Protein
Definition:
(n.) A body now known as alkali albumin, but originally considered to be the basis of all albuminous substances, whence its name.

(16) We also show that the gene of the main capsid protein is expressed from its own promoter in an Escherichia coli strain.
(17) Western blot analysis of these mitochondria using an antibody against carnitine palmitoyltransferase II purified from beef heart demonstrates a 68-kDa protein, which under ischemic conditions apparently is decreased by 2 kDa.
(18) Fifteen sera ICA-IgG and ICA-protein A positive with high titres remained positive thereafter.
(19) Patient or fetal cord serum is commonly used as a protein supplement to culture media used in in-vitro fertilization (IVF).
(20) Using the oocyte system to express size-fractionated mRNA, we have also determined that the mRNA coding for this protein is between 1.9-2.4 kilobases in length.
Scleroprotein
Definition:
Example Sentences:
(1) In addition, the total sugars and the soluble non-scleroproteins were found to be increased in varicose samples.
(2) Proportions of elastin and collagen relative to dry weight increased markedly only between 4 and 2 weeks of age and not thereafter despite continuing rapid growth, steadily increasing medial tension, and increasing total scleroprotein content.
(3) The contributions of the relative radius, relative wall thickness, incremental strain, incremental elastic modulus, and medial scleroprotein content to the static elastic properties of the rat aortic wall have been examined in three groups of rats.
(4) It has been shown by X-ray diffraction and chiroptic spectroscopy that the glycosaminoglycans in connective tissue develop a helical structure; this induces the coordination of polycations and scleroproteins in their environment polycations and promotes or inhibites fibrillary aggregation.
(5) The authors examined neosynthesis of fiber proteins (scleroproteins) in the aorta of rats with genetic hypertonia and with experimental atherosclerosis after application of 3H-proline and 3H-lysine and subsequent determination of radioactivity of collagenous and elastic in the aortic wall.
(6) The clinical picture, the outcome of lymphocyte stimulation tests against S antigen (retina soluble antigen), outer rod segment, and scleroprotein, and the successful administration of corticosteroids after a partial spontaneous hearing improvement, are suggestive of an autoimmune disease.
(7) The importance of lipids in collagen formation was corroborated: by accumulation of lipids, which preceded the hydroxyproline increase (scleroproteins, collagen), by development of the proliferative-cellular reaction together with the higher phospholipid-hydroxyproline level as compared with control, by formation of earlier sclerosis of silicotic nodes in "condensed" silicosis with the simultaneous increase in absolute content of phospholipids and total lipids.
(8) Thus, medial cells were capable of adapting their quantitative scleroprotein synthetic response to differences in medial tension throughout growth but established a fixed qualitative response within 2 weeks.
(9) When expressed as absolute rates of protein synthesis, these scleroproteins were maximally expressed in the first 3 postnatal weeks.
(10) Elastin and collagen are the principal scleroproteins of the aortic wall, and they largely determine its physical and mechanical properties.
(11) The intracellular and extracellular phases of this process were similar to those of other scleroprotein-synthesizing cells.
(12) This role of lipids was also supported by the observed correlation between the absolute contents of scleroproteins and lipids within all steps of "quartz" silicosis development.
(13) Identical in size, weight, and composition at birth, the vessels maintained similar lengths and diameters at each age but diverged markedly in weight and scleroprotein content after 1 week.
(14) The cell elements are invariably endowed with a large microbrillary cytoplasmic brush, apparently made up of scleroproteins and showing the usual ultrastructural characteristics associated with low metabolic activity.
(15) medial thickening, scleroprotein increase) which have pathological effects.
(16) The results of this study indicate that, of the three cell types of the glomerulus, the epithelial cells (=podocytes) synthesize the proline-rich scleroproteins of the glomerular basement membrane.
(17) Otherwise the pattern of the enzymatic hydrolysis was investigated by measuring the hydroxyproline content, and so the collagen content using the 7.46 conversion factor from hydroxyproline to the scleroprotein collagen, in the various steps of the hydrolysis itself: the analytical results showed no differences between the freeze-dried collagen and the gelified form; this confirms that the lyophilization process does not alter the polypeptidic composition of the collagen in any way.
