Oxidative Stress News and Research

RSS

Oxidative Stress is a condition in which antioxidant levels are lower than normal. Antioxidant levels are usually measured in blood plasma.

Scientists study adverse effects of carbon, silicon nanotubes and carbon nanofibers

Nanoparticles with a wide range of applying, including medicine, damage cells of microalgae Heterosigma akashivo badly. This algae species is widely spread in the Russian Far East marine area. The acute toxic effect exhibited at concentrations of 100 mg/l of carbon nanotubes and silicon nanotubes in the sea- or fresh water.

Scientists discover new target to treat blood vessel damage in diabetes

In diabetes, both the tightly woven endothelial cells that line our blood vessels and the powerhouses that drive those cells start to come apart as early steps in the destruction of our vasculature.

Study: Oxidative stress can be used against tumors to treat cancer

Oxidative stress can help tumors thrive, but one way novel cancer treatments work is by pushing levels to the point where it instead helps them die, scientists report.

Research drug may one day be novel treatment for systemic inflammatory response syndrome

When trauma spills the contents of our cell powerhouses, it can evoke a potentially deadly immune response much like a severe bacterial infection.

Classifying heart failure patients based on redox status may help personalize treatment

For more than six decades, oxidative stress has been linked to heart failure, a progressive weakening of the heart muscle that can lead to death. While antioxidant supplements such as vitamin C, vitamin B and beta-carotene have been widely used in heart failure, they often prove ineffective.

Combination of probiotics and herbal supplement may prolong lifespan, research shows

You are what you eat. Or so the saying goes. Science now tells us that we are what the bacteria living in our intestinal tract eat and this could have an influence on how well we age.

Scientists find enzyme that breaks down plasmalogens in Alzheimer's disease patients

Alzheimer's disease patients lose up to 60% of a component called plasmalogen from the membranes of the cells in their brains, but it's still not known how or why.

Cancer cells co-opt pain-sensing 'neural channel' to increase tolerance against oxidative stress

Anyone who's taken a bite of a sandwich with too much spicy mustard or a piece of sushi with too much wasabi can attest to the tear-inducing sensation these condiments can cause. These loud warnings to the nervous system of exposure to potentially harmful chemicals are triggered by TRPA1, a calcium channel protein sometimes referred to as the "wasabi receptor."

Mediterranean diet may protect people from negative effects of air pollution

Eating a Mediterranean diet may protect people from some of the harm of long-term exposure to air pollution, and reduce their risk of dying from heart attacks, stroke and other causes of death, according to new research presented at the ATS 2018 International Conference.
