Control of cerebral cortical blood flow by stimulation of basal forebrain cholinergic areas in mice [0.03%]
刺激基底前脑胆碱能区域对小鼠大脑皮质血流的调节作用
Harumi Hotta,Sae Uchida,Fusako Kagitani et al.
Harumi Hotta et al.
We examined whether activity of the nucleus basalis of Meynert (NBM) regulates regional cerebral cortical blood flow (rCBF) in mice, using laser speckle and laser Doppler flowmetry. In anesthetized mice, unilateral focal stimulation, either...
Inositol 1, 4, 5-trisphosphate receptor interacts with the SNARE domain of syntaxin 1B [0.03%]
肌醇1,4,5-三磷酸受体与syntaxin 1B的SNARE结构域相互作用
Sayaka Tanaka,Hiroyuki Kabayama,Masahiro Enomoto et al.
Sayaka Tanaka et al.
Inositol 1, 4, 5-trisphosphate receptors (IP(3)Rs) are intracellular ligand-gated Ca(2+) channels that mediate Ca(2+) release from the endoplasmic reticulum (ER) into the cytosol and function in diverse cellular processes including fertiliz...
Development of synchrony between activity patterns of mother-infant pair from 4 to 18 months after birth [0.03%]
婴儿出生后从4个月到18个月与母亲互动的同步性发展的变化规律研究
Hirokazu Doi,Mikako Kato,Shota Nishitani et al.
Hirokazu Doi et al.
Motor activities of interacting agents get temporally coordinated to form synchronized actions. Such activity synchrony is observed in several mammalian species and is supposed to play vital roles in human social interactions. Therefore, it...
The role of alpha adrenoceptors in the vascular and estradiol secretory responses to stimulation of the superior ovarian nerve [0.03%]
Superior卵巢神经刺激对血管和雌二醇分泌反应中肾上腺素受体的作用

Fusako Kagitani
Electrical stimulation of the superior ovarian nerve in rats reduces both the plasma flow rate of ovarian venous blood (ovarian blood flow) and the ovarian estradiol secretion rate. Here, we examined the possible roles of alpha-adrenoceptor...
Human urate transporter 1 (hURAT1) mediates the transport of orotate [0.03%]
人类尿酸转运蛋白1（hURAT1）介导次黄嘌呤单核苷酸（或otate）的转运
Daisaku Miura,Naohiko Anzai,Promsuk Jutabha et al.
Daisaku Miura et al.
Orotate is a precursor of pyrimidine synthesis. The kidney uses exogenous orotate for the synthesis of uridine diphosphosugars, which are used in the glycosylation of collagen in glomerular and tubular basement membranes. Orotate uptake occ...
Progressive arteriolar vasoconstriction and fatigue during tetanic contractions of rat skeletal muscle are inhibited by α-receptor blockade [0.03%]
α肾上腺素受体阻断剂可抑制大鼠骨骼肌 tetanus收缩时的动脉血管收缩和疲劳发生率
Tadakatsu Inagaki,Takashi Sonobe,David C Poole et al.
Tadakatsu Inagaki et al.
Voluntary muscle contractions activate sympathetic efferent pathways. Using a fatiguing electrical stimulation protocol designed specifically to enhance sympathetically-mediated vasoconstrictor tone, we explored the temporal profile and mec...
DNA microarray profiling identified a new role of growth hormone in vascular remodeling of rat ductus arteriosus [0.03%]
DNA微阵列谱型分析鉴定出生长激素在大鼠动脉导管血管重塑中的新作用
Mei-Hua Jin,Utako Yokoyama,Yoji Sato et al.
Mei-Hua Jin et al.
The ductus arteriosus (DA), a fetal arterial connection between the pulmonary artery and the aorta, has a character distinct from the adjacent arteries. We compared the transcriptional profiles of the DA and the aorta of Wistar rat fetuses ...

Takeshi Kobayashi et al.
Although many researchers have tried to observe the beginning of the heartbeat, no study has shown the beginning of the calcium transient. Here, we evaluate the beginning of the calcium transient in the Wistar rat heart. We first tried to r...
Fractal properties of postural sway during quiet stance with changed visual and proprioceptive inputs [0.03%]
视觉和本体感受输入变化时静立平衡的分形性质分析

We studied the fractal dynamics of postural sway during quiet stance with changed visual and/or proprioceptive information. Radius-vector length and angle of rotation of center of foot pressure (COP) displacements were used as parameters of...
The relationship between aortic baroreceptor activity and arterial pressure is not monotonic [0.03%]
主动脉压力感受活性与动脉血压之间的关系并非单一的函数关系
Chris P Bolter,Michael J Turner,Carolyn J Barrett
Chris P Bolter
Previous reports indicate that when aortic pressure (AP) falls below the threshold (P (th)) for baroreceptor sensitivity, activity in the aortic depressor nerve (ADN) may increase. To quantify and explain this anomalous behaviour, we analys...
