  • Publication number: 20210100915
    Abstract: The present invention relates to an antibody carrier based on a gold nanoparticle (AuNP)-aptamer conjugate and a method of preparing the same. The antibody carrier according to the present invention is prepared by binding of an immunoglobulin G (IgG) Fc domain-specific aptamer or a fluorescein isothiocyanate (FITC)-specific aptamer to AuNP, and may effectively deliver an antibody into the cell nucleus, the cytoplasm and mitochondria by specific binding of the antibody to be delivered to the aptamer. In addition, since the AuNP having very low cytotoxicity is used, the antibody carrier is not only harmless to the human body, but may also detect a location in cells easily by reflecting light at various wavelengths, and therefore, it is expected to be effectively used in diagnosis or treatment of a disease.

  • Publication number: 20210100924
    Abstract: A portable or handhold air purification system, whose air flow pipeline made of highly reflective and low absorptive material for UVC or UVB light acts also as a UV light waveguide, is invented. The system is based on the design concept of maximizing UV light exposure dosage to deactivate all the pollutants in the air flow going through to allow the system to use UVC and/or UVB LED. The system also has some features around the middle point of the air flow path to either further increase light exposure, or clean the air flow through the interaction between the specially designed nano particles and incoming UV light. Moreover, an ozone filter and an air heating devices, with energy either from the heat sink of LED's TEC or a device based on plasmonic resonance induced photothermal effects, are placed near the air outlet of the system for further enhancement. The system is very useful for travelers in the closed environment such as in a airplane, or on a train.

    Abstract: The present invention provides an improved tissue adhesive to repair defects in soft tissue. Following ASTM standard tests, crosslinked methacryloyl-substituted gelatin hydrogels of the present invention (GelSEAL) were shown to exhibit adhesive properties, i.e. wound closure strength, shear resistance and burst pressure, that were superior to clinically used fibrin- and poly(ethylene glycol)-based glues. Chronic in vivo experiments in rats proved GelSEAL to effectively seal large lung leakages without additional sutures or staples, presenting improved performance as compared to fibrin and poly(ethylene glycol) glues. Furthermore, subcutaneous implantation in rats revealed high biocompatibility of GelSEAL as evidenced by low inflammatory host response.

    Abstract: Methods and systems for the automated collection of plasma from a donor are disclosed. The methods and systems deliver anticoagulant to whole blood and/or to selected and separated components at selected times to provide a sufficient amount of anticoagulant to the selected components to prevent coagulation and/or flocculation. The methods and systems limit the amount of anticoagulant returned to the donor and maximize the amount of collected plasma. Methods and systems for maximize the collection of IgG based on a measured level of total plasma protein are also disclosed.

  • Publication number: 20210100945
    Abstract: Techniques and apparatus for de-priming processes are described. For example, in one embodiment, an apparatus may include at least one processor and a memory coupled to the at least one processor, the memory may include instructions that, when executed by the processor, may cause the at least one processor to determine a priming volume of a primer fluid infused into a priming system associated with the patient during a priming phase of the dialysis treatment, cause an ultrafiltration rate of an ultrafiltration pump of the dialysis machine in fluid communication with the patient to be changed from a treatment ultrafiltration rate to a de-priming ultrafiltration rate to remove the priming volume over a de-priming time period, and cause, after the de-priming time period, the ultrafiltration rate of the ultrafiltration pump to be changed back the treatment ultrafiltration rate. Other embodiments are described.

  • Publication number: 20210100949
    Abstract: An infusion pump includes a core member and a bladder member which are substantially spheroidal at one end and cylindrical at the other end. The core member is inserted inside the bladder member and a ring member engages the cylindrical ends of the core and bladder member to sealingly secure the bladder to the core. A tubular hose is included and is coupled with an infusion port of the core member. When fluid is injected into the pump, it causes the bladder member to inflate substantially symmetrically and spherically around an axial axis of the core member. Upon deflating the bladder member, the fluid is ejected out of the pump at a constant flow rate.

    Abstract: A controller and associated sensor system for augmenting the automatic delivery of drugs is provided. The controller and associated sensor system is based on the detection and determination of particular physical lifestyle events. As a specific example, a pump augmentation system includes a six-axis accelerometer sensor, a gyroscopic pitch sensor and a controller. The controller is configured to receive motion data from the six-axis accelerometer sensor and orientation data from the gyroscopic pitch sensor. The controller provides a pump instruction signal for changing a delivery rate of a drug to a user based on the motion data and the orientation data. When the pump is an insulin pump, the pump augmentation system is an insulin pump augmentation system and provides accurate insulin control for controlling blood glucose levels of a user.
