Abstract Carbendazim is a fungicide largely used in agriculture as plant protection product. As result of agricultural runoffs, drainage, and leaching, it reaches surface waters at concentrations possibly hazardous to aquatic communities. Because potential continuous release carbendazim systems, long‐term exposure organisms should be addressed. To fill the knowledge gap, present study evaluated responses multiple generations Daphnia magna (clone K6) an environmentally relevant concentration...
Introdução: Nas últimas décadas, apesar dos esforços do Ministério da Saúde para ampliar o acesso a programas de rastreio e monitoramento qualidade exames citopatológicos, as taxas morbimortalidade câncer cervical no Brasil permaneceram altas. A persistência desses índices sugere falhas nos programas, provavelmente em virtude baixa cobertura populacional, acompanhamento erros processo coleta interpretação exames. Para melhorar prevenção Espírito Santo, Unidade Monitoramento Externo Qualidade...
New copper complexes with an impressive DNA cleaving ability in the absence of any exogenous oxidants or reductants.
Strain NL19T is a Gram-stain-negative, aerobic bacterium that was isolated from sludge of deactivated uranium mine in Portugal. 16S rRNA gene sequence analysis revealed strain member the genus Pedobacter and closely related to strains himalayensis MTCC 6384T, cryoconitis DSM 14825T, westerhofensis 19036T Pedobacterhartonius 19033T. It had DNA G+C content 40.8 mol%, which agreed with description. The main fatty acids included C16 : 1ω7c, C14 1ω5c, C4 0, iso-C17 0 3-OH, anteiso-C15 iso-C15...
Abstract The effect of tributyltin (TBT) on growth and metabolic activity three estuarine bacteria with different TBT resistance profiles was investigated in an organic‐rich culture medium (TSB) phosphate buffered saline (PBS) buffer. Exposure to assessed by determining its (OD 600 nm measurement), bacterial productivity (leucine incorporation), viability (CFU counts), aggregation cell size (from Live/Dead analysis), ATP NADH concentrations. exposure resulted decrease density, size,...
The mechanism of bacterial resistance to tributyltin (TBT) is still unclear. results herein presented contribute clarify that in the TBT-resistant bacterium Aeromonas molluscorum Av27. We have identified and cloned a new gene involved TBT this strain. highly homologous (84%) hydrophila-sugE belonging small multidrug family (SMR), which includes genes transport lipophilic drugs. In Av27, expression Av27-sugE was observed at early logarithmic growth phase presence high concentration (500 μM),...
Abstract Anthropogenic activities such as the use of pesticides may affect aquatic biota populations, due to potential agricultural runoffs or disposals. Carbendazim is one example a widely used fungicide with high end up in ecosystems through runoff. Deleterious effects observed at individual level are possibly explained by changes homeostasis cellular level, and both factors can then be predict population level. In present study, an isoclonal Daphnia magna (clone K6) was exposed...
The present study shows the comet assay technique being successfully applied for first time to one of most widely used soil organisms in standardized ecotoxicological tests, Folsomia candida, providing a step forward assessing genotoxicity induced by xenobiotics. Because collembolans have high content chitin, new methodology was developed which heads were separated from rest body, allowing hemolymph leak out. This procedure allows cells be released, and after lysis genetic material is...
The two layer system AlyGa1−yAs on GaAs is studied in the range (0⩽y≲1). open photoacoustic cell technique used to obtain thermal diffusivity, conductivity, heat capacity, and expansion coefficient. It shown that properties of individual layers can be determined using low modulation frequency regime models without actually separating system. possibilities advantages approach for characterization layered semiconductor systems are discussed.
Aeromonas molluscorum Av27 cells were exposed to 0, 5 and 50 μM of TBT the respective transcriptomes obtained by pyrosequencing. Gene Ontology revealed that exposure results in a higher number repressed genes contrast with TBT, where over-expressed is greater. At both concentrations, variations gene expression found functional categories associated enzymatic activities, transport/binding oxidation-reduction. A proteins are affected such as acriflavin resistance protein, several...
In the last decades, wildlife–human interface has been increasing due to several anthropogenic factors. Therefore, it is crucial be aware of impact these new dynamics on health wild animals and their associated zoonotic disease risks. This study aimed characterize faecal microbiota two populations red deer (Cervus elaphus) by metabarcoding, with a particular focus potential human veterinary pathogens, perform an assessment antibiotic resistance genes (ARGs) occurrence. The was assessed...
Er-doped lithium niobate (LiNbO3) ceramics embedded in silica were grown by the sol–gel method. The dried gel 91SiO2–4Li2O–4Nb2O5–Er2O3 (mol%) was subsequently heat treated between 500 and 750 °C. X-ray diffraction Raman spectroscopy have detected crystallization of LiNbO3 ErNbO4 samples at temperatures above 600 At least two Er-related optical centres been identified low-temperature absorption photoluminescence studies. dominant intra-ionic transition arises from Er3+ ion, C2v site...
