Optimization of elastic wave propagation in a reconfigurable medium by genetic algorithms with adaptive mutation probability
Romain Christophe Rémy Fleury, Janez Rus
We introduce a reconfigurable medium for the manipulation of elastic propagation properties of Lamb waves. It is based on a shape memory polymer (SMP) with temperature-dependent Young's modulus. Waves are excited by a laser pulse and detected by a laser vi ...
IOP Publishing Ltd2023The role of the NF-kappaB pathway in Amyotrophic lateral sclerosis pathogenesis
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative motor disorder, which results in death within a few years of diagnosis. While the cause of most cases of ALS is unknown, 10% of cases are familial (fALS), and associated with mutations in one of ov ...
EPFL2023Cryo-EM structures and binding of mouse and human ACE2 to SARS-CoV-2 variants of concern indicate that mutations enabling immune escape could expand host range
Didier Trono, Henning Paul-Julius Stahlberg, Priscilla Turelli, Florence Pojer, Dongchun Ni, Sergey Nazarov, Kelvin Ka Ching Lau, Alexander Myasnikov, Emiko Uchikawa
nvestigation of potential hosts of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is crucial to understanding future risks of spillover and spillback. SARS-CoV-2 has been reported to be transmitted from humans to various animals after req ...
2023Dynamics of the most common pathogenic mtDNA variant m.3243A > G demonstrate frequency-dependency in blood and positive selection in the germline
The A-to-G point mutation at position 3243 in the human mitochondrial genome (m.3243A > G) is the most common pathogenic mtDNA variant responsible for disease in humans. It is widely accepted that m.3243A > G levels decrease in blood with age, and an age c ...
OXFORD UNIV PRESS2022A mitochondria-specific mutational signature of aging: increased rate of A > G substitutions on the heavy strand
Jacques Fellay, Konstantin Popadin, Dmitrii Iliushchenko, Stepan Denisov
The mutational spectrum of the mitochondrial DNA (mtDNA) does not resemble any of the known mutational signatures of the nuclear genome and variation in mtDNA mutational spectra between different organisms is still incomprehensible. Since mitochondria are ...
OXFORD UNIV PRESS2022A highly virulent variant of HIV-1 circulating in the Netherlands
We discovered a highly virulent variant of subtype-B HIV-1 in the Netherlands. One hundred nine individuals with this variant had a 0.54 to 0.74 log(10) increase (i.e., a similar to 3.5-fold to 5.5-fold increase) in viral load compared with, and exhibited ...
AMER ASSOC ADVANCEMENT SCIENCE2022Interferon Lambda Delays the Emergence of Influenza Virus Resistance to Oseltamivir
Francesco Stellacci, Paulo Henrique Jacob Silva, Chiara Medaglia
Influenza viruses are a leading cause of morbidity and mortality worldwide. These air-borne pathogens are able to cross the species barrier, leading to regular seasonal epidemics and sporadic pandemics. Influenza viruses also possess a high genetic variabi ...
2021Adapt or Perish: Evolutionary Rescue in a Gradually Deteriorating Environment
Anne-Florence Raphaëlle Bitbol, Loïc Marrec
We investigate the evolutionary rescue of a microbial population in a gradually deteriorating environment, through a combination of analytical calculations and stochastic simulations. We consider a population destined for extinction in the absence of mutan ...
2020Trametinib Induces the Stabilization of a Dual GNAQ p.Gly48Leu-and FGFR4 p.Cys172Gly-Mutated Uveal Melanoma. The Role of Molecular Modelling in Personalized Oncology
Krisztian Homicsko, Olivier Michielin, Alexandre Wicky
We report a case of an uveal melanoma patient with GNAQ p.Gly48Leu who responded to MEK inhibition. At the time of the molecular analysis, the pathogenicity of the mutation was unknown. A tridimensional structural analysis showed that G alpha(q) can adopt ...
2020FasR Regulates Fatty Acid Biosynthesis and Is Essential for Virulence of Mycobacterium tuberculosis
Mycobacterium tuberculosis, the etiologic agent of human tuberculosis, is the world's leading cause of death from an infectious disease. One of the main features of this pathogen is the complex and dynamic lipid composition of the cell envelope, which adap ...
