Dysregulated serotonin/5-hydroxytryptamine (5-HT) metabolism and dense mucosal neurite distribution are associated with visceral hypersensitivity (VH), which plays a key role in irritable bowel syndrome (IBS) pain symptoms. The 5-HT receptor subtype 7 (5-HT) is involved in neuroplasticity. We aim to investigate the analgesic effects of 5-HT antagonists in mouse models and explore downstream changes of nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) in the enteric neurons.

Sulfatases mediate the sulfation level of cell-surface heparan sulfates to regulate signal transduction, thereby promoting cancer progression. Sulfatase activation requires a sulfatase modifying factor (SUMF) for the modification of its catalytic domain. The role of the SUMF family in urothelial carcinoma (UC) has not been adequately evaluated.

Background: Superior mesenteric ischemia/reperfusion (I/R) causes barrier dysfunction and facilitates bacterial translocation (BT) in the small intestine, which can even lead to systemic sepsis. Our previous research showed that luminal administration of glucose and its anaerobic glycolytic metabolites exerted cytoprotective effects on epithelial cells and ameliorated I/R-induced BT in the liver and spleen. Notably, the reduction of BT occurs over the whole intestinal tract, not only restricted in the ligated glucose-containing loop.

Introduction: Health records serve not only as a database of a patient's health history and treatment process but also as a crucial tool for doctors to diagnose and treat patients. However, the storage and sharing of these records are sensitive issues as they involve maintaining patient privacy and ensuring data transparency, security, and interoperability between different parties. Challenges to achieving these goals in the current surgical process can impact the allocation of medical resources and surgical outcomes.

The suppressive regulatory T cells (Treg) are frequently upregulated in cancer patients. This study aims to demonstrate the hypothesis that arecoline could induce the secretion of mitochondrial (mt) DNA D-loop and programmed cell death-ligand 1 (PD-L1) in extracellular vesicles (EVs), and attenuate T-cell immunity by upregulated Treg cell numbers. However, the immunosuppression could be reversed by whole glucan particle (WGP) β-glucan in oral squamous cell (OSCC) patients.

We experimentally realize a spin-momentum lattice with a homogeneously trapped Fermi gas. The lattice is created via cyclically rotated atom-laser couplings between three bare atomic spin states, and are such that they form a triangular lattice in a synthetic spin-momentum space. We demonstrate the lattice and explore its dynamics with spin- and momentum-resolved absorption imaging.

Epithelial cells are the first line of mucosal defense. In the intestine, a single layer of epithelial cells must establish a selectively permeable barrier that supports nutrient absorption and waste secretion while preventing the leakage of potentially harmful luminal materials. Key to this is the tight junction, which seals the paracellular space and prevents unrestricted leakage.

Objective: Intestinal barrier loss is a Crohn's disease (CD) risk factor. This may be related to increased expression and enzymatic activation of myosin light chain kinase 1 (MLCK1), which increases intestinal paracellular permeability and correlates with CD severity. Moreover, preclinical studies have shown that MLCK1 recruitment to cell junctions is required for tumour necrosis factor (TNF)-induced barrier loss as well as experimental inflammatory bowel disease progression.
