A new study published in the journal of Minerva Cardioangiologica says that Pycnogenol, pine bark extract from the French maritime pine tree, reduces jetlag in passengers by nearly 50 percent. The two-part study, consisting of a brain CT scan and a scoring system, showed Pycnogenol lowered symptoms of jetlag such as fatigue, headaches, insomnia and brain edema (swelling) in both healthy individuals and hypertensive patients. Passengers also experienced minimal lower leg edema, a common condition associated with long flights.
Jetlag, also called desynchronosis, is a temporary disorder…
Consuming caffeine at any time during pregnancy is associated with an increased risk of fetal growth restriction (low birth weight), according to research published on bmj.com today.
Although some previous studies have also shown this, the study additionally shows that any amount and type of caffeine intake — from tea, cola, chocolate, cocoa, and some prescription drugs, as well as coffee—is linked with relatively slower fetal growth.
Dr Justin Konje and colleagues from the University of Leicester as well as collaborators from the University of Leeds, examined the association of…
Consuming foods rich in polyphenols from grapes, including red wine, helps reduce the risk of heart disease, according to a review article in the November issue of Nutrition Research.
The authors review the accumulating evidence that grape polyphenols work in many different ways to prevent cardiovascular and other "inflammatory-mediated" diseases. Polyphenols are natural antioxidants found in grapes and some other plant foods. Their types and actions vary, depending on where in the grape they are found. Grape seeds, grape skin, and grape juice contain several types of polyphenols, including…
Could eating grapes help fight high blood pressure related to a salty diet? And could grapes calm other factors that are also related to heart diseases such as heart failure? A new University of Michigan Cardiovascular Center study suggests so. The new study published in the October issue of the Journal of Gerontology: Biological Sciences outlines the potential of grapes in reducing cardiovascular risk. The effect is thought to be due to the high level of phytochemicals – naturally occurring antioxidants – that grapes contain.
The study was performed in laboratory rats, not…
Patients treated for their prolonged seizures with the sedative propofol may be at high risk for complications and even death. New research presented at CHEST 2008, the 74th annual international scientific assembly of the American College of Chest Physicians (ACCP), shows that the use of propofol as an antiepileptic agent in patients with refractory status epilepticus (RSE), prolonged seizures that do not respond to initial treatment, was associated with significant mortality and morbidity.
RSE is a difficult clinical problem seen in patients with primary epilepsy and in those with…
A study has found that the risks of a premature birth quadruple if flaxseed oil is consumed in the last two trimesters of pregnancy. The research was conducted by Professor Anick Bérard of the Université de Montréal's Faculty of Pharmacy and the Sainte-Justine Hospital Research Center and Master's student Krystel Moussally.
The correlation existed only with flaxseed oil. Women consuming the actual seed were unaffected.
In Canada, 50 percent of pregnant women take prescription medication. Yet many of them prefer to use natural health products during the pregnancy. "We believe…
A University of Iowa study suggests that the prolonged fatigue after mild exercise that occurs in people with many forms of muscular dystrophy is distinct from the inherent muscle weakness caused by the disease.
The research, which is published in Nature Advance Online Publication Oct. 26, identifies a faulty signaling pathway that appears to cause exercise-induced fatigue in mouse models of muscular dystrophy. Moreover, the study shows that Viagra can overcome the signaling defect and relieve the fatigue. The findings suggest that targeting the signaling pathway may lead to therapies for…
According to trials, a new obesity drug, Tesofensine can produce weight loss twice that of currently approved obesity drugs.
Increased obesity prevalence worldwide, in both developed and developing countries, results in more people with cardiovascular disease, diabetes, musculoskeletal disorders, and cancer. Whilst gastric bypass surgery substantially reduces bodyweight and obesity-related disease, the researchers believe a treatment gap exists between the effectiveness of currently marketed obesity drugs and gastric-bypass surgery. Tesofensine – which inhibits the presynaptic uptake of the…
A powerful antioxidant in green tea may prevent or delay the onset of type 1 diabetes, Medical College of Georgia researchers say.
Researchers were testing EGCG, green tea's predominant antioxidant, in a laboratory mouse with type 1 diabetes and primary Sjogren's syndrome, which damages moisture-producing glands, causing dry mouth and eyes.
"Our study focused on Sjogren's syndrome, so learning that EGCG also can prevent and delay insulin-dependent type 1 diabetes was a big surprise," says Dr. Stephen Hsu, molecular/cell biologist in the School of Dentistry. They found it also…

The MS Society in the UK has responded to today's embargoed announcement from the University of Cambridge relating to the alemtuzumab MS study results.
The study has found that alemtuzumab potentially stops MS from advancing in people with early stage active relapsing-remitting multiple sclerosis (RRMS) and may also restore lost function caused by the condition. The findings will be published in the New England Journal of Medicine.
Multiple sclerosis is the most common disabling neurological condition affecting young adults and an estimated 85,000 people in the UK have MS. MS is the…
