A homologue of the Drosophila homothorax (hth) gene, Xenopus Meis3 (XMeis3), was cloned from Xenopus laevis. XMeis3 is expressed in a single stripe of cells in the early neural plate stage. By late neurula, the gene is expressed predominantly in rhombomeres two, three and four, and in the anterior spinal cord. Ectopic expression of RNA encoding XMeis3(More)
Divergent views remain regarding the safety of treating anemia with red blood cell (RBC) transfusion in patients with acute coronary syndrome (ACS). We used a prospective database to study effect of RBC transfusion in patients with acute myocardial infarction (MI; n = 2,358). Cox regression models were used to determine the association between RBC(More)
Neural crest induction is thought to occur by a two-step process. Axially fated mesoderm induces neural plate, which is then recruited to neural crest by nonneural epidermal ectoderm at the neural plate border. This model suggests a rather indirect role for mesoderm in inducing neural crest. We extensively examined the role of mesoderm in neural crest(More)
Acute infusion reactions are the most common documented adverse reactions reported with rituximab, with overt cytokine release syndrome, and hematological adverse events being much rarer. The clinical course of a patient with mantle cell lymphoma, who developed acute thrombocytopenia and leukopenia following rituximab administration, is described and the(More)
INTRODUCTION The role of granulocyte transfusions (GT) in patients with neutropenia-related infections remains controversial. MATERIALS AND METHODS A retrospective analysis of 47 neutropenic patients, treated with 348 consecutive GTs for life-threatening infections between 1999 and 2004, is presented. RESULTS The only grade III-IV toxicity observed in(More)
Terrorist attacks in crowded places cause multiple casualties that are evacuated by quick succession to nearby hospitals. The study goals were to analyse the issues of patient misidentification and excessive blood request and to develop recommendations for the management of such episodes. A retrospective analysis of nine explosion attacks was performed. In(More)
Plasmapheresis (PA) and low-density lipoprotein apheresis (LDL-A) were assessed in five children with homozygous familial hypercholesterolemia (HFH) previously receiving statins. LDL-A required smaller extracorporeal blood volumes. Mean HDL-cholesterol reduction post-procedure was 32% and 60% with LDL-A and PA, respectively. Non-HDL-C reduction was 64% and(More)
In July 2006 a Hizballah attack erupted at the Lebanon-Israel border. Reported here is the experience of the Rambam Health Care Campus--a level I trauma center--during 33 days of warfare. Two hundred ninety-five soldiers and 209 civilians were admitted to the emergency department (ED). Forty-eight wounded soldiers (16%) and 12 civilians (6%) had(More)
Loxoscelism, characterized by high fever, vomiting, malaise, a dermonecrotic lesion, and thrombocytopenia, was diagnosed in a 3-year-old female. Clinical laboratory and dermatological signs are described. Blood test showed a transient hypercoagulable state and the presence of IgG antibodies against platelets, suggesting an immune-mediated mechanism for(More)
