Sleep Problems: May Be Linked To Gene Mutation

Up to 80 % of children with autism spectrum disorder (ASD) experience sleep problems. The source of these problems has been as much of a mystery as the exact causes of ASD; which scientists are still working to unravel. A new study led by a team of neuroscientists at Washington State University has brought scientists…

Melatonin Receptors

Two Melatonin Receptors Vital For Sleep

An international team of researchers used an X-ray laser at the Department of Energy’s SLAC National Accelerator Laboratory to create the first detailed; maps of two melatonin receptors that tell our bodies when to go to sleep or wake up and guide other biological processes. A better understanding of how they work could enable researchers…

Trouble Sleeping

Stressed At Work And Trouble Sleeping?

Work stress and impaired sleep are linked to a threefold higher risk of cardiovascular death in employees with hypertension. That’s the finding of research published in the European Journal of Preventive Cardiology; a journal of the European Society of Cardiology (ESC). So One-third of the working population has hypertension (high blood pressure). But Previous research…

Stem cell

Biomaterial Scaffolds With Stem Cells For Tissue Engineering

The publication of its inaugural article, “Combining Stem Cells and Biomaterial Scaffolds for Constructing Tissues and Cell Delivery. This timely overview of the available biomaterials for directing stem cell differentiation as a means of producing replacements for diseased or damaged tissues is a comprehensive update of the classic review published in StemBook in 2008. The biomaterials have…

Sleep Loss

Sleep Loss Interferes With Job Performance

Sleep deprivation, also as insufficient sleep, is the condition of not having enough sleep. It can either chronic or acute and may vary widely in severity. A chronic sleep-restricted state can cause fatigue, daytime sleepiness, clumsiness, and weight gain. It adversely affects the brain and cognitive function. However, in a subset of cases sleep deprivation can, paradoxically, lead to increased energy and alertness…

Snoring during sleep

Prevalence And Intensity Of Their Own Snoring

Snoring is the vibration of respiratory structures and the resulting sound due to obstructed air movement during breathing while sleeping. In some cases, the sound may be soft; but in most cases, it can be loud and unpleasant. Snoring during sleep may be a sign, or first alarm, of obstructive sleep apnea (OSA). Research suggests that snoring is…

Sleep Routine

Shorting Your Sleep Routine During The Work-Week

Losing just 16 minutes of sleep could be the difference between a clear-headed day at the office or one filled with distractions. A new study published in the Sleep Health (Journal of the National Sleep Foundation) finds shorting your sleep routine during the work-week greatly interferes with job performance. University of South Florida researchers found workers are…

Stem Cells

First Cancer Treatment Made From Stem Cells

A new form of cancer immunotherapy has given to a University of California, San Diego Health patient in the first test of immune cells grown from stem cells. The patient, Derek Ruff, is being treated for stage four colon cancer; which recurred after a decade in remission. The disease continued to progress despite chemotherapy and…

Sleep apnea

Developing Oral Appliance To Help Sufferers Of Sleep

Researchers measured a novel treatment for sleep apnea developed at Hiroshima University Hospital with positive results. By measuring patients lying down flat, the researchers stimulated sleep conditions and measured the patient’s airways using 3D imaging. The study confirmed that the treatment is effective at opening the airways and warrants further collaboration; between dentists and doctors…

Sleep Myths

Common Sleep Myths Compromise Good Sleep

People often say they can get by on five or fewer hours of sleep; that snoring is harmless, and that having a drink helps you to fall asleep.  These are, in fact, among the most widely held myths about sleeping that not only shape poor habits, but may also pose a significant public health threat, according to a…

Obstructive sleep apnea

Obstructive Sleep Apnea Is An Important Public Health Problem

Researchers report the use of the CPAP mask may greatly increase their chances for a longer life. Use of the continuous positive airway pressure (CPAP); masks to a 62% decline in the odds for death over 11 years of follow-up. That benefit held even after factoring in health risk factors such as heart disease, weight,…

Mitochondria

Mitochondria Is Important For The Health Of Dopaminergic Neurons

The mitochondrion (plural mitochondria) is a double-membrane-bound organelle found in most eukaryotic organisms. Some cells in some multicellular organisms may, however, lack them. A number of unicellular organisms, such as microsporidia, parabasalids, and diplomonads; have also reduced or transformed their mitochondria into other structures. To date, only one eukaryote, Monocercomonoides, is known to have completely lost its…
