Background & Aim: When the level of free radicals is increased and also when both the enzymatic systems and low molecular antioxidants are not sufficient to protect the organism, it seems necessary to get antioxidants from external sources. This study aimed to evaluate the antioxidant potential of different parts of Catharantus roseus Experimental: The antioxidant potential of ethanol...

The invasive macroalga Grateloupia turuturu is known to contain a diversity of bioactive compounds with different potentialities. Among them are relevant bioactivities for cosmetics. Considering this, this study aimed screen cosmeceutical potential, namely, antioxidant, UV absorbance, anti-enzymatic, antimicrobial, and anti-inflammatory activities, as well photoprotection potential. Extractions...

We investigated the effects of thyroid state on mechanisms underlying rat heart mitochondrial capacity to remove H2O2 produced by an exogenous source. The removal rates were higher in presence respiratory substrates independently from and hyperthyroid than hypothyroid preparations. state-linked changes rates, mirrored those release showing that endogenous do not compete for removing system. Mit...
