(17) After examining the cases reported in literature (Sacks, Barabas, Beighton Sykes), they point out that, contrary to what is generally believed, the syndrome is not rare and cases, sporadic or familial, of recurrent episodes of spontaneous rupture of the intestine and large vessels or peripheral arteries are frequent.
(18) haematobium and is a complication of bilharziasis of the bladder and intestine.
(19) Cloacal exstrophy, centered on the maldevelopment of the primitive streak mesoderm and cloacal membrane, results in bladder and intestinal exstrophy, omphalocele, gender confusion, and hindgut deformity.
(20) One thousand nineteen Wyoming ground squirrels (Spermophilus elegans elegans) from 4 populations in southern Wyoming were examined for intestinal parasites.
Urobilin
Definition:
(n.) A yellow pigment identical with hydrobilirubin, abundant in the highly colored urine of fever, and also present in normal urine. See Urochrome.
Example Sentences:
(1) The microflora also influence the degradation of mucin, the conversion of urobilin to urobilinogen, of cholesterol to coprostanol, and the production of short chain fatty acids.
(2) The residual part of urobilinogen is further reduced to urobilin, stercobilin and dipyrrolmethenes and excreted in the faeces.
(3) These results point unambiguously to a urobilin structure with one vinyl and one ethyl beta-substituent.
(4) Isomeric forms of mesobiliviolin IXalpha and of i-urobilin IXalpha may also be formed.
(5) Chromic acid degradation of a d-urobilin, obtained after incubation of bilirubin in fecal bacterial cultures, gave methylvinylmaleimide and methylethylmaleimide.
(6) Measurements of the temperature dependence of the circular dichroism spectra of l-stercobilin and d-urobilin show that the conformations of these optically-active urobilinoids change with temperature between 163 and 297 degrees K. These conformational changes depend critically on the hydrogen bonding characteristics of the solvent.
(7) After oxidation of urobilinogen with iodine, the concentration of the resulting urobilin is directly determined from the absorption (or fluorescent) spectrum.
(8) High sensitivity and high specificity for the procedure result from the high value of absorption coefficient and by the characteristic absorption spectrum of zinc complex of urobilin, respectively.
(9) Serial estimations of SGOT and SGPT activity, urine tests for urobilin and bilirubin and haematological investigations were undertaken at frequent intervals.
(10) These results, coupled with those of earlier studies, also establish the absolute configuration of the (+)-urobilin 7 and of the phycobilin 8 at C-7'.
(11) These results indicate establishment of microbes capable of converting bilirubin to urobilins within the second year of life.
(12) This appears to be due to the interference of the large amounts of urobilin present in the urine of these patients.
(13) Previous methods to quantitate urobilinogen lack precision due to either incomplete reduction of urobilin or to losses of pigment before the use of Ehrlich's aldehyde reaction or due to pigment precipitation, as occurs in Schlesinger's fluorescent assay.
(14) i-Urobilin and 1-stercobilin were separated by high-performance liquid chromatography on a reversed-phase octadecylsilane-bonded column and detected fluorimetrically through formation of phosphor with zinc ions in the eluent.
