Novel Nanoliposomal Nitroglycerin Formulation for Cardiovascular Therapies

    To address this major limitation, investigators at UCR have developed a nanoliposomal formulation of NTG, which achieves a 70-fold increase in the anti-inflammatory effect of NTG when compared to NTG. This increase in potency allows lower doses to be effective, which could mitigate the common issues seen with high clinical doses of NTG viz. loss of NTG sensitivity and endothelial toxicity. Fig. 1 Adhesion of U937 monocytes to NO-deficient (L-NIO-treated) ECs is significantly blocked by treating ECs with 5 ug/ml nanoliposomal nitroglycerin (NTG-NL). L-NIO is a selective eNOS inhibitor.  Remarkably, this anti-inflammatory dose of NTG in nanoliposomes is 70-fold lower than the dose of free NTG (5uM) required to achieve a similar effect

Patient Initiated Controlled Analgesic Remote Dispenser (PICARD)

Misuse, abuse, and diversion of prescription drugs are a major health problem in the United States, where opioid overdose caused more deaths than suicide and car accidents combined in 2013. The inventors at UCI have developed the Patient Initiated Controlled Analgesic Remote Dispenser (PICARD) system that increases patient adherence to prescribed drug protocols by requiring authentication (such as a fingerprint), dispensing single pills, and recording each event.

A General Method For Designing Self-Assembling Protein Nanomaterials

UCLA researchers in the Department of Chemistry & Biochemistry have developed a novel computational method for designing proteins that self-assemble to a desired symmetric architecture. This method combines symmetrical docking with interface design, and it can be used to design a wide variety of self-assembling protein nanomaterials. 

Configurations for Integrated MRI-linear Accelerators

Researchers at Stanford and University of California, Berkeley, have developed an integrated MRI-Linac hybrid system that can increase the efficacy of image-guided radiotherapy (IGRT). This system allows more aggressive treatment strategies that employ dose escalation, tighter geometric margins and sharper dose gradients which can improve clinical outcomes. This radiotherapy treatment apparatus includes a treatment beam (charged by Linac, particle, proton, or electron beam), a magnetic field disposed parallel collinear to the treatment beam, and a target that is disposed along the treatment beam. MRI is ideal for IGRT, however, there is magnetic field and RF interference between the linear accelerator and MRI scanner. The configurations of this system overcome this issue.

Enhanced Cell/Bead Encapsulation Via Acoustic Focusing

The invention consists of a multi-channel, droplet-generating microfluidic device with a strategically placed feature. The feature vibrates in order to counteract particle-trapping micro-vortices formed in the device. Counteracting these vortices allows for single particle encapsulation in the droplets formed by the device and makes this technology a good candidate for use in single cell diagnostics and drug delivery systems.

A Micro/Nanobubble Oxygenated Solutions for Wound Healing and Tissue Preservation

Soft-tissue injuries and organ transplantation are common in modern combat scenarios. Organs and tissues harvested for transplantation need to be preserved during transport, which can be very difficult. Micro and nanobubbles (MNBs) offer a new technology that could supply oxygenation to such tissues prior to transplantation, thus affording better recovery and survival of patients. Described here is a novel device capable of producing MNB solutions that can be used to preserve viability and function of such organs/tissue. Additionally, these solutions may be used with negative pressure wound therapy to heal soft-tissue wounds.

These properties include uniform sizes and shapes, biodegradability, and multiple sets of functional handles for chemical manipulation. Intact virus nanoparticles have been functionalized for applications in drug delivery in vivo, however, the injection of replication-competent viruses into subjects have limited their clinical appeal. The development of spherical and rod-shaped virus nanoparticles has in both cases resulted in differential tumor accumulation, demonstrating the need to further expand the shape library of protein nanomaterials. However, expressing non-spherical virus-based protein nanomaterials without the genetic material that functions as a backbone to the assembly architecture can lead to significant challenges including poly-diversity in size and shape, and change in assembly behavior in response to different conditions such as pH and ionic strength.   UC Berkeley researchers have developed a self-assembling nanoscale disk derived from a mutant of a recombinantly expressed viral coat protein. The disks display highly stable double-disk assembly states. The researchers functionalized the disks with the chemotherapy drug doxorubicin (DOX) and further modified the disks for improved solubility.  The functionalized disks displayed cytotoxic properties similar to those of DOX alone when incubated with U87MG glioblastoma cells, but the unmodified disks did not cause any cytotoxicity.

Novel method for detection of O-Sulfonation sites on post-translationally modified proteins

Sulfonation of proteins and carbohydrates plays an important role in signaling, transport, and metabolism in the body.

UCI researchers have developed novel methods of detecting and mapping serine and threonine sulfonation of peptides and proteins.
