  • Publication number: 20210169409
    Abstract: A flexible system capable of utilizing data from different monitoring techniques and capable of providing assistance to patients with diabetes at several scalable levels, ranging from advice about long-term trends and prognosis to real-time automated closed-loop control (artificial pancreas). These scalable monitoring and treatment strategies are delivered by a unified system called the Diabetes Assistant (DiAs) platform. The system provides a foundation for implementation of various monitoring, advisory, and automated diabetes treatment algorithms or methods. The DiAs recommendations are tailored to the specifics of an individual patient, and to the patient risk assessment at any given moment. A central data exchange node or server collects patient data from individual DiAs devices and provides safety assurance, monitoring, telemedicine and database building for the DiAs system.

  • Patent number: 11020457
    Abstract: The effects of hepcidin treatment on mitigating ischemia reperfusion injury (IRI) and acute kidney injury (AKI) by decreasing iron availability and ROS-mediated cell death were tested. Wild type (WT) C57Bl/6 and hepcidin knock out (Hamp?/?) mice were treated with saline or 50 ?g of hepcidin i.p. prior to bilateral renal IRI. Renal function, injury markers, histopathology, and inflammation were examined after 24 hours of reperfusion. In WT mice, IRI induced increases in serum and kidney non-theme iron levels, but hepcidin treatment induced sequestration of iron in the spleen and liver and prevented IRI-associated increases in serum and kidney non-heme iron. Kidney function was significantly better in hepcidin-treated mice, accompanied by less acute tubular necrosis and reduced infiltration of immune cells. Hepcidin treatment decreased kidney ferroportin expression and induced the expression of cytoprotectant, H-Ferritin, and was associated with less ROS and tubular epithelial apoptosis.

  • Patent number: 11013406
    Abstract: System and Method pertaining to the modification and integration of an existing consumer digital camera, for example, with an optical imaging module to enable point and shoot fundus photography of the eye. The auto-focus macro capability of existing consumer cameras is adapted to photograph the retina over an extended diopter range, eliminating the need for manual diopter focus adjustment. The thru-the-lens (TTL) auto-exposure flash capability of existing consumer cameras is adapted to photograph the retina with automatic flash exposure eliminating the need for manual flash adjustment. The consumer camera imaging sensor and flash are modified to allow the camera sensor to perform both non-mydriatic focusing of the retina using infrared illumination and standard color flash photography of the retina without the need for additional imaging sensors or mechanical filters.

  • Publication number: 20210140883
    Abstract: An apparatus related method for measuring a property of a target material. The system may include a pump device that generates a pump beam. A modulation device may receive the pump beam and generate a modulated pump beam by modulating an intensity amplitude of the pump beam, which may be directed to the target material. A probe device may generate a probe beam, which is directed to the target material. A part of the probe beam may be reflected off of the target material, and has similar frequency characteristic as the modulated pump beam. A detection device may detect the reflected probe beam and produce a signal. An analyzing device may receive the signal and calculate the target material property by comparing the modulated frequency characteristics of the signal to those of the pump beam. At least one of the pump and the probe beams may be infrared light.

  • Patent number: 10995374
    Abstract: The gene responsible for encoding SERT has a functional polymorphism at the 5?-regulatory promoter region, which results in two forms, long (L) and short (S). The LL-genotype is hypothesized to play a key role in the early onset of alcohol use. The present invention discloses the differences in treatment and diagnosis based on the L or short genotypes as well as on a single nucleotide polymorphism of the SERT gene, the 3? UTR SNP rs1042173. The present invention demonstrates the efficacy of using the drug ondansetron and similar drugs for treatment based on variations in the polymorphisms of the SERT gene as well as methods for diagnosing susceptibility to abuse of alcohol and other addiction-related diseases and disorders.
