Microtomy
Definition:
(n.) The art of using the microtome; investigation carried on with the microtome.
Example Sentences:

(17) This approach offers several advantages over existing techniques: 1) uniform section thickness is more easily obtained than with paraffin or cryostat microtomy, thereby allowing improved resolution and more reliable identification of mesenchymal cells with small nuclei such as skeletal muscle myocytes or fibroblasts, 2) the preparations are stable over long periods and can be repeatedly viewed or photographed, and 3) calcified tissues can be examined without prior decalcification.
(18) The volume of the heart was determined multiplying the cardiac profiles areas (evaluated by point counting planimetry on serial sections) by the thickness of microtomy.
(19) This study has been made possible by two technological advances, firstly the development of cryostat microtomy for cutting unfixed, undemineralised bone, and secondly the use of scanning and integrating microdensitometry for quantifying the activity in each periosteal cell.
Tissue
Definition:
(n.) A woven fabric.
(n.) A fine transparent silk stuff, used for veils, etc.; specifically, cloth interwoven with gold or silver threads, or embossed with figures.
(n.) One of the elementary materials or fibres, having a uniform structure and a specialized function, of which ordinary animals and plants are composed; a texture; as, epithelial tissue; connective tissue.
(n.) Fig.: Web; texture; complicated fabrication; connected series; as, a tissue of forgeries, or of falsehood.
(v. t.) To form tissue of; to interweave.
Example Sentences:
(1) In conclusion, the efficacy of free tissue transfer in the treatment of osteomyelitis is geared mainly at enabling the surgeon to perform a wide radical debridement of infected and nonviable soft tissue and bone.
(2) If ascorbic acid was omitted from the culture medium, the extensive new connective tissue matrix was not produced.
(3) The interaction of the antibody with both the bacterial and the tissue derived polysialic acids suggests that the conformational epitope critical for the interaction is formed by both classes of compounds.
(4) The Cavitron Ultrasonic Surgical Aspirator (CUSA) is a dissecting system that removes tissue by vibration, irrigation and suction; fluid and particulate matter from tumors are aspirated and subsquently deposited in a canister.
(5) Bilateral symmetric soft-tissue masses posterior to the glandular tissue with accompanying calcifications should suggest the diagnosis.
(6) In cardiac tissue the adenylate system is not a good indicator of the energy state of the mitochondrion, even when the concentrations of AMP and free cytosolic ADP are calculated from the adenylate kinase and creatine kinase equilibria.
(7) Spectrophotometric determination of the sulfhydryl content in the animal tissue before (control) and after using 6,6'-Dithiodinicotinic acid is applied.
(8) Microionophoretically applied excitatory amino acids induced firing of extracellularly recorded single units in a tissue slice preparation of the mouse cochlear nucleus, and the similarly applied antagonist 2-amino-5-phosphonovalerate (2APV) was demonstrated to be a selective N-methyl-D-aspartate (NMDA) receptor antagonist.
(9) The vascular endothelium is capable of regulating tissue perfusion by the release of endothelium-derived relaxing factor to modulate vasomotor tone of the resistance vasculature.
