(Acta Scientiarum - Technology, 2022) [Artigo]The aim of this study was to explore the profile of bioactive compounds of Merlot grape pomace by different methodologies including phenolic composition by spectrophotometry, chromatography and spectroscopy and its ... -
Natural latex serum: characterization and biocompatibility assessment using Galleria mellonella as an alternative in vivo model
(Journal of Biomaterials Science, Polymer Edition, 2022) [Artigo]Natural latex serum (NLS) is one of the natural rubber latex fractions from Hevea brasiliensis tree, which is formed by centrifuged serum and is composed of proteins, acids, nucleotides, salts and carbohydrates. The proteins ... -
Local spatial distribution of stream macroalgae – does gastropod activity matters?
(Fundamental and Applied Limnology, 2021) [Artigo]The effects of gastropod Biomphalaria sp. on the benthic algae community (micro and macroalgae) were experimentally studied in an unshaded artificial stream. Using artificial substrates, two treatments were tested: with ... -
In vitro inhibition of acetylcholinesterase and monoamine oxidase by Syzygium cumini leaves extract and preliminary assessment in animal models
(South African Journal of Botany, 2022) [Artigo]Syzygium cumini (Myrtaceae) is a tropical tree used in traditional medicines to treat several diseases. All parts of S. cumini are used for medicinal purposes and present antioxidant potential. In this study, we evaluated ... -
Residual Starch Packaging Derived from Potato Washing Slurries to Preserve Fruits
(Food and Bioprocess Technology, 2021) [Artigo]Non-biodegradable petroleum-based plastics are still widely used by the food industry for packaging applications and, due to that bio-based raw materials such as starch, have been attracting growing interest from the ... -
Waterlogging as an environmental filter to tree recruitment in tropical wet grasslands
(Australian Journal of Botany, 2021) [Artigo]Wet grasslands from the Brazilian Savanna (Cerrado) are open-canopy vegetation dominated by subshrubs and herbaceous plants. Although they frequently occur between gallery forests and savannas, tree species are rarely ... -
3D printed-polylactic acid scaffolds coated with natural rubber latex for biomedical application
(Journal of Applied Polymer Science, 2022) [Artigo]Three-dimensional (3D) printing is a rapidly growing technology and plays an emerging role in several biomedical applications. Polylactic acid (PLA) is one of the most common materials in 3D printing, however, it is ... -
Effect of herbicides based on glyphosate on the photosynthesis of green macroalgae in tropical lotic environments
(Fundamental and Applied Limnology, 2021) [Artigo]The susceptibility of aquatic environments to contamination by glyphosate has been of worldwide con-cern, mainly since this herbicide affects important physiological processes such as photosynthesis. Considering this, we ... -
Human mesenchymal stem cells seeded on the natural membrane to neurospheres for cholinergic-like neurons
(Membranes, 2021) [Artigo]This study aimed to differentiate human mesenchymal stem cells (hMSCs) from the human umbilical cord in cholinergic-like neurons using a natural membrane. The isolation of hMSCs from Wharton’s jelly (WJ) was carried out ... -
Food Waste as a Feedstock for Fungal Biosynthesis of Amylases and Proteases
