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.
It happens in the first hours after fertilization: The cells of the early embryo begin to independently produce proteins, the building blocks for cells and organs.
According to research, the brain’s capacity to clear a protein closely associated with Alzheimer’s disease is tied to the circadian cycle.
The link between nutrition and mating is not limited to humans; it can be found in animals from all over the world.
Gestation leads to a modification of brain circuits and behaviors such as nesting within the animal kingdom. The underlying biological, neural and hormonal mechanisms have been unknown until now.
Researchers at Baylor College of Medicine, Yale University and other institutions have identified previously unrecognized changes in gene expression and cellular interactions in distinct cell populations in chronic obstructive pulmonary disease (COPD).
LMU neuroscientists have shown that breathing coordinates neuronal activity throughout the brain during sleep and quiet.
Scientists from Tokyo Metropolitan University recently gained a deeper understanding of the biochemistry of long-term memory.
What are the effects of eating during the nighttime instead of the daytime? New research, focused on a simulation of night shift work, may hold implications for people eating at atypical times -; like those experiencing jet lag, circadian rhythm sleep disorders, or who tend to sleep late during the weekends.
Analyzing molecular characteristics and their variation during lifestyle changes, by combining digital tools, classical laboratory tests and new biomolecular measurements, could enable individualised prevention of disease.
New research from RCSI has demonstrated the significant role that an irregular body clock plays in driving inflammation in the body's immune cells, with implications for the most serious and prevalent diseases in humans.
Life is organized on a 24-hour schedule. Central to this regular rhythm is the circadian clock, timekeepers that are present in virtually every organ, tissue and cell type.
Researchers have long known that air pollution can increase the risk of disorders such as obesity, diabetes, and fertility, but they did not know the exact mechanism for how it can lead to these health conditions.
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.
