This "new generation" antidepressant, fluoxetine (Prozac®) could also restore youth to neurons that inhibit aging, reveal this work by the Picower Institute for Learning and Memory, MIT (Cambridge), conducted in mice and published in the Journal of Neuroscience.Cognitive loss caused more by the loss of plasticity than the loss of cells: the common belief would indeed be that the loss of...
HEALING: A single drop of blood brings cells to attention
A single drop of blood brings cells to attention Several studies have already attempted to visualize the cellular ballet that starts after an injury and at the start of the healing process. This study from the Universities of Oslo and Eindhoven shows how a single drop of blood induces skin cells to align, and how this first connection between cells precedes a much more pronounced collective and...
OBESITY: Male, female, apple or pear?
If we compare, in terms of obesity, body silhouettes, “pears are healthier than apples”, concludes this study from University of California – Riverside. Data that is addressed here more specifically to each sex: because in women, fat generally accumulates around the hips, giving a pear-shaped silhouette, in men, fat tends to accumulate around abdomen, creating an apple shape. This...
MICROBIOTA: Obesogenic household disinfectants for children
Household cleaning products can contribute to overweight children, reveals this Canadian study presented in the Canadian Medical Association Journal (CMAJ). By modifying the intestinal microbiota of children, these disinfectants disrupt their metabolic balance and thus increase the risk of obesity. It is the analysis of the intestinal flora of 757 infants aged 3 to 4 months, with regard...
BLOOD PRESSURE: The surface patch that monitors it in depth
And this patch from the University of California – San Diego monitors blood pressure “deep inside the body”, explains this team from the University of California, San Diego in the journal Nature Biomedical Engineering. A new non-invasive and, above all, continuous monitoring mode that will make it possible to detect cardiovascular problems earlier and with greater precision. The patch...
DIETARY FIBER: Calms the brain during aging
Less age-related brain inflammation with regular dietary fiber intake, says this University of Illinois study adds a new health benefit of these nutrients. Here, it is precisely on immune cells in the brain known as microglia that the fibers exert their effects, thus helping to reduce age-related cognitive decline. Benefits documented in the journal Frontiers in Immunology mainly linked...
MEDICAL CANNABIS: On its broad-spectrum efficacy
This study from the University of New Mexico (Albuquerque) documents the effectiveness of medical cannabis in the treatment of a wide range of health problems, through two studies, presented in the journals Medicines and Frontiers in Pharmacology. Researchers here use a mobile app to identify and track patients' symptom relief and see in the field that medical cannabis immediately relieves...
HYPERACTIVITY: What if ADHD announced a risk of Parkinson's?
This team from the University of Utah suggests attention deficit hyperactivity disorder (ADHD) as a key to identifying future risk for Parkinson's disease. While 10-11% of children are diagnosed with ADHD, the very long-term effects of the disorder, and its drug treatment, remain understudied. This team confirms that people with ADHD in childhood have an increased risk of developing...
PARKINSON: Being able to track dopamine in the brain
These tiny sensors, which can track dopamine in the brain for more than a year, will be invaluable in monitoring patients with Parkinson's disease and other neurological diseases. It is an “invention” by a team from the Massachusetts Institute of Technology (MIT) and a feat, because these sensors can remain in place for several months. Monitoring dopamine levels could help doctors...
