Sandra Imbrogno et al.
The reduced availability of dissolved oxygen is a common stressor in aquatic habitats that affects the ability of the heart to ensure tissue oxygen supply. Among key signalling molecules activated during cardiac hypoxic stress, nitric oxide...
A sudden change of heart: Warm acclimation can produce a rapid adjustment of maximum heart rate and cardiac thermal sensitivity in rainbow trout [0.03%]
骤然换心：亲温驯化可以迅速调节虹彩鱼的最大心率和心脏热敏性

Matthew J H Gilbert
Warm acclimation in fish is often characterized by an increase in heat tolerance and a reduction in physiological rates to improve the scope to respond to additional challenges including further warming. The speed of these responses can det...
Acute and chronic cold exposure differentially affect cardiac control, but not cardiorespiratory function, in resting Atlantic salmon (S almo salar) [0.03%]
急性冷暴露和慢性冷暴露对静息状态下大西洋鲑鱼（S almo salar）心脏控制的影响不同，但不会影响其心肺功能

E S Porter et al.
No studies have examined the effects of cold temperatures (∼0-1 °C) on in vivo cardiac function and control, and metabolism, in salmonids. Thus, we examined: 1) how acclimation to 8 °C vs. acclimation (>3 weeks) or acute exposure (8-1 °...
Regulation of cardiac ryanodine receptor function by the cyclic-GMP dependent protein kinase G [0.03%]
蛋白激酶G通过环鸟苷酸调节心肌ryanodine受体功能
Luis A Gonano,Hamish M Aitken-Buck,Akash D Chakraborty et al.
Luis A Gonano et al.
Background: The cGMP-dependent protein kinase G (PKG) phosphorylates the cardiac ryanodine receptor (RyR2) in vitro. We aimed to determine whether modulation of endogenous PKG alters RyR2-mediated spontaneous Ca2+ release...
Developing chicken cardiac muscle mitochondria are resistant to variations in incubation oxygen levels [0.03%]
雏鸡心脏肌肉线粒体抵抗孵育氧浓度变化的影响

Background: Chronic exposure to hypoxia during vertebrate development can produce abnormal cardiovascular morphology and function. The aim of this study was to examine cardiac mitochondria function in an avian model, the ...
The interactive effects of exercise training and functional feeds on the cardiovascular performance of rainbow trout (Oncorhynchus mykiss) at high temperatures [0.03%]
锻炼和功能性饲料对虹彩 trout 心血管性能的交互作用效应及高温影响

Anna Papadopoulou et al.
The cardiovascular performance of salmonids in aquaculture can be impaired by acute climate warming, posing risks for fish survival. Exercise training and functional feeds have been shown to be cardioprotective in mammals but their action o...
Rhythmicity in heart rate and its surges usher a special period of sleep, a likely home for PGO waves [0.03%]
心率的节律性和激增预示着睡眠的一个特殊时期，这里可能是PGO波的重要发生地

High amplitude electroencephalogram (EEG) events, like unitary K-complex (KC), are used to partition sleep into stages and hence define the hypnogram, a key instrument of sleep medicine. Throughout sleep the heart rate (HR) changes, often a...
Effect of thermal variation on the cardiac thermal limits of a eurythermal marine teleost (Girella nigricans) [0.03%]
温度变化对一种广温海水硬骨鱼(Girella nigricans)心脏热极限的影响

Although most animals live in complex, thermally variable environments, the impact of this variability on specific physiological systems is still unresolved. The ectotherm heart is known to change in both structure and function to ensure ap...
Regulation of collagen deposition in the trout heart during thermal acclimation [0.03%]
温度适应过程中调控的鱼类心脏胶原沉积 регулирование отложения коллагена в сердце форели при температурной акклиматизации

The passive mechanical properties of the vertebrate heart are controlled in part by the composition of the extracellular matrix (ECM). Changes in the ECM, caused by increased blood pressure, injury or disease can affect the capacity of the ...
Seasonal changes of electrophysiological heterogeneities in the rainbow trout ventricular myocardium [0.03%]
