Function of Epirubicin-Conjugated Polymeric Micelles in Sonodynamic Therapy

In conclusion, drug-conjugated micellar nanoparticles are more desirable for SDT because of accelerated ROS production and drug protection from ROS. Furthermore, a combination of NC-6300 and TP-HIFU is useful for minimally invasive cancer therapy with cooperative effects of HIFU-derived features, antitumor activity of EPI, and increased ROS generation to cause damage to cancer cells.

Abstract High intensity focused ultrasound (HIFU) is widely used in medical practice, including cancer therapy. Also this approach is promising for remote release of encapsulated drugs in various other biomedical applications where local treatment is needed. Our approach underpins the minimization of HIFU impact on possible degradation of biological tissues and expand the use of HIFU in the controlled release of encapsulated drugs. We demonstrated the efficient ultrasound-induced release of labeled protein (Cy7-BSA) from elaborated nanocomposite microcapsules in vitro an in vivo. The capsule fabrication was done u...

CONCLUSIONS: Targeted MRI/TRUS fusion-guided focal HIFU allows local tumor ablation, but is not free from limitations. The procedure has good functional outcomes and a quick recovery. Multicenter trials with more patients are required to determine the procedure´s role in the prostate cancer therapy algorithm. PMID: 30093211 [PubMed - as supplied by publisher]

Abstract  Theranostics is a term used to describe the combination of diagnostic and therapeutic functions in a single agent. Ultrasound, for example, is a good tool for theranostics due to its multi-potency as both a diagnostic tool using sonography, and as a therapeutic, i.e., by high intensity focused ultrasound (HIFU). Likewise, microbubbles and nanobubbles are not only used as contrast imaging agents, but also as enhancers of drug delivery. Recently, the combination of these bubbles with low intensity ultrasound has been utilized as an effective drug delivery system. We have implemented a similar technique b...

AbstractPurpose of ReviewProstate cancer is one of the most prevalent malignancies in males and treatment is not infrequently associated with substantial morbidity. As a result, there has been growing interest in alternative therapies for prostate cancer therapy including high-intensity focused ultrasound (HIFU) and focal cryoablation. Herein, we review the potential genitourinary sequelae of these therapies including incontinence and erectile dysfunction.Recent FindingsVarious studies have demonstrated that with improvements in delivery technique and technologies aimed at treatment of prostate cancer, the risks of urinary...

ConclusionsTemperature measurements using the echo-time-shift method might be useful for validation of treatment plan algorithms. This might also be a comparatively accurate, fast, and affordable method for laboratory and clinical quality assessment. Further research is necessary to improve filter algorithms and to extend this method to multiple foci and the usage of temperature-dependent tissue quantities. We used an analytical approach to investigate the uncertainties of temperature measurement. Different analysis variations are compared to determine temperature distribution and development over time.

ConclusionsWe developed an MRgFUS platform for small-animal treatments that robustly delivers accurate, precise, and controllable sonications over extended time periods. This system is an open source and could increase the availability of low-cost small-animal systems to interdisciplinary researchers seeking to develop new MRgFUS applications and technology.
