A Biomimetic Norepinephrine‐Loaded Aligned Mineralized Collagen Scaffold for Coordinated Neurovascular, Osteogenic, and Immunomodulatory Repair of Critical‐Sized Bone Defects

Advanced Science, EarlyView.
Inspired by the composition and structure of native bone tissue and its complex interplay of biological signals, a norepinephrine‐loaded biomimetic mineralized electrocompacted collagen scaffold (NE‐MEC) is developed capable of simultaneously supporting osteogenesis, neural repair, angiogenesis, and immune modulation.

Intratumoral Fusobacterium nucleatum Drives Cancer‐Associated Fibroblasts Enrichment and Immune Exclusion in Esophageal Squamous Cell Carcinoma

Annals of Gastroenterological Surgery, EarlyView.
Fusobacterium nucleatum contributes to the progression of ESCC by inducing NF‐κB–mediated inflammatory signaling in tumor cells and promoting CAFs activation. Its presence may facilitate immune exclusion and tumor invasion through stromal remodeling. Furthermore, F.

Increased prevalence of precancerous changes in relatives of gastric cancer patients: critical role of H. pylori [PDF]

, 2000
Background & Aims:Helicobacter pylori is believed to predispose to gastric cancer by inducing gastric atrophy and hypochlorhydria. First-degree relatives of patients with gastric cancer have an increased risk of developing gastric cancer.

Toward Predictable Nanomedicine: Current Forecasting Frameworks for Nanoparticle–Biology Interactions

Advanced Intelligent Discovery, EarlyView.
Predictive models successfully screen nanoparticles for toxicity and cellular uptake. Yet, complex biological dynamics and sparse, nonstandardized data limit their accuracy. The field urgently needs integrated artificial intelligence/machine learning, systems biology, and open‐access data protocols to bridge the gap between materials science and safe ...

Radium Speciation in Simulated Digestive Biofluids: Insights from Electrospray Ionization Mass Spectrometry and Thermodynamic Modeling

Analysis &Sensing, EarlyView.
Electrospray ionization mass spectrometry (ESI‐MS) combined with thermodynamic modeling provides the first direct characterization of radium speciation in synthetic gastrointestinal biofluids. Free Ra2+ ions predominate with minimal protein binding and negligible EDTA complexation. Crown ethers enable effective Ra complexation.

Exploring the Roles of Tuna‐Associated Acinetobacter sp. YFT067: Implications for Host Health and Metabolism

Animal Research and One Health, EarlyView.
This study firstly isolated a tuna‐derived gut probiotic Acinetobacter seifertii YFT067. Dietary administration of YFT067 played significant roles in promoting growth performance, SCFAs production, lipid absorption, and metabolism of the host, indicating YFT067 as a promising probiotic candidate for enhancing tuna aquaculture productivity through ...

GastroNet: A robust attention‐based deep learning and cosine similarity feature selection framework for gastrointestinal disease classification from endoscopic images

CAAI Transactions on Intelligence Technology, EarlyView., 2023
Abstract Diseases of the Gastrointestinal (GI) tract significantly affect the quality of human life and have a high fatality rate. Accurate diagnosis of GI diseases plays a pivotal role in healthcare systems. However, processing large amounts of medical image data can be challenging for radiologists and other medical professionals, increasing the risk ...
