All measurements are presented as the mean ± SD of 3 replicates (photosynthetic parameters n = 20). The data were input and analyzed by Excel 2010 software and IBM SPSS Statistics 25.0 software (IBM Corp., Armonk, NY, USA). The charts were produced by Excel 2010, Origin 2021 (Origin Lab Inc., San Francisco, CA, USA) and Adobe Photoshop 2020 (Photoshop Software, San Diego, CA, USA). The growth parameters, photosynthetic index, antioxidant system, soluble proteins, sugars, amino acids, hormones and the physical and chemical properties of substrates were analyzed by the general linear model, which is a fixed effect model. Normal distribution and homogeneity test of variance were conducted on samples before ANOVA processing, which all met the above conditions. One-way ANOVA was performed for significance testing (p < 0.05). Duncan’s test was used to compare the means of all paired measurement values. Pearson correlation coefficient was used for correlation analysis. Principal component analysis (PCA) analysis was performed with Origin 2021 (Origin Lab Inc., USA). Kaiser-Meyer-Olkin (KMO) test was conducted on sample variables, and KMO > 0.7, so PCA could be conducted.

Automated Fungal Growth Analysis

Time-lapse images (used to produce growth and germination videos) as well as time-point large images (used for measuring growth rates) were obtained with two inverted microscopes (Eclipse Ti-U and Eclipse Ti-2, Nikon; ESI Methods). Microscopy images were processed and analysed with Image J (Fiji).42 (link) To measure hyphal growth, the segmented line and measurement tool were used. The measured lengths were grouped into 5 intervals; 0.1–0.4 mm, 0.5–1.0 mm, 1.1–2.0 mm, 2.1–3.0 mm and >3 mm, and represented as stacked column diagrams using Origin 2021 (OriginLab). To account for the variation in number of spores loaded into the devices, the results were normalised. Therefore, the number of germination sites (instead of the number of spores) was determined and the absolute value of counts divided by the number of germination sites. For the hyphal growth behaviour, we counted sites where a germination within 14 days of inoculation occurred as germination sites. For calculation of the germination rates, we defined any site where usually a germination occurs from, i.e., cut ends of hyphal remnants, as a germination site. Germinations were counted at the last day, day 14, of the experiment. For determining significant differences in the data points for germination rates and spore distribution within devices, 1-way ANOVA was performed in Origin 2021 (OriginLab).

Statistical Analysis of Experimental Data

Data comparisons throughout the manuscript are presented as mean ± standard error of the mean and plotted using Origin 2021(OriginLab, USA). All data sets were analyzed using t‐test or analysis of variance (ANOVA) with Origin 2021(OriginLab, USA). In cases whereby, samples do not meet normality criteria, a nonparametric test was used. A p‐value of less than 0.05 was considered statistically significant (* indicates p < 0.05, ** indicates p < 0.01, n.s. indicates no significant).

Check if the same lab product or an alternative is used in the 5 most similar protocols
The significance of differences between two groups was analyzed using unpaired Student’s t-tests. Pearson’s correlation was performed using Origin2021 software (Origin Lab Corporation) to determine
associations between two continuous variables. To compare the sensitivity of the bead-based IgG antibody assay with that of the ELISA, the LOD and LOQ were calculated using a serially diluted anti-SARS-CoV-2 RBD neutralizing antibody (AcroBIOSYSTEMS). For the determination of the LOD and LOQ values, the limit of blank (LOB) was considered. The LOB was calculated by the mean of the blank + 1.645 (standard deviation of the blank), and the LOD was calculated by LOD = 3.3 × σ / S, where S is the slope of the calibration curve, and σ is the standard deviation of the Y-intercept. The LOQ was calculated by LOQ = 10 × σ / S (16 (link)). Standard dilution series obtained for the ELISA and bead-based IgG antibody analysis were used to determine the LOD and LOQ. For linear regression to obtain a calibration curve, data with a range higher than the LOB were analyzed using Origin2021 software (Origin Lab Corporation). All data are expressed as the mean ± SD. For all statistical tests, P-values ≤ 0.05 were considered significant.

Thermal Denaturation Analysis of SARS-CoV-2 in Human Whole Blood

Check if the same lab product or an alternative is used in the 5 most similar protocols
Differential scanning calorimetry (DSC) is a thermoanalytical technique to study the thermodynamic properties of biological and non-biological samples [47 (link),48 (link),49 (link),50 (link),51 ]. To investigate the effect of SARS-CoV-2 on the human whole blood, thermal denaturation measurements were performed with SETARAM Micro DSC-III calorimeter. Each measurement was performed in the range of 20–100 °C by using a 0.3 K·min−1 heating rate. The sample and the reference (normal saline) were balanced with a precision of ±0.05 mg to avoid corrections with the heat capacity of the vessels. A second thermal scan of the denatured sample was carried out for baseline correction. The deconvolution of DSC data, the analysis of the melting temperature (Tm), and the calculation of the relative enthalpy change (ΔH) from the area under the deconvolved heat absorption curves were analyzed using the OriginLab Origin® 2021 (version 9.8.5.212) software (OriginLab Corporation, One Roundhouse Plaza, Suite 303, Northampton, MA 01060, USA).

Raman Spectroscopy Analysis of Materials

Raman spectra were taken using an InVia spectrometer (Renishaw, Gloucester, UK) equipped with a DM 2500 M microscope (Leica, Wetzlar, Germany) with a 50X objective. Lasers with the power of 100 mW, wavelengths of 532 nm, and a spectral resolution of 2 cm−1 were used. A spectral range of 500–2500 cm−1 was considered. The Raman spectra were deconvoluted using Gaussian line fitting (Origin 2021, Origin Lab., Northampton, MA, USA). The fitting parameters were used to calculate the Raman parameters, including band position and the spectral intensity ratios ID/IG and Imax/IC.

Membrane Crystal Structure Analysis

The crystal structure of the membranes was investigated using the X-ray diffraction method with an XRD 6000 diffractometer (Shimadzu, Kyoto, Japan). The average size of the crystallites (lc) was calculated using the Debye-Scherrer Equation (1): lc=kλCosθβ
where λ is the wavelength of the incident radiation (Cu K-alpha, λ = 1.54056 Å), β is the width of the reflection at a half height (FWHM), θ is the angle of the diffraction, and k = 0.9. The estimation of the FWHM parameter was performed by interpolating the X-ray pattern using a Gauss function (Origin 2021, Origin Lab., Northampton, MA, USA).

Check if the same lab product or an alternative is used in the 5 most similar protocols
To test the interaction effects between grazing intensities (i.e., CK, LG and HG) and soil positions (both in rhizosphere and non-rhizosphere soils) treatments on the microbial diversity and soil chemical properties, we used a two-way ANOVA with grazing treatments as the main-plot effect, and soil position treatments as the sub-plot effect. Microbial diversity was calculated based on OTUs number, including Richness, Shannon-Wiener index and Chao1 index, calculated by the following formula:
Richness = SobsShannon-Wiener index: Hshannon=i=1SobsniN lnniN
Chao1 index: Schao1 = Sobs + n1(n1 − 1)/2(n2 + 1).
Where: Sobs is the OTUs number actually observed; Schao1 is the estimated OTUs number; n1 represents the number of OTUs containing only one sequence; n2 represents the number of OTUs containing only two sequences; ni is the number of sequences contained in the i th OTUs; N represents all the sequence numbers. Besides, spearman correlation analysis was used to assess the relationships between the microbial diversity (i.e., both bacterial and fungal) and soil chemical properties. Data analysis was conducted using SPSS 19.0 (IBM Corp., Armonk, NY, USA), and all figures were prepared using Origin 2021 (OriginLab Corporation, Northampton, MA, USA).

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.
