Intraperitoneal Exposure to Nano/Microparticles of Fullerene (C60) Increases Acetylcholinesterase Activity and Lipid Peroxidation in Adult Zebrafish (Danio rerio) Brain

BioMed Research International, Volume 2013, Issue 1, 2013., 2013
Even though technologies involving nano/microparticles have great potential, it is crucial to determine possible toxicity of these technological products before extensive use. Fullerenes C60 are nanomaterials with unique physicochemical and biological properties that are important for the development of many technological applications.

Acute Exposure to Microcystin‐Producing Cyanobacterium Microcystis aeruginosa Alters Adult Zebrafish (Danio rerio) Swimming Performance Parameters

Journal of Toxicology, Volume 2011, Issue 1, 2011., 2011
Microcystins (MCs) are toxins produced by cyanobacteria (blue‐green algae), primarily Microcystis aeruginosa, forming water blooms worldwide. When an organism is exposed to environmental perturbations, alterations in normal behavioral patterns occur.

Modulation of Sleep Homeostasis by Corticotropin Releasing Hormone in REM Sleep‐Deprived Rats

International Journal of Endocrinology, Volume 2010, Issue 1, 2010., 2010
Studies have shown that sleep recovery following different protocols of forced waking varies according to the level of stress inherent to each method. Sleep deprivation activates the hypothalamic‐pituitary‐adrenal axis and increased corticotropin‐releasing hormone (CRH) impairs sleep.
