Overactive immunity in pregnancy linked to brain damage in offspring

Overactive immunity in pregnancy linked to brain damage in offspringNew York, Feb 9 - The male child may be more vulnerable to brain disorders due to the immune system 'overdrive' in pregnant women than the female child -- and the impact may be life long, a new study shows.

The hippocampus - part of the brain responsible for memory and spatial navigation - was found smaller over the long term in male offspring exposed to the overactive immune system in the womb, said researchers.

In research conducted on male mice, scientists found that the males also had fewer nerve cells in their brains and their brains contained a type of immune cell that should not be present there.


Women lead worse life than men after stroke

Women lead worse life than men after strokeNew York, Feb 8 - Women who survive stroke have a worse quality of life than men, shows research.

"We have found that women had a worse quality of life than men up to 12 months following a stroke, even after considering differences in important socio-demographic variables, stroke severity and disability," said Cheryl Bushnell, associate professor of neurology at Wake Forest Baptist Medical Center in North Carolina.

Researchers compared the quality of life in men and women who had a stroke or transient ischemic attack (TIA).

A total of 1,370 patients aged 56 to 77 were included in the study.


Deceptive protein helping bacteria dodge immune system found

Deceptive protein helping bacteria dodge immune system foundNew York, Feb 7 - A clever protein that helps bacteria misdirect our immune system holds promise for new and effective antibacterial drugs.

Scientists have discovered an unusual bacterial protein, called 'Protein M', that gets attached to virtually any antibody and prevents it from binding to its target.

It probably helps some bacteria evade the immune response and establish long-term infections.


Common cold in pregnancy hikes asthma risk for babies

Common cold in pregnancy hikes asthma risk for babiesNew York, Feb 4 - If you are pregnant and have common cold, it may put your child at risk of having asthma, warns a study.

The more frequently a woman catches common cold and viral infections during pregnancy, the higher the risk of her baby having asthma, it added.

A mother's infections and bacterial exposure during pregnancy affect the environment in the uterus, thus increasing a baby's risk of developing allergy and asthma in childhood.


Switch on blue light to enhance alertness, performance

Switch on blue light to enhance alertness, performanceNew York, Feb 4 - Feeling tired at school or work place? Write to the management to fix blue light in the premises as it increases alertness and performance levels even during daytime.

Researchers have found that blue light exposure may be a counter-measure for fatigue - during the day and night.

“While alertness in night workers has obvious safety benefits, day shift workers may also benefit from better quality lighting that would not only help them see better but also make them more alert,” said Steven Lockley, neuroscientist at Brigham and Women's Hospital (BWH) in Boston, Massachusetts.


15 min-self-administered test may help spot Alzheimer's early

15 min-self-administered test may help spot Alzheimer's earlyWashington, Jan 14 : Researchers have confirmed the feasibility and efficiency of the Self-Administered Gerocognitive Examination (SAGE test), which takes less than 15 minutes to complete.

Memory disorders researchers visited 45 community events where they asked people to take a simple, self-administered test to screen for early cognitive loss or dementia.

Dr. Douglas Scharre, who developed the test with his team at Ohio State, said that of the 1047 people who took the simple pen-and-paper test, 28 percent were identified with cognitive impairment.
