Several recent studies have illustrated the beneficial effects of living in an enriched environment on improving human disease. In mice, environmental enrichment (EE) reduces tumorigenesis by activating the mouse immune system, or affects tumor bearing animal survival by stimulating the wound repair response, including improved microbiome diversity, in the tumor microenvironment. Provided here is a detailed procedure to assess the effects of environmental enrichment on the biodiversity of the microbiome in a mouse colon tumor model...

Polymorphonuclear neutrophil-derived microparticles (PMN)-MPs) are lipid bilayer, spherical microvesicles with sizes ranging from 50-1,000 nm in diameter. MPs are a newly evolving, important part of cell-to-cell communication and signaling machinery. Because of their size and the nature of their release, until recently MP existence was overlooked. However, with improved technology and analytical methods their function in health and disease is now emerging. The protocols presented here are aimed at isolating and characterizing PMN-MPs by flow cytometry and immunoblotting...

Percutaneous suprapubic cystostomy (SPC) is a procedure performed to manage urinary retention when urethral catheterization is contraindicated or to improve the quality of life in cases such as neurogenic bladder. Although a simple procedure, it is associated with serious complications, increasing the morbidity and mortality. This case study demonstrates a delayed presentation of small bowel obstruction caused by a suprapubic catheter traversing through the ileal mesentery in a patient with no prior bowel surgeries...

The pathogenesis and key functional molecules involved in inflammatory bowel disease (IBD) including Crohn's disease (CD) and ulcerative colitis (UC) remain unclear. Here, we reported that Erbin, a protein required for the polarity of epithelial cells, is conserved across species and highly expressed in the intestinal mucosa in mice and zebrafish. Pathologically, Erbin expression in the intestinal mucosa was significantly decreased in DSS induced acute colitis mice, IL-10 deficient mice and clinical biopsy specimens from patients with ulcerative colitis...

Placement of percutaneous jejunostomy tubes using fluoroscopy may be technically challenging because of the peristaltic motion of small bowel loops within the peritoneum. Furthermore, fluoroscopic jejunostomy placement has an inherent risk of complications, including peritonitis and death. A transnasal snare technique to facilitate direct jejunostomy in patients with a surgically altered gastric anatomy has been previously reported. This report describes a patient with gastroparesis and a chronic nasojejunal tube who underwent a percutaneous transgastric snare technique to facilitate the placement of a direct jejunostomy...

Intestinal angioedema is a rare side effect of angiotensin-converting enzyme inhibitors. We present a 41-year-old woman with sporadic right lower quadrant abdominal pain and diarrhea with multiple computed tomography scans demonstrating enteritis. Suspicion turned to angiotensin-converting enzyme inhibitor use as the cause for the patient's illness after an extensive negative evaluation including labs, stool studies, endoscopies, and capsule endoscopy. Weeks after stopping the medication, the patient's symptoms improved and repeat computed tomography showed a resolution of the previously seen findings of enteritis...

BACKGROUND AND PURPOSE: Prostate stereotactic body radiotherapy (SBRT) regimens differ in time, dose, and fractionation. We completed a multicentre, randomized phase II study to investigate the impact of overall treatment time on quality of life (QOL). MATERIAL AND METHODS: Men with low and intermediate-risk prostate cancer were randomly assigned to 40 Gy in 5 fractions delivered once per week (QW) vs. every other day (EOD). QOL was assessed using the Expanded Prostate Cancer Index Composite...

Subtraction hybridization identified genes displaying differential expression as metastatic human melanoma cells terminally differentiated and lost tumorigenic properties by treatment with recombinant fibroblast interferon and mezerein. This approach permitted cloning of multiple genes displaying enhanced expression when melanoma cells terminally differentiated, called melanoma differentiation associated (mda) genes. One mda gene, mda-7, has risen to the top of the list based on its relevance to cancer and now inflammation and other pathological states, which based on presence of a secretory sequence, chromosomal location, and an IL-10 signature motif has been named interleukin-24 (MDA-7/IL-24)...

<br>Introduction The gastrointestinal tract and pancreas are common primary sites for neuroendocrine tumours (NETs). Patients often report long duration of non-specific symptoms in the year prior to diagnosis. The aims of this study were to establish pre-diagnosis patterns of symptoms. Secondly, to determine the time from onset of symptoms to NET diagnosis and understand the interaction with primary and secondary healthcare providers. Method A survey was designed on a web-based survey platform with the focus on patient symptoms prior to diagnosis and a screen for functional diarrhoea (Rome III criteria (C4))...

Serum neutrophil gelatinase-associated lipocalin (NGAL) is a low molecular weight protein released from activated neutrophils and intestine epithelium whose mRNA expression is increased in inflamed intestinal tissue. The purpose of this study was to explore the relationship between serum NGAL level and activity of inflammatory bowel diseases. A total of 120 patients, 79 with Crohn's disease (CD) and 41 with ulcerative colitis (UC) were prospectively included into the study. Serum NGAL was measured by ELISA...

The mucosal response to injury can best be understood as a complex layering of different responses that may be invoked depending upon the size and nature of the injury, the persistence of the injurious stimulus, and the availability of various trophic host factors that stimulate repair. There is a hierarchy of responses that ranges from small rapid resealing of acute apical membrane or single cell wounds through the long term attempt to heal a giant peptic ulcer or respond to inflammatory bowel disease. Although much previous attention has been paid to the local factors that regulate these pathways and responses, there is increasing interest in systemic factors that may act either by the production of cytokines and trophic factors or by the direct migration of bone marrow derived stem cells into the mucosal wound...

Abdominal pregnancies represent 1.4% of extrauterine pregnancies. A literature search of six cases involving bowel ectopic pregnancies provided anecdotal treatment options. This case involves a woman admitted at 6 weeks gestation with right iliac fossa and shoulder tip pain. An ultrasound scan revealed an empty uterus with free fluid in both adnexa and a 31×21 mm heterogenous mass adjacent to the right ovary. At laparoscopy, an ectopic pregnancy was identified at the hepatic flexure. The patient received two doses of methotrexate and monitored until the beta human chorionic gonadotropin reduced...

Fbw7 is a type of E3 ubiquitin ligase that targets various proteins for degradation and has been found to have a high expression level in progenitor cells. Deletion of Fbw7 in the intestine results in the accumulation of progenitor cells. Moreover, Fbw7 loss increases the susceptibility of colorectal cancer. However, the involvement of Fbw7 in the progress and development of inflammatory bowel disease (IBD) is still controversial. To identify the function of Fbw7 on dextran sodium sulfate (DSS)-induced colonic inflammation, we generated Fbw7ΔG mice, lacking Fbw7 specifically in intestinal epithelium...

Recent evidence suggests that renal tubular injury plays a key role in deterioration of renal function in both chronic kidney disease (CKD) and acute kidney injury (AKI). Since commonly used biochemical indicators such as GFR, serum creatinine, blood urea nitrogen and creatinine clearance are inappropriate for detecting alteration in renal tubules, biomarkers reflecting renal tubular injury have been extensively explored. Our research group identified leucine rich α-2 glycoprotein (LRG) as a novel serum biomarker for various inflammatory diseases such as rheumatoid arthritis and inflammatory bowel disease...

Inflammatory bowel disease (IBD) is an idiopathic disease caused by a dysregulated immune response to intestinal microbes in an individual with a genetic predisposition. Therefore, alleviation of inflammation is very important to treat IBD. Mesenchymal stem cells (MSCs) have been highlighted as new candidates for treating autoimmune disease based on their immunomodulatory properties. In this study, we investigated the anti-inflammatory mechanism and therapeutic effects of adipose tissue-derived MSCs (ASCs) using THP-1 macrophages and dextran sodium sulfate (DSS)-induced mice with chronic colitis...
