BACKGROUND Obesity modulates inflammation and activation of immune pathways which can lead to liver complications. We aimed at identifying expression patterns of inflammatory and immune response genes specifically associated with obesity and NASH in the liver of morbidly obese patients. METHODOLOGY/PRINCIPAL FINDINGS Expression of 222 genes was evaluated(More)
BACKGROUND Quantification of hepatocyte death is useful to evaluate the progression of alcoholic liver diseases. Our aims were to quantify and correlate the circulating levels of Cytokeratin 18 (CK18) and its caspases-generated fragment to disease severity in heavy alcoholics. METHODOLOGY/PRINCIPAL FINDINGS CK18 and CK18-fragment were evaluated in the(More)
The incidence of chronic liver disease is constantly increasing, owing to the obesity epidemic. However, the causes and mechanisms of inflammation-mediated liver damage remain poorly understood. Endoplasmic reticulum (ER) stress is an initiator of cell death and inflammatory mechanisms. Although obesity induces ER stress, the interplay between hepatic ER(More)
BACKGROUND & AIMS The aim of this study was to determine the influence of coffee and other caffeinated drinks on liver fibrosis of severely obese European patients. METHODS A specific questionnaire exploring various types of coffee (regular filtrated coffee and espresso), caffeinated drinks, and chocolate was filled in by 195 severely obese patients. All(More)
Achondroplasia is a rare genetic disease characterized by abnormal bone development, resulting in short stature. It is caused by a single point mutation in the gene coding for fibroblast growth factor receptor 3 (FGFR3), which leads to prolonged activation upon ligand binding. To prevent excessive intracellular signaling and rescue the symptoms of(More)
BACKGROUND Osteopontin (OPN) plays an important role in the progression of chronic liver diseases. We aimed to quantify the liver, adipose tissue and serum levels of OPN in heavy alcohol drinkers and to compare them with the histological severity of hepatic inflammation and fibrosis. METHODOLOGY/PRINCIPAL FINDINGS OPN was evaluated in the serum of a(More)
BACKGROUND Non-invasive approaches are useful to differentiate simple steatosis from non-alcoholic steatohepatitis (NASH) in obese and morbidly obese patients. AIM To develop a new scoring system to diagnose definitive NASH. METHODS Preoperative clinical and biological data including serum caspase 3-generated cytokeratin-18 fragments (CK18) and surgical(More)
The intrauterine environment of the fetus is a preeminent actor in long-term health. Indeed, mounting evidence shows that maternal malnutrition increases the risk of type 2 diabetes (T2D) in progeny. Although the consequences of a disturbed prenatal environment on the development of the pancreas are known, the underlying mechanisms are poorly defined. In(More)
In Europe, human dirofilariasis refers to a group of autochtonous parasitic infections caused by tissue nematodes of the genus Dirofilaria, responsible for two distinct clinical presentations: Dirofilaria immitis usually presenting as pulmonary lesions and Dirofilaria repens as subcutaneous nodules. Rare in humans, genital involvement manifests itself as(More)
Positron emission tomography using radiolabeled amino acid (PET-AA) appears to be promising in distinguishing between recurrent tumour and radionecrosis in the follow-up of brain metastasis (BM). The amino acid transporter LAT1 and its cofactor CD98, which are involved in AA uptake, have never been investigated in BM. The aim of our study was to determine(More)
