TL;DR: This study found that erythropoietin (EPO) induced tyrosine phosphorylation of Akt in a time- and dose-dependent manner in EPO-dependent human leukemia cell line UT-7/EPO, and suggested that the PI3K-Akt activation pathway plays some role in the antiapoptotic effect of EPO.
Journal ArticleDOI
Rituximab plus 70% cyclophosphamide, doxorubicin, vincristine and prednisone for Japanese patients with diffuse large B-cell lymphoma aged 70 years and older.

TL;DR: Three-year PFS with R-70%CHOP for patients aged 70 years and older was not significantly worse than that with full-dose R-CHop for younger patients, suggesting that R- 70% CHOP might be a reasonable choice for patients with DLBCL aged 70 year and older, especially for those with comorbidities.
Journal ArticleDOI
Retropharyngeal Abscess due to Methicillin-resistant Staphylococcus aureus in a Case of Acute Myeloid Leukemia
TL;DR: A case of acute myeloid leukemia (AML) complicated with retropharyngeal abscess (RPA) due to methicillin-resistant Staphylococcus aureus (MRSA) in a 56-year-old man is described.
Journal Article

TL;DR: This case suggests that excess iron hampers hematopoiesis and that adequate iron chelation may improve hematological data in some iron-overloaded patients.
Journal ArticleDOI
Peripherally inserted central catheter-related bloodstream infection due to Tsukamurella pulmonis: a case report and literature review.
TL;DR: PICCs can be associated with T. pulmonis bacteremia, and fourth generation cephalosporins may be effective treatment in this case of a 48-year-old man with acquired immunodeficiency syndrome and diffuse large B cell lymphoma.
