OBJECTIVE: The aim of this study was to analyze brain pathologies which cause dementia in the oldest old population.METHODS: All 601 persons aged ≥85 years living in the city of Vantaa (Finland), on April 1st, 1991 formed the study...

Diagnosis of Knee Osteochondral Lesions With Ultrasound Imaging.

Arthroscopy techniques

Arthrosc Tech. 2015 Sep 14;4(5):e429-33. doi: 10.1016/j.eats.2015.04.002. eCollection 2015 Oct.

Evaluation of articular cartilage and subchondral bone is essential in the diagnosis of joint diseases and injuries. Interobserver and intraobserver reproducibilities of arthroscopic grading are only poor to moderate. Thus, for quantitative and objective evaluation of cartilage and subchondral...

Phys Rev Lett. 2008 Aug 01;101(5):052502. doi: 10.1103/PhysRevLett.101.052502. Epub 2008 Jul 31.

Atomic masses of the neutron-rich isotopes (76-80)Zn, (78-83)Ga, (80-85)Ge, (81-87)As, and (84-89)Se have been measured with high precision using the Penning trap mass spectrometer JYFLTRAP at the IGISOL facility. The masses of (82,83)Ga, (83-85)Ge, (84-87)As, and 89Se were measured...

Neutron beam effects on spin-exchange-polarized 3He.

Physical review letters

Sharma M, Babcock E, Andersen KH, Barrón-Palos L, Becker M, Boag S, Chen WC, Chupp TE, Danagoulian A, Gentile TR, Klein A, Penttila S, Petoukhov A, Soldner T, Tardiff ER, Walker TG, Wilburn WS.

Phys Rev Lett. 2008 Aug 22;101(8):083002. doi: 10.1103/PhysRevLett.101.083002. Epub 2008 Aug 20.

We have observed depolarization effects when high intensity cold neutron beams are incident on alkali-metal spin-exchange-polarized 3He cells used as neutron spin filters. This was first observed as a reduction of the maximum attainable 3He polarization and was attributed...

Aromatic fumaronitrile core-based donor-linker-acceptor-linker-donor (D-pi-A-pi-D) compounds: synthesis and photophysical properties.

The journal of physical chemistry. A

Panthi K, Adhikari RM, Kinstle TH.
PMID: 20235549
J Phys Chem A. 2010 Apr 08;114(13):4542-9. doi: 10.1021/jp9115589.

A new class of aromatic fumaronitrile core-based compounds with different donors and linkers has been synthesized and well characterized. Compounds 1 and 2 have indole and 2-phenylindole groups as electron donors, respectively. Compounds 3 and 4 have a diphenylamino...

Light-scattering efficiency of starch acetate pigments as a function of size and packing density.

Applied optics

Penttilä A, Lumme K, Kuutti L.
PMID: 16708095
Appl Opt. 2006 May 20;45(15):3501-9. doi: 10.1364/ao.45.003501.

We study theoretically the light-scattering efficiency of paper coatings made of starch acetate pigments. For the light-scattering code we use a discrete dipole approximation method. The coating layer is assumed to consists of roughly equal-sized spherical pigments packed either...

Chromosomal Integration and Expression of Two Bacterial alpha-Acetolactate Decarboxylase Genes in Brewer's Yeast.

Applied and environmental microbiology

Blomqvist K, Suihko ML, Knowles J, Penttilä M.
PMID: 16348559
Appl Environ Microbiol. 1991 Oct;57(10):2796-803. doi: 10.1128/aem.57.10.2796-2803.1991.

A bacterial gene encoding alpha-acetolactate decarboxylase, isolated from Klebsiella terrigena or Enterobacter aerogenes, was expressed in brewer's yeast. The genes were expressed under either the yeast phosphoglycerokinase (PGK1) or the alcohol dehydrogenase (ADH1) promoter and were integrated by gene...

Attrition in a 30-year follow-up of a perinatal birth risk cohort: factors change with age.

PeerJ

Launes J, Hokkanen L, Laasonen M, Tuulio-Henriksson A, Virta M, Lipsanen J, Tienari PJ, Michelsson K.

Background. Attrition is a major cause of potential bias in longitudinal studies and clinical trials. Attrition rate above 20% raises concern of the reliability of the results. Few studies have looked at the factors behind attrition in follow-ups spanning...
