The yqiC gene of Salmonella enterica serovar Typhimurium (S. Typhimurium) regulates bacterial growth at different temperatures and mice survival after infection. However, the role of yqiC in bacterial colonization and host immunity remains unknown. We infected human LS174T, Caco-2, HeLa, and THP-1 cells with S. Typhimurium wild-type SL1344, its yqiC mutant, and its complemented strain. Bacterial colonization and internalization in the four cell lines significantly reduced on yqiC depletion. Post-infection production of interleukin-8 and human β-defensin-3 in LS174T cells significantly reduced because of yqiC deleted in S...

Although fructose was discovered in 1794, it was realised in recent decades only that its malabsorption can lead to intestinal symptoms while its excessive consumption induces metabolic disturbances. Fructose is a monosaccharide found naturally in most fruits and vegetables. Dietary intake of fructose has gradually increased in the past decades, especially because of the consumption of high fructose corn syrup. With its 16.4 kg/year consumption, Hungary ranks secondly after the United States. Fructose is absorbed in the small intestine by facilitated transport mediated by glucose transporter proteins-2 and -5, and arrives in the liver cells...

Vibrio cholerae is the causative agent of cholera, an acute diarrheal disease that remains endemic in many parts of the world. The mechanisms underlying immunity to cholera remain poorly defined, though it is increasingly clear that protection is associated with antibodies against lipopolysaccharide (LPS). Here we report that ZAC-3, a monoclonal antibody against the core/lipid A region of V. cholerae LPS is a potent inhibitor of V. cholerae flagellum-based motility in viscous and liquid environments. ZAC-3 arrested motility of the classical Ogawa strain O395, as well as the El Tor Inaba strain C6706...

Anecdotal and scientific evidence suggests that Cannabis use may be beneficial in inflammatory bowel disease (IBD) patients. Here, we have investigated the effect of a standardized Cannabis sativa extract with high content of cannabidiol (CBD), here named CBD BDS for "CBD botanical drug substance," on mucosal inflammation and hypermotility in mouse models of intestinal inflammation. Colitis was induced in mice by intracolonic administration of dinitrobenzenesulfonic acid (DNBS). Motility was evaluated in the experimental model of intestinal hypermotility induced by irritant croton oil...

BACKGROUND: Electroacupuncture (EA) at acupoint ST 37 (Shangjuxu) has been used to alleviate gastrointestinal symptoms and improve gastrointestinal motility. However, the mechanisms by which EA affects the enteric nervous system (ENS) have scarcely been investigated. In this study, we investigated whether EA could improve ENS function. METHODS: A constipation model was established by gastric instillation of ice-cold saline daily for 14 days. The constipated mice were divided into two groups: the model group, which was not treated, and the EA group, which received EA at ST 37 at a frequency of 2-15 HZ and an amplitude of 1 mA for 15 min a day for 3 days...

BACKGROUND: Caesarean sections (CS) are the most frequent major surgery in the world. A transient impairment of bowel motility is expected after CS. Although this usually resolves spontaneously within a few days, it can cause considerable discomfort, require symptomatic medication and delay hospital discharge, thus increasing costs. Chewing gum in the immediate postoperative period is a simple intervention that may be effective in enhancing recovery of bowel function in other types of abdominal surgeries...

Diverticular disease (DD) is a common gastrointestinal condition. Clinical spectrum ranges from asymptomatic diverticulosis to symptomatic uncomplicated or complicated DD. Symptoms related to uncomplicated DD are not specific and may be indistinguishable from those of irritable bowel syndrome. Low-grade inflammation, altered intestinal microbiota, visceral hypersensitivity, and abnormal colonic motility have been identified as factors potentially contributing to symptoms. Probiotics may modify the gut microbial balance leading to health benefits...

The vagus nerve is a major component of the autonomic nervous system and plays a critical role in many body functions including for example, speech, swallowing, heart rate and respiratory control, gastric secretion, and intestinal motility. Vagus nerve stimulation (VNS) refers to any technique that stimulates the vagus nerve, with electrical stimulation being the most important. Implantable devices for VNS are approved therapy for refractory epilepsy and for treatment-resistant depression. In the case of heart disease applications, implantable VNS has been shown to be beneficial for treating heart failure in both preclinical and clinical studies...

Lipopolysaccharide (LPS) exists in the outer membrane of Gram-negative bacteria. Colorectal normal epithelium and colorectal cancer cells in situ are continuously exposed to LPS from intestinal bacteria, while little is known about the influence of LPS on colorectal cancer progression and metastasis. In this study, we investigated the potential role of LPS on colorectal cancer progression and metastasis as well as the underlying mechanisms. We measured higher LPS concentration in colorectal cancer tissues and even higher LPS concentration in colorectal cancer tissues with lymph node metastasis...

Clostridium difficile is the principal cause of nosocomial infectious diarrhoea worldwide. The pathogen modifies its flagellin with either a type A or type B O-linked glycosylation system, which has a contributory role in pathogenesis. We study the functional role of glycosyltransferases modifying type B flagellin in the 023 and 027 hypervirulent C. difficile lineages by mutagenesis of five putative glycosyltransferases and biosynthetic genes. We reveal their roles in the biosynthesis of the flagellin glycan chain and demonstrate that flagellar post-translational modification affects motility and adhesion-related bacterial properties of these strains...

INTRODUCTION: Intussusception in adult is rarely caused by idiopathic conditions. Main causes are inflammatory diseases, benign or malignant tumors and motility disorders. As a benign cause, lipomas appear as a particularly rare gastrointestinal intraluminal tumor occurring with highest incidence in the colon, mostly in the caecum and ascending colon. PRESENTATION OF CASE: A 57-year-old male patient was admitted at the surgical emergency in Belo Horizonte, with history of chronic and intermittent diffuse abdominal pain, associated with variations of his bowel habits and rare episodes of vomiting starting around 3days prior to admission...

BACKGROUND: The antineoplastic drug 5-fluoruracil (5-FU) is a pirimidine analog, which frequently induces potentially fatal diarrhea and mucositis. Cannabinoids reduce gastrointestinal motility and secretion and might prevent 5-FU-induced gut adverse effects. Here, we asked whether cannabinoids may prevent diarrhea and mucositis induced by 5-FU in the rat. METHODS: Male Wistar rats received vehicle or the non-selective cannabinoid agonist WIN 55,212-2 (WIN; 0.5 mg kg(-1) injection(-1) , 1 injection day(-1) , 4 consecutive days) by intraperitoneal (ip) route; on the first 2 days, animals received also saline or 5-FU (150 mg kg(-1) injection(-1) , cumulative dose of 300 mg kg(-1) )...

Patients with end-stage renal disease (ESRD) show a high incidence of bacterial translocation and impaired gastrointestinal motility. The intestinal tract is believed to be the most crucial source of translocated bacteria. To evaluate the risk of colonic diverticulitis in patients with ESRD, we conducted a nationwide population-based cohort study. Patients who met the following 3 criteria were defined as patients with ESRD: patients diagnosed with ESRD who received regular hemodialysis between 2000 and 2005, patients who received hemodialysis for more than 90% of the time during the observation period (2000-2011), and patients with no prior history of hemodialysis between 1997 and 1999...
