Polarization-Sensitive Optical Coherence Tomography Using a Polarization-Insensitive Detector

A polarization-sensitive optical coherence tomography (PS-OCT) is a common approach to non-invasively imaging in biomedical applications. The inventors have come up with a new way of creating a PS-OCT that is cheaper and simpler.

Use of inhibitors and cell based therapies to combat a fatal immune response in COVID-19

UC researchers sought to define the host immune response, the “cytokine storm” , that has been implicated in fatal COVID-19 using an AI-based approach. Over 45,000 publicly available transcriptomic datasets of viral pandemics were analyzed to extract a 166-gene signature. The signature was surprisingly conserved in all viral pandemics, including COVID-19, inspiring the nomenclature ViP-signature. A subset of 20-genes classified disease severity in respiratory pandemics. The ViP signatures pinpointed airway epithelial and myeloid cells as the major contributors of an IL-15 cytokine storm, and epithelial and NK cell destruction as determinants of severity/fatality. They also helped formulate precise therapeutic goals to reduce disease symptoms and severity. Thus, the ViP signatures provide a quantitative and qualitative framework for titrating the immune response in viral pandemics and may serve as a powerful unbiased tool in our armamentarium to rapidly assess disease severity and vet candidate drugs. 

The Vaccushield Aka Slacc (Suction-Assisted Local Aerosol Containment Chamber)

UCLA researchers in the Department of Anesthesiology and Perioperative Medicine have developed a device that can act as a protective barrier for healthcare workers from patients with contagious respiratory pathogens.

Development of a Thermal Endoscope for ENT Clinical Diagnostics

There is a clinical need for improved visual inspection for ENT diagnosis and surgeries. Endoscopy is required to access locations of ENT conditions. However, the assessment and identification of ENT abnormalities and pathologies remain challenging due to the difficult-to- reach ENT locations and the complex nature of the related pathologies. An imaging technique that could provide additional information, high contrast, and quantitative data about the patient condition will be useful, especially to assist ENT clinicians in diagnosis and surgeries and to avoid the need to resort to more expensive imaging techniques (e.g., CT scans, ultrasound imaging,MRI).

Portable Lung Assist Device

UCLA researchers have developed a portable integrated system and device that supports failing human lungs, allowing patients to move around without the assistance of another person.

Live Attenuated Vaccine Against Group A Streptococcus Infection

Streptococcus pyogenes (group A Streptococcus [GAS]) is a leading health and economic burden worldwide, with an estimated 700 million infections occurring annually. Among these are 18.1 million severe cases that result in over 500,000 deaths. Despite active research, a protective vaccine remains elusive, leaving antimicrobial agents as the sole pharmacological intervention against GAS. To date, penicillin remains a primary drug of choice for combating GAS infections. However, despite no apparent emergence of resistant isolates, the rate of treatment failures with penicillin has increased to nearly 40% in certain regions of the world. Due to the high prevalence of GAS infection and the decreasing efficacy of the available repertoire of countermeasures, it is critical to investigate alternative approaches against GAS infection. An emerging strategy for combating pathogenic bacteria involves targeting virulence. To avoid immune clearance, GAS expresses a wide variety of secreted and cell-associated virulence factors to facilitate survival during infection. Despite decades of inquiry into the role and regulation of GAS virulence factors, the function and potential importance of many proteins involved in pathogenicity remain unknown.

A Fully‐automated Deep Learning System (software code) for the Detection, Prognosis, and Visualization of Pulmonary Disease.

The majority of state‐of‐the‐art lung segmentation algorithms in the literature do not simultaneously segment lungs, lung lobes, and airway in a single algorithm. Additionally, automated algorithms typically perform the segmentation task on a series of 2D slices, which can reduce segmentation accuracy of anatomical structures (i.e. lung lobes) that may require contextual information across all three spatial dimensions. Many existing algorithms also have not been validated on chest CTs across a wide variety of conditions to evaluate algorithm generalizability. Currently, quantification of respiratory measurements requires a radiologist, trained analyst, or technician to recognize, identify, and manually annotate anatomical landmarks such as the lung lobes or airway in the chest. A fully‐automated deep learning system may eliminate the need for manual analysis, thereby improving efficiency and expanding applicability to a large number of CTs.

TRM: HIF-1 alpha KO Mice (CRE)

Hypoxia-inducible factor 1-alpha is a transcriptional regulator of the adaptive response to hypoxia. When activated under hypoxic conditions, it can turn on over 40 genes involved in a variety of physiological activities. The dysregulation or alteration by mutation can lead to pathophysiology in areas of energy metabolism, cancer, cell survival and tumor invasion.

Engineered Biomaterial to Prevent Endothelial Inflammation

Researchers at the University of California, Davis have developed a biocompatible material to mimic the glycocalyx, the natural layer of molecules that coats the outside of endothelial cells. This technology can be used to treat inflammation in diseases characterized by dysfunction in leukocyte-endothelial cell interactions.

A Simple Integrated Device For Assessing Lung Health

Chronic lung diseases, like asthma, impose critical challenges on both the patients and the physicians due to the complexity of the diseases. Not only are these diseases tough to accurately assess, many of the diseases can be impacted by other physical and sociological factors. Perhaps a greater difficulty lies in measuring the effectiveness and compliance of the medications including inhaled medications. The invention discovered at the University of California, Irvine, is an “all-in-one,” portable device that offers complete assessment of lung health. It also incorporates a novel technology for monitoring the effectiveness and compliance of a medication, thereby, providing a personalized treatment and care plan for adults and children with asthma.

Endoscopic Optical Coherence Tomography As A Minimally Invasive Lung Cancer Screening Tool To Guide Diagnosis And Therapy

Novel Anti-Bacterial, Anti-Fungal Nanopillared Surface

Medical devices are susceptible to contamination by harmful microbes, such as bacteria and fungi, which form biofilms on device surfaces. These biofilms are often resistant to antibiotics and other current treatments, resulting in over 2 million people per year suffering from diseases related to these contaminating microbes. Death rates for many of these diseases are high, often exceeding 50%. Researchers at UCI have developed a novel anti-bacterial and anti-fungal biocomposite that incorporates a nanopillared surface structure that can be applied as a coating to medical devices.

The invention secures the flow of air through the patients’ nasal passage without the need for uncomfortable bulky masks or bedside devices, making it a convenient and sustainable treatment method.

Sieve Container For Contactless Media Exchange For Cell Growth

Media that contains nutrients and growth factors is necessary to grow all types of cells, a process that is widely used in many fields of research. Such media should be routinely changed either to different media or a fresh batch of the same media. This change currently involves either using a pipette to transfer cells from their current dish of media to a new dish, or aspirating the media out of the dish and replacing it with new media. Both methods have inherent risks to stressing and damaging the cells. Researchers at UCI have developed a unique dish for growing cells that allows for safer aspiration of the old media, which reduces stress and damage to the cells.
