Background/Aims: Atrophic gastritis is considered a premalignant lesion. We aimed to evaluate the risk factors for gastric tumorigenesis in underlying mucosal atrophy. Methods: A total of 10,185 subjects who underwent upper gastrointestinal endoscopy between 2003 and 2004 were enrolled in this retrospective cohort study. Follow-up endoscopy was performed between 2005 and 2014. Atrophic gastritis and intestinal metaplasia were assessed by endoscopy using the Kimura-Takemoto classification...

INTRODUCTION: Ogilvie's Syndrome or Acute Colonic Pseudo-Obstruction (ACPO) is a rare condition characterized by massive dilatation of the colon in the absence of mechanical obstruction. About 10% of all reported cases are related to Obstetric and Gynaecological procedures, Caesarean section being the commonest associated factor. Acute intestinal dilatation, if not treated, may lead to perforation and faecal peritonitis with consequent high morbidity and mortality. MATERIALS AND METHODS: An electronic literature searches were performed in PubMed, EMBASE, Google scholar and hand searches for relevant references were included without any language restriction...

BACKGROUND AND AIMS: Barley kernel based products have been shown to induce benefits on blood glucose regulation, cardio-metabolic risk markers and appetite regulating hormones in a time perspective of 11-16 h after intake. The mechanisms have been assigned to gut fermentation of indigestible carbohydrates. The purpose of the present study was to evaluate if the modulatory effects of barley on markers of metabolic- and appetite regulation are affected by a dietary background including a mixture of commercially available probiotics...

Enterotoxigenic Escherichia coli (ETEC), defined by their elaboration of heat-labile (LT) and/or heat-stable (ST) enterotoxins, are a common cause of diarrheal illness in developing countries. Efficient delivery of these toxins requires ETEC to engage target host enterocytes. This engagement is accomplished using a variety of pathovar-specific and conserved E. coli adhesin molecules as well as plasmid encoded colonization factors. Some of these adhesins undergo significant transcriptional modulation as ETEC encounter intestinal epithelia, perhaps suggesting that they cooperatively facilitate interaction with the host...

REVIEW
Arjan Jonker, Peiqiang Yu
Forages grown in temperate regions, such as alfalfa (Medicago sativa L.) and white clover (Trefolium repens L.), typically have a high nutritional value when fed to ruminants. Their high protein content and degradation rate result, however, in poor utilization of protein from the forage resulting in excessive excretion of nitrogen into the environment by the animal. Proanthocyanindins (also known as condensed tannins) found in some forage legumes such as birdsfoot trefoil (Lotus corniculatus L.), bind to dietary protein and can improve protein utilization in the animal...

Ectopic varices include all varices except esophageal or gastric varices and comprise large portosystemic venous collaterals that occur anywhere in the abdomen. Ectopic varices are relatively rare; however, approximately 5% are related to gastrointestinal bleeding. Ectopic varices usually occur in the rectum, duodenum, or colon, and portal hypertension is the most common cause. Hemodynamic profiles of ectopic varices remain unknown, and extensive bleeding from these structures occurs because diagnosis and treatment are difficult...

TCRαβ(+)CD4(-)CD8α(+)CD8β(-) intestinal intraepithelial lymphocytes (CD8αα IELs) are an abundant population of thymus-derived T cells that protect the gut barrier surface. We sought to better define the thymic IEL precursor (IELp) through analysis of its maturation, localization and emigration. We defined two precursor populations among TCRβ(+)CD4(-)CD8(-) thymocytes by dependence on the kinase TAK1 and rigorous lineage-exclusion criteria. Those IELp populations included a nascent PD-1(+) population and a T-bet(+) population that accumulated with age...

The transcriptional programs that guide lymphocyte differentiation depend on the precise expression and timing of transcription factors (TFs). The TF BACH2 is essential for T and B lymphocytes and is associated with an archetypal super-enhancer (SE). Single-nucleotide variants in the BACH2 locus are associated with several autoimmune diseases, but BACH2 mutations that cause Mendelian monogenic primary immunodeficiency have not previously been identified. Here we describe a syndrome of BACH2-related immunodeficiency and autoimmunity (BRIDA) that results from BACH2 haploinsufficiency...

Chronic liver disease with cirrhosis is the 12th leading cause of death in the United States, and alcoholic liver disease accounts for approximately half of all cirrhosis deaths. Chronic alcohol consumption is associated with intestinal bacterial dysbiosis, yet we understand little about the contribution of intestinal fungi, or mycobiota, to alcoholic liver disease. Here we have demonstrated that chronic alcohol administration increases mycobiota populations and translocation of fungal β-glucan into systemic circulation in mice...

Breads prepared from cereal grains are a dietary staple, providing a significant proportion of daily energy, but not necessarily of dietary protein. However, good digestibility of proteins in bread is important to avoid potential immunogenic effects of undigested peptides, including for those gluten-intolerant. Four gluten-containing (white wheat, wholemeal wheat, spelt and rye) and four gluten-free (chick pea, lupin, buckwheat, amaranth) flours were used to make yeast-leavened breads standardized for protein...

Nature-made inherent transporting property of beta-lactoglobulin (BLG) was exploited to develop delivery systems for quercetin. After binding to BLG, quercetin was nanoencapsulated within soft-condensed nanostructures of BLG and sodium alginate (ALG). Fluorimetry results revealed that quercetin could bind to BLG even at acidic conditions. The amounts of stoichiometry binding (n) were 1.24 and 1.62 at pH values of 4 and 7, respectively. Formation of core-shell type nanostructures was confirmed by transmission electron microscopy...

Bariatric surgery continues to be a durable therapeutic option for a growing number of obese patients. The patients that are admitted to our hospital for elective bariatric procedures often suffer from multiple co-morbidities and are therefore treated with a significant number of chronic medications. These operations lead to drastic modifications of the anatomy and physiology of the gastro-intestinal tract that may change the pharmacokinetics of drugs. In addition, the natural post-operative course of a bariatric procedure may lead to amelioration or even resolution of some of the obesity-related chronic diseases, consequently eliminating the need for drug therapy...

The abnormality being the result of a certain transposition of the large intestine winding in between diaphragm and the liver, owes it's name to a so called Chilaiditi symptom. This symptom is rarely recognized for at most 0,025-0,28% of the whole population statistics - wise. The Chilaiditi symptom can be examined without any serious (abdominal) pain indication, when conducting the gastrointestinal examination with the implication of the different disorders. When carrying out the diagnostic examination, it is strongly recommended to take notice of patients suffering from the pain in abdominal area, especially in case of the patients with the developed air - structure under the right side copula of the diaphragm...

Quercetin is an abundant flavonoid in fruits, vegetables such as onion, tea leaves, cranberry, radish leaves etc. with numerous biological activities and widely used as an effective antioxidant. Its low solubility in water and chemical decomposition in intestinal environment are predicaments in delivery through dietary or oral intake. Noble polymeric nanoparticles are of particular interest today because of their applications in many areas. Polymer nanoparticles have attracted the interest of many research groups and have been utilised in an increasing number of fields such as site targeted drug delivery in cancer research during the last decades...

Under normal physiological conditions, the intestinal immunity remains largely hyporesponsive to the commensal microbiota, yet also retains the inherent ability to rapidly respond to pathogenic antigens. However, immunomodulatory activities of extracellular products from commensal bacteria have been little studied, with previous investigations generally utilizing the live bacterium to study microbiota-epithelial interactions. In this study, we demonstrate that extracellular products of a commensal bacterium, Escherichia coli C25, elicit a moderate release of proinflammatory IL-8 and stimulate transcriptional up-regulation of Toll-like receptors (TLRs) in intestinal epithelial cell lines HT29-19A and Caco-2...

Akkermansia muciniphila is an abundant inhabitant of the intestinal tract of humans and many other animals. It is the sole intestinal representative of the verrucomicrobia in human stools and depleted in adults suffering from obesity, diabetes and several other diseases. A. muciniphila degrades intestinal mucin into mainly propionic and acetic acid, and lives in symbiosis with its host, marked by signalling to immune and metabolic pathways, priming trophic chains and likely providing competitive exclusion at the host-microbe interface...

BACKGROUND: Osteoarthritis (OA) is the most common form of arthritis and is caused by degeneration of the joint cartilage and growth of new bone, cartilage and connective tissue. It is often associated with major disability and impaired quality of life. There is currently no consensus on the best treatment to improve OA symptoms. Celecoxib is a selective non-steroidal anti-inflammatory drug (NSAID). OBJECTIVES: To assess the clinical benefits (pain, function, quality of life) and safety (withdrawals due to adverse effects, serious adverse effects, overall discontinuation rates) of celecoxib in osteoarthritis (OA)...

There is compelling evidence linking the commensal intestinal microbiota with host health and, in turn, antibiotic induced perturbations of microbiota composition with distinct pathologies. Despite the attractiveness of probiotic therapy as a tool to beneficially alter the intestinal microbiota, its immunological effects are still incompletely understood. The aim of the present study was to assess the efficacy of the probiotic formulation VSL#3 consisting of eight distinct bacterial species (including Streptococcus thermophilus, Bifidobacterium breve, B...
