With the increase in the particles size, H(EB) decreases monotono

With the increase in the particles size, H(EB) decreases monotonously. Furthermore, vertical magnetization shift was also observed for the small particles. Exchange bias is attributed to the exchange coupling interactions between ferromagnetic and spin-glass-like (or antiferromagnetic) phase interface layers.”
“PURPOSE: To compare the efficacy of epi-Shugarcaine solution (epinephrine 0.025% and lidocaine 0.75% in fortified balanced salt solution [BSS Plus]) (epi-S) and Lundberg and Behndig’s intracameral dilation solution (cyclopentolate 0.1%, phenylephrine 1.5%, and lidocaine 1%) (LB) for intracameral dilation

for cataract surgery.

SETTING: Private clinic, Lincolnwood, Illinois, USA.

METHODS: In this paired-eye single-masked prospective study, the first eye scheduled Dorsomorphin in vivo for surgery was randomized selleck compound library to receive LB solution or epi-S solution intracamerally at the time of cataract surgery; the second eye to have surgery received the alternative solution. Each eye received I drop of tropicamide 1% at least 20 minutes before the

start of surgery. Pupil measurements were made before the incision was created, 1 minute after intracameral solution injection, after the anterior chamber was filled with an ophthalmic viscosurgical device, and at the conclusion of the case. Pupil size was objectively graded via software operated by a video technician who was masked to which solution was used.

RESULTS: Eighty-four eyes of 42 patients were enrolled in the study. At each time point after instillation, the pupil was statistically significantly larger with epi-S solution than with LB solution, averaging 0.528 mm larger 1 minute after instillation (mean 7.183 versus 6.665 mm) to 0.34 mm larger (mean 7.381 GSK1120212 concentration versus 7.040 mm) by the end of the case.

CONCLUSION: When combined with 1 drop of tropicamide 1% preoperatively, both formulations provided safe and effective intracameral dilation for cataract

surgery; however, the epi-S solution was the more efficacious at each step of the procedure.”
“Aggressive donor management, including the placement of a pulmonary artery catheter (PAC) to monitor hemodynamic status and tissue perfusion, has been associated with a significant increase in the number of organs recovered for transplantation. Nonetheless, there has been growing scrutiny over the use of PACs because of their known complications and lack of therapeutic effect. The purpose of this study is to evaluate the use of PACs in the management of organ donors. The records of all patients who successfully donated organs between January 1, 2002 and December 31, 2005 were reviewed. A total of 96 patients underwent successful organ donation during the four-yr study period. Of these, 49 (51.0%) were managed with a PAC. Compared with donors managed without a PAC, there were significantly more hearts recovered from donors managed with a PAC (71.4% vs. 44.7%; p = 0.
