Activating inert non-defect sites in Bi catalysts using tensile strain engineering for highly active CO electroreduction.

Bi-defect sites are highly effective for CO reduction (CORR) to formic acid, yet most catalytic surfaces predominantly feature inert, non-defective Bi sites. To overcome this limitation, herein, tensile strain is introduced on wholescale non-defective Bi sites. Under rapid thermal shock, the Bi-based metal-organic framework (Bi-MOF-TS) shows weakened Bi-O bonds and produced tiny Bi clusters.

Noise-immune zeroing neural dynamics for dynamic signal source localization system and robotic applications in the presence of noise.

Time angle of arrival (AoA) and time difference of arrival (TDOA) are two widely used methods for solving dynamic signal source localization (DSSL) problems, where the position of a moving target is determined by measuring the angle and time difference of the signal's arrival, respectively. In robotic manipulator applications, accurate and real-time joint information is crucial for tasks such as trajectory tracking and visual servoing. However, signal propagation and acquisition are susceptible to noise interference, which poses challenges for real-time systems.

However, radiotherapy has numerous side effects because it kills tumors while causing damage to normal cells or tissues. The literature shows that radiation can cause damage to heart tissue.

Research on cutting mechanism and process optimization method of gear skiving.

The cutting force and cutting temperature have a significant impact on the service life and durability of gear skiving cutters. Due to unreasonable design, the existing process parameters lead to dramatically nonuniform cutting force and cutting temperature, which aggravates the rapid wear of gear skiving cutters. To address this issue, this paper first establishes a finite element model of skiving the internal circular arc tooth in pin wheel housing, and the simulation model is simplified to improve computation efficiency.

LMNA-related cardiomyopathy: From molecular pathology to cardiac gene therapy.

Background: The genetic variants of LMNA cause an array of diseases that often affect the heart. LMNA-related cardiomyopathy exhibits high-penetrance and early-onset phenotypes that lead to late-stage heart failure or lethal arrhythmia. As a subtype of dilated cardiomyopathy and arrhythmogenic cardiomyopathy, LMNA-related cardiac dysfunction is resistant to existing cardiac therapeutic strategies, leaving a major unmet clinical need in cardiomyopathy management.

Polyvinyl alcohol/chitosan hydrogel based on deep eutectic solvent for promoting methicillin-resistant Staphylococcus aureus-infected wound healing.

Pralatrexate represses the resistance of HCC cells to molecular targeted agents via the miRNA-34a/Notch pathway.

Metabolism-related pathways are important targets for intervention in the treatment of hepatocellular carcinoma (HCC), but few studies have reported on the combination of inhibitors of folate metabolism-related enzymes and molecularly targeted drugs for HCC. The results of the present work are the first to reveal the effects of an inhibitor of dihydrofolate reductase (DHFR), pralatrexate, on the sensitivity of HCC cells to molecularly targeted agents examined using multiple assays. In HCC cells, knockdown of DHFR or treatment with pralatrexate enhanced the sensitivity of HCC cells to molecularly targeted agents, such as sorafenib, regorafenib, lenvatinib, cabozantinib, or anlotinib.

Propionate-producing engineered probiotics ameliorated murine ulcerative colitis by restoring anti-inflammatory macrophage via the GPR43/HDAC1/IL-10 axis.

Inflammatory bowel disease (IBD) is a chronic and unspecific inflammatory disorder of the gastrointestinal tract, and current treatment options often fail to maintain long-term remission. Studies have shown that propionate level is reduced in fecal samples from patients with IBD. Propionate can ameliorate IBD through intestinal epithelial cells and immune regulation, but its effects on the inflammatory microenvironment and macrophage differentiation have not been widely studied.

Palladium catalyzed ortho-C(sp)-H activation/cyclization of aryl amines assisted by imine and vinylacetic acid.

Palladium-catalyzed directed C - H functionalization/cyclization is an effective approach for synthesizing nitrogen heterocycles. Imine, known for its ease of installation/removal, has been extensively used in the C-H activation of aldehydes, ketones, and alkylamines. Nevertheless, it has been rarely explored in the C(sp)-H activation of aryl amines because of the generation of a strained four-membered palladacycle.
