Highly sensitive and label free on-site monitoring immunosensor for detection of Aflatoxin B < sub > 1 < /sub > from real samples
Anal Biochem. 2024 Feb 23:115493. doi: 10.1016/j.ab.2024.115493. Online ahead of print.ABSTRACTAflatoxin B1 (AF-B1) are toxins secreted by secondary metabolites of molds that have adverse effects on humans and animals resulting in huge economic losses. Here we report on field useable, cost effective and direct electrochemical sensor based on conducting polymer composite electrode, Poly (3,4-ethylenedioxythiophene): polystyrene sulphonic acid (PEDOT-PSS) for label-free detection of AF-B1. Structural and morphological characterization of composite electrodes were carried out using XRD and SEM. We compared two different elect...

Rapid identification of mushroom toxins by direct electrospray probe mass spectrometry for emergency care
Anal Chim Acta. 2024 Apr 1;1296:342343. doi: 10.1016/j.aca.2024.342343. Epub 2024 Feb 6.ABSTRACTMushroom poisoning occurs frequently after the ingestion of toxic wild mushrooms misidentified as edible species. The goal of this study is to develop a mass spectrometric platform to bypass the need for morphological recognition of poisonous mushrooms by experts and rapidly identify the toxins in the mushrooms for emergency care. Trace mushroom toxins were collected by penetrating and removing the mushrooms surface for 3 mm with a direct electrospray probe (DEP). The analytes on the DEP were then dissolved in the solution (70% ...

Mushroom Tyrosinase: Six Isoenzymes Catalyzing Distinct Reactions
Chembiochem. 2024 Feb 22:e202400050. doi: 10.1002/cbic.202400050. Online ahead of print.ABSTRACT"Mushroom tyrosinase" from the common button mushroom is the most frequently used source of tyrosinase activity, both for basic and applied research. Here, the complete tyrosinase family from Agaricus bisporus var. bisporus (abPPO1-6) was cloned from mRNA and expressed heterologously using a single protocol. All six isoenzymes accept a wide range of phenolic and catecholic substrates, but display pronounced differences in their specificity and enzymatic reaction rate. AbPPO3 ignores γ-l-glutaminyl-4-hydroxybenzene (GHB), a natu...

Robust and consistent measures of pattern separation based on information theory and demonstrated in the dentate gyrus
by Alexander D. Bird, Hermann C.z, Peter Jedlicka
Pattern separation is a valuable computational function performed by neuronal circuits, such as the dentate gyrus, where dissimilarity between inputs is increased, reducing noise and increasing the storage capacity of downstream networks. Pattern separation is studied from bothin vivo experimental and computational perspectives and, a number of different measures (such as orthogonalisation, decorrelation, or spike train distance) have been applied to quantify the process of pattern separation. However, these are known to give conclusions that can differ qualitatively depen...
