Ecotoxicity Evaluation of the Biodegradable Polymers PLA, PBAT and its Blends Using Allium cepa as Test Organism
(2018-03-01)
Biodegradable polymers are considered a feasible option to minimize the environment impacts of high disposal of solid waste. Nevertheless, environmental safety of these materials is a few explored issue. In this context, ...
Detection of Toxoplasma gondii in the milk of experimentally infected wistar female rats
(2010-01-01)
The milk of experimentally infected rats was investigated for the presence and possible transmission of Toxoplasma gondii. Wistar (Rattus norvegicus) female rats were divided into three groups and orally inoculated with ...
Transplant bioassay induces different imposex responses in two species of the genus Stramonita
(Taylor & Francis, 2012-02-14)
A bioassay to study differential specific responses in imposex development due to marine organotin pollution was done by transplanting specimens of the gastropods Stramonita haemastoma and Stramonita rustica from an ...
N-Acetylated Gemini Surfactants: Synthesis, Surface-Active Properties, Antifungal Activity, and Ecotoxicity Bioassays
(Scientific Research Publishing, 2015-05)
A series of N-acetylated cationic gemini surfactants (3a-e) having dimeric structures derived from tertiary amines were synthesized. Their antifungal potency and surface properties were determined. It also studied the acute ...
Trypanocidal Activity of Smallanthus sonchifolius. Identification of Active Sesquiterpene Lactones by Bioassay-Guided Fractionation.
(Oxford University Press, 2013-06)
In order to find novel plant-derived biologically active compounds against Trypanosoma cruzi, we isolated, from the organic extract of Smallanthus sonchifolius, the sesquiterpene lactones enhydrin (1), uvedalin (2), and ...
Pathogenicity of Metarhizium anisopliae towards Rhipicephalus (Boophilus) microplus under laboratory and field conditions
(ACADEMIC JOURNALSVICTORIA ISLAND, 2012)
Metarhizium anisopliae is one of the most studied agents of biological control of several arthropod plagues, including the cattle tick Rhipicephalus (Boophilus) microplus. Studies have been conducted to assess the fungal ...
Biomonitoring genotoxic risks under the urban weather conditions and polluted atmosphere in Santo Andre, SP, Brazil, through Trad-MCN bioassay
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2009)
The present study was made to check if the Trad-MCN bioassay, developed with inflorescences of Tradescantia pallida cv. Purpurea, might discriminate genotoxic risks in areas of the city of Santo Andre (SE Brazil) contaminated ...
