An “inverse” precipitation route to precipitate aqueous soluble species with copolymers as nanoparticles having a hydrophilic, polar core and a less polar shell is described.

Provided are methods of mitigating, reversing or eliminating in a subject one or more symptoms associated with cognitive impairment associated with amyloid deposits in the brain (e.g., olfactory dysfunction as a risk factor of dementia, mild cognitive impairment, Alzheimer's Disease) by detecting and targeting gram negative bacteria in the brain.

Disclosed herein are methods for improving a parameter of a protein-related process comprising providing a viscosity-reducing excipient compound selected from the group consisting of hindered amines, anionic aromatics, functionalized amino acids, oligopeptides, short-chain organic acids, and low molecular weight aliphatic polyacids, and adding a viscosity-reducing amount of the viscosity-reducing excipient compound to a carrier solution for the protein-related process, wherein the carrier solution contains a protein of interest, and carrier solutions comprising a liquid medium in which is dissolved a protein of interest, and a viscosity-reducing excipient, wherein the viscosity of the carrier solution has a lower viscosity that that of a control solution that is substantially similar to the carrier solution except for the presence of the viscosity-reducing excipient.

The present disclosure features compositions and methods for the treatment of bacterial infections, such as bacterial infections caused by bacterial cells residing within a host cell (e.g., a mammalian cell, e.g., immune cell, e.g., macrophage or dendritic cell). The compositions and methods include delivering antimicrobial agents to specifically target the intracellular compartment (endosome, phagosome, lysosome, or cytosol) in which the bacterial cell resides.

Multiblock polymer materials, methods of preparing, and using to separate proteins, nucleic acids, other biological or other biomolecules, compounds, or solutes, with high fluxes through electrostatic interactions where the self-assembled block polymer materials contain at least one of macro, meso, or micro pores, and at least some of the pores are isoporous, and at least one polymer block contains stationary electrostatic charge, or reactive functional groups to provide large surface areas that are charged in isoporous structure.

The invention encompasses formulations and methods for the production thereof that permit the delivery of concentrated protein solutions. The inventive methods can yield a lower viscosity liquid formulation or a higher concentration of therapeutic or nontherapeutic proteins in the liquid formulation, as compared to traditional protein solutions.

A drug, food and application of an anti-coronavirus infection, the drug or food containing lysozyme or a combination that comprises lysozyme; the lysozyme or a combination thereof can be used to prepare a drug for anti coronavirus infection and preventing or treating coronavirus-related diseases or symptoms, or food for assisting in anti coronavirus infection and assisting in preventing or treating coronavirus-related diseases or symptoms. The present disclosure has a good preventive and therapeutic effect on coronavirus infection or related diseases or symptoms thereof; in addition, the present application can accelerate the elimination of the virus in vivo, accelerate the speed of coronavirus nucleic acid tests in vivo turning negative, shorten the course of a patient's illness, effectively prevent and reduce the spread of coronavirus, and also has important social benefits and good application prospects.

Provided are compositions and methods for use in selectively killing one or more of C. perfringens, C. sordelli and C. histolyticum. The compositions include lysin PlyCP025, as well as catalytically active fragments thereof, and variants thereof that retain killing activity. Methods for reducing one or more of C. perfringens, C. sordelli or C. histolyticum bacteria are provide and involve contacting such bacteria with a composition that contains PlyCP025 or an enzymatically active fragment or variant thereof, which can be provided as recombinant polypeptides. The composition and methods are useful for human and veterinary purposes. Diagnostic approaches are also included by contacting a sample obtained or derived from an animal, with a recombinant polypeptide, and detecting binding of the polypeptide to bacteria in the sample if said bacteria that are bound to the polypeptide are present in the sample. The polypeptide may thus be detectably labeled to produce a detectable signal.

A stable composition obtained by enzymatic oxidation of a halide thiocyanate mixture, including at least one ion selected from the group of the I2SCN— ions and the I(SCN).sub.2— ions, the composition being free of hypothiocyanite ions. In an embodiment, the composition further includes iodine thiocyanate ISCN. This disclosure also relates to a method for preparing the stable composition and to the uses thereof.
