Background: Inflammatory bowel disease (IBD) is one of the fastest-growing diseases globally. Nearly 5 million people are affected by IBD, with an incremental growth rate of 47.45% between 1990 and 2019.
Aim And Methods: We aim to provide a noninvasive approach to detecting IBD with an in-house developed 1310 nm endoscopic optical coherence tomography (OCT) system. Mice with acute colitis underwent a longitudinal colon imaging process for real-time and long-run disease progression. The OCT images were processed and segmented using a computer vision image processing-based segmentation algorithm for further thickness mapping and attenuation coefficient calculations.
Result: An increase in overall colon wall thickness due to inflammation was observed, as well as a reduction in attenuation coefficient due to a change in refractive index.
Conclusion: Comparable results with white light endoscope and histological examination suggest the clinical potential of the 1310 nm endoscopic OCT system for in vivo assessment of IBD.

Macrophage metabolic reprogramming refers to the process by which macrophages adjust their physiological pathways to meet survival and functional demands in different immune microenvironments. This involves a range of metabolic pathways, including glycolysis, the tricarboxylic acid cycle, oxidative phosphorylation, fatty acid oxidation, and cholesterol transport. By modulating the expression and activity of key enzymes and molecules within these pathways, macrophages can make the transition between pro- and anti-inflammatory phenotypes, thereby linking metabolic reprogramming to inflammatory responses and the progression of several diseases, such as atherosclerosis, inflammatory bowel disease (IBD), and acute lung injury (ALI).

Exocrine pancreatic insufficiency (EPI) is a major cause of maldigestion and malnutrition, resulting from primary pancreatic diseases or other conditions. As the prevalence of EPI continues to rise, accurate identification of its etiology has become critical for the diagnosis and treatment of pancreatic secretory insufficiency. EPI can result from both pancreatic and non-pancreatic disorders.

Background: Ulcerative colitis (UC), a typical inflammatory bowel disease (IBD), is pathologically defined by mucosal inflammation confined to the colonic mucosa. (Sb), a commonly utilized probiotic yeast for managing digestive disorders like UC, has not been thoroughly investigated regarding its precise mechanisms for alleviating colitis. Increasing evidence indicates the involvement of FXR in UC.
