Antioxidants are extremely important for your overall health. They are linked to protection from a variety of chronic diseases. An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction that can produce free radicals, leading to chain reactions that may damage cells.
Researchers in the field have developed approaches to produce living organs that are constructed with the appropriate biological and mechanical properties.
Linear regression was the first type of regression analysis to be studied rigorously, and to be used extensively in practical applications.
Silicon nitride is a chemical compound of the elements silicon and nitrogen, with the formula Si3N4. Silicon nitride has many orthopedic applications. The material is also an alternative to PEEK (polyether ether ketone) and titanium, which are used for spinal fusion devices.
Growth differentiation factor 11 (GDF11) also known as bone morphogenetic protein 11 (BMP-11) is a protein that in humans is encoded by the GDF11 gene.
Growth hormone (GH) is a small protein that is made by the pituitary gland and secreted into the bloodstream. GH production is controlled by a complex set of hormones produced in the hypothalamus of the brain and in the intestinal tract and pancreas.
Biomarkers of aging are biomarkers that better predict functional capacity at a later age. Validated biomarkers of aging would allow for testing interventions to extend lifespan, because changes in the biomarkers would be observable throughout the lifespan of the organism.
Tissues are maintained through a balance of cellular aging and regeneration. Aging refers to the gradual loss of cellular function, and regeneration is the repair of damaged tissue generally mediated by preexisting adult or somatic stem cells. Scientists are interested in understanding the biological mechanisms behind these two complex processes.
Gene expression changes could serve as biomarkers of physiological decline and play important roles in anti-aging.
DNA is continuously subject to damage due to a variety of endogenous and exogenous factors.
The skin anti-aging strategies attempted to reverse the dermal and epidermal signs.
Studies have consistently revealed FOXO (Forkhead box O) transcription factors as important determinants in aging and longevity.
H3K4me3 denotes a specific chemical modification of proteins used to package DNA in eukaryotic cells (including human cells). The proteins, known as histones, are major components of chromosomes. This modification is commonly associated with active transcription of nearby genes.
KU-60019, an inhibitor of ATM protein, which is a phosphorylation enzyme, recovers the functions of aging cells through activation of lysosomal functions and induction of cell proliferation.
