Genetic effects include reduced effective population size, increased population substructure, and decreased adaptive potential.
In the human hematopoietic system, aging is concomitant with decreased bone marrow cellularity and decreased adaptive immune system function.
Loss of genetic diversity may increase the risk of extinction due to decreased reproductive fitness, decreased adaptive flexibility, and increased disease susceptibility [ 3].
The loss of genetic diversity may increase the risk of extinction due to decreased reproductive fitness, decreased adaptive flexibility, and increased disease susceptibility [ 17].
That is, a long duration of unemployment may provoke appraisals that job loss is irreversible, which may promote maladaptive coping and decrease adaptive coping in unemployed individuals.
We designed a single-center prospective, observational study to test the hypothesis that children with septic shock would have decreased adaptive immune function compared with healthy children and that among children with sepsis, lower adaptive immune function would be associated with the development of persistent infection or new nosocomial infection.
We have reviewed the various changes within the hematopoietic system with aging that are expected to contribute to increased cancer incidence in the elderly, including accumulating mutations and epigenetic changes, increased inflammation, decreased adaptive immunity, altered numbers and fitness of progenitors, and other alterations that could change the adaptive landscape.
The increasing proportion of elderly people and the associated health problems among the elderly were understood as factors decreasing the adaptive capacity in a community.
This is a necessary safety measure, because if the lower threshold remains unbound, then an attacker could decrease the adaptive threshold indefinitely and artificially induce very low specificity (almost all traffic would be classified as attack).
