Primary cutaneous rhabdomyosarcoma with EWSR1/FUS::TFCP2 fusion: four new cases with distinctive morphology, immunophenotypic, and genetic profile.

EWSR1/FUS::TFCP2-rearranged rhabdomyosarcoma (RMS) is a rare tumor with an aggressive clinical course, a predilection for craniofacial bones, spindled and/or epithelioid histomorphology, and positive immunohistochemistry (IHC) for epithelial and myogenic markers, along with variable ALK expression. Herein, we present four additional cases of primary cutaneous TFCP2-rearranged RMS. Notably, one tumor (case 1) displayed a varied pathological spectrum, initially presenting as a low-grade spindle cell neoplasm, but progressed into a high-grade spindle/epithelioid tumor.

Methoprene-Tolerant (Met) Acts as Methyl Farnesoate Receptor to Regulate Larva Metamorphosis in Mud Crab, .

The conserved role of juvenile hormone (JH) signals in preventing larvae from precocious metamorphosis has been confirmed in insects. Crustaceans have different metamorphosis types from insects; we previously proved that methyl farnesoate (MF) can prohibit larvae metamorphosis in mud crabs, but the molecular signal of this process still needs to be elucidated. In this study, () of was obtained and characterized, which we named .

Correlations between 14-gene RNA-level assay and clinical and molecular features in resectable non-squamous non-small cell lung cancer: a cross-sectional study.

Background: Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related death worldwide. Accurate risk stratification is essential for optimizing treatment strategies. A 14-gene RNA-level assay of lung cancer, which involves quantitative reverse transcription polymerase chain reaction (qRT-PCR) analysis of formalin-fixed paraffin-embedded (FFPE) tissue samples, offers a promising approach.

Analysis the Burden of Breast Cancer Among Adolescents and Young Adults Using the Global Burden of Disease 2021.

Patients And Methods: The data of incidence, deaths, and disability-adjusted life years (DALYs) owing to breast cancer was obtained from the Global Burden of Disease (GBD) 2021.

Dysregulation in keratinocytes drives systemic lupus erythematosus onset.

Systemic lupus erythematosus (SLE) is a complex, multiorgan autoimmune disorder. Although it is widely believed that SLE originates from immune cell dysregulation, the etiology of SLE is not yet clear. Here, we propose a new theory in which SLE can be directly initiated by molecular alterations in keratinocytes rather than immune cells.

Polypeptide-Folded Artificial Ferroprotein Promotes Ferroptosis in Multiple Tumor Cells.

Although the current nanozymes, such as FeO nanoparticles, exhibit biocatalytic activities, they dramatically differ from natural enzymes, lacking a degradable organic framework and an intrinsically flexible structure. Single-chain folding of a synthetic polypeptide by metal coordination can mimic metalloproteins more similarly. A triblock PEG-polypeptide copolymer, poly(ethylene glycol)--poly(but-3-yn-1-yl glutamate)--poly(-butyl glutamate) [EG(Glu-yne)(Glu-tBu)], was synthesized by NCA polymerization.

Ultrasound-Assisted Extraction of Alginate from Seaweed By-Product Post-Fucoidan Extraction.

The solid phase byproduct obtained after conventional fucoidan extraction from the brown seaweed can be used as a source containing alginate. This study involves ultrasound-assisted extraction (UAE) of alginate from the byproduct using sodium bicarbonate. Response surface methodology (RSM) was applied to obtain the optimum conditions for alginate extraction.

Causal associations of Helicobacter pylori infection and metabolic syndrome: insights from a two-sample Mendelian randomization study.

Background: Helicobacter pylori (Hp) infection and metabolic syndrome (MetS) have a high prevalence of co-morbidities and both pose a significant threat to human health and survival. It has been suggested that Hp infection affects the development of MetS in the host, but the causal relationship between the two has not been confirmed.

Methods: We conducted a two-sample Mendelian randomization study to investigate the causal effect of Hp infection with MetS and its components.

Anti-tumor activity and biomarker analysis for TROP2-antibody drug conjugate Datopotamab deruxtecan in patient-derived breast cancer xenograft models.

Background: Datopotamab deruxtecan (Dato-DXd), is a humanized anti-TROP2 IgG1 monoclonal antibody linked to a potent topoisomerase I inhibitor payload (DXd). Dato-DXd has already shown antitumor activity in breast cancer; however, the determinants of response, including the importance of TROP2 expression, remain unclear. We tested the activity of Dato-DXd in a panel of breast cancer patient-derived xenografts (BCXs) varying in TROP2 expression.

Association between advanced fibrosis and epigenetic age acceleration among individuals with MASLD.

Background: The biological process of aging plays an important role in the progress of liver fibrosis. However, epidemiological evidence about the associations between advanced fibrosis and epigenetic age acceleration (EAA) among individuals with metabolic dysfunction-associated steatotic liver disease (MASLD) is limited.

Methods: We utilized publicly available DNA methylation data (GSE180474) for our analysis.

Crystallographic Reorientation Induced by Gradient Solid-Electrolyte Interphase for Highly Stable Zinc Anode.

Oriented zinc (Zn) electrodeposition is critical for the long-term performance of aqueous Zn metal batteries. However, the intricate interfacial reactions between the Zn anode and electrolytes hinder a comprehensive understanding of Zn metal deposition. Here, the reaction pathways of Zn deposition and report the preferential formation of Zn single-crystalline nuclei followed by dense Zn(002) deposition is elucidated, which is induced by a gradient solid-electrolyte interphase (SEI).

A rationally designed CD19 monoclonal antibody-triptolide conjugate for the treatment of systemic lupus erythematosus.

Hook F (TWHF) is a traditional Chinese medicine widely used in the treatment of systemic lupus erythematosus (SLE), with triptolide (TP) as its main active ingredient. However, its side effects also induced by TP, especially hepatotoxicity and reproductive toxicity, largely limit its application in a subset of patients. Monoclonal antibodies (mAbs) developed for the treatment of SLE that deplete B cells by targeting B cell-expressing antigens, such as CD19, have failed in clinical trials, partly due to their poor efficacy in consuming B cells.

Enrichment, Antioxidant and Enzyme Inhibition Activities of Flavonoids from Artemisia Selengensis Turcz.

Macroporous resin was used to enrich flavonoids in the ethyl acetate extract of Artemisia Selengensis Turcz. Based on a single factor experiment, the enrichment process was optimized using the response surface method. The optimal parameters of the enrichment process were a sample concentration of 0.

IL-1β mediated fibroblast-neutrophil crosstalk promotes inflammatory environment in skin lesions of SLE.

Systemic lupus erythematosus (SLE) is characterized by immune dysregulation, with neutrophil infiltration in skin lesions contributing to inflammation and disease progression. However, the interaction between fibroblasts and neutrophils in SLE skin lesions has not been fully explored. Using single-cell RNA sequencing, we identified a unique CXCL1 fibroblast subset in SLE lesions.

Utilizing Patient-derived Xenografts to Model Precision Oncology for Biliary Tract Cancer.

Purpose: Biliary tract cancers (BTCs), which are rare and aggressive malignancies, are rich in clinically actionable molecular alterations.

Acriflavine-modified UIO-66 ratiometric fluorescent sensor for highly selective and fast detection of hypochlorite in water.

Hypochlorite (ClO) as a kind of highly toxic pollutant has garnered significant interest in detection methods, highlighting the pressing need to develop intelligent functional materials for the qualitative and quantitative analysis of ClO in aqueous solutions. Herein, a ratiometric fluorescent sensor was prepared by the combination of acriflavine (Acr) and UIO-66 via a post-synthetic modification strategy. Acr/UIO-66 exhibited both high crystallinity typical of metal-organic frameworks and demonstrated good fluorescent and thermal stability.

Comparative study on physicochemical characterization and immunomodulatory activities of neutral and acidic Lycium barbarum polysaccharides.

Lycium barbarum polysaccharides (LBPs) are recognized as key bioactive constituents of Lycium barbarum with diverse biological activities. However, current research on LBPs is largely confined to crude extracts, offering limited insight into the structural properties underlying their biological effects. In this study, we separated crude LBP into acidic LBP (ALBP) and neutral LBP (NLBP), which exhibited distinct physicochemical properties.
