    Hyperaminoacidaemia reduces insulin-mediated glucose disposal in healthy man (1985)
    Springer
    Diabetologia 28 (1985), S. 870-872

    ISSN: 1432-0428
    Keywords: Hyperaminoacidaemia ; euglycaemic hyperinsulinaemic clamp ; glucose disposal

    Notes: Summary To determine whether hyperaminoacidaemia may modify insulin-mediated glucose disposal, normal subjects were studied with the euglycaemic glucose-clamp technique, with or without an amino acid infusion, at a rate sufficient to duplicate the plasma concentration of most amino acids. Steady-state glucose infusion rates to maintain euglycaemia were 36% lower during hyperaminoacidaemia (7.3±1.0 versus 11.4±0.8mg· kg−1· min−1, p〈0.01) at comparable insulin concentrations (92±6 versus 93±7 mU/l respectively). Thus, under conditions of hyperinsulinaemia, amino acids could compete with glucose as metabolic fuels.

    Ketone bodies increase glomerular filtration rate in normal man and in patients with Type 1 (insulin-dependent) diabetes mellitus (1987)

    Notes: Summary The purpose of this study was to investigate whether the administration of acetoacetic and hydrochloric acids in a group of control and Type 1 (insulin-dependent) diabetic patients influenced renal haemodynamics. Renal plasma flow increased from 657±88 to 762±81 ml·min−1. 1.73 m−2 in diabetic patients (p〈0.01) and from 590±71 to 691±135 in control subjects (p〈0.01). Glomerular filtration rate increased from 135±9 to 180±8 ml·min−1·1.73 m−2 in diabetic patients (p〈 0.001) and from 117±8 to 145±7 in control subjects (p〈0.01). Similar effects on renal haemodynamics, even if less pronounced, were observed with low dose acetoacetic but not with hydrochloric acid infusion. Total protein, β2-microglobulin but not albumin excretion rates were increased by acetoacetic acid. We conclude that an acute increase in blood concentration of ketone bodies within the range found in diabetic patients with poor metabolic control (1) increases renal plasma flow and glomerular filtration rate both in control subjects and diabetic patients and (2) causes a tubular proteinuria.

    Parent ion spectroscopy in the identification of advanced glycation products (1989)
    Chichester : Wiley-Blackwell
    Biological Mass Spectrometry 18 (1989), S. 713-718 
    Details
    ISSN: 0887-6134
    Keywords: Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: Advanced glycation products have been investigated by parent ion spectroscopy, employing B2/E = constant linked scans of furoyl ions obtained from hydrolysed glycated albumin and polylysine mixtures, without any extraction procedures. Using such an instrumental approach, together with exact mass measurements and collision spectroscopy, the identification of 2-(2-furoyl)-4-hydroxyl-1H-imidazole and 2-(2-furoyl)-4-carboxy-1H-imidazole among the advanced glycation products has been achieved.
