1%%). Survival of our patients

was less than in developed countries and cardiac complications were the most common cause of mortality and morbidity in these patients. Regarding the key role of iron chelation in prevention of different complications in BTM, correction of iron chelation regimen should be well considered.</.”
“This study aimed Selleck Dibutyryl-cAMP to find out the primary factors influencing the diameter of electrospun nanofibers of nylon-6,6 using artificial neural networks (ANNs). Four variables, namely, polymer concentration, working distance, injection rate, and applied voltage were considered as input parameters and the nanofibers diameter measured by scanning electron microscopy was taken as the output. The data were modeled and validated against a set of unseen data. The generated model was used to study the interactions occurring between the

input variables and their effect on the diameter. Results show that the injection rate and the polymer concentration are major factors affecting the nanofibers diameter with inverse and direct relations with the diameter, respectively, while the working distance and the applied voltage have direct but minor effects on nanofibers diameter.

“In this work, bubble polarization domains in periodically ordered ferroelectric Pb(Zr(0.4)Ti(0.6))O(3) nanodot arrays and their formation mechanisms have been investigated by piezoresponse force microscopy (PFM) and Monte-Carlo simulations. The PFM observations reveal the coexistence of single domain and apparent bubble domain patterns within the same nanodot array, which also exhibit dissimilar polarization reversal processes. The formation of various polarization configurations can be accounted for by the interplay of various factors, such as polarization anisotropy and depolarization field. Using Monte-Carlo simulation, we are able to reproduce bubble and single domains and further predict that these patterns can be tailored by varying the

nanodot parameters, including dot height, aspect ratio, etc. (C) 2011 American Institute of Physics. [doi:10.1063/1.3623766]“
“Background: The increased frequency of laparoscopic learn more hepatic resection as a principal or adjunct component of patient care has driven the need for and development of efficient and safe hepatic parenchymal transection technologies. At present, various devices are available for pre-coagulation transection (PCT) of hepatic parenchyma with the intent of minimizing procedure-associated postoperative haemorrhage and bile leak. This report presents the evaluation of a novel bipolar radiofrequency (RF) energy device for PCT used for laparoscopic hepatic resection.

Methods: Patients undergoing laparoscopic hepatic resection using the Enseal (TM) device (SurgRx Inc.) were identified from the prospectively maintained hepatobiliary database.
