Background: The ineffectiveness of hemodialysis fistulas causes high costs and increases mortality and morbidity rates. The efficacy of drug-coated balloon and nondrug-coated balloon in dysfunctional arteriovenous Fistula was evaluated over six month period. Methods: In this randomized clinical trial, a total of a total of 50 hemodialysis patients who referred to Imam Reza Hospital in Kermansh...

We are developing an intravenous respiratory assist catheter, which uses hollow-fiber membranes wrapped around a pulsating balloon that increases oxygenation and CO2 removal with increased balloon pulsation. Our current pulsation system operates with a constant rate of pulsation and delivered balloon volume. This study examined the hypothesis that random balloon pulsation would disrupt fluid en...

the present paper deals with the prediction of three-dimensional fluid flow and heat transfer in rib-roughened ducts of square cross-section. such flows are of direct relevance to the internal cooling system of modern gas turbine blades. the main objective is to assess how a recently developed variant of a cubic non-linear model (proposed by craft et al. (1999)), that has been shown to produce ...

Placement of an intragastric balloon is a nonsurgical treatment for weight loss [1, 2]. Balloon retrieval can be difficult, however: forcing or persisting can cause perforation or esophageal laceration, as well as extending the anesthesia time [3–5]. The patient should be on a liquid diet for 2 days, drinking diet coke, which cleans away any residual food around the balloon, and then only water...

Abstract To explore the optimization seismic design of frame-multi-ribbed composite wall structure, firstly finite element model a six story structure is established based on software SAP2000. Secondly critical parameters multi under action are analysised using analysis software. Finally response different rib combinations and optimal arrangement rule studied. The results reveals that lateral s...

talented individuals, who are bleeding from the nose, usually do not go to the doctor, except in case of sever and unusual bleeding. because traditional method of treatment is not effective in nasopharanx bleeding, so malcolm harvey explain brighton epistaxis balloon as a new method  for controlling nasopharanx bleeding through the paper. epistaxia usually happen in the anterior part of the nas...

ZUCKER, IRVING H., LEONARD SHARE,AND JOSEPH P. GILMORE. Renal effects of left atrial distension in dogs with chronic congestive heart failure. Am. J. Physiol. 236(4): H554H560, 1979 or Am. J. Physiol.: Heart Circ. Physiol. 5(4): H554H560, 1979.-The renal response to left atrial balloon inflation in normal dogs was compared with that in dogs with chronic congestive heart failure (CHF). CHF was i...

This study describes the retrieval of water vapor vertical distributions in the upper troposphere and lower stratosphere (UTLS) altitude range from space-borne observations of the scattered solar light made in limb viewing geometry. First results using measurements from SCIAMACHY (Scanning Imaging Absorption spectroMeter for Atmospheric CHartographY) aboard ENVISAT (Environmental Satellite) are...
