Inhibition of feeding by a generalist insect due to increased volatile leaf terpenes under nitrate-limiting conditions.

Journal of chemical ecology

Mihaliak CA, Couvet D, Lincoln DE.
PMID: 24301540
J Chem Ecol. 1987 Nov;13(11):2059-67. doi: 10.1007/BF01012871.

Nitrogen-limited plants ofHeterotheca subaxillaris accumulate greater quantities of leaf volatile terpenes than do nitrogen-rich plants. A series of feeding trials were performed to determine if such nitrate-limited plants are better defended against generalist-feeding insect herbivores. Soybean looper (Pseudoplusia includens)...

Recurrent DNA virus domestication leading to different parasite virulence strategies.

Science advances

Pichon A, Bézier A, Urbach S, Aury JM, Jouan V, Ravallec M, Guy J, Cousserans F, Thézé J, Gauthier J, Demettre E, Schmieder S, Wurmser F, Sibut V, Poirié M, Colinet D, da Silva C, Couloux A, Barbe V, Drezen JM, Volkoff AN.
PMID: 26702449
Sci Adv. 2015 Nov 27;1(10):e1501150. doi: 10.1126/sciadv.1501150. eCollection 2015 Nov.

Relics of ancient infections are abundant in eukaryote genomes, but little is known about how they evolve when they confer a functional benefit on their host. We show here, for the first time, that the virus-like particles shown to...

Low HDL levels in sepsis versus trauma patients in intensive care unit.

Annals of intensive care

Tanaka S, Labreuche J, Drumez E, Harrois A, Hamada S, Vigué B, Couret D, Duranteau J, Meilhac O.
PMID: 28589535
Ann Intensive Care. 2017 Dec;7(1):60. doi: 10.1186/s13613-017-0284-3. Epub 2017 Jun 06.

BACKGROUND: The protective cardiovascular effect of high-density lipoproteins (HDLs) is considered to chiefly rely on reverse cholesterol transport from peripheral tissues back to the liver. However, HDL particles display pleiotropic properties, including anti-inflammatory, anti-apoptotic or antioxidant functions. Some studies...

Diabetes, adult neurogenesis and brain remodeling: New insights from rodent and zebrafish models.

Neurogenesis (Austin, Tex.)

Dorsemans AC, Couret D, Hoarau A, Meilhac O, Lefebvre d'Hellencourt C, Diotel N.
PMID: 28439518
Neurogenesis (Austin). 2017 Jan 31;4(1):e1281862. doi: 10.1080/23262133.2017.1281862. eCollection 2017.

The prevalence of diabetes rapidly increased during the last decades in association with important changes in lifestyle. Diabetes and hyperglycemia are well-known for inducing deleterious effects on physiologic processes, increasing for instance cardiovascular diseases, nephropathy, retinopathy and foot ulceration....

¹⁴N Quadrupole Resonance line broadening due to the earth magnetic field, occuring only in the case of an axially symmetric electric field gradient tensor.

Solid state nuclear magnetic resonance

Aissani S, Guendouz L, Marande PL, Canet D.
PMID: 25910551
Solid State Nucl Magn Reson. 2015 Jun-Jul;68:57-60. doi: 10.1016/j.ssnmr.2015.04.001. Epub 2015 Apr 11.

As demonstrated before, the application of a weak static B0 magnetic field (less than 10 G) may produce definite effects on the ¹⁴N Quadrupole Resonance line when the electric field gradient tensor at the nitrogen nucleus level is of...

The hierarchical island model revisited.

Genetics, selection, evolution : GSE

Vigouroux Y, Couvet D.
PMID: 14736385
Genet Sel Evol. 2000 Jul-Aug;32(4):395-402. doi: 10.1186/1297-9686-32-4-395.

Formulae were derived for the genetic differentiation between populations within a metapopulation (F(SM)), and between metapopulations (F(MT)) as functions of migration and mutation rates, size and number of populations and metapopulations. We show that F(MT) = 1 divided by...

The maintenance of nucleocytoplasmic polymorphism in a metapopulation: the case of gynodioecy.

The American naturalist

Couvet D, Ronce O, Gliddon C.
PMID: 18811401
Am Nat. 1998 Jul;152(1):59-70. doi: 10.1086/286149.

In gynodioecious species, gender is generally determined by epistatic interactions between cytoplasmic and nuclear loci. However, theoretical studies suggest that, for a joint polymorphism at both cytoplasmic and nuclear loci to be maintained in a panmictic population, selection must...

The genetics of transient populations: Research at the metapopulation level.

Trends in ecology & evolution

Olivieri I, Couvet D, Gouyon PH.
PMID: 21232356
Trends Ecol Evol. 1990 Jul;5(7):207-10. doi: 10.1016/0169-5347(90)90132-W.

The metapopulation concept allows us to generate new models, in which each single local population is in disequilibrium (from both demographic and genetic points of view) but the whole is stable. We review recent empirical and theoretical results showing...

Off-resonance effects and selectivity profiles in pulsed nitrogen-14 nuclear quadrupole resonance.

Solid state nuclear magnetic resonance

Guendouz L, Robert A, Retournard A, Leclerc S, Aissani S, Canet D.
PMID: 23063174
Solid State Nucl Magn Reson. 2012 Oct-Nov;47:39-46. doi: 10.1016/j.ssnmr.2012.08.004. Epub 2012 Sep 01.

In order to alleviate base-line distortions in nitrogen-14 NQR spectra originating from pulse breakthrough, low power radio-frequency (rf) pulses were applied. It is recalled that the required power is four times lower than that for an equivalent NMR experiment....
