Pyridin-3-carbohydrazide strongly impairs Mayaro and Chikungunya virus replication in vitroNARA Subscribed
Alphaviruses, including Mayaro virus (MAYV) and Chikungunya virus (CHIKV), pose a growing public health threat, with increasing reports worldwide and no licensed antiviral treatments available. This study evaluated the antiviral activity of pyridine-3-carbohydrazide (P-3-C) against MAYV (strains BeAr and TRVL) and CHIKV (strain La Reunion, LR). Vero E6 or U-2OS cells were infected and treated with P-3-C for 24 h, and cell viab...
β-Lapachone exhibits potent anticancer activity although its clinical application remains limited by toxicity and mechanisms of resistance. Therefore, structural modifications have been explored to improve its pharmacological profile. This study evaluated the cytotoxic, genotoxic, and toxicological effects of the oxime derivative β-lapachone oxime (Oxβ-Lp), together with its predicted pharmacokinetic properties and potential m...
The use of herbicides in modern agriculture has been the subject of ongoing debate due to their negative impacts on the environment and human health. The aim of this study was to assess the bacterial, physicochemical and genotoxicity parameters of three soil samples of public farming settlements in Petrolândia, Brazil. The bacterial resistance patterns were examined after soil exposures to a known concentration of glyphosate (...
What percentage of neuromuscular strength reduction in older adults determines the decline in walking speed?NARA Subscribed
Background/Objective Although different neuromuscular strength (NS) cutoff points have been proposed to identify low walking speed (WS) in older adults, the extent to which NS changes predict long-term WS decline remains unclear. This study aimed to determine the percentage of NS change associated with WS decline in older adults. Methods A longitudinal analysis was conducted using data from 4,541 participants aged ≥ 60 years i...
Effects of deforestation on multitaxa community similarity in the Brazilian Atlantic ForestNARA Subscribed
Habitat loss can lead to biotic homogenization (decrease in β diversity) or differentiation (increase in β diversity) of biological communities. However, it is unclear which of these ecological processes predominates in human‐modified landscapes. We used data on vertebrates, invertebrates, and plants to quantify β diversity based on species occurrence and abundance among communities in 1367 landscapes with varying amounts of h...
Atlantic flower–invertebrate interactions: A data set of occurrence and frequency of floral visitsNARA Subscribed
Encounters between flowers and invertebrates are key events for the functioning of tropical forests. Assessing the structure of networks composed of the interactions between those partners leads to a better understanding of ecosystem functioning and the effects of environmental factors on ecological processes. Gathering such data is, however, costly and time‐consuming, especially in the highly diverse tropics. We aimed to prov...
Rock n' Seeds: A database of seed functional traits and germination experiments from Brazilian rock outcrop vegetationNARA Subscribed
Advancing functional ecology depends fundamentally on the availability of data on reproductive traits, including those from tropical plants, which have been historically underrepresented in global trait databases. Although some valuable databases have been created recently, they are mainly restricted to temperate areas and vegetative traits such as leaf and wood traits. Here, we present Rock n' Seeds, a database of seed functi...
Ants, an ecologically successful and numerically dominant group of animals, play key ecological roles as soil engineers, predators, nutrient recyclers, and regulators of plant growth and reproduction in most terrestrial ecosystems. Further, ants are widely used as bioindicators of the ecological impact of land use. We gathered information of ant species in the Atlantic Forest of South America. The ATLANTIC ANTS data set, which...
