In vivo administration or in vitro application of dopamine or of dopamine receptor agonists induce vasodilatation in the cerebral, coronary, renal and mesenteric vascular beds and cause hypotension. Moreover, dopamine stimulates cardiac contractility and induces diuresis and natriuresis. Peripheral (cardiovascular and renal) dopamine receptors belong to the(More)
Cholinergic markers and the expression of M(2)-M(5) muscarinic cholinergic receptor subtypes were investigated in human peripheral blood lymphocytes by Western blot analysis and immunocytochemistry. The totality of peripheral blood lymphocytes express acetylcholine (ACh) immunoreactivity, choline acetyltransferase (ChAT), acetylcholinesterase (AChE),(More)
We evaluated comorbidity, hospitalization, and mortality in chronic obstructive pulmonary disease (COPD), with special attention to risk factors for frequent hospitalizations (more than three during the follow-up period), and prognostic factors for death. Two hundred eighty-eight consecutive COPD patients admitted to respiratory medicine wards in four(More)
Neurotrophins (NTs) promote survival and differentiation of central and peripheral neurons, and display several activities also in non-neuronal cells. Human lungs synthesize and release NTs, which are probably involved in the pathophysiology of pulmonary disturbances. In this article the expression and anatomic localization of nerve growth factor,(More)
In murine fibroblasts activation of the Shc/Grb-2 pathway by the ErbB-2 kinase involves tyrosine phosphorylation of Shc products and the formation of Shc/ErbB-2, Shc/Grb-2 and Grb-2/ErbB-2 complexes. Tyr 1139 of ErbB-2 bound to the Grb-2 SH2 domain in vitro as well as in intact cells. Tyr 1221 and 1248 are binding sites of gp185ErbB-2 for Shc SH2 domain in(More)
OBJECTIVE Recurrent pleural effusion is a common condition and often presents a challenge for treatment. The aim of this report is to evaluate the long-term follow-up of thoracoscopic management of malignant recurrent pleural effusions. METHODS From July 1st, 1992 to February 28th, 2001, out of 2311 VATS procedures performed at our Institution, 690(More)
OBJECTIVE Some concern still exists regarding long-term lung function following videothoracoscopic talc poudrage for primary spontaneous pneumothorax (PSP). We evaluated lung function at 5 years in a series of 100 patients surgically treated for PSP. METHODS Out of 1065 patients treated for PSP by means of videothoracoscopic talc poudrage from September(More)
BACKGROUND CpG island hypermethylation of gene promoters and regulatory regions is a well-known mechanism of epigenetic silencing of tumor suppressors and is directly linked to carcinogenesis. Wilm's tumor gene (WT1) is a tumor suppressor protein involved in the regulation of human cell growth and differentiation and a modulator of oncogenic K Ras signaling(More)
Neurotrophins are growth factors acting on responsive cells through membrane receptors identified as Trk tyrosine kinase proteins (A, B and C). Trks are present in the mammalian lymphoid organs, and indirect evidence suggests that they are also present in the avian bursa of Fabricius. This study was designed to analyze (a) the occurrence and localization of(More)
BACKGROUND AND AIM OF THE WORK Carbohydrate antigen CA 15-3 is a glycoprotein whose expression, aberrant intracellular localization and changes in glycosylation have been associated with a wide range of cancers. Pulmonary fibrosis represents the final evolution of a chronic inflammation and is defined by the overgrowth of fibroblasts and exaggerated(More)
