The control of insect pests in stored grains carried out through insecticides that may select resistant populations and generate environmental risks. Secondary plant compounds are alternatives to control insect pests. However, the high volatility has been an obstacle in their practical use. This study develops natural dispersants for the application of Mentha piperit a essential oil for the control of Sitophilus zeamais (Motsc...
Soil Microbial Diversity and Network Organization Respond to Land Use and Agricultural Inputs WorldwideNARA Subscribed
Soil microbiomes are critical for ecosystem functioning, yet the global influences of climate and agricultural practices on their diversity and structure remain incompletely characterized. Here we analyzed 1921 soil samples from 33 countries worldwide across diverse biomes to assess how climate gradients and agricultural inputs, including pesticides and fertilizers, shape prokaryotic and fungal communities. We found that micro...
This study evaluated the physiological, metabolic and oxidative responses of Colossoma macropomum subjected to air exposure when maintained in water at suboptimal temperature (23°C). A total of 54 fish (81.33 ± 11.90 g) were distributed into nine tanks (6 fish per tank). For the air exposure test, 24 animals were exposed for 30 min and another 24 animals for 60 min. Six fish from each group were sampled immediately after expos...
Time-resolved network metabolomics reveals metabolic reprogramming and network stability in cowpea leaves during virus infectionNARA Subscribed
Cowpea severe mosaic virus (CPSMV) represents a major constraint for cowpea ( Vigna unguiculata (L.) Walp.) cultivation. However, the metabolic basis underlying CPSMV resistance remains poorly understood. Given the importance of metabolism for plant defence against pathogens, we hypothesized that cowpea resistance to CPSMV is associated to the activation of defence-related pathways from both primary and secondary metabolisms....
Carbonate microfacies and paleoenvironmental evolution of the Romualdo Formation (late Aptian/early Albian), Araripe Basin (NE, Brazil)NARA Subscribed
The Romualdo Formation, located in the Araripe Basin (NE, Brazil), represents an important sedimentary record of the late Aptian/early Albian transition, evidencing the establishment of a mixed siliciclastic–carbonate platform influenced by eustatic oscillations and marine ingressions associated with the breakup of Gondwana. Detailed analysis of thin sections from the Santo Antônio, Cedro, and Sobradinho sections revealed eigh...
Lepidocybium flavobrunneum [Smith, 1843], commonly known as escolar, is a large pelagic species, important for global and local fisheries, particularly in the southwestern South Atlantic Ocean (SWAO), where it constitutes a significant portion of the catch. However, despite its important socioeconomic role, it remains less studied compared to other large pelagic species. Enhancing research efforts is therefore key to better un...
Peripheral microRNA signature in genetic frontotemporal dementia—findings from the GENFI initiativeNARA Subscribed
Frontotemporal dementia (FTD) is a neurodegenerative disease characterized by significant clinical and genetic heterogeneity, with approximately 40% of cases linked to hereditary genetic mutations, including MAPT , GRN , and C9ORF72 . Recently, microRNAs (miRNAs) have emerged as key regulators of cellular processes related to neurodegeneration and as potential biomarkers for FTD. However, their relevance in presymptomatic stag...
Nutritional and metabolic responses of sheep fed banana leaf hay treated with sodium hydroxideNARA Subscribed
Our objective was to evaluate the impacts of the treatment of banana leaf hay with levels of sodium hydroxide (NaOH) on intake, digestibility, feeding behavior, and blood parameters of sheep. Five ½ Santa Ines × Dorper sheep with body weight of 38.43 ± 4.38 kg were used in a Latin square design. Treatments were based on levels of NaOH in banana leaf hay, as follows: 0; 1.25; 2.5; 3.75 and 5%. Overall, the intakes of dry matter...
Understanding complex migration patterns, including drivers of partial migration and habitat use, is challenging but essential for conservation, as it determines a species' adaptative capacity in the face of environmental change and anthropogenic threats. Therefore, we investigated the traits of partial migration and spawning use in the long‐distance migratory and ecosystem engineering fish Prochilodus costatus (pioa). Data fr...
Background Posttraumatic stress disorder (PTSD) is increasingly recognized as a sequela of subarachnoid hemorrhage (SAH); however, its prevalence and clinical correlates remain understudied. This study assessed the prevalence of PTSD symptoms and associated psychological symptoms among survivors of SAH. Methods A 6-month prospective analysis of 45 SAH survivors from the GASH trial (NCT03569540) was conducted. PTSD symptoms wer...
The initial development of the digestive system and the expression of the genes that codify the proteolytic enzymes – pepsin and trypsin – and the peptide transporter – pept1 – were investigated in the larvae of the tambaqui, Colossoma macropomum . The larvae were raised in recirculating aquaculture system (27.99 ± 0.05°C) until 36 Days After Hatching (DAH), being then fed on Artemia nauplii up to 21 DAH, when pelleted feed (5...
