They are small and move fast in the water. Real-time imaging of fast-moving zebrafish is a challenge, and it requires that the imaging technique has higher spatiotemporal resolution and penetration ability. The purpose of this study was to evaluate the feasibility of dynamic phase retrieval (PR)-based phase-contrast imaging (PCI) for real-time displaying of the breathing and swimming process in unanesthetized free-moving zebrafish, and to evaluate the feasibility of PR-based phase-contrast CT (PCCT) for visualizing the soft tissues in anesthetized living zebrafish. PR was performed using the phase-attenuation duality (PAD) method with the δ/β values (PAD property) of 100 and 1000 for dynamic PR-based PCI and PR-based PCCT, respectively. The contrast-to-noise ratio (CNR) was used for quantitatively assessing the visibility of the adipose tissue and muscle tissue. The skeleton and swim bladder chambers in fast-moving zebrafish were clearly shown. The dynamic processes of breathing and swimming were visibly recorded. The respiratory intensity and frequency and the movement flexibility of the zebrafish could be dynamically evaluated. By producing more obvious image contrast, PR-based PCCT clearly showed the adipose tissue and muscle tissue. The CNRs from PR-based PCCT were significantly higher than those from PR-free PCCT for both adipose tissue (9.256 ± 2.037 vs. 0.429 ± 0.426, <i>p</i> < 0.0001) and muscle tissue (7.095 ± 1.443 vs. 0.324 ± 0.267, <i>p</i> < 0.0001).

However, high concentrations and toxic side effects of Mtz severely limit the application of the Mtz/NTR system. Therefore, screening new analogs to replace Mtz has become an important means to optimize the NTR ablation system. In this study, we screened five Mtz analogs including furazolidone, ronidazole, ornidazole, nitromide, and tinidazole. We compared their toxicity on the transgenic fish line <i>Tg(fabp10a: mCherry-NTR)</i> and their specific ablation ability on liver cells. The results showed that Ronidazole at a lower concentration (2 mM) had the same ability to ablate liver cells comparable with that of Mtz (10 mM), almost without toxic side effects on juvenile fish. Further study found that zebrafish hepatocyte injury caused by the Ronidazole/NTR system achieved the same liver regenerative effect as the Mtz/NTR system.

Low concentration of digestive enzyme (0.5 mg/mL collagenase type II) was utilized in our protocol to obtain single-cell suspension. The ventricles were fragmented, mechanically pipetted, and constantly shaken to ensure adequate contact between the tissues and the enzyme. Preplating the cell suspension onto culture plates for 2 h helped remove cardiac fibroblasts. The purity of isolated cells was validated by flow cytometry analysis of transgenic zebrafish with cardiomyocyte-specific expression of enhanced green fluorescent protein (EGFP) or endothelial cell-specific expression of mCherry. Quantitative real-time PCR analysis revealed a high level of the purity, with cardiac fibroblasts, endothelial cells, and epicardial cell markers scarcely detected in the purified cells. Altogether, this study established a reproducible protocol for isolating primary cardiomyocytes with high purity and activity from adult zebrafish hearts that can be cultured <i>in vitro</i> for up to 4 weeks.

Tetrahydroxystilbene glucoside (TSG) is a natural component isolated from Heshouwu (<i>Polygonum multiflorum</i> Thunb.). It has been widely used to treat various chronic diseases for its remarkable biological activities. In this study, we successfully established aging larval zebrafish by exposing larvae to 2 mM hydrogen peroxide (H₂O₂). Using this aging model, we assessed the antiaging effect of TSG with different concentrations (25-100 μg/mL). After being treated with H₂O₂, zebrafish showed the obvious aging-associated phenotypes characterized by higher senescence-associated β-galactosidase activity, significantly downregulated expression of sirtuin 1 (<i>sirt1</i>) and telomerase reverse transcriptase (<i>tert</i>), and upregulated <i>serpine1</i> mRNA level compared to the control group. TSG pretreatment delayed the aging process of oxidative stress-induced zebrafish, indicative of the reduced positive rate of senescence-associated β-galactosidase, improved swimming velocity, and stimulus-response capacity. Further studies proved that TSG could suppress reactive oxygen species production and enhance the activity of antioxidant enzymes superoxide dismutase and catalase.
