Based on the literature survey, several concentrations of carbofuran (10, 100 and 200 μmol/L) were prepared to select the maximum effective concentration (without inducing toxic morphological abnormality). However, whether zebrafish can also regenerate lesions caused by cell death has not been tested. The zebrafish can reach up to 4–5 cm (1.6–2.0 in) in length, although they typically are 1.8–3.7 cm (0.7–1.5 in) in the wild with some variations depending on location. Zebrafish regenerate cardiac tissue through proliferation of pre-existing cardiomyocytes and neovascularization.  Though zebrafish genes may not be the exact same as human genes, these tests could provide important insight into possible genetic causes and treatments for human genetic obesity. It should be noted that the maximum temperature of 38.6 °C is close to the thermal limits of zebrafish (see Section 2). In young zebrafish larvae, the theoretical resolution limit set by intercone distances, the Nyquist frequency, is greater than 0.34 cycles/degree (less than 3° of the visual field) after 4 dpf (Easter and Nicola, 1996), while grating acuity does not exceed 0.16 cycles/degrees (6°) at 5–7 dpf in wildtype (Rinner et al., 2005). The morpholino is able to integrate into most cells of the embryo. The species is also studied to better understand the development of the retina; in particular, how the cone cells of the retina become arranged into the so-called 'cone mosaic'. The embryo begins as a yolk with a single enormous cell on top (see image, 0 h panel), which divides into two (0.75 h panel) and continues dividing until there are thousands of small cells (3.25 h panel). , Muscular dystrophies (MD) are a heterogeneous group of genetic disorders that cause muscle weakness, abnormal contractions and muscle wasting, often leading to premature death. The size of this type ranges from 180-310 µm (Wichterman, R., 2012. This represents a great decrease in the lower mass limit for fish to be tagged compared with other tags available on the market and therefore creates the possibility of tagging very young individuals of larger fish species in order to conduct long-term life history monitoring, as well as providing a means of tagging small model species such as zebrafish. They have been used to study osteogenesis (bone formation), evaluating differentiation, matrix deposition activity, and cross-talk of skeletal cells, to create and isolate mutants modeling human bone diseases, and test new chemical compounds for the ability to revert bone defects. The zebrafish embryo develops rapidly, with precursors to all major organs appearing within 36 hours of fertilization. To encourage the fish to spawn, some researchers use a fish tank with a sliding bottom insert, which reduces the depth of the pool to simulate the shore of a river. , As the immune system is relatively conserved between zebrafish and humans, many human infectious diseases can be modeled in zebrafish.  The northern limit is in the South Himalayas, ranging from the Sutlej river basin in the Pakistan–India border region to the state of Arunachal Pradesh in northeast Indian. The zebrafish reference genome sequence of 1.4GB and over 26,000 protein coding genes was published by Kerstin Howe et al. Their enduring popularity can be attributed to their playful disposition, as well as their rapid breeding, aesthetics, cheap price and broad availability. A manuscript describing the cloning and expression of this novel gene is currently in review. We were also able to characterize a novel Gdf11 gene from zebrafish that has potential in regulating muscle growth. Purpose of review: Both traditional and novel cancer therapies can cause cardiovascular toxicity in patients. , Due to their fast and short life cycles and relatively large clutch sizes, D. rerio or zebrafish are a useful model for genetic studies. Human diseases caused by genes that do not exist in zebrafish require a different animal model. Other advantages include the species' nearly constant size during early development, which enables simple staining techniques to be used, and the fact that its two-celled embryo can be fused into a single cell to create a homozygous embryo. Because your research depends on it. We appreciate as much detail as possible and references as appropriate. A similarity was observed between zebrafish and mammalian responses, both in terms of effect direction and size. , Transgenesis is a popular approach to study the function of genes in zebrafish. Injected zebrafish were transferred to six-well plates, 30 zebrafish per well with 3 mL of fish water for a treatment period of 24 h. Zebrafish injected with 10 nL 0.9% sodium chloride served as vehicle controls and untreated zebrafish were used to confirm that the vehicle solvent did not have an adverse effect on the zebrafish. , then all zebrafish over 4.8 mm should have adipocytes and all fish 4.2 mm SL smaller!
