Environmental noise induces the release of stress hormones and inflammatory signaling molecules leading to oxidative stress and vascular dysfunction-Signatures of the internal exposome.

Biofactors 2019 Apr 2. Epub 2019 Apr 2.

Department of Cardiology 1, Center for Cardiology, Mainz, Germany.

Environmental noise is a well-recognized health risk and part of the external exposome-the World Health Organization estimates that 1 million healthy life years are lost annually in Western Europe alone due to noise-related complications, including increased incidence of hypertension, heart failure, myocardial infarction, and stroke. Previous data suggest that noise works through two paired pathways in a proposed reaction model for noise exposure. As a nonspecific stressor, chronic low-level noise exposure can cause a disruption of sleep and communication leading to annoyance and subsequent sympathetic and endocrine stress responses leading to increased blood pressure, heart rate, stress hormone levels, and in particular more oxidative stress, being responsible for vascular dysfunction and representing changes of the internal exposome.

Neural Activation During Visual Attention Differs in Individuals with High versus Low Macular Pigment Density.

Mol Nutr Food Res 2019 Mar 28:e1801052. Epub 2019 Mar 28.

Vision Sciences Laboratory, Behavioral and Brain Sciences Program, Department of Psychology, The University of Georgia, Athens, GA, 30602, USA.

Scope: The neural efficiency hypothesis for lutein (L) and zeaxanthin (Z) suggests that higher levels of L+Z in the central nervous system (CNS) are predictive of stronger stimulus-specific brain responses. Past research suggests that supplementing L+Z can improve neural processing speed and cognitive function across multiple domains, which supports this hypothesis. The purpose of this study is to determine the extent to which CNS L+Z levels predict brain responses using an attentionally taxing task. Read More

Glutathione compartmentalization and its role in glutathionylation and other regulatory processes of cellular pathways.

Biofactors 2019 Mar 18;45(2):152-168. Epub 2018 Dec 18.

Department of Clinical Sciences, Section of Biochemistry, Biology and Physics, Università Politecnica delle Marche, Ancona, Italy.

Glutathione is considered the major non-protein low molecular weight modulator of redox processes and the most important thiol reducing agent of the cell. The biosynthesis of glutathione occurs in the cytosol from its constituent amino acids, but this tripeptide is also present in the most important cellular districts, such as mitochondria, nucleus, and endoplasmic reticulum, thus playing a central role in several metabolic pathways and cytoprotection mechanisms. Indeed, glutathione is involved in the modulation of various cellular processes and, not by chance, it is a ubiquitous determinant for redox signaling, xenobiotic detoxification, and regulation of cell cycle and death programs.
