Effects of grape extracts on the in vitro activity of enzymes involved in oxidative stress regulation
(2011)Background/Aim: A number of in vitro and in vivo studies have investigated the potential preventive activity of grape extracts against different diseases, and have mostly focused on their antioxidant properties. The present ... -
Enhancement of Antioxidant Mechanisms and Reduction of Oxidative Stress in Chickens after the Administration of Drinking Water Enriched with Polyphenolic Powder from Olive Mill Waste Waters
(2017)The aim of the study was to examine the effects of a polyphenolic powder from olive mill wastewater (OMWW) administered through drinking water, on chickens' redox status. Thus, 75 chickens were divided into three groups. ... -
Extracts from the mediterranean food plants Carthamus lanatus, Cichorium intybus, and Cichorium spinosum enhanced GSH levels and increased Nrf2 expression in human endothelial cells
(2018)The Mediterranean diet is considered to prevent several diseases. In the present study, the antioxidant properties of six extracts from Mediterranean plant foods were assessed. The extracts' chemical composition analysis ... -
Feed supplemented with polyphenolic byproduct from olive mill wastewater processing improves the redox status in blood and tissues of piglets
(2015)In the present study, a polyphenolic byproduct from olive mill wastewater (OMWW) was used for making piglet feed with antioxidant activity. For examining the antioxidant capacity of the feed, 30 piglets of 20 d old were ... -
Glycerol and glycerol-based deep eutectic mixtures as emerging green solvents for polyphenol extraction: The evidence so far
(2020)The acknowledgement that uncontrolled and excessive use of fossil resources has become a prime concern with regard to environmental deterioration, has shifted the orientation of economies towards the implementation of ... -
Grape stem extracts from three native Greek vine varieties exhibit strong antioxidant and antimutagenic properties
(2020)Background/Aim: The winemaking procedure results in the generation of stems, a by-product that is harmful to the environment. Concomitantly, stems are rich in polyphenols and, hence, they are putatively beneficial for human ... -
A green extraction process for polyphenols from elderberry (Sambucus nigra) flowers using deep eutectic solvent and ultrasound-assisted pretreatment
(2020)Sambucus nigra flowers, known as elderberry flowers (EBF), are a plant tissue rich in polyphenolic phytochemicals with important bioactivities. However, there are few studies dealing with the production of polyphenol-containing ... -
Inhibition of ozone-induced SP-A oxidation by plant polyphenols
(2007)Surfactant protein-A (SP-A) is the best studied and most abundant of the protein components of lung surfactant and plays an important role in host defense of the lung. It has been shown that ozone-induced oxidation of SP-A ... -
MacroDevelopment of an assay to assess genotoxicity by particulate matter extract
(2017)The current study describes a method for assessing the oxidative potential of common environmental stressors (ambient air particulate matter), using a plasmid relaxation assay where the extract caused single-strand breaks, ... -
Nanosystems for the encapsulation of natural products: The case of chitosan biopolymer as a matrix
(2020)Chitosan is a cationic natural polysaccharide, which has emerged as an increasingly interesting biomaterialover the past few years. It constitutes a novel perspective in drug delivery systems and nanocarriers’ formulations ... -
Novel feed including olive oil mill wastewater bioactive compounds enhanced the redox status of lambs
(2018)Background/Aim: The aim of the present study was to investigate the antioxidant effects of a feed supplemented with polyphenolic additives from olive mill wastewater (OMW) on lambs. Materials and Methods: Lambs received ... -
Olive oil with high polyphenolic content induces both beneficial and harmful alterations on rat redox status depending on the tissue
(2020)Olive oil (OO) possesses a predominant role in the diet of Mediterranean countries. According to a health claim approved by the European Food Safety Authority, OO protects against oxidative stress‑induced lipid peroxidation ... -
Optimization of the vacuum microwave assisted extraction of the natural polyphenols and flavonoids from the raw solid waste of the pomegranate juice producing industry at industrial scale
(2021)Pomegranate pomace (PP) is the solid waste produced in bulk by the pomegranate juice industry which is rich in polyphenols and flavonoids that can replace the hazardous chemical antioxidants/antimicrobials currently used ... -
