Abstract Bongkrekic acid (BA) toxin, produced by Burkholderia gladioli pathovar cocovenenans bacteria, has been implicated in foodborne illness outbreaks. BA poisoning is associated with rice noodle consumption; hence, this study investigated B. growth and production wet noodles comprising varying starch ratios, types, nutrients, saccharides. Noodles 100% flour had concentrations 47.7 times higher than that of samples (30.53 ± 1.08 mg∙kg-1 VS 0.65 0.03 mg∙kg-1). Moreover, protein powder...

The integration of surface-enhanced Raman scattering (SERS) spectroscopy with magnetic fluid provides significant utility in point-of-care (POC) testing applications. Bifunctional magnetic-plasmonic composites have been widely employed as SERS substrates. In this study, a simple and cost-effective approach was developed to synthesize substrates by decorating silver nanoparticles onto Fe3O4 (AgMNPs), which function both SERS-active particles. strong responsivity from AgMNPs can isolate,...

Atopic dermatitis (AD) is a prevalent inflammatory skin condition characterized by multifaceted pathogenesis, which encompasses immune system signaling dysregulation, compromised barrier function, and genetic influencers. Sacha inchi (Plukenetia volubilis L.) oil (SIO) has demonstrated potent anti-inflammatory antioxidant properties, however, the mechanism underlying beneficial effects of SIO on AD remains unclear. This study aims to investigate anti-AD effect its possible molecular in mice...

Enzymatically converted chicken bile (CB), prepared by converting taurine deoxycholic acid (TCDCA) to ursodeoxycholic (TUDCA) in CB, possesses various functional activities. But their nutrient composition and safety assessment have not been fully investigated yet. CB was mainly composed of proteins steroids. did show genotoxic effects based on Ames test, mammalian erythrocyte micronucleus vitro chromosomal aberration test. There were no growth abnormalities or deaths the acute toxicity test...

Delaying skin-aging through diet is a hot research topic in recent years, but the anti-aging effects of fish gelatin and related mechanisms are not well understood.

Accurate estimation of communication bandwidth is critical for the sensing and controlling applications smart grid. Different from public network, requirements grid network must be accurately estimated in prior to deployment or even building network. However, existing methods usually model nodes coarse-grained ways, so their estimations become inaccurate scenarios where same type have very different requirements. To solve this issue, we propose a fine-grained method based on multivariate...
