Non-alcoholic fatty liver disease (NAFLD) is a widespread closely associated with obesity and metabolic disorders. Noninvasive instrumental markers are of great importance in the diagnosis NAFLD. The aim present investigation was to study correlation Hamaguchi score prevalence peripheral arterial atherosclerosis evaluate diagnostic value relation presence carotid lower limb stenoses.

Abstract. Sudden cardiac death in athletes is often related to anomalies coronary origin, which may affect how arteries supply blood the heart; this highlights importance of understanding perfusion. Studies for simulation and predictions flow under normal or disease conditions are many. Numerical simulations can provide rich information about with reduced costs relation physical models. Correct...

Latar Belakang: Rumah sakit memiliki standariasi pemilihan sekuens yang digunakan untuk pemeriksaan MRA. Di Instalasi Radiologi RSUD Arifin Achmad Provinsi Riau hanya menggunakan satu TOF dari dua sekuen tindakan MRA non kontras yaitu dan PC. Sehubungan dengan hal tersebut, terdapat perlu tujuan mengetahui menghasilkan citra pembuluh darah renal baik.
 Metode: Penelitian ini merupakan pene...

The coronary vasculature located distal to a chronic occlusion (collateral-dependent) has been shown to exhibit altered reactivity to vasoactive agonists. Thus we evaluated effects of chronic coronary artery occlusion on vasomotor responsiveness of collateral-dependent arteries isolated from a canine model of Ameroid occlusion of the left circumflex (LCX) coronary artery. We compared in vitro r...

Dystrophin has a key role in striated muscle mechanotransduction. In mice lacking the gene encoding for dystrophin (mdx mice), the absence of dystrophin and several other proteins of the dystrophin-glycoprotein complex induces a defect in flow (shear stress)-mediated NO-dependent dilation (FMD). Because the endothelium is essential for the adaptation of arteries to chronic changes in blood flow...

BACKGROUND Hypercholesterolemia is one of the major modifiable risk factors for atherosclerosis of the coronary and carotid arteries. Although transcranial Doppler (TCD) studies of the cerebral arteries are indicative of decreased cerebral blood flow velocities in patients with hypercholesterolemia, the number of these studies has been limited. The aim of this study was to assess the hemodynami...

Carotid and tail arteries from 20-week-old spontaneously hypertensive rats (SHR) and Wistar-Kyoto rats (WKY) were used to compare mechanics and biochemical properties. Measurements of pressure-diameter relations were made on isolated segments under conditions of active (145 mM K+) and passive (O mM Ca+2 and 2 mM EGTA) smooth muscle. Connective tissue, water and electrolyte contents, and extrace...

Relaxant responses to vasodilators, including nitroglycerin, sodium nitroprusside, prostaglandin I2 sodium salt (PGI2), prostaglandin E1 (PGE1), diltiazem hydrochloride and adenosine, were compared in helical strips of dog coronary arteries of different sizes and in coronary and mesenteric arterial strips. The relaxant responses to nitroglycerin, sodium nitroprusside, diltiazem and adenosine we...

The aim of this study was to examine the morphological and functional changes in rabbit mesenteric arterial tissue cultured with fetal bovine serum. In the endothelium-denuded arteries cultured under a serum-free condition for one week (serum-free arteries), morphology of the smooth muscle layer was intact. In the serum-free arteries, high K+ -induced contraction did not change but norepinephri...

The role of calcium (Ca(2+)) released from intracellular stores and the entry of extracellular Ca(2+) for vasopressin (AVP)-induced responses in large and small, human, intramyometrial arteries was investigated. There was no statistical difference as revealed by pD(2) values (-log EC(50)), in the sensitivity of large and small vessels to AVP. Nimodipine caused an inhibition of contractions indu...
