Using Lifetime and Quenching Rate Constant to Determine Quencher Concentration [PDF]
, 2022 Excited state quenching is a key step in photochemical reactions that involve energy or electron transfer. High reaction quantum yields require sufficiently high concentrations of quencher to ensure efficient quenching.

Loss of IGF‐1R impairs DNA‐PKcs recruitment to chromatin leading to defective end‐joining
Molecular Oncology, EarlyView.IGF‐1R promotes radioresistance by facilitating DNA‐PKcs recruitment to chromatin, enabling non‐homologous end‐joining (NHEJ) repair of double‐strand breaks. Inhibition or loss of IGF‐1R disrupts this recruitment to damage sites, driving compensatory reliance on microhomology‐mediated end‐joining (MMEJ) repair.

Molecular Oncology, EarlyView.Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

Excitation Energy Transfer and Trapping in Higher Plant Photosystem II Complexes with Different Antenna Sizes [PDF]
, 2011 700 cm(-1)) and a slow relaxation of the radical pair to an irreversible state (similar to 150 ps). Somewhat unexpectedly, we had to reduce the energy-transfer and charge-separation rates in complexes with decreasing size to obtain optimal fits.

Determination of Trace 55Fe and 63Ni in Steel Samples via Liquid Scintillation Counting
Applied SciencesIn the decommissioning of nuclear facilities, activated steel often contains radionuclides such as 55Fe and 63Ni, which are categorized as hard-to-measure due to their emission of only low-energy beta particles or X-rays.
