collection of multiple processes that increase the chronological age of an organism leading to death is defined as aging, and even though important, it is poorly understood. recent research has shown that aging is due to biochemical and genetic changes, in interaction with environmental effects, including diet and nutrition. most knowledge on aging is based on ge­netic model system, but its mol...

background & aim: medicinal plants can be a good replacement for common cancer treatment including chemotherapy, radiation therapy and surgery because they don’t have many side effects. the aim of this study was to investigate the effect of temperature on the free radical scavenging in the presence of medicinal plants. experimental: for determination of free radical scavenging activity was...

A new type of nanocomposite hydrogels based on covalent cross-linked interactions with excellent mechanical properties and good stability has been prepared by using in situ free-radical polymerization; polystyrene nanoparticles with photo-activity are used as the cross-linking agent.

Free radical polymerization of B-vinyl- and B-styryl-functionalized azaborinine monomers gives well-defined hybrid polymers that were fully characterized by multinuclear NMR and GPC analysis; their solubility, thermal characteristics, and photophysical properties are dramatically different from those of the all-carbon polystyrene analogues.
