  • Publication number: 20230293062
    Abstract: An aspect of an embodiment or partial embodiment of the present invention (or combinations of various embodiments in whole or in part of the present invention) comprises, but not limited thereto, a method and system (and related computer program product) for continually assessing the risk of hypoglycemia for a patient and then determining what action to take based on that risk assessment. A further embodiment results in two outputs: (1) an attenuation factor to be applied to the insulin rate command sent to the pump (either via conventional therapy or via open or closed loop control) and/or (2) a red/yellow/green light hypoglycemia alarm providing to the patient an indication of the risk of hypoglycemia. The two outputs of the CPHS can be used in combination or individually.

  • Patent number: 11759566
    Abstract: System and method to improve drug delivery to identified regions in the brain or elsewhere through direct infusion of a therapeutic agent or the like into that region. This direct infusion will allow for greater concentrations of the agent in the target region while reducing concentrations elsewhere in the body where these agents may be toxic. The system and method improves efficacy while reducing unwanted side effects. The system includes an array of multiple, independently targeted, microporous catheters for insertion into the target region and a distribution system that allows for individualized flow control to each catheter. The system may be connected to a reservoir that contains the therapeutic agent, and flow to the system is maintained through one or more pumps. This system will greatly improve on the current single catheter infusion design and shall provide therapy, delivered through multiple catheters, thus delivering the therapy evenly over a customizable volume.

  • Patent number: 11754652
    Abstract: Polarized nuclear imaging and spectroscopy systems and methods are disclosed. In some embodiments, nuclei of a radioactive substance are polarized such that the spins of the nuclei are oriented in a specific direction, to generate a polarized radioactive tracer with anisotropic gamma ray emission. The radioactive substance is selected such that the degree of anisotropy is enhanced. A tracer is introduced into a living subject for delivery to a target area of interest in the subject. The tracer is delivered such that nuclear spin relaxation of the tracer is inhibited during transport of the tracer to the target area of interest. Gamma rays from the gamma ray emission are detected, and based on the detected gamma rays and properties associated with the anisotropic gamma ray emission, imaging data and/or spectroscopic data are obtained that are associated with the tracer in the subject.

  • Patent number: 11747419
    Abstract: Systems and methods for performing ungated magnetic resonance imaging are disclosed herein. A method includes producing magnetic resonance image MRI data by scanning a target in a low magnetic field with a pulse sequence having a spiral trajectory; sampling k-space data from respective scans in the low magnetic field and receiving at least one field map data acquisition and a series of MRI data acquisitions from the respective scans; forming a field map and multiple sensitivity maps in image space from the field map data acquisition; forming target k-space data with the series of MRI data acquisitions; forming initial magnetic resonance images in the image domain by applying a Non-Uniform Fast Fourier Transform to the target k-space data; and forming reconstructed images with a low rank plus sparse (L+S) reconstruction algorithm applied to the initial magnetic resonance images.

  • Publication number: 20230241173
    Abstract: Inflammatory cell recruitment to local sites of tissue injury and/or infection is controlled by many signaling processes influencing cell-to-cell interactions between vascular endothelial cells (EC) in post-capillary venules and circulating leukocytes. Here we report that the ATP-release channel Pannexin1 (Panx1) opens downstream of EC activation by tumor necrosis factor ? (TNF?). This process involves activation of Type 1 TNF receptors, recruitment of Src Family Kinases (SFK), and SFK-dependent phosphorylation of Panx1. We report a previously unidentified role for Panx1 channels in promoting leukocyte adhesion and emigration through the venous wall during acute systemic inflammation. The present application further discloses that Panx IL2 peptide consisting of amino acid sequence KYPIVEQYLKYGRKKQRR (SEQ ID NO:3) or 10Panx1 peptide consisting of amino acid sequence WRQAAFVDSY (SEQ ID NO:8) are inhibitors of leukocyte adhesion.
