Background: Refractory Coeliac Disease (RCD) is characterized by persisting mucosal pathology in spite of a strict gluten free diet (GFD). In RCD type II phenotypically aberrant (CD7+CD3-CD4/8-cytoplasmicCD3+) T-lymphocytes are present within the Intraepitelial Lymphocyte (IEL) population in the small intestine, and 50-60% of these patients develops an Enteropathy Associated T-cell lymphoma (EA...
Little is known regarding the potential risk posed by aerosolized prions. Chronic wasting disease (CWD) is transmitted horizontally, almost surely by mucosal exposure, and CWD prions are present in saliva and urine of infected animals. However, whether CWD may be transmissible by the aerosol or nasal route is not known. To address this question, FVB mice transgenetically expressing the normal c...
TGF-β Signaling Pathways in Different Compartments of the Lower Airways of Patients With Stable COPD
BACKGROUND The expression and localization of transforming growth factor-β (TGF-β) pathway proteins in different compartments of the lower airways of patients with stable COPD is unclear. We aimed to determine TGF-β pathway protein expression in patients with stable COPD. METHODS The expression and localization of TGF-β pathway components was measured in the bronchial mucosa and peripheral lu...
Solitary rectal ulcer syndrome (SRUS) is an uncommon poorly understood benign disorder of defecation. SRUS may simulate other disorders such as inflammatory bowel disease andneoplasms. Histopathological analysis forms the cornerstone of diagnosis for SRUS.Key histological features include fibromuscular obliteration of the lamina propria with splaying of the muscularis mucosae upward between the...
the purpose of this study is to describe the histological and histochemical features of digestive tract intwo aquarium fishes with different types of feeding habits which are omnivorous (walking catfish) andcarnivorous (piranha), respectively. five adult walking catfish (l: 26.4 ± 3.4 cm, w: 265 ± 55 g) and fiveadult piranha (l: 23.6 ± 4.5 cm, w: 247 ± 50 g) were used for this study. the fishes...
chitosan-graft-polyethylenimine (chi-g-pei) copolymer has been used for theimprovement of low transfection efficiency of chitosan. the present study aims to test thepulmonary toxicity and efficiency of chi-g-pei as an aerosol gene carrier. mice were exposedto aerosol containing green-fluorescent protein (gfp)-polyethylenimine (pei) or gfp-chig-pei complexes for 30 min during the development of ...
The intrinsic neural networks of the gastrointestinal tract are derived from dedicated neural crest progenitors that colonize the gut during embryogenesis and give rise to enteric neurons and glia. Here, we study how an essential subpopulation of enteric glial cells (EGCs) residing within the intestinal mucosa is integrated into the dynamic microenvironment of the alimentary tract. We find that...
The ultrastructural features associated with vascular permeability in 9 cases of advanced gastric carcinomas were studied, and compared with that of control non-neoplastic mucosa. Tumour microvasculature showed features in common with those of control mucosa, including complete basal lamina, well-developed interendothelial junctions, fenestrations and caveolae. Some tumour blood vessels showed ...
PETRINEC, Z., S. NEJEDLI, S. KUŽIR, A. OPAČAK: Mucosubstances of the digestive tract mucosa in northern pike (Esox lucius L.) and european catfish (Silurus glanis L.). Vet. arhiv 75, 317-327, 2005. ABSTRACT The distribution and quality of mucosubstances in the digestive tract of pike (Esox lucius) and catfish (Silurus glanis) is described. The digestive tract of pike and catfish is short, in ac...
