The results showed homogenization pressure and number
of homogenization passes had an obvious influence on the mean particle size and the size distribution. The SPI suspension homogenized at 207 MPa from 0 to 30 passes exhibited a shear-thinning behavior, which was accompanied by the reduction of mean particle size from 3331.3 to 135.8 nm. narrower particle size distributions, and increased absolute zeta potentials. Small particle sizes not only improved mechanical and transparent properties, but also reduced water absorption properties for SPI films. However, the reduction AZD0156 in vivo of particle size showed little impact on the thermal properties of SPI films. These findings may help better utilization of SPI in the development of novel
SPI-based films. (C) 2012 Elsevier B.V. All rights reserved.”
“Objective: To determine the prevalence of trial registration in randomized controlled trials (RCTs) published in 2010 (PUBMED/LILACS) from Latin America and the Caribbean’s (LAC) and to compare methodological characteristics between registered and nonregistered RCTs.
Study Design and Setting: A search for detecting RCTs in which at least the first/contact Selleckchem Crenigacestat author had a LAC’s affiliation was made. We determined if RCTs were registered in the International Clinical Trial Registry Platform (ICTRP). Data were independently extracted by two authors. The risk of bias (RoB) was assessed in all registered RCTs (n = 89) and in a sample of nonregistered RCTs (n = 237).
Results: The search identified 1,695 references; 526 RCTs from 19 countries were included. 16.9% (89/526) of RCTs were registered in the ICTRP; however, only 21 (4.0%) were prospectively registered. A significant difference was found in the overall assessment of the RoB between registered and nonregistered RCTs. Overall, registered RCTs were multinational, had larger sample size and longer follow-up, and reported more
frequently information Epigenetics inhibitor on funding, conflict of interests, and ethic issues. No significant differences were found when analyzing prospectively registered RCTs.
Conclusion: This study shows that trial registration rates are still low in LAC and the quality of reporting needs to be improved. (c) 2012 Elsevier Inc. All rights reserved.”
“Sebaceoma is a benign sebaceous neoplasm, which has been reported to show characteristic growth patterns, such as, ripple, labyrinthine/sinusoidal, and carcinoid-like patterns. Another recent finding regarding in sebaceoma is the observation of apocrine differentiation within the sebaceoma lesion. This report describes a case of carcinoid (a partial ripple and labyrinthine) pattern sebaceoma with apocrine differentiation with a literature review and immunohistochemical studies.
