(a.) Reflecting a milky or pearly light from the interior; having an opaline play of colors.
Example Sentences:
(1) Among both exposed and non-exposed aged over 45, there were no significant differences with regard to the characteristics of lens opacities--prevalence (19 in the 21 exposed; 10 in the 16 non-exposed), distribution of the location, and importance and type (opalescence or discontinuous opacities).
(2) The severity of nuclear opalescence (NO), cortical (C) and posterior subcapular cataract (P) was graded in a masked fashion using the LOCS II standards.
(3) The rate of this reaction can be estimated roughly from the initial rate (Vo) of the accompanying turbidity increase ("super-opalescence") of the acto-S-1 solution.
(4) This may indicate that there is considerable variation in inheritance patterns for hereditary opalescent dentine and that this trait does not always exhibit 100 percent penetrance.
(5) Furthermore, selenite induced the gradual development of opalescence and the oxidation of sulfhydryl in the lens protein solution.
(6) At pH 1-7 the alpha-particles dissociated into their constituent beta-particles with a consequent decrease in the opalescence of the solution.
(7) A family is described in which two females are more severely affected by hereditary opalescent dentine than the males.
(8) Prednisolone-induced aggregates result in an opalescence in the crystallins solution which is reversed by the addition of dithiothreitol.
(9) Residual Triton X-100 was removed from the opalescent vesicle suspension by sucrose density gradient centrifugation and subsequent dialysis.
(10) Shortcomings in previous attempts have been corrected by objectively aligning a "blind" eye with the center of a translucent opalescent screen.
(11) A potential of 100 V was applied for 12 hours, then raised to 200 V for another 12 hours, and finally to 300 V until opalescence appeared at the bottom of the tube.
(12) Colonies of C. perfringens on LLA had typical opalescent zones, a distinctive feature that can aid in presumptive identification.
(13) The presence of the regulatory light chain did not affect hyper-opalescence (or super-opalescence), since there were no significant differences between papain S-1 and chymotryptic S-1 with respect to these phenomena.
(14) We conclude that the most likely mechanism responsible for the zones is a light-scattering effect caused by antibodies attached to the viral surface and that the quality of the opalescence to some extent seems to be dependent on the Fc-fragment.
(15) High activity of MPO was found for retina and lens of healthy men and elderly people with lens opalescence.
(16) The oviposition-stimulating factor was localized in the opalescent gland of the male accessory gland and was transferred to the female via the spermatophore during copulation.
(17) Adjacent filaments in the bundles had a distance of approximately 180 A. Hyper-opalescence occurred at r approximately equal to 1 when KCOOCH3 was used instead of KCl.
(18) Impairment of catalytic efficiency can only be documented in opalescent test solutions in which the insecticides are present in excess of their solubility limit.
(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.
Opaline
Definition:
(a.) Of, pertaining to, or like, opal in appearance; having changeable colors like those of the opal.
Example Sentences:
(1) Ink and opaline are ejected by a series of coordinated pumping movements of the mantle, gill, and parapodia that closely resemble triggered 'respiratory pumping' or 'Interneuron II' episodes (Kupfermann and Kandel 1969; Byrne and Koester 1978; Hening 1982).
(2) Opaline silica deposits are formed by many vascular (higher) plants.
(3) Pastel mink were intermediate to the opalines, and dark mink indicative of strain differences in the genetic control of gonadal histamine synthesis and inactivation.
(4) Ink and opaline ejections are directed to the front or back of the animal by characteristic responses of the siphon, mantle, and parapodia.
(5) During the years 1970, 1971 and 1972, the irregular antibodies were systematically screened in Toulouse on all blood donors with a manual technique on opaline plate using enzyme treated red cell tests (papain).
(6) Testicular histamine content was higher in December (the time of sexual quiescence) that in March (breeding time) in opaline mink.
(7) The defensive secretions, ink and opaline, are directed along the anterior-posterior axis at the source of noxious stimulation.
