Comprehensive effects of thiamethoxam from contaminated soil on lettuce growth and metabolism
This study examined variations of growth state, physiological parameters, antioxidant activity, and metabolites in lettuce after thiamethoxam exposure; the removal effects of different washing procedures were also investigated. The results indicated that thiamethoxam in soils significantly increased the fresh weight, seedling height and chlorophyll content in lettuce, and also altered its lipid, carbohydrate, nucleotide and amino acids composition based on untargeted metabolomics. KEGG pathway analysis uncovered a disruption of lipid pathways in lettuce exposed to both low and high concentrations of thiamethoxam treatments...

An electrochemical biosensor based on phage-encoded protein RBP 41 for rapid and sensitive detection of Salmonella
In this study, an electrochemical biosensor was developed using a newly identified biorecognition element, RBP 41, which is capable of specifically recognizing and binding to Salmonella. The biosensor was constructed through a layer-by-layer assembly of graphene oxide (GO), gold nanoparticles (GNPs), and RBP 41 on a glassy carbon electrode (GCE), with the GNPs amplifying the detection signal. The established biosensor was able to detect Salmonella in concentrations ranging from 3 to 106 CFU/mL within approximately 30 min by using differential pulse voltammetry (DPV) signal, and the estimated detection limit was to be 0.298...

Dispersive Solid-phase Microextraction of Lead in Waters and Edible Lettuce and Dill Extracts in the Unified Bioaccessibility Method (UBM) Saliva Solution
Biol Trace Elem Res. 2023 Dec 20. doi: 10.1007/s12011-023-04001-7. Online ahead of print.ABSTRACTA new thiosemicarbazide-modified, sulfonamide-based poly (styrene) adsorbent (T-CSPS) was prepared starting from the reaction of chlorosulfonated polystyrene and thiosemicarbazide. It was characterized by SEM-EDX, FT-IR, and zeta potential. The T-CSPS was used as an adsorbent for the first time for the dispersive solid-phase microextraction (d-SPµE) and preconcentration of Pb(II) ions from waters and dill and lettuce extracts in the unified bioaccessibility method (UBM) saliva. Lead was then determined using the FAAS. In the f...

Heat Shock Proteins in Plant Protection from Oxidative Stress
Mol Biol (Mosk). 2023 Nov-Dec;57(6):949-964.ABSTRACTThis review considers the recent progress on the role of heat shock proteins (HSPs), as well as transcription factors of heat shock proteins genes (HSFs) in protecting plants from oxidative stress induced by various types of abiotic and biotic stresses. HSPs are pleiotropic proteins involved in various intracellular processes and performing many important functions. In particular, HSPs increase plant resistance to stress by protecting the structure and activity of proteins of the antioxidant system. Overexpression of Hsp genes under stressful conditions, leading to an inc...
