(1) Pyrimidine osmate ester moieties, L2OSO4-pyrimidine, were formed.
(2) Similarly, Os(VI) was detected for the known cholesterol-osmate ester prepared and purified chemically.
(3) When the glass-fibre papers containing the digitonin cholesterol-ester-osmate complexes were stored in distilled water after fixation, the fluid became turbid.
(4) Os(VI) and Os(IV) could be present as osmate esters and osmium dioxide, respectively; Os(III) could be present as an oxo- or amino complex(es).
(5) Because of the extensive secondary and tertiary olfactory projections to the limbic forebrain and hypothalamus, and because most laboratory mammals are macro-osmatic, the nature and degree of olfactory control should be an important consideration in studies on the neural basis of social behavior.
(6) Therefore, and based on indexation methods, ZnOsO4 was found to be the formula of the ZIO mixture reduction; this zinc osmate has an orthorhombic crystalline lattice.
(7) This epoxide was efficiently cleaved to 6 beta, 7 alpha-dihydroxy-6,7-dihydrocanrenone by perchloric acid in a dioxane-water mixture; 6 beta, 7 beta- and 6 alpha, 7 alpha-dihydrocanrenone were obtained by OsO4 oxidation of canrenone in either-pyridine and subsequent reduction of the osmates by hydrogen sulfide.
(8) The osmium complex binds as a cis osmate ester to the C(5)-C(6) bond of the methylated pyrimidine in a fashion which is expected to be similar to the binding of the complex to thymidine residues in nucleic acids.
(9) Differences in diatrizoate concentration which existed between cortical and medullary zones in healthy kidneys at low dises were progressively eliminated as dosage increased, consistent with the osmatic fiutryiv rggrvy of diatrizoate.
(10) We also report syntheses of osmate esters of IPA in which the osmium is bonded through the 2'-and 3'-hydroxyl groups of the ribose residue.
(11) Drugs to be injected include steroids, aiming at anti-inflammation and analgesia, and radioisotope and osmate, aiming at synovectomy.
(12) Methanol solutions of dipotassium tetramethyl osmate (DTMO) have been found to be useful as general stains in electron microscopic studies of plant and fungal ultrastructure.
(13) Although generally similar in staining to lead citrate stains, some elements of cell ultrastructure appear different with dipotassium tetramethyl osmate staining, particularly the outer cell walls of fungi.
(14) It is likely that OsO4 alone, used as fixative in cytology might be due to the formation of metallic osmates (e.g., divalent osmates like CaOsO4).
Osmite
Definition:
(n.) A salt of osmious acid.
Example Sentences:
(1) A- and I-bands do not develop before the 38th osmite stage.
(2) The reabsorption of the osmitic equivalent of water has the effect of concentrating NaCl in the tubular fluid.
