    Notes: Résumé On a séparé le tissu intestinal en muqueuse et muscle, lesquels ont été incubés in vitro dans une solution d'acide aminé marqué; ainsi on a pu étudier l'absorption intracellulaire de l'acide aminé. On a trouvé que la musculature intestinale ne peut accumuler un acide aminé contre un gradient de concentration. Il semble qu'il existe dans le muscle une barrière contre la diffusion dont la significance est discutée.

    Notes: Résumé En présence de sodium, l'activité totale de la NADH-cytochrome c réductase rénale était doublée; le potassium induit le même effet stimulateur. Cette enzyme sensible aux cations n'est inhibéc ni par la roténone ni par l'antimycine. Elle était également insensible à l'ouabaïne et à l'acide éthacrynique. Des expériences destinées à révéler sa localisation cytologique n'ont que partiellement réussi: l'enzyme ne semble pas être associée a la membrane de la bordure en brosse, ni à la membrane péritubulaire. Ces résultats suggèrent qu'elle n'est pas impliquée dans les mécanismes des pompes à sodium.

    Notes: Résumé On a étudié I'influence de la pression hydrostatique intraluminale sur l'absorption d'eau, d'électrolytes et de glucose dans une anse perfusée d'iléon de chien in vivo. Une augmentation de la pression de 0 à 10 cm d'eau provoque une stimulation considérable de I'absorption isotonique. Un plateau est atteint à 20 cm d'eau, mais même après une perfusion à 30 cm d'eau, la muqueuse n'est pas lésée. Ces résultats suggèrent qu'il faut contrôler strictement les conditions de perfusion dans des expériences in vivo.

    Notes: Summary Glucose inhibits the accumulation ofl-phenylalanine by rat intestinal slices during 45-minute incubations. In the presence of DNP (which alone abolishes all active transport), glucose, but not galactose, significantly stimulates amino-acid uptake. However, during short incubations, glucose inhibits the entry of phenylalamine into the tissue, both in the presence and absence of DNP.

    Notes: Abstract A detailed methodology is described for fluorescence-activated cell sorting (FACS) of porcine muscle cells that have been transfected to express green fluorescent protein (GFP). Cells are liberated from porcine skeletal muscle and primary cultures are transfected with DNA encoding GFP. Primary cultures are subjected to immunocytochemistry using a primary muscle-specific monoclonal antibody followed by incubation with a phycoerythrin-conjugated second antibody. Transfected myoblasts aresorted from fibroblasts using forward angle light scatter and ninety degree light scatter, phycoerythrin fluorescence, and GFP fluorescence. These procedures allow for isolation of genetically-engineered porcine muscle cells more rapidly than traditional clonal selection procedures. Consequently, FACS provides porcine myoblast populations that retain the majority of their replicative capacity and are not contaminated with non-myogenic cells.

    Description / Table of Contents: Zusammenfassung Betrachtet man ein 3-Phasen-System, in welchem ein Tropfen der Phase 1 sich der Grenzfläche zwischen Phase 2 und Phase 3 nähert, so sieht man, daß, falls die Dichte der Phasen verschieden ist, der unter dem Tropfen abfließende Film nicht kugelförmig ist. Die Dimensionen des Tropfens wurden theoretisch vorausgesagt, indem der Tropfen in einen oberen und einen hängenden Teil aufgeteilt wurde. Diese Dimensionen stimmen sowohl mit den in einem System experimentell erhaltenen Werten überein als auch für den Fall, daß ein oberflächenaktiver Stoff im abfließenden Film vorhanden ist, unter der Annahme, daß die Grenzflächenspannung ihren minimalen Gleichgewichtswert erreicht. Reißt der aus Phase 2 bestehende abfließende Film, so kann der Tropfen an der Grenzfläche verweilen oder direkt durch sie hindurchtreten, je nach Größe des Auftriebs und der Grenzflächenkräfte. Tritt der Tropfen direkt durch die Grenzfläche in die Phase 3, so wird er gänzlich durch einen Film der Phase 2 umgeben. Reißt dieser Film, so kehrt ein kleiner Tropfen der Phase 2 zur Grenzfläche zurück.
    Notes: Summary In a three phase system the shape of the draining film beneath a liquid drop of phase 1 approaching a deformable liquid-liquid interface between phases 2 and 3 is not spherical when the densities of the phases differ. The drop dimensions have been predicted theoretically by splitting the drop into a sessile part and a pendant part. These dimensions agree with those experimentally obtained for a pure system and also when surface active agent is present in the draining film if the interfacial tension is assumed to approach its minimum equilibrium value. After rupture of the draining film of phase 2 the drop may remain at the interface or pass through it depending on the magnitude of the bouyancy and interfacial forces. Alternatively the drop may pass straight through the interface into phase 3 and become completely enveloped by a film of phase 2; when this finally ruptures a small drop of phase 2 returns to the interface.

    Notes: Abstract In the past 25 years, several approaches have been made to the theoretical study of thermal expansion of composites. These approaches range from the empirical, to sophisticated analyses based on applied mechanics. The alternatives are discussed in the following paper, after which the available experimental data are examined in the light of current theory. The approach of Kerner and similar workers shows reasonable success for those systems where the dispersed particles can be treated as spheres, but this case is of limited technological interest. On the other hand, the equation due to Turner most closely represents those systems in which the fillers are fibrous or plate-like in nature. Apart from particle shape, it appears that any general theory must take into account a number of physicochemical variables which have hitherto been omitted. Attention is drawn to the possible relationship which exists between bulk modulus or Young's modulus, and thermal expansion. This has been pointed out earlier by Barker.

    Keywords: BARE-1 retrotransposon Barley Net blotch resistance Linkage mapping Quantitative trait locus (QTL)
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract. Net blotch, which is caused by the fungus Pyrenophora teres Drechs. f. teres Smedeg., presents a serious problem for barley production worldwide, and the identification and deployment of sources of resistance to it are key objectives for many breeders. Here, we report the identification of a major resistance gene, accounting for 65% of the response variation, in a cross between the resistant line CI9819 and the susceptible cv. Rolfi. The resistance gene was mapped to chromosome 6H with the aid of two recently developed systems of retrotransposon-based molecular markers, REMAP and IRAP. A total of 239 BARE-1 and Sukkula retrotransposon markers were mapped in the cross, and the 30-cM segment containing the locus with significant resistance effect contained 26 of the markers. The type and local density of the markers should facilitate future map-based cloning of the resistance gene as well as manipulation of the resistance through backcross breeding.
