To what extent sildenafil, a selective inhibitor of the type-5 phosphodiesterase modulates systemic redox status and cerebrovascular function during acute exposure to hypoxia remains unknown. To address this, 12 healthy males (aged 24 ± 3 y) participated in a randomized, placebo-controlled crossover study involving exposure to both normoxia and acute (60 min) hypoxia (Fi = 0.14), followed by oral administration of 50 mg sildenafil and placebo (double-blinded).

Bisphenol A (BPA) is a hazardous endocrine disruptor released into the environment during the production of certain plastics used for covering of food and beverage cans. In this work, we examined the protective benefits of selenium (Se) against intestinal damage induced by BPA in male rats. Rats were distributed randomly into four groups.

Cold acclimation and vernalization represent the major evolutionary adaptive responses to ensure winter survival of temperate plants. Due to climate change, mild winters can paradoxically worsen plant winter survival due to cold deacclimation induced by warm periods during winter. It seems that the ability of cold reacclimation in overwintering Triticeae cereals is limited, especially in vernalized plants.

Oocyte aging is closely related to a decline in female fertility, accompanied by increased reactive oxygen species levels and changes in protein posttranslational modifications. However, the role of protein palmitoylation in oocyte aging has not been investigated. In the present study, a new association between redox and palmitoylation in aging oocytes was found.
