The purpose of this investigation was to assess the effect of captopril on both systemic (P.a) and pulmonary arterial pressures (PPA) in patients with high-altitude pulmonary hypertension (HAPH). Seventeen patients (mean age 44±6.8 years) with HAPH and mild to moderate systemic arterial hypertension were included in the study. All patients underwent right heart catheterization with measurem...
This paper presents a new circuit to configure power amplifier (PA) for return-to-zero on-off-keying (RZ-OOK) transmitters. The proposed PA works as a multimode structure with configurable data rate and output power. The programmable data rate function is achieved by duty cycle adjustment of input data and producing input RZ-data by a simple circuit, which leads to a linear scale of data rate w...
Introduction: The role of serotonergic fibers in avoidance learning is controversial. Involvement of the dorsal raphe nucleus (DRN), the main source of hippocampal projecting serotonergic fibers in acquisition, consolidation and retrieval of passive avoidance (PA) learning, was investigated by functional suppression of this area. Materials and Methods: DRN functional inactivation was done by li...
background: pectin is composed of complex polysaccharides that can inhibit cancer metastasis and proliferation with no evidence of toxicity. in the present study, the apoptotic and necrotic effects of pectic acid (pa) on the rat pituitary gh3/b6 tumor cells has been investigated. methods: gh3/b6 cells were cultured in the ham’s f12 medium enriched with 15% horse serum and 2.5% fetal bovine seru...
We describe MUSST, a multilingual syntactic simplification tool. The tool supports sentence simplifications for English, Italian and Spanish, and can be easily extended to other languages. Our implementation includes a set of general-purpose simplification rules, as well as a sentence selection module (to select sentences to be simplified) and a confidence model (to select only promising simpli...
در این مطالعه یک روش استخراج جذبی میله چرخان (sbse) به همراه مشتق سازی توسط معرف (-)-منتیل کلروفرمات (mcf) و در نهایت آنالیز با استفاده از سیستم hplc-uv با ستون فاز معکوس c18 برای تعیین مقدار انانتیومرهای کارودیلول در داروهای خوراکی بررسی شد. روش استخراج جذبی sbse، روشی عاری از حلال، ارزان، ساده و موثر است و تنها نقطه ضعف آن، محدودیت آن برای استخراج ترکیبات غیرقطبی یا نیمه قطبی است. بنابراین، ب...
background physical activity (pa) patterns during pregnancy have not been explored in depth and most previous studies lack assessment of variables such as type, frequency, duration and intensity of activity. objectives this study had two goals: 1) to analyze pa patterns during pregnancy according to weekly time spent on different types of activity; and 2) to determine women’s perception about h...
Foreign language learners tend to avoid phonological difficulties and simply transfer sounds whether from their L1 or any pre-existing L2. Phonological awareness (PA) gives students an active role in understanding their own potential in improving pronunciation through several methods. However, such methods are likely to be restricted to only passive learning methods, such as repetition, reading...
Introduction: Diagnostic reference level (DRL) is a useful tool for the promotion of optimization. The national DRLs (NDRLs) are useful, brief, and robust guidelines for optimizing radiation protection in a country. The aim of this study was to extract the local DRLs (LDRLs) for some common radiologic examination in Sabzevar county. Materials and Methods: There are eight radiology departments ...
ABSTRACT The purpose of this study was to compare the resistance of propiobacteriom acne (PA) and staphylococcus epidermis(SE) to antibiotics in patients that have been treated with antibiotics, With those cases without previous history of therapy as the control group. 60 patients were included in this study. At the time of sampling, all 30 cases of study group had been on therapy for ...
