Diagnostic efficiency of the Rorschach schizophrenia and depression indices in identifying first-episode schizophrenia and severe depression.

Psychiatry research

Ilonen T, Taiminen T, Karlsson H, Lauerma H, Leinonen KM, Wallenius E, Tuimala P, Salokangas RK.
PMID: 10579551
Psychiatry Res. 1999 Oct 11;87(2):183-92. doi: 10.1016/s0165-1781(99)00061-x.

We studied the diagnostic efficiency of the Rorschach schizophrenia (SCZI) and depression (DEPI) indices for detecting first-episode schizophrenia and severe depression with and without psychotic features using DSM-IV as a gold standard measure. Twenty-seven patients with first-episode schizophrenia, 13...

Corrections to linear methods for diffuse optical tomography using approximation error modelling.

Biomedical optics express

Tarvainen T, Kolehmainen V, Kaipio JP, Arridge SR.
PMID: 21258459
Biomed Opt Express. 2010 Jul 16;1(1):209-222. doi: 10.1364/BOE.1.000209.

Linear reconstruction methods in diffuse optical tomography have been found to produce reasonable good images in cases in which the variation in optical properties within the medium is relatively small and a reference measurement with known background optical properties...

Compensation of optode sensitivity and position errors in diffuse optical tomography using the approximation error approach.

Biomedical optics express

Mozumder M, Tarvainen T, Arridge SR, Kaipio J, Kolehmainen V.
PMID: 24156061
Biomed Opt Express. 2013 Sep 06;4(10):2015-31. doi: 10.1364/BOE.4.002015. eCollection 2013.

Diffuse optical tomography is highly sensitive to measurement and modeling errors. Errors in the source and detector coupling and positions can cause significant artifacts in the reconstructed images. Recently the approximation error theory has been proposed to handle modeling...

Stimuli-Responsive Nanodiamond-Polyelectrolyte Composite Films.

Polymers

Tiainen T, Lobanova M, Karjalainen E, Tenhu H, Hietala S.
PMID: 32110929
Polymers (Basel). 2020 Feb 26;12(3). doi: 10.3390/polym12030507.

Nanodiamonds (NDs) can considerably improve the mechanical and thermal properties of polymeric composites. However, the tendency of NDs to aggregate limits the potential of these non-toxic, mechanically- and chemically-robust nanofillers. In this work, tough, flexible, and stimuli-responsive polyelectrolyte films...

Pediatr Nephrol. 2021 Aug 16; doi: 10.1007/s00467-021-05227-0. Epub 2021 Aug 16.

BACKGROUND: Hypotonic fluids have been associated with hospital-acquired hyponatremia. The incidence of life-threatening severe hyponatremia associated with hypotonic fluids has not been evaluated.METHODS: This was a population-based cohort study of 46,518 acutely ill children 15 years of age or...

OBJECTIVE: To describe the diagnostic utility of whole-genome sequencing and RNA studies in boys with suspected dystrophinopathy, for whom multiplex ligation-dependent probe amplification and exomic parallel sequencing failed to yield a genetic diagnosis, and to use remnant normal METHODS:...

Vertical Transmission of Gut Microbiome and Antimicrobial Resistance Genes in Infants Exposed to Antibiotics at Birth.

The Journal of infectious diseases

Li W, Tapiainen T, Brinkac L, Lorenzi HA, Moncera K, Tejesvi MV, Salo J, Nelson KE.
PMID: 32239170
J Infect Dis. 2021 Oct 13;224(7):1236-1246. doi: 10.1093/infdis/jiaa155.

Vertical transmission of maternal microbes is a major route for establishing the gut microbiome in newborns. The impact of perinatal antibiotics on vertical transmission of microbes and antimicrobial resistance is not well understood. Using a metagenomic approach, we analyzed...
