Euterpe edulis Martius (juçara palm) is an endangered species of high ecological and economic importance. Its propagation via reproduction is limited by the recalcitrance of its seeds, which hinders conservation and genetic improvement. Somatic embryogenesis represents an efficient alternative for large-scale clonal propagation and conservation. The present study evaluated the effect of abscisic acid (ABA) on histodifferentiat...
Effects of Low-Intensity Aaerobic Training on Cardiac Dysfunction and Myocardial Fibrosis Induced by Doxorubicin in Wistar RatsNARA Subscribed
Doxorubicin-induced cardiotoxicity is a major limitation in cancer therapy. Physical exercise has been proposed as a non-pharmacological strategy capable of mitigating these effects through cardiovascular adaptations. This study evaluated whether low-intensity aerobic training attenuates cardiac dysfunction induced by doxorubicin. Twenty-five adult male Wistar rats (450 and 500 g) were allocated and divided into four groups: C...
Aim We investigate the distribution of dispersal modes — endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and dispersal agents (e.g., the main vectors moving seeds). We expected climate to be the mai...
Image-based phenotyping of castor bean seeds for morphological traits, seed weight prediction, and assessment of genetic diversityNARA Subscribed
Digital seed phenotyping offers an efficient and objective alternative to conventional, labor-intensive methods for morphological characterization in plant breeding programs. In castor bean, rapid and reliable tools are essential to support genetic improvement. This study evaluated the potential of digital phenotyping for seed characterization and its application in breeding. Seeds from 65 accessions (2023) and 51 accessions (...
Virulence and Immune Response of Campylobacter jejuni Strains in Chicken Embryo ModelNARA Subscribed
This study aimed to evaluate the virulence and infection response of Campylobacter jejuni (CJ) strains isolated from chickens, as well as a standard strain isolated from humans, to understand better the pathogen-host relationship between CJ and chicken embryos (CE) with an active immune system. With its well-developed vascular structures, the CE model offers a valuable method for studying complex biological systems. We assesse...
Air pollution remains a persistent environmental and public health concern in urban regions. This study presents a 22-year analysis (2001–2022) of coarse particulate matter (PM 10 ) concentrations across 15 monitoring stations in the Porto Metropolitan Area (PMA), Portugal. The stations, pre-classified by national authorities as traffic, background-urban, background-suburban, or industrial, were used to assess long-term tempor...
