Figure Lengend Snippet: TGC and/or unloaded CD NPs ameliorated the S. Typhimurium infected group induced histopathological alterations in mice’s liver tissues. Representative photomicrographs of the H&E-stained hepatic tissue sections showing the control (A), S. Typhimurium infected group (C), TGC (E), unloaded CD NPs (G), CD-TGC groups (I) and their respective higher magnifications (B, D, F, H, and J). A, B: control group displaying normal central vein (CV), hepatic cords (HC) with hepatocytes of eosinophilic granular cytoplasm (EC), rounded central single (SN) or double vesicular nuclei (DN), and kupffer cells (KC). C, D: S. Typhimurium infected group demonstrating multiple areas of variable-sized necrotic areas (NA) of coagulative necrosis (CN), severely dilated and congested sinusoid (SDS) with Kupffer cell hyperplasia (KCH). E, F: TGC group displaying moderately sized necrotic areas (MNA), moderately dilated and congested sinusoids (MDS), moderately hyperplastic Kupffer’s cells (MKC), interstitial mononuclear cell infiltration (MI), fibroblast proliferation (FP), and regenerated hepatocytes of stippling basophilic cytoplasm (BC) and pale nuclei (PN). G, H: unloaded CD NPs group showing a few scattered minute necrotic areas (mNA), intense mononuclear cell infiltration (IMI) around the portal area, and apparently normal hepatocytes (NH). I, J: CD-TGC group showed normal hepatocytes (NH), few dilated blood vessels (DBV), and a few interstitial lymphocytic aggregates (FL). Scale bars = 100 μm in A, C, E, G, I; and = 20 μm in B, D, F, H, and J. K: Bar charts demonstrate the statistical analysis of the comparative quantification of the hepatic injury scores in all studied groups. Bars carrying different superscript letters (a, b, c, d, and e) are significantly different as analyzed by the one-way ANOVA test, followed by the multiple comparisons by Duncan’s Post-hoc test ( p < 0.05). Values are the mean of 6 mice per group ± S.E.M.

Article Title: Eriodictyol Attenuates H 2 O 2 -Induced Oxidative Damage in Human Dermal Fibroblasts through Enhanced Capacity of Antioxidant Machinery

doi: 10.3390/nu14122553

Figure Lengend Snippet: Eriodictyol inhibited H 2 O 2 -induced cytotoxicity in dermal fibroblasts. ( A ) H 2 O 2 exposure (125–1000 µM; 1 h) resulted in a concentration-dependent decrease in the viability of BJ cells. ( B ) Eriodictyol treatment (10–40 µM; 24 h) did not result in cytotoxicity in BJ cells. ( C ) Eriodictyol pretreatment (10–40 µM; 24 h) prevented H 2 O 2 -induced cytotoxicity (500 µM; 1 h) in BJ cells. Cell viability was observed using the MTT assay after the indicated treatments. The survival percentage was calculated relative to untreated controls. DMSO (0.5%) was used as a vehicle control ( n = 3; each biological replicate consisted of four independent wells; mean ± SEM). * p < 0.05 versus vehicle controls ( A ) and p < 0.05 versus H 2 O 2 -treated cells ( C ). N.S. , not significant.

Article Title: Eriodictyol Attenuates H 2 O 2 -Induced Oxidative Damage in Human Dermal Fibroblasts through Enhanced Capacity of Antioxidant Machinery

doi: 10.3390/nu14122553

Figure Lengend Snippet: Eriodictyol prevented the induction of necrosis in BJ cells following H 2 O 2 treatment. BJ cells were pre-treated with eriodictyol (5–20 µM; 24 h) followed by H 2 O 2 treatment (500 µM; 1h). After 24 h treatment with H 2 O 2 , dermal fibroblasts were co-stained with Hoechst 33342 (blue)/PI (red) to characterize mode of cell death ( n = 3; magnification = 20×; scale bar = 100 µm).
