Study links abnormally high blood sugar with higher risk of death in COVID-19 patients not previously diagnosed with diabetes
New research from Wuhan, China shows that, in patients with COVID-19 but without a previous diagnosis of diabetes, abnormally high blood sugar is associated with more than double the risk of death and also an increased risk of severe complications.
Study pinpoints brain cells that trigger sugar cravings and consumption
New research has identified for the first time the specific brain cells that control how much sugar you eat and how much you crave sweet tasting food. The study specifically identifies the brain cells that respond to the hormone FGF21 to regulate sugar intake and sweet taste preference.
Extraordinary regeneration of neurons in zebrafish
Biologists have discovered a uniquely rapid form of regeneration in injured neurons and their function in the central nervous system of zebrafish. They studies the Mauthner cells, which are solely responsible for the escape behavior of the fish, and previously regarded as incapable of regeneration. However, their ability to regenerate crucially depends on the location of the injury.
Global COVID-19 registry finds strokes associated with COVID-19 are more severe have worse outcomes and higher mortality
Patients with COVID-19 who have an acute ischemic stroke (AIS) experience more severe strokes, have worse functional outcomes and are more likely to die of stroke than AIS patients who do not have COVID-19. The wide range of complications associated with COVID-19 likely explain the worse outcomes.
