(Gram.) Di[ae]resis. See Di[ae]resis, 1.
(Rhet.) Same as Asyndeton.

(Chem.) The separation of different substances in solution, as crystalloids and colloids, by means of their unequal diffusion, especially through natural or artificial membranes.
Douglas Harper's Etymology Dictionary
1580s, from Latin, from Greek dialysis "dissolution, separation" (of the disbanding of troops, a divorce, etc.), from dialyein "dissolve, separate," from dia- "apart" + lyein "loosen" (see lose). Used originally in logic and grammar; chemistry sense is first recorded 1861, medicine 1914. Related: Dialytic.
n. 1 (context chemistry English) A method of separating molecules or particles of different sizes by differential diffusion through a semipermeable membrane. 2 (context medicine English) haemodialysis.
n. separation of substances in solution by means of their unequal diffusion through semipermeable membranes
[also: dialyses (pl)]
In medicine, '''dialysis ''' (from Greek διάλυσις, diàlysis, meaning dissolution, διά, dià, meaning through, and λύσις, lỳsis, meaning loosening or splitting) is a process for removing waste and excess water from the blood and is used primarily as an artificial replacement for lost kidney function in people with kidney failure. Dialysis may be used for those with an acute disturbance in kidney function ( acute kidney injury, previously acute renal failure) or progressive but chronically worsening kidney function—a state known as chronic kidney disease stage 5 (previously chronic renal failure or end-stage renal disease). The latter form may develop over months or years, but in contrast to acute kidney injury is not usually reversible and dialysis is regarded as a "holding measure" until a kidney transplant can be performed or sometimes as the only supportive measure in those for whom a transplant would be inappropriate.
The kidneys have an important role in maintaining health. When healthy, the kidneys maintain the body's internal equilibrium of water and minerals (sodium, potassium, chloride, calcium, phosphorus, magnesium, sulfate). The acidic metabolism end-products that the body cannot get rid of via respiration are also excreted through the kidneys. The kidneys also function as a part of the endocrine system, producing erythropoietin, calcitriol and renin. Erythropoietin is involved in the production of red blood cells and calcitriol plays a role in bone formation. Dialysis is an imperfect treatment to replace kidney function because it does not correct the compromised endocrine functions of the kidney. Dialysis treatments replace some of these functions through diffusion (waste removal) and ultrafiltration (fluid removal).
Dialysis is a common laboratory technique that operates on the same principle as medical dialysis. In the context of life science research, the most common application of dialysis is for the removal of unwanted small molecules such as salts, reducing agents, or dyes from larger macromolecules such as proteins, DNA, or polysaccharides. Dialysis is also commonly used for buffer exchange and drug binding studies.
Usage examples of "dialysis".
Given the stress of the dementia work-up, every organ system crumpled: in a domino progression the injection of radioactive dye for her brain scan shut down her kidneys, and the dye study of her kidneys overloaded her heart, and the medication for her heart made her vomit, which altered her electrolyte balance in a life-threatening way, which increased her dementia and shut down her bowel, which made her eligible for the bowel run, the cleanout for which dehydrated her and really shut down her tormented kidneys, which led to infection, the need for dialysis, and big-time complications of these big-time diseases.
