Rat isolated atria and ventricles release endothelium-derived 6-nitrodopamine, which induces potent positive chronotropic and inotropic responses. 6-Cyanodopamine is released from rabbit isolated atria and ventricles; however, it is not known whether this novel catecholamine has any action on the isolated heart. Therefore, it was investigated whether rat isolated ventricles release 6-cyanodopamine and its action on the rat isolated heart.

Despite the implications of increased gleaf-res for species survival under hotter-drought conditions, little is known about the dynamics of gleaf-res variation after heatwave episodes. Here, we examined the gleaf-res variation before, during, and after exposure to high temperatures (HTs) in a group of representative Cerrado tree species.

Although experiments examining the warming effects on photosynthetic and respiratory thermal acclimation have been widely conducted, the sensitivity of various ecosystem and vegetation types to warming remains uncertain. Here we conducted a meta-analysis on experimental observations of thermal acclimation worldwide.

The aim of this review was to analyze oncological and functional outcomes of NeuroSAFE.
Methods: A systematic search of the Medline, Embase, and Web of Science databases until July 2024 was performed.
Background And Aims: Tropical forests exchange more carbon dioxide (CO2) with the atmosphere than any other terrestrial biome. Yet, uncertainty in the projected carbon balance over the next century is roughly three-times greater for the tropics than other ecosystems. Our limited knowledge of tropical plant physiological responses, including photosynthetic, to climate change is a substantial source of uncertainty in our ability to forecast the global terrestrial carbon sink.
