Frailty or frailty syndrome refers to a state of health in which older adults gradually lose their bodies' in-built reserves and functioning. This makes them more vulnerable, less able to recover and even apparently minor events (infections, environmental changes) can have drastic impacts on their physical and mental health.
Silencing of the FMR1 gene in Fragile X syndrome. FMR1 co-localizes with a rare fragile site, visible here as a gap on the long arms of the X chromosome.. A chromosomal fragile site is a specific heritable point on a chromosome that tends to form a gap or constriction and may tend to break [1] when the cell is exposed to partial replication stress. [2]
Likewise fragility is defined as a concave sensitivity to stressors, leading to a negative sensitivity to increase in volatility. The relation between fragility, convexity, and sensitivity to disorder is mathematical, obtained by theorem, not derived from empirical data mining or some historical narrative. It is a priori.
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Fragility may refer to: A property of a solid, related to brittleness; Fragility (glass physics), a concept to characterize viscous slow down during glass formation;
The increase in the surface area to volume ratio also gives the cell decreased osmotic fragility, as it allows it to take up more water for a given amount of osmotic stress. In vivo (within the blood vessel), the codocyte is a bell-shaped cell. It assumes a "target" configuration only when processed to obtain a blood film.
Likewise, fragility is defined as a concave sensitivity to stressors, leading to a negative sensitivity to an increase in volatility. [ 1 ] Taleb's thesis is that in a volatile world with a lot of destructive uncertainty, the wise economic strategy is to be antifragile: protect the downside but prepare to benefit disproportionately from ...
Osmotic fragility (OF) refers to the degree or proportion of hemolysis that occurs when a sample of red blood cells are subjected to osmotic stress by being placed in a hypotonic solution. Osmotic fragility is affected by various factors, including membrane composition and integrity as well as the cells' sizes or surface-area-to-volume ratios.
