AIM The goal of this study was to evaluate selected parameters of the Doppler curve of the pericallosal artery at children with hydrocephalus. METHODS 12 patients with hydrocephalus were divided into two groups. Group 1 comprised children needing cerebrospinal fluid drainage, and group 2 comprised children without any indication for drainage or with an already inserted well-functioning draina...

Background and Objective: Cerebral Arteriovenous Malformation (CAVM) hemodynamic is disease condition, results changes in the flow and pressure level in cerebral blood vessels. Measuring flow and pressure without catheter intervention along the vessel is big challenge due to vessel bifurcations/complex bifurcations in Arteriovenous Malformation patients. The vessel geometry in CAVM patients are...

The advantages and inadequacies of the currently available techniques to measure regional blood flow in the lower limbs are being reviewed. Thermodilution technique and local 133xenon washout technique have the advantage of allowing determination of blood flow during exercise, while venous occlusion plethysmography and pulsed-Doppler duplex ultrasonography only allow determination of blood flow...

In this study, we characterized cerebral blood flow changes by assessment of blood flow parameters in neck arteries using carotid duplex ultrasonography and predictive factors for these hemodynamic changes. Hemodynamic variables were measured before and during hemodialysis in 81 patients with an arteriovenous access in their arm. Hemodialysis produced significant lowering in peak systolic veloc...

objective(s): nucleus raphe magnus (nrm) that is involved in the regulation of body temperature contains nitric oxide (no) synthase. considering the effect of no on skin blood flow control, in this study, we assessed its thermoregulatory role within the raphe magnus. materials and methods: to this end, tail blood flow of male wistar rats was measured by laser doppler following the induction of ...

Background Endometrial receptivity is one of parameters which determine the reproductive outcome in in vitro fertilization programs. A good blood supply towards the endometrium is usually considered to be an essential requirement for implantation. Blood vessels of the endometrium can be detected by transvaginal color and pulse Doppler sonography. Color Doppler assessment permits better visualiz...

A study of the steady flow of blood through a horizontally symmetric artery with mild stenosis is presented by considering blood as a micropolar fluid. The viscosity of blood is considered as radial coordinate dependent. The non-linear pressure equations governing the flow are solved numerically using finite difference technique. The effects of micropolar fluid parameters and hematocrit on axia...

this study investigated the effects of coenzyme q10 (coq10) supplementation on hematological, enzymes activities and biochemical parameters in broilers with pulmonary hypertension syndrome (phs).two hundred and forty 1-d-old ross 308 male broiler chicks were randomly allocated into 3 groups with 4 replicates. from d 14, the diets were supplemented with coq10 at levels of 0, 20 and 40 mg/kg, res...

this study was conducted to assay the use of saturejahortensis l. (savory) essential oil in the drinking water on broiler production and blood glucose, uric acid, creatinin and cholesterol. four hundred and twenty day old broiler chickens (ross 308) was used in a completely randomized design with 6 treatments and 5 replicate. experimental treatments included: 1) control, 2) tween (a solvent for...
