The first effects of 3,4-methylen-dioxy-metamphetamine (MDMA, "ecstasy"), on serotonin 1A (5-HT(1A)) receptors in rat hippocampus were determined by means of [(3)H]-8-hydroxy-dipropylamino-tetralin ([(3)H]-8-OH-DPAT) and 5'guanosine-(gamma-[(35)S]-thio)triphosphate ([(35)S]-GTPgammaS) binding as well as inhibition of forskolin (FK)-stimulated adenylyl(More)
Data on neurobiological mechanisms underlying mood disorders are elusive; the aetiology of such states is multifactorial, including genetic predisposition and environmental factors. Diagnosis is currently being made only on an interview-based methodology. Biological markers, which could improve the current classification, and in perspective, stratify(More)
BACKGROUND Proteomic research in the field of parathyroid tissues is limited by the very small dimension of the glands and by the low incidence of cancer lesions (1%). Formalin-fixed paraffin-embedded (FFPE) tissue specimens are a potentially valuable resource for discovering protein cancer biomarkers. In this study we have verified the applicability of a(More)
OBJECTIVE The aim of the present study was to analyze if alterations of peripheral-type benzodiazepine receptor (PBR) characteristics occurred in platelet membranes of patients affected by primary fibromyalgia (FM). DESIGN AND METHODS Platelets were obtained from 30 patients with FM. Evaluation of kinetic parameters of PBR was performed using [(3)H](More)
Sjögren's syndrome (pSS) is a systemic disease that affects salivary glands directly, and is therefore expected to influence the composition of human whole saliva (WS) fluid. The aim of this study was to characterize the WS proteins of pSS patients using a proteomic approach to assess a valid procedure to examine the global changes of the salivary protein(More)
In rat striatum A(2A) adenosine receptors activate adenylyl cyclase through coupling to G(s)-like proteins, mainly G(olf) that is expressed at high levels in this brain region. In this study we report that the sulfhydryl alkylating reagent, N-ethylmaleimide (NEM), causes a concentration- and time-dependent inhibition of [3H](More)
OBJECTIVE Fibromyalgia (FM) is characterized by the presence of chronic widespread pain throughout the musculoskeletal system and diffuse tenderness. Unfortunately, no laboratory tests have been appropriately validated for FM and correlated with the subsets and activity. The aim of this study was to apply a proteomic technique in saliva of FM patients: the(More)
In the last few years, a growing interest has arisen in the application of proteomic analysis to rheumatic disease. Sjögren's syndrome is a systemic disease that affects exocrine glands directly, and is therefore expected to influence the composition of the whole human saliva and lachrymal fluid. Therefore, a rising number of studies have been performed in(More)
PURPOSE Malignant mesothelioma is a neoplastic disease linked to asbestos exposure whose diagnosis is limited, so detection methods for an early diagnosis and treatment result essential. Here, we compared proteomic profiles of malignant pleural mesothelioma (MPM) and benign biopsies to search potential biomarkers useful in differential diagnosis. (More)
The clinical entity of secondary Sjögren's syndrome (SS) is controversial and the relationship with primary SS and other systemic autoimmune diseases is still far from being completely understood. In the last few years, proteomic approaches have been applied with a growing interest in the search for diagnostic biomarkers for many rheumatic diseases and it(More)
