Do high dietary intakes of trans fats really promote cardiovascular disease?
From his assessment of the studies, Dr John Stanley says the conclusion that trans fatty acids promote cardiovascular disease is premature for the following reasons. First, although prospective cohort studies show an association with cardiovascular disease, trans fatty acids are estimated rather than measured. They may also be markers for some... view more...

pHlight of the mayfly
Ecologists at Cardiff University are using genetic techniques alongside classical ecology to help explain why Welsh streams are not recovering from the biological damage done by acid rain. Speaking at the British Ecological Society’s Winter Meeting, to be held at the University of Warwick on 18–20 December 2001, Ceri Williams will... view more... (2001-12-10)
High levels of uric acid may be associated with high blood pressure
Reducing levels of uric acid in blood lowered blood pressure to normal in most teens in a study designed to investigate a possible link between blood pressure and the chemical, a waste product of the body's normal metabolism. view more (2008-08-27)
Queen's chemist sheds light on health benefits of garlic
Researchers have widely believed that the organic compound, allicin - which gives garlic its aroma and flavour - acts as the world's most powerful antioxidant. But until now it hasn't been clear how allicin works, or how it stacks up compared to more common antioxidants such as Vitamin E and coenzyme Q10, which stop the damaging effects of... view more...

The predominance of heartburn among asthma sufferers led many specialists to suspect that acid reflux could be a trigger for the coughing, wheezing and breathlessness of asthma. view more (2009-04-09)
Caffeic acid inhibits colitis in a mouse model -- is a drug-metabolizing gene crucial?
Researchers at Iowa State University have found that increased expression of a form of cytochrome P-450 (CYP4B1) is a key marker of inhibition of colitis in mice by caffeic acid, an anti-inflammatory antioxidant compound widely distributed in foods. view more (2009-05-27)
Popular stomach acid reducer triples risk of developing pneumonia
A popular stomach-acid reducer used to prevent stress ulcers in critically ill patients needing breathing machine support increases the risk of those patients contracting pneumonia threefold, according to researchers at Wake Forest University School of Medicine. view more (2009-09-14)
Good bacteria can be EZ Pass for oral vaccine against anthrax
Researchers at North Carolina State University have discovered that the good bacteria found in dairy products and linked to positive health benefits in the human body might also be an effective vehicle for an oral vaccine that can provide immunity to anthrax exposure. view more (2009-02-17)
Folic acid, B vitamins do not appear to affect cancer risk
A daily supplementation combination that included folic acid and vitamin B6 and B12 had no significant effect on the overall risk of cancer, including breast cancer, among women at high risk of cardiovascular disease, according to a study in the November 5 issue of JAMA. view more (2008-11-05)
New malaria enzyme laid bare with help of computer calculations
Using only computers, a research team at Uppsala University in Sweden has managed to reveal both the structure and the function of a newly discovered enzyme from the most dangerous malaria parasite, Plasmodium falciparum. All that was needed was the amino acid sequence of the enzyme. The findings may represent a breakthrough for future... view more... (2004-12-07)
Atomic structure of the mammalian 'fatty acid factory' determined
Mammalian fatty acid synthase is one of the most complex molecular synthetic machines in human cells. It is also a promising target for the development of anti-cancer and anti-obesity drugs and the treatment of metabolic disorders. view more (2008-09-05)
Natural plant oil does not improve eczema
Borage oil (sold as starflower oil in chemists and health food shops) does not improve symptoms of eczema, despite some studies suggesting a dose related benefit, finds a study in this week's BMJ. Purified borage oil contains a minimum of 23% gamma linolenic acid (GLA), an essential fatty acid that is needed for normal skin function. Evening... view more... (2003-12-10)
New research shows folic acid in grains has reduced birth defects
Folic acid fortification of grain foods has produced a one-third decline in serious birth defects of the brain and spine, but the March of Dimes urged federal officials to help spare a greater number of babies from these devastating conditions by requiring higher levels of the B vitamin. view more (2005-09-06)

Hopkins Children's study: Folic acid may help treat allergies, asthma
Folic acid, or vitamin B9, essential for red blood cell health and long known to reduce the risk of spinal birth defects, may also suppress allergic reactions and lessen the severity of allergy and asthma symptoms. view more (2009-04-30)
Bone drug could help prevent the spread of breast cancer
Maintaining bone density could be a key to decreasing the spread of cancer in women with locally advanced breast cancer, according to research at Washington University School of Medicine in St. Louis. view more (2008-05-19)
Mortality Rates Reduced among Children Whose Mothers Received Iron-folic Acid Supplements
Offspring whose mothers had been supplemented with iron-folic acid during pregnancy had dramatically reduced mortality through age 7, according to researchers at the Johns Hopkins Bloomberg School of Public Health. view more (2009-10-29)
