Abstract Polyethylene terephthalate (PET) is a material developed by industrial manufacturers, but which also abundantly found as recovery in many daily activities. Since it largely used the textile industry, objective of this work to improve flow polyethylene spinning an application using certain polymers produce quality fabrics. The methodology adopted here interpose layers balls form porous ...

BACKGROUND Blood hyperviscosity has been acknowledged to be a complicating factor in polycythaemia and hyperproteinaemia. Hyperleucocytosis has also been implicated in hyperviscosity and may be a basis for therapeutic leukapheresis. AIMS This issue in the series seeks to determine the association and correlation between whole blood viscosity and white blood cell count (WBCC), with a view to a...

BACKGROUND Increased blood and plasma viscosity, hematocrit, fibrinogen, and activation of coagulation and leukocytes have been reported in patients with claudication; however, their associations with symptomatic and asymptomatic peripheral arterial disease have not been reported in an epidemiological study. METHODS AND RESULTS Blood and plasma viscosity, hematocrit, fibrinogen, urinary fibri...

benign prostatic hyperplasia (bph) is the most common condition in aging men, associated with lower urinary tract symptoms. it is caused due to the augmented levels of the androgen dihydrotestosterone. dutasteride, a 5α-reductase inhibitor has been recommended for the treatment of bph upon oral administration. however, long term oral administration of dutasteride may cause sexual problem in man...

Solutions of modified cell-free hemoglobin, prepared from outdated red blood cells, have been developed during the past decade to circumvent the increasing need for allogeneic blood. Despite improvements in the safety and efficacy of these solutions, undesirable effects such as an increase in vascular tone leading to hypertension have not been fully resolved, which might hinder their clinical u...

BACKGROUND AND PURPOSE Aortic stenosis, causing flow abnormalities, disturbs the normal hemodynamics in the common carotid arteries. The aim of the present study was to investigate the remodeling process of the common carotid arteries after surgical correction of aortic stenosis. METHODS Eleven subjects with aortic stenosis were studied before and 1 and 6 months after aortic valve replacement...

The mixing dynamics of granular materials immersed in a liquid was experimentally studied in a quasi-2D rotating drum. A DV (SONY DCR-TRV900 NTSC) motion corder analyzer was used to record the motions of granular materials. The effects of interstitial fluid viscosity and filling degree on the mixing index, mixing rate constant, and dynamic repose angle in the rotating drum were investigated and...

AIM This study investigates the changes in hemorheologic parameters resulting from exercise followed by a standard meal. METHODS In twelve moderately active men a period of exercise on a bicycle ergometer for 30 min at 60% VO2max was followed by a test meal or by 30 min rest. Venous blood was sampled for further analysis at baseline, after exercise, and after the meal/rest period. RESULTS T...
