essing tools as implemented by the manufacturer (Application release VE11E) [22]. Fat fraction was analyzed in three ROIs in every liver from the WD- and SD-fed mice. 2.five.three. Assessment of Hepatocyte Uptake Capacity T1-maps were acquired before, also as just after a single hour of gadoxetic acid injection. Three-dimensional T1-weighted spoiled gradient echo images had been acquired with differentCells 2021, 10,7 ofexcitation flip angles (coronal VIBE, TR 7.92 ms, TE 2.44 ms, flip angle 2 /5 /15 /20 /25 , 0.three 0.3 0.4 mm spatial resolution, accelerated applying CAIPIRINHA with PAT issue four, 6 averages to compensate for respiratory motion). Pixel-wise nonlinear least-squares fitting was applied working with home-built computer software in Python three.8 and SciPy 1.7 to retrieve pre- and post-T1-maps. T1-maps have been calculated from pre- and post-T1-maps as T1 is recognized to correlate with hepatocyte uptake and negatively correlates with liver function [23]. Relative transform in T1 relaxation time was calculated (RE = T1/T1pre, exactly where T1pre reflects the T1-value before injection of contrast agent) to reflect liver function. Subtractions of preand post-contrast photos acquired with flip angle 20 were made use of to visualize uptake in the contrast agent. 2.6. Sample Collection Blood, at the same time as liver tissue samples, were collected time-dependently (Figure 1A) from defined anatomical positions of anesthetized mice, as previously described [24,25]. 2.7. Liver Enzyme Assay Activities of transaminases (ALT and AST), at the same time as alkaline phosphatase (AP) in heart blood, were measured making use of the Piccolo Xpress Clinical Chemistry Analyzer (Hitado, Germany). 2.8. Histopathology, Immunohistochemistry, and TUNEL Staining Hematoxylin and eosin (H E), Sirius red, immunohistochemistry, at the same time as TUNEL stainings had been performed in 4 thick PFA (4 )-fixed paraffin-embedded liver tissue sections working with the Discovery Ultra Automated Slide Preparation Technique (Roche, Germany), as previously described [26,27]. Commercially offered kits have been applied for staining of TUNEL (Promega, Germany) and Sirius red (Polysciences Europe GmbH, Germany), in line with the manufacturers’ instructions. Immunohistochemistry was performed using the precise antibodies listed in Table five. Following staining, whole slide scanning was undertaken utilizing a digital scanner (Axio Scan.Z1, Zeiss, Germany).Table five.
