BACKGROUND Alzheimer's Disease (AD) is the most common neurodegenerative disease and the leading cause of dementia among senile subjects. It has been proposed that AD can be caused by defects in mitochondrial oxidative phosphorylation. Given the fundamental contribution of the mitochondrial genome (mtDNA) for the respiratory chain, there have been a number(More)
The clock gene machinery controls cellular metabolism, proliferation, and key functions, such as DNA damage recognition and repair. Dysfunction of the circadian clock is involved in tumorigenesis, and altered expression of some clock genes has been found in cancer patients. The aim of this study was to evaluate the expression levels of core clock genes in(More)
PURPOSE A tumour score for venous invasion in patients with pancreatic adenocarcinoma was evaluated by means of computed tomography (CT), in order to improve the assessment of medical treatment and clinical outcome with special attention to borderline resectable disease. MATERIALS AND METHODS Fifty-six consecutive patients who underwent curative surgical(More)
BACKGROUND AND AIM Altered expression of microRNAs (miRNAs) hallmarks many cancer types. The study of the associations of miRNA expression profile and cancer phenotype could help identify the links between deregulation of miRNA expression and oncogenic pathways. METHODS Expression profiling of 866 human miRNAs in 19 colorectal and 17 pancreatic cancers(More)
PURPOSE Controversy prevails on the impact of preoperative biliary drainage (PBD) on postoperative complications and clinical outcome of pancreatic cancer. We determined whether PBD is associated with increased morbidity and mortality rates after pancreaticoduodenectomy. METHODS A total of 131 consecutive patients who underwent pancreaticoduodenectomy (93(More)
OBJECTIVES Despite advances in clinical management of pancreatic cancer (PC), there is still room for improvement in early detection, diagnosis, and treatment strategies. The role of microRNAs (miRNAs) in tumor biology might pinpoint an alteration in expression of miRNAs as new diagnostic/prognostic biomarkers. METHODS Expression levels of miR-143 and(More)
Pancreatic cancer (PC), the fourth leading cause of cancer-related deaths, is characterized by high aggressiveness and resistance to chemotherapy. Pancreatic carcinogenesis is kept going by derangement of essential cell processes, such as proliferation, apoptosis, metabolism and autophagy, characterized by rhythmic variations with 24-h periodicity driven by(More)
Pancreatic ductal adenocarcinoma (PDAC) is one of the most deadly cancers, being the fourth leading cause of cancer-related deaths. Long-term survival reaching 15% is achieved in less than 5% of patients who undergo surgery, and median survival is only 6 months in those with inoperable lesions. A deeper understanding of PDAC biologic characteristics as well(More)
Pancreatic ductal adenocarcinoma (PDAC) is an extremely aggressive malignancy, characterized by largely unsatisfactory responses to the currently available therapeutic strategies. In this study we evaluated the expression of genes involved in gemcitabine uptake in a selected cohort of patients with PDAC, with well-defined clinical-pathological features.(More)
BACKGROUND AND AIM The neuropeptide Substance P, plays a key role in modulating neuroimmune interactions in patients with inflammatory bowel diseases. We analyzed Substance P serum levels in patients with ulcerative colitis and Crohn's disease, to detail the involvement of the neuropeptide in the pathophysiology of these disorders. METHODS Serum samples(More)
