Cleft Palate Craniofac J. 2014 Jun 11; doi: 10.1597/13-232. Epub 2014 Jun 11.

Objective :  The purpose of this longitudinal retrospective study was to evaluate transverse maxillary expansion after a Schuchardt or segmental posterior subapical maxillary osteotomy (SPSMO) in patients with cleft lip and palate (CLP). A second aim was to compare...

The economic value of grassland species for carbon storage.

Science advances

Hungate BA, Barbier EB, Ando AW, Marks SP, Reich PB, van Gestel N, Tilman D, Knops JMH, Hooper DU, Butterfield BJ, Cardinale BJ.

Sci Adv. 2017 Apr 05;3(4):e1601880. doi: 10.1126/sciadv.1601880. eCollection 2017 Apr.

Carbon storage by ecosystems is valuable for climate protection. Biodiversity conservation may help increase carbon storage, but the value of this influence has been difficult to assess. We use plant, soil, and ecosystem carbon storage data from two grassland...

FTO knockdown in rat ventromedial hypothalamus does not affect energy balance.

Physiological reports

van Gestel MA, Sanders LE, de Jong JW, Luijendijk MC, Adan RA.
PMID: 25501432
Physiol Rep. 2014 Dec 11;2(12). doi: 10.14814/phy2.12152. Print 2014 Dec 01.

Single nucleotide polymorphisms (SNPs) clustered in the first intron of the fat mass and obesity-associated (FTO) gene has been associated with obesity. FTO expression is ubiquitous, with particularly high levels in the hypothalamic area of the brain. To investigate...

Combined Spectroscopic and Electrochemical Detection of a Ni(I) ⋅⋅⋅H-N Bonding Interaction with Relevance to Electrocatalytic H2 Production.

Chemistry (Weinheim an der Bergstrasse, Germany)

Kochem A, O'Hagan M, Wiedner ES, van Gastel M.

Chemistry. 2015 Jul 13;21(29):10338-47. doi: 10.1002/chem.201500954. Epub 2015 Jun 03.

The [Ni(P(R) 2 N(R') 2 )2 ](2+) family of complexes are exceptionally active catalysts for proton reduction to H2 . In this manuscript, we explore the first protonation step of the proposed catalytic cycle by using a catalytically inactive...

Measurement of the neutron lifetime using a proton trap.

Physical review letters

Dewey MS, Gilliam DM, Nico JS, Wietfeldt FE, Fei X, Snow WM, Greene GL, Pauwels J, Eykens R, Lamberty A, Van Gestel J.

Phys Rev Lett. 2003 Oct 10;91(15):152302. doi: 10.1103/PhysRevLett.91.152302. Epub 2003 Oct 10.

We report a new measurement of the neutron decay lifetime by the absolute counting of in-beam neutrons and their decay protons. Protons were confined in a quasi-Penning trap and counted with a silicon detector. The neutron beam fluence was...

Thermal motion and energetics of self-assembled domain structures: Pb on Cu(111).

Physical review letters

van Gastel R, Plass R, Bartelt NC, Kellogg GL.
PMID: 12906605
Phys Rev Lett. 2003 Aug 01;91(5):055503. doi: 10.1103/PhysRevLett.91.055503. Epub 2003 Jul 30.

Low energy electron microscope measurements of the thermal motion of 50-200 nm diameter Pb islands on Cu(111) are used to establish the nature and determine the strength of interactions that give rise to self-assembly in this two-dimensional, two-phase system....

Mechanisms of resistance to piperacillin of Enterobacter cloacae strains differ by antibiotic prescription policy.

International journal of antimicrobial agents

Namavar F, Verboom T, van de Klundert JA, van Gestel MH, Zaal J, Maclarena DM.
PMID: 18611803
Int J Antimicrob Agents. 1997;8(3):205-8. doi: 10.1016/s0924-8579(97)00377-4.

During a study of piperacillin resistance among aerobic Gram-negative bacteria, 18 resistant strains of Enterobacter cloacae were obtained from a General Hospital in Rotterdam and 13 from a University Hospital in Amsterdam. The patterns of antibiotic susceptibilities were different:...

Playing pinball with atoms.

Nano letters

PMID: 18781806
Nano Lett. 2009 May;9(5):1733-6. doi: 10.1021/nl8022884.

We demonstrate the feasibility of controlling an atomic scale mechanical device by an external electrical signal. On a germanium substrate, a switching motion of pairs of atoms is induced by electrons that are directly injected into the atoms with...

Reversible shape transition of pb islands on Cu(111).

Physical review letters

Phys Rev Lett. 2006 Jan 27;96(3):036106. doi: 10.1103/PhysRevLett.96.036106. Epub 2006 Jan 26.

Using low-energy electron microscopy, we have observed a reversible transition in the shape of Pb adatom and vacancy islands on Cu(111). With increasing temperature, circular islands become elongated in one direction. In previous work we have shown that surface...

Medipix 2 detector applied to low energy electron microscopy.

Ultramicroscopy

Low energy electron microscopy (LEEM) and photo-emission electron microscopy (PEEM) traditionally use microchannel plates (MCPs), a phosphor screen and a CCD-camera to record images and diffraction patterns. In recent years, however, MCPs have become a limiting factor for these...

Amplification of chirality in helical supramolecular polymers beyond the long-chain limit.

The optical activity of helical homopolymers devoid of chiral centers increases drastically when a small amount of homochiral monomers is incorporated into them. We study this so-called sergeants-and-soldiers effect of chirality amplification in solutions of helical supramolecular polymers with...
