You may not have heard of oxidative stress, but it’s a common process in the body with a wide range of potential effects. It refers to an imbalance of potentially toxic free radicals and the antioxidants that can neutralize them. While some level of oxidative stress is normal and even ...
As Ros attack a variety of organic substrates, oxidative stress can be evaluated by measuring reaction products of oxidative damage. Ozonetherapy acts as an added stress and it is imperative to carry out tests to assess any negative influence of ozone. Critical substrates are lipids, proteins, ...
A key element of acquisition of nutritional metals is the release of exudates with chelator properties from the roots into the rhizosphere. This complex formation enhances metal solubility and therefore provides a better uptake into the plant. A prominent example is the release of phenolic compounds ...
Oxidative stress is a product of an imbalance that occurs between antioxidants and free radicals in the body. Free radicals are molecules that contain oxygen but have an uneven amount of electrons. They cannot stay uneven much longer. And as a consequence, they end up pairing up with other ...
NOXO1 is a component of the NOX1 complex, which produces tissue-damaging molecules called reactive oxygen species (ROS). ROS, or more accurately, theoxidative stresscaused by these molecules, can result in mutations in the DNA of stomach cells, leading to tumor formation. Inflammation caused by...
In another set of experiments with flies, the researchers tested the oxidative stress link by expressing the brain's SOD1 gene, which is known to cleanse cells of reactive oxygen species caused by oxidative stress. When this gene was activated in the fruit fly brains, the flies' innate immune...
Furthermore, excessive alcohol intake is associated with a higher risk of developing cataracts, a condition where the lens of the eye becomes cloudy, obstructing vision. The antioxidants that protect the eyes from oxidative stress are diminished with chronic alcohol use, increasing the likelihood of ...
Stress has long been considered to be a major contributor to the clinical manifestation of many diseases. In this review the role that stress might play in is considered. Sufficient evidence is available to support the notion that stress could be a contributing factor in periodontal destruction in...
DNA polymerases were named for their function of catalysing DNA replication, a process that is necessary for growth and propagation of life. DNA involving Watson–Crick base-pairing can be synthesized with high fidelity, the structural and mechanistic origins of which have been investigated for many...
First, let’s talk aboutglycation.Glycation is caused by the presence of excess glucose, or sugar, in skin fibers. This excess triggers an internal reaction where sugar molecules adhere to collagen and elastin proteins. Usually, these proteins work together to help keep skin firm and supple. ...
