Stable and durable polymeric microbubbles of a 1-10 μm size range are disclosed. The microbubbles are synthesized from the co-polymer poly lactic-co-glycolic acid (PLGA), which provides a plurality of PLGA microbubbles presenting diverse cavitation activities. The PLGA microbubbles are particularly suitable for cavitation enhancement purposes and are applicable in various clinical procedures such as ablation or enhancement of uptake of chemical or biological therapy in cells and tissue.

The utility of intrathecal delivery is limited by the poor brain and spinal cord parenchymal uptake of intrathecally delivered agents. A simple noninvasive transcranial ultrasound protocol is provided that significantly increases the brain parenchymal uptake of intrathecally administered drugs and antibodies. This protocol of transcranial ultrasound can accelerate glymphatic fluid transport from the cisternal space into the parenchymal compartment. The low intensity and noninvasive approach of ultrasound in this protocol underscores the ready path to clinical translation of this technique. This low-intensity transcranial ultrasound protocol can be used to directly bypass the blood-brain barrier for whole-brain delivery of a variety of agents. Additionally, this protocol is useful as a means to probe the causal role of the glymphatic system in the variety of disease and physiologic processes to which it has been correlated.

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.

An in-case stand for a musical instrument that supports a musical instrument in the open musical instrument case, such as a guitar, in an inclined position making the headstock and the neck readily accessible for string changes, cleaning or light maintenance.

Various methods, systems, and devices for treating tissue ablation are disclosed. Some embodiments disclosed herein pertain to methods of treating tumors, systems used for irradiating tissue and tumors with electromagnetic radiation, components and devices of that system, and kits for providing systems used for irradiating tissue and tumors with electromagnetic radiation. In some embodiments, the system provides sub-ablative infrared radiation that is absorbed by nanoparticles. In some embodiments, the nanoparticles absorb the radiation converting it into heat energy. In some embodiments, though the infrared radiation itself may be sub-ablative, the heat energy generated by the nanoparticles is sufficient to cause thermal coagulation, hyperthermia, and/or tissue ablation.

Acoustically activatable particles having low vaporization energy are disclosed. A particle of material includes a first substance that includes at least one component that has a boiling point below 25° C. at atmospheric pressure. A second substance, different from the first substance, encapsulates the first substance to create the particle. The particle has a core consisting of a liquid and is an activatable phase change agent. The second substance includes a polymeric brush layer to prevent aggregation and coalescence.

The present invention relates to ultrasound (US) mediated delivery of therapeutic agents, such as the delivery of a drug, gene, nanoparticle or radioisotope, using a bi-phasic microparticle system comprising gas microbubbles, emulsion microdroplets and clusters thereof. Thus, the present invention relates to a cluster composition and a pharmaceutical composition, and their use for delivery of therapeutic agents and as a contrast agent for ultrasound imaging. It further relates to methods for delivering such therapeutic agents and to the use of said compositions.

The invention provides microbeads comprising chitosan, a magnetic nanoparticle, and an agent, and methods for using such microbeads for the local delivery of biologically active agents to an open fracture, complex wound or other site of infection or disease.
