Significant research efforts have been devoted to improving the efficiency of catalytic carbon monoxide (CO) oxidation over α-FeO-based catalysts, but details of the underlying mechanism are still under debate. Here we apply the thermodynamic method (AITM) within the density functional theory framework to investigate the phase diagram of α-FeO(0001) surfaces with various terminations and the catalytic mechanism of CO oxidation on these surfaces. By extending the conventional AITM to consider the charge state of surface defects, we build the phase diagram of α-FeO(0001) surfaces in relation to the Fermi energy as well as the oxygen chemical potential, which makes it possible to explain the influence of point defects on the surface morphology and to predict the existence of the experimentally observed functional sites such as the ferryl group (FeO) and oxygen vacancies.

A randomized, partially blinded, placebo-controlled, crossover study in 48 healthy adults assessed the effect of momelotinib on the heart rate-corrected QT interval (QTc) using the Fridericia formula (QTcF). QTc was evaluated for momelotinib 200 mg (therapeutic dose), momelotinib 800 mg (supratherapeutic dose), moxifloxacin 400 mg (positive control), and placebo. Pharmacokinetic profiles of momelotinib and its active metabolite M21 were evaluated.

Background: Increasing evidence suggests that insomnia plays an important role in the development of depression, supporting insomnia intervention as a promising approach to prevent depression in youth. This randomized controlled trial evaluated the effectiveness of app-based cognitive behavioral therapy for insomnia (CBT-I) in preventing future onset of major depressive disorder (MDD) in youth.

Methods And Findings: This was a randomized, assessor-blind, parallel group-controlled trial in Chinese youth (aged 15-25 years) with insomnia disorder and subclinical depressive symptoms.

Background: Nurses on the frontlines of the pandemic have increased workloads, burnout, and virus exposure, leading to mental health challenges and a lack of resources for patient care. Mental health support for nurses during the COVID-19 outbreak has become a priority. This study evaluated psychological health outcomes of among nurses during the 2022-2023 COVID-19 pandemic in Taiwan, focusing on personal and work-related fatigue as key contributors to emotional distress.

Although breast cancer treatment has evolved significantly in recent years, drug resistance remains a major challenge. To identify new targets for breast cancer, we found that stage-specific embryonic antigen 4 (SSEA-4) is expressed in all subtypes of breast cancer cell lines, and the increased expression of the associated enzymes β3GalT5 and ST3Gal2 correlates with poor recurrence-free survival (RFS) in breast cancer. We also found that SSEA-4 antibodies can be rapidly internalized into breast cancer cells, a property that makes SSEA-4 an attractive target for antibody-drug conjugates (ADCs).
