5 months. The main causes Of death were cerebrospinal fluid dissemination as well Lis local recurrence.
Our modified BNCT protocol showed favorable results of patients with NDGB not only for those with good prognoses but also for those with poor prognoses.”
“Background: Atrial fibrillation (AF) is a common cardiac arrhythmia see more characterized by disorganized cardiac electrical activity. Defibrillation electrode placement has been shown to affect the amount of energy and number of shocks required to defibrillate. The objective of this study was to investigate the relationship between esophageal electric fields (EEFs) and atrial defibrillation thresholds (ADFTs) to determine the feasibility of using EEFs during a low-strength shock to predict patient-specific defibrillation electrode placements.
Methods: AF was induced and defibrillated according to a Bayesian four-shock protocol for 12-electrode placements in six pigs. EEFs were measured during each of the four shocks of the protocol and during a 1-J shock for each electrode placement. Squared EEFs (EEF2s) during all shocks were compared to the ADFTs using a linear regression.
Results: There was a negative relationship between EEF2s during the 1-J shocks and ADFTs, with median
R2 values of 0.863 and 0.840 for anterior-anterior (AA) and anterior-posterior (AP) electrode placements, respectively. There was a strong, positive relationship between applied energy and EEF2s, with median R2 values of at least 0.866 for all animals. The placement with the highest EEF2 resulted in the lowest ADFT for both AA and AP placements in four of six pigs. In the other two animals, FK228 cost this held for one electrode set but not both.
Conclusions: There was a strong negative relationship between EEF2s during 1-J shocks and ADFTs for both AA and AP electrode placements. These preliminary results suggest that using EEF2s to predict patient-specific electrode placements is feasible. (PACE 2012; 35: 335-340)”
“Atomistic
simulations are performed to study the structure and geometrical limit of nanoscale twins in NiTi shape memory alloys. We analyze compound twins as narrow as similar to 1 nm, involving a few atomic layers. Baf-A1 mw A novel nanotwinned structure is found, forming through the martensitic transformation of sublattices. We predict the temperatures of phase transformation, which are consistent with experimental measurements. The results provide an atomistic basis for further study of nanometer length scale effects on the martensitic phase transformation and shape memory behavior. (C) 2011 American Institute of Physics.
