Small RNA Toxin‐Assisted Evolution of GC‐Preferred ErCas12a for Enhanced Genome Targeting Range

Advanced Science, EarlyView.
ErCas12a is engineered to target GC‐rich PAMs using a small RNA toxin‐aided positive screening system. The resulting variant, enErCas12a, exhibits an expanded PAM profile and facilitates efficient gene editing in both bacterial and mammalian cells, while preserving high targeting specificity for both canonical and non‐canonical PAM targets.

Smoking and nicotine in inflammatory bowel disease: good or bad for cytokines?

Mediators of Inflammation, 1998
Smoking has either a beneficial or harmful effect on the course and recurrence of ulcerative colitis and Crohn's disease respectively. Transdermal application of nicotine had similar effects in ulcerative colitis and therefore was considered to be an ...

ULCERATIVE COLITIS IN CHILDREN [PDF]

Romanian Journal of Pediatrics, 2009
Chronic nonspecific ulcerative colitis remaine a disease of unkown etiology, although much new information continues to be gleaned from basic research and clinical trials. In most instances, ulcerative colitis respond to medical therapy.

Gastrointestinal Mucosal Problems Classification with Deep Learning [PDF]

arXiv, 2023
Gastrointestinal mucosal changes can cause cancers after some years and early diagnosing them can be very useful to prevent cancers and early treatment. In this article, 8 classes of mucosal changes and anatomical landmarks including Polyps, Ulcerative Colitis, Esophagitis, Normal Z-Line, Normal Pylorus, Normal Cecum, Dyed Lifted Polyps, and Dyed ...

Differential expression of prolyl hydroxylase 1 in patients with ulcerative colitis versus patients with Crohn's disease/infectious colitis and healthy controls [PDF]

, 2013
Background: Inhibition of prolyl hydroxylases (PHDs) leads to the induction of a transcriptional program that, in the gut, promotes intestinal epithelial cell survival.

Engineered Tissue Models to Decode Host–Microbiota Interactions

Advanced Science, EarlyView.
Host–Microbiota interactions in the human body. Created in BioRender. Ghezzi, C. (2025) https://BioRender.com/ihivskg. Abstract A mutualistic co‐evolution exists between the host and its associated microbiota in the human body. Bacteria establish ecological niches in various tissues of the body, locally influencing their physiology and functions, but ...

CMV in the gut: a critical review of CMV detection in the immunocompetent host with colitis. [PDF]

, 2015
As scientific techniques for the detection of cytomegalovirus (CMV) improve, we are able to detect small amounts of CMV in the mucosal wall. As clinicians, we are unsure how to interpret the results of this novel test.

Magnetite Micro/Nanorobots for Efficient Targeted Alleviation of Inflammatory Bowel Disease

Advanced Science, EarlyView.
Improved reactive oxygen species scavenging capacities of functionalized micro/nanorobots (MNRs) are useful for the treatment of inflammatory bowel disease (IBD). MNRs can break the harmful bacteria in IBD, thereby eliminating inflammation and restoring the intestinal barrier function.

Soluble human Suppression of Tumorigenicity 2 is associated with endoscopic activity in patients with moderate-to-severe ulcerative colitis treated with golimumab [PDF]

, 2019
Suppressor of Tumorigenicity 2 (ST2) is an IL33 receptor detected in the mucosa and serum of ulcerative colitis (UC) patients. We evaluated soluble ST2 (sST2) as a surrogate biomarker of disease outcome and therapeutic response, in moderate-to-severe UC ...

Bioinspired Claw‐Engaged Adhesive Microparticles Armed with γGC Alleviate Ulcerative Colitis via Targeted Suppression of Macrophage Ferroptosis

Advanced Science, EarlyView.
γGC deficiency in ulcerative colitis drives macrophage ferroptosis‐mediated inflammation. Claw‐engaged microparticles armed with γGC (γGC‐MPs) enhance lesion targeting, promoting localized γGC release and tissue uptake. On the cover, Monkey King (Macrophages) was bound by the Immortal‐Binding Rope and subsequently sealed beneath the Five‐Fingered ...
