The role of the glutathione-dependent antioxidant system in the prooxidant-antioxidant balance support was studied in the experiments with Wistar male rat under single gamma-irradiation (8 Gr dose), fed with unbalanced (as to animal proteins and antioxidant vitamins) diet and with addition of Aronia
Herbicides containing paraquat may contribute to the pathogenesis of neurodegenerative disorders such as Parkinson's disease. Paraquat induces reactive oxygen species-mediated apoptosis in neurons, which is a primary mechanism behind its toxicity. We sought to test the effectiveness of a
BACKGROUND
Glutamate (an endogenous excitatory neurotransmitter) at high concentrations contributes to the development of neurodegenerative diseases. Aronia melanocarpa (A. melanocarpa) berries contain anthocyanins and have high antioxidant activities. In this study, we evaluated whether A.
Plant antioxidants protect cells against oxidative stress. Because oxidative stress (measured by different biomarkers) is observed in breast cancer patients, the aim of this study was to establish the effects of a polyphenol-rich extract of Aronia melanocarpa (final concentration of 50 microg/mL, 5
OBJECTIVE
Our investigations was to estimate the influence of Aronia anthocyanins (Aronox by Agropharm) on selected parameters of oxidative and antioxidative balance as well as on the concentration of selected metals in red blood cells in men with hipercholesterolaemia.
METHODS
16 men aged 27 +/-
Oxidative stress underlies the pathomechanisms of toxic action of cadmium (Cd), including its damaging impact on the oral cavity. This study investigated whether the administration of an extract from Aronia melanocarpa L. berries (AME), characterized by their strong antioxidative potential,
Aronia melanocarpa fruits (Rosaceae) and grape seeds (seeds of Vitis vinifera, Vitaceae) are two of the richest plant sources of phenolic substances, and they have been shown to have various biological activities. The aim of the present study was to investigate and compare the action of phenolic
The study investigated, in a rat model of low-level and moderate environmental exposure to cadmium (Cd; 1 or 5 mg Cd/kg diet, respectively, for 3 to 24 months), whether the co-administration of 0.1% extract from Aronia melanocarpa L. berries (AE) may protect against oxidative stress in the
Aronia melanocarpa fruits are rich in phenolic substances-mainly flavonoids from the anthocyanin subclass. The anthocyanins are water-soluble plant pigments with antioxidant, anti-inflammatory, antimicrobial, hepatoprotective, gastroprotective and other activities. We studied the effect of A.
Despite being a plant by-product, chokeberry pomace is believed to exert some therapeutic effects because it is one of the richest sources of highly bioavailable non-enzymatic antioxidants. The aim of this study was to determine the functionality of bioactive compounds present in the Aronia
The shift of prooxidant-antioxidant balance in side of prooxidants was revealed in rat liver mitochondria and in microsomes and in blood plasma in response to single irradiation (dose 8 Gy). The shift was more expressed in animals with nutrition unbalanced on animal proteins and antioxidant
We hypothesized that a polyphenol-rich chokeberry extract (CBE) would modulate hepatic lipid metabolism and improve antioxidant function in apolipoprotein E knockout (apoE(-/-)) mice. ApoE(-/-) mice were fed diets containing 15% fat with 0.2% cholesterol alone or supplemented with 0.005% or 0.05%
BACKGROUND
Anthocyanins are one of the most important water-soluble plant pigments. They belong to flavonoids and are derivatives of 2-phenylo-benzo-gamma pyren. They have antioxidant and anti-inflammatory properties and, therefore, may be potentially used to combat oxidative stress, frequently
Since the extract from berries of Aronia melanocarpa presents antioxidative properties in plasma and in blood platelets, not only from healthy group, but also from patients with benign breast diseases and in patients with invasive breast cancer before surgery, the aim of our present study was to
Cadmium (Cd) is a strongly toxic heavy metal with prooxidative properties. Since the exposure of the general population to this metal is predicted to increase, effective methods are being sought to prevent its negative actions. One of them involves the use of the antioxidant potential of polyphenol
