Researchers at the University of California, Davis have developed an innovative platform for creating genetically encoded fluorescent biosensors capable of 1) assessing the formation of GPCR homo and heterodimers, and 2) determining how dimerization impacts protomer conformation in response to ligands.The UC Davis IPN has developed a suite of ~24 biosensors based on GPCR dimers.Collectively called, dimerLights, these modular biosensors have the ability to identify novel dimeric drug targets and assess the impact of ligands on their conformations.In addition to the ~24 biosensors that UC Davis has already developed, the modular platform in principle can easily be adapted to enable the discovery and evaluation of broader GPCR homo/heterodimers than have been tested so far.

A novel non-invasive therapy combining pulsed laser and dual-frequency ultrasound for rapid and precise treatment of port-wine stains.

Prof. Changcheng Zhou and colleagues from the University of California, Riverside (UCR) have developed an antisense oligonucleotide to knockdown tsRNA-Glu-CTC, which is an abundant tsRNA in the liver and a critical regulator of cholesterol homeostasis. This specific tsRNA is cholesterol responsive and interacts with the master lipid regulator SREBP2. In vivo studies in mice demonstrated that the treatment reduces hypercholesterolemia and hepatic steatosis (fatty liver) in mice fed a high-cholesterol diet. This treatment is advantageous because it may open new therapeutic avenues for cardiometabolic conditions and liver disease.

Stability issues in membrane-free coacervates have been addressed with coating strategies, but these approaches often compromise the permeability of the coacervate. Researchers from UC San Diego have invented a facile approach to maintain both stability and permeability using tannic acid and then demonstrate the value of this approach in enzyme-triggered drug release. First, the researchers developed size-tunable coacervates via self-assembly of heparin glycosaminoglycan with tyrosine and arginine-based peptides. A thrombin-recognition site within the peptide building block results in heparin release upon thrombin proteolysis. Notably, polyphenols are integrated within the nano-coacervates to improve stability in biofluids. Phenolic crosslinking at the liquid-liquid interface enables nano-coacervates to maintain exceptional structural integrity across various environments. The UCSD scientists discovered a pivotal polyphenol threshold for preserving enzymatic activity alongside enhanced stability. The disassembly rate of the nano-coacervates increases as a function of thrombin activity, thus preventing a coagulation cascade. This polyphenol-based approach not only improves stability but also opens the way for applications in biomedicine, protease sensing, and bio-responsive drug delivery.

Researchers at UC Irvine have developed a novel biomaterial to heal and regenerate tissues for chronic wounds. The biomaterial, referred to as GelMA-AN, has immunomodulating properties engineered for complete incorporation into injured tissue while enhancing the regenerative healing activities of immune and stromal cells. It is based on a gelatin scaffold supplemented with Methacrylic Anhydride and immunomodulating apoptotic neutrophil cells. All components have high biocompatibility due to structural and biochemical similarities to the host wound environment. This combination of the hydrogel scaffold and apoptotic neutrophils has uncovered a wound healing mechanism that acts through immunomodulation to enhance regenerative healing. The mechanism works by modulating immune cells to drive them from inflammatory to healing activities that in turn stimulate stromal cells to repair the skin and regenerate health skin appendages such as vasculature.

Stroke is a leading cause of mortality and disability worldwide and the economic costs of treatment and post-stroke care are substantial. Every year, more that 14 million people are affected by stroke, and over 6 million stroke patients die from this condition and associated complications. 2-(2,3,5-trisubstituted phenyl)oxazole compounds potently inhibit 12/15-LOX. Hence, the compounds of this disclosure are advantageously useful to treat or prevent various disorders where 12/15-LOX is implicated in the pathology of the disorder (e.g.,stroke). 

The invention pertains to a prosthetic valve featuring a saddle-shaped annulus that synchronously transforms between concave and convex configurations, facilitating seamless opening and closure synchronized with cardiac cycles. Comprising leaflets and support elements, the valve mimics natural heart valve function, enabling effective blood flow regulation and offering versatile deployment options for cardiac and vascular applications.
