The Antioxidant Phytochemicals of Nutraceutical Importance

Over production of free radicals result in oxidative stress that deregulates the cellular and metabolic functions. Phytochemicals with antioxidant property are of great interest due to their beneficial effects on human health as they offer protection against metabolic dysfunction, gastro-duodenal pathogenesis, premature aging, inflammation, rheumatoid arthritis, atherosclerosis, cancer, neuro-d...

Antioxidant phytochemicals against type 2 diabetes.

Dietary phytochemicals, of which polyphenols form a considerable part, may affect the risk of obesity-associated chronic diseases such as type 2 diabetes. This article presents an overview on how phytochemicals, especially polyphenols in fruits, vegetables, berries, beverages and herbal medicines, may modify imbalanced lipid and glucose homeostasis thereby reducing the risk of the metabolic syn...

Antioxidant Phytochemicals for the Prevention and Treatment of Chronic Diseases.

Overproduction of oxidants (reactive oxygen species and reactive nitrogen species) in the human body is responsible for the pathogenesis of some diseases. The scavenging of these oxidants is thought to be an effective measure to depress the level of oxidative stress of organisms. It has been reported that intake of vegetables and fruits is inversely associated with the risk of many chronic dise...

Refraction at the Interface of a Lossy Metamaterial

The refraction phenomenon at the interface of an ordinary material and a lossy metamaterial has been investigated. For oblique incidence on the lossy metamaterial, the planes of constant amplitude of the refracted wave are parallel to the interface and the plane of constant phases make a real angle with the interface (real refraction angle). The real refraction angle and hence, the real refract...
