This invention discloses methods and composition to form biodegradable polymer implant arrays in the live tissue. Artificial cavities are created in the live tissue by using laser ablation, oscillating needle, microneedle array and other methods. The cavities are then filled with biodegradable polymer solution. The solvent in the polymer solution is dissipated in the tissue to form a biodegradable polymer implant in artificial cavities. The cavities and implants formed are arranged to form of an array of implants. The biodegradable polymer in the cavity can also be loaded with drug to form biodegradable drug delivery array in the live tissue.

The field of the disclosure relates generally to cancer cell destruction and, more specifically, to cancer cell destruction by photo-magnetic irradiation mediated multimodal therapy using smart nanostructures.

A method of therapy for a tumor or other pathology by administering a combination of thermotherapy and immunotherapy optionally combined with gene delivery. The combination therapy beneficially treats the tumor and prevents tumor recurrence, either locally or at a different site, by boosting the patient's immune response both at the time of original therapy and/or for later therapy. With respect to gene delivery, the inventive method may be used in cancer therapy, but is not limited to such use; it will be appreciated that the inventive method may be used for gene delivery in general. The controlled and precise application of thermal energy enhances gene transfer to any cell, whether the cell is a neoplastic cell, a pre-neoplastic cell, or a normal cell.

The blood-brain barrier (BBB) excludes most drugs and poses a significant challenge to treat brain diseases. Current methods for BBB opening yield modest outcomes in clinical applications due to safety and toxicity. This disclosure relates to methods of optically opening the BBB by laser excitation of tight-junction targeted nanoparticles to induce BBB transient opening. The excitation of plasmonic nanoparticles produces localized effects such as nanoscale heating and photomechanical force leading to BBB transiently opening to allow macromolecules across it. The safe and predictable platform for brain drug delivery will improve therapies for brain disease such as cancers, infections and neurologic disorders.

The present disclosure provides phospholipid-containing compounds, pharmaceutical compositions and microspheres that exhibit high affinity for mineralized metals. The present disclosure also provides strategies for using said compounds, compositions and microspheres in the treatment of nephrolithiasis or kidney stone disease, and methods of manufacturing and preparing said compounds and compositions.

Cancer treatment and imaging methods using thermotherapy and drug delivery are disclosed herein. In one embodiment, the method comprises the steps of administering a plurality of antibody or aptamer-conjugated nanoparticles, liposomes, and/or micelles containing a medication and/or gene to a patient in need thereof so as to target a tumor in the patient, at least some of the antibody or aptamer-conjugated nanoparticles, liposomes, and/or micelles attaching to surface antigens of tumor cells of the tumor so as to form a tumor cell/nanoparticle/liposome/micelle complex; and heating the antibody or aptamer-conjugated nanoparticles, liposomes, and/or micelles using an energy source so as to raise the temperature of the tumor cell/nanoparticle complex, micelle complex, and/or liposome complex, thereby releasing one or more medications from the antibody or aptamer-conjugated nanoparticles, liposomes, and/or micelles, and damaging one or more tumor cell membranes at the tumor site.

The present invention relates to a method for increasing the blood-brain barrier permeability, and more particularly, to a method for increasing the blood-brain barrier permeability, the method including: (S1) a step of delivering a nanogenerator carrying a nitric oxide (NO) donor to a site adjacent to the blood-brain barrier; (S2) a step of delivering a first triggering stimulus to an area where the nanogenerator has been delivered so as to release nitric oxide from the nanogenerator; and (S3) a step of allowing the released nitric oxide to activate matrix metallopeptidase-9 (MMP-9) and inducing the activated MMP-9 to weaken the tight junction between a cerebrovascular endothelial cell and another cerebrovascular endothelial cell.

Methods and apparatus are provided for applying an fragment of a neurotoxin such as the active light chain (LC) of the botulinum toxin (BoNT), such as one of the serotype A, B, C, D, E, F or G botulinum toxins, via permeabilization of targeted cell membranes to enable translocation of the botulinum neurotoxin light chain (BoNT-LC) molecule across the targeted cell membrane to the cell cytosol where a therapeutic response is produced in a mammalian system. The methods and apparatus include use of catheter based delivery systems, non-invasive delivery systems, and transdermal delivery systems.

The present disclosure provides biophotonic compositions, kits and their uses. In particular, the biophotonic compositions of the present disclosure arc substantially resistant to leaching such that low amounts of chromophores present in the biophotonic composition leach out of the composition. The biophotonic compositions and their uses are useful for promoting repair of non-healing wounds.

The present disclosure provides imaging agents that are useful for the detection and evaluation of heart conditions, such as myocardial infarction. Upon activation, the imaging agents of the present disclosure may be detected using an ultrasound imaging device.
