Organic letters

Brahim M, Ben Ammar H, Dorcet V, Soulé JF, Doucet H.
PMID: 28480718
Org Lett. 2017 May 19;19(10):2584-2587. doi: 10.1021/acs.orglett.7b00900. Epub 2017 May 08.

Conditions allowing the palladium-catalyzed regioselective direct arylation of fulvene derivatives are reported. The nature of the aryl source exhibits an important influence on the yield. The reaction of fulvenes with aryl bromides gave poor yields, whereas the use of...

From Mesomorphic Phosphine Oxide to Clustomesogens Containing Molybdenum and Tungsten Octahedral Cluster Cores.

Angewandte Chemie (International ed. in English)

Cîrcu V, Molard Y, Amela-Cortes M, Bentaleb A, Barois P, Dorcet V, Cordier S.
PMID: 26211657
Angew Chem Int Ed Engl. 2015 Sep 07;54(37):10921-5. doi: 10.1002/anie.201503205. Epub 2015 Jul 21.

New clustomesogens (i.e., metal atom clusters containing liquid crystalline (LC) materials) have been obtained by grafting neutral cyanobiphenyl (CB)- or cholesteryl-containing tailor-made dendritic mesomorphic triphenylphosphine oxide ligands on luminescent (M6 Cl(i) 8 )(4+) octahedral cluster cores (M=Mo, W). The...

Ultrasound-guided "short" midline catheters for difficult venous access in the emergency department: a retrospective analysis.

Int J Emerg Med. 2016 Dec;9(1):3. doi: 10.1186/s12245-016-0100-0. Epub 2016 Feb 04.

BACKGROUND: Acutely ill patients admitted to the emergency department (ED) constantly require at least one fast and reliable peripheral intravenous (PIV) access. In many conditions (morbid obesity, underweight state, chronic diseases, intravenous drug abuse, adverse local conditions, etc.), PIV...

Thermal and near-infrared light induced spin crossover in a mononuclear iron(ii) complex with a tetrathiafulvalene-fused dipyridophenazine ligand.

Dalton transactions (Cambridge, England : 2003)

Pointillart F, Liu X, Kepenekian M, Le Guennic B, Golhen S, Dorcet V, Roisnel T, Cador O, You Z, Hauser J, Decurtins S, Ouahab L, Liu SX.

Dalton Trans. 2016 Jul 28;45(28):11267-71. doi: 10.1039/c6dt00920d. Epub 2016 Jun 30.

A mononuclear Fe(ii) complex involving a tetrathiafulvalene-based ligand exhibits thermal spin-crossover (around 143 K) with pronounced hysteresis behaviour (48 K). The chromophoric and π-extended ligand allows Near-Infrared (NIR) sensitization for the light-induced excited spin-state trapping (LIESST) with T(LIESST) =...

Sound propagation in liquid foams: Unraveling the balance between physical and chemical parameters.

Physical review. E, Statistical, nonlinear, and soft matter physics

Pierre J, Giraudet B, Chasle P, Dollet B, Saint-Jalmes A.

Phys Rev E Stat Nonlin Soft Matter Phys. 2015 Apr;91(4):042311. doi: 10.1103/PhysRevE.91.042311. Epub 2015 Apr 23.

We present experimental results on the propagation of an ultrasonic wave (40 kHz) in liquid foams, as a function of the foam physical and chemical parameters. We have first implemented an original setup, using transducers in a transmission configuration....

Robust Electrografting on Self-Organized 3D Graphene Electrodes.

ACS Appl Mater Interfaces. 2016 Jan 20;8(2):1424-33. doi: 10.1021/acsami.5b10647. Epub 2016 Jan 11.

Improving graphene-based electrode fabrication processes and developing robust methods for its functionalization are two key research routes to develop new high-performance electrodes for electrochemical applications. Here, a self-organized three-dimensional (3D) graphene electrode processed by pulsed laser deposition with thermal...

Vertebra segmentation based on two-step refinement.

Journal of computational surgery

Courbot JB, Rust E, Monfrini E, Collet C.

J Comput Surg. 2016;4:1. doi: 10.1186/s40244-016-0018-0. Epub 2016 Jul 26.

Knowledge of vertebra location, shape, and orientation is crucial in many medical applications such as orthopedics or interventional procedures. Computed tomography (CT) offers a high contrast between bone and soft tissues, but automatic vertebra segmentation remains difficult. Hence, the...

Motor imagery reinforces brain compensation of reach-to-grasp movement after cervical spinal cord injury.

Frontiers in behavioral neuroscience

Mateo S, Di Rienzo F, Bergeron V, Guillot A, Collet C, Rode G.
PMID: 26441568
Front Behav Neurosci. 2015 Sep 11;9:234. doi: 10.3389/fnbeh.2015.00234. eCollection 2015.

Individuals with cervical spinal cord injury (SCI) that causes tetraplegia are challenged with dramatic sensorimotor deficits. However, certain rehabilitation techniques may significantly enhance their autonomy by restoring reach-to-grasp movements. Among others, evidence of motor imagery (MI) benefits for neurological...

Osteoporosis-Pseudoglioma in a Mauritanian Child due to a Novel Mutation in LRP5.

Osteoporosis-pseudoglioma (OPPG) syndrome is a very rare autosomal recessive disorder, caused by mutations in the low-density lipoprotein receptor-related protein 5 (LRP5) gene. It manifests by severe juvenile osteoporosis with congenital or infancy-onset visual loss. We describe a case of...

Front Hum Neurosci. 2012 Sep 05;6:247. doi: 10.3389/fnhum.2012.00247. eCollection 2012.

There is now compelling evidence that motor imagery (MI) and actual movement share common neural substrate. However, the question of how MI inhibits the transmission of motor commands into the efferent pathways in order to prevent any movement is...
