Scientists suspect that routine exposure to varicella--through contact with people with chicken pox--boosts the immune system and keeps the virus at bay.
In addition, photosynthetic endosymbionts typically release more oxygen than the symbiosis is able to consume in respiration, so that animal tissues are hyperoxic when illuminated, with pO2 often exceeding 250% air saturation during routine exposure to normal daytime irradiances [2].
Older GPs, women (whose routine exposure to prostate cancer is likely to be infrequent), those with less education and research exposure seemed to be more likely to perhaps trust their clinical experience, however limited.
Each has intimate contact with an aqueous environment that is constant parametric change and within which there can be routine exposure to potential pathogens ranging from microscale (bacteria and viruses) to macroscale (parasites).
Routine exposures to certain environmental contaminants, especially those with the ability to alter endocrine signaling, are currently being scrutinized for their potential roles in breast cancer causation.
This scenario represents high but routine exposures to lead in tap water, because the longer corrosive water sits in contact with lead parts, the more lead leaches out.
A small nested case control study of 11 cases observed that routine potential exposure to epichlorohydrin was associated with CNS tumours, but with a large CI (odds ratio=4.2, 95% CI=0.7 26.0) (Barbone et al, 1994).
This agrees with its vasoconstrictor effect on isolated pulmonary artery, where it was measured after routine priming with repeated exposure to KCl (24).
Regular routines, minimal exposure to electronic media and avoidance of caffeine at bedtime, as well as exercise are well-known practices consistent with good sleep hygiene [ 32].
Inferences regarding determinants of routine immunization coverage are therefore based solely upon statistical association of routine immunization performance indicators with exposure to IEC materials and other respondent factors.
