Methods of Discovering New Bile Acids and Use in Treating Inflammatory Diseases

A mosaic of cross-phyla chemical interactions occurs between all metazoans and their microbiomes. In humans, the gut harbors the heaviest microbial load, but many organs, particularly those with a mucosal surface, associate with highly adapted and evolved microbial consortia. The microbial residents within these organ systems are increasingly well characterized, yielding a good understanding of human microbiome composition. However, we have yet to elucidate the full chemical impact the microbiome exerts on an animal and the breadth of the chemical diversity it contributes. A number of molecular families are known to be shaped by the microbiome including short-chain fatty acids, indoles, aromatic amino acid metabolites, complex polysaccharides, and host sphingolipids and bile acids. These metabolites profoundly affect host physiology and are being explored for their roles in both health and disease. The synthesis of bile acids takes place in the liver and recent research has shown that bile acids can act as signaling molecules and activate a number of molecules. A primary focus has been on the Farnesoid X receptor (FXR) which plays an important role in bile acid synthesis and in regulation of glucose, lipid and energy metabolism.

Quantitative Determination Of Esterified Eicosanoids and Related Oxygenated Metabolites After Alkaline Hydrolysis

Eicosanoids and related metabolites, sometimes referred to as oxylipins, are a group of structurally diverse metabolites that derive from the oxidation of PUFAs, including arachidonic acid, linoleic acid, and linolenic acid, dihomo linolenic acid, eicosapentaenoic acid, and docosahexaenoic acid. They are locally acting bioactive signaling lipids that regulate a diverse set of homeostatic and inflammatory processes. Given the important regulatory functions in numerous physiological and pathophysiological states, the accurate measurement of eicosanoids and other oxylipins is of great clinical interest and lipidomics is now widely used to screen effectively for potential disease biomarkers.

Circulating Lipidomic Signature To Identify Nonalcoholic Fatty Liver Disease

Fatty liver disease (or steatohepatis) is often associated with excessive alcohol intake or obesity, but also has other causes such as metabolic deficiencies including insulin resistance and diabetes. The causation of a fatty liver results from triglyceride fat accumulation in vacuoles of the liver cells resulting in decreased liver function, and possibly leading to cirrhosis or hepatic cancer. Non-alcoholic fatty liver disease (NAFLD) represents a spectrum of disease occurring in the absence of alcohol abuse. There is a clinical need for a simple test to identify individuals with nonalcoholic fatty liver disease (NAFLD) in the population. While circulating lipids have been used for this purpose, the large number of analytes within the human lipidome makes it cumbersome to utilize this approach for high throughput screening.

Mitochondrial Respirometry In Frozen Specimens

UCLA researchers from the Department of Medicine have developed a novel technique for performing mitochondrial respirometry in frozen specimens to accurately assess the cellular energy production capacity.

A Method and Device for the Estimation of Blood Glucose Concentration from Signals of Sensors Implanted in Tissues

Diabetes is a major disease affecting all populations and age groups, and society as a whole. All therapies for diabetes are based on achieving close glucose control. Close glucose control achieved by sufficient and timely administration of therapy has been shown to reduce the destructive “long-term complications” of diabetes, such as retinal damage, kidney failure, amputations, and cardiovascular damage, as well as debilitating and life-threatening short-term hypoglycemia. However, attainment of close control requires a means of glucose monitoring and means for correction of glucose imbalances such as administration of insulin, pharmaceuticals, diet adjustment, and exercise, based on the monitored glucose concentration.

Combination Immunotherapies for Treatment of Liver Cancer

Primary liver cancer, with the majority being hepatocellular carcinoma (HCC), is now the second leading cause of cancer mortality and the fifth most common cancer worldwide, claiming approximately 800,000 life every year. HCC is a chemotherapy resistant tumor with limited treatment options including surgical resection, liver transplantation and local ablation at the early stages. Sorafenib, a multi-kinase inhibitor, remains a first-line systemic drug for advanced HCC even with poor outcomes, and similar low therapeutic benefits were reported for regorafenib, lenvatinib, and cabozantinib. Over 100 clinical trials that tested other compounds or approaches have failed to show therapeutic benefit to HCC patients. Immunotherapy by blocking inhibitory pathways in T lymphocytes, such as the PD-L1/PD-1 axis, is being widely tested in various solid tumors. Notably, this emerging therapeutic approach is already in clinical trials for advanced HCC in multi-centers around the globe. Two latest reports on open-label, non-randomized, phase 1/2 trials with pembrolizumab or nivolumab indicated manageable safety in advanced HCC patients with or without prior sorafenib treatment, albeit with very limited therapeutic benefits observed so far. The outcome of immunotherapy for liver cancer can be compounded by the unique immunotolerant microenvironment in the liver. A variety of clinical trials are ongoing to evaluate combination of immune checkpoint inhibitors or with other drugs, without clear justification or support by preclinical data.

High Frequency Digital Frequency Domain Fluorescence Lifetime Imaging System For Applications On Tissues

The technology is a software/hardware combination designed to enhance sampling rate for frequency domain fluorescence lifetime imaging. Fluorescence lifetime imaging microscopy (FLIM) is a technique that uses signals emitted from fluorescent samples to construct images of those samples in near real time. An advantage to FLIM is its ability to image large fields of view, which makes it an attractive option for dynamical measurements of live biological tissues. The higher sampling rate available using this technology will allow for more information to be gleaned from biological samples, which may have a fluorescence band up to 1 GHz, advancing tissue imaging.

TREATING TYPE-1 DIABETES BY PRESERVING BETA CELL FUNCTION

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.

A Method for Inhibition of de novo Lipogenesis

The obesity epidemic currently afflicting the US and other developed countries has resulted in a marked increase in the incidence of the metabolic syndrome and its associated pathologies, including nonalcoholic fatty liver disease (NAFLD), estimated to affect 30% of Americans. Although NAFLD is characterized by lipid droplet buildup in hepatocytes, it is not accompanied by liver damage, inflammation, and fibrosis unless combined with other risk factors, such as endoplasmic reticulum (ER) stress or mitochondrial dysfunction. In the context of simple, nonsymptomatic liver steatosis, ER stress or mitochondrial dysfunction trigger nonalcoholic steatohepatits (NASH), a serious disease that can progress to liver cirrhosis, resulting in loss of liver function, and hepatocellular carcinoma (HCC), one of the most deadly cancers.

Diagnosis and Treatment of Inflammatory Disease by Glycan Profiling of High Density Lipoprotein (HDL)

Researchers at the University of California, Davis have developed a method for diagnosing an individual patient’s risk of inflammatory disease based on glycan profiling of high density lipoprotein (HDL). The resulting profile is then used to recommend a treatment program of dietary, lifestyle, or pharmaceutical interventions (or combination thereof), to improve health and decrease the risk of inflammation-induced disease by modulating the patient’s HDL glycosylation pattern.

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.
