The results showed that among the key target genes, CCNA2 expression was upregulated, and ABL1, CDK4, CDKN1A, IGFR and MAP2K1 expression was downregulated after TGYP treatment, while the expression of PGR was below the limit of detection (Fig. 7A). Cause these regulated genes were closely...
Residuals for all hormones were more symmetric after transformation, and we presented the analyses based on the transformed values. Since few samples reported as below the limit of detection (LOD), we used listwise deletion method for missing data43. In adults, where the concentration of a urine...

Used this formula because Im averaging lab results and if they are below detection limit (<) then it takes half of the number. It also eliminates the error if there are zeros in case numbers arent filled in yet Click to expand... I can see three serious problems: The "IfError" functio...
The strategy of the relationship between formula and efficacy researching has changed in the past few decades. It cannot limit to a single herb, but also needs to be considered as a whole. The multi-dimensional properties of TCM determines the efficacy of the prescription. Subsequently, some sch...

In the semi-quantitative survey, the general detection limit for metals was <0.1 ug/l(4). Gold concentrations in the Alamosa River, CO (Jun and Sept 1994) and the Big Arsenic Springs, MN (Sept 1994) were 0.92, 1.0, and <0.01 ug/l, respectively(5).|RAIN/SNOW/FOG: Gold ...
The Stark tuning of the low- J levels of the $ilde X{}^1A^\prime $ X 1 A ′ (000) state were analyzed to give a value of 3.968(32) D for the a -component of the permanent electric dipole moment, μ a . An upper limit of 0.3 D for μ a ( $ilde B{}^1A^{\prime \...
