The cardioprotective effects of red wine have been attributed to several polyphenolic antioxidants including resveratrol and proanthocyanidins. The goal of the present study was to determine whether white wines could also provide cardioprotection. Three different white wines (white wine #1, #2 and
To study if white wines, like red wine, can also protect the heart from ischemia reperfusion injury, ethanol-free extracts of three different white wines (WW1, WW2 and WW3) (100 mg/100 g body weight) were given orally to Sprague Dawley rats (200 g body weight) for three weeks. Control rats were
Wine phenolics have been reported to have health benefits, including protection against cardiovascular diseases and anticarcinogenic effects. White wines are usually made with the free-running juices without pomace, which has no contact with the grape skins. This is the main reason that the phenolic
Lower antioxidant activity in white wines in comparison to red wines lies in the low grape-skin-derived polyphenol content. This paper reports the analysis of the antioxidant capacities of white wine samples obtained along two different processing procedures directed to enrich the wine with
The biochemistry of reactive oxygen species is an important field with wide implications. Both preventive and chain breaking antioxidants have a role in the limitation of oxidative stress that accompanies aging and diseases. The potent antioxidant activity of phenolic substances of red wine, in
The reactivity of SO2 with the 2,2-diphenyl-1-picrylhydrazyl radical (DPPH) and in Folin Ciocalteu (FC) assays was analysed under different experimental conditions. There was significantly higher reactivity between SO2 and DPPH in buffered methanol than in methanol alone. When DPPH and FC assays
The aim of the research was to study the influence of long-term stress conditions on the rate of lipids' peroxidation (LPO), activity of antioxidant system and energy metabolism in brain, cardiac muscle and lymphocytes under 30-days isolation and diurnal cycle violation. Obtained results prove about
Selective lignin degrading white rot fungi viz. Phanerochaete chrysosporium, Phlebia brevispora, and Phlebia floridensis were selected to evaluate antioxidant potential and auxin (indole acetic acid) production in complex and synthetic medium. Antioxidant potential of these fungi was tested against
We present a 76-year old woman with a five-year history of asymptomatic, white papules that were grouped on the lateral and posterior aspects of the neck, inferior axillae, and central mid-back. The histopathologic findings showed thickened collagen bundles. A diagnosis of white fibrous papulosis of
Different winemaking products (ascorbic acid, glutathione, yeast lees and a yeast autolysate) were tested in comparison with sulphur dioxide, concerning radical scavenging activity (measured by DPPH assay), oxygen consumption capacity and ability to reduce wine colour and predisposition to browning.
A review of the literature on the 'antioxidant' action of white wines on the cardiovascular system is given. The conclusion is that ingestion only of white wines very low, or lacking, in polyphenolics leads to a reduction in the antioxidant action of blood serum, and to an increase in the low
This review aims to clarify novel concepts regarding the clinical and laboratory aspects of white-coat hypertension (WCHT). Recent studies on the clinical and biological implications of WCHT were compared with existing knowledge. Studies were included if the WCHT patients were defined according to
The purpose of this study was to improve the physical color stability of official white lotion to a point where a freshly prepared lotion would not be necessary. Three anioxidants (ascorbic acid, sodium metabisulfite and sodium sulfite) were added into official white lotion in a concentration of
Grape seeds represent a high percentage (20% to 26%) of the grape marc obtained as a byproduct from white winemaking and keep a vast proportion of grape polyphenols. In this study, seeds obtained from 11 monovarietal white grape marcs cultivated in Northwestern Spain have been analyzed in order to
