گلوتاتیون s-ترانسفراز خانواده خیلی بزرگی از آنزیم¬های سم¬زدایی بوده و نقش حیاتی را در فاز دوم بیوترانسفورماسیون بسیاری از زنوبیوتیک ها، داروها و عوامل سرطان¬زا ایفاء می¬کنند. چندشکلی¬های ژنتیکی این آنزیم¬ها ممکن است استعداد افراد به ابتلاء به بیماری¬های ناشی از اثرات مخرب متابولیت¬های اکسیداتیو را، تحت تاثیر قرار دهد. مطالعات گذشته در میان جمعیت¬های مختلف نشان داده¬اند که فراوانی حذف شدگی¬های ه...

Background and purpose: Glutathion S-transferase (GSTs) are a family of detoxification phase II enzymes that catalyze the conjugation of carcinogenic and cytotoxic componds with glutathion. GSTs are polymorphic and deletion of GSTM1 and GSTT1 polymorphism is caused by lack of enzyme production that lead to loss of antioxidant activity. In this study, we examined the frequency of GSTM1 and G...

Local deterministic string-to-string transductions are generalizations of morphisms on free monoids. Learning local transductions reduces to inference of monoid morphisms. However, learning a restricted class of morphisms, the so-called fine morphisms, is an intractable problem, because the decision version of the empirical risk minimization problem contains an NP-complete subproblem.

Background Endometriosis is one of the most commonly encountered benign problems in gynaecology. It is frequently associated with chronic pelvic pain, dysmenorrhoea, menorrhagia and dyspareunia, which lead to infertility. We determined the possible association between CYP1A1 MspI and GSTM1 null polymorphism in the pathogenesis of endometriosis. MaterialsAndMethods Ninety seven cases of endometr...

With each of the classical tree–like forcings adjoining a new real, one can associate a σ– ideal on the reals in a natural way. For example, the ideal of Marczewski null sets s corresponds to Sacks forcing S, while the ideal of nowhere Ramsey sets r corresponds to Mathias forcing R. We show (in ZFC) that none of these ideals is included in any of the others. We also discuss Mycielski’s ideal P2...

Doubly stochastic matrices play a fundamental role in the theory of majorization. Birkhoff's theorem explains the relation between $ntimes n$ doubly stochastic matrices and permutations. In this paper, we first introduce double-null  operators and we will find some important properties of them. Then with the help of double-null operators, we investigate Birkhoff's theorem for descreate $l^p$ sp...
