Your Brain May Actively Forget During REM Sleep
Rapid eye movement, or REM, sleep is when most of our dreams are made. Now, in a study of mice, a team of Japanese and U.S. researchers show that it may also be a time when the brain actively forgets.
Senescent Cell Burden is Reduced in Humans by Senolytic Drugs
In a small safety and feasibility clinical trial, Mayo Clinic researchers have demonstrated for the first time that senescent cells can be removed from the body using drugs termed “senolytics”. The result was verified not only in analysis of blood but also in changes in skin and fat tissue senescent cell abundance. The findings appear in the journal EBioMedicine.
Lithium, Trametinib and Rapamycin Combo Extends Lifespan of Fruit Flies by 48%
A triple drug combination has been used to extend the lifespan of fruit flies by 48% in a new study led by UCL and the Max Planck Institute for Biology of Ageing. The three drugs are all already in use as medical treatments: lithium as a mood stabiliser, trametinib as a cancer treatment and rapamycin as an immune system regulator.
The Scientific Evidence for the Health Benefits of Cordyceps
The Cordyceps fungus is said to have the power to fix a host of health problems, from muscle fatigue to diabetes. But are the claims too good to be true?
'Tantalizing' Results For A Test Of Vitamin C For Sepsis
Could the leading cause of death in hospitals be curtailed with a safe and inexpensive treatment that includes vitamin C? That question has been on the minds of intensive care doctors since the spring of 2017, when a well-known physician asserted that he was saving the lives of most of his patients with sepsis by using a treatment based on intravenous vitamin C.
Reduced Slow-Wave Sleep Is Associated with High Cerebrospinal Fluid Aβ42 Levels
Emerging evidence suggests a role for sleep in contributing to the progression of Alzheimer disease (AD). Slow wave sleep (SWS) is the stage during which synaptic activity is minimal and clearance of neuronal metabolites is high, making it an ideal state to regulate levels of amyloid beta (Aβ).
What About Sleep Changes with Age?
Older adults do not sleep as well as younger adults. Why? What alterations in sleep quantity and quality occur as we age, and are there functional consequences? What are the underlying neural mechanisms that explain age-related sleep disruption? This review tackles these questions.
Xylaria Nigripes Mitigates Spatial Memory Impairment Induced by REM Sleep Deprivation
Xylaria Nigripes exerts effective protection against spatial memory impairment induced by rapid eye movement sleep deprivation in rats; Xylaria Nigripes is a potential effective drug to treat spatial memory impairment. Its act mechanism could be elevating phosphorylation of CREB in hippocampus.
The Heterogeneity of Senescent Cells
Cellular senescence, discovered in 1961 by Leonard Hayflick and Paul Moorhead, is a state in which cells no longer perform their functions, instead emitting harmful chemicals that turn other cells senescent. Senescence is primarily caused by telomere shortening and DNA damage, and senescent cells are known to contribute to multiple diseases, such as Alzheimer’s, Parkinson’s, and dementia.
Sleeping Less Than 6 Hours with Heart Disease and Diabetes is a Deadly Combo
Middle-aged adults with high blood pressure, Type 2 diabetes, heart disease or stroke could be at increased risk for cancer and early death when sleeping less than 6 hours per day.
