    Notes: Stocks of Entamoeba histolytica grown in a monoxenic culture system from the feces of nonhuman primates are compared with the eleven zymodemes of E. histolytica so far demonstrated from man. In a similar fashion, Entamoeba chattoni has also been grown and identified. Both E. histolytica and E. chattoni have been demonstrated in keepers of the primate collections. Comparisons have been made using the electrophoretic patterns of three enzymes: glucosephosphate isomerase [(GPI) E.C.5.3.1.9], phosphoglucomutase [(PGM) E.C.2.7.5.1], and L-malate—NADP+ oxidoreductase (oxaloacetate-decarboxylating) [(ME) E.C. 1.1.1.40]. Enzyme patterns of E. histolytica from the apes were found to be identical with three of those already demonstrated from man. The enzyme pattern of E. chattoni was distinctly different from that of any of the E. histolytica zymodemes. Other protozoa found in the single fecal sample examined from each subject are also listed.

    The microscopic anatomy of the oesophagus, stomach and intestine of the channel catfish, Ictalurus punctatus (1979)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 14 (1979), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: An anatomical study of the digestive tract of the channel catfish revealed that the oesophageal mucosa was longitudinally folded and that secondary folds were occasionally located on the primary longitudinal folds. The infoldings were more numerous near the stomach. The stratified squamous epithelium covering the folds was made up of a basal layer, large mucous cells and simple squamous cells on the surface. The epithelium on the side of the folds consisted primarily of mucous secreting cells. Taste buds were observed between mucous cells on the apical portion of the oesophageal folds and were more prevalent in the cranial part of the oesophagus. The remaining layers of the oesophagus were: a lamina propria-submucosa, tunica muscularis and adventitia or serosa.The J-shaped stomach had two regions: a large sac-shaped region containing gastric glands and a smaller, nonglandular pyloric region. The large rugae of the stomach became gradually smaller near the pylorus. There was a well developed pyloric sphincter. The mucosa included a simple columnar epithelium, a lamina propria and adventitia or serosa.The intestine could be differentiated into a thick ascending segment, a descending segment, a thin convoluted segment and a thicker terminal segment, the rectum. Many mucosal folds containing branched villi characterized the ascending segment of the intestine. The descending and convoluted segments contained fewer folds with shorter and less-branching villi and were smaller in diameter and thinner walled. Descending and convoluted segments were also mildly convoluted and accounted for 80% of the total length of the intestine. An intestinal valve with a sphincter marked the beginning of the rectum. There was an approximately four-fold increase in the thickness of the tunica muscularis of the terminal segment of the intestine.

    Notes: [Auszug] The N-terminal tetradecapeptide sequence 1 (Table 1) of equine angiotensinogen was elucidated by Skeggs et al.8. The smallest fragment of 1 still hydrolysed by renin at a significant rate is the (6-13)octapeptide 2, although this cleavage is slow enough to allow 2 to function as a weak (IC50 = 200 ...

    Notes: [Auszug] Unlike bacteria, Mycoplasma have no rigid cell wall and are difficult to detect in heat fixed smears. The morphology can be preserved when less traumatic methods of fixation are used, and it occurred to us that it might be possible, if enough of the organisms were present, to see mycoplasmas in ...

    On the interpretation of data from Converging Flow Rheometers (1989)
    Springer
    Rheologica acta 28 (1989), S. 215-222 
    Details
    ISSN: 1435-1528
    Keywords: Converging flow rheometer ; planar extensional viscosity ; polymer solutions
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Physics
    Notes: Abstract A reappraisal of data obtained from a Converging Flow Rheometer (CFR) is presented, together with new results for a specific polymer solution. Particular emphasis is placed on the interpretation of the experimental pressure data in terms of a planar extensional viscosity. It is suggested that previous interpretations, while yielding viscosity levels that appear reasonable, nevertheless fail to give the qualitative behaviour that might be expected on the basis of predictions from well accepted constitutive models. This, in the authors' opinions, arises because certain fluids, i.e. those that are highly tension-thickening, cease to flow in accordance with the assumed kinematics at high flow rates. By adapting a recently proposed approximate analysis for flow through a contraction it is shown that better qualitative behaviour, for the planar extensional viscosity, can be obtained from the Converging Flow Rheometer.

    On the extensional viscosity of mobile polymer solutions (1987)
    Springer
    Rheologica acta 26 (1987), S. 20-30 
    Details
    ISSN: 1435-1528
    Keywords: Extensional viscosity ; polymer solution ; Spin Line Rheometer ; Converging Flow Rheometer ; Trouton ratio
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Physics
    Notes: Abstract We describe experimental results on the extensional viscosity of mobile polymer solutions obtained from two instruments, the first being a commercial Spin Line Rheometer and the second a custom-built lubricated-die Converging Flow Rheometer. The interpretation of data in terms of Trouton ratios is facilitated by a simple analysis for the Generalized Newtonian Fluid model. Agreement between data from the two rheometers is satisfactory and we show that polymer solutions can be either tension stiffening or tension thinning. However, the Trouton ratios in both cases are greater than the Newtonian values and we anticipate that this will always be the case for polymer solutions.
