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 ... -
Assessment of cytotoxicity biomarkers on the microalga "Chlamydomonas reinhardtii" exposed to emerging and priority pollutants
(Elsevier, 2020-11-17)[Abstract] Contamination of aquatic ecosystems linked to anthropogenic activity is currently a major concern; therefore, ecotoxicological studies are needed to assess its effect on organisms. The main objective of this ... -
Assessment of Okadaic Acid Effects on Cytotoxicity, DNA Damage and DNA Repair in Human Cells
(Elsevier, 2010-05-26)[Abstract] Okadaic acid (OA) is a phycotoxin produced by several types of dinoflagellates causing diarrheic shellfish poisoning (DSP) in humans. Symptoms induced by DSP toxins are mainly gastrointestinal, but the intoxication ... -
Carbon nanotubes’ effect on mitochondrial oxygen flux dynamics: polarography experimental study and machine learning models using star graph trace invariants of Raman spectra
(MDPI, 2017-11-11)[Abstract] This study presents the impact of carbon nanotubes (CNTs) on mitochondrial oxygen mass flux (Jm) under three experimental conditions. New experimental results and a new methodology are reported for the first ... -

(M D P I AG, 2017-11-11)[Abstract] This study presents the impact of carbon nanotubes (CNTs) on mitochondrial oxygen mass flux (Jm) under three experimental conditions. New experimental results and a new methodology are reported for the first ... -
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 ... -
Comparative Study on Effects of Two Different Types of Titanium Dioxide Nanoparticles on Human Neuronal Cells
(Elsevier, 2013-04-15)[Abstract] Titanium dioxide (TiO2) are among most frequently used nanoparticles (NPs). They are present in a variety of consumer products, including food industry in which they are employed as an additive. The potential ... -
Cytotoxic furanoditerpenes from the sponge Spongia tubulifera collected in the Mexican Caribbean
(MDPI, 2019-07-16)[Abstract] Two new spongian furanoditerpenes, 3β-hydroxyspongia-13(16),14-dien-2-one (1) and 19-dehydroxy-spongian diterpene 17 (2), along with five known terpenes, the spongian furanoditerpenes 9-nor-3-hydroxyspongia-3, ... -
Early Genotoxic and Cytotoxic Effects of the Toxic Dinoflagellate Prorocentrum lima in the Mussel Mytilus galloprovincialis
(Multidisciplinary Digital Publishing Institute, 2016)Okadaic acid (OA) and dinophysistoxins (DTXs) are the main toxins responsible for diarrhetic shellfish poisoning (DSP) intoxications during harmful algal blooms (HABs). Although the genotoxic and cytotoxic responses to OA ... -
Effects of Zinc Oxide Nanoparticle Exposure on Human Glial Cells and Zebrafish Embryos
(MDPI, 2023-08-01)[Abstract] Zinc oxide nanoparticles (ZnO NPs) are among the most widely used nanomaterials. They have multiple applications in cosmetics, textiles, paints, electronics and, recently, also in biomedicine. This extensive use ... -
Evaluation of the in Vitro and in Vivo Efficacy of Ruthenium Polypyridyl Compounds Against Breast Cancer
(MDPI, 2021-08-18)[Abstract] The clinical success of cisplatin, carboplatin, and oxaliplatin has sparked the interest of medicinal inorganic chemistry to synthesize and study compounds with non-platinum metal centers. Despite Ru(II)–polypyridyl ... -
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 ... -
Neuronal Cytotoxicity and Genotoxicity Induced by Zinc Oxide Nanoparticles
(Elsevier, 2013-03-26)[Abstract] Zinc oxide nanoparticles (ZnO NPs) are one of the most abundantly used nanomaterials in consumer products and biomedical applications. As a result, human exposure to these NPs is highly frequent and they have ... -
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 ...
