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.

Alzheimer’s patients tend to have differed and increased genetic changes, says study

Errors present in DNA can get accumulated inside brain cells as one is aging. However, in patients with Alzheimer’s disease, these errors called somatic mutations may increase at a quicker rate.

Globins in the body help fight liver disease

Anti-fibrotic therapy is still a medical necessity in the treatment of chronic liver disease in humans. The anti-fibrotic activity of globin family members in hepatic stellate cells (HSCs), the principal cell type involved in liver fibrosis, was reported by a research group led by Professor Norifumi Kawada of Osaka Metropolitan University (OMU).

Immune cells in arteries can sniff out their surroundings and cause inflammation

An artery is not like a nose. Or is it? Scientists at La Jolla Institute for Immunology (LJI) have discovered that immune cells in arteries can "sniff" out their surroundings and cause inflammation.

A highly effective protection against oxidative stress developed by present-day humans

Very few proteins in the body have a change that makes them unique compared to the corresponding proteins in Neanderthals and apes. Researchers at the Max Planck Institute for Evolutionary Anthropology in Germany and Karolinska Institute in Sweden have now studied one such protein, glutathione reductase, which protects against oxidative stress.

Study identifies a novel role for regulatory protein Bach1 in Parkinson's disease

Parkinson's disease (PD) is the most common neurodegenerative movement disorder, afflicting more than 10 million people worldwide and more than one million Americans. While there is no cure for PD, current therapies focus on treating motor symptoms and fail to reverse, or even address, the underlying neurological damage.

Stem cell therapy for heart disease enhanced with protein from fetal heart

The human heart, upon aging, slowly loses its capability to repair itself after injury. Damage caused by injuries like heart attack and cardiac ischemia—linked to decreased oxygen levels in the heart—can result in below normal capacity of heart functioning, making it tough for the patients to carry out daily activities.
