NMR spectroscopy was used to measure reduction potentials of four redox proteins by following multiple (15)N HSQC protein resonances across a titration series using mixtures of oxidised and reduced glutathione. Results for PDI a, PDI ab and DsbA agree with the literature and our result for ERp18 confirms this protein as an oxidoreductase of comparable or greater reducing strength than PDI a.

Technetium-99m plays a pivotal role in nuclear medicine, offering unique IMAGING capabilities due to its favorable physical and chemical properties. This study investigates the redox behavior and electronic structures of three representative Tc(V) oxo complexes, [TcO(HMPAO)], [TcO(Bicisate)], and [TcO(DMSA)], using computational techniques. Employing relativistic density functional theory with the Zero-Order Regular Approximation (ZORA), we analyze singlet-triplet energy gaps, Gibbs free energy changes, and redox potentials in neutral and acidic environments.

Objective: To evaluate the feasibility, safety, and efficacy of microwave ablation (MWA) for the treatment of patients with Bethesda IV follicular neoplasms (FNs) (≤3 cm).

Methods: In the retrospective study, patients who underwent MWA for Bethesda IV follicular neoplasms (≤3 cm) were included. Technical success, volume reduction, disease progression, and adverse event (AE) rates were analyzed postablation.

Objectives: To evaluate the efficacy and safety of first-line targeted synthetic disease-modifying anti-rheumatic drugs (tsDMARDs) in patients with rheumatoid arthritis (RA) and chronic kidney disease (CKD).

Methods: This retrospective cohort study included 216 patients with RA prescribed their first tsDMARDs at two hospitals between 2013 and 2022. Dose reduction and contraindication guidelines for tsDMARDs according to kidney function were followed.

Preschool-onset major depressive disorder (PO-MDD) is an impairing pediatric mental health disorder that impacts children as young as three years old. There is limited work dedicated to uncovering neural measures of this early childhood disorder which could be leveraged to further understand both treatment responsiveness and future depression risk. Event-related potentials (ERPs) such as the P300 have been employed extensively in adult populations to examine depression-related deficits in cognitive and motivational systems.

Objectives: Caffeine, a known neurostimulant and adenosine antagonist, affects brain physiology by decreasing cerebral blood flow. It interacts with adenosine receptors to induce vasoconstriction, potentially disrupting brain homeostasis. However, the impact of caffeine on blood-brain barrier (BBB) permeability to water remains underexplored.
