The purpose of this study is to develop a mathematical model for studying the magnetic field effect on blood flow through an axially non-symmetric but radially symmetric atherosclerotic artery. Herschel-Bulkley equation has been taken to represent the non-Newtonian character of blood. The response of magnetic field, stenosis height, shape parameter on velocity, volumetric flow rate in stenotic ...

The mechanisms underlying cerebral vasodilatation during hypercapnia are not fully understood. To examine the role of nerves and prostaglandins in the regulation of basal blood flow and in hypercapnia-induced vasodilatation in the cerebral blood vessels of rabbit.Cerebral blood flow was measured by laser Doppler flow-meter in 18 NZW rabbits anesthetized with sodium pentobarbital.  Tetrodetoxin ...

in this research, we investigated the effects of medicinal plants, prebiotic and probiotic as alternatives to antibiotics on the growth performance, immune response and blood cholesterol in broilers. a total of 288 one- day-old broiler chicks (cobb 500) were randomly assigned to 6 treatments and replicated 4 times with 12 chicks per pen in a completely randomize design experiment in 6 wk. diet ...

beta-2 adrenoceptors in blood vessels are one of the active factors that play a role in regulation of tissue blood flow. in diabetic angiopathy, responsiveness of these receptors is decreased, while that is increased in inflammation. according to these opposite effects, the aim of this study was to investigate the vasodilatory response of knee joint blood vessels to salbutamol (beta-2 adrenocep...

the angiotensin 1-7 (ang 1-7), is abundantly produced in kidneys and antagonizes the function of angiotensin ii through mas receptor (masr) or other unknown mechanisms. in the current study, the role of masr and steroid hormone estrogen on renal blood flow response to ang 1-7 administration was investigated in ovariectomized (ov) female rats. ov female wistar-rats received estradiol (500 µg/kg/...
