Cytotoxic effect of some furanosesquiterpenes from balsamodendron myrrha nees. oleo-gum-resin on brine shrimp (artemia salina) larvae ayesha asif1,

A gynandromorph of the brine shrimp, Artemia salina.

S EXUAL mosaics have been reported in three genera of Crustacea. A bilateral mosaic of Carcinus was found to have a testis on one side and a mixed gonad on the other (VEILLET 1945). Gynandromorphs with a testis and ovary have been reported in Homarus (see review by CHACE and MOORE 1959) and in the cladoceran, Simocephalus (BANTA, WOOD, BROWN and INGLE 1939). No intersex or mosaic of Artemia has...

Toxicity Testing of Restorative Dental Materials Using Brine Shrimp Larvae (artemia Salina)

This study investigated the effect of extracts of different composites, glass ionomer cement (GIC)s and compomers on the viability of brine shrimp larvae. Ethanolic extracts of four dental composites (Z-100; Solitaire 2; Filtek P60 and Synergy), a conventional GIC (Ketac-Fil), a resin-modified glass ionomer cement (Vitremer), two compomers (F2000; Dyract AP), and a flowable compomer (Dyract Flo...

A MODIFIED MICROPLATE CYTOTOXICITY ASSAY WITH BRINE SHRIMP LARVAE (Artemia salina)

Artemia salina nauplii are widely used in toxicity assays of synthetic and natural products. Microassays are particularly useful because they allow testing of several products, serially diluted, in a sole microplate. Despite this, following the original method, we have observed systematically about 30% mortality in nontreated controls. Thus, we introduced several modifications that improved the...

An Evaluation of the Antimicrobial Activity of Commiphora myrrha Nees (Engl.) Oleo-gum Resins from Saudi Arabia

Toxicity of benthic dinoflagellates on grazing, behavior and survival of the brine shrimp Artemia salina

Harmful algae may differently affect their primary grazers, causing sub-lethal effects and/or leading to their death. The present study aim to compare the effects of three toxic benthic dinoflagellates on clearance and grazing rates, behavioral changes, and survival of Artemia salina. Feeding assays consisted in 1-h incubations of brine shrimps with the toxic Prorocentrum lima, Gambierdiscus ex...
