The multistep process of radiation carcinogenesis begins in histologically normal thyroid tissue and may involve dose-dependent gene expression changes.
The West should do all it can to safeguard that openness — and that may involve an occasional dose of "secular fascism".
These procedures may involve high radiation dose rates in the interventional laboratory [ 10, 11].
Such studies may involve mirroring clinical dose schedules (30 35 fractions over 6 7 weeks) and, as a result, they are both labour intensive and expensive.
More aggressive initial therapy may involve adding low-dose steroids, using combination DMARDs and the early use of biologics.
While treatment of malignancies may involve administration of high dose (≥500 mg/m) to low dose (<50 mg/m) MTX over a short time period, treatment of autoimmune diseases usually involves low doses of MTX over long periods of time.
This may involve exploration of alternative doses, e.g., to illustrate that a lower dose would provide insufficient effects and that higher doses would be associated with limited additional benefit or unacceptable tolerability.
However, depending on the operating parameters and scan length, this may involve considerable ionising radiation dose per scan (0.02 0.6 Gy; typically 0.1 0.3 Gy) (Boone et al, 2004; Carlson et al, 2007; Brindle, 2008).
On the other hand, because Nec-1 and Nec-1i, but not Nec-1s, were able to block IDO in vitro, we speculate that the sensitizing effect of Nec-1 and Nec-1i, but not Nec-1s, at lower dose in vivo may involve IDO targeting, although further research is required to support this hypothesis.
19, 41 High doses of UVA1 may involve heat, making their use intolerable, which led to the development of cold-light UVA1 lamps that include a cooling system for filtering the infrared radiation.
It might be that improved sustained attention is due to improved noradrenergic functioning following low doses and that the higher doses reducing overactivity and impulsiveness may involve other neuromodulators like dopamine in addition to norepinephrine.
