Newborns with higher hair cortisol levels take longer to fall asleep

Results suggest that cortisol levels in late pregnancy can predict infant sleep at 7 months of age

2023-05-30
(Press-News.org) DARIEN, IL – Cortisol levels in late pregnancy can predict the sleep of infants, according to a new study to be presented at the SLEEP 2023 annual meeting. 

Results show that newborns with higher levels of cortisol in their hair samples took longer to fall asleep at 7 months of age. Neonatal hair cortisol is a measure of fetal cortisol in the last trimester of pregnancy. 

“Although increases in cortisol across pregnancy are normal and important for preparing the fetus for birth, our findings suggest that higher cortisol levels during late pregnancy could predict the infant having trouble falling asleep,” said lead co-author Melissa Nevarez-Brewster, graduate student at the University of Denver. “We are excited to conduct future studies to better understand this link.” 

The researchers collected hair cortisol from 70 infants in the first days after birth; 57% of the infants were female. Parents then completed a sleep questionnaire when their child was 7 months old. Analyses covaried for gestational age at birth and family income-to-needs ratio. 

Tessa Benefield, lead co-author and research staff, noted that it will be important for future research to further study potential long-term effects of fetal cortisol production on sleep health through infancy into childhood. 

“The results indicate that there may be prenatal influences on sleep health early in life, pointing to the need to better understand what factors may set the stage for better sleep health in infancy and beyond,” she said. 

This study was supported by funding from the National Institutes of Health. The research abstract was published recently in an online supplement of the journal Sleep and will be presented Tuesday, June 6, during SLEEP 2023 in Indianapolis. SLEEP is the annual meeting of the Associated Professional Sleep Societies, a joint venture of the American Academy of Sleep Medicine and the Sleep Research Society.

Using AI to create better, more potent medicines

2023-05-30
COLUMBUS, Ohio – While it can take years for the pharmaceutical industry to create medicines capable of treating or curing human disease, a new study suggests that using generative artificial intelligence could vastly accelerate the drug-development process.  Today, most drug discovery is carried out by human chemists who rely on their knowledge and experience to select and synthesize the right molecules needed to become the safe and efficient medicines we depend on. To identify the synthesis paths, scientists often employ a technique called retrosynthesis – a method for creating potential drugs by working backward from the wanted molecules and searching for chemical reactions ...

May 30, 2023, Mountain View, CA – Akshay Suresh, a graduate student at Cornell University, spearheads an extraordinary scientific endeavor -- a groundbreaking mission to uncover periodic signals emanating from the core of the Milky Way called the Breakthrough Listen Investigation for Periodic Spectral Signals (BLIPSS). Such repetitive patterns could be the key to unlocking the mysteries of extraterrestrial intelligence in our galaxy. Suresh and his co-authors detail the project’s results thus far in a paper accepted for publication in the Astronomical Journal, “A 4–8 GHz Galactic Center Search for Periodic Technosignatures.” BLIPSS ...

“In this study, we present novel transcriptional dependencies between MALAT1 and MAPK-pathway-associated genes in melanoma.” BUFFALO, NY- May 30, 2023 – A new research paper was published in Oncotarget's Volume 14 on May 26, 2023, entitled, “Deconstructing the role of MALAT1 in MAPK-signaling in melanoma: insights from antisense oligonucleotide treatment.” The long non-coding RNA (lncRNA) MALAT1 is a regulator of oncogenesis and cancer progression. MAPK-pathway upregulation is the main event in the development and progression of human cancer, including melanoma and recent studies have shown that MALAT1 has a significant impact on the ...

Obstructive sleep apnea disrupts gene activity throughout the day in mice

Obstructive sleep apnea disrupts gene activity throughout the day in mice
2023-05-30
The low blood oxygen levels of obstructive sleep apnea cause widespread changes in gene activity throughout the day, according to a new study in the open-access journal PLOS Biology by David Smith of Cincinnati Children’s Hospital Medical Center, US, and colleagues. The finding may lead to tools for earlier diagnosis and tracking of the disorder. Obstructive sleep apnea (OSA) occurs when the airway becomes blocked (usually by soft tissue, associated with snoring and interrupted breathing during the night), resulting in intermittent hypoxia (low blood oxygen) and disrupted sleep. ...

Researchers use ‘natural’ system to identify proteins most useful for developing an effective HIV vaccine
2023-05-30
Since it was identified in 1984 as the cause of Acquired Immune Deficiency Syndrome (AIDS), the human immunodeficiency virus (HIV) has infected more than 80 million people and been responsible for some 40 million deaths worldwide, according to the World Health Organization (WHO). Currently, the WHO reports more than 38 million people globally live with the retrovirus, and each year, another 1 million new cases are diagnosed. While antiretroviral therapy helps keep HIV in check, patients must stay on their medication to prevent the development of AIDS. Scientists have spent years trying to develop an ...

Illinois professor examines lasting legacy of al-Andalus for Arabs, Muslims today

Illinois professor examines lasting legacy of al-Andalus for Arabs, Muslims today
2023-05-30
CHAMPAIGN, Ill. — Before it was home to Spain and Portugal, much of the Iberian Peninsula was ruled by a succession of Islamic dynasties for almost 800 years during the Middle Ages. Known as al-Andalus, its influence is still reflected in art and politics today – not only in Spain and North Africa, but also in places far from the historical site of al-Andalus. Eric Calderwood, a comparative and world literature professor at the University of Illinois Urbana-Champaign, wrote about that influence and how it is used to make sense of the present in his new book, “On Earth or in Poems: ...

Astronomers discover planets in NASA Kepler's final days of observations

Astronomers discover planets in NASA Keplers final days of observations
2023-05-30
A team of astrophysicists and citizen scientists have identified what may be some of the last planets NASA’s retired Kepler space telescope observed during its nearly decade-long mission. The trio of exoplanets – worlds beyond our solar system – are all between the size of Earth and Neptune and closely orbit their stars. ''These are fairly average planets in the grand scheme of Kepler observations,” said Elyse Incha, a senior at the University of Wisconsin-Madison. “But they’re exciting because Kepler observed them during its last few days of operations. It showcases just how good Kepler was at planet hunting, even at the end of its ...
