Resist or perish: Fate of a microbial population subjected to a periodic presence of antimicrobial

Anne-Florence Raphaëlle Bitbol

The evolution of antimicrobial resistance can be strongly affected by variations of antimicrobial concentration. Here, we study the impact of periodic alternations of absence and presence of antimicrobial on resistance evolution in a microbial population, ...

Elevated HLA-A expression impairs HIV control through inhibition of NKG2A-expressing cells

Jacques Fellay

The highly polymorphic human leukocyte antigen (HLA) locus encodes cell surface proteins that are critical for immunity. HLA-A expression levels vary in an allele-dependent manner, diversifying allele-specific effects beyond peptide-binding preference. Ana ...

The Combined Effect of Oseltamivir and Favipiravir on Influenza A Virus Evolution

Jeffrey David Jensen, Claudia Bank, Sebastian Matuszewski, Nicky Louise Ormond

Influenza virus inflicts a heavy death toll annually and resistance to existing antiviral drugs has generated interest in the development of agents with novel mechanisms of action. Favipiravir is an antiviral drug that acts by increasing the genome-wide mu ...

The effect of overall stimulus configuration on crowding

Michael Herzog, Maya Roinishvili, Mattew Pachai

The standard framework to study vision is typically hierarchical and feedforward, which facilitates deconstructing complex mechanisms into smaller, more tractable problems. However, this framework can fail when elements are presented in context, as they ar ...

Comparisons of verbal fluency brain correlates between adults and adolescents suffering from schizophrenia spectrum disorders: A pilot study

Pierre Magistretti, Pierre Marquet

Background and Objectives: Prefrontal cortex (PFC) dysfunctions leading to cognitive deficits refer to a core feature of schizophrenia spectrum disorders (SSD). This exploratory study compares the effect of SSD on two stages of maturation of PFC. Methods: ...

An experimental evaluation of drug-induced mutational meltdown as an antiviral treatment strategy

Jeffrey David Jensen, Matthieu Foll, Claudia Bank, Sebastian Matuszewski, Hyunjin Shim

The rapid evolution of drug resistance remains a critical public health concern. The treatment of influenza A virus (IAV) has proven particularly challenging, due to the ability of the virus to develop resistance against current antivirals and vaccines. He ...

Deleterious effect of homogeneous and heterogeneous near-neutral photo-Fenton system on Escherichia coli. Comparison with photo-catalytic action of TiO2 during cell envelope disruption

César Pulgarin, Andrzej Sienkiewicz, Cristina del Socorro Lonfat

The mechanisms underlying bacterial inactivation by solar photo-Fenton at near-neutral pH have not yet been investigated in detail. In particular, no consensus exists on the bacterial inactivation mechanism under solar light enhanced by the Fenton's reagen ...

Influence of HLA-C Expression Level on HIV Control

Jacques Fellay, Paul Jack Mc Laren

A variant upstream of human leukocyte antigen C (HLA-C) shows the most significant genome-wide effect on HIV control in European Americans and is also associated with the level of HLA-C expression. We characterized the differential cell surface expression ...

Genetic evidence for a protective role of the peritrophic matrix against intestinal bacterial infection in Drosophila melanogaster

Bruno Lemaitre, Olivier Binggeli, Takayuki Kuraishi

The peritrophic matrix (PM) forms a layer composed of chitin and glycoproteins that lines the insect intestinal lumen. This physical barrier plays a role analogous to that of mucous secretions of the vertebrate digestive tract and is thought to protect the ...

Synchrotron Infrared Microspectroscopy Detecting the Evolution of Huntington's Disease Neuropathology and Suggesting Unique Correlates of Dysfunction in White versus Gray Brain Matter

László Forró, Sylvia Jeney, Markus Bonda

Huntington's disease (HD), caused by a mutation of the corresponding gene encoding the protein huntingtin (htt), is characterized by progressive deterioration of cognitive and motor functions, paralleled by extensive loss of striatal neurons. At the cellul ...

Acute Hypoglycemia Induces Retinal Cell Death in Mouse

Background: Glucose is the most important metabolic substrate of the retina and maintenance of normoglycemia is an essential challenge for diabetic patients. Glycemic excursions could lead to cardiovascular disease, nephropathy, neuropathy and retinopathy. ...

Thermomechanical and Electrochemical Degradation in Anode-Supported Solid Oxide Fuel Cell Stacks

Arata Nakajo

The solid oxide fuel cell (SOFC) is a direct energy conversion device, which allows the production of electricity with high efficiency while maintaining pollutant emissions at a low level. It offers better fuel flexibility and lower vulnerability to impuri ...

The Interplay between Cytidine Deaminases, HIV and Domesticated Genetic Parasites

"There is more virus in us than us in us". John Coffin's famous sentence illustrates that particular nucleic acid sequences related to exogenous viruses, called retrotransposons, constitute almost half of the human genome and largely exceeds the amount of ...
