Foods Rich In Antioxidants May Promote Cancer Growth
2014-07-11 10:05:11

Rebekah Eliason for redOrbit.com – Your Universe Online Around the globe, health conscious people have sought out antioxidant supplements and eaten diets rich in antioxidants for decades in an attempt to live healthy lives for a long time. Surprisingly, recent clinical trials have dashed the hopes of people taking antioxidant supplements to reduce the risk of cancer. In almost all antioxidant trials, there have been no protective effects against cancer. Among several of the trials,...

Duke-NUS Graduate Medical School Singapore Interested in antioxidants? They protect us against aging and cancer. It's one of the reasons we like our green tea and even our broccoli. But there is a new kid on the antioxidant block - uric acid. But wait, you're thinking, doesn't uric acid cause gout? A team in Singapore has recently showed that uric acid is a major intracellular antioxidant, possibly even more important than the antioxidants we try to eat. They also discovered how uric acid...

An antioxidant that targets specific cell structures—mitochondria—may be able to reverse some of the negative effects of aging on arteries, reducing the risk of heart disease, according to a new study by the University of Colorado Boulder. When the research team gave old mice—the equivalent of 70- to 80-year-old humans—water containing an antioxidant known as MitoQ for four weeks, their arteries functioned as well as the arteries of mice with an equivalent human age of just 25 to...

The discovery of an unknown cellular pathway has helped scientists and physicians better understand end-stage liver disease and offers a potential target for new therapeutics A team of researchers in the University of Arizona's College of Pharmacy has discovered a molecular pathway that could be key to creating new therapeutics that would slow or even reverse the progression of end-stage liver disease. Although cirrhosis of the liver is most commonly associated with alcohol or drug...

In the April issue of Experimental Biology and Medicine a multidisciplinary research team led by Drs. Rex Gaskins and Paul Kenis in the Institute of Genomic Biology (IGB) on the campus of the University of Illinois Urbana-Champaign describe their recent work on subcellular redox homeostasis. Intracellular reduction-oxidation reactions underlie a variety of cell functions including energy metabolism, signaling, and transcriptional processes. Due to these crucial roles in regulating normal...

Lee Rannals for redOrbit.com - Your Universe Online Scientists claim they have found a way to accurately predict the lifespan of a worm, meaning fortune tellers should be updating their LinkedIn profiles pretty soon. Researchers, publishing a paper in the journal Nature, say they have found a way to determine an organism’s lifespan by looking at the bursts of activity in the mitochondria, which is part of the cell which generates energy. “Mitochondrial flashes have an amazing...

Why Some Wound Infections Become Chronic Explained By Researchers
2013-12-18 12:50:39

University of California - Riverside UC Riverside's Manuela Martins-Green shows how decreasing levels of 'reactive oxygen species' can break cycle of unhealing wounds Chronic wounds affect an estimated 6.5 million Americans at an annual cost of about $25 billion. Further, foot blisters and other diabetic ulcers or sores account for the vast majority of foot and leg amputations in the United States today. Why does treating chronic wounds cost so much? What complicates chronic wound...

Antioxidant supplements reduce levels of oxygen radicals within chronically infected wounds & weaken biofilm sealing these wounds By controlling levels of reactive oxygen species levels within chronic wounds of genetically modified mouse models., Manuela Martins-Green, Ph.D., of the University of California, Riverside (UC Riverside) was able to normalize conditions and heal the wounds, according to research to be presented on Tuesday, Dec. 17, at the American Society for Cell Biology...

Astronauts Diagnosed With Eye Problems After Returning From Space
2013-12-11 16:34:15

NASA Those who travel to space are rewarded with a beautiful sight – planet Earth. But the effects of space travel on the human sense of sight aren’t so beautiful. More than 30 percent of astronauts who returned from two-week space shuttle missions and 60 percent who spent six months aboard the International Space Station were diagnosed with eye problems. Two recent investigations examined mechanisms that may explain eye changes in spaceflight, help find ways to minimize this health...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
