1. The ability of homogenates of jejunal mucosa to liberate amino acids from a peptic-tryptic digest of gluten was assessed. Mucosal specimens were obtained from thirty-two control subjects without malabsorptive disease, from twenty-six patients with untreated adult coeliac disease and from nine patients with adult coeliac disease in whom the intestinal mucosa was histologically normal as a con...
We have compared DNA methylation in normal colon mucosa between patients with colon cancer and patients without cancer. We identified significant differences in methylation between the two groups at 114 to 874 genes. The majority of the differences are in pathways involved in the metabolism of carbohydrates, lipids, and amino acids. We also compared transcript levels of genes in the insulin sig...
The effect of graded doses of pentagastrin on the gastric scretion of acid was compared in patients with and without gastritis. Biopsies were taken from the body of the stomach. Ten subjects had normal gastric mucosa, eight had superficial gastritis, and 10 atrophic gastritis. Pentagastrin in a dose of 1.5 mug/kg/hr elicited a near maximal HCl response from both the normal gastric mucosa and th...
AIM The aim of the study was to screen the markedly down-regulated proteins in colorectal cancer and analyze their relationship to carcinogenesis, cancer progression and pathological aspects. METHODS Proteomic analysis was preformed on six fresh colorectal cancer tissues and paired normal colorectal mucosa by two-dimensional differential gel electrophoresis and matrix-assisted laser desorptio...
Background: Recent research has provided evidences indicating the importance of endothelin axis in carcinogenesis. According to our knowledge, there are little information about endothelin A receptor (ETA) expression in oral squamous cell carcinoma (OSCC). So, the aim of the present study was to evaluate the immunohistochemical expression of ETA in OSCC and normal oral mucosa (...
BACKGROUND Anisakiasis is a parasitic disease caused primarily by Anisakis spp. larvae in Asia and in Western countries. The aim of this study was to investigate the genotype of Anisakis larvae endoscopically removed from Middle Eastern Japanese patients and to determine whether mucosal atrophy affects the risk of penetration in gastric anisakiasis. METHODS In this study, 57 larvae collected ...
BACKGROUND High-resolution microendoscopy (HRME) enables real-time imaging of epithelial tissue. The utility of this novel imaging modality for inverted papilloma has not been previously described. This study examines the ability of otolaryngologists to differentiate between images of inverted papilloma and normal sinonasal mucosa obtained with a HRME. METHODS Inverted papilloma and normal si...
AIM OF THE STUDY To investigate the expression status and association of β-catenin and AXIN2 in ameloblastoma. MATERIAL AND METHODS 30 ameloblastoma specimens and 10 normal oral mucosa tissues were enrolled in the study. The protein and RNA levels of β-catenin and AXIN2 were detected by immunohistochemistry staining, Western blot, and real-time PCR analysis. The relationship between β-catenin...
OBJECTIVE TRAF3 and TRAF5 share a common ancestral gene, and interact as essential components of signaling pathways in immunity. TRAF3 and TRAF5 are overexpressed in the colon of rat/mouse models with colitis. However, the expressions of TRAF3 and TRAF5 in patients with inflammatory bowel disease have not been elucidated. The aim of the present study is to explore the potential roles of TRAF3 a...
OBJECTIVE Oral mucosal epithelia of smokers and waterpipe users are more susceptible to malignant alterations. The aim of this study was morphometric evaluation of the effects of using waterpipe on normal oral mucosa. MATERIALS AND METHODS IN A CROSS SECTIONAL STUDY, CYTOLOGIC SMEAR SAMPLES FROM THE FOLLOWING THREE DIFFERENT AREAS: buccal mucosa, lateral surface of the tongue, and floor of th...
