    Cellular cholesterol regulation — A defect in the Type 2 (non-insulin-dependent) diabetic patient in poor metabolic control (1990)
    Springer
    Diabetologia 33 (1990), S. 93-99 
    Details
    ISSN: 1432-0428
    Keywords: Type 2 (non-insulin-dependent) diabetes mellitus ; LDL ; cholesterol ; esterification ; glycosylation

    Notes: Summary This study investigates the relationship between Type 2 (non-insulin-dependent) diabetes mellitus and hypercholesterolaemia with regard to delivery of cholesterol to cells and regulation of endogenous cholesterol synthesis. The ability of LDL, from hypercholesterolaemic and Type 2 diabetic patients, to suppress cellular cholesterologenesis and to enhance mitogen-stimulated lymphocyte proliferation was compared. Cholesterol synthesis was estimated by measuring [14C]-acetate incorporation into cholesterol and lymphocyte proliferation was assessed by [3H]-thymidine incorporation into mitogen-stimulated normal lymphocytes. The results indicate that LDL from both Type 2 diabetic patients in poor metabolic control and hypercholesterolaemic patients was significantly less effective (p 〈 0.001) than LDL from non-diabetic normocholesterolaemic subjects in suppressing cholesterol synthesis in lymphocytes. LDL from all hypercholesterolaemic patients enhanced lymphocyte proliferation to a greater extent than LDL from normocholesterolaemic subjects and this effect was significantly increased using LDL from Type 2 diabetic, hypercholesterolaemic patients. Both suppression of [14C]-acetate incorporation and enhancement of [3H]-thymidine uptake could be related to an increased esterified/free cholesterol ratio in the LDL particle. The fact that cholesterol synthesis and cell proliferation were markedly altered by the above changes in LDL composition suggests a mechanism for cellular cholesterol accumulation in the Type 2 diabetic patient, even in the absence of elevated serum cholesterol levels.

    Alterations in apolipoprotein B-48 in the postprandial state in NIDDM (1994)

    Notes: Summary The intestine is a major site of cholesterol synthesis and produces apolipoprotein B-48, which is critical for intestinal cholesterol absorption and secretion. The purpose of this study was to examine postprandial changes in apolipoprotein B-48 in diabetes. Six non-insulin-dependent diabetic patients and six non-diabetic control subjects were given a high-fat meal (1300 kcal) and blood samples were taken pre- and postprandially, from which the triglyceride-rich lipoprotein fraction was isolated by ultracentrifugation (density 〈 1.006 g/ml). Apolipoprotein B-48 was separated on 4–15 % gradient gels and quantified as a percentage of the fasting concentration by densitometric scanning. Total protein, triglyceride and cholesterol in the triglyceride-rich lipoprotein fraction, blood glucose, and serum insulin were also measured. Diabetic patients exhibited a postprandial triglyceride-rich apolipoprotein B-48 profile significantly different from that of control subjects (p 〈 0.05). The triglyceride and total protein concentration in the triglyceride-rich lipoprotein fraction mirrored the post-prandial profile and apolipoprotein B-48 in both groups. Significantly different patterns for triglyceride (p 〈 0.02) and total protein (p 〈 0.05) following the fat-rich meal were observed in the two groups. Fasting and postprandial triglyceride-rich lipoprotein cholesterol and total apolipoprotein B were significantly higher in diabetic patients than in control subjects (p 〈 0.05). Since apolipoprotein B-48 is the structural protein of intestinally-derived lipoprotein particles, these studies suggest an abnormality in intestinal lipoprotein metabolism in diabetes.

    A case of juvenile lipidosis: Electron microscopic, histochemical and biochemical studies (1968)

    Description / Table of Contents: Zusammenfassung Elektronenmikroskopische, histochemische und biochemische Untersuchungen eines Falles von juveniler Lipidose werden mitgeteilt. Die neuronalen Einschlüsse sind zumeist von einer unit membrane umgeben und zeigen fingerabdruckähnliche Muster. Membranovesiculäre Körperchen finden sich ebenfalls in den Nervenzellperikaryen; typische granuläre Lipofuscinkörperchen werden aber nicht gesehen. Die Astrocyten der Rinde enthalten eine ähnliche Art von Einschlüssen, von denen aber die Einschlüsse in den Astrocyten der Marksubstanz völlig verschieden sind. Die Lokalisation der Aktivität von saurer Phosphatase in allen Einschlußtypen läßt an ihre mögliche lysosomale Natur denken. Die biochemische Analyse deckt keine spezifischen Abweichungen auf.
    Notes: Summary Electron microscopic, histochemical and biochemical studies of a case of juvenile lipidosis have been presented. The neuronal inclusions were mostly unit membranebound with fingerprint-like patterns. Membrano-vesicular bodies were also found in the neuronal perikarya, but “typical” granular lipofuscin bodies were not seen. Cortical astrocytes contained a similar type of inclusion but the inclusions in the astrocytes in the white matter were quite different. The localization of acid phosphatase activity in all types of inclusions suggests their possible lysosomal nature. Biochemical analysis failed to pin-point any specific abnormalities.

    Description / Table of Contents: Zusammenfassung In fünf Fällen von Dystrophia myotonica zeigte die elektronenoptische Untersuchung von bioptisch entnommenem Material zentrale und subsarkolemmale Kerne, die komplexe vacuoläre Areale um myofibrilläres Material enthalten. Diese bisher nicht beobachtete Veränderung könnte durch Verlagerung von myofibrillärem Material in den Kern während seiner Wanderung in das Faserzentrum durch Invagination, aber nicht Durchbrechung der Kernmembran bedingt sein.
    Notes: Summary In five cases of dystrophia myotonica electron microscope preparations of muscle taken at biopsy showed both centrally placed and subsarcolemmal nuclei containing complex vacuolar areas enclosing myofibrillar material. It is suggested that this appearence, which has not been seen in any other condition, may be due to the forcing of myofibrillar material into the nucleus during its migration to the centre of the fibre invaginating but not breaching its membrane.

    Notes: The dissociation constants for an acetonitrile-zinc complex, (CH3CN)Zn2+, were measured in aqueous solutions containing zinc salts (40-80%, w/w) and acetonitrile by Raman spectroscopy. Quantitative measurements of the intensity of the free and complexed ν(CN) Raman bands at 2264 and 2320 cm-1, respectively, were used to determine the average enthalpy and entropy of the complex dissociation to free acetonitrile in the temperature range 293-343 K for a 70% (w/w) solution of zinc chloride (0.052 mol) in an aqueous solution containing acetonitrile (0.024 mol); δH° and δS° values of 8.4 ± 0.5 kJ mol-1, respectively, were determined.

    Notes: The application of Raman spectroscopy to polymers and polymerization processes is surveyed and the advent of recent advances in instrumental techniques to polymer analysis is highlighted. Some of the problems of the more widely-used infrared spectroscopic methods, for example in microstructural analysis of polydienes and copolymers, are discussed and the advantages of the Raman spectroscopic technique are explained. The use of near-infrared excitation and Fourier-transform Raman instrumentation for process monitoring and polymer composite studies is discussed. Raman microscopic and waveguide spectroscopic studies of small samples and polymer coatings on substrates are considered. Other applications are mentioned in the areas of polymer orientation, surface-enhanced Raman scattering, conducting polymers, biopolymers and time-resolved studies.
