Ionizing radiation is a known human carcinogen that can induce a variety of biological effects depending on the physical nature, duration, doses and dose-rates of exposure.
It is seen that for a given pair of repressor and operator there are multiple ways to alter the nature of dose response.
The activity of the downstream target of p38, USF-1, is modulated through post-translational modification, again depending on the nature and dose of UV exposure, either promoting gene expression or inducing a transcriptional block [17], [18].
Nonclinical studies are typically short term (days to months) in nature where dose formulations are in early development stages and samples are limited.
The extent of renal damage depends on the nature, the dose, route, and duration of exposition displaying diverse degree of severity ranging from mild tubular dysfunction to severe renal failure.
All women meeting predetermined criteria were offered dietary advice and other treatment, but response to treatment offered, the nature and dose of such treatments, and adherence to any advice or treatments received are unclear.
The observed large variances may result from an insufficient number of underlying articles describing dose-response or from the non-linear nature of dose-response relationships.
Workability is improved by increasing Water/Cement ratio; it also relies on fine nature and dosing when W/C ratio is fixed.
However, despite promising therapeutic results in 59 75% of cases, the reported studies share common drawbacks, i.e. the absence of a control group, their retrospective nature, variable dosing and duration of therapy, simultaneous administration of other antibiotics in >70% and a lack of resistance development monitoring.
And they've never been observed in history or in nature at doses below 10 rem (0.1 Sv).
