Blood-brain barrier damage occurs even with mild head trauma

In a new study of adolescent and adult athletes, researchers at Ben-Gurion University of the Negev, Stanford University and Trinity College in Dublin have found evidence of damage to the brain’s protective barrier, without a reported concussion. For the first time, the researchers were able to detect damage to the blood-brain barrier (BBB), which protects […]

Study finds electronic cigarettes damage brain stem cells

A research team at the University of California, Riverside, has found that electronic cigarettes, often targeted to youth and pregnant women, produce a stress response in neural stem cells, which are critical cells in the brain. Present throughout life, stem cells become specialized cells with more specific functions, such as brain cells, blood cells, or […]

Study finds direct oxidative stress damage shortens telomeres

The same sources thought to inflict oxidative stress on cells—pollution, diesel exhaust, smoking and obesity—also are associated with shorter telomeres, the protective tips on the ends of the chromosomal shoelace. A new study from the University of Pittsburgh, published today in Molecular Cell, provides the first smoking gun evidence that oxidative stress acts directly on […]

DNA damage leads to genetic diseases and cancer

Scientists have reported that many inheritance mutations are caused by DNA damage rather than errors in DNA doubling. The study was conducted by an international research group and published in Nature Genetics. Unfortunately, the reasons for mutations in normal cells that have not been exposed to ultraviolet, smoke or other external mutagens are understudied. According […]
