    摘要: The systems and methods can accurately and efficiently determine a myocardial risk from a lesion disposed along a coronary segment using hemodynamic characteristic(s) associated with one or more sections of the corresponding lesion site. The method may include segmenting one or more lesion sites disposed along at least one arterial segment of the one or more arterial segments of the coronary model into one or more sections. Each lesion site includes a lesion. The method may include determining one or more characteristics for at least one section using at least the one or more characteristics associated with the at least one arterial segment. The one or more characteristics for the at least one section including hemodynamic force characteristic(s) (e.g., wall shear stress (WSS)). The method may include determining one or more risk indices for each lesion site using at least the hemodynamic force characteristic(s) for the at least one section.

    摘要: This disclosure related to methods of detecting mechanical forces required to separate ligand and receptor interactions. In certain embodiments, this disclosure relates to methods of detecting mechanical forces between a ligand and receptor, where the ligand is immobilized on a surface using weaker forces. Ligand-receptor forces lead to dissociation of the ligand that can be detected and amplified. In certain embodiments, the disclosure relates to methods of detecting ligand and receptor interactions comprising linking a ligand to one of two binding partners, wherein the binding partners have attracting forces that are less than the forces between the ligand and a receptor of the ligand such that when the ligand binds the receptor, the binding partners will separate. Separation of the binding partners can be detected.

    摘要: Mesofluidic devices for culturing cell aggregates and methods of using the same are disclosed. An exemplary mesofluidic device comprises at least one fluid inlet, at least one fluid outlet, a plurality of fluid channels, and a plurality of culture chambers. Each culture chamber can comprise at least one chamber inlet and at least one chamber outlet. The at least one chamber inlet can be in fluid communication with the at least one fluid inlet via at least one of the plurality of fluid channels. The at least one chamber outlet can be in fluid communication with the at least one fluid outlet via at least one of the plurality of fluid channels The mesofluidic device can be configured to contain a cell aggregate in each of the plurality of culture chambers.
