Getting active later in life brings benefits

NIH Recherche Médicale - mar, 19/03/2019 - 00:00
People who were inactive as teens and young adults but increased physical activity in middle age saw the same reduced risk of death as those who stayed active from adolescence onward.

Supportive parenting can reduce child’s anxiety

NIH Recherche Médicale - mar, 19/03/2019 - 00:00
Teaching parents ways to respond to their child’s anxiety may reduce symptoms as well as the standard therapy treatment for childhood anxiety.

Blocking a pathway to heart failure

NIH Recherche Médicale - mar, 19/03/2019 - 00:00
Researchers identified drugs to restore heart muscle function in rodents with heart failure. The findings may help pave the way for a similar approach in people.

Weekend catch-up can’t counter chronic sleep deprivation

NIH Recherche Médicale - mar, 12/03/2019 - 00:00
People with consistent sleep deprivation gained weight and experienced a loss of insulin sensitivity. Weekend “recovery” sleep only seemed to make things worse.

Reduced-calorie diet lowers signs of inflammatory bowel disease

NIH Recherche Médicale - mar, 12/03/2019 - 00:00
Feeding mice cycles of a certain low-calorie diet improved signs of inflammatory bowel disease. Feeding people a similar diet seemed to reduce overall inflammation.

“Intelligent” injection device targets tissues

NIH Recherche Médicale - mar, 12/03/2019 - 00:00
Researchers developed a resistance-sensitive injection device that could help reduce errors when targeting tissues that are difficult to reach using traditional syringes.

Nutrition supplement increases infant birth size

NIH Recherche Médicale - mar, 05/03/2019 - 00:00
Women in lower-income countries who received nutritional supplements before or early in pregnancy were more likely to give birth to healthy-sized babies.

How disrupted sleep may lead to heart disease

NIH Recherche Médicale - mar, 05/03/2019 - 00:00
Researchers found that sleep disruption activates a molecule that triggers inflammation and leads to fatty buildup in mouse arteries.

Doubling the building blocks for DNA

NIH Recherche Médicale - mar, 05/03/2019 - 00:00
Scientists created novel DNA structures from four synthetic and four natural building blocks.

Understanding recurrent tonsillitis

NIH Recherche Médicale - mar, 26/02/2019 - 00:00
In children with recurrent tonsillitis, the bacteria that cause the disease trick immune cells into destroying each other instead of remembering the bacteria.

Blocking DNA repair restores sensitivity of brain tumors to treatment in mice

NIH Recherche Médicale - mar, 26/02/2019 - 00:00
Researchers found that blocking DNA repair made gliomas, a type of deadly brain tumor, more responsive to radiation therapy in mice. The study suggests possible treatment strategies.

Spongy stomach sensor that could be swallowed

NIH Recherche Médicale - mar, 26/02/2019 - 00:00
Engineers designed a sensor-containing device that can quickly inflate with fluid in the stomach and then shrink on demand. The device could make it possible to monitor conditions in the stomach and deliver slow-release drugs.

Intensive blood pressure control may lessen cognitive loss

NIH Recherche Médicale - mar, 12/02/2019 - 00:00
In a study of older adults with a high risk for heart disease, intensive blood pressure control reduced the risk of developing mild cognitive impairment.

Decoding the variety of human antibodies

NIH Recherche Médicale - mar, 12/02/2019 - 00:00
Researchers genetically sequenced antibodies in people’s blood and estimated that the body may be able to make up to one quintillion unique antibodies.

Immune cells in the gut slow metabolism

NIH Recherche Médicale - mar, 12/02/2019 - 00:00
A type of immune cell found in the mouse gut slows metabolism and raises the risk of diabetes and heart disease. Targeting these cells in people might affect obesity and related diseases.

Light activity may lower harmful effects of sitting

NIH Recherche Médicale - mar, 05/02/2019 - 00:00
A study found that even light-intensity movement for 30 minutes a day can reduce the risk of death incurred by sitting.

Ebola antibody treatment tested in people

NIH Recherche Médicale - mar, 05/02/2019 - 00:00
A treatment for Ebola developed from a survivor’s protective antibody was found safe in a study of healthy volunteers at the NIH Clinical Center.

Cerebellum connects to brain’s reward system

NIH Recherche Médicale - mar, 05/02/2019 - 00:00
A study in mice found that the brain’s cerebellum—known to play a role in motor coordination—also helps control the brain’s reward circuitry.

Blood-brain barrier test may predict dementia

NIH Recherche Médicale - mar, 29/01/2019 - 00:00
A new study suggests that measuring the breakdown of the blood-brain barrier could be an early way to test for cognitive impairment from Alzheimer’s disease and other causes.

Printed scaffolds promote spinal cord repair in rats

NIH Recherche Médicale - mar, 29/01/2019 - 00:00
Researchers used 3D printing technology to create a scaffold that helped promote the growth of new nerve cells in rats and restore some limb movement after spinal cord injury.
