Hepatocarcinogenesis is under polygenic control. We analyzed gene expression patterns of dysplastic liver nodules (DNs) and hepatocellular carcinomas (HCCs) chemically-induced in F344 and BN rats, respectively susceptible and resistant to hepatocarcinogenesis. Expression profiles were performed by microarray and validated by quantitative RT-PCR and Western(More)
BACKGROUND Paragangliomas are rare neoplasms that originate from the neural crest. They are malignant in approximately 10% of cases, with a 50% survival rate at 5 years from diagnosis. In most cases, manifestations of malignancy (such as metastasis) are lacking, and paragangliomas are considered benign lesions. Pancreatic paragangliomas are extremely rare,(More)
INTRODUCTION Hepatic Portal Venous Gas (HPVG), a rare condition in which gas accumulates in the portal venous circulation, is often associated with a significant underlying pathology, such as Crohn's disease, ulcerative colitis, diverticulitis, pancreatitis, sepsis, intra-abdominal abscess, endoscopic procedures, mesenteric ischemia, abdominal trauma.

Previous studies showed that YAP1 is over-expressed in hepatocellular carcinoma (HCC). Here we observed higher expression of Yap1/Ctgf axis in dysplastic nodules and HCC chemically-induced in F344 rats, genetically susceptible to hepatocarcinogenesis, than in lesions induced in resistant BN rats. In BN rats, highest increase in Yap1-tyr357, p73(More)
INTRODUCTION Broncho-esophageal fistula is a rare clinical condition which can be manifested with non-specific signs and symptoms. PRESENTATION OF A CASE Here, we report an adult case of a broncho-esophageal fistula in a 43-year-old man referred for chronic cough after fluid food intake and weight loss. Barium swallow, esophagogastroduodenoscopy,(More)
Emerging evidence assigns to epigenetic mechanisms heritable differences in gene function that come into being during cell development or via the effect of environmental factors. Epigenetic deregulation is strongly involved in the development of hepatocellular carcinoma (HCC). It includes changes in methionine metabolism, promoter hypermethylation, or(More)
Liposarcomas are the most common of sarcoma tumours, they are usually located in the lower limbs, retroperitoneum, or abdominal cavity; up to date, only a few cases of omental liposarcoma with different histotype have been described. We present a case of omental well-differentiated liposarcoma and discuss imaging findings on ultrasound, computed tomography,(More)
