Oxidative Stress is a condition in which antioxidant levels are lower than normal. Antioxidant levels are usually measured in blood plasma.
A protective function against protein clumping is provided by a heat shock protein within cells.
Scientists have, for the first time, demonstrated the presence of hemoglobin—a protein primarily known for its role in binding with oxygen within red blood cells—in the epidermis, the outermost tissue layer of human skin.
Researchers at the University of São Paulo (USP) in Brazil, partnering with colleagues in Australia, have identified a novel bacterial protein that can keep human cells healthy even when the cells have a heavy bacterial burden.
Researchers at Cincinnati Children’s Hospital reveal how damage to the cell’s energy factory causes muscle wasting. Closing a pore in the mitochondrial membrane in gene-edited mice prevents disease progression.
Could muscadine wine help perk up sagging skin? According to a new study, women who drank two glasses of dealcoholized muscadine wine daily showed significant improvements in the elasticity and water retention of their skin compared with those who consumed a placebo.
Oxidative stress, caused by an imbalance of free radicals and antioxidants, regularly reduces the yield of pharmaceuticals and therapeutics produced via bioprocessing by about 10-15%. Now, Xheme, Inc.'s Xheme Multifunctional Additive (XMA), a programmable non-toxic nanoporous microparticle, has demonstrated the ability to significantly reduce or eliminate the damage of oxidative stress in bioprocessing conditions.
Leishmaniasis is a tropical disease caused by parasites known as Leishmania, which are transmitted to humans and animals through the bites of more than 90 species of sand flies.
Nuclear factor erythroid 2-related factor 2 (NRF2) is a master transcription factor with a role in maintaining oxidative stress response. It can be triggered by both redox-dependent and redox-independent pathways.
A new study finds a chemical formed when we digest a widely used sweetener is "genotoxic," meaning it breaks up DNA.
Antiretroviral cocktails can make human immunodeficiency virus, or HIV, undetectable and untransmittable, but both the virus and its treatment can also accelerate aging of bone and muscle.
A new drug delivery system delivers an antioxidant directly to mitochondria in the liver, mitigating the effects of oxidative stress.
Inhibiting a tiny RNA whose levels significantly increase with age, along with problems like weaker bones and sagging muscles, may be a way to keep our bodies more youthful and healthy, scientists say.
A new research paper was published on the cover of Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 15, Issue 8, entitled, "A chronic wound model to investigate skin cellular senescence."
Ribonucleic acids (RNAs) are single-stranded molecules that are found in all living organisms’ cells. As “transcripts” of human genes, mRNAs, for instance, play a role in the translation of genetic information by bearing the instructions for the production of a protein in their own sequence.
Researchers have discovered that if oxidative stress destroys protein factories known as ribosomes, repair crews may go in to assist in repairing the damage so that production may restart rapidly.
A key enzyme in sugar metabolism is inactivated particularly easily and efficiently by oxidative stress.
Scientists from the Trinity Biomedical Sciences Institute (TBSI) have shed new light on aging processes in the brain.
Researchers at the Department of Chemical Engineering, Indian Institute of Technology, India, have investigated the effects of oxidative stress on the production of monoclonal antibodies (mAbs), and how antioxidants can alleviate this stress to improve their performance.
Biologists at the University of Iowa have conclusively connected epilepsy with the brain’s immune system.
The team of international scientists suggest that it is critical to understand the biochemical, ecological and physiological responses on plants to the stresses of heat and drought in order for more practical solutions and management.
