... High aquacultural rearing density and handling of fish may frequently result in skin or gills wounds, thereby facilitating the onset of secondary infections. The capacity of the zebrafish to regenerate tissues, as well as fins and other organs, makes it an ideal animal model for studying the mechanisms of tissue regeneration. Since macrophages are involved in tissue regeneration, a diet including ...
... Aquatic herbicides are used worldwide to eradicate nuisance and invasive plants despite limited knowledge of their toxicity to non-target organisms. 2,4-Dichlorophenoxyacetic acid (2,4-D) is a common active ingredient in commercial herbicide formulations, which triggers plant cell death by mimicking the plant-specific hormone auxin. Application practices of 2,4-D commercial herbicides typically co ...
... Precise in vivo toxicological assays to determine the cardiotoxicity of pharmaceuticals and their waste products are essential in order to evaluate their risks to humans and the environment following industrial release. In the present study, we aimed to develop the sensitive imaging-based cardiotoxicity assay and combined 3D light-sheet microscopy with a zebrafish model to identify hidden cardiova ...
... Nematode parasites have a profound impact on humankind, infecting nearly one-quarter of the world’s population, as well as livestock. There is a pressing need for discovering nematicides due to the spread of resistance to currently used drugs. The free-living nematode Caenorhabditis elegans is a formidable experimentally tractable model organism that offers key advantages in accelerating nem ...
... In search of the molecular identities of cold-sensing receptors, we carried out an unbiased genetic screen for cold-sensing mutants in C. elegans and isolated a mutant allele of glr-3 gene that encodes a kainate-type glutamate receptor. While glutamate receptors are best known to transmit chemical synaptic signals in the CNS, we show that GLR-3 senses cold in the peripheral sensory neuron ASER to ...
... Acute myeloid leukemia (AML) is one of the most frequent, complex, and heterogeneous hematological malignancies. AML prognosis largely depends on acquired cytogenetic, epigenetic, and molecular abnormalities. Despite the improvement in understanding the biology of AML, survival rates remain quite low. Animal models offer a valuable tool to recapitulate different AML subtypes, and to assess the pot ...
... The intracellular viscosity is closely related to many functional disorders and diseases. Especially, abnormal mitochondrial viscosity changes are one of the distinct indications in metabolite diffusion as well as mitochondrial metabolism. In this work, we report a novel fluorescent probe (NI-VIS), which uses quinoline as an acceptor group and employs a TICT mechanism (twisted intramolecular charg ...
... The development of nanotechnology has drawn increased attention to the risks of nanoparticles (NPs). In this work, the near-infrared persistent luminescence imaging technique was used to track the biodistribution of NPs in vivo in zebrafish. Zebrafish were used as a vertebrate animal model to show NPs distribution and the effects of exposure. ZnGa₂O₄:Cr (ZGOC) was chosen as the probe in this work. ...
... H₂S is an important signaling molecule in living systems and participates in a series of physiological and pathological processes. In situ and rapid detection of H₂S levels in living systems is of great importance to the in-depth study of its physiological and pathological roles. Herein, we present a new fluorescent probe (DFAN) for the detection of H₂S in live cells and zebrafish. The probe DFAN ...
... Ratiometric fluorescent probes have shown great potential for optical sensing and have been widely used for bioimaging. However, due to extremely stringent molecular design, most conventional organic ratiometric fluorescent probes can only achieve one single ratio. Currently, the detection of a target in living systems in a multiratiometric manner is prominently challenging. Therefore, it is of gr ...
... We have established a zebrafish model system that will allow unprecedented access to the role of selenoprotein function during development. The work described here focuses on a poorly characterized RNA binding protein that is similar to SECIS binding protein 2 (SBP2), which is required for the co-translational insertion of selenocysteine at select UGA codons in selenoprotein mRNAs. This protein, S ...
... Sulfur dioxide (SO₂) derivatives play critical roles in various biological processes. Therefore, effective methods for monitoring SO₂ are of vital importance in bisulfite/sulfite biology. In this study, a two-photon (TP) imaging probe (CQ-SO₂) for detecting SO₂ derivatives was designed and constructed, based on the chromenoquinoline (CQ) fluorophore and a β-chlorovinyl aldehyde sensing moiety. The ...
... A novel fast-responsive two-photon fluorescent probe NS-ClO was constructed for imaging endogenous HClO in living cells, tissues and fresh zebrafish with a large turn-on signal (about 860 times) and Stokes shift (about 90 nm). The probe NS-ClO for the recognition of HClO in vivo exhibited fast response (about 1 min) and good selectivity; thus, it might be a useful tool to understand the role of HC ...

Abstract:
... Achyranthes bidentata is used as a medicinal herb prescribed for the treatment of osteoporosis in China. The anti-osteoporosis activity of the crude polysaccharide from A. bidentata, AB50, was evaluated by ovariectomized rats. The results indicated that AB50 has prominent osteoprotective effects, which was comparable to positive control. To further explore which ingredients are responsible for the ...

... Hypochlorous acid (HOCl) is closely related to human health and is widely used in our daily lives. Accordingly, detection of HOCl in live organisms and natural water samples is significantly important to human and animal health. In this paper, a novel chromogenic and fluorogenic probe (PI) was prepared for HOCl detection with high sensitivity and specificity. PI exhibits weak fluorescence emission ...
... Multi-walled carbon nanotubes (MWCNTs) have widespread use in industrial and consumer products and great potential in biomedical applications. This leads to inevitably their release into the environment and the formation of their toxic effects on organisms. These effects can change depending on their physicochemical characteristics. Therefore, the toxicological findings of MWCNTs are inconsistent. ...
