    摘要: The subject disclosure presents systems and computer-implemented methods for determining an acoustic time-of-flight (TOF) of sound waves through a sample material with greater accuracy and in a more repeatable fashion, by invoking one or more of an envelope generation for an error function, fitting a non-linear curve to an ultrasound frequency sweep, or performing a clustered piece-wise linear regression on individual linear parts of the ultrasonic frequency sweep. The systems and methods are useful for, among other things, monitoring diffusion of fluids through porous materials, such as tissue samples.

    摘要: An aldehyde fixative solution at a first temperature is caused to contact a tissue sample for a first time period, additionally an aldehyde fixative solution is caused to contact the tissue sample at a second temperature higher than the first temperature for a second time period. The first time period typically ranges from about 15 minutes up to about 4 hours, and the first temperature typically is from greater than 0° C. to at least 15° C. The second temperature typically is from greater than about 22° C. to about 55° C., and the second time period ranges from about 1 hour to about 4 hours. Using this process, improved tissue morphology and IHC staining as well as superior preservation of post-translation modification signals have been accomplished in approximately 4 hours compared to 24 hours for room temperature protocols, and more even morphology and antigen preservation are observed.

    摘要: The subject disclosure presents systems and computer-implemented methods for evaluating a tissue sample that has been removed from a subject. A change in speed of the energy traveling through the sample is evaluated to monitor changes in the biological sample during processing. The rate of change in the speed of the energy is correlated with the extent of diffusion. A system for performing the method can include a transmitter that outputs the energy and a receiver configured to detect the transmitted energy. A time-of-flight of acoustic waves and rate of change thereof is monitored to determine an optimal time for soaking the tissue sample in a fixative.

    摘要: The present disclosure relates to use of high-concentration aldehyde-based fixatives to fix tissue samples. Aldehyde concentrations are selected that significantly increase rate of diffusion of the fixative solution into the tissue. When combined in the cold-temperature step of a two-temperature fixation, a substantial improvement in the preservation of post-translationally modified proteins is achieved.
