Endoscopic ultrasound-guided fine needle injection

Endoscopic ultrasound-guided Fine Needle Aspiration (EUG-FNA) is a method by which tissue biospies are collected using a needle tip guided by real-time ultrasound imaging. UCI physicians propose a novel utility for EUS-FNA with enclosed fine needles that would allow the sterile injection of dyes, drugs and therapeutics to specific anatomical sites.

Novel Methods for Studying Ceramide In Vivo and Inducing Ceramide-Induced Apoptosis

Mammalian cells synthesize thousands of distinct lipids, yet the function of many of these lipid species is unknown. Ceramides are a chemically diverse class of sphingolipids that have critical roles in a wide range of biological pathways, but poor cell permeability and lack of selectivity in endogenous synthesis pathways have hampered direct study of their effects. Despite their high biological interest, ceramides have been difficult to study because of their impermeability to the cell membrane.

In Vitro Reconstituted Plant Virus Capsids For Delivering Rna Genes To Mammalian Cells

UCLA researchers in the Department of Chemistry & Biochemistry have developed a method for using in vitro reconstituted plant virus-derived vectors to package and deliver RNA genes for targeted delivery of vaccines, MRI contrast agents, and therapeutic proteins in RNA form.

Massively Parallel High Throughput Single Cell Electroporation (MSEP)

UCLA researchers in the Department of Mechanical and Aerospace Engineering have developed a novel massively parallel, single cell electroporation platform (MSEP) that is high throughput, efficient, and maintains cell viability.

Preventative Trackable Anticoagulants for Atrial Fibrillation Treatment

Researchers at the University of California, Davis have developed a process to localize anticoagulation drugs for treatment of inflammation and atrial fibrillations.

Metabolite-Responsive Hybrid Biomaterials

Researchers have developed a “smart” biomaterial for drug delivery systems capable of responding to signature cancer metabolite concentrations in tumor environments. This response triggers the release of encapsulated drugs at a specific tumor target.

Protein Nanoparticles For Cancer Immunotherapy

Though new therapeutics for the treatment of cancer are constantly being developed, they often show low efficiency for long-term remission, adverse side effects, and low immune response. Scientists at UCI have found a way to combat these issues with a combination therapy delivered by nanoparticle of both a vaccine, to prime the immune system, and a checkpoint inhibitor to shut down anti-cancer immune responses. This has been shown to prolong survival and promote immune response and immunological memory related to long-term survival.

Use of a Radiation Detector that Combines Virtual Frisch Grid and Cerenkov Readouts

Researchers at the University of California, Davis have developed a radiation detector for high energy photons that employs a transparent semiconductor with a high index of refraction to combine benefits of Virtual Frisch Grid devices and the readout of Cerenkov light.

UCLA researchers have developed a novel microporous annealed particle (MAP) scaffold that acts as both a tissue growth scaffold and an immune modulatory system. The technology permits continuous, time-encoded, modulation of the immune system delivered injection/implantation of fabricated scaffold, comprised of the MAP gel technology.

Disulfide Bioconjugation

UCLA researchers in the Department of Chemistry and Biochemistry have proposed a one-step radical mechanism for disulfide bioconjugation that overcomes many concerns associated with the free cysteine residues that result from current bioconjugation techniques.

Bacteriotherapy against Propionibacterium Acnes for the Treatment of Acne Vulgaris

Reduction in Propionibacterium acnes (P. acnes) survival correlates with clinical improvement of acne in patients. Systemic antibiotics have been used to treat acne for several decades and are still widely prescribed for acne patients. Topical antibiotics are also helpful, and the oxidizing agent benzoyl peroxide (BPO) has been one of the most frequently used topical medications for acne treatment. Topicals are often used as the first line treatment for patients suffering from mild to moderate acne. However, current antibiotic treatments have major drawbacks. Systemic antibiotics nonspecifically disrupts microbial ecosystem and promote antibiotic resistance. Topical antibiotics are very poor at killing P. acnes on the skin surface, therefore there is a current need for alternative methods for treatment.

Preparation Of Functionalized Polypeptides, Peptides, And Proteins By Alkylation Of Thioether Groups

UCLA researchers in the Departments of Chemistry, Physics, and Bioengineering, led by Dr. Tim Deming of the Bioengineering Department, have developed new methods for adding different functional groups on polypeptides.  The UCLA researchers have used this method to create a platform to create and modify nanoscale vesicles and hydrogels for use in nanoscale drug delivery particles, injectable drug depots, imaging and detection, industrial biomaterials, and wound management.

New Form Of Hybrid Materials

Advances in science are driven by new discoveries which can pave the way to new create new research directions. For example, crystals by the nature of their order in three-dimensional space, cannot flex or expand, but with the integration of macromolecular ferritin crystals with hydrogel polymers can change their dimensions.
