Guanidinoacetate alters antioxidant defenses and butyrylcholinesterase activity in the blood of rats
Background and Aim: Despite many researches done on the relationship between oxidative stress and cellular antioxidant defenses in different cancers, there are limited researches about the role of oxidative stress in bladder cancer. So we decided to study the serum MDA and total antioxidant capacity in patients with bladder cancer in comparison with healthy individuals. Materials and Method...
Abstract Glaucoma is a neurodegenerative disease that affects eye structures and brain areas related to the visual system. Oxidative stress plays key role in development progression of disease. The aims present study were evaluate mitochondrial function its participation redox metabolism an experimental glaucoma model. 3-month-old female Wistar rats subjected cauterization two episcleral veins ...
Reactive oxygen and nitrogen species produced by metabolism and immune defenses can cause extensive damage to biomolecules. To counteract this damage, organisms rely on exogenous and endogenous antioxidants, although their relative importance in maintaining redox balance is unclear. We supplemented captive greenfinches with dietary antioxidants--carotenoids and vitamin E--and injected them with...
Figure 1. Structures of the various tocopherol and tocotrienol vitamers. Introduction There are eight vitamers of vitamin E (alpha-, beta-, gamma-, and delta-tocopherols and the corresponding tocotrienols) (Figure 1), differing in their biological activity and distribution in foods. Most often vitamin E’s role is usually associated with its antioxidant activity. For example, α-tocopherol is a w...
