A deletion of ∼20 amino acids in the stalk of neuraminidase is frequently observed upon transmission of influenza A viruses from waterfowl to domestic poultry. A pair of recombinant H7N1 viruses bearing either a short- or long-stalk neuraminidase was genetically engineered. Inoculation of the long-stalk-neuraminidase virus resulted in a higher cloacal excretion in ducks and led conversely to lo...
برنامه ریزی خطی(lp) یک گروه مهم از مسائل بهینه سازی است که در اقتصاد،پژوهش های عملیاتی،مهندسی و حوزه های دیگر علمی مورد استفاده قرار می گیرد.در سال 1985 تانک و هاپفیلد مقاله ای را منتشر کردند و یک روش جدید برای حل مسائل برنامه ریزی خطی با استفاده از شبکه های عصبی بازگشتی ارائه دادند.مدل مذکور پاسخ های یک مسأله ی lp را خیلی سریع به دست می آورد.در سابل 1987 کندی و چوا و بعدها مآ و شنبلت مدل های ب...
Sphingosine 1-phosphate (S1P) exerts diverse physiological actions by activating its cognate G protein-coupled receptors. Five S1P receptors have been identified in mammals: LP(B1)/EDG-1, LP(B2)/H218/AGR16/EDG-5, LP(B3)/EDG-3, LP(B4)/NRG-1/EDG-8, and LP(C1)/EDG-6. One of these receptors, LP(B1), has recently been shown to be essential for mouse embryonic development. Here we disrupted the lp(B3...
Lichen Planus actinicus (LP actinicus) is a variant of lichen planus often confined to individuals in tropical and subtropical regions. The lesions involve sun-exposed areas and are characterized by well-defined nummular patches which have a deeply hyperpigmented centre surrounded by a hypopigmented zone. It mainly involves teenagers with an Asian racial profile. We report a rare case of a 10 y...
Background: Unstable angina and myocardial infarction are developed due to atherosclerosis of coronary arteries. At present, cholestrol, triglyceride, and lipoproteins are the most common risk factors of death. The purpose of this study was to assess the serum levels of LP (a), LDL-C, VLDL-C, HDL-C in cases of unstable angina and myocardial infarction.Methods: This study was conducted to compar...
So far, we have seen many algorithms based on linear program (LP) relaxations, typically involving rounding a given fractional LP solution to an integral solution of approximately the same objective value. In this lecture, we will look at another approach to LP relaxations, in which we will construct a feasible integral solution to the LP from scratch, using a related LP to guide our decisions....
Apolipoprotein B is a stronger predictor of myocardial infarction than LDL cholesterol, and it is inversely related to physical activity and modifiable with exercise training. As such, apolipoprotein measures may be of particular relevance for subjects with PAD and claudication. We compared plasma apolipoprotein profiles in 29 subjects with peripheral artery disease (PAD) and intermittent claud...
Introduction: Lipoprotein (a) is a particle rich in cholesterol in human plasma and it is known as an independent risk factor for coronary artery disease. In addition to genetic background, other factors such as diabetes affect the plasma concentration of this lipoprotein as a risk factor. The aim of this study was evaluation and comparison of plasma concentration of Lp(a) in type II diabetics ...
زمینه: لیپوپروتئین- آ [lp(a)] یک ذره غنی از کلسترول در پلاسمای انسان با خواص پلاک زایی و لخته زایی است. غلظت پلاسمایی lp(a) به طور عمده به زمینه ژنتیکی و کم تر به عوامل دیگر بستگی دارد. در مورد میزان طبیعی و تغییرات زیست شناختی این لیپوپروتئین در بین ایرانیان اطلاعات ناچیزی وجود دارد. هدف: مطالعه به منظور تعیین تغییرات زیست شناختی lp(a) و سایر چربی های سرم در دانشجویان در یک دوره شش ماهه انجام ...
introduction: sometimes physicians need to assess some markers on selected children's cerebrospinal fluid specimen according to lumbar puncture (lp). although immediate diagnosis and treatment especially for meningitis is necessary, but just at this moment, due to some incorrect believe in society, some parents may not allow physician to do lp. the reality is that most of these people, i...
