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.

Geographic provenance and environmental growing conditions as factors influencing phytochemical composition of Arabica green coffee beans

Plant Biology, EarlyView.
Growth environment strongly influences green coffee bean biochemistry, linking phytochemical composition to adaptation under abiotic stress. Abstract This study explores how bioactive compounds in green coffee beans (Coffea arabica L.) vary across different geographic regions, addressing the key question of how environmental factors shape coffee ...

Analysis of purine in purine-rich cauliflower

Analysis of purine in purine-rich cauliflower
Purine is a general term for purine nucleotides, nucleosides, bases, and nucleic acid. The amount of purine nucleotides, nucleosides, and bases in purine-rich cauliflower was determined with the use of LC-MS and HPLC, and the ratio of these molecules were compared with in raw and in heated condition.

Development and production of allogeneic cord blood‐derived red blood cell concentrates for transfusion to extremely preterm neonates, the All‐Cord study

Transfusion, EarlyView.
Abstract Background Extremely preterm neonates often require red blood cell (RBC) transfusions derived from adult donors. These transfusions introduce adult hemoglobin into a neonatal hematopoietic system dominated by fetal hemoglobin (HbF), shifting the oxygen‐dissociation curve and increasing oxygen delivery to immature tissues.
