Singlet oxygen (1O2) is a biologically relevant reactive oxygen species capable of efficiently
reacting with cellular constituents. The resulting oxidatively generated damage to nucleic …

UV-induced DNA damage plays a key role in the initiation phase of skin cancer. When left
unrepaired or when damaged cells are not eliminated by apoptosis, DNA lesions express …

Emphasis has been placed in this article dedicated to DNA damage on recent aspects of the
formation and measurement of oxidatively generated damage in cellular DNA in order to …

Photodynamic therapy (PDT) is a clinical modality used to treat cancer and infectious
diseases. The main agent is the photosensitizer (PS), which is excited by light and converted …

Telomeres are essential for genome stability. Oxidative stress caused by excess reactive
oxygen species (ROS) accelerates telomere shortening. Although telomeres are …

Photosensitization reactions have been demonstrated to be largely responsible for the
deleterious biological effects of UV and visible radiation, as well as for the curative actions of …

In this review article, emphasis is placed on the critical survey of available data concerning
modified nucleobase and 2-deoxyribose products that have been identified in cellular DNA …

Multifunctional antibacterial photodynamic therapy is a promising method to combat regular
and multidrug‐resistant bacteria. In this work, eosin Y (EY)‐based antibacterial polycations …

Reactive oxygen species, including singlet oxygen, play an important role in the onset and
progression of disease, as well as in aging. Singlet oxygen can be formed non …

This review article focuses on a critical survey of the main available information on the UVB
and UVA oxidative reactions to cellular DNA as the result of direct interactions of UV …
