    Notes: Abstract Changes in glycerol production and two parameters related to energy metabolism i. e. the heat production rate and the ATP pool, were assayed during growth of Saccharomyces cerevisiae and Debaryomyces hansenii in 4 mM and 1.35 M NaCl media. For both of the yeasts, the specific ATP pool changed during the growth cycle and reached maximum values around 10 nmol per mg dry weight in both types of media. The levels of glycerol were markedly enhanced by high salinity. In the presence of 1.35 M NaCl, D. hansenii retained most of its glycerol produced intracellularly, while S. cerevisiae extruded most of the glycerol to the environment. The intracellular glycerol level of S. cerevisiae equalled or exceeded that of D. hansenii, however, with values never lower than 3 μmol per mg dry weight at all phases of growth. When D. hansenii was grown at this high salinity the intracellular level of glycerol was found to correlate with the specific heat production rate. No such correlation was found for S. cerevisiae. We concluded that during salt stress, D. hansenii possesses the capacity to regulate the metabolism of glycerol to optimize growth, while S. cerevisiae may not be able to regulate when exposed to different demands on the glycerol metabolism.

    Notes: Summary Isokinetic and static maximum plantar flexion torques were measured in 135 adults with sedentary professions. Close associations between isokinetic and static peak torques were found. Between the ages 20–49 years strength did not differ. Thereafter strength declined as a function of age. Maximum strength was 35% lower in females than in males. The right plantar flexion strength was slightly lower than the left. Maximum plantar flexion strength was about 15% lower with flexed than with extended knees. A negative exponential model characterized the decline of strength as a function of increased isokinetic velocity of angular motion. Seventy per cent or more of the variations in maximum static and isokinetic strength could be explained by anthropometric variables and by age, and by the extent of physical activity in subjects younger than 50 years. Formulas for estimation of expected static and isokinetic strengths are given.
