    IMMUNOCHEMICAL DETECTION OF TYROSINASE IN SERUM OF PATIENTS WITH METASTATIC MALIGNANT MELANOMAS AND FROM HARDY-PASSEY MOUSE MELANOMAS (1976)

    Notizen: Partially purified extracts of soluble Hardy-Passey mouse melanoma tyrosinase yielded three precipitin lines upon immunoelectrophoresis. Two immunochemically homologous but electrophoretically heterologous precipitin lines possessed tyrosinase activity whereas a more anodic line was observed which did not display tyrosinase activity.Tyrosinase from serum of patients with metastatic malignant melanomas cross-reacted with antiserum to mouse melanoma tyrosinase, and one precipitin line was seen. Immunoelectrophoresis of mixed suspensions of human serum and mouse melanoma tyrosinase yielded two tyrosinase-antibody complexes which intersected in a manner suggesting that the human and mouse melanoma tyrosinases possessed certain related antigenic groups.

    Determinants of maximal instantaneous muscle power in women aged 50–75 years (1998)

    Thema: Medizin
    Notizen: Abstract The present study aimed at analysing the age-related decline in maximal muscle power (W˙) in 52 sedentary healthy women aged between 50 and 75 years to determine whether force or velocity is the major determinant. Maximal muscle power was estimated from two types of vertical jumps, squatting (SJ) and counter‐movement (CmJ), performed on a force platform. It was obtained by measuring the vertical force (F opt) applied to the body centre of gravity and calculating the corresponding vertical velocity ( opt). An age-related decline in absolute W˙ was statistically significant in all the conditions examined and in both peak W˙ and average power ( ) values. The decrease in opt was also statistically significant. Also Fopt declined but this reduction was not statistically significant with the exception of the average value in CmJ. Not surprisingly the highest W˙ were obtained in CmJ, and the difference in power production between the two types of jump showed an age-related decrement only in . The main finding of the study was the demonstration that opt was the critical determinant of the age-related decline in W˙ in healthy elderly women.

    Effects of a low-intensity conditioning programme on V˙O2max and maximal instantaneous peak power in elderly women (1999)
    Springer
    European journal of applied physiology 80 (1999), S. 227-232

    Thema: Medizin
    Notizen: Abstract The effects of 12 weeks of a low-intensity general conditioning programme on maximal instantaneous peak power (W˙ peak) and maximal oxygen uptake (V˙O2max) were examined in 20 elderly women. After medical, familiarisation, and ethical procedures, the subjects were randomly divided into either a training and or a control group. The training group [n = 11; mean (SD) age 63.0 (3.1) years] agreed to take part in a 12-week training programme at an exercise intensity kept under 60% of the heart rate reserve for about 60 min, 3 times a week. The control group [n = 9; mean (SD) age 63.5 (3.3) years] did not perform any particular physical training. Before and after the training period, all participants underwent anthropometric measures and a maximal cycling test to exhaustion to measure their V˙O2max. In addition, W˙ peak was determined 1 week later by the subjects performing a vertical jump from a squatting position on a force platform. Following training, neither the anthropometric characteristics nor the V˙O2max changed in either of the groups. In contrast, W˙ peak increased significantly (P 〈 0.001) in the training group, but did not change in the control group. This result could be interpreted as the result of an improved level of neuromuscular activation. Furthermore, it shows that although muscle power declines with age at a faster rate than does aerobic power, its sensitivity to training seems to be higher than that of the aerobic system.

    Functionalization of an amorphous ethylene-propylene copolymer by free radical initiated grafting of unsaturated molecules (1984)
    New York : Wiley-Blackwell
    Journal of Polymer Science: Polymer Chemistry Edition 22 (1984), S. 1335-1347 
    Details
    ISSN: 0360-6376
    Schlagwort(e): Physics ; Polymer and Materials Science
    Quelle: Wiley InterScience Backfile Collection 1832-2000
    Thema: Chemie und Pharmazie
    Notizen: Functionalization of an amorphous ethylene-propylene copolymer, EPM, has been performed by means of homogeneous grafting reactions of unsaturated molecules such as dibutylmaleate, diethylfumarate, itaconic anhydride, and maleic anhydride, initiated by free radicals. Dicumylperoxide and dibenzoylperoxide have been used as a free radical source and their efficiency has been compared. A different reactivity of the unsaturated molecules has been evidenced. The influence of the nature of the solvent on the functionalization degree has been investigated, revealing a noticeable effect of the solvent either on the amounts of grafted molecules or on the secondary reactions which lead to partial degradation of the functionalized EPM chains.
