Activity patterns of the diaphragm during voluntary movements in awake cats [0.03%]
清醒猫在自愿运动中的膈肌活动模式
Minako Uga,Masatoshi Niwa,Naoyuki Ochiai et al.
Minako Uga et al.
The diaphragm is an important inspiratory muscle, and is also known to participate in the postural function. However, the activity of the diaphragm during voluntary movements has not been fully investigated in awake animals. In order to inv...
Exertional dyspnea-related acidotic and sympathetic responses in patients with sequelae of pulmonary tuberculosis [0.03%]
肺结核后遗症患者的运动性呼吸困难相关的酸中毒和交感神经反应
Keisuke Miki,Ryoji Maekura,Toru Hiraga et al.
Keisuke Miki et al.
The objective of this study was to investigate whether exertional dyspnea correlates with exercise responses, especially arterial blood pH and plasma norepinephrine (NE) changes, in patients with sequelae of tuberculosis (TBsq). Cardiopulmo...
Sympatho-inhibitory response of the heart as a result of short-term acupuncture-like stimulation of the rat hindlimb is not augmented when sympathetic tone is high as a result of hypercapnia [0.03%]
短期类似针刺刺激引起的足三里穴对心脏的交感抑制反应不受二氧化碳升高引起的心脏高交感 tone的影响
Sae Uchida,Fusako Kagitani,Nobuhiro Watanabe et al.
Sae Uchida et al.
This study examined whether the sympatho-inhibitory response of the heart to acupuncture-like stimulation of a hindlimb in anesthetized rats depends on the sympathetic tone. Observed reductions in both cardiac sympathetic nerve activity and...
Exercise does not increase cyclooxygenase-2 myocardial levels in young or senescent hearts [0.03%]
运动不会增加年轻或衰老心脏中的环氧合酶-2水平
John C Quindry,Joel French,Karyn L Hamilton et al.
John C Quindry et al.
Increased myocardial cyclooxygenase-2 (COX-2) activity is essential for late phase ischemic preconditioning (IPC). Currently unknown is whether cardioprotection elicited by exercise also involves elevated myocardial COX-2 activity. This inv...
Effects of repeated lengthening contractions on skeletal muscle adaptations in female rats [0.03%]
重复牵张收缩对雌性大鼠骨骼肌适应的影响
Mark E T Willems,Gerald R Miller,Francoise D Stauber et al.
Mark E T Willems et al.
We examined the adaptation of plantar flexor muscles of female rats to 6 weeks (5 days/week) of lengthening contractions. After repeated lengthening contractions, a decrease in myofiber area of gastrocnemius medialis (26%) was accompanied b...
Electrophysiological and contractile evidence of the ability of human mesenchymal stromal cells to correct vascular malfunction in rats after ionizing irradiation [0.03%]
人间充质干细胞通过电生理和收缩功能实验证明能够纠正离子辐射大鼠后的血管异常
Anatoly Soloviev,Igor Prudnikov,Vladimir Tsyvkin et al.
Anatoly Soloviev et al.
The effect of intravenous administration of human mesenchymal stromal stem cells (hMSC) has been evaluated by means of large-conductance calcium-dependent potassium channel (BK(Ca)) activity measurements in thoracic aorta smooth muscle cell...
Effects of superior colliculus ablation on the air-righting reflex in the rat [0.03%]
关于毁坏顶盖对大鼠空气支持反射的影响作用

Xinping Yan
To examine how the superior colliculus, the motor center of orientation and avoidance, could interact with postural reflexes, we investigated effects of unilateral and bilateral ablations on air-righting reflex movements in otherwise intact...
Estrogen modulates central and peripheral responses to cold in female rats [0.03%]
雌激素调节大鼠对寒冷的中枢和外周反应
Yuki Uchida,Masumi Kano,Saki Yasuhara et al.
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...
