    Notes: The extent of culture associated variation generated by a brief passage through tissue culture was evaluated in four maize inbred backgrounds: A641, H99, MS7I, and PA91. The progeny resulting from two generations of self-pollination from the original regenerates were evaluated along with appropriate sexual controls in a replicated field experiment. Eighty regenerate lines and twenty controls were evaluated in each background. Data were collected for 22 traits and were subjected to analysis of variance, discriminant analysis, and principal component analysis. In 58 of 88 combinations of background and trait, the contrast of controls vs. regenerates was significant. The culture cycle increased the variation and changed the association between traits. Testcross hybrids involving these regenerate lines and controls were also evaluated with little or no significant variation or differences between regenerate hybrids and controls being detected.

    Tissue factor and tissue factor pathway inhibitor (2004)

    Notes: The classical ‘cascade/waterfall’ hypothesis formulated to explain in vitro coagulation organised the amplification processes into the intrinsic and extrinsic pathways. Recent molecular biology and clinical data indicate that tissue factor/factor-VII interaction is the primary cellular initiator of coagulation in vivo. The process of blood coagulation is divided into an initiation phase followed by a propagation phase. The discovery of tissue factor pathway inhibitor further supports the revised theory of coagulation. Tissue factor is also a signalling receptor. Recent evidence has shown that blood-borne tissue factor has an important procoagulant function in sepsis, atherosclerosis and cancer, and other functions beyond haemostasis such as immune function and metastases.

    INFLUENCE OF pH ON THE BINDING OF COPPER, ZINC AND IRON IN SIX FIBER SOURCES (1979)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 44 (1979), S. 0

    Notes: The binding of endogenous copper, zinc and iron in six fiber sources was examined via incubation under three pH conditions: (1) pH 0.65; (2) pH 6.8; and (3) a sequential treatment of pH 0.65, neutralization, then pH 6.8. After both the pH 6.8 and sequential treatments, most of the minerals remained bound in the residues, while little remained bound after the acidic treatment. This indicated that the minerals were rebound when the pH was raised from very acidic to only slightly acidic. Titrations of the untreated fiber sources showed that protein influenced the hydrogen ion buffering capacity. After enzymatic proteolysis, the buffering capacities were reduced and other physicochemical properties appeared to gain influence.

    Notes: [Auszug] It occurred to us that if an equilibrium existed between thiolbenzoic acid and thiolacetic acid: C6H5COSH -f CH3COOH ^ C6H5COOH + CH3COSH the reaction might be persuaded to go towards completion by removal of the latter as the lowest-boiling component. We have, in fact, obtained thiolacetic acid ...

    Thrombocytopenia in the parturient (2004)

    Notes: Thrombocytopenia in pregnant women can be associated with substantial maternal and neonatal morbidity. It may result from a range of conditions and early implementation of some specific treatment may improve both maternal and neonatal outcome. In this review we discuss the clinical features of the more common causes of thrombocytopenia associated with pregnancy, and provide an overview of the anaesthetic considerations.

    The effect of silicon on the eutectic grain size of gravity cast Zn-12% Al (1986)

    Notes: Abstract For gravity castings made from Zn-12% Al alloys wide variations of impact strength have been observed that could not be explained in terms of casting soundness. Previous unpublished research isolated trace impurities of silicon as the cause of a large increase in eutectic grain size and subsequent decrease in impact strength. In the present study the effect of silicon on the as-cast eutectic grain size and impact strength of Zn-12Al is confirmed. Thermal analysis and interface equilibration experiments indicate that silicon impedes nucleation of the eutecticβ phase. Finding that the presence of silicon lowers the primaryα′/eutectic liquid interfacial energy, it is concluded that silicon, rejected by the pro-eutecticα′phase during primary solidification, poisons the interface causing the difficulty with the nucleation of eutecticβ on the primaryα′ surface leading to the increase in eutectic grain size.

    Genetic analysis of anther culture response in maize (1987)

    Notes: Summary Response frequencies in maize (Zea mays L.) anthers cultured in vitro were examined in a diallel set of crosses among four commercial inbred lines. Significant differences among the genotypes were observed, with the crosses H99xFR16 and Pa91xFR16 displaying the highest responses. General (GCA) and specific (SCA) combining ability mean squares were calculated and determined to be highly significant. GCA effects among the parental lines were highest for FR16 and lowest for LH38. Nongenotypic, plant-toplant differences were also found to make a significant contribution to the overall variation observed. The results from this study indicate that parents which give rise to highly responsive hybrids can be identified and that genetic improvement is possible through selection.

    Selection for increased anther culture response in maize (1988)

    Notes: Summary Anther culture of a three-way cross, (H99 × FR16) × Pa91, resulted in the regeneration of two anther-derived plants which were crossed to produce an F1 progeny. Fourteen S1 families derived from this cross were evaluated for their anther culturability. Dramatic increases in the level of androgenesis, expressed as the percentage of cultured anthers which produced embryo-like structures, were observed. An overall mean response frequency of 23.4% was observed for the S1 families. This was compared to a 3.5% response in the original three-way cross. These results demonstrate that genetic improvement of in vitro androgenesis in maize is possible and that anther culture per se constitutes a procedure for selecting genes which favor increased levels of response.

    Histochemical light microscopic study of catecholamine containing paraganglia in the human pelvis (1976)

    Notes: Summary Histological and histochemical techniques have been employed to determine the structure and autonomic innervation of paraganglia located in the human pelvis. In foetal and early postnatal tissues, paraganglia formed rounded cellular masses which were frequently in company with the autonomic nerves and ganglia of the urinary bladder and other pelvic viscera. The constituent cells contained only small amounts of cholinesterase and were unrelated to enzyme positive autonomic nerves; acetylcholinesterase containing nerves were occasionally observed in the capsule and the fibrous septa of the pelvic paraganglia. In early postnatal specimens, pelvic paraganglia frequently contained single or multiple “pacinian-like” corpuscles, each possessing a central region which was rich in both acetyl and pseudocholinesterase. These structures were rarely observed within autonomic ganglia and were absent 4 1/2 years post partum. By means of a histochemical technique, pelvic paraganglia were found to contain catecholamine which was attributed to the presence of relatively large quantities of noradrenaline. These observations have been discussed with particular reference to the results of other studies on the autonomic innervation of paraganglia.
