Sample size was calculated using a web calculator (http://powerandsamplesize.com/Calculators/). It has been reported that the incidence of delirium after radical resection of colon cancer is 24% [22]. The sample size was 1: 1, α=0.05, β=0.2, and the minimum sample size was estimated...
Only pH 0.01 M CaCl2 was estimated from the measured pHH2O by using the proposed equation pHCaCl2 = − 0.54 + 1.00 × pHH2O. Statistic treatments Parametric or non-parametric tests were applied after testing normality of residues and equality of variances. Tests were performed as follows ...
(b ) Diluting solution .—To 1 L volumetric flask containing 300–500 mL H 2O, add 58 mL HNO 3 and 67 mL H 2SO 4. Dilute to volume with H 2O.(c ) Magnesium perchlorate .—Drying agent placed in filter flask (Figure 971.21). Replace as needed. [Caution: Mg(ClO 4)2 is ...
Each DNA sample was added to a well of a 96 well plate containing 10 μl 2x test/reference reaction mix, 1 μl each of forward and reverse primers (10 μM) and 3 μl H2O. After digestion, the IFNG promoter region is amplified by RT-qPCR. The Ct value ...
Heavy metal treatments A modified Allen's medium with increasing concentrations of each metal (0, 1, 10, 25, 50, and 100 mM, pH=2) was used to test the arsenite (As(III); NaAsO2, CAS #7784-46-5, Sigma-Aldrich) and arsenate (As(V); Na2HAsO4·7H2O, CAS #10048-95-0, Sigma...
