BACKGROUND Combination therapy has been proposed in treatment algorithms for idiopathic pulmonary arterial hypertension (IPAH), so the additional effects of bosentan in IPAH patients already treated with high-dose epoprostenol (EPO) was evaluated in the present study. METHODS AND RESULTS Bosentan (62.5 mg twice daily) was administered to 8 IPAH patients already being treated with high-dose EP...
Patients with pulmonary arterial hypertension (PAH) exhibit a limited increase in stroke volume on exercise, and the heart rate (HR) increases may reflect the main mechanism that allows cardiac output to increase. The current prospective study documented the contribution of HR to the 6-min walking distance (6MWD) in idiopathic (IPAH) and nonidiopathic PAH. Eighty-three patients (46 IPAH and 37 ...
Endothelin receptor antagonists are used to treat idiopathic pulmonary arterial hypertension (IPAH), but human pulmonary arterial endothelin receptor expression is not well defined. We hypothesised that disease and treatment would modify normal receptor distribution in pulmonary resistance arteries of children. Using immunohistochemistry and semiquantitative analysis, we investigated endothelin...
Idiopathic pulmonary arterial hypertension (IPAH) is a pulmonary vasculopathy of unknown aetiology. Dyspnoea, peripheral airway obstruction and inefficient ventilation are common in IPAH. Data on respiratory muscle function are lacking. This prospective single-centre study included 26 female and 11 male patients with IPAH in World Health Organization functional classes II-IV. Mean+/-SD pulmonar...
We previously reported that osteoprotegerin (OPG) is regulated by pathways associated with pulmonary arterial hypertension (PAH), and is present at elevated levels within pulmonary vascular lesions and sera from patients with idiopathic PAH (IPAH). Since OPG is a naturally secreted protein, we investigated the relationship between serum OPG and disease severity and outcome in patients with IPAH...
Pulmonary hypertension (PHT) is associated with increased vascular resistance due to sustained contraction and enhanced proliferation of pulmonary arterial smooth muscle cells (PASMC); the abnormal tone and remodeling in the pulmonary vasculature may relate, at least in part, to decreased cyclic nucleotide levels. Cyclic nucleotide phosphodiesterases (PDEs), of which 11 families have been ident...
Rationale Although pulmonary endarterectomy (PEA) is potentially curative in Chronic Thromboembolic Pulmonary Hypertension (CTEPH), some patients have distally distributed disease that is not amenable to surgery. The aetiology and characteristics of this patient group are currently not well understood. Objectives This study compares the baseline demographics and outcomes of subjects with distal...
Pulmonary hypertension syndrome (PHS; ascites) in fast growing meat-type chickens (broilers) is characterized by the onset of idiopathic pulmonary arterial hypertension (IPAH) leading to right-sided congestive heart failure and terminal ascites. Intravenous microparticle (MP) injection is a tool used by poultry geneticists to screen for the broilers that are resistant (RES) or susceptible (SUS)...
مقدمه: شیگلا باسیل گرم منفی روده ای است که عفونت های ناشی از آن مشکلات جدی را در کشورهای پیشرفته و در حال توسعه ایجاد کرده است. هدف از این مطالعه، به کارگیری روش رنگ سنجی بر پایۀ نانوذرات طلا جهت تشخیص سریع شیگلا فلکسنری با استفاده از محصول تکثیریافتۀ ژن ipah است. مواد و روش ها: در این مطالعه برای شناسایی جنس شیگلا از یک جفت آغازگر اختصاصی برای تکثیر ژن ipah به روش واکنش زنجیره ای پلیمراز است...
زمینه و اهداف: شیگلا از عوامل شایع اسهال و مرگ و میر در کودکان زیر 10 سال در کشورهای در حال توسعه شناخته شده است. روش های روتین ازمایشگاهی برای جداسازی انواع شیگلا وقت گیر و هزینه بر می باشد, در این مطالعه به جداسازی زیر گونه های شیگلا سونئی از نمونه بیماران مبتلا به دیسانتری بر اساس اهمیت تشخیص ژن تهاجمی و اختصاصی ipah)) با pcr در مقایسه با روشهای روتین بیوشیمیایی و سرولوژیک پرداخته شده است....
