The nematode Caenorhabditis elegans was introduced as a model organism in biological
research by Sydney Brenner in the 1970s. Since then, it has been increasingly used for …

Oxidative stress is a natural physiological process where the levels of oxidants, such as
reactive oxygen species (ROS) and nitrogen (RNS), exceed the strategy of antioxidant …

Natural products are small molecules naturally produced by multiple sources such as plants,
animals, fungi, bacteria and archaea. They exert both beneficial and detrimental effects by …

The health beneficial effects of a diet rich in fruits and vegetables are, at least in part,
attributed to polyphenols that are present in many herbal edibles. Although many in vitro …

Oxidative stress is a toxic state caused by an imbalance between the production and
elimination of reactive oxygen species (ROS). ROS cause oxidative damage to cellular …

The effect of aging on the ability of Caenorhabditis elegans to adapt to oxidative stress was
examined. Oxidative stress was applied with the quinone plumbagin or with hyperoxia, both …

The free radical theory of aging proposes a causal relationship between reactive oxygen
species (ROS) and aging. While it is clear that oxidative damage increases with age, its role …

Seaweeds are rich sources of bioactive compounds with potential health benefits. Anti-
stress effects of the cultivated red alga, Chondrus crispus, were investigated in the …

Quercetin is a major flavonoid in the human diet and the most commonly used in studies of
biological activity. Most of the knowledge about its biological effects has originated from in …

Quercetin is one the most abundant flavonoids in the human diet. Although it is well known
