Lowering the Medicare eligibility age to 62 would result in near universal health care coverage among 62 to 64 year olds. People who purchase individual insurance in the market as well as the uninsured could benefit from Medicare coverage. The change would reduce employer costs for retiree health benefits and lower both retiree and employer costs for COBRA continuation coverage. Lowering the au...

Electron capture times in a separate confinement quantum well (QW) structure with finite electron density are calculated for electron-electron (e-e) and electron-polar optic phonon (e-pop) scattering. We find that the capture time oscillates as function of the QW width for both processes with the same period, but with very different amplitudes. For an electron density of 10cm the e-e capture ti...

Although the aerobactin-mediated iron uptake system has been characterized genetically in Escherichia coli, the siderophore aerobactin was chemically characterized after purification from culture supernatants of Aerobacter aerogenes 62-1, a member of the Klebsielleae. We have cloned and mapped the genes encoding the aerobactin system genes of A. aerogenes 62-1 and begun characterization of the ...

A prospective study was conducted from June 2001 to May 2002 at the Burns Unit of Hospital Regional da Asa Norte, Brasília, Brazil. During the period of the study, 252 patients were treated at the Burns Unit, 49 (19.4%) developed clinically and microbiologically proven sepsis. Twenty-six (53.1%) were males and 23 (46.9%) females with a mean age of 22 years (range one to 89 years) and mean burne...

CD23 is a transmembrane protein expressed on the surface of B-lymphocytes that binds IgE, CD21, CD11b, and CD11c. High concentrations of soluble CD23 and L-selectin are found in the serum of patients with B-chronic lymphocytic leukemia (B-CLL). Because extracellular adenosine triphosphate (ATP) causes shedding of L-selectin via activation of P2Z/P2X7 receptors expressed on B-CLL lymphocytes, we...
