Background: To explore the role of zinc (Zn) in cellular physiology it is important to be able to control and quantify the level of Zn contamination in experimental solutions. A technique that relies on a Zn-sensitive flu...
Heart rate variability and short duration spaceflight: relationship to post-flight orthostatic intolerance [0.03%]
心率变异性与短期太空飞行：与飞行后直立不耐受的关系

Andrew P Blaber
Background: Upon return from space many astronauts experience symptoms of orthostatic intolerance. Research has implicated altered autonomic cardiovascular regulation due to spaceflight with further evidence to suggest th...
Human cortical perfusion and the arterial pulse: a near-infrared spectroscopy study [0.03%]
近红外光谱研究中的皮层血流与动脉搏动的关系
Hon C Kwan,Anita Cheng,Ruth Liu et al.
Hon C Kwan et al.
Background: The pulsatile nature of the arterial pulse induces a pulsatile perfusion pattern which can be observed in human cerebral cortex with non-invasive near-infrared spectroscopy. The present study attempts to estab...
Physiological studies in heterozygous calcium sensing receptor (CaSR) gene-ablated mice confirm that the CaSR regulates calcitonin release in vivo [0.03%]
生理研究发现钙敏感受体基因的杂合子敲除小鼠确认了钙敏感受体在体内调控降钙素的释放作用
Neva J Fudge,Christopher S Kovacs
Neva J Fudge
Background: The calcium sensing receptor (CaSR) regulates serum calcium by suppressing secretion of parathyroid hormone; it also regulates renal tubular calcium excretion. Inactivating mutations of CaSR raise serum calciu...

Some processes of energy saving and expenditure occurring during ethanol perfusion in the isolated liver of fed rats; a Nuclear Magnetic Resonance study [0.03%]
喂养大鼠肝隔离乙醇灌流过程中节能和耗能的一些过程；核磁共振研究
Marie-Christine Beauvieux,Patrice Couzigou,Henri Gin et al.
Marie-Christine Beauvieux et al.
Background: In the isolated liver of fed rats, a 10 mM ethanol perfusion rapidly induced a rapid 25% decrease in the total ATP content, the new steady state resulting from both synthesis and consumption. The in situ rate ...

Jian-Wei Gu et al.
Background: Physical inactivity increases the risk of atherosclerosis. However, the molecular mechanisms of this relation are poorly understood. A recent report indicates that endostatin, an endogenous angiostatic factor,...

Background: Rat liver endosomes contain activated insulin receptors and downstream signal transduction molecules. We undertook these studies to determine whether endosomes also contain heterotrimeric G proteins that may b...
Delayed leukocytosis after hard strength and endurance exercise: aspects of regulatory mechanisms [0.03%]
高强度力量和耐力运动后的延迟性白细胞增多及其调节机制
Bjørn Audun Risøy,Truls Raastad,Jostein Hallén et al.
Bjørn Audun Risøy et al.
Background: During infections, polymorphonuclear neutrophilic granulocytes (PMN) are mobilized from their bone marrow stores, travel with blood to the affected tissue, and kill invading microbes there. The signal(s) from ...
Regulation of amylin release from cultured rabbit gastric fundic mucosal cells [0.03%]
调节培养的兔胃底黏膜细胞中酰素的释放
Ian L P Beales,John Calam
Ian L P Beales
Background: Amylin (islet amyloid polypeptide) is a hormone with suggested roles in the regulation of glucose homeostasis, gastric motor and secretory function and gastroprotection. In the gastric mucosa amylin is found c...
Single amino acids in the carboxyl terminal domain of aquaporin-1 contribute to cGMP-dependent ion channel activation [0.03%]
单羧基末端结构域氨基酸对cGMP激活离子通道的贡献作用
Daniela Boassa,Andrea J Yool
Daniela Boassa
Background: Aquaporin-1 (AQP1) functions as an osmotic water channel and a gated cation channel. Activation of the AQP1 ion conductance by intracellular cGMP was hypothesized to involve the carboxyl (C-) terminus, based o...
