Radical-radical reaction channels are important in the pyrolysis and oxidation chemistry of perfluoroalkyl substances (PFAS). In particular, unimolecular dissociation reactions within unbranched -perfluoroalkyl chains, and their corresponding reverse barrierless association reactions, are expected to be significant contributors to the gas-phase thermal decomposition of families of species such as perfluorinated carboxylic acids and perfluorinated sulfonic acids. Unfortunately, experimental data for these reactions are scarce and uncertain.

Genetic biofortification represents a highly useful solution to this problem.

Introduction: To evaluate the effectiveness of paracetamol and ibuprofen as non-opioid treatments for postpartum pain control after vaginal delivery.
Materials And Methods: This randomized controlled study at a university-affiliated medical center involved parturient who received blindly oral tablets of either 1000 mg of paracetamol or 400 mg of ibuprofen, post-vaginal birth. Pain levels were assessed using a numeric rating scale (NRS) at four time points: before treatment, and 1, 4, and 6 h post-treatment (T0, T1, T4, and T6, respectively).

Objective: To identify the key risk factors contributing to re-hospitalization after term cesarean delivery (CD).
Methods: This retrospective cohort study included women who underwent CD at term at a university-affiliated tertiary medical center (January 2021 to March 2023). The primary outcome was risk factors for re-hospitalization within 30 days post-discharge.
