Oxidative damage can have a devastating effect on the structure and activity of proteins, and
may even lead to cell death. The sulfur-containing amino acids cysteine and methionine are …

Free radicals and other reactive species (RS) are thought to play an important role in many
human diseases. Establishing their precise role requires the ability to measure them and the …

Proteins are a major target for oxidants as a result of their abundance in biological systems,
and their high rate constants for reaction. Kinetic data for a number of radicals and non …

The thioredoxin (Trx) system is one of the central antioxidant systems in mammalian cells,
maintaining a reducing environment by catalyzing electron flux from nicotinamide adenine …

Amyloid β-peptide (Aβ) is heavily deposited in the brains of Alzheimer's disease (AD)
patients, and free radical oxidative stress, particularly of neuronal lipids and proteins, is …

Chiral structures profoundly influence chemical and biological processes. While chiral
carbon biomolecules have received much attention, chirality is also possible in certain sulfur …

Biological aging is a fundamental process that represents the major risk factor with respect
to the development of cancer, neurodegenerative, and cardiovascular diseases in …

Proteins are continuously affected by various intrinsic and extrinsic factors. Damaged
proteins influence several intracellular pathways and result in different disorders and …

Reactive oxygen species (ROS) are generated during normal cellular activity and may exist
in excess in some pathophysiological conditions, such as inflammation or reperfusion injury …

Staphylococci are a versatile genus of bacteria that are capable of causing acute and
chronic infections in diverse host species. The success of staphylococci as pathogens is due …
