Turnover of proteins in the extreme thermophileThermus flavus

Thermus flavus contained a limited fraction of short-lived protein when growing in a complex medium; the residual proteins were stable. When incubated in buffer, the residual protein fraction was also degraded. The extent of the short-lived protein fractions was increased by increasing the temperature.     

Circadian rhythms of physiological functions in men and women as related to shift work

Operators of both sexes employed in the pulp industry were examined during a triple-shift cycle of shift work. Changes in the body temperature, heart rate, blood pressure, and sensorimotor coordination parameters were used as indicators of the circadian rhythms of their physiological functions. Sex-related differences were found with respect to a number of parameters (the muscular strength, critical flicker frequency, duration of the performance of a coordination test and coordination index, blood pressure and autonomic index, and physical general condition and mood scores). Fatigue in this type of operator activity was efficiently detected by the general condition, activity, mood (WAM) test score (especially in women), the number of errors in the test for sensorimotor coordination, and the coordination index.
