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.

Unique Method Of Predicting Response To Immunotherapy For Human Melanoma

This invention describes a technical advancement in human tissue digestion that allows for the successful profiling of tumor infiltrating lymphocytes (TILs) by flow cytometry.  Using this digestion method, UCSF researchers were able to determine that patients with 30% or more TILs with high expression of biomarkers PD-1 and CTLA-4 are likely to respond to anti-PD-1 cancer immunotherapy.

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. The degree to which a molecule is modified and at what positions dictates how that structure interacts within the body. UCI researchers have developed novel methods of detecting and mapping serine and threonine sulfonation of peptides and proteins.

Hydrogel for Improved Burn Wound Healing

Background: The US spends $25B alone on wound treatment of burns. The wound treatment market is projected to grow to $18.3B in just 4 years. Current treatments have been unsuccessful in fostering proper wound healing safe from infections. Not only do they have low efficacy, but they are very expensive to produce. The most commonly used wound dressing is a hydrogel. Hydrogels reduce pain and healing time, promotes cell proliferation and collagen deposition, and is the most appropriate for burn wounds.  Brief Description: UCR researchers have developed a novel formulation that can be embedded into a hydrogel to significantly improve wound healing. Through successful conjugation of a peptide and polymer, stability and longevity have been enhanced. Their formulation induced a 3-fold increase in density of newly formed microvessels, greatly improving tissue quality.

Diagnostic and Screening Methods for Atopic Dermatitis

Atopic dermatitis (AD) is a chronic itch and inflammatory disorder of the skin that affects one in ten people. Patients suffering from severe AD eventually progress to develop asthma and allergic rhinitis, in a process known as the “atopic march.” Signaling between epithelial cells and innate immune cells via the cytokine Thymic Stromal Lymphopoietin (TSLP) is thought to drive AD and the atopic march. TSLP is up regulated in atopic dermatitis patients and is thought to act on immune cells to trigger atopic dermatitis. Scientists at UC Berkeley discovered that TSLP also activates a subset of sensory neurons to signal itch by acting on TSLPR, which signals to TRPA1. They demonstrated that sensory neurons that transmit itch signals in AD are the only instance of signaling between TSLPR and TRPA1 in the same cell type. Therefore, blocking the signaling between TSLPR and TRPA1 is a novel and specific target for therapeutics for itch in atopic dermatitis. They also discovered that the Orai I/Stim I pathway triggers expression and secretion of TSLP. This pathway has never been directly demonstrated in human primary keratinocytes and has never before been linked to TSLP. Decreasing expression of Orai I or stim I using siRNA, or the downstream transcription factor, NFATc I, significantly attenuates TSLP secretion, as proven in mice studies. Thus inhibition of Orai I/Stim I/NFATc I signaling pathway is a novel target for therapeutics for itch in atopic dermatitis.

Transposon Vector for Vertebrate & Invertebrate Genetic Manipulation

Background: Therapeutic delivery of genes is a rapidly evolving technique used to treat or prevent a disease at the root of the problem. The global transgenic market is currently $24B, growing at an annual projected rate of 10%. Currently, a variation of this technique is widely used on animals and crops for production of desirable proteins, but this is a heavily infiltrated market. Thus, entering the gene therapy segment is more promising and would enhance the growth of this industry.  Brief Description: UCR Researchers have identified a novel transposon from Aedes aegypti mosquitoes. This mobile DNA sequence can insert itself into various functional genes to either cause or reverse mutations. They have successfully developed a transposon vector system that can be used in both unicellular & multicellular organisms, which can offer notable insight to improve current transgenic technologies as well as methods of gene therapy.

Compound for the Prevention Of Rosacea Inflammation

Rosacea is a chronic skin condition characterized by recurrent episodes of flushing, erythema, vasodilation, telangiectasia, edema, papules, pustules, hyperplasia, fibroplasia, itching, burning, pain, and skin tightness. Symptoms of rosacea are exacerbated by sun exposure, hot weather, immersion in hot water, high humidity, sweating, exercise, emotional stress, and spicy food. The skin condition usually begins between the ages of 30 to 50 and occurs more frequently in women than men. An estimated 16 million people are affected by rosacea inflammation in the United States. Oral and topical antibiotics are usually the first line of treatments prescribed for rosacea patients. However, they can cause serious side effects in some patients and do not address the underlying condition. Topical application of steroids may also help alleviate the symptoms, but it can also aggravate the condition. In addition, long term treatments can be inconvenient, lasting for as long as two years.

Inflammation Induction and Tissue Repair

Inflammation is an important response for resisting infection and repairing damage. Under circumstances such as cancer or infectious diseases, stimulation of the inflammatory response is therapeutic. It is unclear why the existing adjuvant therapies tend to be more effective in the treatment of some disease, such as breast and colon cancer, than others. This invention identifies additional ways to stimulate the immune response and induce inflammation in order to accelerate repair of disease-related tissue injury.

New Matrices for Cosmetic and Reconstructive Surgery

Decellularization of tissues has recently emerged as a major player in the field of regenerative medicine and offers the possibility of producing a scaffold that closely mimics the physical and chemical cues seen by cells in vivo. Materials produced in this manner often have positive angiogenic and chemoattractant properties. Despite the availability of several injectable materials, there has yet to be identified an engineered material that avoids immune complications and encourages new fat formation. And while many tissues share similar extracellular matrix (ECM) elements, each tissue has its own complex composition and concentration of chemical constituents, which are known to regulate numerous cell processes including attachment, survival, migration, proliferation, and differentiation. There continues to be a need for improved compositions for loose connective tissue repair, regeneration and cell culturing that will closely mimic the complexity of natural adipose extracellular matrix.

New Light Emission Detection Method Enables High Resolution Optical Imaging of Biological Tissue.

Researchers at the University of California, Irvine have developed a novel method for capturing cellular resolution images of biological tissue at depths of up to several millimeters. Conventional fluorescence detection methods utilize microscope objectives for emission light collection, a less effective approach that is only capable of imaging up to one millimeter deep.To improve upon this standard, the UC researchers minimized light losses by optimizing the system's excitation and detection optics. This new novel method increases the ability to capture cellular resolution images of biological tissues at depths 3x that of previously used methods. The improved method is capable of imaging up to 3 millimeters deep, while previous methods were only capable of depths up to 1 millimeter.
