Direct evidence of singlet molecular oxygen [O2 (1Δg)] production from UVA excited 6‐thioguanine

Photochemistry and Photobiology, EarlyView.
6‐Thioguanine (6‐TGua) is incorporated into DNA as a purine analogue, inhibiting cell replication. Patients treated with 6‐TGua are more prone to developing skin cancer due to the photoexcitation of 6‐TGua by UVA radiation (as illustrated in the Jablonski diagram). Upon exposure to UVA, the excited 6‐TGua generates 1O2.

RAD51 and RAD51 paralog inhibition sensitizes nonreplicating quiescent keratinocytes to UV radiation

Photochemistry and Photobiology, EarlyView.
UV radiation and other compounds generate DNA adducts that block transcription and induce cell death if not removed by the nucleotide excision repair system. In this work, we used a small‐scale pharmacological screen to discover that inhibition of the recombinase RAD51 sensitized nonreplicating quiescent keratinocytes to both UVR and other agents that ...

Alternation of must, have to, and need to in English as a lingua franca

World Englishes, EarlyView.
Abstract This study explores the grammatical variability of modal auxiliary verbs in English as a lingua franca. Focusing on the ongoing change must, have to, and need to, this research utilizes two spoken corpora: the Vienna–Oxford International Corpus of English (VOICE) and the Asian Corpus of English (ACE).
