OXIDATIVE STRESS

This study tests whether a natural substance called red propolis can lower inflammation and oxidative stress in people with chronic kidney disease (stages 3-5) who are not yet on dialysis. Researchers will measure changes in inflammatory markers like IL-6 and TNF-α. The goal is t…

This study tests whether taking royal jelly supplements can reduce inflammation and slow cell aging in people with chronic kidney disease who are on hemodialysis. Thirty participants will take either royal jelly or a placebo daily for two months. Researchers will measure changes …

This study looks at whether eating wild blueberries can improve heart health, thinking skills, and gut bacteria in Black and White adults aged 45-65 with high blood pressure. Participants will eat blueberries daily and have their blood pressure, artery stiffness, and cognitive fu…

This study tests whether a daily dose of freeze-dried wild blueberry powder can improve blood sugar, blood pressure, and brain function in women with prediabetes. Thirty overweight women aged 20-65 will take either the blueberry powder or a placebo for six weeks. Researchers will…

This study looks at whether drinking a daily serving of gazpacho, a cold tomato-based soup, can improve semen quality in men with low sperm counts or poor sperm movement. Eighty men will follow a Mediterranean diet for 12 weeks, with half also drinking gazpacho each day. Research…

This study is testing whether taking ginger capsules daily for 60 days can lower inflammation and oxidative stress in adults with excess body fat. Fifty participants will be randomly assigned to receive either ginger or a placebo. The goal is to see if ginger can improve markers …

This study looks at whether drinking haskap berry juice helps reduce inflammation and muscle damage after an intense leg workout. Thirty adults who regularly squat will drink either haskap juice or a placebo and follow a special diet. Researchers will measure strength, soreness, …

This study looks at whether high uric acid levels (hyperuricemia) are linked to more severe gum disease and bone loss. Researchers will measure inflammation and oxidative stress markers in gum fluid and blood from 80 adults. Participants are grouped by gum health and uric acid st…

This study looks at whether breathing oxygen in a pressurized chamber after a hard bike ride helps competitive cyclists recover and perform better the next day. Healthy male road cyclists aged 18 to 40 who compete at the national level in Belgium are randomly assigned to differen…

This study looks at how smoking little cigars affects levels of harmful chemicals called oxidants in the body. Researchers will compare three types of smoking: high-oxidant little cigars, low-oxidant little cigars, and regular cigarettes. Fifty daily smokers will provide breath, …

This study looks at how changes in brain blood flow affect breathing control during sleep in healthy adults. Researchers will expose participants to normal oxygen and low oxygen levels to see how the brain responds. The goal is to better understand sleep apnea and related conditi…

This observational study follows 30 women undergoing DIEP flap breast reconstruction after mastectomy. Researchers will measure inflammation and oxidative stress markers in blood samples taken before and after surgery. The goal is to understand how the body responds to the tempor…

This study is looking at new blood markers that measure inflammation and oxidative stress in people with Gaucher disease type 1. Researchers want to see if these markers can give more information than the tests currently used. The study involves 34 adults who are stable on their …

This study tests whether drinking a ginger-based beverage every day can reduce inflammation and improve markers of heart health in adults with excess body fat. Researchers will measure changes in blood markers like interleukins and cholesterol. The study involves 50 participants …

This study is collecting blood, urine, and breath samples from 280 adults—including those with metal allergies and healthy volunteers—to see if exposure to heavy metals and pollutants leaves distinct biological markers. Researchers will compare levels of metals, lung function, an…

This University of California, Davis study is testing whether chocolate made from chardonnay grape leftovers (called marc) can improve blood vessel function and reduce oxidative stress. Five adults with higher body weight and slightly reduced blood vessel flexibility will eat dif…

This study looks at how oxidative stress—a type of cell damage—in both women and men affects the success of in vitro fertilization (IVF). Researchers will measure oxidative stress markers in blood, egg follicle fluid, and sperm from 1,100 couples. The goal is to see if higher oxi…

This study looks at how difficult childhood experiences and poor sleep might harm blood vessel function in young adults aged 18-29. Researchers will monitor sleep at home and test blood vessel health. Some participants will receive a 6-week sleep therapy program (CBT-i) to see if…

This study looks at whether early life adversity (like abuse or neglect) damages blood vessel function in young adults ages 18-29. Researchers will give participants a single dose of MitoQ, a supplement that targets cell energy centers, to see if it reduces stress-related damage.…

This study is for people with diabetic macular edema, a condition that causes vision loss. Researchers want to see if certain substances in the blood and patterns on eye scans can predict how well a patient will respond to two common treatments: anti-VEGF injections or a dexameth…

This study compares two widely used inhaled anesthetics, isoflurane and sevoflurane, to see which one causes less oxidative stress (a type of cell damage) in patients having gallbladder removal surgery. Researchers will measure stress markers in the blood of 80 healthy adults. Th…
