Gut bacteria could be responsible for side effect of Parkinson's drug

Bacteria in the small intestine can deaminate levodopa, the main drug that is used to treat Parkinson's disease. Bacterial processing of the unabsorbed fractions of the drug results in a metabolite that reduces gut motility. These findings were described in the journal BMC Biology on 20 October by scientists from the University of Groningen. Since the disease is already associated with constipation, processing of the drug by gut bacteria may worsen gastrointestinal complications.

Unhealthy behaviors trigger same brain responses as bad smells

Unhealthy behaviors trigger moral judgments that are similar to the basic emotions that contribute to our ability to survive. Two hypotheses are prevalent in the current scientific literature as to the identity of these emotions. Some researchers single out disgust, while others opt for pain. After developing a new approach to brain imaging, a research team from the University of Geneva (UNIGE) has come down on the side of disgust. The study, which can be found in Science Advances, shows that unhealthy behaviors trigger brain responses that are similar to those prompted by bad smells. The research also identifies for the first time a biomarker in the brain for disgust.

CBD helps reduce lung damage from COVID by increasing levels of protective peptide
