Atrazine is not sold in Europe after a vote by the European Union in 2003 in response to campaigns by advocacy groups over trace amounts found in groundwater at levels well below safety cut off standards in the US and Australia.
We calculated standard deviations for parallel samples, set cut-off standard to one, and quantified gene expression based on normalization with the control and self-normalization in parallel samples.
For each specimen relative light unit/cutoff values were calculated as the ratio of the specimen luminescence relative to the luminescence of the 1.0 pg/ml HPV-16 cut-off standard and reflect a semi-quantitative value of the cumulative viral burden from one or more of the examined genotypes.
*97 hours was used as cut off point as standard infusion time was 96±± 1 hr.
Two commonly used cut-off standards for low QOL have been proposed, namely, "70% of the maximum score" and "one SD below the mean" [ 19, 20].
Based on BMI and WC cut-offs standards associated with the Chinese population, the prevalence of overweight, obesity and abdominal obesity was 27.8%, 5.7% and 38.8%, respectively, in rural Hanzhong, Shaanxi province.
RNA-seq detected a greater total number of DE genes than the microarray (1,037 versus 374, respectively, using the standard cut off criteria).
A full CART algorithm adds nodes until they are homogenous or contains few observations (≥5 is the standard cut off in S-Plus).
To assess reliability, internal consistency was evaluated by calculating the Cronbach's α statistic using the standard cut off point of 0.7 [ 17].
