Relationship of antioxidant enzyme activities with myelomeningocele [PDF]

Turkish Neurosurgery, 2011
To investigate the role of erythrocyte free radical scavenging enzyme activities (FRSE), carbonic anhydrase (CA) activity and malondialdehyde (MDA) in infants with myelomeningocele (MM).We compared antioxidant enzyme activities and MDA level in 40 individuals (10 infants with MM, 10 healthy infants; and mothers of these two groups) with age-matched ...

Saxitoxin Group Toxins Accumulation Induces Antioxidant Responses in Tissues of Mytilus chilensis, Ameghinomya antiqua, and Concholepas concholepas during a Bloom of Alexandrium pacificum

Antioxidants, 2022
Saxitoxin (STX) group toxins consist of a set of analogues which are produced by harmful algal blooms (HABs). During a HAB, filter-feeding marine organisms accumulate the dinoflagellates and concentrate the toxins in the tissues.

Indirect evaluation of corneal apoptosis in contact lens wearers by estimation of nitric oxide and antioxidant enzymes in tears

Oman Journal of Ophthalmology, 2010
Background : Contact lens induced trauma to the corneal epithelium results in increased release of inflammatory mediators. The keratocyte apoptosis is directly related to epithelial injury and has been correlated with increased production of nitric oxide.
