1% vs 50.9%; p = .03) without a difference in airway complications. Other patient cofactors did not have an impact on perioperative tracheotomy or airway complication rate.\n\nConclusionsElective tracheotomy may safely be avoided in a subset of patients undergoing maxillectomy with microvascular reconstruction. Elective tracheotomy Selleckchem AZD9291 should be considered in patients

“The prevalence of uric kidney stone increases regularly, due to its high correlation with obesity, HTA, metabolic syndrome, diabetes and elderly age. The surgical treatment of urolithiasis may not be always easy, and the lithotripsy has a very low efficiency. So, an appropriate medical prescription, with a good patient observance, is very effective regarding kidney stone dissolution as well as for recurrence prevention. The urinary pH is acidic, which is the main factor of lithogenesis. It must be corrected by the alkalization of the urines. The potassium citrate treatment is very efficient, and has low side effects. It must be prescribed diluted in 1.5 L of water, to be effective all over the day and to avoid gastro-intestinal disorders. (C) 2013 Elsevier Masson SAS. All rights reserved.”
“The study

of synchronization phenomena in coupled dynamical systems is an active field of research in many scientific disciplines including the neurosciences. Over the last decades, a selleck chemical Microbiology inhibitor number of time series analysis techniques have been proposed to capture both linear and nonlinear aspects of interactions. While most

of these techniques allow one to quantify the strength of interactions, developments that resulted from advances in nonlinear dynamics and in information and synchronization theory aim at assessing directed interactions. Most of these techniques, however, assume the underlying systems to be at least approximately stationary and require a large number of data points to robustly assess directed interactions. Recent extensions allow assessing directed interactions from short and transient signals and are particularly suited for the analysis of evoked and event-related activity.”
“Soils derived from serpentinite (serpentine soils) often have low macronutrient concentrations, exceedingly low Ca:Mg molar ratios and high heavy metal concentrations, typically resulting in sparse vegetative cover. This combined suite of edaphic stresses is referred to as the “serpentine syndrome.” Although several plant community-level studies have been conducted to identify the most important edaphic factor limiting plant growth on serpentine, the primary factor identified has often varied by plant community and local climate. Few studies to date have been conducted in serpentine plant communities of alpine or boreal climates.
