NIH Recherche Médicale - mar, 22/12/2020 - 00:00
Noteworthy NIH advances in basic research include progress in understanding SARS-CoV-2, discovery of an exercise-induced protein that generates new brain cells and improves memory, and a new pain-suppression center in the brain.

Financial problems can be sign of dementia onset

NIH Recherche Médicale - mar, 15/12/2020 - 00:00
Older adults had problems managing financial obligations up to six years before a diagnosis of Alzheimer’s disease or related dementia.

Antibodies and T cells protect against SARS-CoV-2

NIH Recherche Médicale - mar, 15/12/2020 - 00:00
Monkeys with the highest levels of antibodies against SARS-CoV-2, the virus that causes COVID-19, were best protected against reinfection. Immune cells called T cells also helped prevent reinfection.

Stress may awaken dormant cancer cells

NIH Recherche Médicale - mar, 15/12/2020 - 00:00

Molecular changes in the tumors of patients who are exceptional responders to cancer treatments may suggest personalized treatment approaches for cancer patients.

Hormone suppresses hunger in primates and people

NIH Recherche Médicale - mar, 08/12/2020 - 00:00
A hormone called LCN2 suppressed hunger after eating, researchers found, and levels were depressed in people with obesity.

Molecule guides stem cells to damaged brain tissue

NIH Recherche Médicale - mar, 08/12/2020 - 00:00
Scientists altered a molecule that is naturally produced by the body to safely guide stem cells to damaged brain tissue in mice.

Hydroxychloroquine doesn’t benefit hospitalized COVID-19 patients

NIH Recherche Médicale - mar, 24/11/2020 - 00:00
In a final analysis of study data, researchers concluded that the medication hydroxychloroquine provides no benefit to adults hospitalized with COVID-19.

NIH Recherche Médicale - mar, 24/11/2020 - 00:00
Using a life support machine called ECMO shortly after cardiac arrest outside of a hospital improved patients’ chances of survival.

Immune cells trained in the gut protect the brain

NIH Recherche Médicale - mar, 24/11/2020 - 00:00
Researchers found that the brain’s protective membranes are guarded against microbes by immune cells that are trained in the gut.
