First look at pupil size in sleeping mice yields surprises
When people are awake, their pupils regularly change in size. Those changes are meaningful, reflecting shifting attention or vigilance, for example. Now, researchers reporting in Current Biology on January 18 have found in studies of mice that pupil size also fluctuates during sleep. They also show that pupil size is a reliable indicator of sleep states. We found that pupil size rhythmically fluctuates during sleep, says Daniel Huber of the University of G ...

These carbon dioxide-sensing neurons wake up mice
Stimulating a population of neurons in the midbrain with carbon dioxide CO2 awakens adult male mice without enhancing breathing, finds a study published in JNeurosci . These findings are relevant to understanding disorders such as obstructive sleep apnea, sudden infant death syndrome and sudden unexpected death in epilepsy. Rising levels of CO2 trigger the drive to breathe, and cause arousal from sleep. Disorders that interfere with this important signal c ...

Pulling an all-nighter impairs working memory in women
Over the last few decades, a wealth of evidence has accumulated to suggest that a lack of sleep is bad for mind and body. Working memory is important for keeping things in mind for briefer periods of time, which thereby facilitates reasoning and planning. A team of sleep scientists from Uppsala University now demonstrates that acute sleep loss impacts working memory differently in women and men. In the current study from the Department of Neuroscience at U ...

Star-like cells may help the brain tune breathing rhythms
Traditionally, scientists thought that star-shaped brain cells called astrocytes were steady, quiet supporters of their talkative, wire-like neighbors, called neurons. Now, an NIH study suggests that astrocytes may also have their say. It showed that silencing astrocytes in the brain s breathing center caused rats to breathe at a lower rate and tire out on a treadmill earlier than normal. These were just two examples of changes in breathing caused by manip ...

Tests on airway tissue reveal glo vapour has minimal impact compared to smoke
Scientists at British American Tobacco observed changes in just two genes when human airway tissue was exposed to vapour from its tobacco heating product THP - glo. This compares to thousands of gene changes observed in tissue exposed to cigarette smoke. The impact on tissue exposed to glo vapour was minimal and more comparable with that of air when tested in laboratory conditions Figure 1 . These results add to evidence suggesting that glo has the potenti ...

Study of first-graders shows fetal alcohol spectrum disorders prevalent in US ...
A study of more than 6,000 first-graders across four U.S. communities has found that a significant number of the children have fetal alcohol spectrum disorders FASD , with conservative rates ranging from 1 to 5 percent in community samples. The new findings represent more accurate prevalence estimates of FASD among general U.S. communities than prior research. Previous FASD estimates were based on smaller study populations and did not reflect the overall U ...

Children affected by prenatal drinking more numerous than previously estimated
Researchers at University of California San Diego School of Medicine found a significant number of children across four regions in the United States were determined to have fetal alcohol spectrum disorders FASD . The new findings may represent more accurate prevalence estimates of FASD among the general population than prior research. The study is published online in the Journal of the American Medical Association . More than 6,000 first-graders in the Pac ...

CORVALLIS, Ore. - Symptoms of alcoholism make it more difficult for some people to regularly take the prescription drug naltrexone, which could help treat their disease, a researcher at Oregon State University has found. The finding helps researchers better understand how to intervene with patients to improve the effectiveness of the medication, said Sarah Dermody, an assistant professor in the School of Psychological Science in OSU s College of Liberal Ar ...

Study questions link between medical marijuana and fewer opioid deaths
The association between medical marijuana and lower levels of opioid overdose deaths -- identified previously in several studies -- is more complex than previously described and appears to be changing as both medical marijuana laws and the opioid crisis evolve, according to a new RAND Corporation study. The report -- the most-detailed examination of medical marijuana and opioid deaths conducted to date -- found that legalizing medical marijuana was associa ...

Geography matters: Prescribing patterns for opioids in dermatology
A new study suggests that opioid prescribing is not widespread among dermatologists, but opportunities exist in concentrated areas to reduce their use. The study appears online Feb. 7 in JAMA Dermatology . A small number of dermatologists account for a large percentage of the prescriptions. And it s concentrated among dermatology surgeons, who are likely giving a standard prescription for a four-day course of opioids after surgery, said Arash Mostaghimi, M ...

Sexual minority young people are at a higher risk for suicide
Lesbian, gay, bisexual or questioning LGBQ young people are at substantially higher risk of suicidal behavior than their heterosexual peers, according to a new study published in JAMA Journal of the American Medical Association. As part of the most recent National Youth Risk Behavior Survey -- the largest national survey on adolescent health -- 15,624 high school students were asked whether in the past year they had seriously considered suicide, planned su ...
