Catalytic acceptorless complete dehydrogenation of cycloalkanes.

The advancement of an effective hydrogen liberation technology from liquid organic hydrogen carriers, particularly cycloalkanes such as cyclohexane and methylcyclohexane, holds significance in realizing a hydrogen-centric society. However, the attainment of homogeneous catalytic acceptorless dehydrogenation characterized by elevated selectivity for thorough aromatization under mild conditions remains unrealized. In this study, a catalyst system, facilitated by a double hydrogen atom transfer processes, has been devised for the catalytic acceptorless dehydrogenation of inert cycloalkanes at ambient temperature under visible light irradiation.

Persistence of newly prescribed 5-aminosalicylic acid in patients with ulcerative colitis: A nationwide comprehensive database study.

The 5-aminosalicylic acid (5-ASA) agents are first-line drugs for ulcerative colitis (UC). However, intolerance as well as other issues have been reported for these drugs, making it difficult to sustain this treatment; accordingly, the persistence of 5-ASA is an important indicator of UC treatment strategy. We aimed to analyze the persistence of 5-ASA in patients with UC in Japan.

Effects of nintedanib on circulating biomarkers of idiopathic pulmonary fibrosis.

Background: Biomarkers that change in response to nintedanib in subjects with idiopathic pulmonary fibrosis (IPF) would be valuable. We investigated the effects of nintedanib on circulating biomarkers in subjects with IPF in the INMARK trial.

Methods: Subjects with IPF were randomised 1:2 to receive nintedanib 150 mg twice daily or placebo for 12 weeks, after which all patients received open-label nintedanib for 40 weeks.

Hypoxia-inducible factor-targeting therapy augmented the sensitivity to programmed death ligand-1 blockade by enhancing interferon-γ-induced chemokines in tumor cells.

Immune checkpoint inhibitors (ICIs) targeting programmed death ligand-1 (PD-L1) provide clinical benefits for various advanced malignancies. However, the predictive factors that determine sensitivity to ICIs have not been fully elucidated. We focused on tumor-derived CXCL10/11 as a pivotal factor that determines the response to PD-L1 blockade by regulating T cell accumulation and tumor angiogenesis.

Original articles: step-by-step decision-making for achieving oncologically acceptable but avoiding over-invasive surgery for gallbladder cancer.

Background: Gallbladder cancer is a malignancy with a highly dismal prognosis, requiring optimal surgical strategies to achieve effective outcomes. We aimed to evaluate the outcomes of our algorithm-based decision-making approach based on image T-factors and intraoperative pathology of regional lymph node metastases and the bile duct stumps in patients undergoing gallbladder cancer resection.

Methods: A prospectively maintained database of patients who underwent gallbladder cancer resection between April 2001 and June 2022 was reviewed.
