Analysis of temporal gene regulation of Listeria monocytogenes revealed distinct regulatory response modes after exposure to high pressure processing
Nikparvar, Bahareh; Andreevskaya, Margarita; Duru, Ilhan C.; Bucur, Florentina I.; Leontina, Grigore-Gurgu; Borda, Daniela; Nicolau, Anca I.; Riedel, Christian U.; Auvinen, Petri; Bar, Nadav (Peer reviewed; Journal article, 2021)Background The pathogen Listeria (L.) monocytogenes is known to survive heat, cold, high pressure, and other extreme conditions. Although the response of this pathogen to pH, osmotic, temperature, and oxidative stress has ... -
The complete genome sequence of Listeria monocytogenes strain S2542 and expression of selected genes under high-pressure processing
Duru, Ilhan Cem; Bucur, Florentina Ionela; Andreevskaya, Margarita; Ylinen, Anne; Crauwels, Peter; Grigore-Gurgu, Leontina; Nikparvar, Bahareh; Rode, Tone Mari; Laine, Pia; Paulin, Lars; Løvdal, Trond; Riedel, Christian U.; Bar, Nadav; Borda, Daniela; Nicolau, Anca Ioana; Auvinen, Petri (Peer reviewed; Journal article, 2021)Objectives The study aims to generate the whole genome sequence of L. monocytogenes strain S2542 and to compare it to the genomes of strains RO15 and ScottA. In addition, we aimed to compare gene expression profiles of ... -
Constrained Fourier estimation of short-term time-series gene expression data reduces noise and improves clustering and gene regulatory network predictions
Bar, Nadav; Nikparvar, Bahareh; Doni Jayavelu, Naresh; Roessler, Fabienne Krystin (Peer reviewed; Journal article, 2022)Background Biological data suffers from noise that is inherent in the measurements. This is particularly true for time-series gene expression measurements. Nevertheless, in order to to explore cellular dynamics, scientists ... -
A Diffusion Model to Quantify Membrane Repair Process in Listeria Monocytogenes Exposed to High Pressure Processing based on Fluorescence Microscopy Data
Nikparvar, Bahareh; Subires, Alicia; Capellas, Marta; Hernandez-Herrero, Manuela; Crauwels, Peter; Riedel, Christian U.; Bar, Nadav (Peer reviewed; Journal article, 2021)The effects of environmental stresses on microorganisms have been well-studied, and cellular responses to stresses such as heat, cold, acids, and salts have been extensively discussed. Although high pressure processing ... -
High-pressure processing-induced transcriptome response during recovery of Listeria monocytogenes
Duru, IC; Bucur, FI; Andreevskaya, Margarita; Nikparvar, Bahareh; Ylinen, Anne; Grigore-Gurgu, L; Rode, Tone Mari; Crauwels, Peter; Laine, P; Paulin, L; Løvdal, Trond; Riedel, Christian U.; Bar, Nadav; Borda, Daniella; Nicolau, Anca Ioana; Auvinen, Petri (Peer reviewed; Journal article, 2021)Background High-pressure processing (HPP) is a commonly used technique in the food industry to inactivate pathogens, including L. monocytogenes. It has been shown that L. monocytogenes is able to recover from HPP injuries ... -

It has been shown that L. monocytogenes is able to recover from HPP injuries ... -
Modelling and analysis of the response of Listeria monocytogenes to high pressure processing
Nikparvar, Bahareh (Doctoral theses at NTNU;2022:58, Doctoral thesis, 2022)The effects of environmental stresses on microorganisms have been well-studied, and cellular responses to stresses such as heat, cold, acids, and salts have been extensively discussed. Some previous works studied the membrane, ...
