This accumulation of deleterious mutations without the chance to reduce them again in organisms without meiotic recombination has been termed Muller's ratchet [ 70, 71], and has been shown to lead to an increased extinction risk in asexual organisms [ 72].
Since plants are immobile, they face a myriad of possible deleterious stimuli without any possibility to depart.
They also estimated that infusions greater than 0.04 U/min were accompanied by deleterious effects, without any gain in efficacy.
Natural antioxidant defenses may be overwhelmed and thus allow the oxygen radicals to exert their deleterious effects without control.
We conclude that the proposed popLowess strategy is robust in the sense that it can handle the presence of otherwise deleterious populations without relying on them.
Patients with non-infective febrile responses may experience these deleterious effects without the potential benefit of fever-related protection against viruses or bacteria or both.
The leading question is what, if anything, can we do to prevent these deleterious changes without dangerously dysregulating the precarious balance of productive immunity versus immunopathology?
In addition, intraindividual selection, probably due to atresia and the MC, purges nonsynonymous deleterious mutations without evolutionary cost for the individual.
Because populations evolution is according to Muller's ratchet, that is in the presence of deleterious mutation, without any recombination, but with selection and random drift.
Considering the Yin and Yang effects of innate immune system, an overall suppression or activation of innate immunity might not be beneficial, while the true challenge is to selectively inhibit the deleterious effects without compromising the beneficial roles of innate immune response in tissue repair, remodeling, and recovery.
