The effects of endothelin-1 (ET-1) infusion on blood flow (Q˙G) and O2 uptake (V˙o 2G) were examined in the small intestine of anesthetized dogs ( n = 10). Arterial and venous flows of a gut segment were isolated, and the segment was perfused at constant pressure. Arterial and gut venous blood samples were taken, gut perfusion pressure andQ˙G were measured, and O2 extraction ratio (OERG) andV˙o...
بررسی تنوع بیماریزایی در جمعیت قارچ rhizoctonia solani ، عامل بیماری سوختگی غلاف برنج در استان گیلان
قارچrhizoctonia solani ag-1 ia (تلئومورف thanatephorus cucumeris) عامل سوختگی غلاف، یکی از بیمارگرهای مهم برنج می باشد. با توجه به اهمیت بیماری و عدم وجود اطلاعات کافی از تنوع بیماریزایی جمعیت های این قارچ در ایران، 83 جدایه از مناطق مختلف برنجکاری استان گیلان جمع آوری و برای این منظور مورد مطالعه قرار گرفت. برای تعیین گروه آناستوموزی، همه جدایه های به دست آمده به همراه جدایه های استاندارد ag-1...
In vitro sensitivity to porphyrin-mediated photodynamic therapy (PDT) has been examined in cell lines resistant to hyperthermia. Parental (1IA-1) and heat-resistant (3012) Chinese hamster fibroblasts as well as parental (RIF-1) and temperature-resistant (TR-4, TR-5, and TR-10) mouse radiation-induced fibrosarcoma cells were evaluated for thermal and PDT sensitivity. Quantitative survival curves...
patients with schizophrenia experience a vast range of cognitive disorders. among these deficits, deficit in attention processes realm can be named. the goal of the current study is the comparison of maintenance of attention in patients with schizophre!1ia, major depression and normal individuals. to do so, 32 schizophrenic patients (!5 acute patients and 17 chronic patients), 32 patients with ...
An electron microscopic study on the fine structural differences of motor endplates among the red, white and intermediate muscle fibers of the rat intercostal muscles was made and the following results were obtained. 1. In the motor endplate of the red fiber, the junctional folds were poorly developed and their number was small. 2. In the motor endplate of the white fiber, the junctional folds ...
Accurate assessment of atherosclerotic plaque characteristics and the subsequent tailoring of optimal therapy holds great promise for preventing acute coronary syndromes (ACS) and life-threatening sequelae (1). Combined use of optical coherence tomography (OCT) and intravascular ultrasound (IVUS) was proposed as a potential method for accurate assessment of plaque characteristics and vulnerabil...
