OBJECTIVES: A non-alcoholic fatty liver disease (NAFLD) has high prevalence and now important issue of public health. In general, there exists strong interaction between NAFLD and diabetes, but the detailed mechanism is unclear. In this study, we determined the effects of hyperglycemia on progression in the early phase of NAFLD in mice. METHODS: Male ddY mice were fed a choline-deficient, l-amino acid-defined, high-fat diet (CDAHFD) consisting of 60% of kcal from fat and 0...

We report the first documented case of malignant melanoma obstructing ureters of both moieties of a duplex kidney and contralateral single moiety ureter in a 51-year-old male. The patient presented with fever, coryzal symptoms and liver function test derangement several years after two superficial spreading melanomas were excised with clear margins. Ultrasonography demonstrated hydronephroureter in both moieties of a complete right-sided duplex kidney. Retrograde pyelograms showed bilateral hydronephroureter and filling defects in all three ureters...

The role of physical interventions (surgical resection and surgical/radiological ablation) for liver metastases of colorectal cancer has changed dramatically over the last 10-15 years. Whereas in the 1990s, when only those patients with up to three unilobar metastases were considered for any form of such intervention, our present approach to these physical interventions is determined by how much viable disease-free liver can be preserved (most authorities accepting 25-30% disease-free future remnant liver volume) and the possibility of further such interventions if the disease recurs in the liver...

BACKGROUND: Contrast-enhanced ultrasound (CEUS) is a valuable tool in the diagnostic approach of focal liver lesions, but occasionally subjective and observer-dependent. Semiquantitative evaluation of dynamic CEUS (DCEUS) with standardised software programmes such as Dynamic Vascular Pattern (DVP) could help to improve diagnostic accuracy and objectivity in liver tumour assessment. OBJECTIVES: The present study aimed at evaluation of diagnostic accuracy of DVP in a clinical setting...

Exosomes are emerging mediators of intercellular communication; whether the release of exosomes has an effect on the exosome donor cells in addition to the recipient cells has not been investigated to any extent. Here, we examine different exosomal miRNA expression profiles in primary mouse colon tumour, liver metastasis of colon cancer and naive colon tissues. In more advanced disease, higher levels of tumour suppressor miRNAs are encapsulated in the exosomes. miR-193a interacts with major vault protein (MVP)...

Neoplastic hilar obstruction to the liver outflow presents a unique challenge to the surgeon, wherein, the balance between a curative and possibly larger resection has to be achieved against a more conservative local resection. These are often technically demanding and have thus, far produced equivocal outcomes on both ends. The present case series is on 13 patients who presented with hilar obstruction. They all underwent resections with possible curative intent. The focus of our review is on the technical nuances and the strategies we used, intra- and peri-operatively to make resections possible in these patients, who at first look were deemed inoperable...

Gastrointestinal stromal tumours (GISTs) are mesenchymal tumours of the digestive tract, derived from Cajal interstitial cells. Bone metastases are very rare, and there is no consensus regarding their treatment. Here, we present the unusual case of a 66-year-old man with a gastric GIST with synchronous bone and liver metastases, fully documented at the pathological and molecular levels with a KIT exon 11 mutation. After 9 months of imatinib, the scanner showed a 33% partial response of target lesions. We also review the literature and describe the characteristics, treatment, and outcome of all cases previously reported...

Virtually all cells in the organism secrete extracellular vesicles (EVs), a heterogeneous population of lipid bilayer membrane-enclosed vesicles that transport and deliver payloads of proteins and nucleic acids to recipient cells, thus playing central roles in cell-cell communications. Exosomes, nanosized EVs of endosomal origin, regulate many pathophysiological processes including immune responses and inflammation, tumour growth, and infection. Healthy subjects and patients with different diseases release exosomes with different RNA and protein contents into the circulation, which can be measured as biomarkers...

Hepatocellular carcinoma (HCC) cells often invade the portal venous system and subsequently develop into portal vein tumour thrombosis (PVTT). Long noncoding RNAs (lncRNAs) have been associated with HCC, but a comprehensive analysis of their specific association with HCC metastasis has not been conducted. Here, by analysing 60 clinical samples' RNA-seq data from 20 HCC patients, we have identified and characterized 8,603 candidate lncRNAs. The expression patterns of 917 recurrently deregulated lncRNAs are correlated with clinical data in a TCGA cohort and published liver cancer data...

Tumour necrosis factor alpha (TNF-α) is one kind of cytokines which is related to inflammation and lipid metabolism. TNF-α cDNA was cloned from the liver of blunt snout bream (Megalobrama amblycephala) through real-time polymerase chain reaction (PCR) and rapid amplification of cDNA ends (RACE) methods. The full-length cDNA of TNF-α covered 1467 bp, with an open reading frame (ORF) of 723 bp, which encodes 240 amino acids. It possessed the TNF family signature IIIPDDGIYFVYSQ. After the lipopolysaccharide (LPS) challenge test, a graded tissue-specific expression pattern of TNF-α was observed and there was high expression abundance in the kidney, brain and liver...

PURPOSE: Recurrent disease following thermal ablation therapy is a frequently reported problem. Preoperative identification of patients with high risk of recurrent disease might enable individualized treatment based on patients' risk profile. The aim of the present work was to investigate the role of metabolic parameters derived from the pre-ablation (18)F-FDG PET/CT as imaging biomarkers for recurrent disease in patients with colorectal liver metastases (CLM). METHODS: Included in this retrospective study were all consecutive patients with CLM treated with percutaneous or open thermal ablation therapy who had a pre-treatment baseline (18)F-FDG PET/CT available...
