new study identifies a possible new function for endostatin, the potential cancer-killer that checks blood vessel growth. Within the developing kidney, endostatin may help regulate the branching that establishes the network of urine-collecting tubules. Cells in the ureteric bud divide and change shape to form the plumbing system of the kidney. Because endostatin inhibits blood vessel formation,...
Introduction: Providing an effective education by healthcare workers is very important in improving the quality of health services and patients' lives. Effective education faces a variety of challenges, which results in the low productivity of experienced health care providers. The aim of this study was to explain the experiences of health care providers about barriers of client education in Gh...
background: several echocardiographic markers have been introduced to assess the left ventricular (lv) mechanical dyssynchrony. we studied dyssynchrony markers and the latest lv activation site in heart failure patients with and without left bundle branch block (lbbb). methods: conventional echocardiography and tissue velocity imaging were performed for 78 patients (lv ejection fraction ≤ 35%),...
Background: Every year 1.2 millions of people are killed in road accident, and speeding is a major contributor road crashes among young driver. Accounting 40% of fatal crashes involved speeding. The purpose of this study was determining predictor of speeding intention among young driver 19-25 years old young driver in ghaemshahr based on Prototype Willingness Model. Materials and methods: I...
چکیده : در این پایان نامه طراحی و ساخت کوپلر branch-line سه بانده با استفاده از ساختاری که در سه فرکانس جداگانه می تواند جانشین خط انتقال ?/4 با امپدانس مشخصه z_c در یک کوپلر branch-line معمولی شود انجام می شود. این ساختار به گونه ای طراحی می شود که بتواند در فرکانس طراحی f_0 فاز 3?/2 ، در فرکانس تشدید f_1 باند پایین فاز ?/2، در فرکانس تشدید f_2 باند بالا فاز 5?/2 و امپدانس مشخصه z_c مطلوب را د...
background: isolated right bundle branch block (rbbb) is a common finding in the general population. the atrioventricular node (avn) artery contributes to the blood supply of the right bundle branch. our hypothesis was that the anatomy of the avn artery and the pattern of dominancy differ between subjects with and without rbbb. methods: w e retrospectively studied the coronary angiography of 92...
