Remote ischemic preconditioning-induced late cardioprotection: possible role of melatonin-mitoKATP-H2S signaling pathway

Acta cir. bras; 38 (), 2023
Purpose: Remote ischemic preconditioning (RIPC) confers cardioprotection against ischemia reperfusion (IR) injury. However, the precise mechanisms involved in RIPC-induced cardioprotection are not fully explored. The present study was aimed to identify the role of melatonin in RIPC-induced late cardiopro...

Protective effects of melatonin in cisplatin-induced cardiac toxicity: possible role of BDNF-TNF-α signaling pathway

Acta cir. bras; 37 (2), 2022
Purpose: The present study explored the role of melatonin in cisplatin-induced cardiac injury along with the possible role of brain-derived neurotrophic factor (BDNF) in melatonin-mediated effects. Methods: Wistar rats were administered cisplatin (10 mg/kg), and cardiac injury was assessed by measuring ...

Acutely applied melatonin prevents CCl4-induced testicular lesions in rats: the involvement of the oxidative capacity and arginine metabolism

Abstract Carbon tetrachloride (CCl4) represents an organic chemical that causes reactive oxygen species derived organ disturbances including male infertility. Melatonin (MLT) is a neurohormone with strong antioxidant capacity, involved in numerous physiological processes. In this study we evaluated the c...

Melatonin and its neuroimmunological actions

Introduction: Melatonin is a neurohormone, synthesized mainly in the pineal gland, which regulates the circadian rhythm. Objective: To describe the neuroimmunological actions produced by melatonin. Methods: A review on the subject was carried out using articles of free access in the Pubmed database ...

Comparison of sexual performance and testicular characteristics of melatonin treated Kivircik and Charollais rams during the non-breeding season

This study was conducted to investigate the effects of melatonin implantation on basic testicular characteristics and reproductive performance of Kivircik and Charollais rams and ewes during the non-breeding season. In this study, 8 Kivircik and 6 Charollais rams were used. Rams were implanted with 54 mg...

Efeito de diferentes concentrações de melatonina em espermatozoides de carneiros sobre estresse oxidativo após criopreservação

Pesqui. vet. bras; 36 (7), 2016
Objetivou-se avaliar o efeito da adição de diferentes concentrações de melatonina no sêmen diluído de carneiros após criopreservação. Foram coletados 10 ejaculados de três carneiros adultos (n=30), por meio de vagina artificial para ovinos. Os ejaculados coletados foram diluídos em Tris-Gema d...
