MAIN OUTCOMES AND MEASURES Adherence to pediatric asthma controller medication, measured as the medication possession ratio over 24 months. RESULTS In the intention-to-treat analysis, inhaled corticosteroid adherence

was 25.4% higher in the intervention group than in the usual care group (24-month mean [SE] adherence, 44.5%[1.2%] vs 35.5%[1.1%], respectively; P smaller than .001). Asthma-related urgent care events did not differ between the 2 groups. The intervention effect was consistent in subgroups stratified by age, sex, race/ethnicity, body mass index, and disease-related characteristics. CONCLUSIONS AND RELEVANCE The intervention’s significant impact on adherence demonstrates strong potential for low-cost SR adherence programs integrated with an Selleck Compound C electronic health record. The absence of change in urgent learn more care visits may be attributable to the already low number of asthma urgent care visits within Kaiser Permanente Colorado. Application of electronic health record-leveraged SR interventions may reduce health care utilization when applied in a population with less-controlled asthma.”
“The mechanisms that regulate the pruning of mammalian axons

are just now being elucidated. Here, we describe a mechanism by which, during developmental sympathetic axon competition, winning axons secrete brain-derived neurotrophic factor (BDNF) in an activity-dependent fashion, which binds to the p75 neurotrophin receptor (p75NTR) on losing axons www.selleckchem.com/products/ldk378.html to cause their degeneration and, ultimately, axon pruning. Specifically, we found that pruning of rat and mouse sympathetic axons that project to the eye requires both activity-dependent BDNF and p75NTR. p75NTR and BDNF are also essential for activity-dependent axon pruning in culture, where they mediate pruning by directly causing axon degeneration. p75NTR, which is enriched in losing axons, causes

axonal degeneration by suppressing TrkA-mediated signaling that is essential for axonal maintenance. These data provide a mechanism that explains how active axons can eliminate less-active, competing axons during developmental pruning by directly promoting p75NTR-mediated axonal degeneration.”
“The rhodium-catalyzed intramolecular carboacylation of quinolinyl ketones serves as an ideal subject for the mechanistic study of carbon-carbon bond activation. Combined kinetic and NMR studies of this reaction allowed the identification of the catalytic resting state and determination of the rate law, (12)C/(13)C kinetic isotope effects, and activation parameters. These results have identified the activation of a ketone-arene carbon-carbon single bond as the turnover-limiting step of catalysis and provided quantitative detail into this process.”
