This study was conducted to evaluate the effect of beta-mercaptoethanol (a stimulator of glutathione synthesis) and Trolox (an hydrosoluble analogue of Vitamin E) on bovine embryos cultured from the morula stage (Day 5 post-insemination; pi) under oxidative stress conditions. Culture of embryos with
Ischemia, and subsequent acidosis, induces neuronal death following brain injury. Oxidative stress is believed to be a key component of this neuronal degeneration. Acute chemical ischemia (azide in the absence of external glucose) and acidosis (external media buffered to pH 6.0) produce increases in
Several studies reveal that vitamin E acts as a cellular stabilizer of unsaturated lipids against oxidative deterioration, thus maintaining structural and functional integrity at the subcellular level. The objective of this study was to evaluate Vitamin E (Trolox) addition to freezing extender for
Two-dimensional proteomic maps of soleus (Sol), a slow oxidative muscle, and gastrocnemius (Gas), a fast glycolytic muscle of control mice (CTRL), of mice hindlimb unloaded for 14 days (HU mice) and of HU mice treated with trolox (HU-TRO), a selective and potent antioxidant, were compared. The
OBJECTIVE
Photodynamic treatment (PDT) of red blood cell (RBC) suspensions has been reported to result in virus inactivation, but also in deterioration of cell quality. Recently, we have demonstrated the potential usefulness of the reactive oxygen species scavenger dipyridamole in selectively
Oxidative stress promotes controlled mechanical ventilation (MV)-induced diaphragmatic atrophy. Nonetheless, the signalling pathways responsible for oxidative stress-induced muscle atrophy remain unknown. We tested the hypothesis that oxidative stress down-regulates insulin-like growth
Introduction: Reperfusion surgery following testicular ischemia is a reproductive health threatening status and may result with organ dysfunction in men. The high level of reactive oxygen species (ROS) and cease of blood flow to the
Prolonged hyperglycemia results in a number of diabetic complications, including retinopathy. Pericyte degeneration is one of the earliest histological changes observed in the development of diabetic retinopathy. Increased free radicals generated under hyperglycemia could damage the retina, which
Retinoids are present in human tissues exposed to light and under increased risk of oxidative stress, such as the retina and skin. Retinoid cation radicals can be formed as a result of the interaction between retinoids and other radicals or photoexcitation with light. It has been shown that such
The aim of this investigation was to determine whether an ingredient of green tea, epigallocatechin gallate (EGCG) could attenuate oxidative stress-induced degeneration of the retina as occurs in age-related macular degeneration (AMD) and glaucoma. Initial in vitro studies on brain membranes showed
Prolonged mechanical ventilation results in diaphragmatic oxidative injury, elevated proteolysis, fiber atrophy, and reduced force-generating capacity. We tested the hypothesis that antioxidant infusion during mechanical ventilation would function as an antioxidant to maintain redox balance within
OBJECTIVE
It has been shown that the functionality of the macula lutea depends on the nutritional uptake of lutein and zeaxanthin and that it is inversely associated with the risk of age-related macular degeneration (AMD). Additionally, ω-3 long-chain polyunsaturated fatty acids (LC-PUFAs) may also
1. Although alpha-tocopherol has been shown to improve renal function following ischaemia-reperfusion (I/R) injury, its clinical use is not common because alpha-tocopherol requires several days of pretreatment to exhibit anti-oxidative benefits. The advent of trolox, a water-soluble analogue of
OBJECTIVE
The aim of this study was to analyze biomarkers of oxidative stress in patients with wet age related macular degeneration (AMD).
METHODS
Case-control study that includes 163 patients with wet AMD (age group of 55-82 years with the mean age of 71 years and 170 age-matched healthy controls
Oxidative stress was proposed as a trigger of muscle impairment in various muscle diseases. The hindlimb-unloaded (HU) rodent is a model of disuse inducing atrophy and slow-to-fast transition of postural muscles. Here, mice unloaded for 14 days were chronically treated with the selective antioxidant
