  • Patent number: 10973765
    Abstract: Disclosed are cell membrane-derived nanovesicles, a method of preparing the nanovesicles, and a pharmaceutical composition and a diagnostic kit using the nanovesicles. The cell membrane-derived nanovesicles may prevent potential adverse effects because intracellular materials (e.g., genetic materials and cytosolic proteins) unnecessary for delivering therapeutic or diagnostic substances are removed from the nanovesicles. In addition, as the nanovesicles may be targeted to specific cells or tissues, therapeutic or diagnostic substances may be predominantly delivered to the targeted cells or tissues, while delivery of the substances may be inhibited. Therefore, the nanovesicles may alleviate suffering and inconvenience of patients by reducing adverse effects of therapeutic substances and by improving efficacy of the substances.

  • Patent number: 10765755
    Abstract: A delivery system of coated and uncoated nanoparticles (NP) for delivery of methylene blue (MB). The delivery system was developed using PLGA-based polymer that was repeatedly shown to be biocompatible and biodegradable. The parameters of synthesized NPs were within the suitable range for BBB permeation—specifically, the NPs were monodispersed, with slight negative charge, and with the size within 100-150 nm range suitable for intravenous delivery and delivery to the brain. The coating on the nanoparticle did not have a significant impact on the nanoparticle size and zeta potential. Based on the immunoblotting experiments using AD cellular model, the GSH coated NPs were better in reducing tau levels compared to MB solution. In vitro BBB Transwell permeation study showed eight fold higher MB-NP permeation compared to the MB solution over 24 hours.

  • Patent number: 10342747
    Abstract: The skin serves as a barrier that protects the body from the external environment and prevents water loss. This barrier function also prevents most hydrophilic or hydrophobic and large molecular weight ingredients (>500 kDa) from penetrating intact skin. Until recently, methods to increase stratum corneum permeability were generally not effective enough to make the stratum corneum so permeable that the barrier posed by the viable epidermis mattered. However, that has now changed with the development of the present embodiment's physical methods and highly optimized chemical formulations, such that we revisited the permeability of the full epidermis with the example embodiment's constructs and not focus only on the stratum corneum. This example embodiment therefore tests the hypothesis that the viable epidermis offers a significant permeability barrier to both small molecules and macromolecules that becomes the rate limiting step.

  • Patent number: 9506103
    Abstract: The invention relates to a procedure for biphasic preparation of liposomes, in the course of which technically simple and cheap mechanical mixing methods are used to commingle non-polar organic phase containing an individual mixture of natural and synthetic phospholipids and polar aqueous (buffer) phase not miscible with it, resulting in a liposome emulsion of a unique structure. Furthermore, the invention comprises embodiments of the procedure related to the in vitro diagnostic use of liposomes prepared in this way, when protein type active components are anchored to the surface of liposome membranes without application of any detergents and non-protein type active components are simply mixed with the liposome emulsion of a unique structure. In one of the possible embodiments of the procedure a Prothrombin Time (PT) reagent is prepared. Another possible embodiment of the procedure is the preparation of an activated partial thromboplastin time (APTT) reagent.

  • Patent number: 9433690
    Abstract: Methods and solutions are describes whereby radiopharmaceutical radium-224 solutions are added complex for scavenging daughter nuclide, which may enhance the overall targeting and reduces uptake of daughter nuclide in normal tissues and cells. This is accomplished without reducing the bone targeting ability of radium. The methods and solutions are convenient to use since the complexation of daughter nuclide can be done in situ in a ready to use radiopharmaceutical solution or, depending on the activity concentration, in a simple kit format by mixing two solutions and store the mixture for typically 1 minute to a few hours before administration to a patient. The use of targeted chelate scavengers for 224Ra daughter nuclide opens up the possibility for using 224Ra based solutions for medical treatments.
