Abstract: A method (and system) of segmenting one or more histological structures in a tissue image represented by multi-parameter cellular and sub-cellular imaging data includes receiving coarsest level image data for the tissue image, wherein the coarsest level image data corresponds to a coarsest level of a multiscale representation of first data corresponding to the multi-parameter cellular and sub-cellular imaging data. The method further includes breaking the coarsest level image data into a plurality of non-overlapping superpixels, assigning each superpixel a probability of belonging to the one or more histological structures using a number of pre-trained machine learning algorithms to create a probability map, extracting an estimate of a boundary for the: one or more histological structures by applying a contour algorithm to the probability map, and using the estimate of the boundary to generate a refined boundary for the one or more histological structures.

Abstract: Described herein is a new antidote for the rapid elimination of carbon monoxide from hemoglobin, including brain, heart, and red cell hemoglobin. The disclosed therapy involves the use of modified human globins, particularly neuroglobins modified at residue 64 and cytoglobins modified at residue 81, which bind carbon monoxide with extremely high affinity. The monomeric mutant globins are infused into blood, where they rapidly and irreversibly sequester carbon monoxide, and thus limit toxic effects of carbon monoxide on cellular respiration and oxygen transport and utilization.

Abstract: Disclosed herein are methods of identifying biomarkers (such as genes (e.g., RNA or mRNA), proteins, and/or small molecules) that can be used to predict organ or tissue function or dysfunction. In some embodiments, the methods include ex vivo perfusion of the organ or tissue, collection of samples from the organ or tissue (for example, perfusate, fluids produced by the organ (such as bile or urine), or tissue biopsies) and measuring the level of one or more biomarkers in the sample. It is also disclosed herein that an analysis of biomarkers (such as genes (e.g., RNA or mRNA), proteins, and/or small molecules) present in a biological sample from an organ, tissue, or subject can be used to identify whether the organ, tissue, or subject is at risk for (or has) organ dysfunction or organ failure.

Abstract: Methods are disclosed for generating a target mean arterial pressure (MAP) for a patient during a surgery. In some implementations, the disclosed methods include calculating the target MAP based on the age, biological sex, emergent surgery status, and American Society of Anesthesiology (ASA) physical status (PS) class of the patient, and a predetermined intraoperative hypotension (IOH) risk benchmark. Treating the patient to maintain a MAP at or above the target MAP during the surgery reduces a risk of IOH during the surgery, a risk of administering an unnecessary therapy to avoid IOH during the surgery; and a risk of not administering a therapeutic MAP-decreasing action during the surgery. In some implementations, the method further comprises conducting the surgery on the patient and treating the patient to maintain the MAP of the patient at or above the target MAP during the surgery. Also provided are systems for implementing the disclosed methods.

Abstract: Methods and devices for determining a mass concentration of an airborne or respirable species in real time are provided. Methods can include drawing in a particulate species through an inlet and into a chamber of a resonator of a monitoring device and directing a laser beam into the chamber of the resonator and toward the particulate species such that the particulate species absorbs energy from the laser beam and transmits heat to the surrounding air within the chamber of the resonator. A power of the laser beam as it leaves the resonator and a sound pressure within the chamber of the resonator can be determined. Determining a mass concentration of the particulate species based on a ratio of the measured sound pressure and power of the laser beam, and whether the mass concentration of the particulate species exceeds a threshold concentration can be achieved.

Abstract: Disclosed cannula systems can detect the tissue type within which the cannula tip is located in real time using electrodes adjacent the cannula tip. The sensing cannula system can differentiate when the cannula tip is in adipose tissue or muscle based on electrical impedance. The system can be used in fat grafting and liposuction procedures, for example. An operator can detect if the cannula tip enters muscle by watching for an indicator light or audible alarm that is automatically activated by the device based on a change in sensed impedance. The device may also stop the flow of fat through a pump halting injection into the sub-muscular space.
