Analogies and differences among bacterial and viral disinfection by the photo-Fenton process at neutral pH: a mini review

Stefanos Giannakis

Over the last years, the photo-Fenton process has been established as an effective, green alternative to chemical disinfection of waters and wastewaters. Microorganisms' inactivation is the latest success story in the application of this process at near-ne ...

DUX-family transcription factors regulate zygotic genome activation in placental mammals

Didier Trono, Andrea Coluccio, Evaristo Jose Planet Letschert, Julien Léonard Duc, Alberto De Iaco, Sonia Verp

In animal embryos, transcription is mostly silent for several cell divisions, until the release of the first major wave of embryonic transcripts through so-called zygotic genome activation (ZGA). Maternally provided ZGA-triggering factors have been identif ...

Genetic and epigenetic inactivation of SESTRIN1 controls mTORC1 and response to EZH2 inhibition in follicular lymphoma

Elisa Oricchio, Natalya Katanayeva, Elena Battistello, Maria Christine Donaldson, Stephanie Jocelyne Sungalee, Giovanni Ciriello

Follicular lymphoma (FL) is an incurable form of B cell lymphoma. Genomic studies have cataloged common genetic lesions in FL such as translocation t(14;18), frequent losses of chromosome 6q, and mutations in epigenetic regulators such as EZH2 Using a focu ...

Solar disinfection (SODIS) of viruses in PET bottles

Tamar Kohn, Anna Carratala Ripolles, Michael Jon Mattle, Alex Dionisio Calado

Solar disinfection of drinking water in PET bottles (SODIS) is a simple point-of-use technique efficient for the inactivation of many bacterial pathogens. In contrast, the efficiency of SODIS toward viruses is not well known. In this work, we studied the i ...

Epiblast-specific loss of HCF-1 leads to failure in anterior-posterior axis specification

Daniel Constam, Winship Herr, Sylvain Frédéric Bessonnard

Mammalian Host-Cell Factor 1 (HCF-1), a transcriptional co-regulator, plays important roles during the cell-division cycle in cell culture, embryogenesis as well as adult tissue. In mice, HCF-1 is encoded by the X-chromosome-linked Hcfc1 gene. Induced Hcfc ...

Dicer1 imparts essential survival cues in Notch-driven T-ALL via miR-21-mediated tumor suppressor Pdcd4 repression

Freddy Radtke, Ute Koch, Fabian Junker, Antoine Matthieu Chabloz

The modulatory function of individual microRNAs (miRNAs) in Notch-driven T-cell acute lymphoblastic leukemias (T-ALLs) has recently been established. Although protumorigenic and tumor-suppressive miRNAs are implicated in disease onset in murine models of N ...

Inactivation kinetics and mechanisms of viral and bacterial pathogen surrogates during urine nitrification

Tamar Kohn, Ariane Schertenleib, Kai Udert

This paper assesses the inactivation performance and mechanisms in urine nitrification reactors using bacteria and bacteriophages as surrogates for human pathogens. Two parallel continuous-flow moving bed biofilm reactors (MBBRs) were operated over a two-m ...

Inactivation of brain Cofilin-1 by age, Alzheimer's disease and gamma-secretase

Patrick Fraering, Sébastien Mosser, Eugenio Barone

Rapid remodeling of the actin cytoskeleton in the pre- and/or post-synaptic compartments is responsible for the regulation of neuronal plasticity, which is an important process for learning and memory. Cofilin1 plays an essential role in these processes an ...

Mechanisms of Human Adenovirus Inactivation by Sunlight and UVC Light as Examined by Quantitative PCR and Quantitative Proteomics

Tamar Kohn, Romain Hamelin, Florence Armand, Franziska Sara Bosshard

Human adenoviruses (HAdV) are important pathogens in both industrialized and developing nations. HAdV has been shown to be relatively resistant to monochromatic UVC. Polychromatic UVC, in contrast, is a more effective means of disinfection, presumably due ...

RF-plasma pretreatment of surfaces leading to TiO2 coatings with improved optical absorption and OH-radical production

César Pulgarin, Juan Kiwi, Sami Rtimi, Christophe Roussel, Oualid Baghriche

Evidence is presented for the RF pretreatment of polyester enhances the TiO2 coating generation of oxidative species/radicals under a low level actinic light irradiation. After 30 min RF-plasma pretreatment of the polyester samples, the fastest bacterial i ...
