Impact of virus aggregation on disinfection

This study is based on the hypothesis that viral aggregation slows the inactivation by chemical disinfectants. This slow-down depends on the aggregate size, the concentration and the reactivity of the disinfectant. In this work we test this hypothesis by e ...

Photoinactivation of virus on iron-oxide coated sand: enhancing inactivation in sunlit waters

Tamar Kohn, Brian Pecson, Loïc Decrey

Adsorption onto iron oxides can enhance the removal of waterborne viruses in constructed wetlands and soils. If reversible adsorption is not coupled with inactivation, however, infective viruses may be released when changes in solution conditions cause des ...

The dynamic architecture of Hox gene clusters

Denis Duboule, Jacques Rougemont, Marion Leleu, Daniël Noordermeer

The spatial and temporal control of Hox gene transcription is essential for patterning the vertebrate body axis. Although this process involves changes in histone posttranslational modifications, the existence of particular three-dimensional (3D) architect ...

Fate of the pathogen indicators phage phiX174 and Ascaris suum eggs during the production of struvite fertilizer from source-separated urine

Tamar Kohn, Brian Pecson, Loïc Decrey, Kai Udert

Human urine has the potential to be a sustainable, locally and continuously available source of nutrients for agriculture. Phosphate can be efficiently recovered from human urine in the form of the mineral struvite (MgNH4PO4•6H2O). However, struvite format ...

Inactivation of MS2 coliphage in Fenton and Fenton-like systems: role of transition metals, hydrogen peroxide and sunlight

Tamar Kohn, Andrzej Sienkiewicz, Jessica Ivana Nieto Juarez

The inactivation of coliphage MS2 by iron- and copper-catalyzed Fenton systems was studied to assess the importance of this process for virus inactivation in natural systems and during water treatment by advanced oxidation processes. The influence of H2O2 ...

Developement of a gateway compatible system for speciﬁc DNA integration in mouse embryonic stem cells and evaluation of the effect of nucleosome positioning on gene expression

Julien Bryois

An emerging model views gene regulation as a competition for regulatory sequences between transcription factors and nucleosomes at thermodynamic equilibrium. A computational model of the DNA affinity of nucleosomes was recently developed allowing to predic ...

Predicting the disinfection performance of a full-scale reactor in drinking water treatment is associated with considerable uncertainty. In view of quantitative risk analysis, this study assesses the uncertainty involved in predicting inactivation of Crypt ...

Nature of nonlinear imprint in ferroelectric films and long-term prediction of polarization loss in ferroelectric memories

Nava Setter, Alexander Tagantsev, Igor Stolichnov

The phenomenon of polarization imprint consisting of the development of a preferential polarization state in ferroelectric films is known as one of the major issues impacting the development of high density ferroelectric memories. According to the commonly ...

Detergent-dependent dissociation of active gamma-secretase reveals an interaction between Pen-2 and PS1-NTF and offers a model for subunit organization within the complex

Patrick Fraering

Gamma-secretase is a member of a new class of proteases with an intramembrane catalytic site and cleaves numerous type I membrane proteins, including the amyloid beta-protein precursor (APP) and the Notch receptor. Biochemical and genetic studies have iden ...

Lentiviral-mediated RNA interference

Patrick Aebischer

RNA interference (RNAi) is a form of posttranscriptional gene silencing mediated by short double-stranded RNA, known as small interfering RNA (siRNA). These siRNAs are capable of binding to a specific mRNA sequence and causing its degradation. The recent d ...
