  • Patent number: 11649424
    Abstract: The present disclosure relates to a pneumatic microfluidic platform for high-throughput studies of cardiac hypertrophy that enables repetitive (hundreds of thousands of times) and robust (over several weeks) manipulation of cardiac ?tissues. The platform is reusable for stable and reproducible mechanical stimulation of cardiac ?tissues (each containing only 500 cells). Heterotypic and homotypic ?tissues produced in the device were pneumatically loaded in a range of regimes, with real-time on-chip analysis of tissue phenotypes. Concentrated loading of the three-dimensional cardiac tissue faithfully recapitulated the pathology of volume overload seen in native heart tissue. Sustained volume overload of ?tissues was sufficient to induce pathological cardiac remodeling associated with upregulation of the fetal gene program, in a dose-dependent manner.

    Abstract: A fluid supply interface includes at least one supply coupling configuration, at least one discharge coupling configuration, at least one user coupling configuration, and a fluid conduit that connects the supply, discharge, and user coupling configurations to one another. A supply valve is capable of having fluid flow through it or is blocked for flow through it. A discharge valve is capable of having fluid flow through it or is blocked for flow through it. The supply valve is preloaded into a blocking position that prevents flow, and opens by means of a sufficiently large pressure difference between the two sides of the supply valve, against the preload force, for flow through in a direction from the supply coupling configuration toward the fluid conduit. The discharge valve likewise being preloaded into a closed position that prevents flow through it.

  • Patent number: 11465150
    Abstract: A reaction processor is provided with a reaction processing vessel having a channel, a liquid feeding system, a temperature control system, and a fluorescence detector, and a CPU for controlling the liquid feeding system. When a sample moves from a low temperature region to a high temperature region, the CPU instructs the liquid feeding system to stop the sample when a predetermined first waiting time has passed from the time when the passage of the sample through a fluorescence detection region is detected by the fluorescence detector. When the sample moves from the high temperature region to the low temperature region, the CPU instructs the liquid feeding system to stop the sample when a predetermined second waiting time, which is set independently of the first waiting time, has passed from the time when the passage of the sample through the fluorescence detection region is detected by the fluorescence detector.
