OXIDATIVE STRESS

This study tested whether a short course of the steroid prednisone could improve sperm quality in men with infertility caused by inflammation. Researchers measured markers of oxidative stress and sperm health six months after treatment. The trial involved 200 men and compared pre…

This study looked at whether black raspberry lozenges could reduce DNA damage in mouth cells caused by smoking. 69 adult smokers took the lozenges for several weeks. The goal was to see if the berries could lower harmful chemical markers linked to oral cancer. Results may help fi…

This study tested whether a daily supplement made from a mushroom extract (PsP) could reduce markers of oxidative stress and inflammation in 200 adults who smoke or are exposed to smoke. Participants took either PsP or a placebo for 8 weeks, and researchers measured changes in bl…

This study looked at whether drinking hydrogen-rich water can improve performance and recovery in national-level fin-swimmers. Fourteen elite athletes took part in a double-blind, placebo-controlled crossover trial. Researchers measured swimming times, muscle fatigue, and oxidati…

This study tested whether a daily dietary supplement with natural compounds could help reduce skin ageing in 92 healthy adults aged 29 to 82. Participants took either the supplement or a placebo for six weeks. Researchers measured blood markers for collagen production, oxidative …

This study looked at whether taking powdered tart cherries for 10 days helps trained adults recover faster after repeated sprints. Forty healthy men and women took either tart cherry powder or a placebo, then did a series of 30-meter sprints. Researchers measured muscle soreness,…

This study looked at whether a single dose of apple cider vinegar, taken with a meal, changes levels of a substance linked to oxidative stress in the blood of adults with obesity. 46 healthy obese adults were randomly assigned to either receive apple cider vinegar with a standard…

This study looked at whether a natural antioxidant marker in gum tissue can help tell how severe gum disease (periodontitis) is. Researchers measured levels of thioredoxin reductase 1 and other markers in gum samples from 60 healthy people and patients with different stages of gu…

This study looked at how breathing pure oxygen for 30 minutes affects blood flow and stress in the brain, and whether vitamin C can help. Thirteen healthy adults took part, each receiving either vitamin C or a placebo before oxygen. Researchers measured brain blood flow, skin per…

This completed study looked at how the drug deferiprone affects blood cells from 90 people with Parkinson's disease, ALS, or healthy volunteers. Researchers measured markers of oxidative stress and iron levels in the lab. The goal was to better understand these diseases, not to t…

This completed study compared two anesthesia methods—general anesthesia and infraclavicular block—in 106 adults undergoing upper arm surgery with a tourniquet. Researchers measured markers of oxidative stress and blood vessel function to see which method causes less damage. The g…

This study looked at whether people who used a tobacco heating system for at least 2 years had lower levels of harmful chemicals, cell stress, and inflammation in their bodies compared to cigarette smokers. About 974 healthy adults aged 30-60 from Asia and Europe took part. The g…

This study looked at how different oxygen levels during laparoscopic lower abdominal surgery affect stress markers in the lungs and blood. 76 adults were randomly assigned to receive either normal (35%) or high (80%) oxygen during surgery. Researchers measured changes in various …

This study looked at whether using a special laser (Nd:YAG) during root canal treatment could help reduce inflammation and oxidative stress in infected teeth. Researchers measured certain markers in fluid samples from 58 patients. The results showed that the laser did not provide…

This study looked at 140 women who had a C-section to see if the type of anesthesia (general vs. regional) changes the levels of natural antioxidants in their breast milk. Researchers collected a small milk sample 6 hours after surgery. The goal was simply to observe and compare,…

This study looked at how CrossFit and traditional resistance training affect inflammation and oxidative stress in people who don't usually exercise. Twenty-four healthy, untrained adults followed a 12-week program with five sessions per week. Researchers measured blood markers be…

This study looked at blood markers of oxidative stress and antioxidant defenses in 17 elite female cross-country skiers compared to 17 sedentary women. Researchers measured enzymes and molecules that help the body handle exercise-related stress. The goal was to learn how intense …

This study looked at how regular exercise changes certain blood markers linked to oxidative stress in healthy young women aged 18-25. Researchers compared 15 women who exercised at least three times a week for a year with 15 women who did not exercise regularly. They measured two…

This study tested whether using a device called the Oxygen Reserve Index (ORI) to guide oxygen levels during rhinoplasty (nose job) surgery could reduce oxidative stress, a type of cell damage. Sixty healthy adults having rhinoplasty were split into two groups: one received stand…
