Inhibition of Angiopoietin-2 rescues sporadic brain arteriovenous malformations by reducing pericyte loss.

Brain arteriovenous malformations (bAVMs) are a major cause of hemorrhagic stroke in children and young adults. These lesions are thought to result from somatic KRAS/BRAF mutations in brain endothelial cells (bECs). In this study, we introduce a new bAVM model by inducing a brain endothelial-specific Braf mutation using the Slc1o1c1(BAC)-CreER driver line.

AI-based fingerprint index of visceral adipose tissue for the prediction of bowel damage in patients with Crohn's disease.

The fingerprint features of visceral adipose tissue (VAT) are intricately linked to bowel damage (BD) in patients with Crohn's disease (CD). We aimed to develop a VAT fingerprint index (VAT-FI) using radiomics and deep learning features extracted from computed tomography (CT) images of 1,135 CD patients across six hospitals (training cohort,  = 600; testing cohort,  = 535) for predicting BD, and to compare it with a subcutaneous adipose tissue (SAT)-FI. VAT-FI exhibited greater predictive accuracy than SAT-FI in both training (area under the receiver operating characteristic curve [AUC] = 0.

Evaluating the efficacy of the SENO decision framework in managing metastatic spinal disease: a comparative study.

Background Context: The management of metastatic spinal disease presents a complex challenge, with no universally accepted guidelines currently available. A new treatment approach, termed the "SENO" (Systemic Conditions, Effectiveness of Systemic Treatment, Neurology, and Oncology) decision framework, was developed, incorporating a 12-point grading system for epidural spinal cord compression.

Purpose: This study aims to assess the clinical efficacy of the SENO decision framework and compare its outcomes with those from traditional treatment frameworks.

[Association between plasma-glycosylated hemoglobin A/high-density lipoprotein cholesterol ratio and urinary albumin-creatinine ratio in Chinese adults].

To explore the relationship between glycosylated hemoglobin A/high-density lipoprotein cholesterol ratio (HbA/HDL-C) and urinary albumin-creatinine ratio (UACR) in Chinese adults. In this cross-sectional study, the clinical data of 43 820 community residents (age>40 years) from the Risk Evaluation of Cancers in Chinese Diabetic Individuals (REACTION study; March-December 2012) across eight centers (Liaoning, Guangdong, Shanghai, Gansu, Guangxi, Henan, Hubei, and Sichuan) in China were collected and analyzed. Participants were divided into three groups based on UACR levels:<10 mg/g, 10-30 mg/g, and >30 mg/g.

Interstitial Cells of Cajal Are Required for Different Intestinal Motility Responses Induced by Acupuncture.

Background: The movement of intestinal smooth muscle is regulated by the external autonomic nervous system (ANS) and its internal enteric nervous system (ENS). Previous studies have shown that acupuncture has a bidirectional regulating effect on intestinal motility through the sympathetic and vagal ANSs. ENS can independently regulate the sensory, secretory, and motor functions of the intestine.

CELF6 as an Oncogene in Colorectal Cancer: Targeting Stem-Cell-Like Properties Through Modulation of mRNA Stability.

Background: Emerging evidence indicates the essential role of cancer stem cells (CSCs) in the development and progression of various cancers, including colorectal cancer (CRC). CELF6, a member of the cytosine-uridine-guanine-binding protein (CUG-BP), Elav-like family (CELF), has been reported to be downregulated in CRC tissues. This study aims to elucidate the role and underlying mechanisms of CELF6 in CRC progression.

Multi-omics landscape of childhood simple obesity: novel insights into pathogenesis and biomarkers discovery.

Background: The increasing incidence of childhood obesity annually has led to a surge in physical and mental health risks, making it a significant global public health concern. This study aimed to discover novel biomarkers of childhood simple obesity through integrative multi-omics analysis, uncovering their potential connections and providing fresh research directions for the complex pathogenesis and treatment strategies.

Methods: Transcriptome, untargeted metabolome, and 16 S rDNA sequencing were conducted on subjects to examine transcripts, metabolites in blood, and gut microflora in stool.

Comparisons of efficacy and safety of 400 or 800 ml bacterial count fecal microbiota transplantation in the treatment of recurrent hepatic encephalopathy: a multicenter prospective randomized controlled trial in China.

Background: Hepatic encephalopathy (HE) represents a critical complications of end-stage liver disease, serving as an independent predictor of mortality among patients with cirrhosis. Despite effective treatment with rifaximin, some patients with HE still progress to recurrent episodes, posing a significant therapeutic challenge. Recurrent HE is defined as experiencing two or more episodes within a 6-month period.

Identification and Immunological Characterization of Annexin B8 and Annexin E1 from Spirometra Erinaceieuropaei Spargana.

Sparganosis is a parasitic zoonotic disease that poses a serious threat to public hygiene and human health. Annexin is a phospholipid-binding protein with calcium ion binding activity, serving various important functions, including interaction with the parasite and regulation of the host's immune response. In this study, two annexin (ANX) family genes, Spirometra erinaceieuropaei (S.

The updated prevalence and risk factors of dementia in old adults in China: A cross-sectional study.

Background: The continuously increasing aging population and life expectancy have led to an inconsistent and underestimated dementia prevalence in China. An updated epidemiologic study is urgently needed.

Objective: To update the prevalence rate and risk factors of dementia in China.

A Comprehensive Evaluation of the HPV Neutralizing Antibodies in Guangzhou, China: A Comparative Study on Various HPV Vaccines.

Background: The evaluation of HPV vaccine effectiveness is essential for informing public health strategies, yet there remains a gap in understanding humoral immune responses generated by different HPV vaccine formulations in regional populations. This study addresses this gap by evaluating the immunogenicity of the newly developed HPV vaccine Cecolin (Wantai), alongside various imported vaccines, including bivalent, quadrivalent, and nonavalent options available in China.

Methods: From March 2023 to June 2024, a total of 352 participants were enrolled, including 87 females aged 9-14 years who received two doses of the bivalent HPV vaccine (Cecolin), 215 females aged 15-45 years who were fully vaccinated with various HPV vaccines, and 50 non-recipients.

FOS B cells: Key mediators of immunotherapy resistance in diverse cancer types.

While immunotherapy has marked significant advances in cancer treatment, resistance remains a challenge. The complexity of the tumor microenvironment, particularly the role of B cell subpopulations, is a critical factor affecting treatment efficacy. In this study, we conducted analyses of single-cell RNA sequencing data from immunotherapy patients ( = 25) to explore the biomarker of immunotherapy resistance.

Circular RNA HIPK3 mediates epithelial-mesenchymal transition of retinal pigment epithelial cells by sponging multiple microRNAs.

Epithelial-mesenchymal transition (EMT) of retinal pigment epithelial (RPE) cells plays key roles in the pathogenesis of multiple vitreoretinal diseases, leading to profound and permanent vision loss. Circular RNAs (circRNAs) are widespread and functional endogenous RNAs that could regulate gene expression in eukaryotes. The functions of circRNAs in mediating EMT has been reported in several diseases.
