Bioactive compounds in the cereal grains before and after hydrothermal processing
TL;DR: The behaviour of biologically active compounds under extrusion cooking, taken as a model of hydrothermal processes, was analyzed and an increase in the content of phenolic acids (free and released from ester bonds) reached from 200 to 300%.
Journal ArticleDOI
The influence of electromagnetic pollution on living organisms: historical trends and forecasting changes.
Grzegorz Redlarski,Bogdan Lewczuk,Arkadiusz Żak,Andrzej Koncicki,Marek Krawczuk,Janusz Piechocki,Kazimierz Jakubiuk,Piotr M. Tojza,Jacek Jaworski,Dominik Ambroziak,Łukasz Skarbek,Dawid Gradolewski +11 more
TL;DR: The influence of electromagnetic radiation on lower organisms was investigated, including bacteria, E. coli and B. coli, subtilis, nematode, Caenorhabditis elegans, land snail, Helix pomatia, common fruit fly, and clawed frog, Xenopus laevis.
Journal ArticleDOI
Influence of electric, magnetic, and electromagnetic fields on the circadian system: current stage of knowledge.
Bogdan Lewczuk,Grzegorz Redlarski,Arkadiusz Zak,Natalia Ziółkowska,Barbara Przybylska-Gornowicz,Marek Krawczuk +5 more
TL;DR: This paper reviews the data on the effect of electric, magnetic, and electromagnetic fields on melatonin and cortisol rhythms—two major markers of the circadian system as well as on sleep and provides the basic information about the nature, classification, parameters, and sources of these fields.
Journal ArticleDOI
The Effects of Low Doses of Two Fusarium Toxins, Zearalenone and Deoxynivalenol, on the Pig Jejunum. A Light and Electron Microscopic Study
Barbara Przybylska-Gornowicz,Michał Tarasiuk,Bogdan Lewczuk,Magdalena Prusik,Natalia Ziółkowska,Łukasz Zielonka,Maciej Gajęcki,Magdalena Gajęcka +7 more
TL;DR: The results indicate that immune cells are the principal target of low doses of ZEN and DON, and neither mycotoxin induced significant adverse changes in the ultrastructure of the mucosal epithelium and the lamina propria or in the intestinal barrier permeability.
Journal ArticleDOI
Effects of Deoxynivalenol and Zearalenone on the Histology and Ultrastructure of Pig Liver.
Natalia Skiepko,Barbara Przybylska-Gornowicz,Magdalena Gajęcka,Maciej Gajęcki,Bogdan Lewczuk +4 more
TL;DR: The results show that low doses of mycotoxins used in the present study, even when applied for a short period, affected liver morphology.
