What's the difference between dialyzer and filtration?
Dialyzer
Definition:
(n.) The instrument or medium used to effect chemical dialysis.
Example Sentences:

(6) The inhibitor is a very small, dialyzable compound which inhibits not only the R. rubrum but also the E. coli protein-synthesizing activity in vitro, whereas the activator is a non-dialyzable, small RNA molecule capable of stimulating only the R. rubrum activity.
(7) Polymethacrylate coated charcoal was inserted in the dialysis circuit before the dialyzer.
(8) It is also susceptible to thermal inactivation at 37 degrees , possibly through changes in the affinity of triiodothyronine to the nuclear binding protein(s), since the bound triiodothyronine becomes more readily dialyzable, is absorbed by an anion exchange resin, but retains its characteristic mobility on electrophoresis.
(9) With the growing number of dialyzed patients, secondary (sHPT) and tertiary hyperparathyroidism (tHPT) are assuming increasing importance.

(11) When samples at pH 3.5 were dialyzed against 0.1 M ammonium acetate (pH 6.9) to refold interferon gamma, the samples that contained NaCl in acid formed aggregates upon dialysis while those without NaCl formed a dimer apparently identical with the starting protein (i.e., before acid treatment).
(12) The dialyzability of iohexol was examined in patients with chronic renal failure on long-term hemodialysis treatment.
(13) A review of the literature indicated that out of 1087 patients reported, 72 patients were on the combination of an AN69 dialyzer and ACE inhibitor therapy and 41 (57%) demonstrated AR.
(14) The HD procedure was performed by the use of the cuprophan dialyze (Gambro).
(15) Plasma C3a des arg values increased markedly in the dialyzer outflow blood with the three dialyzer configurations.
(16) The addition of Mg2+ to the dialyzing solution resulted in the formation of short intermediate-sized filaments even at 4 degrees C. Further dialysis of the short intermediate-sized filaments against reassembly solution containing both NaCl and MgCl2 at 37 degrees C failed to elongate them into longer filaments, suggesting that annealing does not contribute to the elongation of neurofilaments.
(17) This C3 coating could be entirely abolished (without reducing C4 coating) by using Mg++ poor serum produced by dialyzing serum against Mg++ free barbital buffer.
(18) However, a substantial percentage of the enzyme activity could be recovered when the inactivated enzyme was dialyzed against a nitrogen buffer [e.g., tris(hydroxymethyl)aminomethane (Tris)].
(19) Bone mass and bone mineral content were measured in non-dialyzed and dialyzed uremic patients.
(20) The data suggest the presence of an excess of dialyzable, active sodium transport stimulating plasma factor(s) with relative molecular mass below 1000 Da.
Filtration
Definition:
(n.) The act or process of filtering; the mechanical separation of a liquid from the undissolved particles floating in it.
Example Sentences:
(1) Gel filtration of the 40,000 rpm supernatant fraction of a homogenate of rat cerebral cortex on a Sepharose 6B column yielded two fractions: fraction II with the "Ca(2+) plus Mg(2+)-dependent" phosphodiesterase activity and fraction III containing its modulator.
(2) In this review, we demonstrate that serum creatinine does not provide an adequate estimate of glomerular filtration rate (GFR), and contrary to recent teachings, that the slope of the reciprocal of serum creatinine vs time does not permit an accurate assessment of the rate of progression of renal disease.
(3) The enzyme was solubilized by Triton X-100 and purified approximately 480-fold by gel filtration and affinity chromatography on alanine methyl ketone-AH-Sepharose 4B.
(4) The authors conclude that H. pylori alone causes little or no effect on an intact gastric mucosa in the rat, that either intact organisms or bacteria-free filtrates cause similar prolongation and delayed healing of pre-existing ulcers with active chronic inflammation, and that the presence of predisposing factors leading to disruption of gastric mucosal integrity may be required for the H. pylori enhancement of inflammation and tissue damage in the stomach.
(5) The molecular weight of antigen RFB2 was estimated to be approximately 85,000 daltons based on the results of gel filtration on Sepharose CL-6B.
(6) Further purification of ZAB by filtration through Sephadex G-100 gave a preparation (ZAB2) which contained the common antigen as shown by the cross-reactivity of anti-ZAB2 rat serum with seven stains of N. gonorrhoeae.
(7) The flow properties of white cells were tested after myocardial infarction, by measuring the filtration rates of cell suspensions through 8 microns pore filters.
(8) Slight cross-reactivity was apparent when crude preparations of cellular or culture filtrate antigens, used in this laboratory to detect antibodies to Candida albicans, Coccidioides immitis and Cryptococcus neoformans, were probed with hyperimmune rabbit antisera to A. fumigatus.
(9) The culture filtrate and OM preparation were capable of inhibiting the chemotaxis of PMNL in response to the chemotactic factors of E. coli but LPS of B. fragilis was not able to do so.
(10) The enzyme from rat lung was purified about 30-fold by pH treatment (NH4)2SO4 fractionation, and gel filtration.

(13) Even though the administration of demethylchlortetracycline did not produce significant decreases in the glomerular filtration rate or renal blood flow in our patient, it is advisable to control the renal function in individuals treated with this drug since it may on occasion determine renal insufficiency.
(14) The fucose-labeled glycoproteins were converted to glycopeptides by pronase digestion and separated into two major classes by gel filtration on Sephadex-G-50.
(15) Receptors solubilized with Triton X-100 eluted in gel filtration as a major peak of Mr = 330,000 and retained high affinity binding (KD = 0.25 nM).
(16) It is inferred that in this experimental model (1) high-density lipoproteins are probably excreted in the glomerular filtrate, (2) alterations in the composition of the excreted lipoproteins may occur during their passage through the nephron.
