20220152092 · 2022-05-19 ·

Methoxy polyethylene glycol for use as a medicament, in particular in skin healing, wound healing and treatment of a microbial infection. A method for treating a medical device and/or implant to reduce or eliminate microbial contamination comprises applying a liquid formulation comprising methoxy polyethylene glycol. This invention relates to the novel discovery that methoxy polyethylene glycol, an inactive polymer with no known pharmacological effect, was able to come between microbes and a surface, removing the microbes or releasing the attachment or adherence of the microbes to the surface and thereby improving wound healing significantly, eliminating infections and colonies of microbes.

Mechanical method of maintaining narrow residence time distributions in continuous flow systems

Methods of maintaining narrow residence time distributions in continuous flow systems, particularly applicable to virus inactivation such as during a protein purification process. Fluid sample is introduced into an axial flow channel and caused to flow therein in discrete packets or zones to minimize residence time distribution and axial dispersion. Embodiments described herein obviate or minimize the need for using large tanks or reservoirs for performing virus inactivation during a protein purification process; reduce the overall time required for virus inactivation, and/or reduce the overall physical space required to perform the virus inactivation operation during a protein purification process, which in turn reduces the overall footprint for the purification process.

Non-invasive energy upconversion methods and systems

Products, compositions, systems, and methods for modifying a target structure which mediates or is associated with a biological activity, including treatment of conditions, disorders, or diseases mediated by or associated with a target structure, such as a virus, cell, subcellular structure or extracellular structure. The methods may be performed in situ in a non-invasive manner by placing a nanoparticle having a metallic shell on at least a fraction of a surface in a vicinity of a target structure in a subject and applying an initiation energy to a subject thus producing an effect on or change to the target structure directly or via a modulation agent. The nanoparticle is configured, upon exposure to a first wavelength λ.sub.1, to generate a second wavelength λ.sub.2 of radiation having a higher energy than the first wavelength λ.sub.1. The methods may further be performed by application of an initiation energy to a subject in situ to activate a pharmaceutical agent directly or via an energy modulation agent, optionally in the presence of one or more plasmonics active agents, thus producing an effect on or change to the target structure. Kits containing products or compositions formulated or configured and systems for use in practicing these methods.
