داده های نوری سیستم ls del که از نوع w uma می باشد، در صافیهای ubv مورد تجزیه و تحلیل قرار گرفته است. برای حل این سیستم از برنامه ویلسون 2003 استفاده شده است. در برنامه ون هم با در نظر گرفتن الگوی لگاریتمی کلینگ لسمیت و سوبیسکی برای پیدا کردن ضرایب تاریکی لبه استفاده شده است. نتایج حاکی از آن است که سیستم تماسی بوده و هر دو مؤلفه حد روچ خود را پر کرده اند. رده طیفی مؤلفه اصلی و همدم این سیستم ب...
In this paper we have analyzed the photometric data of LS DEL eclipsing binary system, which was W UMa one, in UBV filters. To solve light curves we use Wilson program 2003. We have found the darkening coefficients of the side by using Klinglesmith and Sobieski (1970) Algorithm in Van Hamme program. The results show that the system was a contacted one, and both primary and secondary components ...
Rheumatoid arthritis (RA) significantly affects quality of life. We recently cloned synoviolin, a RING-type E3 ubiquitin ligase implicated in the endoplasmic reticulum-associated degradation (ERAD) pathway. Synoviolin is highly expressed in rheumatoid synovial cells and may be involved in the pathogenesis of RA. Inhibition of synoviolin activity i...
Background: MDM2 (Murine Double Minute2) is an oncoprotein that inhibits the P53 activity. Overexpression of MDM2 gene has been reported in several human tumors. In the present study, we aimed to evaluate the impact of 40-bp insertion/deletion (ins/del) polymorphism on the promoter of MDM2 and susceptibility to breast cancer in a sample of Iranian population. Methods: This case-control study wa...

Explanations for why sympatric ruminant species select diets composed of different plant species or plant parts have been controversial. Our explanation is based on learning from foraging consequences, which includes the influences that morphology, physiology, and experience have on diet selection. We conducted a trial with cattle (Bos taurus), sheep (Ovis arias), and goats (Capra hircus) and l...
Negli ultimi cent’anni, qua e là nella comunità degli studiosi internazionali, in tanti hanno dedicato studi approfonditi alle varie tematiche del capolavoro manzoniano ovvero I Promessi Sposi. A maggior ragione, l’opera citata è stata sempre un punto cruciale della letteratura italiana. La lettura critica svolta sul sudetto romanzo da Norberto Cacciaglia meriterebbe una pausa rifflettiva in pi...
compelling evidence suggests that the oxidative stress plays a key role in the pathophysiology of cardiovascular disease (cvd). superoxide dismutase (sod) enzymes play a major role in detoxification of reactive oxygen species and protection against oxidative stress. we examined the possible association between a 50-bp insertion/deletion in the sod1 promoter 1684-bp upstream of the sod1 atg with...
Objective Indiscriminate use of synthetic pyrethroid insecticides, Cypermethrin (Cyp) and Deltamethrin (Del) have been reported to cause system toxicity in mammals including humans. The dietary antioxidants protects tissues and organs against insecticides/xenobiotic induced damage. In present study, we evaluated the effect of exposure of Cyp and Del and possible protective roles of curcumin and...
