Sleep Loss Detrimental to Blood Vessels

Lack of sleep has previously been found to impact the activation of the immune system, inflammation, carbohydrate metabolism and the hormones that regulate appetite. Now University of Helsinki researchers have found that sleep loss also influences cholesterol metabolism.

Sleep Tight, Fruit Fly – Scientists Find Gene Responsible for Sleep Deprivation and Metabolic Disorders

keene-alex-fau.jpg

Like humans, fruit flies sleep at night, caffeine affects their sleep, and if they get a lousy night’s sleep it can affect their memory performance. But what can they tell us about the connection between sleep deprivation and metabolic disorders like diabetes and obesity? A lot, according to a new study that is the first to identify that a conserved gene — translin — works as a modulator of sleep in response to metabolic changes.

People with type 2 diabetes and obstructive sleep apnea (OSA) may not experience improved glycemic control by using continuous positive airway pressure, or CPAP, as some studies have suggested, according to the results of a randomized, controlled trial published online ahead of print in the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine.

Brain Activity of Nematodes Seeking Food Offers New View on Sleep

If you have trouble sleeping, the neurons in your brain may be firing like those in roundworms randomly seeking food in the absence of clues, says University of Oregon biologist Shawn R. Lockery.

Inspire to Sleep Easier

Until recently, there was little relief for sleep apnea patients who can’t tolerate treatment with devices that deliver continuous positive airway pressure, or CPAP for short. “Many remove the device during sleep without knowing it, or give up and have been told there aren’t any other options,” Losavio says. Now he is offering a new treatment, called upper airway stimulation therapy or Inspire therapy, to help those with moderate to severe obstructive sleep apnea who are unable to use CPAP. The FDA approved Inspire therapy in 2014.

Molecule Induces Lifesaving Sleep in Worms

Sometimes, a nematode worm just needs to take a nap. In fact, its life may depend on it. New research has identified a protein that promotes a sleep-like state in the nematode Caenorhabditis elegans. Without the snooze-inducing molecule, worms are more likely to die when confronted with stressful conditions, report researchers in the March 7, 2016 issue of the journal GENETICS.
