There are numerous different scenarios in which microorganisms are exposed to highly reactive molecules known as free radicals. These molecules are capable of damaging important cell components and ...

Free radicals are unstable atoms or molecules with free outer electrons. This makes them highly reactive because free electrons always strive to form a stable bond. This stabilization involves gaining ...

Oxidative Stress or oxidative cell damage occurs when there is an accumulation of free radicals. These radicals are harmful oxygen-derived chemicals called reactive oxygen species (ROS). Normally ...

Weill Cornell researchers uncovered how free radicals from astrocyte mitochondria can fuel dementia. Using new compounds that ...

Free radical chemistry centres on the study of species that possess one or more unpaired electrons – a feature that confers unique reactivity and diverse roles across chemical and biological systems.

Cellular respiration is a very efficient process through which a lot of energy is generated from a few sugar molecules and oxygen. However, up to two percent of the oxygen used in this process is ...

Sigma-1 receptors (Sig-1Rs) are endoplasmic reticulum (ER)-resident proteins known to be involved in learning and memory. Dendritic spines in hippocampal neurons play important roles in ...

Free radicals generated at a specific site in non-neuronal brain cells called astrocytes may promote dementia, according to a ...

In vitro treatment of microsomal membranes from the axes of soybean (Glycine max (L.) Merr.) seeds with free radicals simulates the type of membrane injury observed following a lethal desiccation ...

The eminent, controversial, and endlessly inventive biochemist Bruce Ames thinks he has found a way to slow the aging process in the brain. May the force be with him "Getting old is just like getting ...
