In this study, we show that IL-1beta processing and secretion induced by pathogen-associated molecular pattern (PAMP) molecules in human monocytes is regulated by a biphasic redox event including a prompt oxidative stress and a delayed antioxidant response. Namely, PAMPs induce an early generation of reactive oxygen species (ROS) followed by increase of intracellular thioredoxin and release of ...

background & aim: achillea (fam. asteraceae) is a medicinal plant and different species of it have several uses in the folk medicine all around the world. achillea species are used for feverish conditions, common cold, digestive complaints, slow healing wounds and skin inflammations. this study aims to investigate the essential oil composition and antioxidant activities from the aerial part...

Introduction The antioxidant capabilities of foods, cosmetics, supplements and pharmaceutical agents has become of particular interest. This is the result of the evidence demonstrating the relationship of reactive oxygen/nitrogen species (ROS) with aging and pathogenesis. [1,2]. Living organisms: use of a fuel (ATP) whose production results in the formation of toxic compounds, and requires that...

Rhodomyrtus tomentosa (Myrtaceae) has been employed in traditional Thai medicine to treat colic diarrhoea, dysentery, abscesses, haemorrhage, and gynaecopathy. In addition, it has been used to formulate skin-whitening, anti-aging and skin beautifying agents. Ethnomedical activities of this plant may be due its antioxidant property. Hence, the aim of this study was to evaluate both in vitro and ...
