The only other known difference between the cohorts is that many of patients in the usual care cohort resided further from Seattle that those recruited to the ANC cohort.
When a genotype resides at the multivariate optimum, any new mutation will move phenotypes away from the optimum and, therefore, will be deleterious; but if a genotype resides further from the optimum, a greater proportion of mutations will entail phenotypic changes that bring the resulting genotype closer to the optimum and, thus, are beneficial for fitness.
Thus, residing further away from endosteum, by increasing oxidative damage to DNA, could increase the mutational load in HSC.
"We also calculated higher cancer risks for residents living nearer to the wells as compared to those residing further [away]," the report said.
Distance of households from the water distribution centers was identified as an important factor affecting compliance to the intervention: non-compliant families tended to reside further away from the water distribution centers than compliant families.
Participants that resided further than 1 km from the park were less likely to use walking paths (OR = 0.703, 95% CI 0.530 0.933).
These travel costs are subsidised by the health system through the Patient Travel Scheme (PTS) for patients who reside further than 50 km from the hospital; at the time of the study, families were reimbursed $0.15/km travelled by road, and the full cost of air transport [ 19].
He added: "Before, towns clung close to the train, but now the car allowed people to reside further afield.
In vivo, multiphoton intravital microscopic analysis of HSC in the bone marrow of young and old mice has revealed that old HSC reside further away from the endosteum than young HSC progenitors, indicating age-related extrinsic changes in niche composition that could impact HSC function [ 30].
It has been further argued, from Australian studies that, "Children and youth residing away from their parents in court-ordered care represent one of the most vulnerable and disadvantaged groups in Western society.
