Impact of mandatory environmental information disclosure on the capital cost: Evidence from listed companies in China.

Mandatory environmental information disclosure is characterized by formal environmental regulation and that the content of the disclosure promotes public participation and oversight in the environmental field. This paper studies the impact of mandatory environmental information disclosure (EID) enforcement in China on corporate capital cost using a difference-in-difference model. The results indicate that mandatory EID increases debt capital cost, but has no significant impact on equity capital cost, which differs from mainstream research that suggest EID can reduce capital cost.

Ferroptosis in hepatocellular carcinoma: Mechanisms and therapeutic implications.

Ferroptosis is a novel form of oxidative cell death, in which highly expressed unsaturated fatty acids on the cell membrane are catalyzed by divalent iron or ester oxygenase to promote liposome peroxidation. This process reduces cellular antioxidant capacity, increases lipid reactive oxygen species, and leads to the accumulation of intracellular ferrous ions, which disrupts intracellular redox homeostasis and ultimately causes oxidative cell death. Studies have shown that ferroptosis induces an immune response that has a dual role in liver disease, ferroptosis also offers a promising strategy for precise cancer therapy.

Revealing 5-(3,5-difluorobenzyl)-1H-indazole as the active pharmacophore of ALK/ROS1 dual inhibitors through theoretical calculations and biological activity evaluations.

Anaplastic lymphoma kinase (ALK) and tyrosine protein kinase (ROS1) are recognized as driver genes in lung cancer, with dual inhibition of both targets offering a promising approach to enhance therapeutic outcomes in non-small cell lung cancer (NSCLC). Although numerous ALK/ROS1 inhibitors have received FDA approval, detailed research into the essential active structural motifs within these inhibitors remains limited. Addressing this gap, the current study employed computer-aided drug design (CADD) methodologies, incorporating bioisosteric and conformational similarity principles to design and synthesize 31 dual-target 2-morpholinobenzamide derivatives.

LRRK2 Gene Mutation Causes Skeletal Muscle Impairment in Animal Model of Parkinson's Disease.

Background: While the gradually aggravated motor and non-motor disorders of Parkinson's disease (PD) lead to progressive disability and frequent falling, skeletal muscle impairment may contribute to this condition. The leucine-rich repeat kinase2 (LRRK2) is a common disease-causing gene in PD. Little is known about its role in skeletal muscle impairment and its underlying mechanisms.

Fecal microbiota from patients with Parkinson's disease intensifies inflammation and neurodegeneration in A53T mice.

Aims: We evaluated the potential of Parkinson's disease (PD) fecal microbiota transplantation to initiate or exacerbate PD pathologies and investigated the underlying mechanisms.

Methods: We transplanted the fecal microbiota from PD patients into mice by oral gavage and assessed the motor and intestinal functions, as well as the inflammatory and pathological changes in the colon and brain. Furthermore, 16S rRNA gene sequencing combined with metabolomics analysis was conducted to assess the impacts of fecal delivery on the fecal microbiota and metabolism in recipient mice.

Xiaoke Bitong capsule alleviates inflammatory impairment via inhibition of the TNF signaling pathway to against diabetic peripheral neuropathy.

A versatile upconversion-based multimode lateral flow platform for rapid and ultrasensitive detection of microRNA towards health monitoring.

MicroRNAs are small single-stranded RNA molecules associated with gene expression and immune response, suggesting their potential as biomarkers for health monitoring. Herein, we designed a novel upconversion-based multimode lateral flow assay (LFA) system to detect microRNAs in body fluids by simultaneously producing three unique signals within a detection strip. The core-shell Au-DTNB@Ag nanoparticles act as both the Raman reporters and acceptors, quenching fluorescence from upconversion nanoparticles (UCNPs, NaYF: Yb, Er) via the Förster resonance energy transfer mechanism.

α-Synuclein reduces acetylserotonin O-methyltransferase mediated melatonin biosynthesis by microtubule-associated protein 1 light chain 3 beta-related degradation pathway.

Previous studies have demonstrated that α-synuclein (α-SYN) is closely associated with rapid eye movement sleep behavior disorder (RBD) related to several neurodegenerative disorders. However, the exact molecular mechanisms are still rarely investigated. In the present study, we found that in the α-SYN induced RBD-like behavior mouse model, the melatonin level in the plasma and pineal gland were significantly decreased.

Dual functionalized copper nanoparticles for thermoplastics with improved processing and mechanical properties and superior antibacterial performance.

The utilization of metal nanoparticles for antibacterial thermoplastic composites has the potential to enhance the safety of human and animal life by mitigating the spread and transmission of foodborne pathogenic bacteria. The dispersion, antioxidant and antimicrobial activities of metal nanoparticles directly affect the application performance of the composites. This study focused on achieving amine-carboxyl co-modified copper nanoparticles (Cu-AC) with excellent antioxidant properties and monodispersity through grafting of amine and carboxyl groups onto the surface of copper nanoparticles ligand interaction.

The role of Nurr1-miR-30e-5p-NLRP3 axis in inflammation-mediated neurodegeneration: insights from mouse models and patients' studies in Parkinson's disease.

Nuclear receptor related-1 (Nurr1), a ligand-activated transcription factor, is considered a potential susceptibility gene for Parkinson's disease (PD), and has been demonstrated to possess protective effects against inflammation-induced neuronal damage. Despite the evidence showing decreased NURR1 level and increased pro-inflammatory cytokines in cell and animal models as well as in PD patients' peripheral blood mononuclear cells (PBMCs), the underlying mechanism remains elusive. In this study, we investigated the molecular mechanism of Nurr1 in PD-related inflammation.

TaACTIN7-D regulates plant height and grain shape in bread wheat.

Exploitation of new gene resources and genetic networks contributing to the control of crop yield-related traits, such as plant height, grain size, and shape, may enable us to breed modern high-yielding wheat varieties through molecular methods. In this study, via ethylmethanesulfonate mutagenesis, we identify a wheat mutant plant, mu-597, that shows semi-dwarf plant architecture and round grain shape. Through bulked segregant RNA-seq and map-based cloning, the causal gene for the semi-dwarf phenotype of mu-597 is located.

Image Registration for Visualizing Magnetic Flux Leakage Testing under Different Orientations of Magnetization.

The Magnetic Flux Leakage (MFL) visualization technique is widely used in the surface defect inspection of ferromagnetic materials. However, the information of the images detected through the MFL method is incomplete when the defect (especially for the cracks) is complex, and some information would be lost when magnetized unidirectionally. Then, the multidirectional magnetization method is proposed to fuse the images detected under different magnetization orientations.

Ferroptosis and its role in skeletal muscle diseases.

Ferroptosis is characterized by the accumulation of iron and lipid peroxidation products, which regulates physiological and pathological processes in numerous organs and tissues. A growing body of research suggests that ferroptosis is a key causative factor in a variety of skeletal muscle diseases, including sarcopenia, rhabdomyolysis, rhabdomyosarcoma, and exhaustive exercise-induced fatigue. However, the relationship between ferroptosis and various skeletal muscle diseases has not been investigated systematically.
