Masayoshi Takamori et al.
The purpose of this study was the detection and characterization of synergistic muscle activity. Using T2-map MRI, T2 values for 10 forearm muscles in 11 healthy adult volunteers were obtained in the resting state and after isotonic forearm...
Microglia mediate the increase in slow-wave sleep associated with high ambient temperature [0.03%]
小胶质细胞介导环境高温诱发的慢波睡眠增多现象

Intraocular pressure (IOP) plays a crucial role in glaucoma development, involving the dynamics of aqueous humor (AH). AH flows in from the ciliary body and exits through the trabecular meshwork (TM). IOP follows a circadian rhythm synchron...
Alteration of serotonin release response in the central nucleus of the amygdala to noxious and non-noxious mechanical stimulation in a neuropathic pain model rat [0.03%]
坐骨神经损伤大鼠模型中央杏仁核血清素释放反应的改变

Previously, we found that serotonin (5-HT) release in the central nucleus of the amygdala (CeA) of anesthetized rats decreases in response to innocuous stroking of the skin, irrespective of stimulus laterality, but increases in response to ...
Influence of age on nicotinic cholinergic regulation of blood flow in rat's olfactory bulb and neocortex [0.03%]
年龄对尼古丁胆碱能调节大鼠嗅球和新皮质血流量的影响

The olfactory bulb receives cholinergic basal forebrain inputs as does the neocortex. With a focus on nicotinic acetylcholine receptors (nAChRs), this review article provides an overview and discussion of the following findings: (1) the nAC...
Regulation of myocardial contraction as revealed by intracellular Ca2+ measurements using aequorin [0.03%]
用aequorin测定细胞内Ca2+浓度对心肌收缩的调节研究
Satoshi Kurihara,Norio Fukuda
Satoshi Kurihara
Of the ions involved in myocardial function, Ca2+ is the most important. Ca2+ is crucial to the process that allows myocardium to repeatedly contract and relax in a well-organized fashion; it is the process called excitation-contraction cou...
Identification of hypothermia-inducing neurons in the preoptic area and activation of them by isoflurane anesthesia and central injection of adenosine [0.03%]
视前区致低体温神经元的鉴定及异氟醚吸入和腺苷中枢注射激活该神经元的作用
