Предметом описываемой полезной модели является электроприбор, предназначенный для получения, хранения и точного дозирования препарата - гидроколлоидного наносеребра. Данная разработка относится к области медицинской электротехники и приборостроения и применима в областях: фармакологии, гуманной и ветеринарной медицины, зоотехники, лабораторной техники и оборудования, растениеводства, а также в сфере быта. Осуществление полезной модели достигается путем монтажа основных конструктивных элементов электролитического генератора внутри медицинского инъекционного шприца. При этом пара серебряных (999,9) электродов (1) закрепляется на поверхности поршня шприца (2) таким образом, чтобы электрическая контактная часть электрода проходила сквозь поршень и была герметично в него вмонтирована (3). При этом максимально большая часть рабочей поверхности серебряных электродов должна быть размещена внутри цилиндра шприца (7), а место электрического соединения электрода с электрическим разъемом или электрокабелем - в толще массы герметика (3) с внешней стороны поршня. Штекерный электрический разъем (4) также крепится на поверхности штока шприца (5) и служит как для подключения генератора к внешнему источнику питания и электронных блоков, так и для мануального переключения с целью изменения электрической полярности. Такой электролитический генератор способен работать с любым низковольтным источником электропитания, работающим в миллиамперном диапазоне, не зависимо от характера тока. Настоящей полезной моделью также предусмотрено создание адаптера (6), обеспечивающего подключение штекерного разъема генератора к внешним USB-источникам тока, либо электронно-измерительному оборудованию. Для производства коллоидного наносеребра внутреннюю полость шприца заполняют дистиллированной водой, затем удаляют излишний воздух и подключают генератор к соответствующему источнику электропитания.

Microencapsulated catalyst

Номер: US20120016139A1
Автор: Mohammed Nisar, Thomas Eric Oliver Screen
Принадлежит: REAXA Ltd

The present invention relates to a catalyst system. In particular the invention relates to a catalyst in the form of metal or an alloy that is encapsulated within a polymer shell or matrix. More specifically the invention is directed towards reactive catalytic metals that may be pyrophoric or otherwise reactive in air and/or susceptible to oxidation. In particular, the invention is concerned with catalysts based on nickel. Raney or sponge nickel is highly hazardous: a self-igniting solid; produces hazardous fumes when burning; causes irritation of the respiratory tract, nasal cavities; causes pulmonary fibrosis if inhaled; ingestion may lead to convulsions and intestinal disorders; causes eye and skin irritation; and chronic exposure may lead to pneumonitis and sensitization (“nickel itch”). The invention provides metal catalysts that avoid such problems and have a good shelf life and working life.

The present invention contemplates induction of immunological tolerance thereby providing permanent allogcaft acceptance. This method obviates the need for a lifelong regimen of immunosuppressive agents which can increase the risk of infection, autoimmunity, and cancer. Immunological tolerance is thought to be mediated by regulatory T lymphocytes (T reg cells) with immunosuppressive capabilities. A therapeutically relevant platform comprising artificial constructs are contemplated comprising numerous soluble and surface bound T reg cell stimulating factors that may induce tolerance following allograft transplantation. Such artificial constructs, being the size of a cell, have surface bound monoclonal antibodies specific to regulatory T-cell surface moieties and encapsulated soluble regulatory T-cell modulating factors.

An improved process for producing substantially non-polar doped or un-doped cerium oxide nanoparticle dispersions is disclosed. The cerium-containing oxide nanoparticles of an aqueous colloid are transferred to a substantially non-polar liquid comprising one or more amphiphilic materials, one or more low-polarity solvents, and one or more glycol ether promoter materials. The transfer is achieved by mixing the aqueous and substantially non-polar materials, forming an emulsion, followed by a phase separation into a remnant polar solution phase and a substantially non-polar organic colloid phase. The organic colloid phase is then collected. The promoter functions to speed the transfer of nanoparticles to the low-polarity phase. The promoter accelerates the phase separation, and also provides improved colloidal stability of the final substantially non-polar colloidal dispersion. Importantly, the glycol ether promoter reduces the temperature necessary to achieve the phase separation, while providing high extraction yield of nanoparticles into the low-polarity organic phase. 1.

A process of forming microcapsules is described. The microcapsule population is formed by providing an anionic or cationic, solid hydrophilic core material; providing an oil continuous phase, the oil continuous phase comprising one or more esters with chain length up to about 18 carbons. Emulsification is achieved by subjecting the mixture to high shear agitation and heating the mixture for a time sufficient to enable acid or amine acrylate or methacrylate and multifunctional acrylate or methacrylate to form a prepolymer which migrates to the anionic or cationic solid hydrophilic material, thereby forming prepolymers adhered to the hydrophilic core materials. Temperature is held or heating continued for a time sufficient to enable the prepolymer to flow onto and coalesce into a continuous film surface coating on the hydrophilic core material. Heating is carried out or light exposure or both for a time and temperature sufficient to cross link the prepolymers. 1.

The present invention generally relates to droplets and/or emulsions, such as multiple emulsions. In some cases, the droplets and/or emulsions may be used in assays, and in certain embodiments, the droplet or emulsion may be hardened to form a gel. In some aspects, a heterogeneous assay can be performed using a gel. For example, a droplet may be hardened to form a gel, where the droplet contains a cell, DNA, or other suitable species. The gel may be exposed to a reactant, and the reactant may interact with the gel and/or with the cell, DNA, etc., in some fashion. For example, the reactant may diffuse through the gel, or the hardened particle may liquefy to form a liquid state, allowing the reactant to interact with the cell. As a specific example, DNA contained within a gel particle may be subjected to PCR (polymerase chain reaction) amplification, e.g., by using PCR primers able to bind to the gel as it forms. As the DNA is amplified using PCR, some of the DNA will be bound to the gel via the PCR primer. After the PCR reaction, unbound DNA may be removed from the gel, e.g., via diffusion or washing. Thus, a gel particle having bound DNA may be formed in one embodiment of the invention. 120-. (canceled)21.
