The no-touch time varied from 2 min up to 10 min; then 30 min of CPR were performed. Brain death was determined by established clinical and electrophysiological criteria. In all animals with cardiac arrest of at least 6 min, a persistent loss of brainstem reflexes and no reappearance of bioelectric

brain activity occurred. Reappearance of EEG activity was found until 4.5 min of cardiac arrest and subsequent CPR. Brainstem reflexes were detectable until 5 min of cardiac arrest and subsequent CPR. According to our experiments, the suggestion of 10 min of cardiac find protocol arrest being equivalent to brain death exceeds the minimum time after which clinical and electrophysiological criteria of brain death are fulfilled. Therefore shorter no-touch times might be

ethically acceptable to reduce warm ischemia time.”
“The titanium tantalum oxide, TiTaO, was fully characterized in situ Crenigacestat in vivo in an integrated metal-insulator-metal (MIM) configuration on a wide frequency band, from 1 mHz to 30 GHz. First, XPS and XRD analysis show that TiTaO dielectric is amorphous and presents Ti-O, Ta-O, and Ti-Ta bounds. Next, by using dedicated MIM test devices and a specific extraction procedure, both relative permittivity kappa and loss tangent tan delta were extracted on the wide frequency band. The results show a dependence on both frequency and thickness. Conduction mechanism of ion impurities such as oxygen vacancies at very low frequencies (below 0.1 Hz), Maxwell-Wagner relaxations due to space charges at electrode interface (between 0.1 and 5 Hz), and dielectric grain boundaries or hopping (between 1 and 100 MHz) are underlined and studied with temperature measurements. The paper shows the usefulness of in situ wideband frequency

measurements and that the dielectric permittivity of TiTaO in a 100 nm thick film is decreasing from 86 at 10 kHz to 20 at 10 GHz. (C) 2011 American Institute of Physics. [doi:10.1063/1.3626067]“
“Renal allograft compartment syndrome is an under recognized cause of early R406 Angiogenesis inhibitor allograft dysfunction which can be reversed by early intervention. It occurs early after renal transplantation where closure of the anterior abdominal wall seems to compress the transplant in the limited retroperitoneal space. The literature about this syndrome in renal transplantation is sparse. Our report describes the diagnostic criteria and the management of two renal transplant recipients with this syndrome. Its diagnosis depends upon duplex vascular scan findings of reversed or absent diastolic flow in the renal vasculature in the absence of any perigraft collection or severe acute tubular necrosis. In our hands emergency laparotomy, decompression of the transplant and closure with interposition mesh salvaged these kidneys.”
