MiR‐146a‐5p Suppresses M1 Polarization of Tumor‐Associated Macrophages via IRAK1/NF‐κB Signaling in Colorectal Polyps

Annals of Gastroenterological Surgery, EarlyView.
MiR‐146a‐5p is downregulated in colorectal polyps, leading to IRAK1 upregulation and NF‐κB activation, which promotes M1 macrophage polarization and inflammation. Overexpression of miR‐146a‐5p suppresses IRAK1/NF‐κB signaling, reduces M1 polarization, and alleviates inflammatory responses.

Uncovering Cystic Fibrosis Carrier: Insights From a Heterozygous CFTR‐F508del Rabbit Model

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis (CRS) is a heterogeneous inflammatory disorder frequently associated with impaired mucociliary clearance and bacterial infection. Individuals carrying a single cystic fibrosis transmembrane conductance regulator (CFTR) mutation exhibit partial CFTR dysfunction and are increasingly recognized as being at risk ...

Biofilm Exoproteins From Staphylococcus Species Impede Re‐Epithelialization of Nasal Epithelial Cells During Wound Healing and Cease Ciliary Beat Frequency

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Introduction Chronic rhinosinusitis (CRS) is an inflammatory disease with many different contributing factors, including bacterial infection. CRS patients are typically managed with medical therapies; however, these treatments frequently fail, leaving surgery as the only viable option.

Interspecies Biofilm Dynamics Among Staphylococci: Inflammatory Contributions to Chronic Rhinosinusitis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Introduction Staphylococcus species are frequently isolated from the sinonasal niche of chronic rhinosinusitis (CRS) patients. While Staphylococcus aureus is often associated with recalcitrant CRS, Staphylococcus epidermidis and Staphylococcus lugdunensis are largely deemed commensal.

KRAS and BRAF somatic mutations in colonic polyps and the risk of metachronous neoplasia. [PDF]

PLoS ONE, 2017
High-risk features of colonic polyps are based on size, number, and pathologic characteristics. Surveillance colonoscopy is often recommended according to these findings. This study aimed to determine whether the molecular characteristics of polyps might

A novel technique using endoscopic band ligation for removal of long-stalked (>10 mm) pedunculated colon polyps: A prospective pilot study

The Saudi Journal of Gastroenterology, 2021
Background: Endoscopic removal of large and thick-stalked pedunculated colonic polyps, often leads to massive hemorrhage. Several techniques to minimize this complication have not been widely adopted due to some caveats.

Roux‐en‐Y gastrojejunostomy and jejunojejunostomy for pyloric obstruction bypass in a horse and a foal

Equine Veterinary Journal, EarlyView.
Abstract Background Gastric outflow obstruction in horses is a rare but challenging condition, often resulting from either congenital anomalies or acquired lesions such as chronic ulceration or pyloric polyps. Conventional surgical bypass procedures, including gastrojejunostomy (GJ) or gastroduodenostomy and less commonly duodenojejunostomy, can ...
