The effect of endogenous serotonin on long-term potentiation (LTP) in region CAI was studied by blocking 5-HT2 receptors with ketanserin in rat hippocampal slices. Such a block significantly en-hanced long-term potentiation of the CAI population spike induced by high frequency stimulation of the schaffer collateral/ commissural pathway. This implies that serotonin acts on 5-HT2 receptors in CAI...
PURPOSE Preclinical and clinical investigation of the combination of the antiangiogenesis/anti-invasion agent carboxyamido-triazole (CAI) administered with the cytotoxic agent paclitaxel (PAX). EXPERIMENTAL DESIGN Colony-forming assays were used to test the activity of CAI plus PAX on A2780 human ovarian cancer. The sequence of CAI followed by PAX (CAI>Pax) was modeled in nude mice to test fo...
Many studies have indicated that nuclear DNA content evaluation can be used to predict biological behavior of transitional cell carcinoma (TCC) of the bladder. Some authors also indicated that static cytometry is more useful in DNA content analysis than flow cytometry. The aim of the present study was to evaluate the prognostic significance of DNA ploidy in TCC of the bladder, performed by usin...
Central adrenal insufficiency (CAI) in acromegaly may be related to pituitary adenoma or induced by various medical treatments, transsphenoidal neurosurgery (TNS) or radiotherapy (RT), alone or combined. We assessed the role of all available treatments for acromegaly in inducing CAI. We retrospectively studied 97 patients. CAI was diagnosed if morning serum cortisol was <138 nmol/l, or if its r...
In the heart, membrane voltage (Vm) and intracellular Ca (Cai) are bidirectionally coupled, so that ionic membrane currents regulate Cai cycling and Cai affects ionic currents regulating action potential duration (APD). Although Cai reliably and consistently tracks Vm at normal heart rates, it is possible that at very rapid rates, sarcoplasmic reticulum Cai cycling may exhibit intrinsic dynamic...
در این شبیه سازی، محیط گازی را محیطی پیوسته و جریان گاز را جریانی آرام فرض کرده ایم. همچنین از اثرات تابش صرف نظر نموده و گازها را در محیط پلاسما ایده آل در نظر می گیریم. در نتیجه این شبیه سازی که با استفاده از نرم افزارفلوئنت انجام شده است، نرخ لایه نشانی کربید سیلیسیوم و همچنین پروفیل لایه نشانی محاسبه شده آن و نیز اثر پارامتر های مختلف موثر بر لایه نشانی شامل: نرخ ورودی گاز، دمای سطح زیر لای...

تحقیق حاضر با هدف " بررسی تأثیر اینترنت در دسترسی به اطلاعات مرتبط با سلامت از دیدگاه بیماران و کارشناسان درمان " انجام گرفته است .روش این تحقیق پیمایشی و از ابزار پرسشنامه جهت اندازه گیری استفاده شده است.. جهت سنجش دیدگاه دو گروه نسبت به تدوین دو پرسشنامه اقدام شد و پس از پر شدن پرسشنامه ها ، جداول توصیفی و استنباطی به دست آمده از طریق نرم افزار spss مورد تحلیل و بررسی قرار گرفت. برای انتخاب ج...
We investigated the contribution of the intracellular calcium (Cai ) transient to acetylcholine (ACh)mediated reduction of pacemaker frequency and cAMP content in rabbit sinoatrial nodal (SAN) cells. Action potentials (whole cell perforated patch clamp) and Cai 2? transients (Indo-1 fluorescence) were recorded from single isolated rabbit SAN cells, whereas intracellular cAMP content was measure...
