Distribution of serotonergic and dopaminergic nerve fibers in the salivary gland complex of the cockroach Periplaneta americana [0.03%]
美洲蟑螂唾液腺中的五羟色胺能和多巴胺能神经纤维的分布
Otto Baumann,Petra Dames,Dana Kühnel et al.
Otto Baumann et al.
Background: The cockroach salivary gland consists of secretory acini with peripheral ion-transporting cells and central protein-producing cells, an extensive duct system, and a pair of reservoirs. Salivation is controlled...
Regional differences in expression of VEGF mRNA in rat gastrocnemius following 1 hr exercise or electrical stimulation [0.03%]
大鼠腓肠肌血管内皮生长因子mRNA表达的地域性差异及其与运动和电刺激的关系
Tom D Brutsaert,Timothy P Gavin,Zhenxing Fu et al.
Tom D Brutsaert et al.
Background: Vascular endothelial growth factor (VEGF) mRNA levels increase in rat skeletal muscle after a single bout of acute exercise. We assessed regional differences in VEGF165 mRNA levels in rat gastrocnemius muscle ...
Activation of the kinin system in the ovary during ovulation: role of endogenous progesterone [0.03%]
排卵期间卵巢激肽释放系统的激活及其内源性孕酮的作用
Darrell W Brann,Lowell M Greenbaum,Virendra B Mahesh et al.
Darrell W Brann et al.
Background: Previous work by our group and others has implicated a role for kinins in the ovulatory process. The purpose of the present study was to elucidate whether endogenous progesterone, which is an intraovarian regu...
Ian J Newhouse,Kris P Johnson,William J Montelpare et al.
Ian J Newhouse et al.
Background: With the invention of the ion-selective electrode (ISE), ionic magnesium (iMg) is a common blood assay. This could be advantageous, as iMg is the biologically active form of Mg. There is some evidence that iMg...
Detection of fast light-activated H+ release and M intermediate formation from proteorhodopsin [0.03%]
利用生理记录技术检测到视紫红质快速释放H+及中间体M的状态
Richard A Krebs,Ulrike Alexiev,Ranga Partha et al.
Richard A Krebs et al.
Background: Proteorhodopsin (pR) is a light-activated proton pump homologous to bacteriorhodopsin and recently discovered in oceanic gamma-proteobacteria. One perplexing difference between these two proteins is the absenc...

Background: Blood leukocytes constitute two interchangeable sub-populations, the marginated and circulating pools. These two sub-compartments are found in normal conditions and are potentially affected by non-normal situa...
Tetraethylammonium block of water flux in Aquaporin-1 channels expressed in kidney thin limbs of Henle's loop and a kidney-derived cell line [0.03%]
四乙胺能阻断肾髓袢薄段和肾衍生细胞系的Aquaporin-1通道中的水通量
Andrea J Yool,Olga H Brokl,Thomas L Pannabecker et al.
Andrea J Yool et al.
Background: Aquaporin-1 (AQP1) channels are constitutively active water channels that allow rapid transmembrane osmotic water flux, and also serve as cyclic-GMP-gated ion channels. Tetraethylammonium chloride (TEA; 0.05 t...
Blockade of maitotoxin-induced oncotic cell death reveals zeiosis [0.03%]
妙毒诱导的 oncotic 细胞死亡的阻断揭示了 zeiosis 现象
Mark Estacion,William P Schilling
Mark Estacion
Background: Maitotoxin (MTX) initiates cell death by sequentially activating 1) Ca2+ influx via non-selective cation channels, 2) uptake of vital dyes via formation of large pores, and 3) release of lactate dehydrogenase,...
Adaptations to iron deficiency: cardiac functional responsiveness to norepinephrine, arterial remodeling, and the effect of beta-blockade on cardiac hypertrophy [0.03%]
缺铁的适应：肾上腺素能药物 NE的心脏功能反应性、动脉重塑以及β-受体阻滞剂对心脏肥大的影响
Lexa Rae Turner,Daniel Aaron Premo,Brett Jason Gibbs et al.
Lexa Rae Turner et al.
Background: Iron deficiency (ID) results in ventricular hypertrophy, believed to involve sympathetic stimulation. We hypothesized that with ID 1) intravenous norepinephrine would alter heart rate (HR) and contractility, 2...
Functional analysis of a frame-shift mutant of the dihydropyridine receptor pore subunit (alpha1S) expressing two complementary protein fragments [0.03%]
功能性分析α1S通道亚单位的无义突变型及表达两种互补蛋白片段的研究
C A Ahern,P Vallejo,L Mortenson et al.
C A Ahern et al.
Background: The L-type Ca2+ channel formed by the dihydropyridine receptor (DHPR) of skeletal muscle senses the membrane voltage and opens the ryanodine receptor (RyR1). This channel-to-channel coupling is essential for C...
