One Woman Can Smell Parkinson's Disease Before Symptoms Manifest
from the strange-superpowers dept.
"For most of her life, Joy Milne had a superpower that she was totally oblivious to," reports NPR. Long-time Slashdot reader doug141 explains what happened next:Milne's husband's natural odor changed when he was 31. He was diagnosed with Parkinson's at 45. When Joy walked into a Parkinson's support group, she smelled the same odor on everybody. A Parkinson's researcher tested her with blind samples from early stage patients, late-stage patients, and controls...
NPR tells the story of that test, which took place at the University of Edinburgh with a Parkinson's researcher named Tilo Kunath:[O]ut of all the samples, Joy made only one mistake. She identified a man in the control group, the group without Parkinson's, as having the disease. But many months later, Kunath says, that man actually approached him at an event and said, "Tilo, you're going to have to put me in the Parkinson's pile because I've just been diagnosed."

It was incontrovertible: Joy not only could smell Parkinson's but could smell it even in the absence of its typical medical presentation.

Kunath and fellow scientists published their work in ACS Central Science in March 2019, listing Joy as a co-author. Their research identified certain specific compounds that may contribute to the smell that Joy noticed on her husband and other Parkinson's patients. Joy and her super smelling abilities have opened up a whole new realm of research, Kunath says... Joy's superpower is so unusual that researchers all over the world have started working with her and have discovered that she can identify several kinds of illnesses — tuberculosis, Alzheimer's disease, cancer and diabetes.
Kunath says the ultimate goal is developing a new tool that can detect detect Parkinson's early. "Imagine a society where you could detect such a devastating condition before it's causing problems and then prevent the problems from even occurring."

This is good news, 1/3 less people will die when they read the ventilator stage. But you still don't want to end up at this point of induced coma en ventilation. No mention of the permanent lung and other organ damage that these recoveries face.

Drug Reverses Age-Related Mental Decline Within Days​

Rapid Rejuvenation of Mental Faculties in Aged Mice Implicates Reversible Physiological ‘Blockage’ Behind Age-Related Cognitive Losses

Just a few doses of an experimental drug can reverse age-related declines in memory and mental flexibility in mice, according to a new study by UC San Francisco scientists. The drug, called ISRIB, has already been shown in laboratory studies to restore memory function months after traumatic brain injury (TBI), reverse cognitive impairments in Down Syndrome, prevent noise-related hearing loss, fight certain types of prostate cancer, and even enhance cognition in healthy animals.

In the new study, published Dec. 1, 2020, in the open-access journal eLife, researchers showed rapid restoration of youthful cognitive abilities in aged mice, accompanied by a rejuvenation of brain and immune cells that could help explain improvements in brain function.

“ISRIB’s extremely rapid effects show for the first time that a significant component of age-related cognitive losses may be caused by a kind of reversible physiological “blockage” rather than more permanent degradation,” said Susanna Rosi, PhD, Lewis and Ruth Cozen Chair II and professor in the departments of Neurological Surgery and of Physical Therapy and Rehabilitation Science.

“The data suggest that the aged brain has not permanently lost essential cognitive capacities, as was commonly assumed, but rather that these cognitive resources are still there but have been somehow blocked, trapped by a vicious cycle of cellular stress,” added Peter Walter, PhD, a professor in the UCSF Department of Biochemistry and Biophysics and a Howard Hughes Medical Institute investigator. “Our work with ISRIB demonstrates a way to break that cycle and restore cognitive abilities that had become walled off over time.”

New Class Of Drug Reverses Paralysis In Mice​

US scientists have developed a new form of drug that promotes the regeneration of cells and reversed paralysis in mice with spinal injuries, allowing them to walk again within four weeks of treatment.

The research was published in the journal Science on Thursday, and the team of Northwestern University scientists behind it hope to approach the Food and Drug Administration as early as next year to propose human trials.

Dairy Products
While many of our favourite dishes contain milk or cheese, they may add to your sinus troubles. Some studies show that dairy products have properties that cause your body to produce excess mucus, creating a stuffy, congested nose and making you miserable.

Sugar does too
