Symposium papers highlight role of oxidative stress in cardiovascular disease

Recent years have seen major advances in understanding of the health effects of oxidative stress—including its potential to cause injury to the cardiovascular system. A series of expert updates on the role of oxidative stress in heart failure, atherosclerosis, and other cardiovascular diseases appears in a special symposium in the August issue of The American Journal of the Medical Sciences, official journal of the Southern Society for Clinical Investigation.

Scientists find distinct links between smoking during pregnancy and long-term harm for the child

Scientists now understand more about why being exposed to nicotine while you were a fetus will increase your risk of developing cardiovascular disease as an adult. "We have found distinct links between cigarette smoking or even using nicotine patches or gum and the long-term harm for the child," says Dr. DaLiao Xiao, a scientist who works at the Loma Linda University School of Medicine in California.

Scientists reveal that 'detox' protein could trigger pancreatic, lung cancer development

CANCER RESEARCH UK scientists have revealed that a 'detox' protein which mops up harmful 'reactive oxygen' in cells could also trigger pancreatic and lung cancer development, according to a study published in Nature, today.

Stresses can change gene expression without DNA sequence change

None of us are strangers to stress of various kinds. It turns out the effects of all those stresses can change the fate of future generation, influencing our very DNA without any change to the underlying sequence of As, Gs, Ts and Cs. Now, researchers reporting in the June 24th issue of Cell, a Cell Press publication, have new evidence that helps to explain just how these epigenetic changes really happen.

Scientists uncover new therapeutic target that could prevent stress-related cell death

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.

Study: E-waste linked to adverse effects on human health

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.

Bitter cumin contains high levels of antioxidants and protects against DNA damage

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.

Mosquito's midgut bacteria can inhibit malaria parasite development

Researchers at the Johns Hopkins Bloomberg School of Public Health have identified a bacterium in field-caught mosquitoes that, when present, stops the development of Plasmodium falciparum, the parasite that causes malaria in humans.

Insight into probiotic bacteria can help improve intestinal disease treatments

The gut may need bacteria to provide a little bit of oxidative stress to stay healthy, new research suggests. Probiotic bacteria promote healing of the intestinal lining in mice by inducing the production of reactive oxygen species, researchers at Emory University School of Medicine have shown.

Breakdown products of thalidomide cause birth defects: New study

Thalidomide may have been withdrawn in the early 1960s for use by pregnant women, but its dramatic effects remain memorable half a century later. Now, researchers have taken a major step toward understanding exactly how thalidomide causes the birth defects.
