Vitamin KVitamin K is an enzyme that is important for blood clotting (the process of stopping the flow of blood by clot formation), which is critical for healing damaged blood vessels. If you have a vitamin K deficiency, it might be difficult to stop bleeding from ruptured vessels, including nosebleeds.Besides increased risk of nosebleeds, other signs of vitamin K deficiency include easily bruised skin and muscles, bloody stool, and pale skin.

Sugar substitutes add sweetness with little effect on blood sugar, helping manage blood sugar levels.Natural options like stevia, monk fruit and allulose are low-calorie and gentle on blood sugar.Artificial sweeteners like sucralose and aspartame can be safe in moderation but may affect gut health. Blood sugar is a hot topic in the nutrition world—and for good reason. About 100 million Americans have prediabetes, which means they have elevated blood sugar levels that are not quite high enough to be classified as diabetes. Another 38 million people in the U.S. are living with diabetes. Whether you’re managing a diagnosis or aiming…

Expression of ncAA bearing proteinsChemically competent E. coli K12 cells were co-transformed with pBAD_POI (encoding the POI with a C-terminal H6 tag) and pEVOL_PylRS (encoding two copies of the PylRS variant and tRNACUA). After recovery in 1 ml SOC medium for 1 h at 37 °C, cells were cultured in 5 ml of 2-YT medium supplemented with ampicillin (100 µg ml−1) and chloramphenicol (50 µg ml−1) and grown overnight at 37 °C. The overnight culture was then diluted to an OD600 of 0.05 in either 2-YT or AI media52 supplemented with ampicillin (100 µg ml−1), chloramphenicol (50 µg ml−1) and ncAA. Cells grown in 2-YT medium were grown to an OD600 of 0.6…

Researchers at King’s College London, UK, have published the “first-ever” evidence-based dietary guidelines for adults with chronic constipation. It includes kiwifruits, rye bread, high-mineral-content water, and supplements like psyllium fiber, magnesium oxide, and certain probiotic strains. The more common and widely recommended approaches to this bowel issue are too generic — eat high-fiber diets — or lack strong evidence of effectiveness for senna supplements, a type of laxative, note the researchers. Additionally, they critique common clinical guidelines for being limited and sometimes outdated with dietary recommendations, which typically focus on increasing dietary fiber and fluid intake.The guidelines published in the Journal…

New research led by scientists from the RIKEN Center for Brain Science points to astrocytes as the brain cells responsible for long-term learning and memory. In a new Nature paper, they demonstrate how emotionally intense experiences like fear in mice make their mark on small groups of astrocytes for several days, allowing them to re-engage when the mice recall the experience. Full details are provided in the paper titled “The astrocytic ensemble acts as a multiday trace to stabilize memory.” According to the paper, the team led by Jun Nagai, PhD, a principal investigator at RIKEN, investigated the activity of…

McGill study shows digital cognitive exercises can rejuvenate brain chemistry linked to memory and attention. For years, the idea that a digital ‘brain game’ could do more than mildly entertain or pass the time between Wordle rounds has been met with polite skepticism. Yet a new study from McGill University’s Montreal Neurological Institute – The Neuro – has revealed that targeted, computer-based brain exercises can do something no medication has yet achieved: restore the brain’s acetylcholine system, which underpins attention, memory and learning, to a level typically seen in people a decade younger. The INHANCE clinical trial, published in JMIR…
