Photodynamic therapy (PDT) has been extensively investigated for decades for tumor
treatment because of its non-invasiveness, spatiotemporal selectivity, lower side-effects, and …

Muscle foods and their products are a fundamental part of the human diet. The high protein
content found in muscle foods, as well as the high content of essential amino acids, provides …

Proteins are major targets for radicals and two-electron oxidants in biological systems due to
their abundance and high rate constants for reaction. With highly reactive radicals damage …

Exposure of biological molecules to oxidants is inevitable and therefore commonplace.
Oxidative stress in cells arises from both external agents and endogenous processes that …

Chemically modified biomacromolecules─ ie, proteins, nucleic acids, glycans, and lipids─
have become crucial tools in chemical biology. They are extensively used not only to …

Endogenous photosensitizers play a critical role in both beneficial and harmful light-induced
transformations in biological systems. Understanding their mode of action is essential for …

Molecular oxygen, O2, has long provided a cornerstone for studies in chemistry, physics,
and biology. Although the triplet ground state, O2 (X3Σg–), has garnered much attention, the …

Photodynamic therapy (PDT) is a minimally invasive therapeutic modality used for the
management of a variety of cancers and benign diseases. The destruction of unwanted cells …

Human skin exposed to solar ultraviolet radiation (UVR) results in a dramatic increase in the
production of reactive oxygen species (ROS). The sudden increase in ROS shifts the natural …

Protein oxidation, a phenomenon that was not well recognized previously but now better
understood, is a complex chemical process occurring ubiquitously in food systems and can …
