The present disclosure relates to compositions and methods of killing cells. In particular examples, the method includes contacting a cell having a cell surface protein with a therapeutically effective amount of an antibody-IR700 molecule, wherein the antibody specifically binds to the cell surface protein, such as a tumor-specific antigen on the surface of a tumor cell. The cell is subsequently irradiated, such as at a wavelength of 660 to 740 nm at a dose of at least 1 J cm.sup.−2. The cell is also contacted with one or more therapeutic agents (such as an anti-cancer agent), for example about 0 to 8 hours after irradiating the cell, thereby killing the cell. Also provided are methods of imaging cell killing in real time, using fluorescence lifetime imaging. Also provided are wearable devices that include an article of clothing, jewelry, or covering; and an NIR LED incorporated into the article, which can be used with the disclosed methods.

A composition and method directed to the treatment of bacterial infections is provided.

Antifibrinolytic agents/drugs are applied to the concussive area of a patient's brain to counter the activation of a fibrinolytic process in the concussive area. Various techniques are described for administering the antifibrinolytic agent.

A phosphor-containing drug activator activatable from a Monte Carlo derived x-ray exposure for treatment of a diseased site. The activator includes an admixture or suspension of one or more phosphors capable of emitting ultraviolet and visible light upon interaction with x-rays, wherein a distribution of the phosphors in the diseased target site is based on a Monte Carlo derived x-ray dose distribution. A system for treating a disease in a subject in need thereof, includes the drug activator and a photoactivatable drug, one or more devices which infuse the photoactivatable drug and the activator including the pharmaceutically acceptable carrier into a diseased site in the subject; and an x-ray source which is controlled to deliver the Monte Carlo derived x-ray exposure to the subject for production of ultraviolet and visible light inside the subject to activate the photoactivatable drug and induce a persistent therapeutic response, the dose comprising a pulsed sequence of x-rays delivering from 0.5-2 Gy to the tumor.

Several gastrointestinal and gynecological malignancies have the potential to disseminate and grow in the peritoneal cavity. The occurrence of peritoneal carcinomatosis (PC) has been shown to significantly decrease overall survival in patients. Treatment of residual microscopic disease remains a challenge with new anticancer modalities development. Now, the inventors propose an innovative therapeutic management of peritoneal carcinomatosis (PC) that is bio-inspired and tumor-targeted by engineering MSC-derived EVs to encapsulate a photosensitizer (mTHPC) for improved photodynamic therapy efficiency and safety. In this work, the inventors first evaluated the biodistribution of EVs-mTHPC in a murine PC model and highlighted superior accumulation of mTHPC in the tumor compared to other mTHPC formulations (free drug and liposomal one (Foslip®). The effectiveness of PDT mediated by mTHPC vectorized in EVs has then been evaluated in PC. In accordance with pharmacokinetics, the results revealed both an enhanced light-induced therapeutic efficiency in terms of tumoral cytotoxicity, safety for surrounding tissue after laser irradiation, immunomodulation and improved survival time. Thus, the present invention relates to mesenchymal stem cell derived extracellular vesicles loaded with at least one photosensitizer and uses thereof for the treatment of peritoneal carcinomatosis.
