    Differential sensitivity of bacterial 5-enolpyruvylshikimate-3-phosphate synthases to the herbicide glyphosate (1985)

    Notes: Abstract The potent inhibition of the shikimate pathway enzyme 5-enolpyruvylshikimate-3-phosphate (EPSP) synthase by the broad-spectrum herbicide glyphosate (N-[phosphonomethyl]glycine) was confirmed for the enzymes extracted from various bacteria, a green alga and higher plants. However, 5 out of 6 species belonging to the genus Pseudomonas were found to have EPSP synthases with a 50- to 100-fold decreased sensitivity to the inhibitor. Correspondingly, growth of these 5 species was not inhibited by 5 mM glyphosate, and the organisms did not excrete shikimate-3-phosphate in the presence of the herbicide.

    Eine reversible Ermüdungserscheinung der Sekundär-Emission an Glimmkathoden mit halbleitenden Schichtenkomponenten (1954)

    Notes: Zusammenfassung Es wird gezeigt, daß bei Verwendung von Glimmkathoden mit halbleitenden Zwischenschichten der selbständige Entladungsstrom mit der Zeit abnimmt. Die Stromdichten dürfen dabei je nach der Kathodenstruktur bestimmte Erfahrungswerte nicht überschreiten. Die Abnahme des Entladungsstromes ist keine bleibende, sondern nach Löschung der Entladung und Abwarten rückgängig zu machen. Sie wird einer „reversiblen“ Ermüdung der Emissionszentren für Sekundärelektronen zugeschrieben. Die Ursache dafür wird im Halbleitergeschehen der bei den Glimmkathoden verwendeten Zwischenschichten gesehen. Die Aufhebung der Ermüdung kann durch bloßes Warten erfolgen und durch Bestrahlung der Kathode mit Ultrarot zeitlich beschleunigt werden.

    Osteocalcin und Knochenhistologie bei Osteoporose (1987)

    Notes: Summary The decoupling of bone formation and bone resorption causes an insidious bone loss that is responsible for the negative skeletal balance in the frequent form of low turnover osteoporosis. The reduction of bone formation can hardly be verified by clinical methods. Osteocalcin, a non-collagenous bone protein, has proved to be a useful new indicator of bone formation. To establish its predictable value, plasma levels of osteocalcin were compared to conventional serological data of bone turnover and to histomorphometric parameters of iliac crest trabecular bone. In cases of osteoporosis with normal bone turnover activity (as confirmed by histomorphometry) no differences were observed in any of our laboratory data including osteocalcin. However, there was a significant lower mean serum level of osteocalcin in a group of patients with histomorphometrically proven low turnover osteoporosis in comparison to those with normal bone turnover. Serum levels of osteocalcin below 2.0 ng/ml seem to indicate a low turnover in the individual case of osteoporosis while this is unlikely when serum levels above 6.0 ng/ml are measured (according to our RIA).

    Phentolamine, a deceptive tool to investigate sympathetic nervous control of insulin release (1988)
    Springer

    Keywords: Sympathetic nervous system ; α-Adrenoceptor blockers ; Phentolamine ; Insulin secretion

    Topics: Medicine
    Notes: Summary We investigated the effects of phentolamine and another more selective α2-adrenoceptor antagonist, rauwolscine, on insulin release in vivo (in female Wistar-rats) and in vitro (in perfused rat pancreas and in isolated perifused mouse islets). Phentolamine was found to significantly increase glucose-induced insulin release. On the other hand, rauwolscine failed to do so, when applied in a concentration that effectively antagonized the inhibitory effect of clonidine. These results demonstrate that phentolamine is capable of directly stimulating insulin release. This effect is thus not mediated by α-adrenoceptors. For this reason phentolamine is not an appropriate tool to study possible inhibitory effects of the sympathetic nervous system on insulin release. An enhanced insulin response as may be observed in animals and in man in the presence of phentolamine does not furnish evidence for a tonic inhibitory control of the islet cells by the sympathetic nervous system.

    Immunocytochemical identification of osteogenic bone tumors by osteonectin antibodies (1989)

    Topics: Medicine
    Notes: Summary 18 bone-forming tumours and tumour-like lesions were investigated immunocytochemically for the presence of osteonectin. A group of non-bone-forming skeletal tumours (five cartilage-forming tumours, four Ewing sarcomas and five extraskeletal sarcomas) served as controls. The studies showed that osteonectin antibodies react reliably with benign and malignant bone-forming tumours (two cases of fibrous dysplasia, three osteoid osteomas, 13 osteosarcomas). This finding was supported by protein blot studies. Osteonectin is formed by cells which do not yet possess the morphological phenotype of osteoblasts and may be regarded as a “differentiation marker” of the osteoblastic lineage. Only chondroid bone (tissue in which chondrocytes were surrounded by osteoid matrix containing type I and type II collagen) showed a positive reaction. All other primary skeletal tumours and extraskeletal soft tissue tumours were completely negative.

    Dual action of clonidine on insulin release: suppression, but stimulation when α2-adrenoceptors are blocked (1989)

    Notes: Summary As shown previously clonidine reduces glucose-stimulated insulin release and this effect is mediated by inhibitory postsynaptic α2-adrenoceptors. The present experiments demonstrate that clonidine has the additional property to also stimulate insulin release. This became evident when the a2-adrenoceptors of isolated islets were blocked by benextramine, and thus protected from being stimulated by clonidine. In the presence of benextramine, clonidine no longer reduced, but on the contrary enhanced, the release of insulin in response to glucose. In control experiments benextramine by itself failed to affect insulin release from isolated islets. These results show that the imidazoline derivative clonidine shares the property of other imidazoline compounds to enhance the insulin response to glucose. All of these agents may stimulate insulin by binding to “imidazoline-preferring” sites, that clearly differ from α-adrenoceptors.
