Abstract: Systems and methods are disclosed for quantifying blood flow using time-varying kinetic modeling of high temporal-resolution dynamic positron emission tomography (PET) data. A single tracer is introduced into the body. A first set of images is acquired, via PET, of at least a portion of the body at a plurality of predetermined time intervals. Based on the first set of images, an intensity of the tracer in the at least the portion of the body is determined as a function of time. The intensity of the tracer as a function of time is modeled using a time-varying kinetic model. Based on the model, the blood flow through the at least the portion of the body is quantified. Additional images may be acquired and used to quantify additional parameter(s), such as glucose metabolism, amyloid load, etc., with the single tracer.

Abstract: The invention provides cells that have an increased Signal Regulatory Protein Alpha (SIRP??) engagement function (SIRP? engager cells) that resist innate immunity when transplanted into a subject when compared to a parental cell having an unmodified SIRP? engagement function. The SIRP? engager cells lack an intact CD47 cytoplasmic signalling function. In some embodiments, the SIRP? engager cells are hypoimmune cells. In other embodiments, the SIRP? engager cells are differentiated somatic cells. In other embodiments, the SIRP? engager cells are hypoimmune pluripotent (HIP) cells. In further embodiments, the HIP cells are blood type O (HIPO), Rhesus factor (Rh)negative (HIP?) or both type O and Rh? (HIPO?). In other embodiments, the SIRP? engager cells have been derived or differentiated from HIP, HIP?, or HIPO? cells. In other embodiments, the SIRP? engager cells comprise an antibody Fc receptor to protect against antibody dependent cellular cytotoxicity (ADCC) or complement dependent cytotoxicity (CDC).

Abstract: A low power-consumption iontronic pressure sensor is disclosed that is based on OECT where an ionic hydrogel is used as solid gating medium for pressure sensing transistor elements formed thereon. The pressure sensor includes a substrate containing one or more pressure sensing transistor elements with each transistor element including a source electrode, a drain electrode, and a channel formed from a material comprising an electrically conducting polymer. A microstructured solid gel electrolyte having a plurality of microstructures formed thereon serves as the gating medium and is disposed atop the channel. A gate electrode is disposed on the microstructured solid gel electrolyte. The resultant iontronic pressure sensor may be operated at voltages less than 1 V, with a power-consumption between ˜101-103 ?W, while maintaining a tunable sensitivity between 1˜10 kPa?1.

Abstract: A deep learning-based digital staining method and system are disclosed that enables the creation of digitally/virtually-stained microscopic images from label or stain-free samples based on autofluorescence images acquired using a fluorescent microscope. The system and method have particular applicability for the creation of digitally/virtually-stained whole slide images (WSIs) of unlabeled/unstained tissue samples that are analyzes by a histopathologist. The methods bypass the standard histochemical staining process, saving time and cost. This method is based on deep learning, and uses, in one embodiment, a convolutional neural network trained using a generative adversarial network model to transform fluorescence images of an unlabeled sample into an image that is equivalent to the brightfield image of the chemically stained-version of the same sample.
