    RESULTS OF SURFACE REFLECTION SEISMIC MEASUREMENTS IN THE SIDERITE DISTRICT OF THE SIEGERLAND (1959)

    Notes: The iron ores of the Siegerland-district are found in lodes occurring in schists of Lower Devonian age. In the course of the geophysical exploration for these ores, an attempt was also made to clarify the structure and the tectonics of the substratum of the sedimentary rock formations by seismic reflection measurements from the surface. Reflections were recorded in great numbers from layers of Silurian and Devonian age. The form of the folding of the strata derived therefrom corresponds well with that deduced from geological investigations. Beyond that, correlatable reflections were recorded from horizons down to a depth of nearly 25 000 m. It turned out that the iron ore lodes known from the mine workings occur almost vertically above those places where greater dislocations appear in the deepest substratum, and which geologically could be interpreted as fracture zones. The results so far obtained seem to be indicative of the fact that the tectonics of the deepest substratum and the occurrence of ore deposits are related to each other.

    Notes: The iron ores of the Siegerland district are found in lodes occurring in schists of Lower Devonian age. These lodes, normally dipping almost perpendicularly, could be traced only by seismic reflection measurements underground, up to distances of approximately 500 m. The geophones were attached to the walls of the galleries. The frequencies of the recorded longitudinal and transverse waves ranged from 200 to 500 c.p.s. By this method a new siderite lode was discovered.

    IONIC, pH, AND TEMPERATURE EFFECTS ON THE BINDING ABILITY OF MYOSIN (1979)

    Notes: The peak force required to separate pieces of meat at a binding junction was measured with the Instron Universal Testing Machine. These measurements were used to study the effects of salt, phosphate, pH, cooking temperature and. protein concentration on the ability of crude myosin to bind meat pieces. Results showed salt and phosphate to linearly increase the ability of myosin to bind meat pieces primarily by solubilizing the protein. Temperature and the level of protein had increasing effects on binding ability in the range 45-80°C and 0-8%, respectively. Scanning electron micrographs of the ultrastructure of gels formed by myosin showed a three dimensional network of overlapping fibers in the presence of salt and phosphate and a sponge-like network in their absence. Since the ultrastructure of the gel formed by myosin heavy chains was comparable to that of myosin, it was concluded that the heavy chain core of the myosin molecule plays an important role in the heat-induced gelation of myosin. The relationship between the formation of a three dimensional network of fibers by the heavy chains of myosin and the mechanism of binding meat pieces was discussed.

    MlCROSTRUCTURE OF ISOLATED SOY PROTEIN IN COMBINATION HAM (1979)

    Notes: Combination hams were prepared by injecting excised porcine muscles with a brine containing solubilized isolated soy protein. The microstructure of the muscle in the combination ham was compared to that of a water added ham to determine the location of the isolated soy protein. The effect of massaging on the location of the isolated soy protein was also studied. The results showed that the isolated soy protein occupied primarily perimysial spaces and the massaging acts to incorporate these proteins into the endomysial spaces and mix them with extracted myofibrillar proteins. The isolated soy protein appeared to enhance myofibrillar protein extraction by binding water, thus increasing the effective concentration of salt and phosphate. Scanning electron microscopy showed that the gel formed by the isolated soy protein possessed a denser structure than the gel formed by a crude myosin preparation. The gel formed by a mixture of myosin and isolated soy protein possessed a structure more comparable to the structure of the crude myosin gel.

    GEL STRUCTURE OF NONMEAT PROTEINS AS RELATED TO THEIR ABILITY TO BIND MEAT PIECES (1979)

    Notes: Investigations on the binding abilities of some nonmeat proteins showed that those studied were inferior to the binding ability previously reported for myosin. Their binding abilities in the presence of 8% salt and 2% sodium tripolyphosphate were ranked from highest to lowest as wheat gluten, egg white, corn gluten, calcium reduced dried skim milk, bovine blood plasma, isolated soy protein and sodium caseinate. Structures of gels formed by these proteins and mixtures of them with crude myosin showed that a three dimensional network of protein fibers is not indicative of good binding ability. The types of molecular interactions stabilizing their gel structures are thought to be more important.

    SENSORY, TEXTURAL AND YIELD PROPERTIES OF A COMBINATION HAM EXTENDED WITH ISOLATED SOY PROTEIN (1979)

    Notes: Combination hams were prepared by injecting deboned ham muscles with brines containing solubilized isolated soy protein. The muscles were injected to levels of 30%, 45% or 60%, and then subjected to either 0 hr or 18 hr of intermittent massaging. The effects of massaging, isolated soy protein, and the level of injection on binding strengths, cooking yields and taste-panel scores were examined. Massaging and isolated soy protein improved both binding strength and cooking yield. increasing levels of injection decreased binding strength and cooking yield. Massaging improved uniformity, textural appeal, and overall acceptability, but decreased tenderness and did not affect juiciness and flavor.

    CRUDE MYOSIN FRACTIONS AS MEAT BINDERS (1979)

    Notes: A model system designed for the Instron Universal Testing Machine to record the peak force required to separate pieces of meat at a binding junction was used to measure the ability of various muscle protein fractions to bond meat pieces. The binding abilities of crude myosin preparations were found to be significantly greater than the binding ability of either a muscle homogenate free of fat and sarcoplasmic proteins, a total muscle homogenate or a nonprotein control consisting of salt, phosphate and water. Crude myosin fractions extracted from pre- and post-rigor bovine muscle over short and long extraction times with three extracting solutions, Guba-Straub, Hasselbach-Schneider and Weber-Edsall, were measured for binding ability, yield and mole ratio of myosin to actin by scanning SDS-PAGE gels. Results showed that the Hasselbach-Schneider myosin was superior to the Guba-Straub and Weber-Edsall myosins in both binding ability and yield. Comparisons of mole ratios with binding abilities showed that when the same extracting conditions were present the higher proportion of myosin resulted in a higher binding ability. However, when different extracting conditions were present, the higher proportion of myosin did not always give a higher binding ability. These results imply that ionic interactions are inculpated in the binding phenomenon.

    Description / Table of Contents: Zusammenfassung Durch Wiederfindungsmessungen mit Hilfe von i.p. injiziertem3H-Digoxin und125-markiertem Digoxin konnte gezeigt werden, daß Standardkonzentrationen von Digoxin, die arzneistoffreiem Gewebe zugesetzt werden, zu falsch negativen Bestimmungen führen können. Der Vergleich der Radioaktivität aus verschiedenen Geweben vor und nach Extraktion mit Amberlite XAD-2 ergab, daß nur um 50% der gesamten Glykosidmenge extrahiert wird: BD9-(Berlin)-Ratten wurden 15mg/kg Körpergewicht β-Methyldigoxin i.p. injiziert. Aus Extrakten mit Amberlite XAD-2 von Blut, Niere, Herz und Leber konnten außer β-Methyldigoxin dessen Metaboliten Digoxin und Digoxinbidigitoxose ab 60 ng/Fleck in prozentualen Anteilen als Fluoreszenzflecke sichtbar identifiziert werden, durch die Anwendung von HPTLC- Platten mit Fluoreszenzzusatz. Radioimmunologisch bestimmte Konzentrationen fanden sich in guter Übereinstimmung mit dünnschichtchromatographischen Ergebnissen.
    Notes: Summary The recovery measurements in rat tissues performed via i.p. injected radioactive digoxin derivates (3H-digoxin,125-digoxin derivative) showed that approximately 50% of the total glycoside content will be extracted. Thus, an addition of digoxin standards to drug-free tissues may lead to false negative determinations. By comparison of the radioactivity before and after extraction the following results were obtained: After i.p. application of 15 mg/kg of β-methyldigoxin to BD 9 (Berlin)-rats the resulting tissue concentrations were extracted by Amberlite XAD-2. β- Methyldigoxin and its metabolites digoxin and digoxinbisdigitoxide could be separated and distinguished from artifacts by fluorescence detection on HPTLC-plates with a detection limit of 60 ng/spot. Concentrations determined by radioimmunoassay are in satisfactory agreement with HPTLC results.
