  • Patent number: 7964359
    Abstract: The present invention relates to methods for enhancing the cellular uptake and clearance of soluble oligomeric A? peptide assemblies from the environment surrounding both neuronal and non-neuronal cells. Oligomeric A? peptide assembly uptake and clearance is achieved via an agent that enhances insulin receptor signaling. Such ADDL uptake enhancers represent effective anti-ADDL therapeutics for use in the therapeutic treatment and/or prophylactic treatment of diseases including Alzheimer's disease, Down's syndrome, and the like, in which compromised nerve cell function is linked to the formation and/or the activity of soluble oligomeric A? peptide assemblies, also known as ADDLs, and ADDL-related assemblies.

  • Publication number: 20080306074
    Abstract: Disclosed and claimed herein are compositions comprising ADDL receptors, related compositions, and related methods. ADDL receptors are typically, but perhaps not exclusively, localized at the post-synaptic density (PSD) of neuronal cells. Related compositions include, but are not limited to, compounds that affect, positively or negatively, ADDL binding to neuronal cells, either via one or more receptors localized at the post-synaptic density (PSD) or otherwise. Related methods include, but are not limited to, procedures to screen for compounds that affect, either positively or negatively, ADDL binding to neuronal cells, either via one or more receptors localized at the post-synaptic density (PSD) or otherwise.

  • Patent number: 7461640
    Abstract: A cooling system comprises a cooler with a hot-side passage extending between hot-side inlet and outlets. The cooler further includes a cooling passage extending between cold-side inlet and outlets. A cooling medium is disposed within the cooling passage, and is in contact with the hot-side passage to reduce the temperature of the gas or liquid passing through the hot-side passage. The cooling system is configured to regulate the condition of the cooling medium within the cooler to reduce/eliminate unwanted boiling of the cooling medium being within the cooler. The cooling system can include controller that provides an output signal in response to a detected condition of the cooling medium, and a device that receives the output signal and changes the operation of the cooling system and/or operation of an internal combustion engine to reduce the occurrence of unwanted cooling medium boiling within the cooler.
