摘要:
The present disclosure provides recombinant bacterial cells that have been engineered with genetic circuitry which allow the recombinant bacterial cells to sense a patient's internal environment and respond by turning an engineered metabolic pathway on or off. When turned on, the recombinant bacterial cells complete all of the steps in a metabolic pathway to achieve a therapeutic effect in a host subject. These recombinant bacterial cells are designed to drive therapeutic effects throughout the body of a host from a point of origin of the microbiome. Specifically, the present disclosure provides recombinant bacterial cells comprising a heterologous gene encoding a branched chain amino acid catabolism enzyme. The disclosure further provides pharmaceutical compositions comprising the recombinant bacteria, and methods for treating disorders involving the catabolism of branched chain amino acids using the pharmaceutical compositions disclosed herein.
摘要:
The present invention relates to methods and compositions for reducing the risk and severity of C. difficile infection. It is based, at least in part, on the discovery that a restricted fraction of the gut microbiota, including the bacterium Clostridium scindens , contributes substantially to resistance against C. difficile infection. Without being bound by any particular theory, it is believed that this is achieved through the biosynthesis of secondary bile acids.
摘要:
The present invention relates to Enzyme Replacement Therapy (ERT) based on phenylalanine hydroxylase (PAH) and compositions intended for this use. It concerns an erythrocyte encapsulating PAH, especially in suspension in a pharmaceutically acceptable carrier or vehicle, a pharmaceutical composition comprising erythrocytes encapsulating PAH in a pharmaceutically acceptable carrier or vehicle, and such a pharmaceutical composition for use in the treatment or prevention of phenylketonuria (PKU) and/or other diseases involving a too high level of phenylalanine; the treatment or prevention may be in combination with a Phe-restricted diet. The invention particularly relates to classic PKU, variant PKU and non-PKU hyperphenylalaninemia.
摘要:
The present disclosure generally relates to the field of tissue engineering. The collagenous tissue produced using methods of the present disclosure is extensively cross- linked and has high mechanical properties. Specifically, the present disclosure involves an enzyme-mediated collagen-crosslinking process to produce tissue such as cartilage, and to enhance its maturation and integration.
摘要:
A smart antimicrobial material and dressing to inhibit microbial growth is provided. Endogenous chemicals, such as metabolites produced from bacteria are utilized as chemical substrates and converted by enzymes to produce a disinfecting compound that will in turn inhibit the targeted microorganism. The material shall remain passive until such time as it encounters a microbe which expresses and/or secretes specific metabolites or markers. The enzyme or enzymes embedded in the smart material converts the metabolite into a disinfecting compound, which in turn either kills the microorganism or prevents it from multiplying on the surface of the material.
摘要:
The present invention provides methods and materials useful delivering liquids, including liquids comprising nucleic acid molecules into cells. In particular, the present invention provides methods for delivering saline solution, exogenous compositions, and isolated vectors to kidney cells, using the renal vein as a guide and under hydrodynamic pressure. The delivery methods and materials herein are useful to research, prognose, ameliorate symptoms of kidney injury, and treat kidney pathologies.
摘要:
This invention relates to improvements to medical devices such as biosensors containing proteins such as oxidoreductases, for example oxidaseand/or peroxidase enzymes. More generally it relates to novel compositions containing proteins which are stabilised to ionising radiation.
摘要:
Provided are nanocomplexes having at least two different enzymes and a polymeric network anchored to at least one of the enzymes. In some embodiments, the activities of the enzymes catalyze a cascade reaction.
摘要:
The present invention relates to treatment of milk and milk products such as waste-milk with an enhanced lactoperoxidase system. The enhanced lactoperoxidase system is activated by the addition of a hydrogen peroxide source and an oxidizable agent, such as a halide to the milk to inactivate the bacterial pathogens. The enhanced lactoperoxidase system may be used alone or in conjunction with pasteurization to reduce or eliminate the bacterial load in milk products.
摘要:
A medicament for the treatment or prevention of a microbial infection or an associated condition in a low oxygen environment characterised in that the medicament includes an extended acting oxygen generating system.
