Lower wealth linked with faster physical and mental aging

NIH Recherche Médicale - mar, 30/06/2020 - 00:00
Older adults with less wealth had sharper declines in many measures of physical and mental health than those with more wealth.

Potent antibodies found in people recovered from COVID-19

NIH Recherche Médicale - mar, 30/06/2020 - 00:00
Although most people who recovered from COVID-19 had low levels of antibodies to SARS-CoV-2 in their blood, researchers identified potent infection-blocking antibodies.

Gut bacteria influence behavior in worms

NIH Recherche Médicale - mar, 30/06/2020 - 00:00
Specific gut bacteria influenced eating decisions in worms by affecting their response to odors. The findings give insight into one way gut microbes may affect behavior.

Signature of virus exposure may help detect liver cancer

NIH Recherche Médicale - mar, 23/06/2020 - 00:00
A blood test that measures people’s exposure to different viruses identified those who later developed liver cancer. The test could play an important role in improving outcomes for patients.

Universal mosquito vaccine tested

NIH Recherche Médicale - mar, 23/06/2020 - 00:00
A small trial showed that a vaccine designed to provide broad protection against mosquito-borne diseases is safe and causes a strong immune response in healthy volunteers.

Unique genomic features of fatal coronaviruses

NIH Recherche Médicale - mar, 23/06/2020 - 00:00
A genomic analysis may help explain why some coronaviruses, like SARS-CoV-2, can be deadly, while others cause only mild illness.

Cancer drug may reduce symptoms of severe COVID-19

NIH Recherche Médicale - mar, 16/06/2020 - 00:00
In patients with COVID-19, off-label use of a cancer drug reduced respiratory distress and over-reactive immune responses. The results were used to inform the design of a clinical trial.

Gut bacteria may contribute to abnormal blood vessel formation

NIH Recherche Médicale - mar, 16/06/2020 - 00:00
People with abnormal clusters of blood vessels in the brain called cavernous angiomas had differences in their gut bacteria. The findings could help lead to new diagnostic tests and treatments.

Hairy human skin generated from stem cells

NIH Recherche Médicale - mar, 16/06/2020 - 00:00
Researchers created hair-growing skin from human stem cells and successfully grafted it to mice.

Largest catalog of human genetic diversity

NIH Recherche Médicale - mar, 09/06/2020 - 00:00
Using DNA from over 140,000 people, researchers created a massive catalog of human genome data, along with tools to understand it.

Blood proteins associated with persistent symptoms after brain injury

NIH Recherche Médicale - mar, 09/06/2020 - 00:00
After mild traumatic brain injury, military veterans with higher blood levels of a protein released by injured neurons were more likely to report long-term symptoms.

Researchers create developmental map of mouse cochlea

NIH Recherche Médicale - mar, 09/06/2020 - 00:00
Scientists mapped how sensory cells develop in the mouse cochlea, a key sound-sensing structure in the inner ear. The findings could help lead to therapies for some forms of hearing loss.

Early results show benefit of remdesivir for COVID-19

NIH Recherche Médicale - mar, 02/06/2020 - 00:00
Early clinical trial results support the use of remdesivir for patients with severe COVID-19 who require supplemental oxygen, but more research is needed to improve outcomes for people with COVID-19.

Beneficial bacteria prevent recurring bacterial vaginosis

NIH Recherche Médicale - mar, 02/06/2020 - 00:00
An experimental treatment for a common infection called bacterial vaginosis significantly reduced the rates of recurrence.

Scientists find new pain-suppression center in the brain

NIH Recherche Médicale - mar, 02/06/2020 - 00:00
Scientists identified a group of neurons in mice that blunt pain within the brain. Such neurons could be promising targets for new non-addictive therapies for chronic pain.

Llama antibody engineered to block coronavirus

NIH Recherche Médicale - mar, 19/05/2020 - 00:00
Based on antibodies isolated from llamas, researchers engineered an antibody that prevented SARS-CoV-2, the virus that causes COVID-19, from entering cells in laboratory experiments.

Repurposed drug combats obesity in mice

NIH Recherche Médicale - mar, 19/05/2020 - 00:00
Obese mice lost weight and showed improved metabolic function when treated with a drug that’s normally prescribed for alcohol use disorder.

Sex differences in autoimmune disorders and schizophrenia

NIH Recherche Médicale - mar, 19/05/2020 - 00:00
A new study suggests that an immune-related protein found in higher levels in men helps protect against certain autoimmune diseases but increases the risk of schizophrenia.

Alzheimer’s gene contributes to blood-brain barrier breakdown

NIH Recherche Médicale - mar, 12/05/2020 - 00:00
Damage to the blood-brain barrier may contribute to the development of Alzheimer’s dementia in people carrying a high-risk gene variation.

New insight into regenerating prostate tissue

NIH Recherche Médicale - mar, 12/05/2020 - 00:00
Progress in understanding how the prostate regenerates after hormone therapy may one day lead to improved therapies for prostate cancer.
