This paper reviews the potential role of honey as a therapeutic antioxidant to reduce oxidative stress and improve cognitive ageing. All articles indexed to PubMed Central (PMC) were searched using the following key words: honey, antioxidant, memory and ageing. Honey is a natural insect-derived product with therapeutic, medicinal and nutritional values. Antioxidant properties of honey quench bi...
the application of e-learning systems - as one of the solutions to the issue of anywhere and anytime learning – is increasingly spreading in the area of education. content management - one of the most important parts of any e-learning system- is in the concern of tutors and teachers through which they can obtain means and paths to achieve the goals of the course and learning objectives. e-learn...
Introduction: Zinc is part of the antioxidant system, so zinc deficiency impairs the body's antioxidant defense system and leads to increased oxidative stress. The objective of this study was to investigate the effect of zinc oxide on the antioxidant status in rat. Methods: Twenty-five male Wistar rats of 5-8 weeks’ old were divided into five groups of five animals each. Next, du...
Cadmium (Cd) disrupts the normal growth and development of plants, depending on their tolerance to this toxic element. The present study was focused on the impacts of exogenous salicylic acid (SA) on the response and regulation of the antioxidant defense system and membrane lipids to 16-day-old flax plantlets under Cd stress. Exposure of flax to high Cd concentrations led to strong inhibition o...
Preterm infants are vulnerable to the oxidative stress due to the production of large amounts of free radicals, antioxidant system insufficiency, and immature oligodendroglial cells. Reactive oxygen species (ROS) play a pivotal role in the development of periventricular leukomalacia. The three most common ROS are superoxide (O2(•-)), hydroxyl radical (OH(•)), and hydrogen peroxide (H2O2). Under...
The increase in oxygen uptake during intense exercise is associated with an increase in the production of reactive oxygen species, a process known as oxidative stress, which may alter cell contents. To limit the damaging effect of this overload of free radicals, the antioxidant defense system must be effective. The repetition of endurance training stimuli causes adaptations of the antioxidant d...
