Subtle increases in heart size persist into adulthood in growth restricted babies: the Cardiovascular Risk in Young Finns Study.

Open heart

Arnott C, Skilton MR, Ruohonen S, Juonala M, Viikari JS, Kähönen M, Lehtimäki T, Laitinen T, Celermajer DS, Raitakari OT.
PMID: 26339495

BACKGROUND AND OBJECTIVES: Impaired fetal growth is associated with increased cardiovascular morbidity and mortality in adulthood. We sought to determine whether adults born with intrauterine growth restriction have primary maladaptive changes in cardiac structure.METHODS: Study participants were adults (34-49...

Neuropsychobiology. 2016;74(4):202-206. doi: 10.1159/000477247. Epub 2017 Jun 22.

BACKGROUND AND AIM: Seasonal patterns of food intake are found in healthy individuals and particularly in patients with seasonal affective disorder (SAD). One nutritional choice is a vegetarian diet.METHODS: In a Finnish population study, FINRISK 2012, information about diet...

Open-Ended Coaxial Dielectric Probe Effective Penetration Depth Determination.

IEEE transactions on microwave theory and techniques

Meaney PM, Gregory AP, Seppälä J, Lahtinen T.
PMID: 27346890
IEEE Trans Microw Theory Tech. 2016 Mar;64(3):915-923. doi: 10.1109/TMTT.2016.2519027. Epub 2016 Jan 29.

We have performed a series of experiments which demonstrate the effect of open-ended coaxial diameter on the depth of penetration. We used a two layer configuration of a liquid and movable cylindrical piece of either Teflon or acrylic. The...

Generation of nearly 3D-unpolarized evanescent optical near fields using total internal reflection.

Optics letters

Hassinen T, Popov S, Friberg AT, Setälä T.
PMID: 27367071
Opt Lett. 2016 Jul 01;41(13):2942-5. doi: 10.1364/OL.41.002942.

We analyze the time-domain partial polarization of optical fields composed of two evanescent waves created in total internal reflection by random electromagnetic beams with orthogonal planes of incidence. We show that such a two-beam configuration enables to generate nearly...

Diffusion tensor imaging detects chronic microstructural changes in white and gray matter after traumatic brain injury in rat.

Frontiers in neuroscience

PMID: 25954146
Front Neurosci. 2015 Apr 22;9:128. doi: 10.3389/fnins.2015.00128. eCollection 2015.

Traumatic brain injury (TBI) is a major cause of disability and death in people of all ages worldwide. An initial brain injury caused by external mechanical forces triggers a cascade of tissue changes that lead to a wide spectrum...

Exploring the atomic structure of 1.8nm monolayer-protected gold clusters with aberration-corrected STEM.

Ultramicroscopy

Liu J, Jian N, Ornelas I, Pattison AJ, Lahtinen T, Salorinne K, Häkkinen H, Palmer RE.
PMID: 28342572
Ultramicroscopy. 2017 May;176:146-150. doi: 10.1016/j.ultramic.2016.11.021. Epub 2016 Nov 22.

Monolayer-protected (MP) Au clusters present attractive quantum systems with a range of potential applications e.g. in catalysis. Knowledge of the atomic structure is needed to obtain a full understanding of their intriguing physical and chemical properties. Here we employed...

Characterization of polyesters prepared from three different phthalic acid isomers by CID-ESI-FT-ICR and PSD-MALDI-TOF mass spectrometry.

Analytical chemistry

Laine O, Laitinen T, Vainiotalo P.
PMID: 12199599
Anal Chem. 2002 Aug 15;74(16):4250-8. doi: 10.1021/ac0112566.

Polyesters prepared from the same diol, 2-butyl-2-ethyl-1,3-propanediol, but different phthalic acid isomers, phthalic, isophthalic, and terephthalic acid, were characterized by collision-induced dissociation electrospray ionization Fourier transform ion cyclotron resonance (CID-ESI-FT-ICR) and postsource-decay matrix-assisted laser desorption/ionization time-of-flight (PSD-MALDI-TOF) mass spectrometry....

Actigraphic recording of manic symptoms induced by methylphenidate.

Case reports in medicine

Lahti T, Leppämäki S, Tani P, Partonen T.
PMID: 19841753
Case Rep Med. 2009;2009:286430. doi: 10.1155/2009/286430. Epub 2009 Oct 15.

Objective. Attention-deficit hyperactivity disorder (ADHD) is a developmental disorder characterized by a long-standing pattern of impulsive behavior, hyperkinesia, and inattention. Psychostimulants, for example, methylphenidate, are the treatment of choice for ADHD both in children, adolescents, and adults. Method. The...

Cross-spectral purity of electromagnetic fields.

Optics letters

Hassinen T, Tervo J, Friberg AT.
PMID: 20016640
Opt Lett. 2009 Dec 15;34(24):3866-8. doi: 10.1364/OL.34.003866.

We extend Mandel's scalar-wave concept of cross-spectral purity to electromagnetic fields. We show that in the electromagnetic case, assumptions similar to the scalar cross-spectral purity lead to a reduction formula, analogous with the one introduced by Mandel. We also...

N-Benzyl-2,3,4,5,6-penta-fluoro-benz-amide.

Acta crystallographica. Section E, Structure reports online
