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 …

Ultraviolet (UV) light induces specific mutations in the cellular and skin genome such as UV-
signature and triplet mutations, the mechanism of which has been thought to involve …

A procedure for a detailed analysis of excited states in systems of interacting chromophores
is proposed. By considering the one-electron transition density matrix, a wealth of …

Hyaluronic acid (HA) is a glycosaminoglycan that is found in extracellular tissue in many
parts of the body. It is a material of increasing importance to biomaterials science and is …

Biochemical reactions are subject to the particular environmental conditions of planet earth,
including solar irradiation. How DNA responds to radiation is relevant to human health …

This review chapter presents a critical survey of the main available information on the UVB
and UVA bipyrimidine photoproducts which constitute the predominant recipient classes of …

During the last 10 years, intense experimental and theoretical work has proven the
existence of ultrafast nonradiative decay routes for UV-excited monomeric nucleic acid …

The study addresses interconnected issues related to two major types of cycloadditions
between adjacent thymines in DNA leading to cyclobutane dimers (T<> Ts) and (6-4) …

The knowledge of the fundamental processes induced by the direct absorption of UV
radiation by DNA allows extrapolating conclusions drawn from in vitro studies to the in‐vivo …

DNA damage induced by photosensitization is not only responsible for the genotoxic effects
of various types of drugs in the presence of light, but is also relevant for some of the adverse …
