(2021) [Artigo de periódico]Background: Mucopolysaccharidosis II (MPS II; Hunter syndrome) is a rare, life-limiting lysosomal storage disease caused by defcient iduronate-2-sulfatase activity. Enzyme replacement therapy (ERT) with intravenous (IV) ... -
Evaluation of the physicochemical and antibacterial properties of experimental adhesives doped with lithium niobate
(2020) [Artigo de periódico]The aim of the present study was to formulate dental adhesives with different concentrations of LiNbO3 and to evaluate their physicochemical and antibacterial properties. A dental adhesive was formulated using methacrylate ... -
Evaluation of total protein, peroxidase, and nutrients measured by pXRF for the determination of tissue rejuvenation / reinvigoration of Eucalyptus microcorys
(2023) [Artigo de periódico]Ontogenetic aging of tissues and the gradual decrease of adventitious rooting are known challenges for the clonal propagation of woody species, hampering clonal forestry programs. This study examined possible signatures ... -
Evaluation of toxicological effects of an aqueous extract of shells from the pecan nut Carya illinoinensis (Wangenh.) K. Koch and the possible association with its inorganic constituents and major phenolic compounds
(2016) [Artigo de periódico]Background. Industrial processing of the pecan nut Carya illinoinensis K. Koch generated a large amount of shells, which have been used to prepare nutritional supplements and medicinal products; however, the safe use of ... -
Evaluation of trace metals (cadmium, chromium, copper and zinc) in tissues of a commercially important fish (Leporinus obtusidens) from Guaíba Lake, Southern Brazil
(2009) [Artigo de periódico]As concentrações dos metais Cd, Cr, Cu e Zn foram determinadas para os tecidos muscular e hepático de Leporinus obtusidens no sul do Brasil. Durante o ano de 2003, 54 indivíduos foram capturados em três locais ao longo do ... -
Evaluation of two Brazilian indigenous plants for phytostabilization and phytoremediation of copper-contaminated soils
(2015) [Artigo de periódico]Indigenous plants have been grown naturally and vigorously in copper contaminated soils. Thus, the aim of this study was to evaluate the phytoremediation ability of two indigenous plants naturally grown in two vineyard ... -
Evaporação da água na superficie do solo em sistemas de plantio direto e preparo convencional
(2010) [Artigo de periódico]Este trabalho teve por objetivos quantificar a evaporação da água na superfície do solo, em plantio direto e em preparo convencional, e avaliar o uso de microlisímetros de pesagem para medir esse processo. As medições foram ... -
Evidence of niche partitioning under ontogenetic influences among three morphologically similar siluriformes in small subtropical streams
(2014) [Artigo de periódico]Ontogenetic influences in patterns of niche breadth and feeding overlap were investigated in three species of Siluriformes (Heptapterus sp., Rhamdia quelen and Trichomycterus poikilos) aiming at understanding the species ... -
Evidence of vertical migration in the Ipanema bat Pygoderma bilabiatum (Chiroptera: Phyllostomidae: Stenodermatinase)
(2011) [Artigo de periódico]Migration is defined as a seasonal and cyclic population movement observed in all animal classes and studied mainly in vertebrates. A considerable part of the knowledge on migration comes from birds, for which migration ... -
Evolution and diversification of the O-methyltransferase (OMT) gene family in Solanaceae
(2023) [Artigo de periódico]O-methyltransferases (OMTs) are a group of enzymes involved in several fundamental biological processes in plants, including lignin biosynthesis, pigmentation, and aroma production. Despite the intensive investigation of ... -
