BACKGROUND Progression of recurrent hepatitis C is accelerated in liver transplant recipients, leading to special need of non-invasive validated methods to estimate liver fibrosis. AIM To assess the efficacy of liver stiffness measurement by transient elastography (Fibroscan) and serum parameters in predicting fibrosis stage in HCV-infected transplant(More)
Primary liver sarcomatous carcinomas (PLSCs) are very aggressive tumors. They are characterized by a fast clinical course, and therefore need a prompt histological diagnosis. Here, we report two cases of PLSC. One arises in a non-cirrhotic liver and the other in cirrhosis, with differences in onset and histological features. Special emphasis is put on the(More)
The organic anion transporter peptides (OATP) 1B1 and 1B3 are hepatocytic-specific transporters determinant for the uptake of the contrast media Gd-EOB-DTPA during magnetic resonance, but variably lost in hepatocellular carcinoma (HCC). Here, we studied a series of HCCs from livers that underwent liver transplantation (OLT) and correlated the expression of(More)
Human aging is associated with a progressive loss of muscle mass and strength and a concomitant fat accumulation in form of inter-muscular adipose tissue, causing skeletal muscle function decline and immobilization. Fat accumulation can also occur as intra-muscular triglycerides (IMTG) deposition in lipid droplets, which are associated with perilipin(More)
INTRODUCTION Neoangiogenesis is crucial for the progression and vulnerability of atheromasic lesions. Since adult vasa vasorum, which represent the neoangiogenetic burden of healthy arteries, constitutively express Nestin and Wilms Tumor (WT1), the aims of the present study are: i) to describe and quantify Nestin and WT1 in plaque neovessels; ii) to(More)
AIMS In this paper we aimed to analyse the typology and the phenotype of the different vascular modifications in human hepatocellular carcinomas (HCCs) with a new immunomorphological and gene expression approach. We also attempted to correlate these modifications with the histological parameters of tumour aggressiveness and the surrounding liver parenchyma.(More)
Despite the central role of proteasomes in relevant physiological pathways and pathological processes, this topic is unexpectedly largely unexplored in human liver. Here we present data on the presence of proteasome and immunoproteasome in human livers from normal adults, fetuses and patients affected by major hepatic diseases such as cirrhosis and chronic(More)
Merkel cell carcinoma (MCC) of the skin is a neuroendocrine tumor with characteristic histological and immunohistochemical features. Among various cytogenetic changes, trisomy of chromosome 6 has been reported in 47% of cases using in situ hybridization. Primary tumors, morphologically and immunohistochemically identical to MCCs of the skin, have been(More)
Histological quality assessment of donated livers is a key factor for extending the cadaveric donor pool for liver transplantation. We retrospectively compared frozen-section analysis with routine histological permanent slides and the outcomes of grafts in liver biopsies from 294 candidate donors. The kappa concordance coefficient of agreement between(More)
Prostate cancer (CaP) represents the most prevalent malignancy in men more than 60-year-old, posing a problem in organ procurement from elderly subjects. However, most of the currently diagnosed CaP are low-grade and intraprostatic, with low metastatic risk, and there is recent evidence that most patients are overdiagnosed. The Italian National guidelines(More)
