In order to investigate the scanner’s capability to image small animals, we imaged three C57 BL/6 J mice with three different radiotracers. One mouse was administered 18.5 kBq of 18F-sodium fluoride via IV tail injection, anesthetized with 1.5% isoflurane following 1 h of awake uptake and then scanned for 30 min. Images were reconstructed using four different algorithms: 2D FBP (ramp filter, cutoff at Nyquist frequency) preceded by Fourier rebinning of the 3D sinograms, 3DRP (no filter), OSEM 2D (16 subsets, 4 iterations) and fast OSEM3D/MAP (2 OSEM3D iterations, 18 MAP iterations). All images were 128 × 128 pixels with a 0.77 mm pixel size. The second mouse was injected with 32.2 MBq of 18F-FDG and scanned for 60 min, starting at 70 min post-injection. The animal was fasted for 24 h before 18F-FDG administration. A third mouse was injected IV with 32.7 MBq of 18F-fallypride (dopamine D2/D3 radioligand) and was imaged for 150 min. In addition to the emission scans, transmission images were acquired for each animal using the Co-57 source and attenuation maps were constructed after sorting in sinograms using SSRB. All animal images were reconstructed using FBP with a ramp filter and cutoff at Nyquist frequency.

Ground feed samples were analyzed according to the official methods in Germany (Verband Deutscher Landwirtschaftlicher Untersuchungs- und Forschungsanstalten (VDLUFA), 2007 ) for DM (method no. 3.1), and CP (no. 4.1.1). Pulverized ileum digesta samples also were analyzed for CP. Pulverized feed and digesta samples were analyzed for P, Ca, and Ti using a modified method from Boguhn et al. (2009 (link)), described in detail by Zeller et al. (2015a (link)).
The extraction and measurement of InsP3–6 isomers in feed and digesta were carried out using the method of Zeller et al. (2015a (link)) with slight modifications. Briefly, samples were extracted twice with a solution of 0.2 M EDTA and 0.1 M sodium fluoride (pH 8.0; 4°C) for 30 min under agitation, and centrifuged after each extraction at 12,000 × g for 15 minutes. The respective supernatants were combined, and a 1-mL sample was centrifuged at 14,000 × g for 15 min, and then filtered before being centrifuged again at 14,000 × g for 30 minutes. Filtrates were analyzed using high-performance ion chromatography and UV detection at 290 nm after post-column reaction with Fe(NO3)3 in HClO4 using an ICS-3000 system (Dionex, Idstein, Germany). Some InsP3 isomers could not be identified because the specific standards were unavailable. A clear discrimination between the isomers Ins(1,2,6)P3, Ins(1,4,5)P3, and Ins(2,4,5)P3 was not possible because of co-elution, and therefore the term InsP3x will be used for these InsP3 isomers of unknown proportions. InsP6 was used for quantification, and correction factors for differences in detector responses for InsP3–5 were used according to Skoglund et al. (1997 ). For the analysis of the InsP1–2 isomers that were analyzed solely in the ileum digesta, an extraction was performed with 0.2 M sodium fluoride at pH 8.0, and otherwise carried out as previously described for InsP3–6 isomers. Filtrates were analyzed by high-performance ion chromatography and conductivity detection using an ICS-3000 system (Dionex, Idstein, Germany). A clear discrimination between the isomers Ins(1)P1 and Ins(2)P1 was not possible because of co-elution, and therefore the term InsP1x will be used for the InsP1 isomers of unknown proportions.
For analysis of MI, samples of feed and digesta were derivatized without sample cleanup. Proteins from plasma samples were precipitated by addition of acetonitrile, and samples were lyophylized prior to derivatization. A 2-step derivatization procedure comprising oximation and silanisation was carried out. Deuterated MI was used as internal standard. MI was measured using a 5977A gas chromatograph/mass spectrometer of Agilent (Waldbronn, Germany).
Analysis of AA was performed according to Rodehutscord et al. (2004 (link)). In brief, samples were oxidized in an ice bath using a mixture of hydrogen peroxide, phenolic formic acid solution, and phenol. Then, samples were hydrolyzed at 113°C for 24 h in a mixture containing hydrochloric acid and phenol. Norleucine was used as an external standard. AA were separated and detected using an L-8900 Amino Acid Analyzer (VWR, Hitachi Ltd, Tokyo, Japan). Methionine and cysteine were determined as methionine sulfone and cysteic acid, respectively. The concentrations of tyrosine, histidine, and phenylalanine may be affected to some extent by the oxidation procedure (Mason et al., 1980 (link)).
Feed samples were analyzed for phytase activity by Enzyme Services and Consultancy (Ystrad Mynach, Wales, UK) using the analytical method of the enzyme producer (pH 4.5; 60°C), followed by transferring the results to the commonly used FTU per kilogram of feed by a validated transfer factor.

For Gi1/scFv16 crystallization, separately purified and concentrated Gαi1, Gβ1γ2C68S and scFv16 were mixed at a 1:1:1.2 molar ratio and incubated for 30 min at 24 °C. The resulting Gi1/scFv16 complex was purified from uncomplexed subunits and free scFv16 by SEC in the buffer containing 20 mM Hepes pH7.5, 100 mM NaCl, 1 mM MgCl2, 10 μM GDP and 100 μM TCEP. Purified Gi1/scFv16 was incubated with 1 mM aluminium chloride and 50 mM sodium fluoride for 1 h on ice, concentrated to 10–15 mg/mL and crystallized using the hanging drop vapour diffusion method at 20 °C against a reservoir solution containing 10% PEG 8000, 0.1 M Sodium citrate pH 5.0, 1 mM MgCl2, 10 μM GDP, 100 μM TCEP, 1 mM aluminium chloride and 10 mM sodium fluoride. Crystals appeared within a few hours and grew to the full size in 5 days. Crystals were soaked into the reservoir solution supplemented with 25% glycerol as a cryo-protectant and flash frozen in liquid nitrogen. The X-ray data set was collected at the experimental station 12-2 in the Stanford Synchrotron Radiation Lightsource. Diffraction data were integrated by XDS36 (link), scaled and merged by AIMLESS37 (link). The structure was solved by the molecular replacement in Phaser38 (link) using the heterotrimeric Gi-protein (1GP2) and scFv fragment (4NKD) as independent search models. Manual model building was performed in Coot39 (link) and refinement was performed with Phenix refine40 (link),41 (link). Ramachandran statistics are favoured 96.6%, allowed 3.4%, outlier 0.0%.

After harvesting, the cells were lysed in 50 mM Tris-HCl (pH 8.0) containing 150 mM NaCl, 1% nonidet P-40, protease inhibitor cocktail, 1 mM phenylmethane sulfonyl fluoride, 25 mM sodium fluoride, and 1 mM sodium orthovanadate. Protein concentrations were determined using BCA Protein Assay Kit (Pierce, Rockford, IL, USA). Subsequently, cellular extracts (45~60 μg) were separated with sodium dodecyl sulfate-polyacrylamide gel electrophoresis and transferred onto a polyvinylidene fluoride membrane. Non-specific binding was blocked with 5% skim milk in Tris-buffered saline with Tween 20 for 30 min at room temperature. The membranes were then incubated with the primary antibody (1 : 1,000) overnight at 4°C and continually with the secondary antibody (1 : 5,000) at room temperature for 30 min. After incubation, the membranes were washed three times for 10 min each. Proteins were visualized using ECL reagent, and the band intensity was measured using a Chemidoc XRS densitometer system and quantified by Quantity One software (Bio-Rad).

Analysing biological samples enables us to objectively evaluate biomarkers that act as an indicator of a person’s health. Biomarkers can also provide an early indication of disease before symptoms arise, provide us with information on disease progression and/or suggest therapies. In NICOLA, non-fasting venous blood samples were obtained from consenting participants. These included blood serum, plasma (EDTA/clot activator), glucose (potassium oxalate/sodium fluoride) and RNA (PAXgene). A spot urine sample was also obtained from all participants. All biological samples were transported in temperature controlled containers to a central laboratory and processed within 4 h. Aliquoted samples were subsequently frozen at − 80 °C until analysis. A dedicated courier service was used for transporting samples collected at the home-based assessments. As described previously, detailed laboratory analysis was conducted on all of the samples which included multi-omic biomarkers, lipid profiling, dietary biomarkers, inflammatory biomarkers and hormones [3 ]. All laboratory assays were standardised against available international standards, and quality control samples were included in every run. Participants consented separately for the collection of blood, DNA, urine, retinal images, facial photograph and the administration of the eye drops including consent for analysis, storage and future contact. Data are currently available for 28 biochemical biomarkers from 3082 participants within the NICOLA cohort. Participants were also offered rapid testing and feedback from blood glucose and lipid levels. NICOLA has a strong focus on molecular biomarkers and complementary genetic, epigenetic and transcriptomic data is available for a subset of participants. There is also 551,830 directly genotyped and 18,148,478 imputed SNPs currently available for 2969 participants.

Following the standardized study protocol, data were collected via detailed questionnaires, physical examination, and blood samples during baseline and follow-up visits at a local clinic. Trained clinical staff administered standardized questionnaires and conducted in-person interviews to collect information on demographic data and medical, family, and medication history. Blood pressure, height, body weight, and waist circumference were measured according to standard procedures, and body mass index (BMI) was calculated as weight (kg)/height squared (m2).
At each clinic visit, a 75-g oral glucose tolerance test (OGTT) was performed after collecting a fasting blood sample. FPG, HbA1c, fasting lipids, and 2hPG levels were also measured. After collecting venous blood, all samples were immediately placed on ice to maintain stability. Thereafter, the samples were instantly transported to the laboratory at the First Medical Centre of Chinese PLA General Hospital and processed within 2 h of blood collection. For plasma glucose (including FPG and 2hPG), blood samples were collected in tubes containing sodium fluoride and measured using the hexokinase method. HbA1c was measured using high-performance liquid chromatography (VARIANT II system, Bio-Rad, Hercules, CA). Total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) levels were determined using an auto-analyzer (ARCHITECT c16000 System; Abbott Laboratories, Chicago, IL). The quality control protocol for laboratory assays has been published in detail elsewhere (17 (link)).
The diagnosis of dysglycemia (including pre-diabetes or diabetes) was based on OGTT, conforming to the American Diabetes Association criteria (1 (link)). Pre-diabetes was defined as follows: FPG: 100–125 mg/dL (5.6–6.9 mmol/L); or 2hPG during 75 g OGTT: 140–199 mg/dL (7.8–11.0 mmol/L). Diabetes was defined as: documented diagnosis of diabetes in medical records or taking glucose-lowering medications; FPG ≥126 mg/dL (7.0 mmol/L); or 2hPG ≥200 mg/dL (11.1 mmol/L) during 75g OGTT. Normoglycemia was described as FPG <100 mg/dl (5.6 mmol/L) with 2hPG <140 mg/dl (7.8 mmol/L) during 75g OGTT. The primary study outcome was the occurrence of diabetes, defined as diagnosed (i.e., physician-diagnosed diabetes or use of antidiabetic medication during follow-up) or undiagnosed (based on the above diabetes criteria).

In this study, the sample size measured by post hoc power analysis using GPower (version 3.1.9.4, Win) for one-way ANOVA tests assuming α = 0.05 and a power of 0.80. Based on this assumption, a sensitivity analysis was carried out based on the anticipated sample size (N = 70, control = 10, N1 = N2 = N3 = 20), resulting in a minimum detectable effect size of Cohen's d = 0.379. This effect size was nearly similar to the previous study [3 (link)].
