PMID: 26689431
Ecol Lett. 2016 Mar;19(3):219-29. doi: 10.1111/ele.12556. Epub 2015 Dec 22.

Whether the success of alien species can be explained by their functional or phylogenetic characteristics remains unresolved because of data limitations, scale issues and weak quantifications of success. Using permanent grasslands across France (50 000 vegetation plots, 2000 species,...

Template-Mediated Stabilization of a DNA G-Quadruplex formed in the HIV-1 Promoter and Comparative Binding Studies.

Chemistry (Weinheim an der Bergstrasse, Germany)

Bonnat L, Bar L, Génnaro B, Bonnet H, Jarjayes O, Thomas F, Dejeu J, Defrancq E, Lavergne T.
PMID: 28264144
Chemistry. 2017 Apr 24;23(23):5602-5613. doi: 10.1002/chem.201700417. Epub 2017 Apr 05.

G-rich DNA oligonucleotides derived from the promoter region of the HIV-1 long terminal repeat (LTR) were assembled onto an addressable cyclopeptide platform through sequential oxime ligation, a thiol-iodoacetamide SN2 reaction, and copper-catalyzed azide-alkyne cycloaddition reactions. The resulting conjugate was...

In Vitro Research Tools in the Field of Human Immediate Drug Hypersensitivity and Their Present Use in Small Animal Veterinary Medicine.

Veterinary sciences

Lavergne SN.
PMID: 29056660
Vet Sci. 2016 Dec 22;4(1). doi: 10.3390/vetsci4010001.

Drug hypersensitivity reactions (DHR) are immune-mediated idiosyncratic adverse drug events. Type I DHR are often referred to as "immediate" and involve B lymphocyte-secreted IgE that bind to the membrane of basophils and mast cells, inducing their degranulation. This review...

Understanding the evolution of holoparasitic plants: the complete plastid genome of the holoparasite Cytinus hypocistis (Cytinaceae).

Annals of botany

Roquet C, Coissac É, Cruaud C, Boleda M, Boyer F, Alberti A, Gielly L, Taberlet P, Thuiller W, Van Es J, Lavergne S.
PMID: 27443299
Ann Bot. 2016 Oct 01;118(5):885-896. doi: 10.1093/aob/mcw135.

Background and Aims Plant plastid genomes are highly conserved in size, gene content and structure; however, parasitic plants are a noticeable exception to this evolutionary stability. Although the evolution of parasites could help to better understand plastome evolution in...

Spur reactions observed by picosecond pulse radiolysis in highly concentrated bromide aqueous solutions.

The journal of physical chemistry. A

El Omar AK, Schmidhammer U, Balcerzyk A, LaVerne J, Mostafavi M.
PMID: 23441977
J Phys Chem A. 2013 Mar 21;117(11):2287-93. doi: 10.1021/jp312023r. Epub 2013 Mar 12.

The formation of the well-known product Br3(-), observed in the steady-state radiolysis of highly concentrated Br(-) aqueous solutions, has now been directly observed at ultrashort times corresponding to the relaxation of the spur. The transient absorption induced by picosecond...

Spatial mismatch of phylogenetic diversity across three vertebrate groups and protected areas in Europe.

Diversity & distributions

Zupan L, Cabeza M, Maiorano L, Roquet C, Devictor V, Lavergne S, Mouillot D, Mouquet N, Renaud J, Thuiller W.
PMID: 24791146
Divers Distrib. 2014 Jun 01;20(6):674-685. doi: 10.1111/ddi.12186.

AIM: We investigate patterns of phylogenetic diversity in relation to species diversity for European birds, mammals and amphibians, to evaluate their congruence and highlight areas of particular evolutionary history. We estimate the extent to which the European network of...

Human-aided admixture may fuel ecosystem transformation during biological invasions: theoretical and experimental evidence.

Ecology and evolution

Molofsky J, Keller SR, Lavergne S, Kaproth MA, Eppinga MB.
PMID: 24772269
Ecol Evol. 2014 Apr;4(7):899-910. doi: 10.1002/ece3.966. Epub 2014 Feb 23.

Biological invasions can transform our understanding of how the interplay of historical isolation and contemporary (human-aided) dispersal affects the structure of intraspecific diversity in functional traits, and in turn, how changes in functional traits affect other scales of biological...

Unravelling the architecture of functional variability in wild populations of .

Functional ecology

Boucher FC, Thuiller W, Arnoldi C, Albert CH, Lavergne S.
PMID: 24790285
Funct Ecol. 2013 Apr 01;27(2):382-391. doi: 10.1111/1365-2435.12034.

Functional variability (FV) of populations can be decomposed into three main features: the individual variability of multiple traits, the strength of correlations between those traits and the main direction of these correlations, the latter two being known as 'phenotypic...

Combining an expert-based medical entity recognizer to a machine-learning system: methods and a case study.

Biomedical informatics insights

Zweigenbaum P, Lavergne T, Grabar N, Hamon T, Rosset S, Grouin C.
PMID: 24052691
Biomed Inform Insights. 2013 Aug 01;6:51-62. doi: 10.4137/BII.S11770. eCollection 2013.

Medical entity recognition is currently generally performed by data-driven methods based on supervised machine learning. Expert-based systems, where linguistic and domain expertise are directly provided to the system are often combined with data-driven systems. We present here a case...

Microbes on the cliff: alpine cushion plants structure bacterial and fungal communities.

Front Microbiol. 2013 Mar 27;4:64. doi: 10.3389/fmicb.2013.00064. eCollection 2013.

Plants affect the spatial distribution of soil microorganisms, but the influence of the local abiotic context is poorly documented. We investigated the effect of a single plant species, the cushion plant Silene acaulis, on habitat conditions, and microbial community....

Determining local geometrical features of grain boundaries from microscopy.

Grain boundaries are solid-solid interfaces whose dynamics is driven by their local curvature. As they are fluctuating interfaces and have a width comparable to the lattice spacing of the surrounding grains, the determination of their local geometrical characteristics is...
