Abstract: The present disclosure provides methods for bulk droplet vitrification of cells, compositions including the vitrified droplets, and systems for performing the methods for bulk droplet vitrification cells.

Abstract: An adjustable height desk is disclosed herein that is configured for easy assembly and disassembly. The desk includes panels joined to form a support core for supporting a working surface. The desk also includes a planar base that is easily attached to and removed from the support core by way of protrusions on panels of the support core. The protrusions have locking holes formed therein. Through holes in the base receive the protrusions. Locking pins are inserted through the locking holes to form a compression fit. The locking pins can be sized for movement through a locking hole and for creating a compression fit when inserted into a locking hole. One end of the locking pins can be configured with a hook portion for mating with a locking pin insertion/removal tool. The tool can be utilized to insert and remove the locking pins.

Abstract: This disclosure relates to subnormothermic machine perfusion formulations for ex vivo preservation of allografts, and methods of use thereof.

Abstract: This disclosure is related to methods of preserving biological samples such as organs, and tissue. The present disclosure relates to methods of subzero preservation of biological tissue samples, such as entire organs from mammals, e.g., humans. The present disclosure is based, at least in part, on the discovery that biological tissue samples can be supercooled while minimizing formation of ice crystals by reducing liquid-air interfaces and lowering the melting point of the tissue samples, e.g., organs, or liquid in the tissue samples by use of cryoprotective agents while ensuring uniform distribution of cryoprotective agents throughout the biological sample by using improved perfusion techniques.

Abstract: This disclosure is related to methods of preserving biological samples, organs, and organisms. This disclosure is based, at least in part, on the discovery that in the presence of heterogenous extracellular ice, endothelial cells have improved attachment and viability after preservation, and particularly by uniformly nucleating ice across the microvasculature using ice nucleating agents, the chance of intracelluar ice formation can be significantly reduced.

Abstract: A pattern recognition system to qualify valid triggering for digital storage oscilloscopes. Valid trigger qualification may be established from recognition of triggering level and interval time information, as well as other pattern-related information, to start or stop waveform acquisition. Trigger qualification may be established from either a pattern match or a mismatch. The trigger recognition system may be further extended to the occurrence of complex signals, such as those associated with television, rotating machinery, or other phenomena occuring in predetermined or known patterns.

Abstract: A method of signal analysis for establishing display scaling and stable triggering for digital oscilloscopes employs amplitude and time histograms to analyze an input signal and establish the required conditions. An amplitude histogram analysis method is first used to determine the minimum and maximum amplitude levels of the signal, and then a time histogram analysis method is used to determine the predominant time intervals occurring in the input signal. From these two analyses, vertical gain adjustments and time base settings adjustments may be made either manually or automatically, and triggering levels established to provide a stable, usable display.
