The phrase "act concentrations" is not correct in standard written English.
It may be intended to refer to "active concentrations," which is a term used in scientific contexts, particularly in chemistry or biology.
Example: "The experiment measured the act concentrations of the various solutions to determine their effectiveness."
Alternatives: "active concentrations" or "effective concentrations."
Potential confounders considered a priori were HIV-type, sex, self-reported ethnicity (for genotype associations) and baseline absolute CD4 cell count, age, body mass index (BMI) [ 13] and ACT concentrations.
Due to the dose-dependent manner in which pinocembrin is found to act, concentrations ranging from 3.0 μM to 30.0 μM are selected for further investigation in hBMECs in the presence to fA β1 40.
Results revealed that among the process variables investigated, initial ACT concentration has the most significant effect, while interactions between photocatalyst dosage and initial ACT concentration (AB) as well as with initial pH (AC) also played important roles.
Optimized conditions are obtained at photocatalyst dosage of 0.1 g/L, initial ACT concentration of 0.1 mM, and initial pH of 6.94.
Mutlivariate analysis based on response surface methodology was employed to quantify the individual and interaction effects of three key process parameters, i.e. photocatalyst dosage (A), initial ACT concentration (B), and initial pH (C) at pre-determined ranges.
Furthermore, the internalisation process is dependent on ACT concentration (Figure S1).
The ACT concentration was quantified by counting the height of the rocket-shaped precipitation zone.
In Table 2, Models 2, adjusting for the acute phase response (APR) assessed by ACT concentration only slightly modified the magnitude of observed effects compared to the unadjusted models, and did not alter the overall interpretation.
For these reasons we also expressed cystatin C and α1-ACT concentrations relative to both albumin and creatinine (Table 3).
α1-ACT concentrations were then divided by total CSF protein concentration, and each patient collective was compared to the appropriate control group.
Similarly to the CSF analysis reported above, urinary α1-ACT concentrations of sCJD patients were compared to those of AD patients and of control group A. We found dramatically elevated urinary α1-ACT in sCJD patients (Table 3, Figure 3).
