Recognition in action: flipping pyrimidine dimers [PDF]
Journal of Molecular Recognition, 2005 DNA bases are normally sheltered within a double helix, but enzymes that modify and repair DNA gain access by flipping individual bases out of the double helix.

Advanced Science, EarlyView.Light‐switchable MSCs (MSC‐UCNPs) were constructed by intracellular incorporation of UCNPs. Upon 980 nm irradiation, UCNPs emitted localized ultraviolet light (365 nm), activating the ROS/HEXB/LAMP1 signaling pathway to suppress lysosome–multivesicular body fusion and thereby enhance exosome biogenesis. Embedded within an injectable hydrogel, MSC‐UCNPs

Angewandte Chemie International Edition, EarlyView.In many Pd‐catalyzed cross‐couplings, catalyst performance has been found to be limited by catalyst activation. Methylnaphthyl (MeNAP) palladium trifluoroacetate dimers are presented as easy‐to‐store and easy‐to‐handle precursors, which rapidly activate under reaction conditions, even when only weakly coordinating, non‐reducing nucleophiles are present.

Evidence for Excision of Ultraviolet-Induced Pyrimidine Dimers from the DNA of Human Cells In Vitro
, 1968 Within 12–24 hr after human cells were irradiated with ultraviolet light, approximately 50% of the ultraviolet-induced pyrimidine dimers were lost from the DNA.

Studies on the Mechanism of the Photosensitized Dimerization of Pyrimidines
Zeitschrift für Naturforschung B, 1972 Thymine-2-14C was irradiated with UV light (>300 nm) in water solutions in the presence of different sensitizers. Pyrimidines upon irradiation with wavelengths of 300—320 nm in the presence of some ketones as sensitizers, yield cyclobutyl pyrimidine dimers.

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy
BMEMat, EarlyView.Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...
