friedreichs ataxia (frda) is an inherited recessive disorder characterized by progressive neurological disability and heart abnormalities. a deficiency in the protein frataxin causes this disease. frataxin deficiency leads to progressive iron accumulation in mitochondria, excessive free radical production and dysfunction of respiratory chain complexes. the expansion (gaa) repeat in the first in...

Background: Varicocele is the abnormal tortuosity and dilatation of the veins of the pampiniform plexus within the spermatic cord. Varicocele-related pathology is suspected in infertility as it leads to elevated temperatures in the scrotum and testes, which has a deleterious effect on spermatogenesis. In Varicocele patients, ROS production is enhanced and total antioxidant capacity (TAC) is red...

When pooled immunoglobulin G (IgG) from patients with multiple sclerosis (MS) was used to probe a human fetal spinal cord λgt 11 cDNA library, the IgG was found to bind to a predicted epitope of human mitochondrial ND4 sequence. To investigate the involvement of the ND4 as an autoantigen in MS, we determined the presence of specific antibody in the serum of MS patients and serum samples of...
