The ultrastructural morphometry of collagen fibril populations in 24 calcaneal tendons obtained from 12 Fischer 344 rats were studied to elucidate matrical changes induced by food restriction and/or endurance exercise. Rats were randomly assigned to four equal groups: ad libitum control (AC), ad libitum exercise (AE), restricted diet control (RC) and(More)
Studies were undertaken to compare the effects of exercise and food restriction on body weight (BW), muscle weight (MW), muscle fiber size, and proportion of muscle fiber types. 20 male Fischer 344 rats were randomly assigned to four equal groups: ad libitum-fed control (AC), ad libitum-fed exercise (AE), food restricted control (RC) and food restricted(More)
STUDY QUESTION Could drugs targeting ATP-sensitive K(+) (K(ATP)) channels prevent any spontaneous increase in intracellular Ca(2+) that may occur in human metaphase II (MII) oocytes under in vitro conditions? SUMMARY ANSWER Pinacidil, a K(ATP) channel opener, and glibenclamide, a K(ATP) channel blocker, prevent a spontaneous increase in intracellular(More)
