Dynamic and flexible H3K9me3 bridging via HP1β dimerization establishes a plastic state of condensed chromatin.
Histone H3 trimethylation of lysine 9 (H3K9me3) and proteins of the heterochromatin protein 1 (HP1) family are hallmarks of heterochromatin, a state of compacted DNA essential for genome stability and long-term transcriptional ...
Motion processing with wide-field neurons in the retino-tecto-rotundal pathway
The retino-tecto-rotundal pathway is the main visual pathway in non-mammalian vertebrates and has been found to be highly involved in visual processing. Despite the extensive receptive fields of tectal and rotundal wide-field ...
Neuromuscular adjustments that constrain submaximal EMG amplitude at task failure of sustained isometric contractions.
The amplitude of the surface EMG does not reach the level achieved during a maximal voluntary contraction force at the end of a sustained, submaximal contraction, despite near-maximal levels of voluntary effort. The ...
Sympathetic activation by the cold pressor test does not increase the muscle force generation capacity.
A positive inotropic action by the sympathetic nervous system on skeletal muscles has been observed and investigated in animal and in vitro studies. This action provided a theoretical basis for the putative ergogenic action ...
Segment Tracking via a Spatiotemporal Linking Process including Feedback Stabilization in an n-D Lattice Model
Model-free tracking is important for solving tasks such as moving-object tracking and action recognition in cases where no prior object knowledge is available. For this purpose, we extend the concept of spatially synchronous ...
FTIR-ATR-based prediction and modelling of lignin and energy contents reveals independent intra-specific variation of these traits in bioenergy poplars
Background There is an increasing demand for renewable resources to replace fossil fuels. However, different applications such as the production of secondary biofuels or combustion for energy production require different ...
Identification of markers associated with bacterial blight resistance loci in cowpea [Vigna unguiculata (L.) Walp.]
Cowpea bacterial blight (CoBB), caused by Xanthomonas axonopodis pv. vignicola (Xav), is a worldwide major disease of cowpea [Vigna unguiculata (L.) Walp.]. Among different strategies to control the disease including ...
Amino Acid- vs. Peptide-Odorants: Responses of Individual Olfactory Receptor Neurons in an Aquatic Species
Amino acids are widely used waterborne olfactory stimuli proposed to serve as cues in the search for food. In natural waters the main source of amino acids is the decomposition of proteins. But this process also produces ...
A Small Fraction of Strongly Cooperative Sodium Channels Boosts Neuronal Encoding of High Frequencies
Generation of action potentials (APs) is a crucial step in neuronal information processing. Existing biophysical models for AP generation almost universally assume that individual voltage-gated sodium channels operate ...
Cross-Modal Distortion of Time Perception: Demerging the Effects of Observed and Performed Motion
Temporal information is often contained in multi-sensory stimuli, but it is currently unknown how the brain combines e.g. visual and auditory cues into a coherent percept of time. The existing studies of cross-modal time ...
