Mesoporous Boron-Doped Carbon with Curved BC Active Sites for Highly Efficient HO Electrosynthesis in Neutral Media and Air-Supplied Environments.

Hydrogen peroxide (HO) electrosynthesis via the 2e oxygen reduction reaction (ORR) is considered as a cost-effective and safe alternative to the energy-intensive anthraquinone process. However, in more practical environments, namely, the use of neutral media and air-fed cathode environments, slow ORR kinetics and insufficient oxygen supply pose significant challenges to efficient HO production at high current densities. In this work, mesoporous B-doped carbons with novel curved BC active sites, synthesized via a carbon dioxide (CO) reduction using a pore-former agent, to simultaneously achieve excellent 2e ORR activity and improved mass transfer properties are introduced.

Cavoatrial Bypass for Cardiac Complications From Rosai-Dorfman Disease.

DC. Regulates Vascular Smooth Muscle Cell Proliferation by Modulating -GlcNAc and MOF Expression.

Vascular smooth muscle cells (VSMCs) undergo metabolic pathway transitions, including aerobic glycolysis, fatty acid oxidation, and amino acid metabolism, which are important for their function. Metabolic dysfunction in VSMCs can lead to age-related vascular diseases. -GlcNAcylation, a nutrient-dependent posttranslational modification linked specifically to glucose metabolism, plays an important role in this context.

Magnolia kobus DC. suppresses neointimal hyperplasia by regulating ferroptosis and VSMC phenotypic switching in a carotid artery ligation mouse model.

However, vascular protective effects of MO remain incompletely understood. In this study, we evaluated the vascular protective effect of MO against ferroptosis in a carotid artery ligation (CAL)-induced neointimal hyperplasia mouse model and in aortic thoracic smooth muscle A7r5 cells.

Colorimetric Polydiacetylene Nanotubes from Self-Assembly of a Barbituric Acid-Derived Diacetylene.

Covalent organic nanotubes offer enhanced stability, robustness, and functionality, compared to their noncovalent counterparts. This study explores constructing polydiacetylene (PDA) nanotubes using a two-step process: self-assembly via noncovalent interactions followed by UV-induced polymerization of a diacetylene template. A promising building block consisting of a hydrogen-bonding headgroup, barbituric acid, linked to a linear diacetylene chain was prepared.

We aimed to evaluate bacterial contamination of autologous blood salvaged during DDLT and its association with post-transplant bacteremia.

Improved graft survival by using three-dimensional printing of intra-abdominal cavity to prevent large-for-size syndrome in liver transplantation.

Backgrounds/aims: While large-for-size syndrome is uncommon in liver transplantation (LT), it can result in fatal outcome. To prevent such fatality, we manufactured 3D-printed intra-abdominal cavity replicas to provide intuitive understanding of the sizes of the graft and the patient's abdomen in patients with small body size between July 2020 and February 2022.

Methods: Clinical outcomes were compared between patients using our 3D model during LT, and patients who underwent LT without 3D model by using 1 : 5 ratio propensity score-matched analysis.

Sulfur-doped silicon oxycarbide by facile pyrolysis process as an outstanding stable performance lithium-ion battery anode.

Silicon oxycarbide (SiOC) is drawing significant attention as a potential anode material for lithium-ion batteries due to its remarkable cycle life and the distinctive Si-O-C hybrid bonding within its structure. However, a notable drawback of SiOC-based electrodes is their poor electrical conductivity. In this study, we synthesized sulfur-doped silicon oxycarbide (S-SiOC) facile one-pot pyrolysis from a mixture of commercial silicone oil with 1-dodecanethiol.

Comparison of Clinical Outcomes Using Left and Right Liver Grafts in Adult-to-adult Living-donor Liver Transplantation: A Retrospective Cohort Study Using the Korean Organ Transplantation Registry.

Background: Living-donor liver transplantation has been widely performed as an alternative to the scarce liver grafts from deceased donors. More studies are reporting favorable outcomes of left liver graft (LLG). This study compared the clinical outcomes between living-donor liver transplantation using LLG and right liver graft (RLG) with similar graft-to-recipient body weight ratios.

Dual function of PHF16 in reinstating homeostasis of murine intestinal epithelium after crypt regeneration.

Intestinal stem cells (ISCs) are highly vulnerable to damage, being in a constant state of proliferation. Reserve stem cells repair the intestinal epithelium following damage-induced ablation of ISCs. Here, we report that the epigenetic regulator plant homology domain (PHD) finger protein 16 (PHF16) restores homeostasis of the intestinal epithelium after initial damage-induced repair.
