(a.) Having elevations or depressions in form like one half of a bivalve shell; -- applied principally to a surface produced by fracture.
Example Sentences:
(1) Those differences can be summarized as follows: (1) the occurrence of pronounced, highly curved hackle marks, which could in many instances be mistaken for conchoidal marks;(2)the appearance of the beveled edges bordering the cratering on the side opposite origin of force; and (3) a more apparent tendency toward an inverse relationship of muzzle velocity and energy to radial fracture length and degree of curving along crater boundaries.
(2) These figures were assumed to be the very early stage of formation of conchoidal bodies at the LM level, so-called Schaumann bodies.
(3) Their similitude with other reported intracellular calcareous bodies occurring in malakoplakia, infectious orchitis (Michaelis-Guttman' bodies or calcosphaerites), in beryllium granulomas (conchoid bodies) and sarcoidosis (Schaumann bodies) is discussed.
(4) Sclerotic granulomas with giant cells, conchoidal bodies, iron deposition in the pulmonary stroma--all these lung alterations allowed one to establish a diagnosis of lung berylliosis.
(5) Several patterns of calcification were noted including bubbly, plate-like, elongate, and conchoidal forms.
(6) Lung biopsies in the index cases revealed an interstitial infiltration of inflammatory cells and aggregates of conchoid bodies surrounded by multinucleated giant cells.
Planar
Definition:
Example Sentences:
(1) By means of rapid planar Hill type antimony-bismuth thermophiles the initial heat liberated by papillary muscles was measured synchronously with developed tension for control (C), pressure-overload (GOP), and hypothyrotic (PTU) rat myocardium (chronic experiments) and after application of 10(-6) M isoproterenol or 200 10(-6) M UDCG-115.
(2) This is due to the fact that the SPECT images contain more anatomical and physiological information than similar planar images.
(3) The planar 7H-pyridocarbazole cations form stacks approximately parallel to b. Interactions between stacks occur by weak van der Waals forces.
(4) The permeability properties of planar lipid bilayers made from egg lecithin, n-decane and a long-chain secondary amine (n-lauryl [trialkylmethyl]amine) are described.
(5) The results of quantitative analysis of planar thallium-201 stress scintigraphy are superior to those of visual analysis.
(6) In a direct test of the hypothesis that the M2 coat protein of influenza A can function as a proton translocator, we incorporated a synthetic peptide containing its putative transmembrane domain into voltage-clamped planar lipid bilayers.
(7) Qualitative planar 201-thallium (201Tl) scans, coronary angiography, or both were also performed (median between studies 11 days).
(8) In addition to improved image quality, the characteristics of 99mTc sestamibi allow gated planar or SPECT perfusion images to be obtained.
(9) The channel protein most likely is composed of several copies of a single type of polypeptide, which can be removed from photoreceptor membranes by detergents and functionally reincorporated into the membrane of liposomes or planar bilayers.
(10) Image quality was excellent and superior to that obtained from planar and tomographic MIBG studies.
(11) Nomograms for square planar arrays spanning the range from 3 X 3 cm to 10 X 10 cm were developed.
(12) Partial deviation from total planarity as in enol-carbamates (V) leads to some loss of binding affinity, which largely disappears in hydroaromatic structures (VI).
(13) Only 1.3% SLS reduced the rate of epithelial healing after three times a day drop application as determined using planar measures of epithelial regrowth.
(14) A recently developed rf echo planar imaging method has been modified to rapidly generate spectroscopic information along one in-plane axis and spatial information along the other.
(15) The adenine moiety is nearly planar and the torsional angle of the glycosidic linkage O(4')-C(1')-N(3)-C(4) is -161.5 degrees.
(16) Planar RBC imaging followed by blood-pool SPECT scanning was performed in 77 patients with a total of 108 hemangiomas and in 29 patients with a total of 46 hepatocellular carcinomas.
(17) The allene oxide also opens to a zwitterion, which undergoes charge delocalization to form a planar intermediate; this structure is the achiral precursor of the stable end product of pericyclic ring closure, viz., racemic cis-12-oxo-PDA.
(18) Data-analysis programs provide reproduction of stored data, comparison of linear scans, beam profiles along any line of a planar or volume scan, and isodose distributions from any planar scan or from any planar scan or from any plane of a volume scan.
(19) Planar scintigraphy showed an intense, diffuse biventricular uptake of the radiotracer.
(20) The power dependence of the pore formation rate on the toxin concentration in planar bilayers indicates that an aggregation mechanism underlies the channel assembly.
