A Point Of Care Method To Detect Covid19 Infected And Immune Patients For Pennies

The emergence of a novel coronavirus disease (COVID-19) in late 2019 has caused a worldwide health and economic crisis. Determining which members of the population are infected is key to re-opening of schools, universities, and non-essential businesses. To address this, researchers at UCI and UIC have developed an inexpensive point of care test using RNA aptamer technology for detecting COVID19 infected and immune patients that can be taken at home like a pregnancy test.

Particle-Sorting Device for Isolation, and Enrichment of Particles at Ultra-Low Concentrations

Researchers at UCI have developed an innovative method for assesses coronary artery stenosis and microvascular disease that is both accurate and non-invasive.

The Uro-Wheel

Though guidewires are a common part of many endoscopic procedures as they help the scope reach its desired organ successfully, they are often difficult to maneuver due to their flexible and slippery construction. To combat this and assist physicians in rapid and effective endoscopic placement, researchers at UCI have developed a novel device which, by a simple turn of a finger wheel, allows the guidewires to be automatically and controllably advanced and retracted.

Personalized Oncology Drug Efficacy Monitoring Chip

This versatile device features real-time, continuous screening of patient samples without the need for expensive labeling reagents, large sample sizes, or bulky readout equipment.

Early Detection Of Diabetic And Decubitus Ulcers

Pressure ulcers and diabetic foot ulcers are a pervasive and expensive health care challenge. They are debilitating and can significantly impair quality of life, as they are associated with loss of pain sensation and disordered circulation. The gold standard to preventing pressure ulcers include regular patient  turning/repositioning. However, there are relatively few tools for molecular-level insight into when to reposition and who to reposition.

Development of Biomarker Panel and Methods to Monitor Kidney Health

It has been shown that intensive BP lowering results in higher blood creatinine, which is typically indicative of decreased kidney function, thereby causing physicians concern that the patient is suffering from kidney damage. However, an increase in blood creatinine levels may also be due to changes in blood flow, a hemodynamic effect that is benign to the patient. Sodium glucose transporter 2 (SGLT2) inhibitors are a relatively new class of drugs for treating type 2 diabetes, which have been shown to result in lower risk for progression to dialysis in long-term follow-up. However, when patients first begin a therapeutic regimen of SGLT2 inhibitors, they typically experience an acute change in blood flow to the kidney, which results in a rise in serum creatinine. This causes concerns to practitioners that the drug may be harming the kidneys, rather than being beneficial long term. While some patients may indeed experience intrinsic kidney damage due to marked reductions in blood flow, resulting in cessation of SGLT2 inhibitor therapy and the benefit associated therewith, there is currently no way to differentiate between these two patterns of creatinine change. Thus, a need exists for diagnostic test to differentiate intrinsic kidney damage from hemodynamic changes in patients taking SGLT2 inhibitors for diabetes mellitus.

New Non-Invasive Markers To Assess Efficacy Of Anti-Integrin Therapies

Inflammatory bowel disease is a chronic disease, which affects the lower bowel parts or the entire GI tract, causing symptoms like abdominal pain, diarrhea, fever and weight loss. An estimated two million people in North America suffer from IBD seemingly caused by an overactive mucosal immune system. Crohn’s Disease and ulcerative colitis (UC) are the major groups of inflammatory conditions that make up IBD and are incurable, serious and chronic organic diseases of the intestinal tract.   Recently, anti-integrin monoclonal antibodies have been approved by the FDA as therapeutic agents for treatment of IBD and there are a number of phase three clinical trials ongoing using monoclonal antibody therapy. The immune system responds to the inflammation that is part of the immunopathology of IBD and acts by recruiting inflammatory cells to the intestinal lesions.  Intergrins, specifically alpha 4-β7, plays a key role in mediating leukocyte trafficking from the circulation to the vascular endothelial barrier in gut-associate lymphoid tissue with the ligand MAdCAM-1. The use of anti-integrin therapy targeting alpha 4-β7 reduces the number of immune cells to the gut endothelium. However, the precise identity of the cell subsets depleted from the intestinal lamina by these anti-integrin drugs have not been identified. Thus, there is an unmet need to further develop tools that allow for the identification of the critical effector cell subsets targeted by these drugs in the intestine.

Development of Methods and Assay for Measurement of Total Oxidized Phospholipid (OxPL)

Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in the United States. It can be broadly sub-classified into nonalcoholic fatty liver (NAFL), which is thought to have minimal risk of progression to cirrhosis, and nonalcoholic steatohepatitis (NASH), which is thought to have an increased risk of progression to cirrhosis. The current diagnostic gold standard for differentiating whether a patient with NAFLD has NAFL versus NASH is liver biopsy. However, liver biopsy is an invasive procedure, which is limited by sampling variability, cost, and may be complicated by morbidity and even death, although rare. Accurate, non-invasive, biomarkers for the detection of liver disease and liver disease progression e.g., progression to NASH, are currently also not available.

Monoclonal Antibodies Specific to Canine PD-1 and PD-L1

Researchers at the University of California, Davis have developed monoclonal antibodies with multiple applications relevant to canine PD-1 and PD-L1.

Imaging Modalities and Methods for Enhanced, Label-free Histopathology During Surgery

Researchers at the University of California, Davis have developed new techniques capable of producing near real-time tissue analysis with quality and accuracy attributes comparable to traditional Haemotoxylin and Eosin (H&E) histopathology methods.

Detecting Cardiovascular Disease Using Noninvasive Imaging of the Eye

Cardiovascular disease is the leading cause of mortality and disability worldwide. It is also prevalent, affecting 9% of the population over 20 years of age. Patients with cardiovascular risk factors can reduce their risk of developing catastrophic cardiovascular events such as heart attack and stroke through lifestyle modification and medications. Unfortunately for many, the disease may go undiagnosed until the occurrence of serious events. Identifying biomarkers of subclinical ischemia can help identify patients with occult cardiovascular disease.

Blood Flow Velocimetry via Data Assimilation of Medical Imaging

Cardiovascular disease (CVD) is a tremendous burden on the population in terms of morbidity and mortality, as well as on the healthcare system in terms of cost. Various forms of CVD including atherosclerosis, valve and ventricular dysfunction, aneurysms, and thrombogenesis can be identified by measuring localized abnormalities in blood flow. Accordingly, the ability to noninvasively interrogate physiological flows enables identification and diagnosis of disease, monitoring of the effects of therapy, and research on the hemodynamic nature of CVD and its associated interventions. In the clinic, blood flow measurements are primarily made using phase contrast magnetic resonance imaging (PC-MRI) and ultrasonic color Doppler imaging. Certain limitations of these techniques for patients who have contraindications or suffer from arrhythmias, as well as the desire for volumetric flow information necessitate the development of a new modality for blood flow velocimetry.

Use of UBA7 and its Regulated Genes as Novel Biomarkers in Treating Human Cancers

Human Ubiquitin-like modifier-activating enzyme 7 (UBA7) is a protein is involved in protein modification, specifically involving the pathway for protein ubiquitination. The modification of proteins with ubiquitin is an important cellular mechanism for targeting abnormal or short-lived proteins for degradation. Ubiquitination involves at least three classes of enzymes: ubiquitin-activating enzymes, or E1s, ubiquitin-conjugating enzymes, or E2s, and ubiquitin-protein ligases, or E3s. UBA7  encodes a member of the E1 ubiquitin-activating enzyme family. Moreover, ubiquitination and ubiquitin-like post-translational modifications (PTMs) regulate activity and stability of oncoproteins and tumor suppressors. Biomarkers are very important as companion diagnostic tools to guide clinical practice in treating human cancers, especially for targeted therapies. In the era of precision medicine, it is important for development companion diagnostic tools that can guide clinical practice for treating human cancers using targeted therapies.

Multi-Sensing Intravascular Catheter to Prevent Heart Attack or Stroke

UCLA researchers in the Department of Medicine have developed a multi-functional catheter that combines different sensing capabilities to improve the detection of unstable plaques.

Breast Milk Biomarkers for Child Chronic Health Disorders

Autism Spectrum Disorder (ASD) is a developmental disorder associated with difficulties in social interaction and communication as well as repetitive behavior. ASD is thought to be the result of genetic and environmental factors that affect approximately 1 in 59 children in the US, and 25 million people worldwide. The current method of diagnosis for ASD involves evaluations and tests performed by a team of specialists.  The latest forms of diagnosis can detect ASD as early as 18 months. However, more standard methods take until 4 years of age before the diagnosis of ASD is confirmed. There remains an unmet need to develop a reliable and accurate diagnostic methods for early detection for a child at risk with chronic and/or developmental disorders, such as ASD, so that an early intervention measures will be applied before the first symptoms appear.

A Method to Measure Perceptual Thresholds

UCLA researchers in the Department of Psychology have developed a method to accurately measure a patient’s perceptual (visual, auditory, etc.) threshold unaffected by patient response bias.
