Effects of alpha particles on zebrafish embryos.
Dechorionated zebrafish embryos were irradiated at 1.5 h post fertilization (hpf) to low-doses of alpha particles, viz., 1.4, 2.8, 5.6, 11.2 mGy (determined using Monte Carlo simulations). At 24 hpf, these embryos were then examined for apoptotic cells through acridine orange staining. The mean number of apoptotic cells was found to decrease significantly from controls to 1.4-mGy irradiation, a...
متن کاملInfection of Zebrafish Embryos with Intracellular Bacterial Pathogens
Zebrafish (Danio rerio) embryos are increasingly used as a model for studying the function of the vertebrate innate immune system in host-pathogen interactions. The major cell types of the innate immune system, macrophages and neutrophils, develop during the first days of embryogenesis prior to the maturation of lymphocytes that are required for adaptive immune responses. The ease of obtaining ...
متن کاملosteoclast-like cells in early zebrafish embryos
objective: genes involved in bone and tissue remodelling in the vertebrates include matrix metalloproteinase-9 (mmp-9), receptor activator of necrosis factor κ-β (rank), cathepsin-k (ctsk) and tartrate-resistant acid phosphatase (tracp). we examine whether these markers are expressed in cells of zebrafish embryos of 1-5 days post fertilization. we also examine adult scales, which are known to c...
متن کاملBacterial toxins.
Many bacterial toxins are proteins, encoded by the bacterial chromosomal genes, plasmids or phages. Lysogenic phages form part of the chromosome. The toxins are usually liberated from the organism by lysis, but some are shed with outer membrane proteins in outer membrane vesicles. An important non-protein toxin is lipopolysaccharide or endotoxin, which is a constituent of the cell wall of gram ...
متن کاملAlpha-particle-induced bystander effects between zebrafish embryos in vivo
Dechorionaed embryos of the zebrafish, Danio rerio, at 1.5 h post-fertilization (hpf) were irradiated with alpha particles from an 241Am source. Thin polyallyldiglycol carbonate (PADC) films with a thickness of 16 mm were used as support substrates for holding the embryos and recorded alpha-particle hit positions, and thus enabled calculation of the dose absorbed by the embryos. The irradiated ...
