Interestingly, patch-clamp experiments showed that Bioactive Compound Library exposure of guard cells to ABA greatly enhances the ability of cytosolic Ca2+ to activate S-type anion channels and down-regulate inward-rectifying K+ channels, providing strong evidence for a Ca2+ sensitivity priming hypothesis. The present study demonstrates and quantifies an attenuated and slowed ABA response when [Ca2+](i) elevations are directly inhibited in guard cells. A minimal model is discussed, in which ABA enhances (primes) the [Ca2+](i) sensitivity of stomatal closure mechanisms.”
“Purpose: The antineoplastic
agents infusion through peripheral lines may lead to several adverse events such as extravasation that is one of the most severe acute reactions of this sort of treatment. The extravasation prevention and management must be part of a safe and evidence-based nursing care. Due to this fact, two algorithms were developed with the purpose of guiding nursing care to children who undergo chemotherapy through peripheral line. The objectives of this study were to determine the content validity of both algorithms with pediatric oncology nurses in Brazil and United States of America,
and to verify the agreement between the evaluations of both groups.
Methods and Sample: A descriptive validation study was carried out through the Delphi Technique that has the following steps: development of the data collection instrument, application to the specialists, data analysis, algorithms’ review, re-evaluation by Epigenetics inhibitor the specialists, final data analysis and content validity determination.
Results: The data analysis was descriptive and based on the GM6001 clinical trial specialists agreement consensus equal or higher than 80% in every step of the algorithms. The process showed that the agreement with both instruments ranged
from 92.8% to 99.0%.
Conclusion: The algorithms are valid for application in nursing care with the main purpose of preventing and managing the antineoplastic agents’ extravasation. (C) 2011 Elsevier Ltd. All rights reserved.”
“In this research, fully environment-friendly, sustainable and biodegradable composites were fabricated, using wheat straw and rice husk as reinforcements for thermoplastics, as an alternative to wood fibers. Mechanical properties including tensile, flexural, and impact strength properties were examined as a function of the amount of fiber and coupling agent used. In the sample preparation, three levels of fiber loading (30, 40, and 50 wt %) and two levels of coupling agent content (0 and 2 wt %) were used. As the percentage of fiber loading increased, flexural and tensile properties increased significantly. Notched Izod results showed a decrease in strength as the percentage of fiber increases. With addition of 50%, fiber, the impact strengths decreased to 1.6.3, 1.4.4, and 1.6.4 J/m respectively, for wheat straw-, rice husk-, and poplar-filled composites.
