The objective is using saliva instead of plasma for pregabalin therapeutic drug monitoring (TDM) since saliva reflects the free non-protein bound drug concentration, simple and noninvasive sampling, cheaper and does not require the expertise of drawing blood. Forty four patients participated in this study, two samples of saliva and another two of blood were taken from each patient; first sample of both saliva and blood is the trough sample and was taken just before the first dose of the day and second sample is the peak sample and was taken 1 h after taking the first dose of the day...

BACKGROUNDS: The intestinal microbiota is considered as a potential common underpinning pathophysiology of Functional Gastrointestinal Disorders (FGIDs) and psychiatric disorders such as depression and anxiety. Fecal Microbiota Transplantation (FMT) has been reported to have therapeutic effects on diseases related to dysbiosis, but few studies have evaluated its effect on psychiatric symptoms. METHODS: We followed 17 patients with either Irritable Bowel Syndrome (IBS), Functional Diarrhea (FDr) or Functional Constipation (FC) who underwent FMT for the treatment of gastrointestinal symptoms and observation of psychiatric symptoms...

Colitis is a chronic inflammation and ulcer on the inner lining of the large intestine. For many centuries Ocimum gratissimum (OG) leaves have been used in folk medicine in Nigeria to treat inflammatory bowel diseases, however, to date, the anti-colitis effects of OG have not been scientifically proven. In this study we investigated the effects of polyphenol rich extract of Ocimum gratissimum (PREOG) leaf on colonic mucosa injury in colitis, its mechanisms, initial administration time and dosage. Dextran sodium sulfate (DSS)-induced rat colitis models was used...

Ulcerative colitis (UC) is a chronic idiopathic disease affecting the colon. Patients with UC display a number of alterations in immune-related molecules and cells, as well as dysbiosis in the intestinal microbiota. It remains unclear whether the alterations in the patients' immune systems are initiating factors of UC or a result from external insults. Also, precisely how these intestinal microorganisms affect UC development is not completely understood. To answer these questions, fecal bacteria were collected from UC patients during the active phase (UC-active), UC patients during the remission phase (UC-remission), and healthy controls...

INTRODUCTION: Diagnosing lymphoma continues to prove challenging in the clinical practice. Composite lymphoma (CL) is defined by the coexistence of different lymphoma subtypes in the same anatomical location. This condition has seldom been witnessed in the gastrointestinal (GI) tract. We weren't able to find previous cases in the literature about small bowel CL with follicular lymphoma (FL) and classical Hodgkin lymphoma (CHL). Surgery is the treatment of choice to obtain accurate histology, to manage and prevent acute complications...

IL-21 is a much studied cytokine that has been implicated in the regulation of TH1, TH2, TH17 and regulatory immune responses; its signalling is a promising therapeutic target for autoimmune, inflammatory and infectious diseases. Despite its biological importance, measuring IL-21 reliably has proved difficult. ELISAs are commonly used to measure cytokines in various biological samples. However, results obtained are only as good as the quality of the sample. Here, we show that when using fresh samples, a significant increase in IL-21 was measured in the intestinal homogenate of mice infected with the intestinal worm Heligmosomoides polygyrus...

The tripeptides, Ile-Pro-Pro (IPP) and Leu-Lys-Pro (LKP), inhibit angiotensin-converting enzyme (ACE) resulting in lowered blood pressure. Our hypothesis was that the medium chain fatty acid permeation enhancer, sodium caprate (C10 ), may prevent the decrease in permeability of the tripeptides when PepT1 is inhibited by glycyl-sarcosine (Gly-Sar), a situation that may occur in the presence of food hydrolysates. Using Caco-2 monolayers and isolated rat jejunal tissue, the apparent permeability coefficients (Papp ) of [3 H]-IPP and [3 H]-LKP were assessed in the presence of Gly-Sar with and without C10 ...

Non-alcoholic fatty liver disease (NAFLD) is characterized by excessive fat deposition in the liver in the absence of significant alcohol consumption. Dysregulated bile acid (BA) metabolism is an important indicator in the pathology of NAFLD, which could progress into more severe forms of liver injury. Lipid metabolism, immune environment and intestinal bacteria are all affected by dysregulated BA metabolism directly, but the mechanisms remain unclear. Several drug candidates that target BA metabolism, either used alone or in combination with other agents, are currently under development for treatment of NAFLD...

The cDNA of EcSOD (designated as NaEcSOD), cloned and characterized from Nibea albiflora for the first time, was 1101 bp in length including 5'-untranslated region (UTR) of 224 bp, 3' UTR of 229 bp, and an open reading frame (ORF) of 648 bp encoding a polypeptide of 215 amino acids. Based on the results of GST pull-down assay and mass spectrometric identifications, a membrane protein (annexin A4) was found to specifically bind with NaEcSOD, indicating that the two proteins might be involved in antagonizing reactive oxygen species (ROS) together...

A purified neutral exopolysaccharide (EPS) designated as EPS0142 was obtained from Lactobacillus plantarum JLK0142. EPS0142 consisted of glucose and galactose in an approximate molar ratio of 2.13:1.06 and had a molecular weight of 1.34 × 105  Da. The FT-IR spectrum showed that EPS0142 had a typical polysaccharide absorption pattern. 1 H NMR and 13 C NMR spectra analysis showed the presence of N-acetylated sugar residues. EPS0142 had no toxic effects on RAW 264.7 cells and significantly improved their phagocytic activity and NO secretion in vitro...

Global characterization of tissue proteomes from small amounts of biopsy material has become feasible due to advances in mass spectrometry and bioinformatics tools. In celiac disease (CD), dietary gluten induces an immune response which is accompanied by pronounced remodeling of the small intestine. Removal of gluten from the diet abrogates the immune response and the tissue architecture normalizes. In this study differences in global protein expression of small intestinal biopsies from CD patients were quantified by analyzing formalin-fixed, paraffin-embedded material using liquid-chromatography mass spectrometry and label-free protein quantitation...

Inflammatory bowel disease (IBD) is associated with a number of immune-mediated extra-intestinal manifestations. Over half of all IBD patients have some form of respiratory pathology, most commonly neutrophil-mediated diseases such as bronchiectasis and chronic bronchitis. Using murine models of colitis, we aimed to identify the immune mechanisms driving pulmonary manifestations of IBD. We found increased neutrophil numbers in lung tissue associated with the pulmonary vasculature in both trinitrobenzenesulfonic acid- and dextran sulfate sodium-induced models of colitis...

During development, the embryo transitions from a metabolism favoring glycolysis to a metabolism favoring mitochondrial respiration. How metabolic shifts regulate developmental processes, or how developmental processes regulate metabolic shifts, remains unclear. To test the requirement of mitochondrial function in developing endoderm-derived tissues, we genetically inactivated the mitochondrial transcription factor, Tfam, using the Shh-Cre driver. Tfam mutants did not survive postnatally, exhibiting defects in lung development...

The human gut microbiome refers to a highly diverse microbial ecosystem, which has a symbiotic relationship with the host. Molecular hydrogen (H2) and carbon dioxide (CO2) are generated by fermentative metabolism in anaerobic ecosystems. H2 generation and oxidation coupled to CO2 reduction to methane or acetate help maintain the structure of the gut microbiome. Bile acids are synthesized by hepatocytes from cholesterol in the liver and are important regulators of host metabolism. In this Review, we discuss how gut bacteria metabolize hydrogen gases and bile acids in the intestinal tract and the consequences on host physiology...

Ebulin f is a ribosome-inactivating protein (RIP) present in green fruits of the dwarf elder (Sambucus ebulus L). Since dwarf elder fruits are used for food and as a medicine, we assessed the study of toxicological effects and safety of ebulin f in elderly mice, comparing these results with those reported in young animals and with other RIPs. Female Swiss mice aged 6 and 12 months of age were intraperitoneally injected with a single dose from 1.4 to 4.5 mg/kg ebulin f. Heart, stomach, intestines, lung, kidney, liver, spleen, pancreas, adrenal gland, uterus, ovary and brain were studied...

Enterohemorrhagic E. coli (EHEC) O157:H7, which is a foodborne pathogen that causesdiarrhea, hemorrhagic colitis (HS), and hemolytic uremic syndrome (HUS), colonize to the intestinal tract of humans. To study the detailed mechanism of EHEC colonization in vivo, it is essential to have animal models to monitor and quantify EHEC colonization. We demonstrate here a mouse-EHEC colonization model by transforming the bioluminescent expressing plasmid to EHEC to monitor and quantify EHEC colonization in living hosts...

Until recently, our understanding of the cellular tropism of human norovirus (HuNoV), a major cause of viral gastroenteritis, has been limited. Immune cells and intestinal epithelial cells (IECs) have been proposed as targets of HuNoV replication in vivo, although the contribution of each to pathogenesis and transmission is unknown. Murine norovirus (MNV) is widely used as a surrogate model for HuNoV, as it replicates in cultured immune cells. The importance of the complete MNV immune cell tropism in vivo has not been determined...
