Evidence of disturbed gene activity in the brain as a result of heart problems. Researchers at the German Center for Neurodegenerative Diseases (DZNE), the University Medical Center Göttingen (UMG) and the German Center for Cardiovascular Research (DZHK) come to this conclusion based on laboratory studies. They consider that they have found a possible cause for the increased risk of dementia in people with heart problems. In mice, a specific drug which is known to affect gene activity alleviated the mental deficits. The involved experts see these results as potential approaches for therapies. The study data are published in the scientific journal EMBO Molecular Medicine.

In Germany, about four million people are affected by what is called “heart failure”: Their heart muscle is too...

Findings may help explain the wide variety in COVID-19 symptoms and aid search for therapies. COVID-19, the disease caused by the pandemic coronavirus SARS-CoV-2, is primarily regarded as a respiratory infection. Yet the virus has also become known for affecting other parts of the body in ways not as well understood, sometimes with longer-term consequences, such as heart arrhythmia, fatigue and “brain fog.”

Researchers at University of California San Diego School of Medicine are using stem cell-derived organoids — small balls of human cells that look and act like mini-organs in a laboratory dish — to study how the ...

In a new study out of University of California San Diego School of Medicine, researchers have identified a universal strain of bacteria derived from healthy human skin that can treat the most common type of eczema, also known as atopic dermatitis.

In the paper published Feb. 22, 2021, in Nature Medicine, the research team investigated the safety and mechanisms of this certain bacteria in a first-in-human, Phase I, double-blinded clinical trial looking to treat people living with eczema. Of the 54 participants, two-thirds reported improvements in their symptoms, including fewer complaints of itchiness and inflammation.

Scientists identify first compound to repair degenerating brain cells in paralyzing disease. Northwestern University scientists have identified the first compound that eliminates the ongoing degeneration of upper motor neurons that become diseased and are a key contributor to ALS (amyotrophic lateral sclerosis), a swift and fatal neurodegenerative disease that paralyzes its victims.

In addition to ALS, upper motor neuron degeneration also results in other motor neuron diseases, such as hereditary spastic paraplegia (HSP) and primary lateral sclerosis (PLS).

In ALS, movement-initiating nerve cells in the brain (upper motor neurons) and muscle-controlling nerve cells in the spinal cord (lower motor neurons) die. The disease results in rapidly progressing paralysis and death.

So...
