09, 0.20). A similar analysis between a type 1 endplate and the presence of a disk herniation (PPV, 0.26; 95% CI: 0.19, 0.34) and between a type 1 endplate and vertebral body spondylolisthesis (PPV, 0.28; 95% CI: 0.20, 0.35) were significant.
Conclusion: Type 1 signal intensity changes on MR images have a high positive predictive value in the identification of a pain generator. (c) RSNA, 2009″
“Metal/insulator/metal thin film stacks showing stable resistive switching are promising candidates for future use as a nonvolatile resistive random access memory, competitive to FLASH and DRAM. Although the switching mechanisms are not completely understood a lot
of theories GW3965 solubility dmso and models try to describe the effects. One of them postulates the trapping and detrapping of electronic charge in immobile traps as the reason for the resistance changes, also known as Simmons & Verderber model. This contribution shows that this “”pure electronic”" switching mechanism will face a voltage-time dilemma-general to all switching insulators-at conditions competitive to the state-of-the-art FLASH. There is an incompatibility
between the long retention time (10 years) and Smoothened Agonist in vivo the short READ/WRITE current pulses (t(READ/WRITE) <= 100 ns) at high densities (area <= 100 x 100 nm(2)) at low applied voltages (<= 1 V). This general dilemma is exemplified in two detailed scenarios with different electronic band and defect properties. (C) 2010 American Institute of Physics. [doi: 10.1063/1.3319591]“
“BACKGROUND: Pulmonary hypertension may occur in patients with interstitial pneumonia and is associated with increased mortality. We sought to determine the prevalence of pulmonary hypertension in
sub-groups of patients with interstitial pneumonia and to investigate possible associations between pulmonary vascular hemodynamics and pulmonary function.
METHODS: The presence or absence of pulmonary hypertension was assessed in 70 patients with advanced interstitial pneumonia who underwent right heart catheterization. The associations of pulmonary hypertension with clinical characteristics and pulmonary function tests were analyzed.
RESULTS: The prevalence of pulmonary hypertension check details in patients with idiopathic interstitial pneumonia was 29% vs 64% in patients with connective tissue disease-interstitial pneumonia (p = 0.013). African American patients had a significantly higher prevalence of pulmonary hypertension in the entire study population (81% vs 22%, p < 0.001) and in the idiopathic interstitial pneumonia group (70% vs 19%, p < 0.01). Regression analyses revealed no association between mean pulmonary artery pressure (mPAP) and forced vital capacity or mPAP and diffusion capacity of the lung for carbon monoxide in the entire cohort or in sub-groups of patients.
CONCLUSIONS: African American patients and patients with connective tissue disease-interstitial pneumonia had a high prevalence of pulmonary hypertension.
