NIH Science in Seconds – a weekly roundup of NIH’s research news. Read more about each of the featured news stories below. Week of February 20, 2023: 1. In a two-person NIH-funded study, researchers found that epidural electrical stimulation targeting the cervical sensory nerve roots of the spinal cord restored arm & hand mobility in patients with chronic post-stroke muscle weakness. The stimulation allowed patients to perform complex tasks like using utensils to eat. http://bit.ly/3KtDj53 2. Researchers have known about yeasts’ ability to evade the effects of lethal toxins; however, NIH researchers have identified the gene that helps endure toxins. The gene, KTD1, provides insight to toxin resistance and the discovery will influence future studies on toxins and the effects on humans. http://bit.ly/3YVqPaM 3. A long-acting antiretroviral treatment (LA-ART) given every 4–8 weeks suppressed HIV in people who were previously not virologically suppressed. The findings indicate that long-acting injectable ART can benefit people who face many treatment barriers and are historically underserved. Some of the study participants were those who have historically had decreased access to antiretroviral therapy (ART), including people experiencing housing insecurity, mental illnesses, and substance use disorders. http://bit.ly/3lX8oUD
