Interaction of polyphenols with model membranes: Putative implications to mouthfeel perception

In this study we investigated the interaction of astringent polyphenols, namely ECG, EGCG, procyanidin B4 and PGG, with lipids in model membranes by spectroscopic techniques. The membrane model was built varying the cholesterol content to mimic mouth regions and experiments were conducted at pH 5 to mimic the pH drop at the moment of beverage (e.g. green tea, red wine) intake.Fluorescence quenching results conducted on LUVs with cholesterol molar fractions ranging between 0.34

In conclusion, implementation of the CMD prevention program resulted in the detection of two- to threefold more patients with CMD. A significant drop in systolic blood pressure and cholesterol levels was found after one year of treatment. Modelling of these results should confirm the effect on long term endpoints.Trial registration: Dutch trial Register number NTR4277.

In this study, we found that nuclear receptors FXR and LXR (originally characterized as regulatory factors involved in cholesterol/bile acid homeostasis) regulate the expression of Oct3/4, a marker for cell differentiation, in both normal renal-derived cell line HK-2 and renal adenocarcinoma cell line ACHN. Down-regulation of Oct3/4 expression by activating FXR and LXR occurs only in normal renal cell-derived HK-2 cells. We also found that the RNA-binding protein, ELAVL2, oppositely regulates Oct3/4 expressions in HK-2 and ACHN cells. Moreover, we revealed that LXR-alpha and LXR-beta regulate each other's expression. Altho...

Over 30 million people in the United States live with diabetes, and approximately 7.7 million people have diabetic retinopathy, making it the most common cause of vision loss in working-aged adults. The prevalence of diabetic retinopathy has increased significantly over the past 20 years, due to the rise in the number of people diagnosed with diabetes. How does diabetes affect the retina? The retina is the light-sensing component located in the back of the eye. It is composed of blood vessels, nerve cells (neurons), and specialized cells called photoreceptors that are involved in directly sensing light. The ability of the ...

In this study, we reviewed in-vitro and in-vivo studies, as well as clinical reports pertaining to the antifungal efficacy of statins. In addition, we have addressed various modulators of statin anti-fungal activity and the potential mechanisms responsible for their anti-fungal effects. In general, statins do possess anti-fungal activity, targeting a broad spectrum of fungal organisms including human opportunistic pathogens such as Candida spp. and Zygomycetes, Dermatophytes, alimentary toxigenic species such as Aspergillus spp., and fungi found in device implants such as Saccharomyces cerevisiae. Statins have been shown t...

But, whether PGN affects the occurrence of steatohepatitis remains unclear. Here, we reported that subcutaneous infusion of purified PGN for 4 weeks significantly increased hepatic levels of triglyceride, inflammation and fibrosis in mice fed normal chow. These altera...

Extraction yield, fatty acid profile, nutritional impact and cholesterol content were determined and compared with the initial insects. The highest extraction yield corresponded to PLE-T. molitor extracts. A decrease in total saturated fat...
