Variable Number of Tandem Repeats (VNTR) gene polymorphism of CYP2E1 in patients with pancreatic adenocarcinoma
2010
Context: The genetic polymorphism is considered a major source of variability, influencing the levels of gene expression. Cytochrome P450 2E1 (CYP2E1) is a mixed-function oxidase involved in the metabolism of the many endogenous and exogenous substances (ethanol, chemical carcinogens) in the hepatic and pancreatic tissue. CYP2E1 gene polymorphisms can cause various abilities of metabolize xenobiotic substances within a population with consequent increased susceptibility to various diseases,including cancer. One of the polymorphisms of the CYP2E1 gene is a VNTR (Variable Number Tandem Repeat) of some sequences in its "5 '- flanking region. Method : VNTR genotype CYP2E1 was determined by RFLP…
Ciprofloxacin Polymers Derived from Diallyltin and Divinyltin Dihalides
2008
The initial synthesis of condensation polymers from newly available divinyltin dichloride and diallyltin dichloride and ciprofloxacin is accomplished employing a modified interfacial polycondensation process. The polymeric (DP are about 2,000) products are rapidly (less than 15 seconds) formed in good yield. Infrared spectroscopy shows the formation of Sn-O and Sn-N bonds as predicted from the proposed structure. F-MALDI MS also shows ion fragments containing organotin in the predicted isotopic abundances as well as ion fragments containing both organotin and ciprofloxacin. The polymers exhibit low toxicity towards healthy WI-38 cells with variable toxicities towards a variety of cancer cel…
Tumor protein 53-induced nuclear protein 1 expression is repressed by miR-155, and its restoration inhibits pancreatic tumor development.
2007
Pancreatic cancer is a disease with an extremely poor prognosis. Tumor protein 53-induced nuclear protein 1 ( TP53INP1 ) is a proapoptotic stress-induced p53 target gene. In this article, we show by immunohistochemical analysis that TP53INP1 expression is dramatically reduced in pancreatic ductal adenocarcinoma (PDAC) and this decrease occurs early during pancreatic cancer development. TP53INP1 reexpression in the pancreatic cancer-derived cell line MiaPaCa2 strongly reduced its capacity to form s.c., i.p., and intrapancreatic tumors in nude mice. This anti-tumoral capacity is, at least in part, due to the induction of caspase 3-mediated apoptosis. In addition, TP53INP1 −/− mouse embryonic…
A Misunderstood intestinal perforation believed acute pancreatitis: A case report
2015
Acute pancreatitis represents one, possible but rare, of the several complications of laparoscopic cholecystectomy. In the case reported, a 31-year-old female patient complained of abdominal pain after laparoscopic cholecystectomy. The clinical picture, the high values of serum amylase, lipase and white blood cell count and the subsequent abdominal computed tomography (CT) led to diagnose an acute biliary pancreatitis. This was pharmacologically treated, but the patient worsened in a few days. A contrastenhanced CT showed the presence of free air and effusion into the peritoneal cavity. The patient was submitted to another intervention, which revealed a 1-cm jejunal perforation. The injured…
INCIDENZA DEL DIABETE MELLITO TIPO 2 DOPO TRAPIANTO COMBINATO RENE-PANCREAS
2009
Introduzione: Scopo di questo studio è determinare il tasso di incidenza del diabete mellito (DM) tipo 2 dopo trapianto combinato di rene-pancreas (SPK). Materiali e metodi: da Settembre 2000 a Gennaio 2008, è stato eseguito uno studio randomizzato a lungo termine, prospettico, in un singolo centro su 164 riceventi di SPK con drenaggio endocrino sistemico ed esocrino vescicale, comparando la rapamicina (Gruppo A, n=82) vs micofenolato mofetile (Gruppo B, n=82). La terapia all’induzione incluse in entrambi i gruppi l’uso di daclizumab (1mg/kg, 2 dosi) e timoglobulina (1mg/kg, 5 dosi). La terapia immunosoppressiva di mantenimento in entrambi i gruppi incluse inoltre tacrolimus e corticosteroi…
RITRAPIANTO DI PANCREAS DOPO RICORRENZA DI DIABETE MELLITO (DM) AUTOIMMUNE NEL PANCREAS TRAPIANTATO
2009
Introduzione: Il trapianto di pancreas rappresenta un trattamento efficace per la cura del diabete mellito (DM) tipo 1. Tuttavia alcuni pazienti sviluppano anticorpi anti-insule dopo il trapianto che sono in grado di distruggere il pancreas endocrino e culminare in DM ricorrente difficile da gestire. Materiali e metodi: uno studio retrospettivo è stato eseguito su pazienti che hanno ricevuto il ri-trapianto di pancreas per fallimento dell’organo trapiantato dopo trapianto combinato rene-pancreas (SPK) tra 1990 e 2008 presso il nostro centro. Furono analizzati i dati clinici, di laboratorio, istopatologici ottenuti dagli studi immunologici. Risultati: su un totale di 16 ri-trapianti di pancr…
Pseudocisti pancreatiche infette: Note di tecnica
2008
Introduction. Starting from the observation of 9 cases of giant infected pancreatic cysts, which occurred from 1994 to 2004 at the Department of Oncological and Surgical Studies, the Authors' aim has been to evaluate whether a more thorough necrosectomy, carried-out under videoendoscopic control, associated with a nose-gastro-cavity tube, which ensures a continuous cleansing of the newly-formed cavity, and an appropriate positioning of the drainages, could reduce the morbility and allow a shorter recovery of the infected psuodocysts. Patients and methods. Of 73 cases of acute pancreatitis, observed from 1994 to 2004, 9 showed severe and acute pancreatitis, which included giant pseudocysts, …
