Metabolic downregulation during diapause in embryos of Artemia franciscana
Encysted embryos of <i>Artemia franciscana</i> undergo a dramatic respiratory depression upon release from the adult female as they enter a state of hypometabolism termed diapause. The mechanisms by which such a respiratory depression is achieved remain unexplained. Evidence presented here shows …

Biostabilization of Lipid Bilayers: Dealing with Water Stress in Embryos of Artemia franciscana
… water stress by protectants found in embryos of Artemia franciscana. Two LEA proteins were used: AfrLEA2 and AfrLEA3m. AfrLEA3m was experimentally demonstrated to reside in the matrix. Two detergents were used to differentially solubilize the outer and inner membranes of mitochondria isolated …

Aluminium toxicity (with reference to Copper) in the aqueous environment and the mechanisms of its glutathione-mediated detoxification in the brine shrimp (Artemia franciscana)
… happened to two test species (the brine shrimp Artemiafranciscana and the bacterium Vibrio fischerii), and, in the case of Al, a field study entailing chemical and biological monitoring. In addition, studies were undertaken which showed that Al bioaccumulates in A. franciscana (which is farmed …

Characterization of cellular stress systems using biological mass spectrometry
… protein purified from the encysted embryo of Artemia franciscana was characterized by time-of-flight mass spectrometry. De novo sequencing of peptides identified this protein as a group 1 Late embryogenesis abundant (LEA) protein. The amino acid sequence assignment to these peptides allowed …

Metabolism and gene expression during diapause in athropods
… unexplained. Aerobic metabolism in diapause, Artemia franciscana, embryos is reduced up to 92 % compared with post-diapause embryos. Differences in isolated mitochondria are insufficient to account for respiratory depression because mitochondria in diapause embryos are structurally similar to …

Quroum sensing disruption and the use of short-chain fatty acids and polyhydroxyalkanoates to control luminescent vibriosis
… Vibrio harveyi towards gnotobiotic brine shrimp (Artemia franciscana) nauplii. Subsequently, halogenated furanones were shown to disrupt quorum sensing in these bacteria by decreasing the DNA-binding activity of the quorum sensing master regulator protein LuxR. Interestingly, the addition of 20 mg …

Factors Affecting Recruitment of Black Crappies in South Dakota Waters
… (218 NTU). The feeding regime was newly hatched Artemia franciscana provided once daily for 38 d. No juvenile black crappies survived in the low turbidity tanks after 33 d. Survival was highest (mean = 99%) for fish held in no turbidity and moderate for fish held in both medium and high …
