    Notes: Abstract Excited states of 108 Te were populated in the 54 Fe + 58 Ni (270 MeV) reaction using the NORDBALL detector array equipped with charged-particle and neutron detector systems for reaction channel separation. Gamma rays belonging to the neutron deficient nucleus 108 Te were identified for the first time. On the basis of γγ-coincidence and angular correlation relations a level scheme was constructed with tentative spin and parity assignments. The structure of the nucleus is discussed in the framework of systematics of heavier Te nuclei.

    Cellular cholesterol regulation — A defect in the Type 2 (non-insulin-dependent) diabetic patient in poor metabolic control (1990)

    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.

    Notes: Abstract Neutron deficient nuclei close to 100Snhave been investigated in-beam by γ-ray spectroscopic methods using the NORDBALL detector array. A beam of 270 MeV 58Niwas used to bombard a target of 54Fe.Reaction channel separation was achieved with a 4π charged particle multidetector setup together with a 1π neutron detector wall placed in the forward direction. Excited states of 102Inwere identified for the first time. The level scheme constructed from γ-γ-particle-coincidence and γ-γ-angular correlation analysis is presented. The structure of 102 In is discussed and compared to neighboring nuclei in the framework of the nuclear shell-model.

    Notes: With a Mach-Zehnder interferometer, salt concentration profiles were measured in a reverse osmosis system under natural convection with the membrane in a vertical position. The measured concentration profiles compared favorably with those predicted theoretically as long as the motion remained laminar. At large distances from the leading edge, however, the flow developed a wavy pattern, especially for bulk salt concentrations in excess of 0.1 moles/liter. As expected, whenever this motion became especially pronounced, the concentration of salt at the membrane surface was less and the production rate of fresh water greater than that predicted using the laminar analysis.

    Notes: Analytical expressions are obtained for the calculation of the time required for batch rectification of binary feeds which may be treated by assuming constant relative volatility and no column holdup. The equations cover constant reflux operations and varying reflux constant product operations for the two cases involving either a large or a small number of theoretical stages. The latter type of calculation has hitherto been possible only by tedious graphical methods. This paper introduces novel pseudoequilibrium curves which lead to simple equations of considerable accuracy. The equations obtained may be rearranged or modified so that other factors such as sharpness of fractionation may be represented analytically.
