  • Patent number: 11630061
    Abstract: Provided herein are devices, systems, and methods for characterizing a biological sample in vivo or ex vivo in real-time using time-resolved spectroscopy. A light source generates a light pulse or continuous light wave and excites the biological sample, inducing a responsive fluorescent signal. A demultiplexer splits the signal into spectral bands and a time delay is applied to the spectral bands so as to capture data with a detector from multiple spectral bands from a single excitation pulse. The biological sample is characterized by analyzing the fluorescence intensity magnitude and/or decay of the spectral bands. The sample may comprise one or more exogenous or endogenous fluorophore. The device may be a two-piece probe with a detachable, disposable distal end. The systems may combine fluorescence spectroscopy with other optical spectroscopy or imaging modalities. The light pulse may be focused at a single focal point or scanned or patterned across an area.

  • Publication number: 20200330592
    Abstract: The present disclosure relates to methods of treating, delaying the onset, alleviating a symptom, and/or deterring the progression of a disease related to beta amyloid deposits, neurological damage, tauopathy, and/or neurodegeneration by administering a myelin sheath protein and an antibody, such as an anti-tau antibody and/or an antibody that binds amyloid beta. The present disclosure relates to methods of using a myelin sheath protein and/or an antibody, such as an anti-tau antibody and/or an antibody that binds amyloid beta, to treat or to slow the progression of a disease characterized in part by beta amyloid (A) expression or activity, or by aberrant deposition of beta amyloid in a subject, such as in Alzheimers disease, and the pathologies associated with such a disease, including for example, behavioral changes or cognitive dysfunction associated with Alzheimers disease.

  • Patent number: 10512699
    Abstract: The present subject matter relates to a non-invasive optical imaging method for monitoring early pathological events specific to Alzheimer's disease (AD), such as the development, amount and location of amyloid plaques. The ability to monitor such events provides a basis for, among other things, AD diagnosis, prognosis and assessment of potential therapies. In addition, the present subject matter introduces novel methods for treating AD and retinal ailments associated with AD. A?-plaque detection in living brains is extremely limited, especially at high resolution; therefore the present invention is based on studies focusing on the eyes as an alternative to brain-derived tissue that can be imaged directly, repetitively and non-invasively.

  • Patent number: 8562964
    Abstract: A structured drug system that is useful for delivering a drug payload to a specific tissue or cell type is disclosed. The system is based on purified polymalic acid. This polymer isolated from natural sources is biocompatible, biodegradable and of very low toxicity. The polymer is extremely water soluble and contains a large number of free carboxyl groups which can used to attach a number of different active molecules. In the examples disclosed N-hydroxysuccinimide esters of the carboxyl groups are used to attach such molecules. The active molecules include monoclonal antibodies to promote specific cellular uptake and specific pro-drugs such as antisense nucleic acids designed to modify the cellular metabolism of a target cell. The pro-drugs are advantageously linked by a somewhat labile bond so that they will be released under specific conditions. In addition, the system contains amide-linked valine to encourage membrane disruption under lysosomal conditions.

  • Patent number: 7838449
    Abstract: A dryer sheet substrate is provided having improved loft and reduced fuzz wherein the substrate comprises relatively low denier bicomponent fibers. The bicomponent fibers may comprise two or more polymers having different melting temperatures, with the relatively lower melting temperature polymer making up at least a portion of the outer surface of the fiber. Upon heating to a sufficient temperature, the lower melting temperature fibers may soften and melt, providing bonding at crossover points of the fibers in the laid web. The web indicates advantageous characteristics with respect to thickness (loft), fuzz factor and ability to absorb a fabric treating composition.

  • Publication number: 20080050337
    Abstract: Disclosed are methods of selectively delivering a medicant to an abnormal brain region and/or to a malignant tumor in a mammalian subject, including a human. A medicant is administered simultaneously or substantially simultaneously with a potassium channel activator (other than bradykinin or a bradykinin analog), such as NS-1619, EBIO, a guanylyl cyclase activating protein, an activator of soluble guanylyl cyclase (e.g., nitric oxide or a nitric oxide donor) or an activator of cyclic GMP-dependent protein kinase, whereby the medicant is delivered selectively to the cells of the abnormal brain region and/or to the tumor, compared to normal tissues. Thus, among the disclosures is a method of treating a malignant tumor in a human subject.
