The DEP effect is particularly clear at the higher DEP exposure dose. These results show that AMs respond to Listeria infection with increased secretion of IL-1[beta], TNF-[alpha], and IL-12.
The toxicity of HDI to A549 and NCI-H292 cells was comparable over this broad exposure dose range.
Compound NHEL NOAEL 4-MBC NHEL = 66 mg/kg/day (1) NOAEL (subchronic oral rat study) = 25 mg/kg/day (10) SED = 0.23 mg/kg (10) SED = 0.23 mg/kg (10) MOS = NHEL/SED = 290 MOS = NOAEL/SED = 110 OMC NHEL = 522 mg/kg/day (1) NOAEL (13-week rat oral study) = 450 mg/kg/day (9) SED = 0.6 mg/kg (9) SED = 0.6 mg/kg (9) MOS = NHEL/SED = 870 MOS = NOAEL/SED = 750 SED, systemic exposure dose. Table 2.
Higher the PTS exposure dose, the higher the level of methylation of LMO2, IL10 and GSTM1 - genes known to have key roles in immune function, which could provide a mechanistic link to asthma risk.
Hypothetical population effect response level as function of population exposure dose indicating that a certain fraction of the exposed population is above a defined threshold for a given exposure distribution.
The values of the variables corresponding to medical examination before initial practical training, grounding equipment inspections, electric current, regularity of radiation safety committee meetings, and notification of expected maximum exposure dose were comparatively low, there is room for improvement in all four of the categories that were identified using the Haddon Matrix.
It indicated that at present CP exposure dose and time, did not significantly affect the red blood cell formation.
where EDY = estimated exposure dose of sludge in grams per person per year; EEDD = estimated exposure dose in grams per person per day; ETW = exposure time in days per week; EW = exposure weeks per month; EM = exposure months per year.
The greatest decrease in aggregation for collagen and ADP was observed for radiant exposure dose of 19.8 J/[cm.sup.2] (p = 0.0072 for collagen and p = 0.0108 for ADP, resp.) (Figures 3 and 4).
Experimental errors in this field are thought to be caused by age-related degradation of the system, instability of the exposure dose, and the precision of the phantom.
Based on these data the exposure dose rates to terrestrial reference organisms were evaluated using ERICA Assessment Tool (Beresford et al.
