USE OF THE ORAC-PYROGALLOL RED/ORAC-FLUORESCEIN RATIO TO ASSESS THE QUALITY OF ANTIOXIDANTS IN CHILEAN WINES [PDF]

Journal of the Chilean Chemical Society, 2011
ABSTRACT We have recently proposed that ORAC (Oxygen Radical Absorbance Capacity) methods employing fluorescein (ORAC-FL) and pyrogallol red (ORAC-PGR) as target molecules could be considered as complementary indexes. In particular, the ratio ORAC-PGR/ORAC-FL would reflect the average quality of the antioxidants present in a particular sample.

Oracally Efficient Two-Step Estimation of Generalized Additive Model [PDF]

Journal of the American Statistical Association, 2011
The generalized additive model (GAM) is a multivariate nonparametric regression tool for non-Gaussian responses including binary and count data. We propose a spline-backfitted kernel (SBK) estimator for the component functions and the constant, which are oracally efficient under weak dependence.

Awareness of ORAC assay among dental students

International Journal of Research in Pharmaceutical Sciences, 2020
The Oxygen Radical Absorption Capacity (ORAC) assay estimates the suppression of radical-mediated oxidation by molecules of concern. This calculates the quality as equivalent and provides both repression duration and the degree of oxidation suppression. This same test could be used to calculate the antioxidant capacity of nutrition.

Oxygen radical absorbance capacity (ORAC) of cyclodextrin-solubilized flavonoids, resveratrol and astaxanthin as measured with the ORAC-EPR method

Journal of Clinical Biochemistry and Nutrition, 2012
Recently, we proposed an oxygen radical absorbance capacity method that directly quantifies the antioxidant's scavenging capacity against free radicals and evaluated the radical scavenging abilities for water soluble antioxidant compounds. In this study, we determined the radical scavenging abilities of lipophilic antioxidants which were solubilized by

Exploring the Anti‐Diabetic Potential of Anthocyanins: From Biochemical Pathways to Human Trials

Chronic Diseases and Translational Medicine, EarlyView.
ABSTRACT Diabetes mellitus (DM) is a global health challenge with increasing prevalence rates, particularly in low‐ and middle‐income countries. Anthocyanins (ACs) are potential bioactive compounds found in various fruits and vegetables, attracting the attention of researchers due to their possible role in managing diabetes and its complications ...

Novel Bioactive Multifunctional Polyphenols: A Chemo‐Enzymatic Approach

Chemistry – A European Journal, EarlyView.
One‐step synthesis of complex alkyl oxystilbenin glucosides (6‐47% yield) in alcoholic medium. Switching to ter‐BuOH as solvent afforded δ‐Viniferin diglucoside, with high selectivity and high yield (> 90%), that can be upgraded by enzymatic esterification to alkyl δ‐Viniferin diglucosides.

Tars: Timeliness-aware Adaptive Replica Selection for Key-Value Stores

, 2017
In current large-scale distributed key-value stores, a single end-user request may lead to key-value access across tens or hundreds of servers. The tail latency of these key-value accesses is crucial to the user experience and greatly impacts the revenue.

NATIONAL STATUSES GRANTED FOR PROTECTION REASONS IN IRELAND. ESRI RESEARCH SERIES NUMBER 96 January 2020 [PDF]

, 2020
This study examines the national statuses that may be granted for protection reasons in Ireland. The report focuses on national statuses with a sole basis in Irish domestic law and policy and does not examine in detail EU-harmonised statuses.
