When performing resistance training such as lifting weights, there’s a lot of interest in how close you push yourself to failure – the point where you can’t do another rep – and how it affects your results. While research has looked at this concept in different ways, to date, no meta-analysis has explored the pattern (i.e., linear or non-linear) of how the distance from failure (measured by repetitions in reserve) affects changes in muscle strength and size. As such, it’s ...

Neurotransmitter levels in the brain can indicate brain health and neurodegenerative diseases like Alzheimer’s. However, the protective blood-brain barrier (BBB) makes delivering fluorescent sensors that can detect these small molecules to the brain difficult. Now, researchers in ACS Central Science demonstrate a way of packaging these sensors for easy passage across the BBB in mice, allowing for improved brain imaging. With further development, the technology could help advance Alzheimer’s disease diagnosis and treatment. It is common for neurotransmitter levels ...

Millions of Americans take anticoagulants, commonly known as blood thinners. These medications work to prevent blood clots that cause heart attack and stroke.  More than two-thirds of those people take a type of blood thinner called a direct oral anticoagulant. DOACs, such as rivaroxaban (brand name Xarelto) and apixaban (brand name Eliquis), are under- or over-prescribed in up to one in eight patents. These prescribing issues can have life threatening consequences, and they most often occur after a provider writes the initial prescription, according to a study led by Michigan Medicine.  “Direct oral anticoagulants may be viewed ...

ROCHESTER, Minn. — Mayo Clinic scientists are using artificial intelligence (AI) and machine learning to analyze electroencephalogram (EEG) tests more quickly and precisely, enabling neurologists to find early signs of dementia among data that typically go unexamined. The century-old EEG, during which a dozen or more electrodes are stuck to the scalp to monitor brain activity, is often used to detect epilepsy. Its results are interpreted by neurologists and other experts trained to spot patterns among the test's squiggly waves. In new research published in Brain Communications, scientists at the Mayo Clinic Neurology AI Program (NAIP) demonstrate ...
