Fatigue is the symptom that most significantly impacts the daily lives of long COVID patients, and can affect quality of life more than some cancers, finds a new study led by researchers at UCL and the University of Exeter.

The research, published in BMJ Open , examines the impact of long COVID on the lives of over 3,750 patients who were referred to a long COVID clinic and used a digital app as part of their NHS treatment for the condition.

Patients were asked to complete questionnaires on the app about how long COVID was affecting them—considering the impact of long COVID on their day-to-day activities, levels of fatigue, depression, anxiety, breathlessness, brain fog, and their quality of life.

The researchers found that many long COVID p...

An international team of biotechnologists and neuroscientists has found the mechanism responsible for reducing depression symptoms in patients given two kinds of hallucinogenic compounds. In their mouse study, reported in the journal Nature Neuroscience, the group isolated binding receptors involved in the types of neural plasticity associated with improvements in depression symptoms. The editors at Nature Neuroscience have published a Research Briefing in the same journal issue outlining the work done by the team on this new effort.

For several years, mental health specialists have known that psychedelic drugs like magic mushrooms and LSD can reduce symptoms in patients with chronic depression. But until now, it was not known how such compounds function...

Tinnitus, the ringing, buzzing or hissing sound of silence, varies from slightly annoying in some to utterly debilitating in others. Up to 15% of adults in the United States have tinnitus, where nearly 40% of sufferers have the condition chronically and actively seek relief.

A recent study from researchers at the University of Michigan’s Kresge Hearing Research Institute suggests relief may be possible.

Susan Shore, Ph.D., Professor Emerita in Michigan Medicine’s Department of Otolaryngology and U-M’s Departments of Physiology and Biomedical Engineering, led research on how the brain processes bi-sensory information, and how these processes can be harnessed for personalized stimulation to treat tinnitus.

Her team’s findings were published in JAMA Network Open.

In crisis, the nucleus calls antioxidant enzymes to the rescue. The nucleus being metabolically active is a profound paradigm shift with implications for cancer research.

Summary points

The human nucleus is metabolically active, according to the findings of a new study in Molecular Systems Biology by researchers at the CRG in Barcelona and CeMM/Medical University of Vienna,

In a state of crisis, such as widespread DNA damage, the nucleus protects itself by appropriates mitochondrial machinery to carry out urgent repairs that threaten the genome’s integrity

The findings represent a paradigm shift because the nucleus has been historically considered to be metabolically inert, importing all its needs through supply chains in the cytoplasm

Cancer hijacks cellular metabolism...
