Achieving Photocatalytic Overall Nitrogen Fixation via an Enzymatic Pathway on a Distorted CoP Configuration.

Photocatalytic nitrogen (N) fixation over semiconductors has always suffered from poor conversion efficiency owing to weak N adsorption and the difficulty of N≡N triple bond dissociation. Herein, a Co single-atom catalyst (SAC) model with a C-defect-evoked CoP distorted configuration was fabricated using a selective phosphidation strategy, wherein P-doping and C defects co-regulate the local electronic structure of Co sites. Comprehensive experiments and theoretical calculations revealed that the distorted CoP configuration caused a strong charge redistribution between the Co atoms and adjacent C atoms, minimizing their electronegativity difference.

Screening and preparation of highly active antioxidant peptides of apricot and their inhibitory effect on ultraviolet radiation.

In today's social environment, the objective reality of people's increasing life pressure, environmental deterioration, and enhanced ultraviolet rays caused by the destruction of the ozone layer has led to the aggravation of people's oxidative stress. Therefore, exogenous antioxidant peptides have become a hot topic in research. In the context of insufficient protein supply and resource recycling, almond meal was used as raw material in this study.

Tao-Hong-Si-Wu-Tang improves thioacetamide-induced liver fibrosis by reversing ACSL4-mediated lipid accumulation and promoting mitophagy.

Ethnopharmacological Relevance: Liver fibrosis is a generic fibrous scarring event resulting from accumulation of extracellular matrix (ECM) proteins, easily progressing to end-stage liver diseases. Tao-Hong-Si-Wu-Tang (THSWT) is a traditional Chinese medicine formula applied in clinics to treat gynecological and chronic liver diseases. However, the role of THSWT on thioacetamide (TAA)-induced hepatic fibrosis and the specific mechanisms remains unclear.

SGK1 aggravates idiopathic pulmonary fibrosis by triggering H3k27ac-mediated macrophage reprogramming and disturbing immune homeostasis.

Idiopathic pulmonary fibrosis (IPF) is characterized by fibrotic matrix deposition and irreversible aberrant tissue remodeling. Their mechanisms of action are associated with the activation of macrophages and a disturbed immune environment. We aim to determine how these activated macrophages influenced the pathogenesis of pulmonary fibrosis.

FBXO28 suppresses liver cancer invasion and metastasis by promoting PKA-dependent SNAI2 degradation.

FBXO28 is a member of F-box proteins that are the substrate receptors of SCF (SKP1, CULLIN1, F-box protein) ubiquitin ligase complexes. Despite the implications of its role in cancer, the function of FBXO28 in epithelial-mesenchymal transition (EMT) process and metastasis for cancer remains largely unknown. Here, we report that FBXO28 is a critical negative regulator of migration, invasion and metastasis in human hepatocellular carcinoma (HCC) in vitro and in vivo.

Liver retraction using n-butyl-2-cyanoacrylate glue during laparoscopic cholecystectomy.

There might be a thick "protrusion" in the visceral surface of hepatic quadrate lobe during the laparoscopic cholecystectomy (LC), which affects the surgical fields and consequently triggers high risks of biliary tract injury. Although n-butyl-2-cyanoacrylate (NBCA) glue has been applied to laparoscopic upper abdominal surgery for liver retraction, there is still no consensus on its safety and feasibility in LC. In this study, we investigated the safety, feasibility, and effectiveness of liver retraction using NBCA glue for these patients which have the thick "protrusion" on the square leaf surface of the liver during LC.

Rational Design of Crystallization-Induced-Emission Probes To Detect Amorphous Protein Aggregation in Live Cells.

Unlike amyloid aggregates, amorphous protein aggregates with no defined structures have been challenging to target and detect in a complex cellular milieu. In this study, we rationally designed sensors of amorphous protein aggregation from aggregation-induced-emission probes (AIEgens). Utilizing dicyanoisophorone as a model AIEgen scaffold, we first sensitized the fluorescence of AIEgens to a nonpolar and viscous environment mimicking the interior of amorphous aggregated proteins.
