Neural Development of Deductive Reasoning

Children's understanding of linear-order (e.g., Dan is taller than Lisa, Lisa is taller than Jess) and set-inclusion (i.e., All tulips are flowers, All flowers are plants) relationships is critical for the acquisition of deductive reasoning, that is, the ability to reach logically valid conclusions from given premises. Behavioral and neuroimaging studies in adults suggest processing differences between these relations: While arguments that involve linear-orders may be preferent...

Investigation of the Safety and Efficacy of Pocket-X Gel and Pocket-X Chip

This study is a prospective randomized open-label controlled study in which the Pocket-X Gel, a periodontal in-situ gelling product, or Pocket-X Chip, a periodontal film, will be applied to periodontal pockets in one mouth segment of patients in the treatment groups following scaling and root planing, while a control group will only undergo scaling and root planing. The aim of the study is to investigate the safety and efficacy of Pocket-X Gel and Pocket-X Chip in improving the...

Injury Incidence in Professional Soccer

The winter break within the German Professional Football Leagues will be shortened as for the season 2009/2010 from 6.5 to 3.5 weeks. That might have repercussions on injury incidence in either way, positive or negative. On the one hand, recovery time during the winter will be shorter, which might lead to an increased risk of injury. On the other hand, it will allow a better spread of games in the second round, thus reducing the amount of the so-called "English weeks", which i...

Diaphragmatic Motion Using Linear Ultrasound

This study evaluates the movement of the diaphragm (which is the main muscle used for breathing). It will compare two ultrasound modalities: linear ultrasound versus curvilinear ultrasound, at measuring diaphragm motion. Our proposed measurement method with linear ultrasound is novel, and will be compared against the established method with curvilinear ultrasound. We hypothesize that our novel method will have several potential advantages, including: it may be easier to learn, ...

Voriconazole Trough Plasma Levels : Genetic Polymorphism, Efficacy, Safety in Patients With Hematologic Malignancy

Multiple factors are associated with a large variability in voriconazole exposure following standard dose administration, such as non-linear saturable pharmacokinetics, drug-drug interactions, liver disease, patient age, and genetic polymorphism of the metabolic enzymes. Voriconazole is extensively metabolized by the human hepatic enzymes, primarily mediated by CYP2C19. The polymorphisms account for a relatively large portion of inter-individual variance observed in voriconazo...
