    Notizen: The aim of the present investigation was to study the possible effects of specificity of training on muscle strength and anaerobic power in children from different sports and at different performance levels in relation to growth and maturation status. Hundred and eighty-four children of both gender participating either in swimming, tennis, team handball or gymnastics were recruited from the best clubs in Denmark. Within each sport, the coach had divided the children into an elite (E) and non-elite (NE) group according to performance level and talent. Tanner stage assessment and body weight and height measurements were performed by a physician. The anaerobic performances were assessed by Wingate tests and jumping performance in squat jump (SJ), countermovement jump (CMJ) and drop jump (DJ) from two heights. Most of the differences between groups in Wingate performance disappeared when the data were normalised to body mass. The gymnasts were the best jumpers and their superiority were increased in the more complex motor coordination tasks like DJ. The results may indicate some influence of training specificity, especially on the more complex motor tasks as DJ and there may be an effect of training before puberty. The performance in the less complex motor tasks like cycling and SJ and CMJ may also be influenced by specific training, but not to the same extent, and heritance may be an important factor for performance in these anaerobic tasks.

    Calcineurin Phosphatase Activity and Immunosuppression. A Review on the Role of Calcineurin Phosphatase Activity and the Immunosuppressive Effect of Cyclosporin A and Tacrolimus (2003)

    Thema: Medizin
    Notizen: The mode of immunosuppressive action of tacrolimus (FK506) and cyclosporin A has been elucidated. Both drugs bind to proteins in the cytoplasm to form complexes, which in turn inhibit the phosphatase activity of calcineurin, an important limiting step in the activation of T cells. The association between drug uptake (pharmacokinetics) and enzyme inhibition (pharmacodynamics) is under current investigation. Great variations in the correlation between blood drug levels and enzyme inhibition could indicate that monitoring calcineurin phosphatase activity for treatment might be superior to monitoring blood drug levels.

    Notizen: Summary We investigated in a randomized, prospective study the influence of improved blood glucose control during 2–3 years in young insulin-dependent diabetic (IDDM) patients with microalbuminuria, which is indicative of early nephropathy. Patients were randomized either to intensive treatment by continuous subcutaneous insulin infusion (CSII) (n =9) or CT (n =9). Kidney biopsies were taken at baseline and after 26–34 months. End points were structural changes in the glomeruli. Sensitive, quantitative, morphometric methods were used. The blood glucose control improved significantly (p =0.01) during the study in the CSII-group as glycated haemoglobin (HbA1 c) fell from 10.1 % ([95 % CI] 8.9–11.3) to 8.6 % (7.9–9.2), but not in the CT-group, 10.1 % (8.3–11.9) vs 9.7 % (8.7–10.8). Mean HbA1 c during the study period was significantly lower in the CSII-group than in the CT-group, 8.7 % (8.1–9.3) vs 9.9 % (8.5–11.3), p =0.04. Basement membrane thickness (BMT) increased in both groups, most (CT vs CSII, p =0.03) in the CT-group: 140 nm (50–230) vs CSII: 56 nm (27–86). In the CT-group only an increase was seen in matrix/mesangial volume fraction (p =0.006) and matrix star volume (p =0.04). Furthermore, a positive correlation between mean HbA1 c during the study and change from baseline in BMT (r =0.70, p =0.001) and matrix/glomerular volume fraction (r =0.33, p =0.09, NS) was demonstrated. Albumin excretion rate correlated significantly to BMT and most of the matrix parameters. The present study shows that during a period of only 2.5 years, a close relationship between the level of mean blood glucose and progression of glomerular morphological changes in early diabetic nephropathy can be demonstrated.

    Notizen: Summary We have investigated the effect of long-term strict glycaemic control on peripheral and autonomic nerve function in 45 IDDM patients (age 18–42 years, diabetes duration 7–23 years) without clinical signs of neuropathy or other neurological disease. They were randomly assigned to treatment either with continuous insulin infusion, multiple injections (4–6 times daily), or conventional treatment (twice daily) for 4 years and followed prospectively for 8 years. Motor and sensory nerve conduction velocities were measured at the start and after 8 years. Autonomic nerve function tests were performed only once, after 8 years. A significant reduction of nerve conduction velocity was observed during 8 years in patients with mean HbA1 more than 10% (n=12, group mean 10.9%, range 10.1–13.2%) compared to patients with HbA1 less than 10% (n=33, group mean 9.0%, range 7.5–9.9%). Change of motor nerve conduction velocity in the peroneal nerve was: −4.8±4.9 (SD) vs −2.2±5.3 m/s (p〈0.01). Change of motor nerve conduction velocity in the posterior tibial nerve was: −6.8±5.7 vs −3.9±5.1 m/s (p〈0.05). No significant changes were observed in the ulnar nerve. Change of sensoric nerve conduction velocity in the sural nerve was: −8.9±8.0 vs −4.6±5.3 m/s (p〈0.05). Multiple regression analysis showed that a change in HbA1 of 1% resulted in a 1.3 m/s change in nerve conduction velocity during 8 years. A significantly lowered heart-rate variation during deep breathing (p〈0.05) and heart-rate response to standing (p〈0.01) was found in patients with HbA1 more than 10% compared to patients with HbA1 less than 10%. This study confirms that the long-term lowering of blood glucose retards the deterioration in nerve conduction velocity observed in the diabetic nerve.

    Glomerular charge selectivity and the influence of improved blood glucose control in Type 1 (insulin-dependent) diabetic patients with microalbuminuria (1992)

    Schlagwort(e): Type 1 (insulin-dependent) diabetes mellitus ; nephropathy ; microalbuminuria ; continuous subcutaneous insulin infusion ; metabolic control ; glomerular charge selectivity

    Thema: Medizin
    Notizen: Summary We first compared glomerular charge selectivity index in two matched groups of Type 1 (insulin-dependent) diabetic patients with micro and normoalbuminuria respectively, and secondly, investigated prospectively in a randomized clinical trial, the influence of improved metabolic control on selectivity index in diabetic patients with microalbuminuria. In Study 1, 27 patients with microalbuminuria (albumin excretion 〉-15 μg/min in at least two out of three overnight urine samples) were matched (age, diabetes duration, mean 1-year HbA1c, gender) with normoalbuminuria patients (n=24), and in Study 2, 23 microalbuminuric patients were randomly allocated to either intensive (continuous subcutaneous insulin infusion) or conventional treatment. Glomerular charge selectivity index was measured as IgG/IgG4 selectivity index, i.e. total IgG/IgG4 clearance ratio in timed overnight urine samples. The microalbuminuric patients had a significantly reduced selectivity index compared to the normoalbuminuric patients: 1.20 (0.92–1.40) vs 1.68 (1.22–2.21), median and 95% confidence interval (p〈0.01). In Study 2, the HbA1c improved in the intensive-treatment group compared to the conventional-treatment group: at 2, 6 and 12 months the difference in mean percentage HbA1c between the groups was 1.1, 1.2 and 1.4, respectively (p〈0.01). A sharp 50% increment in IgG/IgG4 selectivity index was seen in the intensive-treatment group during the first 6 months (p〈0.05 compared to the conventional group). We conclude that adolescents and young adults in an early stage of diabetic nephropathy have reduced glomerular charge selectivity, which may be improved by reducing the mean blood glucose level.

    Transient heating of opaque and semitransparent materials by radiation during processing (2000)

    Notizen: Abstract Analysis is presented of transient heating of opaque and semitransparent (translucent) materials by external radiation sources. Such problems arise in materials processing and manufacturing applications. Dynamic temperature distributions are calculated in a plate (slab) of material by accounting for spectral nature of the radiation source and the radiative properties of the material. Effects of radiation properties influenced by the choice of material to be heated, chemical and mechanical treatment, radiation source temperature, and convective heat transfer are considered. Differences in temperature response of opaque and semitransparent materials are examined. It is shown that the temperature distribution in a semitransparent material heated by an external radiation source is more uniform than in an opaque material for otherwise the same conditions owing to the “long range” transport of radiation. Treatment of a semitransparent material as opaque results in an unrealistic prediction of temperature distribution when the material is heated by an infrared radiation source.
