The transcapillary fluid movement, induced by drinking a large amount of water, is known to lead to an increase in the extravascular fluid volume of tissues such as the muscle and the skin". The mechanism underlying this phenomenon, however, is poorly understood. The purpose of the present study was to know the nature and strength of the driving f orce which operates in such a fluid movement. T...

BACKGROUND In critically ill patients with acute kidney injury, estimates of kidney function are used to modify drug dosing, adjust nutritional therapy and provide dialytic support. However, estimating glomerular filtration rate is challenging due to fluctuations in kidney function, creatinine production and fluid balance. We hypothesized that commonly used glomerular filtration rate prediction...

In recent years, pathophysiology and clinical impact of microvascular fluid filtration has regained interest. As the latest data in surgical patients have been published almost 20 years ago, there is need for further research to better understand fluid filtration during the perioperative period. Venous congestion plethysmography (VCP) provides a rapid and noninvasive method, which has been show...

We studied the conditions necessary for optimal recovery of bacteria from cerebrospinal fluid. Our results indicated that Streptopcoccus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae can be quantitatively recovered in the sediment after centrifugation at 1,500 X g for 15 min. Equivalent numbers of bacteria were recovered by centrifugation or filtration of antibiotic-free cerebr...

A model is presented for enhancement of fluid flow through bone matrix and any porous tissue engineering scaffold implanted within it. The mechanism of enhancement is the skeletal muscle pump in compartments adjacent to the bone. Pressure waves from muscle pump contractions aided by increased blood pressure during exercise coupled with temporary occlusion of arteries leading to and veins from t...

introduction: the purpose of this laboratory study was to evaluate the effect of acidic ph on the sealing ability of calcium-enriched mixture (cem) cement and mineral trioxide aggregate (mta) apical plugs. methods and materials: seventy single-rooted human maxillary anterior teeth were recruited. the teeth were randomly divided into 4 experimental groups ( n =15), and 1 negative and 1 positive ...

Abstract This paper investigates MHD fluid flow and distribution of heat inside a filter chamber during process filtering particles from the fluid. A model viscous incompressible is studied to seek semi-analytical solutions which are analysed find dynamics that lead optimal outflow (maximum filtrates) filtration. Lie group method used reduce system four partial differential equations describing...

in this research, modeling of limiting flux in membrane filtration of skimmed milk as well as the results of simulation by matlab is presented. the presented model is actually a force balance approach and consists of drag, gravitational and lift forces, and forces between colloidal particles (electrostatic repulsive and van der waals attractive forces). to consider the back diffusion phenomenon...
