Yuki Uchida et al.
The aim of this study was to determine whether estrogen modulates central and peripheral responses to cold in female rats. In ovariectomized female rats with and without administered estrogen [E(2) (+) and E(2) (-), respectively], the count...
Overshoot phenomenon of oxygen uptake during recovery from maximal exercise in patients with previous myocardial infarction [0.03%]
心肌梗塞患者在最大负荷运动后恢复过程中的摄氧量过冲现象
Osamu Nagayama,Akira Koike,Takeya Suzuki et al.
Osamu Nagayama et al.
The overshoot in oxygen uptake (VO2 overshoot) during recovery from maximal exercise is thought to reflect an overshoot in cardiac output. We investigated whether this phenomenon is related to cardiopulmonary function during exercise in car...
Adaptive effects of the beta2-agonist clenbuterol on expression of beta2-adrenoceptor mRNA in rat fast-twitch fiber-rich muscles [0.03%]
克仑特罗对大鼠快缩纤维丰富肌群β2肾上腺素受体mRNA表达影响的适应性反应
Shogo Sato,Sachiko Nomura,Fuuun Kawano et al.
Shogo Sato et al.
Administration of the beta(2)-agonist clenbuterol has been shown to reduce the expression of beta(2)-adrenoceptor (AR) mRNA in fast-twitch fiber-rich (extensor digitorum longus, EDL) muscle without changing that in slow-twitch fiber-rich (s...
Effects of nonexhaustive bouts of high-intensity intermittent swimming training on GLUT-4 expression in rat skeletal muscle [0.03%]
高强度间歇游泳锻炼对大鼠骨骼肌GLUT-4表达的影响

Eri Fujimoto et al.
We previously reported that 14 bouts of exhaustive high-intensity intermittent training [20 s periods of swimming while carrying a weight (14% of body weight), separated by pauses of 10 s] is the highest stimuli in terms of exercise trainin...

Shu-Ting Hu et al.
intracellular Ca(2+) handling by the sarcoplasmic reticulum (SR) plays a crucial role in the pathogenesis of heart failure (HF). Despite extensive effort, the underlying causes of abnormal SR Ca(2+) handling in HF have not been clarified. T...
