Airway Basal Stem Cells Inflammatory Alterations in COVID‐19 and Mitigation by Mesenchymal Stem Cells

Cell Proliferation, EarlyView.
Airway basal stem cells derived from COVID‐19 patients demonstrated pronounced goblet cell hyperplasia, inflammatory responses and tendencies toward fibrosis. Co‐culture with mesenchymal stem cells (MSCs) notably reduced these pathological changes, likely due to MSCs' regulatory effects on the interferon signalling pathway.

Digestion Modelling in the Small Intestine : Impact of Dietary Fibre [PDF]

arXiv, 2012
In this work, we continue the modelling of the digestion in the small intestine, started in a previous article, by investigating the effects of dietary fibre. We recall that this model aims at taking into account the three main phenomena of the digestion, namely the transit of the bolus, the degradation of feedstuffs and the absorption through the ...

Diplostomum‐Induced Sac Formation in Lenses of Ameiurus Bullheads: A Host Defence Response?

Journal of Fish Diseases, EarlyView.
ABSTRACT Trematodes of the genus Diplostomum (Diplostomidae) are widely distributed and significant fish pathogens known for causing a range of negative effects. Any mechanism that protects the host from the parasite thus represents an evolutionary advantage.

The model of circular and longitudinal smooth muscle motions in the motility of intestinal segment [PDF]

arXiv, 2014
Coordination in circular and longitudinal muscle motions are of crucial importance in the motor function of gastrointestinal (GI) tract. Intestinal wall motions depend on myogenic-active properties of smooth muscles layers of intestinal wall, which is the ability to create active contractile forces in response to distension.

Application of Structural Similarity Analysis of Visually Salient Areas and Hierarchical Clustering in the Screening of Similar Wireless Capsule Endoscopic Images [PDF]

arXiv, 2020
Small intestinal capsule endoscopy is the mainstream method for inspecting small intestinal lesions,but a single small intestinal capsule endoscopy will produce 60,000 - 120,000 images, the majority of which are similar and have no diagnostic value. It takes 2 - 3 hours for doctors to identify lesions from these images.

The West Catching Up With the East: High‐Magnification NBI Is Accurate for the Diagnosis of Gastric Neoplasia in a Western Population

Journal of Gastroenterology and Hepatology, EarlyView.
ABSTRACT Background and Aim Accurate endoscopic prediction of histology is key to recognition of early gastric neoplasia and selection of appropriate resection techniques. Narrow‐band imaging with magnification (M‐NBI) has proven to be highly accurate for gastric lesions in eastern countries; however, we sought to examine whether it can be effectively ...

Increased Prevalence of Barrett's Esophagus in Taiwan: A Prospective Multicenter Study

Journal of Gastroenterology and Hepatology, EarlyView.
ABSTRACT Background and Aim With rising rates of esophageal adenocarcinoma (EAC) in Western countries, Barrett's esophagus (BE) has become a growing concern. The increasing prevalence of chronic gastroesophageal reflux disease (GERD) in Taiwan suggests a potential rise in BE cases as well.

Helicobacter pylori with stronger intensity of CagA phosphorylation lead to an increased risk of gastric intestinal metaplasia and cancer

BMC Microbiology, 2011
Background Nearly all Taiwanese H. pylori stains are cagA-genopositive and encode CagA protein. In this study, we evaluated whether different intensity of tyrosine phosphorylated-CagA (p-CagA) had an impact on the clinical diseases and histological ...

Osteohistology of the unusually fast‐growing theropod dinosaur Ceratosaurus

Journal of Anatomy, EarlyView.
We report the histology of multiple elements attributed to four individuals of Ceratosaurus. We find that the histology and growth models corroborate previous reports of rapid tissue growth in the genus. Abstract Ceratosaurus is a large‐bodied non‐avian theropod dinosaur known from the Upper Jurassic Morrison Formation of North America and is ...
