The present invention relates to the present invention provides novel recombinant protein produced from cholinesterase gene derived from Pseudomonas aeruginosa and the composition comprising the same for treating or preventing a neurological disease.

The invention relates to cyclic polypeptides derived from the C-terminus of acetylcholinesterase for use in treating or preventing cancer or metastatic disease.

A device and method for the rapid on-site detection of inhibitors of enzymes, such as acetylcholinesterase, is described wherein the device contains all reagents added to a sample pad containing dried releasable enzyme creating a reaction mixture wherein inhibitor deactivates the enzyme, while said reaction mixture travels via a longitudinal membrane to a distal porous pad containing a substrate for the enzyme. The reaction of the enzyme and the substrate results in a product that can generate a measurable signal such as color, fluorescence or luminescence to serve as a reporter. Signal that is generated at this reaction zone is inversely proportional to inhibitor concentration in the test sample. A device containing two such strips, one for a test sample, the other for a negative control fluid as an onboard comparator is described. A purpose-built reader or an illuminating device, such as, containing an incandescent light source, a diode, a UV light source or any other illumination source that is suitable for the reporter or mere visualization is used to determine the level of reporter.

The present invention provides a method form making a composition of nanoparticles comprising a biological mimetic base component that forms the structure of the nanoparticle. By interacting with the functional groups of the base component, the half-life of a bioactive molecule is extended.

Described herein are oxime compounds capable of inactivating a nerve agent, blood brain barrier (BBB)-penetration, and/or reactivation of nerve agent-inhibited acetylcholinesterase (AChE) and related methods, systems and compositions for inactivation of one or more nerve agents, therapeutic and/or prophylactic treatment of an individual, and/or decomposition of nerve agent for decontamination.

The invention relates to novel peptides, compositions, therapies and methods for treating neurodegenerative disorders, for example Alzheimer's disease.

The present disclosure provides an in vitro mammalian cell that is genetically modified to provide for enhanced production of adeno-associated virus (AAV) virions. The mammalian cells can be used to produce AAV virions, e.g., recombinant AAV virions that include a heterologous nucleic acid encoding a gene product; the present disclosure thus provides methods for producing an AAV virion, which may be a recombinant AAV virion.

A cyclic polypeptide, derivative or analogue thereof, comprising an amino acid sequence derived from the C-terminus of acetylcholinesterase (AChE), or a truncation thereof.

This disclosure provides a method and a kit for pesticide detection. By expressing acetylcholinesterases on cell surface, rapid pesticide screening, identification and quantification of pesticides or insecticides may be achieved.
