    Reducing the amounts of dissolved substances in surface and ground water is of major concern nationally and within the agricultural community. The primary focus of this study was to investigate the fate of azinphosmethyl (Guthion®) in sugarcane canopy, soil and runoff water.https://digitalcommons.lsu.edu/agcenter_bulletins/1014/thumbnail.jp

    2019 international consensus on cardiopulmonary resuscitation and emergency cardiovascular care science with treatment recommendations : summary from the basic life support; advanced life support; pediatric life support; neonatal life support; education, implementation, and teams; and first aid task forces

    The International Liaison Committee on Resuscitation has initiated a continuous review of new, peer-reviewed, published cardiopulmonary resuscitation science. This is the third annual summary of the International Liaison Committee on Resuscitation International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations. It addresses the most recent published resuscitation evidence reviewed by International Liaison Committee on Resuscitation Task Force science experts. This summary addresses the role of cardiac arrest centers and dispatcher-assisted cardiopulmonary resuscitation, the role of extracorporeal cardiopulmonary resuscitation in adults and children, vasopressors in adults, advanced airway interventions in adults and children, targeted temperature management in children after cardiac arrest, initial oxygen concentration during resuscitation of newborns, and interventions for presyncope by first aid providers. Members from 6 International Liaison Committee on Resuscitation task forces have assessed, discussed, and debated the certainty of the evidence on the basis of the Grading of Recommendations, Assessment, Development, and Evaluation criteria, and their statements include consensus treatment recommendations. Insights into the deliberations of the task forces are provided in the Justification and Evidence to Decision Framework Highlights sections. The task forces also listed priority knowledge gaps for further research

    2017 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations Summary

    The International Liaison Committee on Resuscitation has initiated a near-continuous review of cardiopulmonary resuscitation science that replaces the previous 5-year cyclic batch-and-queue approach process. This is the first of an annual series of International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations summary articles that will include the cardiopulmonary resuscitation science reviewed by the International Liaison Committee on Resuscitation in the previous year. The review this year includes 5 basic life support and 1 paediatric Consensuses on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations. Each of these includes a summary of the science and its quality based on Grading of Recommendations, Assessment, Development, and Evaluation criteria and treatment recommendations. Insights into the deliberations of the International Liaison Committee on Resuscitation task force members are provided in Values and Preferences sections. Finally, the task force members have pri-oritised and listed the top 3 knowledge gaps for each population, intervention, comparator, and outcome question.

    The use of trimethylsilyl cyanide (TMSCN) as a reagent for the direct formation of trimethylsilyl cyanohydrin ethers 3 from ketones is reported. The advantages in using TMSCN as opposed to hydrogen cyanide are illustrated by the formation of cyanohydrin ethers of ketones that do not form stable cyanohydrins. The reduction of derivatives 3 with lithium aluminum hydride is reported to afford fi-aminomethyl alcohols 4 in good yield. The combined carbonyl derivatization-reduction sequence should afford a general synthesis of 4 useful in executing ring expansion reactions. A great deal of attention has been devoted to the conversion of ketones to p-aminomethyl alcohols 4. Interest in these derivatives has largely centered around their use in the Tiffeneau-Demjanov ring expansion of cycloalkanones.2 The major difficulty in this general homologation process has been associated with the lack of reliable routes to p-aminomethyl alcohols. The two classical methods for effecting this transformation have involved the formation and subsequent reduction of either ketone cyanohydrins3 2 or P-nitromethyl alc o h o l~.~ Both procedures have suffered from lack of generality and low overall yields for the desired transformat i~n .~ For the more widely used homologation sequence proceeding through ketone cyanohydrins, the yield of pamino alcohol 4 is directly dependent upon the stability of the cyanohydrin 2, the formation of which is highly dependent upon the steric and strain factors in the ketone.6 Recently Parham and coworkers have shown that cyanohydrin ethers can be prepared by the acid-catalyzed addition of HCN to both alkyl78 and trimethylsilyl enol ethers,7b,c and that the resultant cyanohydrin derivatives can be reduced with LiA1H4 to the desired p-amino ethers or alcohols. Although this approach results in the synthesis of derivatives of unstable cyanohydrins, the sequence requires the synthesis of the appropriate enol derivative, thus lengthening as well as restricting the homologation sequence to those systems for which enol ethers are easily prepared. In conjunction with our interests in exploring the utility of trimethylsilyl cyanide (TMSCN)g as a useful reagent in organic synthesis, we would like to report on its advantages in effecting carbonyl aminomethylation via the asilyloxy nitriles 3 (eq I). Our previous studies have shown that, in contrast to the substrate sensitivity of HCN-carbonyl addition reactions, the addition of TMSCN to both ketones and aldehydes is a general, high-yield process.8 Apparently this is a consequence of the alteration in the AH for the carbonyl addi
