Metabolic reprogramming shapes tumor microenvironment (TME) and may lead to immunotherapy resistance in pancreatic ductal adenocarcinoma (PDAC). Elucidating the impact of cancer cell metabolism TME is essential therapeutic interventions. "Immune cold" PDAC characterized by elevated lactate levels resulting from metabolism, abundance pro-tumor macrophages, reduced cytotoxic T TME. Analysis 18F-FDG uptake patients showed that increased global protein lactylation correlates with worse clinical...

Rare lipoprotein A (RlpA) is a widely conserved outer membrane protein of unknown function that has previously only been studied in Escherichia coli, where it localizes to the septal ring and scattered foci along lateral wall, but mutants have no phenotypic change. Here we show rlpA Pseudomonas aeruginosa form chains short, fat cells when grown low osmotic strength media. These morphological defects indicate RlpA needed for efficient separation daughter maintenance rod shape. Analysis...

Glioma incidence in the US seems to have stabilized over past 20 years. It's also not clear whether changes glioblastoma are associated with glioma mortality trends. Our study investigated trends and according tumor characteristics.This obtained data from Surveillance, Epidemiology, End Results-9 (SEER-9) registries calculate Annual percent (APC) 95% CIs were calculated using Joinpoint program.62,159 patients (34,996 males 55,424 whites) diagnosed during 1975-2018, 31,922 deaths occurred...

Eosinophils are granulocytes that play an essential role in type 2 immunity and regulate multiple homeostatic processes the small intestine (SI). However, signals eosinophil activity SI at steady state remain poorly understood. Through transcriptome profiling of eosinophils from various mouse tissues, we found a subset expressed neuromedin U (NMU) receptor 1 (NMUR1). Fate-mapping analyses showed NMUR1 expression was programmed by local microenvironment further enhanced inflammation. Genetic...

Abstract Stroke is a leading cause of death, with continuously increasing incidence. As metabolic process that catabolizes glucose pyruvate and provides adenosine triphosphate (ATP), glycolysis plays crucial role in different diseases. Phosphoglycerate kinase 1 (PGK1) facilitates energy production biosynthesis many diseases, including stroke. However, the exact PGK1/glycolysis stroke remains to be elucidated. A rat model middle cerebral artery occlusion (MCAO) was used mimic...

OBJECTIVE We aimed to evaluate whether individuals with type 2 diabetes (T2D) were at higher risk of developing a wide range gastrointestinal diseases based on population-based cohort study. RESEARCH DESIGN AND METHODS This study included 374,125 participants free disorders baseline; them, 19,719 (5.27%) T2D followed-up by linking multiple medical records record disease diagnoses. Multivariable Cox models used estimate the hazard ratios (HRs) and CIs. Logistic examine associations between...

ABSTRACT Crohn's disease (CD) is a prevalent type of inflammatory bowel (IBD) with dysregulated antibody responses. However, there lack comprehensive analysis B cell responses in CD. Here, we collected cells from the small intestine, colon and blood CD patients control subjects. Through coupled transcriptome immunoglobulin (Ig) gene individual cells, characterized cellular composition, Ig clonotype different subtypes. We observed shared disruptions plasma (PC) between IBD revealed...

Introduction: Gastroesophageal reflux disease (GERD) is a prevalent chronic condition primarily treated with proton pump inhibitors (PPIs). However, patients PPI-refractory GERD and hiatal hernia present significant therapeutic challenges, conventional treatments often yielding unsatisfactory outcomes. While anti-reflux mucosectomy (ARMS) has emerged as promising treatment, its efficacy in cases remains understudied. The primary objective of this case report to evaluate the safety ARMS...
