(19) We have found that after the initial rise in scattering, there is a further gradual increase in scattering (we call it "super-opalescence").
(20) A fraction possibly corresponding to VHDL (very high density lipoproteins, 77% protein, 23% lipid) was also detected but appeared contaminated by a protein-rich opalescent material.
Turbidity
Definition:
(n.) Turbidness.
Example Sentences:
(1) There were found out one-sided relations for instance concerning the proportion of transaminases, thymol turbidity test as well as creatinine to the erythrocyte sedimentation rate.
(2) This paper describes the properties and use of a fiber optic probe as an attachment to a spectrophotometer and its use for measurements in solutions and turbid suspensions.
(3) Depriving the mutant of glucosamine resulted in a rapid loss of viability of the cells, followed by a decrease in the turbidity of the culture.
(4) This test is a rapid, inexpensive alternative to current 48- to 72-h methods in which broth turbidity is used as the end point.
(5) All phase II-contaminated TPN solutions showed visual turbidity after 96 hr, and all test organisms were recovered and identified.
(6) Continuous measurements were made of the turbidity of growing cultures of Escherichia coli, Streptococcus mutans, and Saccharomyces cerevisiae.
(7) However, the effects of temperature on the rate of assembly above 37 degrees C were opposite to the effects seen at temperatures below 37 degrees C. In the range of 37-41 degrees C, the turbidity propagation rate decreased markedly with temperature.
(8) In addition, control myosin synthetic thick filament length as well as turbidity in solution, measured by light scattering, were twice as large as those of the myopathic heart myosin.
(9) The turbidities are remarkably high when one considers the low concentrations of protein and nucleic acid materials that are used.
(10) It is therefore essential to take into consideration the pH and turbidity of the water before applying molluscicidal treatment.
(11) With increasing hydrostatic pressure, the turbidity of an alpha-crystallin solution increases exponentially to a plateau at about 6000-8000 psi; upon release of pressure, the samples slowly return to their original turbidity level.
(12) Turbidity curves, measured following addition of thrombin to purified fibrinogen Milano IV, both in presence of calcium or EDTA, were markedly delayed.
(13) The liposomal solubilization, which was monitored by turbidity measurements or by determination of phospholipid sedimentability, was accompanied by the formation of a phospholipid-protein complex similar or identical to the one we previously reported to be formed from sonicated liposomes of egg phosphatidylcholine (Scherphof, G., Roerdink, F., Waite, M. and Parks, J.
(14) The decrease in turbidity at 400 nm, resulting from the uptake of the micro-organisms by the neutrophils, was measured for 20-30 min and the area under the curves was taken as a measure of the opsonizing capacity of the serum or the phagocytic capacity of the neutrophils.
(15) After removal of the methyl ester on the side chain of Glu, these polymers exhibited a remarkable pH dependence of the temperature for their inverse temperature transitions, which are followed as turbidity development at 300 nm.
