Corneal explantation activity in 2002: an analysis of the modified operational schedule.

After data have been gathered about corneal explants performed within the AOP health-care web throughout 2001, the resulting findings were used to update the selection system for donation fitness and operational procedures. The rejection of anti-HBc-positive grafts and tissues coming from subjects more than 79 years old resulted in decreased donations (256 donations, that is 492 corneal explants in 2001 vs 140, that is 273 in 2002), although the number of deaths was unchanged (1298 in 2001 vs 1294 in 2002). Corneas fit for transplantation did not change in number-126 (25.

Summary: the quality improvement program in organ donation of the Tuscany region.

Since October 2002, after a pilot period, a quality improvement program in organ donation has been underway in Tuscany. This program is based on a database elaborated by the Transplant Coordination Office of the Pisa University, according to the Spanish program of the National Transplant Organization. All encephalic deaths occurring in intensive care units beds during mechanical ventilation are registered in the database.

Lyn kinase is activated following thrombopoietin stimulation of the megakaryocytic cell line B1647.

Background And Objectives: B1647 is a cell line derived from bone marrow cells of a patient with acute myeloid leukemia (M2) with a complete erythro-megakaryocytic phenotype and bears both k and p isoforms of c-mpl. Interestingly, spontaneous B1647 cell proliferation is significantly potentiated by thrombopoietin (TPO).

Design And Methods: We aimed to evaluate the proliferative signal transduction events following the activation of c-mpl and we stimulated B1647 cells with TPO 40 ng/mL for 3, 7, 15 and 30 minutes; cells were then lysed and whole lysates were immunoprecipitated with anti-phosphotyrosine antibodies.

Treatment of large cell lymphoma in elderly patients with a mitoxantrone, cyclophosphamide, etoposide, and prednisone regimen: long-term follow-up results.

Background: Patients with aggressive non-Hodgkin lymphoma (NHL) require intensive and extensive therapy, which seems impracticable in elderly patients due to hematologic and extrahematologic toxicity. Consequent dose reduction and therapy attenuation can reduce treatment-related toxicity but also decreases therapeutic efficacy. Thus, age represents a fundamental prognostic factor that has a profound influence on both therapeutic decisions and patient outcome.
