The origins and actions of gaseous signaling molecules, nitric oxide (NO), carbon monoxide
(CO) and hydrogen sulfide (H2S) in the mammalian cardiovascular system have received …

Publisher Summary The cardiorespiratory system in fish, as in other vertebrates, functions to
meet the metabolic requirements of the cells for O 2 and to remove the CO 2 produced by …

The physiological diversity of blood oxygen transport traits in fishes appears designed to
maintain tissue oxygenation under challenges from both metabolic demand and …

Environmental shifts accompanying salmon spawning migrations from ocean feeding
grounds to natal freshwater streams can be severe, with the underlying stress often cited as …

The liver is an essential energy storage organ in vertebrates. In teleosts and elasmobranchs,
previous studies examining hepatic energy balance have used isolated hepatocytes …

Nitric oxide (NO), produced by nitric oxide synthases (NOS enzymes), regulates multiple
physiological functions in animals. NO exerts its effects by binding to iron (Fe) of heme …

Nitric oxide is one of the most important signalling molecules involved in the regulation of
physiological function. It first came to prominence when it was discovered that the vascular …
