Transmural Ultrasound-based Visualization of Patterns of Action Potential Wave Propagation in Cardiac Tissue
The pattern of action potential propagation during various tachyarrhythmias is strongly suspected to be composed of multiple re-entrant waves, but has never been imaged in detail deep within myocardial tissue. An understanding ...
EndophilinAs regulate endosomal sorting of BDNF-TrkB to mediate survival signaling in hippocampal neurons
The sorting of activated receptors into distinct endosomal compartments is essential to activate specific signaling cascades and cellular events including growth and survival. However, the proteins involved in this sorting ...
Key Components of Different Plant Defense Pathways Are Dispensable for Powdery Mildew Resistance of the Arabidopsis mlo2 mlo6 mlo12 Triple Mutant.
Loss of function mutations of particular plant MILDEW RESISTANCE LOCUS O (MLO) genes confer durable and broad-spectrum penetration resistance against powdery mildew fungi. Here, we combined genetic, transcriptomic and ...
AncientGeek: Primary Sources Powering Historical Language Learning
(Association for the Advancement of Computing in Education (AACE), 2014)
This paper showcases development on a digital learning environment built for users interested in ancient languages. The environment adopts a two-pronged approach: first, it assesses user progress during the language learning ...
Motor modules of human locomotion: influence of EMG averaging, concatenation, and number of step cycles.
Locomotion can be investigated by factorization of electromyographic (EMG) signals, e.g., with non-negative matrix factorization (NMF). This approach is a convenient concise representation of muscle activities as distributed ...
A musculoskeletal model of human locomotion driven by a low dimensional set of impulsive excitation primitives
Human locomotion has been described as being generated by an impulsive (burst-like) excitation of groups of musculotendon units, with timing dependent on the biomechanical goal of the task. Despite this view being supported ...
Bazooka/PAR3 is dispensable for polarity in Drosophila follicular epithelial cells.
Apico-basal polarity is the defining characteristic of epithelial cells. In Drosophila, apical membrane identity is established and regulated through interactions between the highly conserved Par complex (Bazooka/Par3, ...
DNA damage-induced translocation of S100A11 into the nucleus regulates cell proliferation
Background Proteins are able to react in response to distinct stress stimuli by alteration of their subcellular distribution. The stress-responsive protein S100A11 belongs to the family of multifunctional S100 proteins ...
Synaptic scaling in combination with many generic plasticity mechanisms stabilizes circuit connectivity
Synaptic scaling is a slow process that modifies synapses, keeping the firing rate of neural circuits in specific regimes. Together with other processes, such as conventional synaptic plasticity in the form of long term ...
Spike-Triggered Covariance Analysis Reveals Phenomenological Diversity of Contrast Adaptation in the Retina.
When visual contrast changes, retinal ganglion cells adapt by adjusting their sensitivity as well as their temporal filtering characteristics. The latter has classically been described by contrast-induced gain changes that ...
