“Multiple myeloma (MM) is characterized by uncontrolled proliferation of malignant plasma cells in the bone marrow and peripheral blood. Here, we found that CD40 and CD40L co-expressed on XG1 MM cells and the coordinated expression of CD40-CD40L was critical for production and autocrine IL-6 in XG1 cells. Furthermore, TNF-alpha enhanced the expression of both CD40 and CD40L expression on XG1 cells. We also found that persistent CD40L/CD40 signaling was required for the constitutive activation of

NF-kappa B in the cells.”
“BACKGROUND:\n\nThe optimal hemoglobin (Hb) level in acute myocardial infarction (MI) is unknown. The goal of this study was to determine find more the optimal Hb concentration in acute MI and whether transfusion of fresh blood to correct anemia reduces myocardial injury and improves outcome.\n\nSTUDY DESIGN AND METHODS:\n\nAnemia was induced in rats by an iron-deficient diet and phlebotomy. MI was induced by left coronary artery ligation. Some rats received transfusion of fresh blood. Survival, hemodynamic measurements, and infarct size were determined 24 hours after MI.\n\nRESULTS:\n\nReduction of Hb to 80 to 90 and 70 to 80 g/L decreased 24-hour survival after MI to 42 and 47%, respectively (p < 0.05). Infarct size was increased in both 70 to 80 and 80 to 90 g/L anemic groups compared to the normal Hb group (p < 0.05). Cardiac function was decreased in anemic groups after MI (p < 0.01). Transfusion

of fresh blood to increase Sotrastaurin Hb from 80 to 90 g/L to 100 g/L decreased infarct size (p < 0.05) and improved cardiac function (p < 0.05), and a trend toward better survival (73%) was observed. click here Transfusion from 80 to 90 g/L Hb to 120 g/L Hb was associated with larger infarct size (p < 0.05), decreased cardiac function (p < 0.05), and no improvement in survival (47%, p = NS).\n\nCONCLUSION:\n\nAnemia increases infarct size and decreases cardiac function and survival in acute MI. Transfusion of anemic animals up to 100 g/L Hb with fresh blood reduces infarct size and improves cardiac function.

However, transfusion to 120 g/L Hb did not demonstrate any additional benefit and was associated with larger infarcts.”
“A total of 38 patients (18 female/20 male) with childhood meningioma were recruited from the German registry HIT-Endo (1989-2009). In 5 cases meningioma occurred as second malignant neoplasm (SMN). Histologies were confirmed by reference assessment in all cases (SMN: 2 WHO I, 1 WHO II, 2 WHO III). The SMNs were diagnosed at a median age of 12.4 years with a median latency of 10.2 years after primary malignancy (PMN; 4 brain tumors, 1 lymphoblastic leukemia; median age at diagnosis 2.7 years). Meningioma occurred as SMN in the irradiated field of PMN (range 12-54 Gy). The outcome after treatment of SMN meningioma (surgery/irradiation) was favorable in terms of psychosocial status and functional capacity in 4 of 5 patients (1 death).
