    Life Events, Social Support and the Risk of Sudden Infant Death Syndrome (1996)

    Notizen: The effects of a lack of maternal social support and stressful life events on the risk of Sudden Infant Death Syndrome (SIDS) were examined by case-control design: 390 cases and 1592 control infants. A seven item index of mother's social support was used. A possible 21 life events experienced by each family were summed and then put into one of three categories: 0-2, 3-5, and 6 or more life events. Similar levels of maternal social support were found for both groups. SIDS families experienced significantly more stressful life events than control families, but once social factors had been taken into account this association was lost.

    Notizen: [Auszug] WHEN our letter to NATURE of January 27 was written, we were under the impression that we were the only workers in this field, as the researches of Wiedemann, Eberts, and de Hemptinne in 1897 and earlier years had led to no results in the particular region which we were investigating. Prof. ...

    Notizen: [Auszug] IN conjunction with Mr. W. H. McVicker, we have begun an investigation of the spectra emitted by the vapours of compounds when subjected to waves from a Tesla transformer passing between two glass-coated electrodes. For the sake of clarity, these spectra may be termed electro-luminescence ...

    Notizen: [Auszug] WHILE engaged in a research on the polymerisation of unsaturated compounds, we were led to try the action of a strongly heated platinum wire on various organic substances. It is unnecessary at this stage to discuss our general results, and we will therefore deal at once with the action of the ...

    Muscle fluorometry: A determination of the depth of penetration (1985)
    Springer
    Cellular and molecular life sciences 41 (1985), S. 456-458

    Notizen: Summary Fluorometric recordings of NADH (nicotinamide adenine dinucleotide) were made on rabbit papillary muscles. The specimens were placed between the UV light source and a small window of the detection stage. As the muscle was moved over the window in a transverse direction, simultaneous measurement could be taken of transmitted UV light and fluorescent light for various thicknesses of tissue. It is concluded that a muscle thinckness of 0.65 mm, is optimal before absorption of the incident light decreases the fluorescence signal.

    Postprandial changes in serum concentrations of individual bile salts in normal subjects and patients with acute viral hepatitis (1978)
    Springer
    Digestive diseases and sciences 23 (1978), S. 599-608 
    Details
    ISSN: 1573-2568
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Abstract A sensitive gas-liquid chromatographic assay has been used to analyze serum concentrations of the four major bile acids in both sulfated and nonsulfated forms. Twelve control subjects have been compared with 40 patients with acute viral hepatitis whose symptoms had been present from 6 to 34 days. In all subjects blood samples were collected fasting and 2 hr after a standard meal. In addition half-hourly samples were assayed for 3 hr after the meal in 6 controls and 5 patients with acute viral hepatitis. In both the control and hepatitis groups, serum concentrations of nonsulfated bile acids, especially cholic and chenodeoxycholic acids, increased after the meal. The peak levls usually occurred between 60 and 120 min in the half-hourly studies. In contrast, sulfated bile acids fell in both groups with minimum levels 60–120 min after the meal. Serum total bilirubin, aspartate aminotransferase, and alkaline phosphatase concentrations in hepatitis patients correlated significantly with postprandialitotal bile acid concentrations but were more frequently abnormal than serum total or individual bile acids. Unconjugated bile acids were not detected in control subjects but were found in 17 of the 40 hepatitis patients. Significantly higher levels of sulfated bile acids and chenodeoxycholic acid were present in hepatitis patients compared to controls. In this group of patients with acute viral hepatitis, studied soon after presentation to hospital but in some cases, some time after the onset of their disease, measurement of serum bile salts was not helpful as an index of hepatocellular function. Postprandial variation in the time of peak concentrations of the individual bile acids resulted in the postprandial bile acid studies being no more useful than fasting assays in distinguishing patients with acute viral hepatitis from control subjects.
