Hepatocellular carcinoma (HCC) accounts for the majority of primary liver cancers. Clearly identifiable risk factors are lacking in up to 30% of HCC patients and most of these cases are attributed to non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH). Beyond the known risk factors for NAFLD, the intestinal microbiota, in particular dysbiosis (defined as any change in the composition of the microbiota commonly found in healthy conditions) is emerging as a new factor promoting the development of chronic liver diseases and HCC...

Turtle blood flukes belonging to the family Spirorchiidae (Digenea) represent a major threat for sea turtle health and are considered the most important parasitic cause of turtle stranding and mortality worldwide. Despite the large diversity of spirorchiid species found globally, there are only 2 records for free-ranging Mediterranean sea turtles that date back to the late 1800s involving just Hapalotrema mistroides Monticelli, 1896. This study describes the first fatal confirmed case of spirorchiidiasis in a free-ranging Mediterranean loggerhead turtle Caretta caretta (Linnaeus) and, owing to the complexities of taxonomic identification of these parasites, provides the first molecular characterization and phylogenetic analysis of H...

PURPOSE: We previously reported that TU-100 suppresses irinotecan hydrochloride (CPT-11)-induced inflammatory cytokines and apoptosis. However, the mechanism underlying this effect has not been fully elucidated. The aim of this study was to further clarify the mechanism of CPT-11-induced bacterial translocation (BT) and the effect of TU-100 on BT. METHODS: Cell cytotoxicity was assessed in vitro by a WST-8 assay. For the in vivo experiments, rats were randomly divided into 3 groups: the control group, the CPT-11 group (250 mg/kg i...

BACKGROUND: The incidence of inflammatory bowel diseases (IBD) is increasing worldwide with patients experiencing severe impacts on their quality of life. It is well accepted that intestinal inflammation associates with extensive damage to the enteric nervous system (ENS), which intrinsically innervates the gastrointestinal tract and regulates all gut functions. Hence, treatments targeting the enteric neurons are plausible for alleviating IBD and associated complications. Mesenchymal stem cells (MSCs) are gaining wide recognition as a potential therapy for many diseases due to their immunomodulatory and neuroprotective qualities...

CXCL12 has been shown to be involved in colon cancer metastasis, but its expression level and molecular mechanisms regulating its expression remain controversial. We thus evaluated CXCL12 expression in a large cohort of colon adenomas and carcinomas, investigated for an epigenetic mechanism controlling its expression and evaluated the impact of CXCL12 levels on cell migration and tumor growth. CXCL12 expression was measured in human colon adenomas and carcinomas with transcriptome array and RT-qPCR. The promoter methylation was analyzed with whole-genome DNA methylation chips and protein expression by immunohistochemistry...

Anthelmintic drugs require effective concentrations to be attained at the site of parasite location for a certain period to assure their efficacy. The processes of absorption, distribution, metabolism and excretion (pharmacokinetic phase) directly influence drug concentrations attained at the site of action and the resultant pharmacological effect. The aim of the current review article was to provide an overview of the relationship between the pharmacokinetic features of different anthelmintic drugs, their availability in host tissues, accumulation within target helminths and resulting therapeutic efficacy...

BACKGROUND: Within seven days following peroral high dose infection with Toxoplasma gondii susceptible conventionally colonized mice develop acute ileitis due to an underlying T helper cell (Th) -1 type immunopathology. We here addressed whether mice harboring a human intestinal microbiota developed intestinal, extra-intestinal and systemic sequelae upon ileitis induction. METHODOLOGY/PRINCIPAL FINDINGS: Secondary abiotic mice were generated by broad-spectrum antibiotic treatment and associated with a complex human intestinal microbiota following peroral fecal microbiota transplantation...

As an ecological niche, the mammalian intestine provides the ideal habitat for a variety of bacterial microorganisms. Purportedly, some commensal genera and species offer a beneficial mix of metabolic, protective, and structural processes that help sustain the natural digestive health of the host. Among these sort of gut inhabitants is the Gram-positive lactic acid bacterium Lactobacillus ruminis, a strict anaerobe with both pili and flagella on its cell surface, but also known for being autochthonous (indigenous) to the intestinal environment...

There is general consensus that enteroendocrine cells, EEC, containing the enteric hormone cholecystokinin (CCK) are confined to the small intestine and predominate in the duodenum and jejunum. Contrary to this, EEC that express the gene for CCK have been isolated from the large intestine of the mouse and there is evidence for EEC that contain CCK-like immunoreactivity in the mouse colon. However, the human and rat colons do not contain CCK cells. In the current study, we use immunohistochemistry to investigate CCK peptide presence in endocrine cells, PCR to identify cck transcripts and chromatography to identify CCK peptide forms in the mouse small and large intestine...

Primary mesenteric adenocarcinoma (PMA) is a rare malignant disease. A case of PMA that was covered by an abscess of the mesocolon and intestinal obstruction is reported in the present study. As the onset site of PMA is often obscured or hidden, there may be no clinical symptoms in the early stage. At the advanced stage, the tumor size is large enough to induce intestinal obstruction, perforation, bleeding, volvulus and other clinical symptoms in the majority of patients. Computed tomography scans, ultrasound and other auxiliary examinations are not sufficiently accurate for diagnosing PMA with non-specific characteristics in the majority of cases, causing certain difficulties in the pre-operative diagnosis of PMA, which easily lead to misdiagnosis...

BACKGROUND: Ischemia-reperfusion (I/R) injury causes the dysfunctions of different major organs, leading to morbidity and mortality on the global scale. Among a battery of therapeutic targets, the heme oxygenase-1 (HO-1)/carbon monoxide (CO) system has been evaluated for the development of new therapies against I/R injury. The enzyme HO-1 catalyzes the degradation of heme into three biologically active end products, namely biliverdin/bilirubin, CO and ferrous ion. Interestingly, CO is one of a few bioactive gaseous molecules with the capability of regulating inflammation, cell survival and growth...

BACKGROUND: Celiac disease is one of the most common diseases in the world. Capsule endoscopy is an alternative way to visualize the entire small intestine without invasiveness to the patient. It is useful to characterize celiac disease, but hours are need to manually analyze the retrospective data of a single patient. Computer-aided quantitative analysis by a deep learning method helps in alleviating the workload during analysis of the retrospective videos. METHOD: Capsule endoscopy clips from 6 celiac disease patients and 5 controls were preprocessed for training...

AIM: To develop an electromyography method for pregnant rat uterus in vivo and to separate myometrial signals from the gastrointestinal tract signals. METHODS: Pregnant Sprague-Dawley rats (n=8) were anaesthetized and their stomach, small intestine, and large intestine were removed from the abdomen. A pair of thread electrodes was inserted into the uterus, while a pair of disk electrodes was placed subcutaneously above the myometrium. Additionally, a strain gauge sensor was fixed on the surface of the myometrium and cecum for the parallel detection of mechanical contractions in rats (n=18) with intact gastrointestinal tract...

INTRODUCTION: Stricture formation is a common long-term complication of Crohn's disease. Endoscopic balloon dilatation offers a bowel-sparing treatment option, but long-term outcome and its association with patient-, stricture-, and procedure-related factors is only poorly understood. Patient satisfaction with endoscopic balloon dilatation is largely unknown. METHODS: We performed a retrospective review of all endoscopic balloon dilatation for Crohn's disease-related strictures between January 2005 and January 2013...

Altered gastric accommodation and intestinal morphology suggests impaired gastrointestinal (GI) transit may occur in the Wistar Kyoto (WKY) rat strain, as common in stress-associated functional GI disorders. Because changes in GI transit can alter microbiota composition, we investigated whether these are altered in WKY rats compared with the resilient Sprague Dawley (SD) rats under basal conditions, and characterized plasma lipid and metabolite differences. Bead transit was tracked by X-ray imaging to monitor: gastric emptying (GE; 4 h), small intestine (SI) transit (9 h) and large intestine transit (12 h)...

The existing large number of gene expression profiles of tumour samples offers a great advantage for the integrative functional genomic exploration of molecular dysregulation in cancers. The clusters of genes (modules) derived from a gastric cancer (GC) coexpression network were explored to understand their clinical and functional significance. Among the modules derived from the GC mRNA expression network, six modules were relatively highly expressed in diffuse type gastric tumours. Elevated expression of genes related to extracellular matrix (ECM), angiogenesis, collagen and intracellular cytoskeletal components and immune response were identified in these modules...
