DISEASE OVERVIEW: The eosinophilias encompass a broad range of nonhematologic (secondary or reactive) and hematologic (primary, clonal) disorders with potential for end-organ damage. DIAGNOSIS: Hypereosinophilia has generally been defined as a peripheral blood eosinophil count greater than 1500/mm(3) and may be associated with tissue damage. After exclusion of secondary causes of eosinophilia, diagnostic evaluation of primary eosinophilias relies on a combination of morphologic review of the blood and marrow, standard cytogenetics, fluorescent in situ-hybridization, flow immunocytometry, and T-cell clonality assessment to detect histopathologic or clonal evidence for an acute or chronic myeloid or lymphoproliferative disorder...

BACKGROUND/AIMS: The Polo-like kinase 1 (Plk1) inhibitor volasertib is used in the treatment of malignancy. Volasertib is partially effective by triggering suicidal death or apoptosis of tumor cells. Similar to apoptosis of nucleated cells, erythrocytes may enter suicidal cell death or eryptosis, which is characterized by cell membrane scrambling with phosphatidylserine translocation to the cell surface and by cell shrinkage. Stimulators of eryptosis include energy depletion, hyperosmotic shock, oxidative stress and excessive increase of cytosolic Ca2+ activity ([Ca2+]i)...

Multiple myeloma (MM), a malignancy of the bone marrow, is characterized by a pathological increase in antibody-producing plasma cells and an increase in immunoglobulins (plasmacytosis). In recent years, bone morphogenetic proteins (BMPs) have been reported to be activators of apoptotic cell death in neoplastic B cells in MM. Here, we use bone morphogenetic protein 2 (BMP2) to show that the "apoptotic" effect of BMPs on human neoplastic B cells is dominated by anti-proliferative activities and cell cycle arrest and is apoptosis-independent...

Multiple myeloma (MM) is a plasma B-cell hematologic cancer that causes significant skeletal morbidity. Despite improvements in survival, heterogeneity in response remains a major challenge in MM. Cluster of differentiation 38 (CD38) is a type II transmembrane glycoprotein over-expressed in myeloma cells and is implicated in MM cell signaling. Daratumumab is US Food and Drug Administration approved high-affinity monoclonal antibody targeting CD38 that is clinically benefiting refractory MM patients. Here, we evaluated [(89)Zr]Zr-DFO-daratumumab positron emission tomography/computed tomography (PET/CT) imaging in MM tumor models...

Recombinant human bone morphogenetic protein (BMP)-2 is an FDA-approved therapy for nonunion tibia fracture, though it has a number of biological and practical disadvantages. Our research group has developed a novel tissue engineering strategy termed antibody-mediated osseous regeneration. This entails application of anti-BMP-2 monoclonal antibodies (mAbs) to capture endogenous BMP's to mediate in vivo bone formation. This has been documented in a number of animal models. The present exploratory study sought to investigate the application of antibody-mediated osseous regeneration for repair of nonunion tibia defect in a nonhuman primate model...

The mechanisms of action potential (AP) generation in the myoepithelial cells of the Tunicata heart are not yet well understood. Here, an attempt was made to elucidate these mechanisms by analyzing the effects of specific blockers of K(+), Na(+) and Ca(2+) currents on the configuration of transmembrane APs and their frequency in the spontaneously beating ascidian heart. In addition, an immunocytochemical analysis of heart myoepithelial cells was performed. Staining with anti-FMRF-amide and anti-tubulin antibodies did not reveal any nerve elements within the heart tube...

NHL is the most common hematologic cancer in adults. Rituximab is the FDA approved treatment of relapsed or refractory low grade B-cell Non-Hodgkin Lymphoma (NHL). But patients eventually become resistant to rituximab. Since lymphocytes and lymphoma cells are highly radiosensitive, low grade NHL that has relapsed or refractory to standard therapy is treated by RIT in which a beta-emitting radionuclide coupled to anti-CD20 antibody. The association of beta emitter radionuclide to rituximab enhances its therapeutic efficacy...

The long-term outcome of multiple myeloma (MM) has been greatly improved by the advent of new agents such as proteasome inhibitors (PIs) and immunomodulatory drugs (IMiDs), despite the disease remaining mostly incurable. Treatment design is the critical determinant for the survival period and for the quality and way of life in patients with relapsed/refractory MM (RRMM). Recently, the choice of therapeutic options for RRMM has been expanded by the introduction of second generation PIs such as carfilzomib and ixazomib, and therapeutic monoclonal antibodies such as elotuzumab and daratumumab...

The current gold standard treatment for peripheral nerve injury is nerve grafting but this has disadvantages such as donor site morbidity. New techniques focus on replacing these grafts with nerve conduits enhanced with growth factors and/or various cell types such as mesenchymal stem cells (MSCs). Dental-MSCs (D-MSCs) including stem cells obtained from apical papilla (SCAP), dental pulp stem cells (DPSC), and periodontal ligament stem cells (PDLSC) are potential sources of MSCs for nerve repair. Here we present the characterization of various D-MSCs from the same human donors for peripheral nerve regeneration...
