Part of the life cycle of several fish species includes important salinity changes, as is the
case for the sea bass (Dicentrarchus labrax) or the Atlantic salmon (Salmo salar). Salmo …

Melatonin, an endogenous indolamine derived from tryptophan, is primarily synthesized by
the pineal gland in mammals and regulated by a complex neural system. Its release follows …

Objectives The aim of this study was to verify whether a single oral dose of gabapentin (100
mg) or melatonin (3 mg) given 60 mins before a cardiac evaluation would reduce anxiety …

In seasonally breeding mammals and birds, the production of the hormones that regulate
reproduction (gonadotropins) is controlled by a complex pituitary-brain-pituitary pathway …

Repeated or chronic stress can change the phase of peripheral circadian rhythms.
Melatonin (Mel) is thought to be a circadian clock-controlled signal that might play a role in …

In the last two decades, kisspeptin (Kiss) has been identified as an important player in the
regulation of reproduction and other physiological functions in vertebrates, including several …

Melatonin (MT) is a crucial neuroendocrine regulator of various physiological activities in
vertebrates, especially in circadian or seasonal rhythm control. In the present study, the …

Fishes exhibit rhythmic activities synchronized by the cyclic variations in the external
environment. Reproduction is one of those rhythmic processes that require precise timing …

Abstract Neuregulin‐4 (Nrg4) and melatonin play vital roles in endocrine diseases.
However, there is little discussion about the function and potential mechanism of Nrg4 and …

In vertebrates, pituitary gonadotropins (follicle-stimulating and luteinizing hormones: FSH
and LH) regulate gonadal development and maturation, therefore playing an essential role …
