Fine-tuning alkyl chain length in copper(II) complexes: effects on DNA binding and catalytic cleavageNARA Subscribed
Metal complexes are well known for their DNA cleavage activity. Copper is a metal that stands out for this purpose because it is able to perform cleavage through oxidative mechanisms using the Haber–Weiss cycle. We report two unprecedented copper(II) complexes ( 2 and 3 ) with long-chain ligands and compare the results with those of a previously reported complex ( 1 ), which we use as a reference in our studies. They were all...
The increasing utilization of agro-industrial waste underscores the necessity for sustainable valorization strategies consistent with circular economy principles. In this study, corn husk residue was investigated as a precursor to produce chemically activated biochars with tunable surface chemistry and porosity, enabling targeted adsorption of the cationic dye methylene blue (MB) and the anionic dye methyl orange (MO). Two act...
Influence of fruit cuticle thickness, phenolic and mineral content on Colletotrichum acutatum susceptibility in four olive cultivarsNARA Subscribed
Olive anthracnose, caused by Colletotrichum spp., remains one of the most destructive diseases affecting olive cultivation, with severe consequences for global olive production. Cultivar susceptibility is influenced by fruit maturation stage and modulated by environmental conditions; however the defense mechanisms underlying these interactions are still poorly understood. To investigate these relationships, experiments were co...
Revealing the phylogeography of Astyanax lacustris: insights from the São Francisco River cladeNARA Subscribed
The genus Astyanax is highly diverse within the family Acestrorhamphidae, and species identification remains challenging due to overlapping morphological, morphometric, meristic, and coloration traits. As a result, several taxa have been considered as species complexes or treated as synonyms. Molecular and cytogenetic approaches are essential for clarifying taxonomic boundaries and assessing potential genetic divergence among...
Subgroup-Specific Associations of GRIA Genes Encoding AMPA Glutamate Receptor Subunits with Patient Survival in MedulloblastomaNARA Subscribed
Brain cancers hijack biological systems involved in neural development and synaptic plasticity. Medulloblastoma (MB), the most common malignant brain tumor in children, is thought to arise from disruptions in neurodevelopmental programs. Glutamatergic transmission mediated by α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors (AMPARs) has been implicated in synaptic communication between adult brain tumors a...
Introduction: Lung cancer remains one of the leading causes of death worldwide, accounting for approximately 1.8 million deaths annually. In this context, low health literacy is frequent and represents a barrier to effective education on screening and early detection. The aim of this study was to translate, culturally adapt, and validate the Lung CAM questionnaire for use in Brazil, enabling the assessment of population litera...
Long-term soil health and microbiome responses to sustainable management under drought stress in tropical coffee agroecosystemsNARA Subscribed
Background and aims Implementing sustainable crop management to improve soil health can bolster plant and soil resistance to drought stress. This study evaluated the long-term impact of sustainable soil management on soil health in tropical coffee agroecosystems, focusing on how these practices influenced plant yield and quality, as well as soil microbiome composition and function under drought treatment. Methods Plots were se...
Myeloperoxidase (MPO) has been associated with a broad range of chronic inflammatory diseases since activated MPO catalyzes the production of HOCl, triggering both oxidative stress and inflammation. Since benzohydrazides are known as MPO inhibitors, a series of six N '-phenylbenzohydrazides and one quinazolin-4(3 H )-one analogue was evaluated through in vitro assays to measure inhibition of MPO, superoxide dismutase (SOD), an...
All Reforestation Methods Can Support Tropical Tree Diversity Recovery, but Drivers and Species Composition VaryNARA Subscribed
Tropical landscapes are undergoing rapid transformation due to human activities and global change. Forest restoration has emerged as a key strategy to mitigate biodiversity loss and climate warming. However, a standardized assessment of how different restoration methods contribute to biodiversity recovery and conservation remains lacking. Here, we present the first comprehensive comparison of tree diversity restoration and the...
Amino Acid Complexed Minerals Zn, Mn, and Cu Improve Bone and Intestinal Characteristics in Laying PulletsNARA Subscribed
The present study investigates the effect of partially supplemented trace minerals zinc (Zn), manganese (Mn), and copper (Cu) using 2 different sources: inorganic mineral (IM) or amino acid-complexed minerals (AACM), in pullet diets during 6 to 14 weeks. A total of 1120 Lohmann Brown Lite pullets were distributed into 40 experimental cages with 2 dietary treatments. Two dietary treatments were established: a IM supplemented wi...
