Artemia is one of the most important test organisms available for ecotoxicity test. In this study the toxicity of five widely used herbicides formulations including: Paraquat, 2,4-dichlorophenoxy acetic acid (2,4-D), Trifluralin, Glyphosite and Atrazin were compared using ecotoxicity bioindicator, Artemia franciscana. Acute toxicity (48 h LC50) of five herbicides were determined via OECD standa...

In a biogeographical context, the term Macaronesia broadly embraces the North Atlantic archipelagos of the Azores, Madeira, Selvagens, the Canary Islands, and Cape Verde. The peculiar arid climatic conditions in some of these places have led to the development of marine salt exploitations, which can be counted among the hypersaline habitats of the brine shrimp Artemia (Branchiopoda, Anostraca)....

Background Biomineralization, e.g., in sea urchins or mollusks, includes the assembly of mesoscopic superstructures from inorganic crystalline components and biopolymers. The resulting mesocrystals inspire biophysicists and material scientists alike, because of their extraordinary physical properties. Current efforts to replicate mesocrystal synthesis in vitro require understanding the principl...

This study reports on the acute toxic effects of Aloe barbadensis Miller (Aloe vera) juice as well as high doses of the antioxidants vitamin C, vitamin E and TroloxTM (a water soluble vitamin E analogue) to the salt water crustacean Artemia franciscana. Aloe vera juice exposure resulted in acute toxicity, being capable of inducing mortality at dilutions as low as 4 % juice and having an LC50 at...

When mammalian mitochondria are exposed to high calcium and phosphate, a massive swelling, uncoupling of respiration, and release of cytochrome c occur. These changes are mediated by opening of the mitochondrial permeability transition pore (MPTP). Activation of the MPTP in vivo in response to hypoxic and oxidative stress leads to necrotic and apoptotic cell death. Considering that embryos of t...

The movement of small animals in well-defined environments is increasingly used in ecotoxicology as a sensitive indicator of water contamination with toxicants. This work describes a framework for the analysis of Artermia franciscana within miniaturised chambers. This work combines: (a) a proof-ofconcept miniaturised Lab-on-a-Chip (LOC) platform where any changes in swimming patterns exhibited ...

This study was undertaken to evaluate the protective efficacy of the antioxidants vitamin E and Trolox (a water-soluble vitamin E derivative) against the toxicity of microcystin-LR (MC-LR), Microcystis aeruginosa aqueous extract (CE), and a reference toxin, menadione sodium bisulfite (MSB), in Artemia franciscana nauplii. This was achieved by using the well-established brine shrimp bioassay. Th...
