The most common chronic symptom was chest pain, with one child also reporting dyspnea and tachycardia.”
“We suggest a wavelength-dependent figure of merit for transparent conducting nanotube networks, composed

VX-765 of the sheet resistance and the optical density. We argue that this would be more useful than other suggestions prevailing in the literature because it relies on more realistic assumptions regarding the optical parameters of real nanotubes: it takes into account the fact that the dc resistivity depends on the concentration of free carriers, while the visible absorption is caused by bound carriers. Based on sheet resistance measurements and wide-range transmission spectra, we compare several commercial nanotube types and find correlation between metal enrichment and figure of merit. A simple graphical approach is suggested to determine if the required optical and transport properties can be achieved by varying the thickness of the nanotube layer or a more aggressive treatment is needed. The procedure can be extended to oxide coatings as well. (C) 2010 American Institute

“BACKGROUND Some patients continue to have significant heart failure symptoms despite optimal medical therapy

METHODS We describe a first in-human experience with an implantable non blood-contacting extra ascending aortic counterpulsation heart assist system (C-Pulse) in 5 end-stage heart failure patients, aged 54 to 73 years

RESULTS All patients improved by 1 NYHA class and improvements

BAY 1895344 in vivo in invasive hemodynamics were documented in 3 patients Three AZD4547 of 5 patients (60%) had infectious complications Two patients were explanted at 5 and 7 weeks, respectively, as a result of mediastinal infection related to the implant procedure One patient was successfully transplanted at 1 month and 1 remained hemodynamically improved on the device at 6 months but suffered infective complications The device and protocol have been modified as a result of this pilot study with a further multicenter safety study underway

CONCLUSIONS Although feasibility of this device is suggested by this pilot study, safety and efficacy will need to be examined in a larger cohort with longer follow-up J Heart Lung Transplant 2010 29 1427-32 (C) 2010 International Society for Heart and Lung Transplantation All rights reserved”
“Increasing evidence suggests that the recently identified human bocavirus (hBoV) is a cause of acute respiratory illness. However, the duration of hBoV shedding from the respiratory tract as demonstrated by positive hBoV polymerase chain reaction is unclear. We describe the virologic and clinical characteristics of 6 immunocompetent children with hBoV persistence in the respiratory tract for up to 4.5 months.
