Potential therapeutic target for treating disorders like age-related macular degeneration Conditions like atherosclerosis and age-related macular degeneration (AMD) -- the most common cause of blindness among the elderly in western societies -- are strongly linked to increased oxidative stress, the process in which proteins, lipids and DNA damaged by oxygen free radicals and related cellular waste accumulate, prompting an inflammatory response from the body's innate immune system that...

Cell´s reserve fighting force shrinks with age, new study finds. When the body fights oxidative damage, it calls up a reservist enzyme that protects cells — but only if those cells are relatively young, a study has found. Biologists at USC discovered major declines in the availability of an enzyme, known as the Lon protease, as human cells grow older. The finding may help explain why humans lose energy with age and could point medicine toward new diets or pharmaceuticals...

Published in the Journal of Alzheimer's Disease After more than 100 years following its pathologic description, the cause of Alzheimer's disease (AD) remains unknown. To test the validity of present and future proposals related to the probable cause of AD, three postulates, or necessary conditions, are recommended by Jack de la Torre, MD, PhD, Adjunct Professor of Psychology at the University of Texas, Austin, in an article published in the Journal of Alzheimer's Disease. "Knowing what causes...

Findings could lead to treatments to prevent premature aging and cancer Cells in the human body are constantly being exposed to stress from environmental chemicals or errors in routine cellular processes. While stress can cause damage, it can also provide the stimulus for undoing the damage. New research by a team of scientists at the University of Rochester has unveiled an important new mechanism that allows cells to recognize when they are under stress and prime the DNA repair machinery to...

Discovery could provide new target for drug development against conditions including heart attack, stroke and Parkinson's disease Scientists from the Florida campus of The Scripps Research Institute have uncovered a potentially important new therapeutic target that could prevent stress-related cell death, a characteristic of neurodegenerative diseases such as Parkinson's, as well as heart attack and stroke. In the study, published recently in the journal ACS Chemical Biology, the scientists...

In addition to its damaging effect on the environment and its illegal smuggling into developing countries, researchers have now linked e-waste to adverse effects on human health, such as inflammation and oxidative stress "“ precursors to cardiovascular disease, DNA damage and possibly cancer. In a study published today, Tuesday 31 May, in IOP Publishing's journal Environmental Research Letters, researchers took air samples from one of the largest e-waste dismantling areas in China and...

Bitter cumin is used extensively in traditional medicine to treat a range of diseases from vitiligo to hyperglycemia. It is considered to be antiparasitic and antimicrobial and science has backed up claims of its use to reduce fever or as a painkiller. New research published in BioMedCentral's open access journal BMC Complementary and Alternative Medicine shows that this humble spice also contains high levels of antioxidants. Reactive oxygen species (ROS), also known as free radicals, are...

An impaired ability to handle oxidative stress that arises from exposure to secondhand smoke and other environmental triggers may contribute to the development of asthma, according to results obtained from the Shanghai Women's Health Asthma and Allergy Study. The results of the study suggest regulating the body's antioxidant defense system may play an important role in asthma prevention. The study will be presented at the ATS 2011 International Conference. "We found that the host antioxidant...
