This time of year is perfect for catching up on local physiology news. For the next few posts, we are going to take a tour around the country to learn what’s going on in some of the chapters of the American Physiological Society… First stop: the Missouri Physiological Society, otherwise known as “mophys”. Mophys is an independent chapter of the American Physiological Society. They held their annual meeting on September […]
Alzheimer’s disease affects approximately 1 in 9 adults (10.7%) over the age of 65 years (Alzheimer’s Association). Oxidative stress and the progressive loss of cholinergic neurons, which produce the neurotransmitter acetylcholine, are thought to be a major cause of memory loss associated with Alzheimer’s Disease. For this reason, current treatments include efforts to increase levels of acetylcholine in the brain. Medications known as cholinesterase inhibitors help treat memory loss by […]
Most animals that we know of sleep. Sleep is very important for a healthy brain and our brains are important in regulating sleep. Interestingly, recent studies have shown that the cerebrospinal fluid actually washes out toxins from the brain when we get enough sleep at night. That “rinse cycle” so to speak is the brain’s way of staying healthy and is thought to prevent neurodegenerative diseases like Alzheimer’s. You may […]
I am pretty sure most people would agree that dolphins are pretty smart. But did you know that they may develop similar neurological conditions as humans? I read an interesting article published in Drug Target Review exploring how dolphins that have washed up on beaches may help us understand neurological diseases like Alzheimer’s as well as responses to viral infections. For example, Dolphin morbillivirus (DMV) is a virus similar to […]
Check out this video from Reuters (via YouTube). It summarizes an exciting study from researchers at Imperial College London who were able to stop the progression of Alzheimer’s disease in mice by administering a modified virus to the animals. The virus worked by preventing the formation of the characteristic amyloid plaques that are responsible for causing damage to neurons in the brain. Importantly, the virus did not result in loss […]
