Method for binding site identification by molecular dynamics simulation (silcs: site identification by ligand competitive saturation)

The invention describes an explicit solvent all-atom molecular dynamics methodology (SILCS: Site Identification by Ligand Competitive Saturation) that uses small aliphatic and aromatic molecules plus water molecules to map the affinity pattern of a large molecule for hydrophobic groups, aromatic groups, hydrogen bond donors, and hydrogen bond acceptors. By simultaneously incorporating ligands representative of all these functionalities, the method is an in silico free energy-based competition assay that generates three-dimensional probability maps of fragment binding (FragMaps) indicating favorable fragment:large molecule interactions. The FragMaps may be used to qualitatively inform the design of small-molecule ligands or as scoring grids for high-throughput in silico docking that incorporates both an atomic-level description of solvation and the large molecule's flexibility.

Energy expenditure

Aspects relate to calculating energy expenditure values from an apparatus configured to be worn on an appendage of a user. Steps counts may be quantified, such as by detecting arm swings peaks and bounce peaks in motion data. A search range of acceleration frequencies related to an expected activity may be established. Frequencies of acceleration data within a search range may be analyzed to identify one or more peaks, such as a bounce peak and an arm swing peak. Novel systems and methods may determine whether to utilize the arm swing data, bounce data, and/or other data or portions of data to quantify steps. The number of peaks (and types of peaks) may be used to choose a step frequency and step magnitude. At least a portion of the motion data may be classified into an activity category based upon the quantification of steps.

Label-free biomolecular interaction analysis using a rapid analyte dispersion injection method
09990464 · 2018-06-05 · ·

Dispersion injection methods for determining biomolecular interaction parameters in label-free biosensing systems are provided. The methods generally relate to the use of a single analyte injection that generates a smoothly-varying concentration gradient via dispersion en route to a sensing region possessing an immobilized binding partner. The present method incorporates the use of an internal standard which provides a reference as to the dispersion conditions present which can then be used to calculate an effective diffusion coefficient for the analyte of interest based on a universal calibration function. The effective diffusion coefficient can then be incorporated into the appropriate dispersion model to provide a calibrated dispersion model. The calibrated dispersion model can then be incorporated into the desired interaction model to provide a reliable representation of the analyte concentration at the sensing region at any time during the injection. The use of the internal standard and universal calibration function permit use of a wide range of injection conditions which may not otherwise be consistent with a particular dispersion model. Thus, the present methods allow for higher flow rates and lower sample volumes thereby increasing assay speed and decreasing sample consumption.
