Abstract Intestinal fibrosis is a serious complication in inflammatory bowel disease (IBD). Despite the remarkable success of recent anti-inflammatory therapies for IBD, incidence intestinal and need resection have not significantly changed. To clarify contribution haematopoietic-derived cells fibrosis, we prepared bone marrow (BM) chimeric mice (chimeras), which were reconstituted with BM derived from enhanced green fluorescent protein (EGFP)-transgenic or CC chemokine receptor 2...

Unresectable malignant bile duct stricture (often caused by unresectable pancreatic cancer and cholangiocarcinoma) can be drained via insertion of self-expandable metal stents (SEMS) during endoscopic retrograde cholangiopancreatography (ERCP). Because recurrent biliary obstruction (RBO) complications following stent delay chemotherapy other treatments, a longer time to RBO (TRBO) is desirable. Although TRBO has been reported among patients who undergo with larger diameter SEMS, smaller...

Abstract Following injury, skeletal muscle regenerates but fatty tissue accumulation is seen in aged or muscular dystrophies. Fibro/adipogenic progenitors (FAPs) are key players these events; however, the effect of primary cilia on FAPs remains unclear. Here, it reported that genetic ablation trichoplein (TCHP), a ciliary regulator, induces elongation after which promotes regeneration while inhibiting adipogenesis. The defective adipogenic differentiation attributed to dysfunction...

Abstract The introduction of anti-inflammatory therapies has enabled substantial improvement disease activity in patients with inflammatory bowel diseases (IBD). However, IBD can lead to serious complications such as intestinal fibrosis and colorectal cancer. Therefore, novel reducing the development these are needed. Angiotensin II (Ang II) promotes tissue inflammation by stimulating production monocyte chemoattractant protein-1 (MCP-1) or proinflammatory cytokines. It plays a pivotal role...

Abstract Hereditary hemochromatosis (HH) is recognized as a progressive iron‐storage disorder, and leading to severe organ impairments, including liver cirrhosis. type 3 arises from mutations in the transferrin receptor 2 ( TFR2 ) gene. However, HH rare Asia, information regarding genetic associated phenotypes remains limited. Here, we reported case of Japanese patient with 3, novel homozygous mutation A 69‐year‐old woman presented our hospital hand joint pain was referred due impairment....

The survival rate of pancreatic ductal adenocarcinoma (PDAC) is very poor because early detection difficult. Extracellular vesicles (EVs) are released from cells associating with the cellular condition and circulated in blood. We aimed to identify EV proteins endoscopic ultrasound-fine needle aspiration (EUS-FNA) biopsy samples order develop novel biomarkers for PDAC.Extracellular were isolated EUS-FNA 40 PDAC patients six autoimmune pancreatitis (AIP) be used as a control. identified using...

Pancreatic ductal adenocarcinoma (PDAC) is a leading cause of cancer-related death worldwide. The accuracy PDAC diagnosis based on endoscopic ultrasonography-guided fine-needle aspiration cytology can be strengthened by performing rapid on-site evaluation (ROSE). However, ROSE only performed in limited number facilities, due to relative lack available resources or cytologists with sufficient training. Therefore, we developed the Mathematical Technology for Cytopathology (MTC) algorithm,...
