BACKGROUND AND OBJECTIVES Thirty to 50% of all COPD patients experience tissue wasting that may be caused by hypermetabolism, but the cause of the perturbed metabolic state is unclear. We hypothesized that the elevated O2 cost of ventilation (O2 COV) may be a contributing factor. All of the data are presented as means (+/-SEM). Ten hypoxemic (a PaO2 of 54+/-3 mm Hg) stable COPD patients (an FEV...
BACKGROUND Middle East respiratory syndrome coronavirus (MERS-CoV) causes severe lower respiratory tract infection in people. Previous studies suggested dromedary camels were a reservoir for this virus. We tested for the presence of MERS-CoV in dromedary camels from a farm in Qatar linked to two human cases of the infection in October, 2013. METHODS We took nose swabs, rectal swabs, and blood...
As of June 19, 2015, the World Health Organization had received 1,338 notifications of laboratory-confirmed infection with Middle East respiratory syndrome coronavirus (MERS-CoV). Little is known about the course of or treatment for MERS-CoV in pregnant women. We report a fatal case of MERS-CoV in a pregnant woman administered combination ribavirin-peginterferon-α therapy.
On 26 May 2015, an imported Middle East respiratory syndrome coronavirus (MERS-CoV) was identified in Guangdong Province, China, and found to be closely related to the MERS-CoV strain prevalent in South Korea. The full genome of the ChinaGD01 strain was sequenced and analyzed to investigate the epidemiology and evolution of MERS-CoV circulating in South Korea and China.
هدف از این رساله مطالعه ی خواص اپتیکی چاه های کوانتومی مربعی جفت شده متقارن و نامتقارن می باشد. در این رساله ما با استفاده از روش ماتریس انتقال معادله ی شرودینگر را به طور تحلیلی حل کرده ایم و ویژه مقادیر انرژی و توابع موج را بدست آورده ایم. سپس با استفاده از رهیافت ماتریس چگالی خواص اپتیکی خطی و غیر خطی از قبیل ضرایب جذب اپتیکی، تغییرات ضرایب شکست و ضریب یکسوسازی نوری بدست آمده اند. در ادامه ت...
reaction (RT-PCR) assay was developed to rapidly detect the severe acute respiratory syndrome–associated coronavirus (SARS-CoV). The assay, based on multiple primer and probe sets located in different regions of the SARSCoV genome, could discriminate SARS-CoV from other human and animal coronaviruses with a potential detection limit of <10 genomic copies per reaction. The real-time RTPCR assay ...
Pharmacophore-based virtual screening is an effective, inexpensive and fast approach to discovering useful starting points for drug discovery. In this study, we developed a pharmacophore model for the main proteinase of severe acute respiratory syndrome coronavirus (SARS-CoV). Then we used this pharmacophore model to search NCI 3D database including 250, 251 compounds and identified 30 existing...
زمینه و هدف: در حال حاضر شواهد فزاینده‌ای وجود دارد که نشان می‌دهد مسیرهای پیش‌التهابی توسط سلول‌های T (که IL-17 IL-22 را ترشح می‌کنند)، تعدیل می‌شوند، نقش مهمی کنترل سوخت‌وسازی دارند. هدف از پژوهش بررسی اثر تمرین هوازی همراه با مصرف عصارة آبی سیر بر بیان IL-17، مقاومت به انسولین موش‌های صحرایی دیابتی استرپتوزوتوسین است.مواد روش‌ها: این تحقیق تجربی،40 سر موش نر (سن 5 هفته وزن 24/15 ± 12/162 گ...
ABSTRACT Complete Middle East respiratory syndrome coronavirus (MERS-CoV) genome sequences were obtained from nasal swabs of dromedary camels sampled in the Kingdom of Saudi Arabia through direct analysis of nucleic acid extracts or following virus isolation in cell culture. Consensus dromedary MERS-CoV genome sequences were the same with either template source and identical to published human ...
The main protease (M(pro)) of severe acute respiratory syndrome coronavirus (SARS-CoV) plays an essential role in the extensive proteolytic processing of the viral polyproteins (pp1a and pp1ab), and it is an important target for anti-SARS drug development. It was found that SARS-CoV M(pro) exists in solution as an equilibrium of both monomeric and dimeric forms, and the dimeric form is the enzy...
