A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

TRACEABILITY AND CERTIFICATION IN MEAT SUPPLY CHAINS [PDF]

open access: yes
Food safety problems such as the BSE and dioxin crises focused attention on traceability systems and the certification of such systems. This study analyzes the status and perspectives of traceability systems and certification schemes, and reviews their ...

Promiscuous stimulation of HSP70 ATPase activity by parasite‐derived J‐domains

open access: yesFEBS Open Bio, EarlyView.
The malaria parasite Plasmodium falciparum exports three highly homologous yet functionally divergent J‐domain proteins into human erythrocytes. Here, we show that J‐domains isolated from all three proteins effectively stimulate the ATPase activity of both endogenous host and exported parasite HSP70 chaperones.

Meat Slaughter and Processing Plants’ Traceability Levels Evidence From Iowa [PDF]

open access: yes
In the United States (U.S.), there is no uniform traceability regulation across food sector. Food and Drug Administration (FDA) implemented one-step back and one-step forward traceability over the industries under its jurisdiction. U.S.

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

open access: yesFEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

open access: yesFEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Traceability -- A Literature Review [PDF]

open access: yes
In light of recent food safety crises and international trade concerns associated with food or animal associated diseases, traceability has once again become important in the minds of public policymakers, business decision makers, consumers and special ...

Rapid Screening for Hazardous Substances with Regulatory Differences in Milk Between Countries Using Ultra-High Performance Liquid Chromatography Ion Mobility Quadrupole Time-of-Flight Mass Spectrometry

open access: yesFoods
Regulatory heterogeneity on the maximum residue levels (MRLs) of hazardous substances for food is identified as a challenge of trade between countries. To balance the import and export trade of milk, a high-throughput determination method was established

A novel non-enzyme sensor based on a PDDA-RGO/Pt NPs nanocomposite for electrochemical detection of ascorbic acid

open access: yesInternational Journal of Electrochemical Science, 2019
Enzyme-based sensors exhibit some inevitable shortcomings based on short storage times, poor stability and high cost. In this paper, we used platinum nanoparticles (Pt NPs) instead of enzymes to catalyze the detection of ascorbic acid; thus, we developed
