Background: The combination of regorafenib and immune checkpoint inhibitor (ICI) has been the most popular second-line systemic therapy for advanced hepatocellular carcinoma (HCC). However, considering the good anti-tumor performance of lenvatinib, combined immunotherapy on the basis of lenvatinib after first-line lenvatinib failure is also popular in clinical practice. This study aimed to compare the efficacy and safety of regorafenib plus ICI (TACE-R-I) versus lenvatinib plus ICI (TACE-L-I) in patients with advanced HCC after lenvatinib failure.

Gastric cancer (GC) is a huge threat to global health, there is no effective treatment or just delay the progression of advanced GC until now. Micro-RNAs were reported to participate in the progression of GC. Clonal formation, MTT, caspase-3 activity, sperm DNA fragmentation, flow cytometry assay, cell adhesion, transwell assays were performed to detect the functions of miR-32-5p or anti-miR-32-5p on the growth and metastasis of GC cells.

In this study, we present a novel catalyst-free energy transfer mediated radical rearrangement strategy for the aryl-heterofunctionalization of unactivated alkynes, leading to the synthesis of polyfunctional olefins with exceptional stereoselectivity. This innovative approach, driven by visible light, exemplifies green chemistry principles by eliminating the reliance on transition metals, external oxidants, and photocatalysts. The broad applicability of our method is demonstrated through the successful synthesis of a diverse array of compounds, including vinyl sulfones, vinyl selenides, and vinyl sulfides.

Parkinson's disease (PD) is a neurodegenerative disorder, and the main clinical characteristics are bradykinesia and muscle stiffness. Cognitive impairment (CI) is a prevalent non-motor manifestation observed in individuals with PD. According to disease severity, it can be divided into PD with mild cognitive impairment (MCI) and PD dementia.

Electrochemical nitrate reduction reaction offers a sustainable and efficient pathway for ammonia synthesis. Maintaining satisfactory Faradaic efficiency for long-term nitrate reduction under ampere-level current density remains challenging due to the inevitable hydrogen evolution, particularly in pure nitrate solutions. Herein, we present the application of electron deficiency of Ru metals to boost the repelling effect of counter K ions via the electric-field-dependent synergy of interfacial water and cations, and thus largely promote nitrate reduction reaction with a high yield and well-maintained Faradaic efficiency under ampere-level current density.

Objective: The authors report on a broad range of microsurgical procedures in which the suboccipital median technique was used to treat craniocervical junction arteriovenous fistulas. Their aim was to evaluate the efficacy of the suboccipital posteromedian approach and to assess the associated clinical outcomes.

Methods: The authors extracted information on the fistula site, clinical manifestation, and structural characteristics of arterial and venous vessels by retrospectively evaluating cases from a neurointerventional database spanning 10 years.

Article Synopsis
  • The study aimed to find a biomarker to predict how effectively patients with hepatocellular carcinoma (HCC) respond to transarterial chemoembolization (TACE), analyzing genetic and imaging data.
  • Using data from multiple sources, the researchers developed a TACE failure signature (TFS) based on specific genes and radiomics features, which indicated poorer survival rates for patients with higher TFS scores.
  • The findings suggest that the TFS correlates with both imaging characteristics and immune microenvironment factors, indicating broader implications for predicting responses to immunotherapy in these patients.

Background/objective: The pathogenesis and vascular remodeling during pulmonary hypertension (PH) have been associated with dysregulation of bone morphogenetic protein receptor type 2 (BMPR2) and transforming growth factor-β (TGF-β) signaling in pulmonary artery smooth muscle cells (PASMCs). Evidence suggests that the human-specific lncRNA MYOSLID is a transcriptional target of the TGF-β/SMAD pathway. In this study, we investigated the involvement of MYOSLID in the pathogenesis of PH.

Nonoxidative dehydrogenation of propane is useful for the high selectivity to propylene but is suffering from the heavy coke deposition on the catalyst surface. Herein, we present a proof-of-concept application of a hole-hydrogen (H) couple on a metallic cobalt surface to decrease the deactivation rate. The coupled H atoms on the Cobalt (Co) surface, partially resulting from propane dehydrogenation, enabled the desorption of propylene to avoid deep hydrogenolysis and coke deposition and realize selective and durable propylene production, while conventional Co metal-based catalysts do not generate propylene.

  • The study investigates the effects of traditional foam rolling versus vibration foam rolling on muscle metabolism and microvascular function in physically active young males.
  • Fifteen participants were tested, measuring muscle response using various spectroscopic techniques before and after both foam rolling methods.
  • Results showed that while foam rolling can reduce muscle metabolism and improve some microvascular function aspects, vibration foam rolling did not provide any extra benefits compared to regular foam rolling.
