1. Kinetic study and thermodynamic equilibrium modeling of the Co(II) and Mn(II) bioadsorption using the Rhodococcus opacus strain
Abstract Microbial biomass is considered a renewable and environmentally friendly resource. Thus, the research conducted a kinetic study and thermodynamic equilibrium modeling of the cobalt (Co) and manganese (Mn) bioadsorption process using the Rhodococcus opacus (RO) strain as a biosorbent. The inactive biomass subjected to 0.1 M NaOH pretreatment was brou

2. Biochemical and Molecular Mechanisms of Glucose Uptake Stimulated by Physical Exercise in Insulin Resistance State: Role of Inflammation
Resumo A obesidade associada à inflamação sistêmica induz resistência à insulina (RI), com consequente hiperglicemia crônica. Este processo envolve o aumento na liberação de citocinas pró-inflamatórias, ativação da enzima c-Jun N-terminal cinase (JNK), do fator nuclear kappa-B (NF-κB) e dos receptores do tipo Toll 4 (TLR4). Dentre as ferramenta

3. Transport of Atrazine Via Leaching in Agricultural Soil with Mineral Oil Addition
RESUMO: Os adjuvantes, como os óleos minerais, são amplamente utilizados na aplicação de herbicidas por reduzir a deriva e a evaporação das gotas, bem como por aumentar a absorção do herbicida pela planta. Contudo, pouco se sabe como o óleo mineral se comporta quando em contato com o solo. Assim, o objetivo desta pesquisa foi avaliar o transporte de

4. Gas exchange, root hydraulic conductivity, water use efficiency and the growth of Toona ciliata clones and seedlings
Resumo As plantações florestais estabelecidas com mudas apresentam heterogeneidade e dificuldades de manejo. Assim, uma alternativa a estes obstáculos é o uso de clones com alta produtividade. Além disso, as plantas clonais diferem das plantas seminíferas na estrutura do sistema radicular, o que pode influenciar a eficiência na absorção de água e d

5. Humic acids from vermicompost positively influence the nutrient uptake in mangosteen seedlings1
RESUMO A aplicação de substâncias promotoras de crescimento, a exemplo dos ácidos húmicos, no desenvolvimento de mudas frutíferas pode beneficiar o crescimento e potencializar a absorção e translocação de nutrientes na planta. Objetivou-se avaliar o efeito da aplicação de doses de ácidos húmicos (0 mg L-1; 2 mg L-1; 20 mg L-1; 40 mg L-1; 200 mg

6. Assessment of neuropharmacological potential of low molecular weight components extracted from Rhinella schneideri toad poison
Abstract Background: Studies on toad poison are relevant since they are considered a good source of toxins that act on different biological systems. Among the molecules found in the toad poison, it can be highlighted the cardiotonic heterosides, which have a known mechanism that inhibit Na+/K+-ATPase enzyme. However, these poisons have many other molecules

7. Competitive Adsorption of Dye Species onto Biomass Nanoporous Carbon in Single and Bicomponent Systems
ABSTRACT We first present a cost-effective approach to simultaneously dispose of rutaceae plant waste (the discarded peels of orange, finger citron, pomelo and lemon) to yield biomass nanoporous carbons (BNCs). The adsorption of orange II (OII) and acid chrome blue K (ACBK) from aqueous solutions in single and binary dye systems by four types of BNCs were st

8. Hydrogen sulfide: a new endogenous player in an old mechanism of plant tolerance to high salinity
ABSTRACT High salinity affects plants due to stimulation of osmotic stress. Cell signaling triggered by nitric oxide (NO) and hydrogen sulfide (H2S) activates a cascade of biochemical events that culminate in plant tolerance to abiotic and biotic stresses. For instance, the NO/H2S-stimulated biochemical events that occur in plants during response to high sal

9. Uliginosin B, a natural phloroglucinol derivative with antidepressant-like activity, increases Na+,K+-ATPase activity in mice cerebral cortex
ABSTRACT Uliginosin B, a phloroglucinol isolated from Hypericum polyanthemum Klotzsch ex Reichardt, Hypericaceae, has antidepressant-like effect in the forced swimming test in rodents and inhibits monoamines neuronal reuptake without binding to their neuronal carriers. Studies showed the involvement of Na+,K+-ATPase brain activity in depressive disorders, as

10. Variation in ion accumulation as a measure of salt tolerance in seedling and callus of Stylosanthes guianensis
Seedlings of Stylosanthes guianensis CIAT 184 (Stylo 184) were germinated under salt-stress conditions (0-170.9 mM NaCl), and germination and ion content (Cl-, Na+, Ca2+, Mg2+ and K+) were measured after seven days. The salt treatment had no effect on the germination percentage, but the seedling showed reduced growth and displayed variation in ion uptake, th

11. GESSO AGRÍCOLA E ADUBAÇÃO NITROGENADA NA CULTURA DO MILHO EM SISTEMA PLANTIO DIRETO
A considerably part of the high nitrogen (N) rates applied in corn is not absorbed due root growth restriction by subsoil acidity. Gypsum is able to improve conditions for root growth and lead to greater N uptake efficiency, increasing corn yield. Thus to evaluate the effect of gypsum and N on top dressing on soil chemical attributes, root growth , mineral n

12. Supplemental Ca2+ does not improve growth but it affects nutrient uptake in NaCl-stressed cowpea plants
The growth and nutrient assimilation was evaluated in CaCl2- and CaSO4-supplemented cowpea plants subjected to salt stress (75 mM NaCl). The salinity significantly reduced the cowpea vegetative growth. The addition of CaCl2 in the growth medium did not significantly affect plant growth, while for the CaSO4, the beneficial effects of Ca2+ were moderate. Salin
