بهینه‌سازی شرایط PCR برای دو ژن CHD-W و CHD-Z جهت تفکیک جنسیت در قناری

تعیین جنسیت قناری بر پایۀ ژن CHD مربوط به کروموزوم‌های جنسی با استفاده از پر

 هدف از این تحقیق استفاده از پر به­عنوان روشی ساده، سریع، کم­هزینه، بدون خطر و ایمن و مطمئن برای تعیین جنسیت قناری در اوایل تولد، برای کمک به برنامه‌های اصلاح نژادی و پرورش این پرنده است. شکل ظاهری جنس نر و مادۀ بسیاری از پرندگان از جمله قناری تا حدودی همانند هم بوده و تشخیص جنسیت آن‌ها بسیار دشوار است. با استفاده از این روش مولکولی بر پایۀ اختلاف طول ژن Chromo-helicase-DNA(CHD) در کروموزوم­های...

Risk Factors For CHD

Coronary heart disease (CHD) is the leading cause of death and a significant cause of morbidity among North American women.1 Because CHD typically develops one to two decades later in females than in males, the importance of cardiovascular disease in this group has been overlooked. Studies of CHD treatment have shown a bias against the treatment of women with CHD. A recent survey by the Centers...

Fatty acids and CHD.

During the last century much evidence has accumulated to suggest that from a public health perspective the type of fat is more important than the amount of fat. Saturated and trans-fatty acids increase and both n-6 and n-3 PUFA decrease the risk of CHD. Most of the knowledge about the effects of dietary fatty acids on CHD risk is based on observational studies and controlled dietary experiments...

SnapShot: Chromatin Remodeling: CHD

Mediterranean diet in secondary prevention of CHD.

OBJECTIVE To summarise our present knowledge on the Mediterranean diet in secondary prevention of CHD. DESIGN Review of literature. SETTING Adult coronary patients. SUBJECTS CHD patients at high risk of cardiac death. RESULTS The two main causes of death in these patients are sudden cardiac death (SCD) and chronic heart failure (CHF). The main mechanism underlying recurrent cardiac even...

False positives on diagnostic tests for CHD.

acceleration occurs at the time of valve closure, apparently as a result of the narrowing of the orifice in the face of this forward flow. In contrast, aortic valve closure occurs after cessation of forward flow in aortic stenosis,8 and hence no acceleration and no resulting augmentation of the murmur would be expected. Although the editorial raised a number of other points, with which we disag...
