Acute effects of a prooxidant herbicide on the microalga Chlamydomonas reinhardtii: Screening cytotoxicity and genotoxicity endpoints
(Elsevier, 2015-08)Since recent evidence has demonstrated that many types of chemicals exhibit oxidative and/or genotoxic potential on living organisms, reactive oxygen species (ROS) formation and DNA damage are currently the best accepted ... -
Cell proliferation alterations in Chlorella cells under stress conditions
(2009-09)[Abstract]Very little is known about growth and proliferation in relation to the cell cycle regulation of algae. The lack of knowledge is even greater when referring to the potential toxic effects of pollutants on microalgal ... -
Characterization of cell response in Chlamydomonas moewusiicultures exposed to the herbicide paraquat: Induction of chlorosis
(2011-03)[Abstract] The use of herbicides constitutes the principal method of weed control, but the introduction of these compounds into the aquatic environment can provoke severe consequences for non-target organisms such as ... -
Chlamydomonas Reinhardtii Cells Adjust the Metabolism to Maintain Viability in Response to Atrazine Stress
(Elsevier, 2015-05-19)[Abstract] Chlamydomonas reinhardtii cells were exposed to a sublethal concentration of the widespread herbicide atrazine for 3 and 24 h. Physiological parameters related to cellular energy status, such as cellular ... -
Copper toxicity on the marine microalga Phaeodactylum tricornutum: effects on photosynthesis and related parameters
(Elsevier, 1995-02)Essential heavy metals, as copper, can be toxic for microalgae at high concentrations. Copper affected growth and other parameters closely related to photosynthesis of the marine diatom Phaeodactylum tricornutum. A copper ... -
Cytotoxicity of BP-3 and BP-4: Blockage of Extrusion Pumps, Oxidative Damage and Programmed Cell Death on Chlamydomonas reinhardtii
(Elsevier, 2022-09-07)[Abstract] The health concern associated with the dangers related to exposure to UV radiation has led to an increase in the use of sunscreens containing UV-filters that can reach aquatic environments and possibly affect ... -
Early alterations on photosynthesis-related parameters in Chlamydomonas reinhardtii cells exposed to atrazine: A multiple approach study
(Elsevier, 2016-06-01)Chlamydomonas reinhardtii cells were exposed to a sublethal concentration of thewidespread herbicide atrazine for 3 h. Physiological cellular parameters, such as chlorophyll a fluorescence and oxidative stress monitored ... -
Flow cytometric analysis of the encystment process induced by paraquat exposure in Haematococcus pluvialis (Chlorophyceae)
(Taylor & Francis, 2011)The freshwater microalga Haematococcus pluvialis exhibits a unique morphological response to environmental stress, accumulating carotenoid pigment during encystment. The complexity of characterizing the different cell ... -
Flow cytometric analysis to evaluate physiological alterations in herbicide-exposed Chlamydomonas moewusii cells
(Springer, 2012-03)Investigation of herbicide toxicology in non-target aquatic primary producers such as microalgae is of great importance from an ecological point of view. In order to study the toxicity of the widely used herbicide paraquat ... -
Flow cytometric assay to assess short-term effects of personal care products on the marine microalga Tetraselmis suecica
(Elsevier, 2017)[Abstract] Large quantities of personal care products (PCPs) are used daily and many of their chemical ingredients are subsequently released into marine environments. Cultures of the marine microalga Tetraselmis suecica ... -
Potential use of flow cytometry in toxicity studies with microalgae
(2000-03)[Abstract]Cytotoxic effects of aquatic pollutants on microalgae are very heterogeneous, and they are influenced by environmental conditions and the test species. Stress produced by copper or paraquat addition to the culture ... -
Screening acute cytotoxicity biomarkers using a microalga as test organism
(Elsevier, 2012-12)The present study checked the suitability of the integration of flow cytometry (FCM) as technique and a freshwater microalga (Chlamydomonas moewusii) as cell system model for ecotoxicological studies, looking for sensitive ... -
Suitability of cytotoxicity endpoints and test microalgal species to disclose the toxic effect of common aquatic pollutants
(Elsevier, 2015-04)Pulse discharges of chemicals to aquatic environments may lead to high concentrations of them in surface waters for short periods of time, but enough to induce toxic effects on aquatic organisms; however, no many methods ... -
Toxic action of copper on the membrane system of a marine diatom measured by flow cytometry
(WILEY-Liss, 1996-09)Flow cytometric measurements were used to investigate the toxic action of copper on some Phaeodactylum tricornutum membrane systems. Throughout the time of metal exposure, the percentage of viable cells decreased as copper ... -
Unravelling Joint Cytotoxicity of Ibuprofen and Oxytetracycline on Chlamydomonas Reinhardtii Using a Programmed Cell Death-Related Biomarkers Panel
(Elsevier, 2023-02-24)[Abstract] Pharmaceutical active compounds (PhACs) are emerging contaminants that pose a growing concern due to their ubiquitous presence and harmful impact on aquatic ecosystems. Among PhACs, the anti-inflammatory ibuprofen ...
