The identification of genetic and biochemical mechanisms underlying tumor growth and progression along with the unraveling of human genoma provided a plethora of new targets for cancer detection, treatment and monitoring. Simultaneously, the extraordinary development of a number of imaging technologies, including hybrid systems, allowed the visualization of(More)
T-cell acute lymphoblastic leukemia (T-ALL) and lymphoma (T-LBL) share common morphological and immunophenotypic features and are treated with similar therapeutic approaches. Nonetheless, they show distinct clinical presentations, suggesting that they may represent two different biological entities. To investigate the genetic characteristics of T-LBL and(More)
Multiple lesions in genes that are involved in cell cycle control, proliferation, survival and differentiation underlie T-cell acute lymphoblastic leukaemia (T-ALL). We translated these biological insights into clinical practice to improve diagnostic work-ups and patient management. Combined interphase fluorescence in situ hybridization (CI-FISH), single(More)
In mammals fertility depends on timely onset and cyclic secretion of gonadotropin-releasing hormone (GnRH), secreted by scattered hypothalamic neurons (GnRH neurons). These cells originate in the nasal placode and migrate first in the nasal compartment, then through the cribriform plate and finally across the basal forebrain, before they set in their final(More)
Tumor microenvironment consists of a number of components including host resident stromal cells, infiltrating immune cells and extracellular matrix. The architecture surrounding tumor cells is not static but is subjected to a continuous remodeling in response to the dynamic interplay between tumor and stromal cells and to the production of extracellular(More)
The relationship between hyperlipidaemia and thrombophilic state in atherosclerosis was appraised by evaluation of platelet aggregation according to Breddin in 20 patients with clinically established atherosclerosis, 10 normal controls, and 22 subjects taken from the average population of a medical department aged 12-58 yr with no history of(More)
