Proteomic analysis reveals a potential role for extracellular vesicles within the erythroblastic island niche.

Erythroblastic island (EBI) macrophages play an essential role in the production and maturation of the vast numbers of red blood cells (RBCs) that are produced throughout life. Their location within the bone marrow makes it difficult to study the cellular and molecular interactions associated with their action so we have used an model of the EBI niche using macrophages derived from human induced pluripotent stem cells (hiPSCs). We previously demonstrated that the activation of the transcription factor KLF1 enhanced the activity of hiPSC-derived EBI macrophages.

Reproducible immortalization of erythroblasts from multiple stem cell sources provides approach for sustainable RBC therapeutics.

Developing robust methodology for the sustainable production of red blood cells is essential for providing an alternative source of clinical-quality blood, particularly for individuals with rare blood group phenotypes. Immortalized erythroid progenitor cell lines are the most promising emergent technology for achieving this goal. We previously created the erythroid cell line BEL-A from bone marrow CD34 cells that had improved differentiation and enucleation potential compared to other lines reported.

Lethal trap trees: a potential option for emerald ash borer (Agrilus planipennis Fairmaire) management.

Background: Economic and ecological impacts of ash (Fraxinus spp.) mortality resulting from emerald ash borer (EAB) (Agrilus planipennis Fairmaire) invasion are severe in forested, residential and urban areas. Management options include girdling ash trees to attract ovipositing adult beetles and then destroying infested trees before larvae develop or protecting ash with a highly effective, systemic emamectin benzoate insecticide.

Efficacy of imidacloprid, trunk-injected into Acer platanoides, for control of adult Asian longhorned beetles (Coleoptera: Cerambycidae).

Feeding experiments with Asian longhorned beetles (Anoplophora glabripennis (Motschulsky)) in a quarantine laboratory were used to assess the effectiveness of imidacloprid in reducing adult fecundity and survival. The beetles were fed twigs and leaves cut between June-September 2010 from Norway maples (Acer platanoides L.) in the beetle-infested area of Worcester, MA.

Health insurance sources for nonelderly patient visits to physician offices, hospital outpatient departments, and emergency departments in the United States.

The authors used data from nationally representative surveys to estimate health insurance sources for non-elderly patient visits to U.S. physicians.
