Unveiling the mystery of hepatic epithelioid angiomyolipoma: A unique case report with literature review.

Hepatic epithelioid angiomyolipoma is a rare mesenchymal liver tumor within the perivascular epithelioid cell tumor family, known for its uncertain malignancy and potential for aggressive behavior. Clinical presentation, laboratory findings, and imaging results lack specificity, making pathological examination critical for definitive diagnosis. This case report presents a 61-year-old male patient with a single tumor in the right liver lobe, measuring approximately 101 mm × 99 mm.

Comparing PD-L1 and PD-1 inhibitors plus bevacizumab combined with hepatic arterial interventional therapies in unresetable hepatocellular carcinoma: A single-center, real-world study.

With the rise of anti-vascular endothelial growth factor antibody and programmed cell death-ligand 1 (PD-L1) regimens, particularly bevacizumab and atezolizumab, as first-line treatments for advanced hepatocellular carcinoma (HCC), there is a need to explore PD-L1 and programmed cell death 1 inhibitors in combination therapies for unresectable HCC (uHCC). Integrating systemic therapies with locoregional approaches is also emerging as a potent strategy. This study compares the outcomes of atezolizumab (PD-L1 inhibitor) and sintilimab (programmed cell death 1 inhibitor) with bevacizumab or its biosimilar, combined with hepatic arterial interventional therapies (HAIT) in uHCC patients.

Engineering triple O-Ti-O vacancy associates for efficient water-activation catalysis.

Defect engineering can create various vacancy configurations in catalysts by finely tuning the local electronic and geometric structures of the active sites. However, achieving precise control and identification of these defects remains a significant challenge, and the origin of vacancy configurations in catalysts, especially clustered or associated ones, remains largely unknown. Herein, we successfully achieve the controllable fabrication and quantitative identification of triple O-Ti-O vacancy associate (VVV) in nanosized Ni-doped TiO.

Development of novel broad-spectrum amphipathic antimicrobial peptides against multidrug-resistant bacteria through a rational combination strategy.

Introduction: In recent years, cationic amphipathic antimicrobial peptides (AMPs) have shown great promise in combating antibiotic resistance on account of their distinctive membrane-disruptive mechanism. However, the clinical application of AMPs is restricted by their unsatisfactory stability and safety. Although attempts have been made to improve the stability and safety of AMPs, many of them are accompanied by a decline in their antimicrobial activity and bacterial selectivity.

Prognostic roles of hematological indicators in programmed cell death protein 1/programmed cell death ligand 1 inhibitors for small-cell lung cancer: a retrospective cohort study.

Background: Lung cancer is the main cause of cancer death in the world, with small-cell lung cancer (SCLC) accounting for about 10-15% of all lung cancers. Although programmed cell death protein 1 (PD-1)/programmed cell death ligand 1 (PD-L1) inhibitors represent a major breakthrough in SCLC treatment, only a minority of patients will benefit and there is still a lack of accurate biomarkers to guide clinical application. Inflammation plays a crucial role in tumorigenesis, tumor development, metastasis, and drug resistance, but there is limited research on the predictive value of these inflammatory indicators in SCLC.
