Feedback has been considered a fundamental component of the motor learning process (MAGILL, 2007; SCHMIDT & LEE, 2011; SCHMIDT & WRISBERG, 2008). During and after the execution of a movement, the learner normally receives two types of feedback about the performance, intrinsic and augmented. Intrinsic feedback is information that comes from the sensory system and augmented feedback comes from an...

BACKGROUND Alcohol is traditionally known to have a relaxing effect. However, persons who consume alcohol in excessive amounts suffer from poor sleep quality and patients with alcohol use disorders commonly report insomnia. In this study, we aimed to evaluate the effects of alcohol use on sleep quality. METHODS A questionnaire-based cross-sectional survey was conducted with 234 men and 159 wo...

It has been shown by using the quail/chick chimera system that Hox gene expression in the hindbrain is influenced by positional signals arising from the environment. In order to decipher the pathway that leads to Hox gene induction, we have investigated whether a Hox gene regulator, the leucine zipper transcription factor MafB/Kr, is itself transcriptionally regulated by the environmental signa...

We previously demonstrated that jarastatin (JT), a new disintegrin from Bothrops jararaca venom, altered actin dynamics in human polymorphonuclear neutrophils (PMNs) and inhibited cell migration in vivo and in vitro (14). In this study, we evaluated the effects of JT and two other monomeric disintegrins, kistrin (KR) and flavoridin (FL), on PMN chemotaxis and chemokinesis in vitro and on the ac...

Clusters of krypton are generated in a supersonic expansion and size selected by deflection from a helium target beam. By measuring angular distributions for different fragment masses and time-of-flight distributions for fixed deflection angles and fragment masses, the complete fragmentation patterns for electron impact ionization at 70 eV are obtained from the dimer to the heptamer. For each o...

Rapidly activating K(+) current (I(Kr)) blockers prolong action potential (AP) duration (APD) in a reverse-frequency-dependent manner and may induce arrhythmias, including torsade de pointes in the ventricle. The I(Kr) blocker dofetilide has been approved for treatment of atrial arrhythmias, including fibrillation. There are, however, a limited number of studies on the action of I(Kr) blockers ...

Abstract In this paper, we have studied the particle dynamics, gravitational lensing and energy processes around black hole (BH) in Kalb–Ramond (KR) gravity. The motion of particles is considered with parameters KR BH investigated for massive massless particles. From work, got horizon structure, photon orbit ISCO (inner stable circular orbit) a mass effective potential also Additionally, tested...

How different this seems from the desolate and malaria-ridden country widely portrayed by nineteenthand early twentieth-century visitors in the region, before the modern agricultural revolution changed the face of the landscape. At another time I hope to deal at length with the matter of cultivation in the Emathian plain in antiquity. At present, however, it may be useful to attempt to understa...
