The present disclosure relates to systems and methods for determining the renal glomerular filtration rate or assessing the renal function in a patient in need thereof. The system includes a computing device, a power supply, one or more sensors, and at least one tracer agent that fluoresces when exposed to electromagnetic radiation. The electromagnetic radiation is detected using the sensors, and the rate in which the fluorescence decreases in the patient is used to calculate the renal glomerular filtration rate in the patient.

The present invention relates to a nanoformulated self-assembled pharmaceutical composition for photodynamic therapy. More particularly, the present invention is directed to a self-assembled pharmaceutical composition for photodynamic therapy comprising a photosensitizer, a ligand A which is separated at a specific pH range, and a ligand B of which surface charge changes at a specific pH range and a method for manufacturing the same.

To provide a polymer having a high ratio of the amount thereof present in a tumor to the amount thereof present in blood (hereinafter, sometimes abbreviated as a tumor/blood ratio).

The polymer has phosphorylcholine (derivative) as a side chain and has a dye (near-infrared dye) having absorption in the near-infrared wavelength region bound to the polymer.

To provide a compound having high TB and a contrast agent for optical imaging. The compound has a molecular weight of a specific range, the compound in which two polyethylene glycols are bonded to a specific cyanine pigment through a linker. The present invention provides a compound which has a high T/B and which can be used as a contrast agent capable of imaging a tumor portion with high contrast.

Provided is a polymeric micelle pharmaceutical preparation that can increase the ratio of contrast at tumor site to background contrast in a short period of time after administration of a lactosome and can suppress the ABC phenomenon so that the lactosome can be administered more than once within a short span. A branched-type amphiphilic block polymer comprising: a multi-branched hydrophilic block comprising sarcosine; and a hydrophobic block comprising polylactic acid. The branched-type amphiphilic block polymer, wherein the number of branches of the hydrophilic block is 3. A molecular assembly comprising the branched-type amphiphilic block polymer. The molecular assembly further comprising a linear type amphiphilic block polymer.

The present invention relates to a novel delivery system for delivering therapeutic agents into living cells, and more particularly, to novel chemical moieties that are designed capable of targeting and/or penetrating cells or other targets of interest and further capable of binding therapeutic agents to be delivered to these cells, and to delivery systems containing same.

The invention described herein pertains to folate-receptor targeted agents comprising therapeutic agents useful for the treatment of inflammatory disease, including folate-receptor targeted liposomes (folate-targeted liposomes) containing entrapped therapeutic agents and folate-receptor targeted dendrimers conjugated to therapeutic agents (folate-targeted dendrimer conjugates), useful for the treatment of inflammatory disease, including auto-immune disease, as well as to folate-targeted liposomes containing entrapped imaging agents and dendrimer conjugates conjugated to imaging agents, for use in the diagnosis and monitoring of treatment in such disease.

Prostate-specific membrane antigen (PSMA)-targeted PAMAM dendrimers (G4-PSMA) and their use for imaging or treating PSMA-expressing tumors or cells are disclosed.

Cyclooctene conjugates of therapeutic or diagnostic agents have improved aqueous solubility and can release the agents upon contact with a tetrazine-containing biomaterial. The cyclooctene conjugates provide site-selective delivery of agents at the location of the tetrazine-containing biomaterial in a subject. The compositions and methods have applications in the treatment of various diseases or conditions including cancer, tumor growths, and bacterial infections.

This disclosure relates to conjugates for targeting bacteria and related uses. In certain embodiments, the disclosure relates to methods of transferring a molecule of interest into bacteria comprising mixing bacteria with a non-naturally occurring conjugate under conditions such that the conjugate is transported across the bacterial cell wall. Typically, the conjugate comprises an oligosaccharide and a molecule of interest. In certain embodiments, the molecule of interest may be a tracer or an antibiotic.
