Metabolic and oxidative impairments in human salivary gland cells line exposed to MeHg
(Elsevier, 2021)Background/aim: The ingestion of contaminated seafood by MeHg is considered the main route of human exposure, turning the salivary gland one important target organ. The salivary glands play critical roles in maintaining ... -
Evaluation of the contamination of the soil and water of an open dump in the Amazon Region, Brazil
(Springer, 2021)The emergence of cities and the ongoing growth of urban areas have contributed to an overwhelming increase in negative environmental impacts. A major concern is the impact caused by the inadequate disposal of municipal ... -
The influence of some axial ligands on Ruthenium–Phthalocyanine complexes: chemical, photochemical, and photobiological properties
(Frontiers Media, 2021)This work presents a new procedure to synthesize ruthenium–phthalocyanine complexes and uses diverse spectroscopic techniques to characterize trans-[RuCl(Pc)DMSO] (I) (Pc = phthalocyanine) and trans-[Ru(Pc)(4-ampy)2] (II) ... -
Genomic and transcriptomic characterization of the human glioblastoma cell line AHOL1
(Associação Brasileira de Divulgação Científica, 2021)Cancer cell lines are widely used as in vitro models of tumorigenesis, facilitating fundamental discoveries in cancer biology and translational medicine. Currently, there are few options for glioblastoma (GBM) treatment ... -
The role of the chromosomal rearrangements in the evolution and speciation of Elopiformes fishes (Teleostei; Elopomorpha)
(Elsevier, 2021)Elopiformes is one of the most ancient orders of Teleostei fishes and includes the Megalopidae and Elopidae families. Although relevant to scientific research, cytogenetic and molecular data are lacking for both families. ... -
The consumption of shark meat in the Amazon region and its implications for human health and the marine ecosystem
(Elsevier, 2021)Here, we evaluated the levels of As, Hg, Pb, and Cd in shark meat sold along the Amazon Coast of Brazil and used nitrogen stable isotope values to determine trophic position and to assess element biomagnification. From ... -
Imaging microstructural damage and alveolar bone loss in rats systemically exposed to methylmercury: first experimental evidence
(Springer Verlag, 2021)The alveolar bone is an important mineralized structure of the periodontal support apparatus, and information about the methylmercury (MeHg) effects on the structural integrity is scarce. Therefore, this study aimed to ... -
Fluoride exposure during pregnancy and lactation triggers oxidative stress and molecular changes in hippocampus of offspring rats
(Elsevier, 2021)Long-term exposure to high concentrations of fluoride (F) can damage mineralized and soft tissues such as bones, liver, kidney, intestine, and nervous system of adult rats. The high permeability of the blood–brain barrier ... -
Extensive chromosomal fissions and repetitive DNA accumulation shaped the atypical karyotypes of two Ramphastidae (Aves: Piciformes) species
(Oxford University Press, 2020)In contrast to the ‘avian-like’ diploid number (2n = 80), most toucans and aracaris (Piciformes: Ramphastidae) have divergent karyotypes, exhibiting a higher 2n. To identify the chromosomal rearrangements that shaped the ... -
Application of the quartz crystal microbalance method for measuring mercury in the air of working environments involved to artisanal and small-scale gold mining (ASGM)
(Nihon Bunseki Kagakkai, 2020)Artisanal small gold mining (ASGM) is responsible for approximately 40% of the total Hg emissions into the atmosphere worldwide. In developing countries, many people are engaged in ASGM activities. We developed a small, ... -
Layered double hydroxide–indomethacin hybrid: A promising biocompatible compound for the treatment of neuroinflammatory diseases
(Elsevier, 2020)Indomethacin (INDO) demonstrates therapeutic efficacy in the treatment of neuroinflammatory diseases. Despite its importance as a drug, INDO causes gastrointestinal problems and adverse reactions in the central nervous ... -
Comparative chromosome painting in hummingbirds (Trochilidae)
(Sociedade Brasileira de Genética, 2020)Hummingbirds (Trochilidae) are one of the most enigmatic avian groups, and also among the most diverse, with approximately 360 recognized species in 106 genera, of which 43 are monotypic. This fact has generated considerable ... -
Chromosomal analysis in Crotophaga ani (Aves, Cuculiformes) reveals extensive genomic reorganization and an unusual Z-autosome robertsonian translocation
(Elsevier, 2021)Abstract: Although cytogenetics studies in cuckoos (Aves, Cuculiformes) have demonstrated an interesting karyotype variation, such as variations in the chromosome morphology and diploid number, their chromosome organization ... -
Comparative cytogenetic survey of the giant bonytongue arapaima fish (Osteoglossiformes: Arapaimidae), across different Amazonian and Tocantins/Araguaia River Basins
(Sociedade Brasileira de Ictiologia, 2020)The South American giant fishes of the genus Arapaima, commonly known as pirarucu, are one of the most iconic among Osteoglossiformes. Previously cytogenetic studies have identified their karyotype characteristics; however, ... -
Novel chalcones derivatives with potential antineoplastic activity investigated by docking and molecular dynamics simulations
