Fusarium virguliforme causes sudden death syndrome (SDS) in soybean. The pathogen has never been isolated from diseased foliar tissues; therefore, one or more toxins have been considered to cause foliar SDS development. Cell-free F. virguliforme culture filtrates containing a toxin causes foliar SDS in soybean. A low-molecular-weight protein of approximately 13.5 kDa (FvTox1), purified from F. ...

Lipopolysaccharides (LPS) are the major components of the outer membrane of gram-negative bacteria. These surface molecules are relevant both for the outer membrane stability and for the interaction of the bacteria with other organisms and with the environment (18). Extensive literature is available concerning LPS physiology in different symbiotic (parasitic) and pathogenic host-bacterial inter...

Many reports highlight biological responses of crop plants after non-ionizing electromagnetic radiation (EMR) exposure based on the phenotypic and physiological levels. So, this study aimed to estimate genetic alterations in proteins, isozymes, DNA banding patterns as well extent nuclear damage economic corn (Zea mays) under stress EMR using accurate reliable bioassays like sodium dodecyl sulfa...

Surfactant-based nanostructures are promising materials for designing novel colorimetric biosensors based on aggregation/disaggregation phenomena. In this work, a sensor the plasmonic shift of surfactant-capped gold nanoparticles via disaggregation mechanism was developed. To perform this, optimum SDS concentration firstly determined in order to form Au@16-s-16/SDS complex aggregates with well-...

We present a methodology to quantitatively determine the fraction of sodium dodecyl sulfate (SDS) that partitions to the oil/water interface in oil-in-water macroemulsions and calculate the total interfacial area (TIA) through the novel use of filtration through nanoporous membranes. Ultrafiltration was carried out in centrifuge tubes having nanoporous filters with a 30,000 molecular weight cut...

BACKGROUND In chronic autonomic failure of varying aetiologies, there are differences in the cardiovascular responses to supine leg exercise and to standing after exercise. Whether this occurs between the different subgroups with Shy-Drager syndrome (SDS) is unknown. METHODS Fourteen patients with the cerebellar form (SDS-C) and 11 patients with parkinsonian features (SDS-P) were studied. R...

In this research, the influence of additives on rheological and sedimentary properties magnetorheological fluid (MRF) was tested analyzed. The were stearic acid, sodium dodecyl sulfate (SDS), their mixture, respectively. MRF composed carbonyl iron particle, silicone oil, liquid paraffin, graphite bentonite, SDS. results indicated that mainly influenced by mass fraction particle. When fractions ...

Fusarium virguliforme causes the serious disease sudden death syndrome (SDS) in soybean. Host resistance to this pathogen is partial and is encoded by a large number of quantitative trait loci, each conditioning small effects. Breeding SDS resistance is therefore challenging and identification of single-gene encoded novel resistance mechanisms is becoming a priority to fight this devastating th...

The main goal of this study was to describe the method of the synthesis of the dodecyl-, tetradecyl-, hexadecyl- and octadecyl-propylene glycol emulsifiers in the presence of selected anionic and nonionic surfactants. Acyl propylene glycol emulsifiers were produced by esterification of propane-1,2-diol (propylene glycol, PG) with C12:0-C18:0 fatty acids in the presence of anionic sodium dodecyl...

In this work, the naturally occurring beta-hairpin antimicrobial peptide protegrin-1 (PG-1) is studied by molecular dynamics simulation in all-atom sodium dodecylsulfate and dodecylphosphocholine micelles. These simulations provide a high-resolution picture of the interactions between the peptide and simple models of bacterial and mammalian membranes. Both micelles show significant disruption, ...
