All the data were analyzed according to the experimental design, using SPSS 22 software (SPSS Statistics 22.0, IBM, United States). Pictures were drawn by Origin 2016 (Origin 2016, OriginLab, United States) and ImageJ (ImageJ 1.8.0, National Institutes of Health, United States). The means of these parameters were compared using Duncan’s multiple range test at P < 0.05.

Whitefly Abundance Analysis via ANOVA

Check if the same lab product or an alternative is used in the 5 most similar protocols
Data for analysis of variance were transformed to log10(x), or log10(x+1) if any zeroes were present, to homogenise the variance. Residuals were checked for normality. Multiple comparisons were made using Tukey’s test. A general linear model was used for regression analysis, allowing for blocks. The data for the regression were transformed to log10(x+1) and the residuals were checked for normality. Regression on increasing shades of grey used a dummy variable where plain = 0, light grey = 1, mid grey = 2, and black = 3. All tables and figures show untransformed means and standard errors for adult whiteflies per trap, whereas all the statistical analyses used log-transformed data and allowed for blocks. Statistical analysis was carried out with Minitab 16 (Minitab Inc., USA) and measurement of the areas under curves was carried out with Origin 2016 (OriginLab Corp., USA).

Lactobacillus rhamnosus strains were grown statically for 16 h in MRS broth at 37°C. Freshly harvested cells were washed with MRS without glucose and diluted 1:100 in MRS (pH 6.6) containing either bile (0, 0.1, 0.3, 0.5, and 1.0% w/v oxgall), or adjusted to pH 4 (HCl) or pH 8 (NaOH). 200 μl of bacterial suspensions were placed into each well of a 96 well plate, sealed and placed into Tecan Infinite 200 Pro spectrophotometer (Tecan, Switzerland), where they were grown for 24 h at 37°C. Measurements of optical density at 600 nm (OD600nm) were taken every 15 min during this 24-h period. Maximum specific growth rates (μmax) were then calculated for each treatment type and plotted in Origin2016 (OriginLab, Northampton, MA).

Imaging Striatal Astrocyte Calcium Dynamics

Striatal slice preparation was performed as described above.
Striatal slices were maintained in oxygenated ACSF (124 mM NaCl, 4.5 mM KCl,
1 mM MgCl2, 1.2 mM NaH2PO4, 26 mM
NaHCO3, 10 mM D-glucose, and 2.0 mM CaCl2) through
a perfusion system. Astrocytes for all the experiments were imaged using a
confocal microscope (Fluoview 1200; Olympus) with a 40×
water-immersion objective lens with a numerical aperture (NA) of 0.8 and at
a digital zoom of two to three. We used the 488 nm line of an Argon laser,
with the intensity adjusted to 9% of the maximum output of 10 mW. Astrocytes
were chosen typically ~20 to ~30 μm below the slice
surface and scanned at 1 frame per second for imaging sessions.
Analyses of time-lapse image series were performed using ImageJ
(NIH). XY drift was corrected using a custom plugin in ImageJ. Time traces
of fluorescence intensity were extracted from the ROIs and converted to dF/F
values. For analyzing spontaneous Ca2+ signaling, ROIs were
defined in normal aCSF (control). Using Origin 2016 (Origin Lab Corp),
Ca2+ events were manually marked. Event amplitudes, half
width, event frequency per ROI per min, the integrated area-under-the-curve
(AUC) of dF/F traces were measured. Events were identified based on
amplitudes that were at least 2-fold above the baseline noise of the dF/F
trace.

Luminescence-Based Assay Optimization

S/B ratio was calculated
by μmaxmin and coefficient of
variation (CV%)
as (σ/μ) × 100. μmax and μmin are the mean values of three triplicates of luminescence
intensity signals. The Z′ factor was calculated
as . In all calculations,
σ refers as
standard deviations (SD) and μ as mean values. The half-maximal
inhibitor concentration (IC50) values and all other curves
were fitted using standard sigmoidal fitting functions with Origin
2016 (OriginLab, Northampton, MA).

Comparative Analysis of Leaf and Sink Traits

Check if the same lab product or an alternative is used in the 5 most similar protocols
The experiments were conducted as randomized block design using three biological replicates. One-way analysis of variance (ANOVA) was performed with the whole dataset to confirm the variability of data and validity of results, and Duncan’s multiple range test (DMRT) was performed to determine the significant difference between treatments. Different letters indicate significantly different values (DMRT, p ≤ 0.05). Principal component analysis (PCA) was performed with datasets of the source leaf and developing sink, using Origin 2016 (Origin Lab, Northampton, MA, USA), and the first two components (PC1 and PC2) explaining the maximum variance in the datasets were used to make biplots.

Quantitative Influenza Virus Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
The signal-to-background (S/B) ratios were calculated as µmax/µmin, specific signals as µmax-µmin, and coefficient of variations (CV%) as (σ/µ) × 100. The limit of detection (LOD) was calculated as µmin + 3SD (zero concentration), and the lower limit of detection (LLD) as 3SD. In these formulas, µ is the mean value and σ is the standard deviation (SD). The TEM picture analysis and virus particle calculations were performed using Trainable Weka Segmentation for training a random forest classifier to detect viruses from the TEM images. The plug-in was then used to count the objects that fit the size range and circularity typical for influenza viruses from the segmented binary images [42 (link)]. All data was analyzed and figures were drawn with Origin 2016 (OriginLab, Northampton, MA, USA) using standard fitting functions.

Multivariate Analysis of Optical Metrics

The statistical difference between multiple parameters was tested by Tukey-Kramer's multiple comparisons of means. Linear regressions were fitted using the ordinary least squares method with log10 transformation of variables when needed. Correlations among Fmax/DOC values of the identified PARAFAC components were evaluated using Spearman's rank correlation coefficient (ρ).
A significance level of 0.05 was selected for multiple comparisons to test the null hypothesis. Linear correlations were considered statistically significant when P < 0.01. All analyses were conducted with Origin 2016 (OriginLab Corporation, MA, USA).

Multivariate Analysis of Wine Volatiles

Statistical data processing was performed using the software Statistical Product and Service Solutions (SPSS 20.0) for Windows (IBM, Armonk, NY, USA). Statistical analyses of the data were performed using one-way analysis of variance (ANOVA) and Duncan’s test at the p < 0.05 level. To obtain an overview of the different wine samples, the data of volatile compounds and phenols were subjected to principle component analysis (PCA) to visualize all information in the data set. All plots were prepared using Origin 2016 (OriginLab Corporation, Northampton, MA, USA).

Spectral Analysis with Multivariate PLS-DA

Check if the same lab product or an alternative is used in the 5 most similar protocols
Spectra were analyzed and plotted using Origin 2016 (Origin Lab Corporation, MA, USA). Multivariate analysis was carried out using the MATLAB (2016, Math Works, Inc., MA) version of PLS-Toolbox (v8.0 Eigenvector Research Inc., WA). First derivative and smoothing was done for all the spectra by the Savitzky-Golay (SG) method using a 2nd order polynomial with a 9 point data window. All spectra were normalized using the standard normal variate method and mean centered before applying multivariate analysis. Partial Least Squares-Discriminant Analysis (PLS-DA) was performed on the preprocessed data and the robustness of the model was verified by cross-validation using Venetian blinds algorithm with 10 data splits, which calibrates the classification model based on 90% of the data, tests the remaining 10% against that model, and repeats the process through ten iterations to assess its predictive power.

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.
