A chronic toxicity bioassay was conducted with the microcrustacean Artemia salina as the testing organism for the toxic organophosphate diazinon in order to determine if the species is an appropriate indicator of pollution in aquatic environments. Tests of animal exposure to different concentrations of the toxicant were performed for 24, 48 and 72 hours after larvae hatching. Registered mortali...

Cyanobacteria are a diverse group of Gram-negative bacteria that produce an array of secondary compounds with selective bioactivity against vertebrates, invertebrates, plants, microalgae, fungi, bacteria, viruses and cell lines. The aim of this study was to assess the toxic effects of aqueous, methanolic and hexane crude extracts of benthic and picoplanktonic cyanobacteria isolated from estuari...

This article presents materials on the results of an experiment enrichment Artemia salina with unicellular alga Haematococcus pluvialis to increase its nutritional value. For fry marine fish, such as mullet and kalkana, freshwater clary catfish, carp trout, supply fatty acids energy value is still insufficient. Therefore, it necessary enrich brine shrimp additional nutrients The use a component...

Medicinal plants are a good source of therapeutic drugs because they contain phytochemical compounds. Cat's whiskers (Orthosiphon stamineus) and miana (Coleus artropurpureus) that widely used as herbal medicines. However, there no studies related to toxicology ensure its safety. The aim this study was determine the toxicity 96% ethanol extract cat leaves shrimp (Artemia salina Leach) larvae. To...

Daun Ekor Kucing (Acalypha hispida Burm.f.) merupakan jenis tanaman hias yang telah dikenal masyarakat Indonesia untuk pengobatan, namun belum ada penelitian meneliti toksisitas akut daun ekor kucing. Tanaman ini mengandung senyawa alkaloid dan flavonoid. Tujuan dari adalah mengetahui potensi ketoksikan ekstrak etanol kucing (A. terhadap larva Artemia salina Leach dengan metode Brine Shrimp Let...

Iron metallodrugs comprise mineral supplements, anti-hypertensive agents and, more recently, magnetic nanomaterials, with both therapeutic and diagnostic roles. As biologically-active metal compounds, concern has been raised regarding the impact of these compounds when emitted to the environment and associated ecotoxicological effects for the fauna. In this work we assessed the relative stabili...

A protein that binds tightly to single-stranded but not to double-strained nucleic acids has been purified to homogeneity from a high salt wash of ribosomes from cryptobiotic Artemia salina gastrulae. The protein, designated HD40 to indicate a helix-destabilizing protein with a molecular weight of 40,000, is present in the high-salt ribosomal wash at a level of about 2 molecules per 80 S riboso...
