Household chores may help lower Alzheimers risk

LONDON: Being engaged in mundane household chores like cooking, cleaning and washing dishes could help reduce the risk of Alzheimers disease even in those over 80 years of age, a ne

w study has claimed.

The study, which was published in the journal Neurology, included 716 dementia- free men and women in their 70s and 80s who had to wear a device to monitor their daily activities. They were also given cognitive tests to measure memory and thinking ability. After around three years, 71 of the volunteers developed Alzheimers disease, and it was found that the least active were more than twice as likely to develop the disease as those who were most active, the Daily Mail reported. ” The results of our study indicate that all physical activities, including exercise as well as other activities such as cooking, washing the dishes, and cleaning are associated with a reduced risk of Alzheimers disease,” said study author Dr Aron Buchman of Rush University Medical Center in Chicago. ” These results provide support for efforts to encourage all types of physical activity even in very old adults who might not be able to participate in formal exercise, but can still benefit from a more active lifestyle.” Scientists locate malaria parasitesalt39 Achilles heal LONDON: Scientists have identified a key protein common to malaria parasites, opening the way to more effective vaccines or drugs against the life- threatening infections caused by the micro- organisms. The protein has sticky properties that enable it to bind to red blood cells among humans and other animals and form dangerous clumps that can block blood vessels. These clumps can cause severe illness, including coma and brain damage.

Scientists from the University of Edinburgh worked with researchers from Cameroon, Mali, Kenya and the Gambia to test their antibodies against the parasites collected from patients, the journal Public Library of Science Pathogens, reports. Alexandra Rowe, professor at the Edinburgh School of Biological Sciences, who led the study, said: ” We knew that clusters, or rosettes, of blood cells were found in many cases of severe or lifethreatening malaria, so we looked at rosette- forming parasites and found a common factor that we could target with antibodies.” ” We hope this discovery will inform new treatments or vaccines to block the formation of rosettes and prevent many life- threatening cases of malaria,” added Rowe, according to an Edinburgh statement.

Women with heart disease likely to have girls TEHRAN: Women with some heart disease are more likely to give birth to girls, says a study conducted by a university in Iran. It found that 75 percent of the 216 children born to 200 pregnant women with diagnosed heart diseases were girls. ” We believe that this is the first study looking at the relationship between gender and the mothers cardiac disease,” A. Alizadehasl of Tabriz University said in a statement. ” We hope that this will lead to further investigation into this area.” Sixty- four percent of the pregnant women in the study group were diagnosed with valvular disease ( involving one or more of the heart valves), 19 percent had dilated cardiomyopathy ( heart unable to pump blood efficiently) while 14 percent had uncorrected or significant residual congenital heart disease ( defect in the hearts structure and great vessels present at birth).

Omega- 3 fatty acids limit smoking damage ATHENS: Omega- 3 polyunsaturated fatty acids, commonly found in marine and plant oils, could help limit damage caused by smoking, says a new study from Greece. The study assessed the effect of four- week oral treatment with two grams daily of Omega- 3 fatty acids on arterial health of cigarette smokers. The results showed that short- term treatment with the fish oil improves arterial stiffness and minimises the acute smoking- induced damage to arterial elasticity. Omega- 3 fatty acids are fats commonly found in marine and plant oils. In nutrition, polyunsaturated fat, or po
