Enterococcus species, principally Enterococcus faecium are used as probiotics since a long time with preference in animal applications but safety considerations were updated and also new uses as probiotics can be envisaged. Fifteen Enterococcus strains isolated from different foods were identified and analyzed for virulence factors and antibiotic resistance. Three Enterococcus durans strains were selected to study their immunomodulatory properties on PBMC and Caco2 cells. Two strains presented a profile toward a mild inflammatory Th1 response considering TNF-α/IL-10 and IL-1β/IL-10 cytokines ratios...

Dieulafoy's lesions of the Jejunum are extremely rare. Therefore, localization of lesions is very difficult due to their small size and tendency of occasional bleeding. However, it is important to mention the location of the Dieulafoy's lesions to prevent excessive intestinal resections or, even worse, resection of the normal intestine. We report a case of preoperative localization of a Dieulafoy's lesion embolized by a metallic coil that allows a surgeon to accurately identify the bleeding, permitting a minimally invasive surgical treatment...

OBJECTIVE: To assess long-term renal preservation and surgical outcomes in patients undergoing ureteric substitution with ileum. This has been a mainstay of reconstruction options for lengthy ureteral defects. METHODS: Consecutive patients aged 18 or older undergoing ileal ureters at our institution were retrospectively reviewed (1989-June 2013). Patients with <6 months of follow-up were excluded. Demographic, surgical and renal functional outcomes were reviewed...

BACKGROUND: We introduced a rat model of ischemic enteritis and investigated the roles of enterobacteria, nitric oxide (NO), and prostaglandins (PGs) in its pathogenesis. METHODS: Male rats were used after 18 h of fasting. Ischemic enteritis was induced by partial ligation of the superior mesenteric artery (SMA). Under ether anesthesia, SMA was isolated, and a stenosis was made by placing a needle (23 guage) on the vessel and ligating both the vessel and needle, and then a needle was removed from the ligature...

Increasing evidence supports the view that intestinal farnesoid X receptor (FXR) is involved in glucose tolerance and that FXR signaling can be profoundly impacted by the gut microbiota. Selective manipulation of the gut microbiota-FXR signaling axis was reported to significantly impact glucose intolerance, but the precise molecular mechanism remains largely unknown. Here, caffeic acid phenethyl ester (CAPE), an over-the-counter dietary supplement and an inhibitor of bacterial bile salt hydrolase, increased levels of intestinal tauro-β-muricholic acid, which selectively suppresses intestinal FXR signaling...

BACKGROUND: The precise mechanisms controlling homing of T effector (Teff) cells to the inflamed gut in Crohn's disease (CD) are still unclear, and clinical outcome data from patients with inflammatory bowel disease treated with the anti-α4β7 integrin antibody vedolizumab suggest differences between ulcerative colitis and CD. METHODS: Expression of homing molecules was studied with flow cytometry and immunohistochemistry. Their functional role was investigated in in vitro adhesion assays and in a humanized mouse model of T cell homing to the inflamed gut in vivo...

BACKGROUND: Ulcerative colitis (UC) only involves the colonic mucosa. Yet, nearly 50% of patients with UC who undergo total proctocolectomy with ileal pouch anal anastomosis develop UC-like inflammation of the ileal pouch (pouchitis). By contrast, patients with familial adenomatous polyposis (FAP) with ileal pouch anal anastomosis develop pouchitis far less frequently. We hypothesized that pathogenic events associated with the development of UC are recapitulated by colonic-metaplastic transcriptomic reprogramming of the UC pouch...

Background: In different models of paralytic ileus, cannabinoid receptors are overexpressed and endogenous cannabinoids are massively released, contributing to gastrointestinal dysmotility. The antitumoral drug vincristine depresses gastrointestinal motility and a similar mechanism could participate in this effect. Therefore, our aim was to determine, using CB1 and CB2 antagonists, whether an increased endocannabinoid tone is involved in vincristine-induced gastrointestinal ileus. Methods: First, we confirmed the effects of vincristine on the gut mucosa, by conventional histological techniques, and characterized its effects on motility, by radiographic means...

A paracaecal hernia, a type of pericaecal hernias, is a rare cause of small intestinal obstruction. Failure of early recognition and reduction of this type of internal hernia may lead to strangulation of the herniated intestine. There has been a number of case reports in the literature about the different types of pericaecal hernias, however the anatomy of these hernias is still poorly understood and the management is still evolving. We are presenting a 75year old woman, who presented clinically and radiologically with distal small intestinal obstruction...

Qing-Hua Granule (QHG), the modified formulation of a classical Chinese prescription named Gegen Qinlian Decoction, was clinically employed to treat type 2 diabetes mellitus (T2DM) through regulation of glucagon-like peptide-1 (GLP-1). However, the potential mechanism is unknown. We investigate whether QHG induces GLP-1 secretion via activation of bitter taste receptor (TAS2R) pathway in the gastrointestinal tract of db/db mice. The db/db mice were intragastrically (i.g.) administered QHG (low/medium/high dose) once daily for 8 weeks...

YghJ, also known as SslE (Secreted and surface associated lipoprotein) is a cell surface associated and secreted lipoprotein harbouring M60 metalloprotease domain. Though the gene is known to be conserved among both pathogenic and commensal Escherichia coli isolates, the expression and secretion of YghJ was found to be higher among diverse E. coli pathotypes. YghJ, secreted from intestinal pathogens such as enterotoxigenic E. coli (ETEC) and enteropathogenic E. coli (EPEC) has been demonstrated to possess mucinase activity and hence facilitates colonization of these enteric pathogens to intestinal epithelial cells...

Carcinoid tumor is the most common neuroendocrine tumor affecting the gastrointestinal tract. The coexistence of multifocal carcinoid lesions is a well-established phenomenon. Although intubation of the terminal ileum is not routinely attempted during colonoscopy, it can occasionally reveal the presence of some incidental findings. We present a patient with known rectal carcinoid, who was found to have another carcinoid lesion in the terminal ileum during surveillance colonoscopy. The patient underwent right hemicolectomy, and no chemotherapy was required as the patient was found to have stage 1 carcinoid tumor...

BACKGROUND: Richter's hernia is a high-risk ischaemic gastrointestinal disorder that is typically diagnosed in a delayed manner due to a lack of obvious symptoms. Spontaneous umbilical enterocutaneous fistula (ECF) resulting from an incarcerated Richter's hernia is extremely rare. CASE PRESENTATION: A 62-year-old female presented with a chief complaint of recurrent umbilical region infection for the preceding 20 months with no symptoms of ileus. Preoperative CT and fistulography revealed an incarcerated Richter's hernia complicated by an ECF...

BACKGROUND: Diarrhea-predominant irritable bowel syndrome (IBS-D) is a functional gastrointestinal (GI) disorder, which occurs more frequently in women than men. The aim of our study was to determine the role of activation of classical estrogen receptors (ER) and novel membrane receptor, G protein-coupled estrogen receptor (GPER) in human and mouse tissue and to assess the possible cross talk between these receptors in the GI tract. METHODS: Immunohistochemistry was used to determine the expression of GPER in human and mouse intestines...
