1. A systematic review and meta-analysis of observational studies on the effects of epigenetic factors on serum triglycerides
ABSTRACT Epigenetic modifications might be associated with serum triglycerides (TG) levels. This study aims to systematically review the studies on the relationship between the methylation of specific cytosine-phosphate-guanine (CpG) sites and serum TG levels. This systematic review and meta-analysis study was conducted according to the PRISMA 2020 (Preferre

2. Niche differentiation between a native and an invasive species of submersed macrophyte in a subtropical reservoir
ABSTRACT Submersed macrophytes have important ecological roles but non-native invasive species may affect biodiversity and water uses. We investigated the native macrophyte Egeria najas and the invasive Hydrilla verticillata and measured their maximum colonization depth and its relationship with Secchi disk depth, their biomass along the depth gradient and t

3. Relationship between phytoplankton structure and environmental variables in tropical reservoirs with different trophic states
ABSTRACT Phytoplankton structure is influenced by environmental factors, seasonal cycles and the trophic state of the system. The objective of the present study was to identify guilds of phytoplankton species that are representative of seasonality and trophic status. We evaluated phytoplankton biomass and species composition in five tropical reservoirs, with

4. RNA editing in the chloroplast of Asian Palmyra palm (Borassus flabellifer)
Abstract We have identified 46 RNA editing sites located in 20 chloroplast (cp) genes of Borassus flabellifer (Asian Palmyra palm), family Arecaceae, and tested these genes for supporting phylogenetic study among the commelinids. Among the 46 sites, 43 sites were found to cause amino acid alterations, which were predicted to increase the hydrophobicity and t

5. The effect of encapsulants on the heat of sorption in vacuum-dried cajá powder
RESUMO Dados de umidade de equilíbrio do pó da poupa de cajá (PC) (Spondias mombin, L.) com e sem aditivos - 58% de maltodextrina (MD) ou 58% de goma arábica (GA) - foram determinadas em 20; 30; 40 e 50 °C, utilizando o método gravimétrico estática numa faixa de atividade de água de 0,06 a 0,90. As isotermas obtidas foram sigmóide, típica tipo III

6. Mulheres Indígenas nas Missões: patrimônio silenciado
Resumo: Ao problematizar o patrimônio histórico das Missões Indígenas-Jesuíticas (1609-1750) a partir de preocupações teórico-metodológicas relacionadas aos estudos de gênero e patrimônio, este artigo discute: a) representações sobre mulheres indígenas presentes na documentação histórica gerada pelos jesuítas; b) ressignificação dos espa�

7. Does traumatic occlusal forces lead to peri-implant bone loss? A systematic review
Abstract Observational studies have indicated that crestal bone level changes at implants are typically associated with clinical signs of inflammation, but still mechanical overload has been described as possible factor leading to hard–tissue deficiencies at implant sites without mucosal inflammation. The aim of this paper was systematically review the lit

9. Intraspecific food resource partitioning in Brazilian silverside Atherinella brasiliensis (Atheriniformes: Atherinopsidae) in a tropical estuary, Brazil
RESUMO Nós investigamos a partição intraespecífica de recursos alimentares do peixe-rei Atherinella brasiliensis em um estuário tropical. Um total de 1.099 estômagos foi analisado, e a dieta foi constituída principalmente de Gastropoda, Larva de Ceratopogonidae, Larva de Decapoda, Calanoida, Cyclopoida, Hymenoptera e Brachyura. A análise de ordenaç�

10. Upstream and downstream migration speed of Prochilodus costatus (Characiformes: Prochilodontidae) in upper São Francisco basin, Brazil
RESUMO Detalhes acerca da dinâmica migratória de peixes neotropicais são pouco conhecidos. O objetivo deste estudo foi analisar as velocidades em migração ascendente (reprodutiva) e descendente (pós-reprodutiva) da curimatá-pioa (Prochilodus costatus) no rio São Francisco, Brasil. A migração ascendente concentrou-se nos meses de outubro e novembro,

11. CROP DATA RETRIEVAL USING EARTH OBSERVATION DATA TO SUPPORT AGRICULTURAL WATER MANAGEMENT
ABSTRACT Accurate crop data are essential for reliable irrigation water requirements (IWR) calculations, which can be acquired during the crop growth season for a given region using earth observation (EO) satellite time series. In addition, a relationship between crop coefficients and the NDVI can be established to allow for crop evapotranspiration estimatio

12. Conductas de riesgo hacia la infección por VIH. Una revisión de tendencias emergentes
Abstract HIV infection, acquired with the conscious participation of the recipient, is a complex problem of international concern, especially among men who have sex with men. Behaviors emerge such as bareback (intentionally unprotected anal sex between men) and bugchasing (bareback sex when one participant is HIV+ and the other is not). A group of emerging r
