background: in the current iranian poultry industry, antibiotics are the most frequently used additive in poultry feeds to increase productivity. the negative effects on human health, resulting from the consumption of chicken whose feeds contain antibiotics, makes finding an appropriate alternative of great importance. as a result of their nature, herbal extracts could be specifically considere...

This study shows how sensitivity analysis and subset selection can be employed in a cardiovascular model to estimate total systemic resistance, cerebrovascular resistance, arterial compliance, and time for peak systolic ventricular pressure for healthy young and elderly subjects. These quantities are parameters in a simple lumped parameter model that predicts pressure and flow in the systemic c...

An attempt has been made to investigate the wall shear stress, resistance parameter and flow rate across mild stenosis situated symmetrically on steady blood flow through blood vessels with uniform or non-uniform cross-section by assuming the blood to be Non-Newtonian, incompressible and homogeneous fluid. An analytic solution for Power law Fluid, Bingham Plastic fluid, Casson Fluid has been ob...

Background and Aim: Inactivity increases the risk of chronic diseases. The aim of the present study was to investigate the acute changes in Normetanephrine and glucose in boxing with Kinect Xbox with and without blood flow restriction as an alternative to aerobic exercise during quarantine in young non-athletes. Material and Methods: Fourteen healthy non-athlete individuals with a range of 20 ...

Changes in intraovarian arterial blood flow were monitored by means of colour-coded and pulsed Doppler ultrasonography in Beagle bitches during the normal oestrous cycle (n = 11) and pregnancy (n = 3), and at PGF(2alpha)-induced luteolysis (n = 4). The ultrasonographic findings were related to the reproductive stage of the bitch, as determined by vaginoscopical and cytological criteria, and by ...

AIM To investigate the changes of hemodynamic and laboratory parameters during the course of acute liver failure following acetaminophen overdose. METHODS Eight pigs underwent a midline laparotomy following jejunal catheter placement for further acetaminophen intoxication and positioning of a portal vein Doppler flow-probe. Acute liver failure was realized by intrajejunal acetaminophen admini...

PURPOSE To investigate the feasibility of quantitative parameter extraction from a mathematical model fitted to renal artery magnetic resonance flow data. MATERIAL AND METHODS A total of 16 subjects, eight patients, and eight normal controls, were examined with cine phase-contrast velocity measurements, and blood flow data from the aorta and both renal arteries were extracted by means of cont...
