Non-alcoholic fatty liver disease (NAFLD), most common chronic hepatic pathology, that occurs in the developed countries is estimated at 1/3 of the population. Amongst the numerous pathogenetic factors, oxidative stress and apoptosis of hepatocytes initiate many inflammatory processes and are involved in the progression of disease, particularly in(More)
We have described the unusual case of coexistence of membranous nephropathy resulting in nephrotic syndrome with systemic sclerosis. A 60-year-old patient was admitted to the Department of Nephrology with marked proteinuria and oedema. The renal biopsy specimen disclosed the features characteristic of membranous glomerulonephritis. The patient was treated(More)
Recent studies indicate the involvement of peroxisone proliferator-activated receptor-γ (PPAR-γ) in the inflammatory reaction. The exact mechanism of PPAR-γ action has not been elucidated. It is supposed that PPAR-γ regulates transcription of genes responsible for encoding cytokines involved in the inflammatory response. The latest studies, carried out to(More)
BACKGROUND The purpose of this experiment was to investigate the role of PPAR ligands in the course of inflammation and of rosiglitazone, a PPAR-gamma-specific agonist, on the course of experimental acute pancreatitis (EAP). MATERIAL/METHODS EAP was induced by administration of 5% sodium taurocholate injected into the pancreatic duct. The inflammatory(More)
BACKGROUND This study sought to define the mechanism by which PPAR-γ ligands affect the course of experimentally induced colitis in rats. MATERIAL/METHODS Inflammation was induced in Wistar rats by a single rectal administration of 2,4,6,-trinitrobenzene sulfonic acid (TNBS). The antagonist of PPARγ antagonist, bisphenol A diglycidyl ether (BADGE), was(More)
Pathogenesis of endometrial cancer has been connected with alterations of microRNA expression and in particular miR-205 up-regulation was consistently reported in this carcinoma. Presented study aimed to investigate if inhibition of miR-205 expression using LNA-modified-nucleotide would attenuate endometrial cancer cells proliferation in vitro and in(More)
PPAR-γ plays a role in the development of immune response, particularly in inflammation. The inflammatory reaction may be stimulated or suppressed by the presence of PPAR ligands. Some researchers suggest positive influence of the PPAR-γ agonist on suppression of the intestinal inflammatory process, yet there has not been much evidence showing that the(More)
PURPOSE The role of adenosine and its receptors in acute pancreatitis remains unelucidated. The aim was to evaluate the effects of the adenosine A2a receptor agonist and antagonist in the severe, taurocholate-induced experimental acute pancreatitis (EAP). MATERIAL AND METHODS The experiments were performed on 80 male Wistar rats, subdivided into 4 groups:(More)
The role of adenosine A3 receptors and their distribution in the gastrointestinal tract have been widely investigated. Most of the reports discuss their role in intestinal inflammations. However, the role of adenosine A3 receptor agonist in pancreatitis has not been well established. The aim of this study is [corrected] to evaluate the effects of the(More)
Non-specific inflammatory bowel diseases, including ulcerative colitis and Crohn`s disease, are chronic non-infectious diseases that showed an increase in prevalence in recent years, particularly in the developed countries. The effective methods of their treatment and prevention of recurrences are currently under investigation. One type of therapy that can(More)
