Forensic Sci Int. 2013 Jun 10;229(1):80-91. doi: 10.1016/j.forsciint.2013.02.041. Epub 2013 Apr 24.

This study represents the most extensive analysis of batch-to-batch variations in spray paint samples to date. The survey was performed as a collaborative project of the ENFSI (European Network of Forensic Science Institutes) Paint and Glass Working Group (EPG)...

Two major flavonoids from Ballota nigra.

Biochemical systematics and ecology

Bertrand M, Tillequin F, Bailleul F.
PMID: 10996268
Biochem Syst Ecol. 2000 Dec 01;28(10):1031-1033. doi: 10.1016/s0305-1978(00)00015-6.

Two lactoylate flavonoids, luteolin-7-lactate and luteolin-7-glucosyl-lactate were isolated from Ballota nigra. They should be used for the chemical standardization of this drug of medicinal interest.

Tandem radical and non-radical reactions mediated with thiols--a new method of cleavage of allylic amines.

Chemical communications (Cambridge, England)

Bertrand MP, Escoubet S, Gastaldi S, Timokhin VI.
PMID: 12120373
Chem Commun (Camb). 2002 Feb 07;(3):216-7. doi: 10.1039/b109781d.

Thiyl radical promotes the isomerisation of allylic amines into enamines via two consecutive hydrogen atom abstraction steps, and the subsequent polar addition of the corresponding thiol to the enamine results in the cleavage of the C-N bond via a...

Conformational transition of acidic peptides exposed to minerals in suspension.

Chemistry (Weinheim an der Bergstrasse, Germany)

Bertrand M, Brack A.
PMID: 11039539
Chemistry. 2000 Sep 15;6(18):3452-5. doi: 10.1002/1521-3765(20000915)6:18<3452::aid-chem3452>3.0.co;2-t.

Mineral surfaces probably participated in the chemical processes which led to life in the primitive oceans. The ordered conformations of simple acidic peptides exposed to insoluble minerals are described. Alternating poly(Glu-Leu) adopts a random coil conformation in water due...

Elimination of the concentration dependence in mass isotopomer abundance mass spectrometry of methyl palmitate using metastable atom bombardment.

Journal of the American Society for Mass Spectrometry

Fagerquist CK, Hellerstein MK, Faubert D, Bertrand MJ.
PMID: 11401166
J Am Soc Mass Spectrom. 2001 Jun;12(6):754-61. doi: 10.1016/S1044-0305(01)00227-6.

An important problem in mass isotopomer abundance mass spectrometry (MIAMS) is the dependence of measured mass isotopomer abundances on sample concentration. We have evaluated the role of ionization energy on mass isotopomer abundance ratios of methyl palmitate as a...

Modeling of submicrometer aerosol penetration through sintered granular membrane filters.

Journal of colloid and interface science

Marre S, Palmeri J, Larbot A, Bertrand M.
PMID: 15120292
J Colloid Interface Sci. 2004 Jun 01;274(1):167-82. doi: 10.1016/j.jcis.2004.01.003.

We present a deep-bed aerosol filtration model that can be used to estimate the efficiency of sintered granular membrane filters in the region of the most penetrating particle size. In this region the capture of submicrometer aerosols, much smaller...

Controlled association in suspensions of charged nanoparticles with a weak polyelectrolyte.

Langmuir : the ACS journal of surfaces and colloids

Howe AM, Wesley RD, Bertrand M, Côte M, Leroy J.
PMID: 16649758
Langmuir. 2006 May 09;22(10):4518-25. doi: 10.1021/la053327s.

The properties of high-pH suspensions of mixtures of silica with low-molecular-weight samples of the water-soluble polymer polyethylenimine (PEI) have been studied. At pH > 10 and low ionic strength, silica nanoparticles are stabilized by a negative surface charge, and...

Temperature-programmed pyrolysis hyphenated with metastable atom bombardment ionization mass spectrometry (TPPy/MAB-MS) for the identification of additives in polymers.

Journal of the American Society for Mass Spectrometry

Boutin M, Lesage J, Ostiguy C, Bertrand MJ.
PMID: 15337511
J Am Soc Mass Spectrom. 2004 Sep;15(9):1315-9. doi: 10.1016/j.jasms.2004.05.011.

Thermoanalytical techniques are currently used for the analysis of additives contained in polymers that cannot be easily dissolved, extracted, or hydrolyzed. With these techniques, the polymers are heated to liberate the additives trapped in the polymer matrix. If the...

Analysis of depth-of-focus of synthetic aperture antenna arrays.

Optics letters

Lucotte BM, Harvey AR.
PMID: 20548381
Opt Lett. 2010 Jun 15;35(12):2046-8. doi: 10.1364/OL.35.002046.

Interferometric synthetic aperture arrays (SAA) can be refocused at any range via digital processing of the raw data, called the visibility function. Such systems are sensitive, however, to ranging errors in digital refocusing. They, therefore, exhibit a limited depth...

Extensive ameloblastic fibroma in an adolescent patient: a case report with a follow-up of 4 years.

European journal of dentistry

Pitak-Arnnop P, Chaine A, Dhanuthai K, Bertrand JC, Bertolus C.
PMID: 19756198
Eur J Dent. 2009 Jul;3(3):224-8.

Ameloblastic fibroma (AF) is a rare odontogenic tumour of the jaw which usually occurs in the first 2 decades of life. The common clinical manifestation is a slow-growing swelling. We report a case of a 16-year-old male patient presenting...

Tissue elasticity reconstruction using linear perturbation method.

IEEE transactions on medical imaging

Kallel F, Bertrand M.
PMID: 18215911
IEEE Trans Med Imaging. 1996;15(3):299-313. doi: 10.1109/42.500139.

A new method to reconstruct the elastic modulus of soft tissue subjected to an external static compression is presented. In this approach the Newton-Raphson method is used to vary a finite element (FE) model of the elasticity equations to...
