BACKGROUND AND OBJECTIVES Advanced ovarian cancer typically spreads in a diffuse intra-abdominal fashion. This characteristic suggests that combined radical surgery and intraperitoneal chemotherapy may be a useful treatment procedure. The purpose of this study was to review patients submitted to surgical debulking and hyperthermic intraoperative(More)
BACKGROUND AND OBJECTIVES Peritoneal carcinomatosis in women frequently has an ovarian origin. Hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) along with radical surgery/peritonectomy could present a new therapeutic approach with curative intention. The purpose of this research is to evaluate the role of the administration of HIPEC. (More)
p21WAF1/Cip1 is a recently identified gene involved in cell cycle regulation through cyclin-CDK-complex inhibition. The expression of this gene in several cell lines seems to be induced by wild-type, but not mutant, p53. p21WAF1/Cip1 expression has been studied at both mRNA and protein levels in a series of 49 normal mucosae and squamous cell carcinomas of(More)
AIMS In-vivo and in-vitro studies have shown that ethanol induces hepatocyte damage. The aim of the present study was to evaluate the effect of a broad range of ethanol concentrations on apoptosis and necrosis in primary culture of human and rat hepatocytes. METHODS Human and rat hepatocytes were isolated from human hepatectomies and male Wistar rats(More)
BACKGROUND AND AIMS An evaluation is made of the utility of fecal calprotectin in predicting relapse in patients with inflammatory bowel disease (IBD). The possible differences in its predictive capacity in Crohn's disease (CD) versus ulcerative colitis (UC), and the different phenotypes, are also examined. METHODS This is a prospective study with 135(More)
The pathogenic mechanisms underlying the progression of non-alcoholic fatty liver disease (NAFLD) are not fully understood. In this study, we aimed to assess the relationship between endoplasmic reticulum (ER) stress and autophagy in human and mouse hepatocytes during NAFLD. ER stress and autophagy markers were analyzed in livers from patients with(More)
Sterol regulatory element binding proteins (SREBPs) regulate the expression of a number of enzymes, which catalyze the synthesis of fatty acids, cholesterol, triglycerides, and phospholipids. SREBP1c is the most relevant isoform in the adult liver, and its expression is controlled by the nutritional state. Transcriptional regulation studies into the SREBP1c(More)
The pancreas is highly susceptible to the oxidative stress induced by ischemia/reperfusion (IR) injury leading to the generation of acute pancreatitis. Melatonin has been shown to be useful in the prevention of the damage by ischemia-reperfusion in liver, brain, myocardium, gut and kidney. The aim of the study was to evaluate the cytoprotective properties(More)
Mitochondria are involved in different physiological and pathological processes that are crucial for tumor cell physiology, growth and survival. Since cancer cells have frequently disrupted different cell death pathways that promote their survival, mitochondria may be key organelles to promote cell death in cancer cells. The present review is focused on the(More)
Serum IGF-I levels decline with age. We have recently reported that in aging rats the exogenous administration of IGF-I restores IGF-I circulating levels and age related-changes, improving glucose and lipid metabolisms, increasing testosterone levels and serum total antioxidant capability, and reducing oxidative damage in the brain and liver associated with(More)
