This study examines the glutathione status of red blood cells in patients with retinopathy of prematurity (ROP) both in vivo and after an in vitro oxidative challenge. Fifty ROP patients of different ages (between 6 weeks and 6 years), born prematurely (gestational age: 28.7 +/- 1.3 weeks; birth
OBJECTIVE
Glutathione peroxidase-1 (GPx1) is highly expressed during normal retinal maturation; however, its role in retinopathy of prematurity (ROP) is not fully understood. We postulated that GPx1 plays an important role in protecting the premature retina from oxidative injury in a mouse model of
Oxygen radical injury may be one of the factors leading to Retinopathy of Prematurity. It occurs when the body's natural antioxidant capacity is overwhelmed by the free oxygen radicals produced during the perinatal period. Supposing, that premature infants may have defects in their antioxidant
BACKGROUND
Retinopathy of prematurity (ROP) is the main cause of visual impairment in premature infants and is considered to be a multifactorial disease. Because of the similarity between the human retina and the erythrocyte concerning their antioxidant mechanism, the aim of this study was to
One of the most frequently observed causes of blindness in infancy is the pathogenesis known as retinopathy of prematurity (ROP). Angiotensin-converting enzyme (ACE) is a vital enzyme in the renin-angiotensin-aldosterone system; it is involved in the development of cardiovascular system diseases
By world standards, the selenium status of the adult population of Christchurch, New Zealand is low. To determine the status of infants undergoing neonatal intensive care, plasma and red cell selenium and glutathione peroxidase levels were measured in infants admitted to the regional neonatal unit.
OBJECTIVE
Retinopathy of prematurity (ROP) is one of the most frequent causes of blindness in newborn babies. Currently, its etiology is not fully understood.-In this study we aimed to investigate the correlation between a patient group with ROP and a control group in terms of the tumor necrosis
The study was carried out on 60 oxygen-treated premature infants weighed less than 2000 g (1529 +/- 302 g, x mean +/- S. D.) and on their mothers. Both the Retinopathy of Prematurity screening and the biochemical tests were started at the age of 6 weeks. According to our results, the signs of an
Purpose: To investigate the influence of polymorphisms in vascular endothelial growth factor (VEGF), tumor necrosis factor-α (TNF-α), and glutathione S-transferase Pi isoform (GSTP1) genes on retinopathy of prematurity (ROP) risk, we performed a Preferred Reporting Items
Retinopathy of prematurity (ROP) is a major cause of blindness in children. Free radicals are implicated in the development of this retinopathy. We studied the role of free radicals in ROP and enrolled 60 preterm neonates at 30-32 weeks age. Thirty neonates predisposed to development of ROP, were
The number and total volume of blood transfusions received by premature babies is, after gestational age and birth weight a good predictor of the likelihood of developing chronic lung disease of prematurity (CLD) and retinopathy of prematurity (ROP). Oxidative damage, inflammation and pulmonary
The antioxidant glutathione is found in low levels in diseases in which increasing evidence implicate oxidative stress in the development of the disease, for example retinopathy of prematurity, necrotizing enterocolitis, bronchopulmonary dysplasia, patent ductus arteriosus and asthma. Glutathione is
BACKGROUND
Resuscitation at birth with 100% oxygen is known to increase the oxidative burden with concomitant deleterious effects. Although fractions of inspired oxygen (FiO₂) < 100% are widely used in preterm infants, starting resuscitation at a (too) low FiO₂ may result in hypoxia. The objective
The purpose of this study was to determine whether melatonin treatment would mitigate retinal ganglion cell (RGC) death in the developing retina following a hypoxic insult. Lipid peroxidation (LPO), glutathione (GSH), tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) concentrations,
Deficient antioxidant defenses in preterm infants have been implicated in diseases such as bronchopulmonary dysplasia, retinopathy of prematurity, necrotizing enterocolitis, periventricular leukomalacia, and intraventricular hemorrhage. The antioxidant properties of selenium make it important in the
