    Notes: Abstract Membrane vesicles from the malolactic bacterium Leuconostoc oenos were obtained by a modified version of the procedure of Kaback [Methods Enzymol 22:99–120 (1971)]. Protoplasts were produced at frequencies greater than 95% by a method entailing mutanolysis digestion and osmotic shock. Glycerol or polyethyleneglycol 600 was required as an osmotic stabilizer while the use of sucrose prevented closed vesicle formation during osmotic shock. The membrane vesicles retained their functional properties and accumulated l-malic acid in response to an ATPase-induced proton gradient across the membrane of ATP-loaded vesicles. l-Malate uptake was strongly inhibited by dicyclohexylcarbodiimide, a specific inhibitor of membrane-bound ATPase. These data support the possibility of a ΔpH-dependent transport of l-malate. Vesicles not loaded with ATP were slightly permeable to malic acid with an initial uptake rate (0.5 nmol·μl−1·s−1) similar to the diffusion rate obtained previously in a L. oenos malate-transport-deficient strain. These results confirm two simultaneous uptake mechanisms in L. oenos, a permease-mediated transport and a passive diffusion for the anionic and the undissociated forms of l-malic acid respectively.

    Notes: Résumé Les mesures de résonance paramagnétique électronique effectuées jusqu' à présent sur le muscle n'ont pas tenu compte de la différentiation de ce tissu en muscles blancs et rouges. Nous avons comparé les signaux du muscle blanc, du muscle cardiaque et de divers muscles rouges de carpe. Le muscle blanc présente une très faible intensité; le myocarde et différents muscles rouges donnent des valeurs plus élevées en accord avec leur plus grande teneur en mitochondries. Le muscle rouge de la ligne latérale se distingue toutefois des autres muscles rouges par un signal environ 2×plus intense dû, comme le montrent des examens histologiques, à la présence dans ce cas de mélanocytes situés le long de faisceaux conjonctifs et de capillaires sanguins.

    Notes: Abstract In 94 marble samples from 4 quarry districts in Italy (Carrara) and Turkey (Proconnesus, Dokimeion, Usak), minor and trace elements were determined by instrumental neutron activation analysis (INAA) and atomic absorption spectrometry (AAS). The maximum size of the calcite grains (MGS) of the rocks was measured in thin section. For 16 elements considered in this work, the concentration ranges show important inter-district overlaps; this also applies to the maximum grain size. However, the application of cluster analysis, using selected attributes, allows one to discriminate every pair of districts; 90 samples are classified correctly in all classification dendrograms.

    Description / Table of Contents: Eésumé. Une méthode d'étude du débit sanguin musculaire au cours même de l'exercice est décrite. Elle est basée sur la mesure de la disparition d'un traceur radioactif (Xénon 133) injecté au sein du tissu. La vascularisation du quadriceps est étudiée pendant des exercices à plusieurs intensités, sur bicyclette ergométrique. Le débit sanguin musculaire s'accroît proportionnellement à l'intensité de l'exercice. Pour 100 g de muscle, le débit sanguin passe de 13,3 à 39,1 ml/min lorsque la puissance de l'effort fourni est accrue de 50 à 250 watts. La reproductibilité d'une même mesure est satisfaisante: le coefficient de variation de 5 mesures répétées vaut 10 à 17%. Les causes d'erreurs de cette technique sont discutées; ses avantages sont mis en évidence.
    Notes: Summary A method for the measurement of the muscular blood flow during rhythmic exercise is presented. An external counter follows the clearance rate of a radioactif tracer (Xenon 133) injected into the tissu. The circulation in the quadriceps was measured for several workloads on a bicycle ergometer. It was found that the muscular blood flow increased proportionately to the intensity of muscular work. For 100 g of muscle, the blood flow rose from 13.3 to 39.1 ml/min when the workload increased from 50 to 250 watts. The reproductibility for the test was satisfactory; the coefficient of variation for 5 similar measures reached 10 to 17%. The causes of error from such a technique were discussed as well as the advantages.

    Notes: Abstract Physiological reactions during exercise were tested under hyperoxic and hyperbaric conditions. In 6 subjects walking and running at increasing speeds on a treadmill, maximum performance showed little change when the respired air was enriched with O2. Maximum metabolism, measured by CO2 production, increased by 3.2%. During exercise on a bicycle ergometer, maximum O2 uptake increased by 3% in 5 subjects breathing pure O2 at 1 ATA. During hyperoxia the maximum O2 consumption measured at 2 and 3 ATA did not differ significantly from that measured at 1 ATA. Heart rate showed highly comparable maximum values under the various experimental conditions. During submaximal exercise, heart rate was consistently lower when the subjects breathed O2. The O2-linked difference became slighter with every increase in work load. Under hyperbaric and hyperoxic conditions, ventilation was invariably reduced during exercise.
