Extracellular Matrix Molecular Remodeling in Human Liver Fibrosis Evolution.

Chronic liver damage leads to pathological accumulation of ECM proteins (liver fibrosis). Comprehensive characterization of the human ECM molecular composition is essential for gaining insights into the mechanisms of liver disease. To date, studies of ECM remodeling in human liver diseases have been hampered by the unavailability of purified ECM.

Fine needle aspiration cytology determinants of the diagnosis of primary nodal Kaposi's sarcoma as the first sign of unknown HIV infection: a case report.

Background: Kaposi's sarcoma (KS) is a vascular malignant tumor characterized by human herpesvirus 8 infection of neoplastic cells. Diffuse cutaneous lesions represent the classical clinical presentation. This case report describes the first fine needle aspiration cytology findings of a primary lymph nodal KS, a rather unusual localization of the disease.

Human nasal rhinosporidiosis: an Italian case report.

Background: Rhinosporidiosis is a disease affecting primarily the mucosa of nose, conjunctiva and urethra. It is endemic in some Asiatic regions, affecting people of any age and sex. Its manifestation is a polypoid mass growing inside the affected cavity and the only treatment is surgical excision.

Fatty acid synthase (FAS) is a marker of increased risk of recurrence in lung carcinoma.

Background: We explored the expression of Fatty Acid Synthase (FAS) in lung carcinomas and its association with clinico-pathological features and prognosis. FAS is a recently discovered molecule involved in the energy supply of normal cells. FAS is also overexpressed in neoplastic tissues because of their increased necessity for energy.
