A sensitive, simple and novel method was developed to determine diclofenac sodium (DS) using silver nanoparticles (AgNPs) as probe by resonance light scattering (RLS) technique. It was found that DS could quench the RLS intensity of AgNPs. Moreover, the decrease in RLS intensity was linearly correlated to the concentration of DS over the range of 0.01-2.0μgmL-1 . DS can be measured in a short time (5min) without any complicated or time-consuming sample pretreatment process. Parameters that affect the RLS intensities such as pH, concentration of AgNPs, reaction time, electrolyte concentration, and coexisting substances were systematically investigated and optimized...

The filter bank multicarrier (FBMC) modulation format is considered as a potential candidate for future wireless 5G due to its feature of high suppression for out-of-band emissions, which allows combining multiple sub-bands with very narrow band-gaps, and hence increases the overall wireless transmission capacity. In this paper, we experimentally demonstrate the generation of multi sub-bands FBMC signals at millimeter-wave (mm-wave) for radio-over-fiber (RoF) systems. The designed multi sub-bands FBMC system consists of 5 sub-bands of 800 MHz with inter sub-band gaps of 781...

Diego Garcia-Borreguero, Irene Cano-Pumarega, Rafael Marulanda
Dopaminergic drugs have been widely used over the last decades for the treatment of restless legs syndrome (RLS)/Willis-Ekbom disease (WED). While the majority of studies show an initial improvement in symptoms, longer studies and clinical experience show that either treatment efficacy decreases with time, and/or augmentation develops: dopaminergic augmentation has been reported to be the main reason for treatment discontinuation and treatment failure in RLS/WED. The current review discusses the main reasons for treatment failure in RLS/WED and outlines the most recent expert-based strategies to prevent and manage it...

Ramularia collo-cygni (Rcc) causes Ramularia leaf spot (RLS) disease of barley. The fungus develops asymptomatically within its host until late in the growing season when necrotic lesions become visible on upper leaves. Fungal secondary metabolites (SMs) have been proposed as important factors in RLS lesion formation, but the biosynthetic pathways involved remain largely unknown. Mining the Rcc genome revealed the presence of ten polyketide synthases (PKSs), ten non-ribosomal peptide synthetases (NRPSs) and three hybrid PKS-NRPS (HPSs) identified within clusters of genes with predicted functions associated with secondary metabolism...
