Figure Lengend Snippet: Establishment of MASLD pathophysiology in mice by CD-HFD feeding for 20 weeks. (A) Schematic representation of the experimental mouse groups: LEAN [ n = 6; chow diet-fed mice for 20 weeks] and MASLD [ n = 6; CD-HFD fed mice for 20 weeks]. (B) Liver weight (grams), and (C) liver-to-body weight ratio of the LEAN and MASLD mouse groups. Serum levels of (D) ALT (U/L), (E) AST (U/L), (F) hepcidin (ng/mL), and (G) ferritin (μg/mL) in the LEAN and MASLD groups. Formalin-fixed, paraffin-embedded 5 μm liver slices from the LEAN and MASLD groups were used for histopathological analyses. Representative images of (H) hematoxylin and eosin (H&E) staining, picrosirius red (PSR) staining, and immunohistochemistry images depicting α -SMA, and IL-1β immunoreactivity (indicated by black arrowheads) in the liver sections of LEAN and MASLD mouse groups. H&E and immunohistochemistry images were captured at 200× magnification, whereas PSR images were captured at 100× magnification. (I) NAFLD activity score (NAS) and fibrosis score for the LEAN and MASLD groups. Morphometric analyses (calculated as %ROI) of (J) PSR staining, (K) α -SMA, and (L) IL-1β immunoreactivity, where the Y-axis represents % positive immunoreactive area ( n = 3; mean value taken from three separate microscopic fields). The data are presented as mean ± SEM, and statistical significance was tested using unpaired t-test between the two groups, followed by Bonferroni post-hoc corrections (* p < 0.05, ** p < 0.01, *** p < 0.001).

Article Title: Sex similarities and divergences in systemic and muscle iron metabolism adaptations to extreme physical inactivity in rats

doi: 10.1002/jcsm.13547

Figure Lengend Snippet: Graphical abstract illustrating the impact of extreme physical inactivity and sex on iron metabolism systemic regulation in rats. Unlike in humans, female rats exhibit higher serum, liver, and spleen iron concentrations and serum hepcidin levels than male rats in their basal state. However, there is no difference in iron concentration in the soleus muscle between the sexes in the basal state. In response to 7 days of hindlimb unloading, while both inactive males and females do not show altered plasma iron availability, only males present an increase in spleen and liver iron concentrations and serum hepcidin. However, both sexes exhibit an increase in iron concentration in the soleus muscle. This image was created with BioRender.com .

Article Snippet: Serum hepcidin (S‐1483, BMA Biomedicals, Switzerland) concentrations were measured by enzyme‐linked immunosorbent assay, according to the manufacturer's instructions.
