Data were analyzed with SPSS software.
Results:
One hundred fifty-six Videos were included in the analysis. Forty videos were classified as very or moderately useful (25.6%). Sources of the videos were as follows: patient experience, 103 videos (66%); physician, 30 (19%); surgical technique, 14 (9%); and news report, 9 (6%). Physician sourced information was generally at least moderately useful (58%) and patient experience videos were the predominant source of videos categorized as not useful or misleading (50%). Physician sourced information (coefficient = 0.61; 95% CI: .21 to 1.00,p = 0.003) and PT search term GSK2126458 concentration (coefficient = 0.26; 95% CI: 0.05 to .47, p = 0.017) were the most useful videos after adjusting for mean duration, days learn more online, number of views and page search.
Conclusion: YouTube has a large number of videos on pediatric tonsillectomy with a variety of content ranging from very useful to not useful, and misleading. Health care professionals must recognize the potential influence that these video Web sites may have on patient attitudes. (C) 2013 Elsevier Ireland Ltd. All rights reserved.”
“Glycerol dehydratase (GDHt) is the rate limiting enzyme in the biosynthesis of 1,3-propanediol from glycerol. The optimization of inducting process for recombinant GDHt from Klebsiella pneumoniae XJPD-Li
Carried out to increase specific activity and ratio of soluble form. The optimum Condition was inducing under the isopropyl-beta-D-thiogalactoside Concentration of 0.8 mM and the temperature of 20 degrees C for 3 h. Homogeneity of
GDHt then was obtained by affinity Chromatography, resulted in 2.11-fold purification and an overall yield of 47.5%. The optimum pH and reaction temperature of GDHt were pH 8.0 and 45 degrees C, respectively. The K(m) for glycerol, 1,2-propanediol, 1,2-ethanediol and Coenzyme B(12) were 0.48 mM, 1.43 mM, 3.07 mM, and 10.03 nM, respectively. The GDHt showed relatively stable even under temperature of 40 degrees C and a bit blunt to oxygen. The thermo-inactivation kinetic models were fit linear under different temperatures.”
“Background: In the past decade, there has been a trend toward open reduction and internal fixation of unstable distal radial PXD101 Epigenetics inhibitor fractures. There are now more than thirty different implant designs specific for the fixation of distal radial fractures. A multicenter prospective study of a case series was conducted to determine the efficacy of the operative management of distal radial fractures stabilized with 2.4-mm locking plates.
Methods: One hundred and fifty patients were entered into the study over a two-year period. The mean age of these patients was fifty-one years, and the cohort included eighty-eight women and sixty-two men. Eighty-six patients sustained a low-energy injury. Seventy-one percent of the fractures in the series were intra-articular and were Type C according to the Muller-AO Comprehensive Classification.
