Credit: CDC One thousand confirmed cases of monkeypox, an infectious disease originating in Africa, have been recorded since early May across at least 30 non-endemic countries such as the United Kingdom, … Read more
Patients with Alzheimer’s disease (AD) have lower levels of the neuromodulator acetylcholine (ACh) in their brains. Donepezil, an AD drug, increases brain ACh levels and improves AD-associated learning deficits. Now, researchers have identified the intracellular signal cascade through which ACh regulates aversive learning, a major preliminary test for AD drugs. Researchers also found that donepezil … Read more
Credit: CC0 Public Domain. In 2019, about 463 million people suffered from diabetes and over 2 million people lost their lives to its complications, including common cardiovascular complications such as heart attacks and strokes. We need to discover new ways to combat diabetes and its complications to improve the quality of life and prolong the … Read more
The monkeypox virus has mutated at a far faster rate than would normally be expected and likely underwent a period of “accelerated evolution,” a new study suggests. The virus, which has infected more than 3,500 people in 48 countries since its detection outside Africa in May, may be more infectious due to dozens of new … Read more
A new study finds that flu vaccination was associated with a 40% reduced risk for Alzheimer’s disease over a four-year period. Over the course of four years, those who received at least one influenza vaccine were 40% less likely than their non-vaccinated peers to acquire[{” attribute=””>Alzheimer’s disease, according to a new study from the University … Read more
New recommendations published in the European Journal of Preventive Cardiology describe how to use genetic testing to prevent sudden cardiac death in athletes and enable safe exercise. Recommendations on how to use gene testing to prevent sudden cardiac death in athletes and enable safe exercise were published on June 16, 2022, in the European Journal … Read more
New research shows women who have had a miscarriage or stillbirth, have an increased risk of stroke – when blood can not get to the brain, because of a blocked or burst artery. That risk increases with each miscarriage or stillbirth. Trying to establish this link is difficult because it requires following a large number … Read more
A type of poliovirus derived from vaccines has been detected in London sewage samples, the World Health Organization and British health officials said Wednesday, adding that more analysis was underway. No human cases of polio have been found in Britain, where the crippling disease was fully eradicated two decades ago. The WHO said in a … Read more
MIT chemists have used nuclear magnetic resonance (NMR) spectroscopy to reveal how two different forms of the Tau protein mix to form the tangles seen in the brains of Alzheimer’s patients. Credit: Aurelio Dregni / Nadia El-Mammeri / Hong Lab at MIT Two types of tau proteins mix together in a nearly random way to … Read more
Typhoid fever might be rare in developed countries, but this ancient threat, thought to have been around for millennia, is still very much a danger in our modern world. According to new research, the bacterium that causes typhoid fever is evolving extensive drug resistance, and it’s rapidly replacing strains that aren’t resistant. Currently, antibiotics are … Read more
