با گذراندن سوزن باریکی در غده لنفاوی قلب سگ که روش آن تحت عنوان clnc ذکرشده است (cannulation of cardiac lymph node) لنف بدست آمده با آنچه از راه رگ لنفاوی قلب بدست میاید و با عنوان clve نشان داده شده است (cardiac lymph vessel cannulation) از نظر مقدار پروتئین و جریان لنف مقایسه و مشاهده گردید که روش clnc ساده تر و بیشتر مقرون بموفقیت بوده و مقدار لنفاوی و پروتئین آن نیز با آنچه که توسط clvc بدس...
To improve the specificity of biochemical markers of myocardial infarction (MI) a method to measure cardiac troponin-I (CTn-I) was developed. CTn-I is a protein unique to cardiac muscle and is released after MI. Consecutive 150 patients admitted to the coronary care unit was studied. Value of CTn-I was determined in all samples. CTn-I concentration in the MI patients group was increased com...
Muscle tissue, skeletal muscle as well as cardiac muscle, is commonly affected in mitochondrial disorders. One explanation for this observation is that muscle tissue has a high-energy demand and therefore is more sensitive to a deficiency of mitochondrial energy production than some other tissues. In mitochondrial disorders, skeletal muscle tissue may be affected primarily by defective respi...
Background & Aims: Recently, results of studies show that serum levels of vitamin D considered as a risk factor for cardiovascular system as well as important markers of skeletal muscle and body mass index (BMI). Therefore, the purpose of this study was to investigate the relationship between echocardiography indices, muscular strength, and BMI with vitamin D in sedentary postmenopausal women. ...
Background: Oxidative stress plays a key role in the onset and development of diabetes Complications, Including diabetic cardiomyopathy. The purpose of this study was to investigate the role of dichloroacetate (DCA) on SOD and GPX expression following six weeks’ endurance training in cardiac muscle of diabetic male rats. Methods: In this experimental study, 64 male Wistar rats were selected an...
Background & Aims: Regarding the effect of diabetes on vascularization processes and since the beneficial effects of aerobic exercise on the cardiovascular system have been proven, therefore, the aim of this study was to determine the effect of aerobic exercise on muscle angiogenesis and downstream factors of the PI3KR2 pathway in cardiac tissue of diabetic rats. Materials & Methods: Twenty di...
The biochemical mechanisms by which octopamine, catecholamines and the peptide proctolin exert their actions on Limulus cardiac muscle were investigated. Amines produced long-lasting increases in the amplitude of contractions evoked by electrical stimulation. At 10(-5) mol l-1, the apparent order of potency for amine-induced increases in evoked contraction amplitude was dopamine approximately e...
