Sleep is a physiological behavior that is common in all animal species. It forms around one third of a human life. It is not known clearly the exact functions of sleep but it seems to be essential for survival as prolonged sleep deprivation leads to severe physical impairment followed by cognitive loss and eventually death.
Almost all cells regulate their biological processes over a 24-hour period, otherwise called a cell's circadian rhythm. To do so, cells use a biological clock that cycles different genes on and off throughout the day and night.
Recent research demonstrates how circadian rhythms in heart cells help to change heart function.
Almost every living thing on Earth-;from bacteria to plants to people-;have a circadian rhythm, the biological clock that controls both physiology and behavior of organisms over a 24-hour period.
A group of scientists combined their mastery to obtain a thorough understanding of the risks linked with cannabis exposure at the time of pregnancy.
Only 21 percent of patients with severe pneumonia caused by SARS-CoV-2 (the virus that causes COVID-19) have a documented bacterial superinfection at the time of intubation, resulting in potential overuse of antibiotics, according to new research published online in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.
A gene called Npas4, already known to play a key role in balancing excitatory and inhibitory inputs in brain cells, appears to also be a master timekeeper for the brain's circadian clock, new research led by UT Southwestern scientists suggests.
Time-restricted eating (TRE) is a dietary regimen in which eating is restricted to particular hours. It has received great attention in weight-loss circles.
A new study has demonstrated the removal of damaged mitochondria from the brain cells of mice treated with a small molecule compound for Parkinson’s disease.
A new study published in Nature Communications suggests that gene therapy delivered into the brain may be safe and effective in treating aromatic L-amino acid decarboxylase (AADC) deficiency.
Children with a devastating genetic disorder characterized by severe motor disability and developmental delay have experienced sometimes dramatic improvements in a gene therapy trial launched at UCSF Benioff Children's Hospitals.
In this interview, News-Medical speaks to Dr. James Shikany about diet and how different diets can affect your risk for cardiac death.
In a paper published by the Journal of Sleep Research, researchers reveal how they examined data* from half a million middle-aged UK participants asked if they had trouble falling asleep at night or woke up in the middle of the night.
According to a recent study, people who self-report daytime sleepiness have shorter telomeres irrespective of whether they have obstructive sleep apnea.
A new analysis of the entire genetic makeup of more than 53,000 people offers a bonanza of valuable insights into heart, lung, blood and sleep disorders, paving the way for new and better ways to treat and prevent some of the most common causes of disability and death.
Researchers from the University of Minnesota Twin Cities College of Science and Engineering and Medical School have developed a unique head-mounted mini-microscope device that allows them to image complex brain functions of freely moving mice in real time over a period of more than 300 days.
In a new study published in JAMA Pediatrics, researchers at Children's Hospital Colorado have found that tetrahydrocannabinol (THC), the psychoactive component of marijuana, stays in breast milk for up to six weeks, further supporting the recommendations of the American Academy of Pediatrics, the American College of Obstetricians and Gynecologists and the Academy of Breastfeeding Medicine to abstain from marijuana use during pregnancy and while a mother is breastfeeding.
A new study has demonstrated how plants exploit their metabolism to identify time and know when to develop.
According to a recent study, sufficient rest during vacation time restored functions linked to DNA regulation in shift workers deprived of sleep.
Coffee, cola, or an energy drink: caffeine is the world's most widely consumed psychoactive substance. Researchers from the University of Basel have now shown in a study that regular caffeine intake can change the gray matter of the brain. However, the effect appears to be temporary.
A tiny population of neurons known to be important to appetite appear to also have a significant role in depression that results from unpredictable, chronic stress, scientists say.
