(a.) Pertaining to, derived from, or containing, osmium; specifically, designating those compounds in which it has a valence higher than in other lower compounds; as, osmic oxide.
Example Sentences:
(1) The results suggest that the conversion of the HRP-TMB reaction product to an electron-dense form during osmication is intimately associated with the pH of the phosphate buffer and the total time of osmication.
(2) In agreement with previous findings osmicated cat 'C'-terminals failed to reveal synaptic complexes in regions possessing the subsynaptic cistern ('cisternal regions').
(3) The epitopes recognized by these mAbs were adversely affected by these fixatives; therefore, pre-embedding immunogold staining was employed, prior to fixation, osmication, dehydration and embedding.
(4) Aldehyde-fixed tissues are cut into sections with an automatic sectioner, incubated cytochemically osmication if required, then embedded in epoxy resin between fluorocarbon coverglasses which are supported by a platform specially designed for this purpose.
(5) The only complaint from the patient, months after the osmic acid injection, was a strong metallic taste on the tongue.
(6) They were studied with the prolonged osmication technique.
(7) With the polygalacturonase--gold complex, differences in the labelling distribution were noted according to the fixation procedure indicating, therefore, that osmication of the tissues could greatly interfere with the localization of the specific enzyme binding sites.
(8) We speculate that either oxidative polymerization of DAPA or Schiff's base formation with protein after aldehyde formation is responsible for the latter reaction, which is made permanent for ultracytochemical localization by osmication at a later step.
(9) This model has been tested by tracing the profiles of vesicles within the PTA network and comparing their size and shape frequency distributions with those of osmicated synaptic vesicles.
(10) The lingual gingival and the alveolar mucosa of mandible of the house musk shrew (Suncus murinus) were stained by methylene blue vital staining or osmic acid staining, and mounted as whole thickness preparations.
(11) Various methods of dissection, fixation, osmication, sectioning and staining were tested in order to develop an acceptable technique for preparing 9, 10, 11, and 12-day-old rat otocysts for electron microscopic study.
(12) Eleven patients had never received osmic acid injections in this particular joint, whereas 18 had had such injections 1-24 months prior to surgery.
(13) The inferior medullary velum and tela choroidea were removed intact from the fourth ventricle, post-osmicated, dehydrated, critical point dried, coated with palladium-gold and examined in a Cambridge Stereoscan S4 scanning electron microscope.
(14) Thin 100-nm sections were then cut and stained from the osmicated blocks for ultrastructural studies.
(15) A category of large boutons forming synapses with the soma and proximal dendrites of spinal motoneurons was studied in glutaraldehyde-fixed, non-osmicated tissue stained with uranyl acetate and lead citrate.
(16) The "sebum" secretion was evaluated in caucasian, black, yellow and mullato people of different ages by the osmic acid technique utilizing a semi-quantitative scale of score ranging from 0 to 9 points.
(17) After 18 hours of growth on selective serum-agar medium C diphtheriae cultures with different toxicogenic activity, and also diphtheroid and Hoffmann's baccillus cultures were removed, washed of the remnants of the nutrient medium and fixed under cold conditions by two combined methods (with glutaric aldehyde-osmic acid--uranyl acetate, and potassium permeanganate--uranyl acetate).
(18) The organization of the granule is somewhat altered when osmication is omitted from the fixation procedure.
(19) Sequential treatments of osmicated specimens with tannic acid pH 7.0-9.0, and uranyl acetate, pH 4.1, enhanced the density of the elastin intensely, increased collagen staining moderately, but hardly increased the density of nuclei and microfibrils.
(20) The reaction product even at this stage prior to osmication is highly visible.
Osmious
Definition:
(a.) Denoting those compounds of osmium in which the element has a valence relatively lower than in the osmic compounds; as, osmious chloride.
