If someone's strength keeps dropping during weight training, that might be the best sign they're overtraining—because no blood test or body measurement has proven to reliably catch it early.
In guys who lift weights a lot, certain chemicals in their urine that show stress on the body are closely linked to both worse performance and more training — meaning they might help tell when...
When guys who lift weights train too much, their body's natural antioxidants take a hit — they lose a lot of the good kind and build up more of the used-up kind, which might be why they start...
If guys who lift weights train too much — like a whole lot in a week — their bodies might get stressed in a way that could hurt their performance, and scientists can see this stress through certain...
If there's a glitch in a gene called Mitf, it might cause the cells that give hair its color to go haywire too early, making animals gray faster as they age.
As we age, the stem cells that give color to our hair can start acting up — they might turn into pigment cells too soon or in the wrong place, which could be why our hair turns gray.
When a certain gene called Bcl2 isn't working right in mice, the stem cells that give rise to hair color die off when hair follicles go dormant, but the actual color-making cells are fine—this leads...
Going gray might happen because the stem cells that keep your hair colored aren't working properly as you age.
Taking a certain dose of CoQ10 every day for six weeks might help lower inflammation in people with moderate to severe kidney disease.
Taking a supplement called nicotinamide riboside for six weeks might help immune cells in people with serious kidney disease work better by boosting their energy levels.
Taking certain supplements like nicotinamide riboside or coenzyme Q10 might help lower signs of body stress in people with serious kidney disease.
Taking a certain dose of CoQ10 for six weeks might change how genes work in people with serious kidney disease, possibly helping with inflammation and metabolism.
Taking a supplement called nicotinamide riboside for six weeks might change how certain genes work in people with moderate to severe kidney disease, possibly helping with energy and metabolism.
In people with moderate to severe kidney disease, taking either nicotinamide riboside or coenzyme Q10 for six weeks seems to change how certain genes work in the blood — one affects energy and fat...
Taking a supplement called nicotinamide riboside every day for six weeks might boost a protein in the blood that affects the immune system in people with moderate to severe kidney disease — but we...
Taking 1200 mg of CoQ10 every day for six weeks might help lower two key markers of inflammation in people with moderate to severe kidney disease, even though one of the markers didn’t stay...
In people with moderate to severe kidney disease, taking 1000 mg of nicotinamide riboside daily for six weeks may boost energy in immune cells, but the same doesn’t happen with a high dose of CoQ10.
Taking certain supplements like nicotinamide riboside or CoQ10 for six weeks might help reduce harmful stress in the body for people with moderate to severe kidney disease.
When stress triggers a chemical called norepinephrine, it can permanently wipe out the stem cells that give hair its color, so once they're gone, your hair can't naturally regain its color.
Your hair color comes from cells in your hair roots, and as you age, those cells slow down — that's why hair turns gray. But new research says things like stress might also play a role.
Stress can turn your hair gray by messing with nerve signals in your hair follicles, which damages the cells that give hair its color — and once they're gone, the graying is permanent.
As we get older, the stem cells that keep our hair colored might stop working properly because of problems in their internal repair system, and once they're gone, our hair turns gray for good.
Too much stress from oxygen-related chemicals in your hair roots might damage the cells that give hair its color, leading to gray hair — especially when stuff like hydrogen peroxide builds up and...
When your hair grows fast, it might stress the cells that give hair its color, causing them to wear out faster and turn hair gray sooner.
