All hemodynamic variables were expressed as the mean value ± standard deviation (SD). Hemodynamic changes for each coronary anastomosis were compared to baseline measures using repeated measures of ANOVA. The comparisons of variables between coronary arteries were analyzed with one-way ANOVA. A p-value of < 0.05 was considered as statistically significant. Data analysis was performed with SPSS 19 statistical software for windows (version 19; IBM Corp., NY, USA).

For the geochemistry analysis, the freeze-dried samples were homogenized in an agate mortar, and then completely digested by HCl-HNO 3 -HF-HClO 4 in Te on beakers. The concentrations of aluminum (Al) and Zn were measured by inductively coupled plasma-atomic emission spectrometry (ICP-AES; Leeman Labs, Pro le DV), while the concentrations of arsenic (As), Cd, chrome (Cr), copper (Cu), nickel (Ni), and Pb were measured by inductively coupled plasma mass spectrometry (ICP-MS; Agilent 7700 ×). The detection limits of the analytical procedure are 20 (Al), 1 (Ti), 0.2 (Zn), 0.1 (As), 0.01 (Cd), 0.1 (Cr), 0.02 (Cu), 0.05 (Ni), and 0.01 (Pb) mg kg - 1 , respectively. Data quality was ensured by measuring blanks and standard reference materials (GBW07358; Chinese geological reference materials) after every tenth sample. The accuracy, expressed as a recovery of the reference material, was 92.8-106.3% for the metals except for Sb (113.5%). Factor analysis was performed using IBM SPSS19 statistical software for Windows to determine the relationships among the major and trace metals.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
