Dictionary » D » Dialysis
Separation of substances in solution by means of their unequal diffusion through semipermeable membranes.
Dialysis is the separation of small solute molecules or ions (e.g., glucose, Na+, Cl-) from macromolecules (e.g., starch) by virtue of their differing rates of diffusion through a differentially permeable membrane.
Dialysis a method for separating molecules of different sizes by diffusion through a partially permeable membrane.
Dicotyledon a flowering plant that produces seeds with two cotyledons.
Which of the following organelles do not contain a double-membrane?
People with malfunctioning kidneys often have to go through a process called dialysis where they are hooked up to a machine that filters their blood.
insufficient to eliminate wastes and regulate the composition of blood. Such a condition is always fatal within a few weeks unless the underlying cause is corrected, a new kidney is transplanted, or the blood is artificially cleared by dialysis ...
The assembly mixtures were then transferred to a 96-well microdialysis device (Spectrum Laboratories).
A dialysis machine which is used for people with kidney failure cannot differentiate between the useful and toxic molecules in the blood filtrate.
The cell membrane, along with such things as dialysis tubing and cellulose acetate sausage casing, is such a membrane. The presence of a solute decreases the water potential of a substance.
A particular concern is the contamination of medical devices such as urinary catheters, hemodialysis equipment, and medical and dental implants. Biofilms that develop on these devices can increase the risk of patient infection.
An equal amount of this paste was added to a solution of protein and to a solution of starch in separate dialysis tubing. The dialysis tubing was left in separate beakers of water for two hours.
Infection, environmental toxins such as mercury, and genetic disease can have devastating results by causing disruption of kidney function. Many kidney problems can be treated by dialysis, where a machine acts as a kidney.
And that's because water has the ability to go through a number of different membranes. This black line here that I drew in I'm using it to represent some kind of membrane. Well it's a cell membrane, a special kind of plastic or dialysis tube ...
