If you think your “organic” crops are free of synthetic chemicals, urine for a shock. 😉
In a randomized, single-blind pilot study, researchers found that anticonvulsive epilepsy drug carbamazepine, which is released in urine, can accumulate in crops irrigated with recycled water—treated sewage—and end up in the urine of produce-eaters not on the drugs. The study, published Tuesday in Environmental Science & Technology, is the first to validate the long-held suspicion that pharmaceuticals may get trapped in infinite pee-to-food-to-pee loops, exposing consumers to drug doses with unknown health effects.
It’s a red flag for me when the researchers add an unknown variable right in the middle of the study (they “ran out of vegetables grown with reclaimed water” and used grocery store vegetables instead, which they assumed would be a mix) rather than start the study over, especially when the study is only over the period of two weeks and a relatively small number of participants.
The brains of people with epilepsy appear to react to music differently from the brains of those who do not have the disorder, a finding that could lead to new therapies to prevent seizures, according to research presented at the American Psychological Association’s 123rd Annual Convention.
It’s hard to pin down exactly what makes us remember things. When you see an image, what makes you decide you’ve seen it before? A new study has tackled this question, identifying a group of neurons that participate in the process of identifying images as familiar.
The implants have been used to control certain forms of epilepsy for some time. The side effects are known, which is how the possible use for weight control was discovered.
In a bid to increase treatments for the nation’s 79 million obese adults, the Food and Drug Administration has approved U.S. marketing of an implantable device that stimulates weight loss by manipulating key appetite signals passing between the brain and the gut.
The new device is the Maestro Rechargeable System, manufactured by EnteroMedics of St. Paul, Minn. While the FDA has approved four medications for weight loss in the past 2 1/2 years, the Maestro system is the first weight loss device to be approved since 2007.
Over a year, on average, it increases the weight loss by “about 8.5%” compared to an implant which was turned off. And it worked for about half the people… An overwhelming amount of the weight loss was attributable to factors other than the implant.
Researchers previously reported that a drug used for almost a century to treat trypanosomiasis, or sleeping sickness, reversed environmental autism-like symptoms in mice. Now, a new study suggests that a genetic form of autism-like symptoms in mice are also corrected with the drug, even when treatment was started in young adult mice.
Suramin is not a drug that can be used for more than a few months without a risk of toxicity in humans.
The effect is not permanent. The experimental mice’s autistic behaviours come back once the suramin has disappeared from their bodies. But these are interesting results.
For a very long time now, scientists have viewed Autism Spectrum Disorder (ASD) as a cellular/genetic disorder and relatively recently researchers are now appreciating neuroimmunology as a whole. However, neuroimmunology is still a difficult field to work in, for a variety of reasons, so there is still a lot of potential in the near and distant future. The genetic, molecular, cellular, systems-level perturbations that lead to ASD do in fact underlie every mental disorder. The two are not mutually exclusive and in fact are dependent on one another.
