The larviculture of Steindachneridion spp. faces low survival rates due to early cannibalism. The literature indicates that the larviculture of this genus is complex due to high intraspecific aggressiveness influenced by factors such as luminosity and food density. Aiming to evaluate practical strategies, a 20-day experimental trial was conducted with "suruvi-bocudo" ( S. scriptum ) post-larvae (PL) in a completely randomized...
Melatonin has been extensively studied for its antioxidant activity, yet its safety profile and concentration-dependent effects remain only partially understood, particularly in aquatic experimental systems. Here, we investigated the effects of melatonin on behavioral and physiological responses in a pilocarpine (PILO)-induced seizure-like model using zebrafish ( Danio rerio ) larvae. A multibiomarker framework was employed, c...
Age-specific climate sensitivity of respiratory hospitalizations in a tropical coastal city: 20-year Random Forest forecastsNARA Subscribed
Respiratory diseases remain a major public health challenge in tropical coastal cities, where persistent heat-humidity interactions and climate variability shape population vulnerability. This study quantified associations between atmospheric conditions and respiratory hospitalizations in Maceió, Brazil, using a 20-years time series (2000–2019). Weekly hospitalization rates stratified by age (children 0–4 years, adults 5–59 ye...
Long-Term Cropping System Diversification Under no-Till Improves Soil Structure, Carbon Stocks, and Crop Yield in Tropical EnvironmentsNARA Subscribed
Conservation agriculture (CA) is a promising strategy for restoring soil quality, increasing crop production, and mitigating climate change. However, information on the effects of long-term no-till and cropping system diversification on soil quality, carbon dynamics, and crop productivity in tropical environments remains limited. This study evaluated the effects of ten years of diversified cropping systems under no-till manage...
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...
Long-term crop diversity improves soil chemical attributes, nutrient cycling and soybean yieldNARA Subscribed
Cover crops have the potential to reduce agricultural inputs, but the long-term impacts of cover crops on soil chemical properties and nutrient cycling in tropical systems are not fully understood. This study evaluated the impact of different cover crop systems under long-term no-tillage on shoot dry mass (SDM) production, nutrient cycling, soil chemical properties, and soybean yield in succession in the Cerrado region of Mato...
Lectins are carbohydrate-binding proteins involved in diverse biological processes and with increasing relevance in biotechnological applications. In this study we report the structural characterization of a lectin from the marine red alga Amansia multifida (AML). Mass spectrometry analysis revealed two major isoforms with molecular masses of 28,388 Da and 28,661 Da. The primary structure of a lectin with a molecular weight of...
