    Notes: 1. Experimental growth data for Arctic charr (Salvelinus alpinus L.), all fed on excess rations, from 11 European watercourses between 54 and 70°N were analysed and fitted to a new general growth model for fish. The model was validated by comparing its predictions with the growth rate of charr in the wild.2. Growth performance varied among populations, mainly because of variation in the maximum growth potential, whereas the thermal response curves were similar. The estimated lower and upper temperatures for growth varied between −1.7 to 5.3 and 20.8–23.2 °C, respectively, while maximum growth occurred between 14.4 and 17.2 °C.3. There was no geographical or climatic trend in growth performance among populations and therefore no indication of thermal adaptation. The growth potential of charr from different populations correlated positively with fish body length at maturity and maximum weight in the wild. Charr from populations including large piscivorous fish had higher growth rates under standardised conditions than those from populations feeding on zoobenthos or zooplankton. Therefore, the adaptive variation in growth potential was related to life-history characteristics and diet, rather than to thermal conditions.

    Effects of habitat improvement on the brown trout, Salmo trutta L., population of a northern Swedish stream (1989)

    Notes: Abstract. Effects of four types of habitat improvement structures have been evaluated in Låktabäcken Creek, a steep and infertile brown trout, Salmo trutta L., stream in Northern Sweden. Boulder dams proved to be the most efficient structure, increasing brown trout densities by up to three times and standing crop by up to five times their original values. Log deflectors gave similar effects on standing crop while boulder groupings and boulder deflectors seemed to be inefficient. Older/larger fish were primarily favoured. No increase in growth or enhanced condition has been registered. Obviously, profitable stream positions for older fish were lacking in Läktabäcken Creek. An increase in the amount of cover and an increase in the winter survival might be secondary effects of alterations.

    Pharmacokinetic study of IV infusions of adriamycin (1985)
    Springer
    European journal of clinical pharmacology 28 (1985), S. 205-212

    Notes: Summary The plasma pharmacokinetics of adriamycin has been studied in 21 cancer patients (31–85 years old) without liver tumours after short (3.00 min) and prolonged (45 min-16h) i.v. infusions. The area under the plasma concentration-time curve and the maximum plasma concentration compensated for dose variation showed a more than 3-fold individual variation. The pharmacokinetics of adriamycin was linear. There was no pharmacokinetic rational for variation of the dose with the age of the patients. There was good agreement between the measured plasma concentration-time curves for prolonged infusions and curves predicted from pharmacokinetic data from short term infusions.
