  • Publication number: 20240074003
    Abstract: A hand warming device includes a housing, a heating control circuit received in the housing including a front housing and a back housing connected with the front housing, a heat conducting member surrounding around the housing, a heat generating member clamped between the housing and the heat conducting member, and a temperature sensor. The heat generating member horizontally wraps on a right side and/or a left side of the front and back housings; correspondingly, the heat conducting member horizontally wraps on the right side and/or the left side of the front and hack housings. After the heat conducting member is arranged on the front and back housings, the heat conducting member covers on and abuts against the heat generating member. Both the heat generating member and the heat conducting member of the present disclosure are arranged around the left and right sides of the housing to improve heating effect.

  • Publication number: 20220187321
    Abstract: Disclosed herein are methods for diagnosing a subject as having a neurological disorder, such as Alzheimer's disease, using proximity-based detection assays capable of detecting complexes containing two or more synaptic proteins, such as neuronal pentraxins, from a blood, cerebrospinal fluid, or other fluid sample of the subject. Also disclosed are methods of evaluating and monitoring subjects having or at risk of developing a neurological disorder using the aforementioned assays.

  • Patent number: 10914749
    Abstract: The present invention relates to the field of cognitive function. More specifically, the present invention provides compositions and methods useful for assessing cognitive dysfunction/function in Alzheimer's disease and other diseases of cognition. In one embodiment, the method comprises the steps of (a) reducing heterocomplexes comprising NPTX1 and NPTX2 present in a biological sample obtained from the patient into NPTX1 and NPTX2 monomers; (b) covalently modifying the thiol groups of the NPTX1 and NPTX2 monomers to prevent re-formation of NPTX1/NPTX2 heterocomplexes; (c) detecting NPTX2 in the sample; and (d) assessing cognitive function in the patient by comparing NPTX2 detected in the sample to a control.
