In vitro fertilization
Researchers publishing in Aging have found that rapamycin, a molecule thoroughly researched for its effects on metabolism, improves the viability of egg cells (oocytes) grown in vitro. Another approach towards a known problem Decreased fertility in women occurs much more rapidly than other aspects of aging, and advanced maternal age has a substantial impact on...
Walking Seniors
In a new study published in International Journal of Environmental Research and Public Health, Japanese researchers have shown that astaxanthin supplementation improves endurance in healthy older adults [1]. Muscles succumb to oxidative stress Aging leads to reduced muscle strength and endurance. Currently, exercising is the only method to slow down these processes, but it is...
Microplastics
A paper published in Environmental Science and Technology has described some of the effects of nanoplastics on human liver and lung cells [1]. Microplastics and nanoplastics Plastics in the environment are gradually broken down by sunlight, grinding processes, and biological activities into smaller and smaller pieces [2]. These are the infamous microplastics, but when they...
Dividing cell
Researchers publishing in Cell Stem Cell have found that the mitochondrial protein OPA1 is an integral, regulatory part of muscle stem cell activation, the process by which muscle stem cells proliferate and become active muscle tissue (myogenesis) [1]. Another piece of the puzzle We have recently reported on the effects of mitochondrial fusion and fission...
Atherosclerosis
Scientists have drastically improved various symptoms of atherosclerosis in mice by precisely targeting mitochondria with a plant-derived antioxidant [1]. Age-related and deadly Atherosclerosis, the accumulation of plaques on arterial walls, is one of the deadliest age-related diseases. Atherosclerotic plaques, which consist mostly of cholesterol and fat, can impede blood flow in the artery or burst,...
Early embryo
Scientists have discovered that immature oocytes maintain their youth by shutting down one of the protein complexes that produce energy in mitochondria [1]. Live slow, stay young Every female is endowed with a finite number of oocytes that form before birth, then reside in the ovaries in a dormant state until maturation and release. Oocytes...
