Abstract Bentazon and molinate are selective herbicides recommended for integrated weed management in rice. Their toxicity on growth and some biochemical and physiological parameters of Nostoc muscorum , an abundant cyanobacterium in Portuguese rice fields, was evaluated under laboratory conditions during time‐ and concentration‐dependent exposure for 72 h. Results showed that toxic concentrations (0.75–2 mM) of both herbicides have pleiotropic effects on the cyanobacterium. Molinate was more toxic ...

The effects of the herbicides 1,1′-dimethyl-4,4′-bipyridylium dichloride (paraquat), 3,6-dichloro-2-metoxybenzoic acid (dicamba) and 2,4-dichlorophenoxyacetic acid (2,4-D) on cell growth of non-green potato tuber calli are described. We attempted to relate the effects with toxicity, in particular the enzymes committed to the cellular antioxidant system. Cell cultures were exposed to the herbicides for a period of 4 weeks. Cellular integrity on the basis of fluorescein release was strongly affected ...

Although the main reservoir of Candida spp. is believed to be the buccal mucosa, these microorganisms can coaggregate with bacteria in subgingival biofilm and adhere to epithelial cells. Such interactions are associated with the capacity of Candida spp. to invade gingival conjunctive tissue, and may be important in the microbial colonization that contributes to progression of oral alterations caused by diabetes mellitus, some medications, and immunosuppressive diseases such as AIDS. In addition, ...

The aim of this study is to evaluate the effects of segregation and of the presence of tertiary dendrite arms in the microstructural arrangement of a Pb–Sb alloy on its resultant corrosion behavior. In this context, a water-cooled unidirectional solidification system was used to obtain alloy samples having different dendritic patterns. Electrochemical impedance spectroscopy and potentiodynamic polarization curves were used to analyze the corrosion resistance in a 0.5 M H2SO4 solution at 25 °C. Three ...

Despite its importance in chemical industries, there are few works which studies anchor type impellers and only a fraction of the works investigate these systems under a computational approach. The great majority refers to turbine impellers, specially Rushton turbines, under turbulent flow. Anchor impellers are used specially for highly viscous flow, typical of polymer reactions. The viscosity is normally in the range 1000-10000 cp. Since this range of viscosity describe highly viscous flows, the ...

Electrospun materials have been widely explored for biomedical applications because of their advantageous characteristics, i.e., tridimensional nanofibrous structure with high surface-to-volume ratio, high porosity, and pore interconnectivity. Furthermore, considering the similarities between the nanofiber networks and the extracellular matrix (ECM), as well as the accepted role of changes in ECM for hernia repair, electrospun polymer fiber assemblies have emerged as potential materials for incisional ...

Pyrethroids are the most used insecticide class worldwide. They target the voltage gated sodium channel (NaV), inducing the knockdown effect. In Aedes aegypti, the main dengue vector, the AaNaV substitutions Val1016Ile and Phe1534Cys are the most important knockdown resistance (kdr) mutations. We evaluated the fitness cost of these kdr mutations related to distinct aspects of development and reproduction, in the absence of any other major resistance mechanism. To accomplish this, we initially set ...

Aluminum (Al) effects on fatty acid composition and on the lipid peroxidation of a purified plasma membrane fraction of root apices of two sorghum cultivars were studied. Palmitic and linoleic acids were the major fatty acids in the root apices of sorghum, independent of the Al presence in nutrient solution. After Al treatment, the C18:0/C18:3 and C18:2/C18:3 ratios increased, while the C18:2/C16:0 ratio remained unchanged in the Al-sensitive cultivar but all three ratios decreased in the Al-tolerant ...

To model the catalytic cracking of petroleum fractions, population‐balance equations are solved through Galerkin formalism. It focuses on a simplified version of such equations, which was solved analytically ...
