the best epidemiological indices in dentistry representing oral hygiene situation in society. so, this study was conducted in order to evaluate dmft index in 12- years-old students of zarand city at 2011. methods: this descriptive st...
conclusions it seems that fast examination for intra-abdominal fluid in blunt trauma patients can predict intra-abdominal injuries with very high sensitivity and specificity. using the scoring system can more accurately determine the probability of the presence of abdominal injuries with a cut-off point of three. results the mean age of the patients was 29.6 ± 18.3 years and fast was positive i...
سینتیک تخریب حرارتی خانواده ای ازپلیمرهای گرما سخت (پلی آمیدها) با استفاده از تکنیک tga ، در سه سرعت گرمادهی (0c min-1 20 و15 ،5/7) در اتمسفر نیتروژن بررسی شده است. روش های isoconversional (model – free) )از قبیل روش های فلاین، وال و ازاوا (fwo)، کیسینجر، آکاهیرا و سانوز(kas) و تانگ (tang) (و model – fitting (روش کوتس و ردفرن ((cr)استفاده شده اند تا سه تایی سینتیکی یعنی انرژی فعالسازی، فاکتو...
در این پژوهش نانو ذرات هیبریدی نانو لوله کربنی- اکسید روی سنتز و شناسایی شده¬است و نتایج آنالیز دستگاهی tem, sem و ft-ir تشکیل نانو ذره هیبریدی را تایید می¬نماید. اثر هیبرید سازی نانو لوله کربنی با اکسید¬ روی سرعت تخریب حرارتی یک ترموست بر پایه dgeba مورد بررسی قرار گرفت. مطالعات مقایسه¬ای نشان داد که سرعت تخریب با هیبرید سازی نانو ذرات کاهش می¬یابد و از روش زیر تبعیت می¬کند. rpure dgeba > r m...
