    Notes: [Auszug] The determination of size of the nucleus and nucleolus in different stages of growth of the oocyte is important in such a study. Very little work on volume relationships of the different cell structures during growth has been done, and, so far as I am aware, no information is available regarding ...

    Notes: Summary Effects of phenformin on blood sugar, serum triglyceride, thrombin time, euglobulin clot lysis time and cardiovascular complications were studied in maturity onset diabetics and in atherosclerotic patients with or without diabetes, for a period of 14–18 months. Phenformin has shown the characteristic properties of an antifibrinopathic agent in that it prolongs thrombin time and enhances fibrinolysis. The hypoglycaemic effect of phenformin was found to be directly related to its antifibrinopathic action. Plasma lipids fell in all cases. Absence of fresh cardiovascular complications and improvement in anginal symptoms were observed. The metabolic, haematological and clinical benefits of phenformin and its limitations in maturity onset diabetes and atherosclerosis may be explained by the effects of the drug upon the thrombin-fibrinogen reaction. These results lend support to the hypothesis of a primary fibrinopathic pathogenesis in maturity onset diabetes mellitus and atherosclerosis.

    Notes: Abstract The transcriptional status of the negatively heteropycnotic spermatogonial X chromosome of Acheta was analysed on the basis of both its replication pattern and its response to 3H-UdR induced aberrations. On the basis of the latter criterion the negatively heteropycnotic spermatogonial X chromosome of Acheta has been judged to be transcriptionally inactive. This contrasts with the situation observed in somatic cells. It also contrasts with the behaviour of the X chromosome in spermatogonia of other Orthopterans.

    Notes: Abstract The functional status of the X chromosome in Acheta domesticus has been analysed at the whole chromosome level on the basis of (1) 3H-thymidine autoradiography, (2) 5-BrdU/AO fluorescence microscopy, (3) in vivo 5-BrdU incorporation and (4) 3H-UdR induced aberrations. The rationale of these techniques in relation to the functional aspect of the X chromosome is that the inactive X chromosome would (1) show asynchrony in DNA synthesis, (2) show differential fluorescence, (3) respond differentially to in vivo 5-BrdU treatment and (4) the active X chromosome would show aberrations when treated with 3H-Uridine. From the results, it appears that the X chromosomes in both male (XO) and female (XX) somatic cells of Acheta are euchromatic (active). Further, the single X in the male is transcriptionally as active as the two X chromosomes in the female. In other words, the single X in the male is hyperactive when compared with the single X in the female. From this it is inferred that the male X chromosome is differentially regulated in order to bring about an equalization of it's gene product(S) to that produced by both Xs in the female. Drosophila melanogaster has a comparable system of dosage compensation. Thus, Acheta is yet another insect showing evidence for an X chromosome regulatory mechanism of dosage compensation. Additionally, it is surmised that sex determination in Acheta is based on an autosomes/X chromosome balance mechanism.
