Ontogeny of Antioxidant Systems

2014
Changes in the redox conditions of the biosphere have shaped the evolution of biological adaptations that permit successful energy capture and transfer by life forms. These include the systems that can scavenge molecular oxygen and nitrogen oxides.

Antioxidant System in Hepatocellular Carcinoma

1996
Oxygen radicals play an important role in the course of experimental and human carcinogenesis. Antioxidant enzymes have been shown to protect cells against oxidative damage and, thus, to inhibit both initiation and promotion of carcinogenesis. The antioxidant enzyme superoxide dismutase catalyses the dismutation of superoxide anion, a very toxic ...

Antioxidant systems in rat epididymal spermatozoa.

Biology of reproduction, 1998
Mammalian caput and cauda epididymidal spermatozoa exhibit diverse stages of maturation, and their plasma membrane shows diverse composition and stability levels, thus enabling these spermatozoa to undergo the acrosomal reaction after transit through the epididymis.

The skin's antioxidant systems.

Dermatology nursing, 2000
The skin is supplied with an antioxidant system that includes enzymatic and nonenzymatic components. This complex system is the skin's first-line defense against free-radical attacks. Antioxidants are essential in protecting the epidermis from damage by free radicals generated both by environmental and endogenous factors.

Alcohol and antioxidant systems.

Alcohol and alcoholism (Oxford, Oxfordshire), 1995
Following the pioneer report of Di Luzio (Physiologist 6, 169-173, 1963) concerning the prevention of the acute ethanol-induced fatty liver by antioxidants, many observations have shown that ethanol-induced liver injury may be linked, at least partly, to an oxidative stress resulting from increased free radical production and/or decreased antioxidant ...

Systemic antioxidants and skin health.

Journal of drugs in dermatology : JDD, 2013
Most dermatologists agree that antioxidants help fight free radical damage and can help maintain healthy skin. They do so by affecting intracellular signaling pathways involved in skin damage and protecting against photodamage, as well as preventing wrinkles and inflammation. In today's modern world of the rising nutraceutical industry, many people, in
