Seydou F, Ramahi OM, Duraiswami R, Seppänen T.
PMID: 19529554
Opt Express. 2006 Nov 13;14(23):11362-71. doi: 10.1364/oe.14.011362.

We develop a numerical algorithm that computes the Green's function of Maxwell equation for a 2D finite-size photonic crystal, composed of rods of arbitrary shape. The method is based on the boundary integral equation, and a Nyström discretization is...

MicroRNAs regulate osteogenesis and chondrogenesis of mouse bone marrow stromal cells.

Gene regulation and systems biology

Suomi S, Taipaleenmäki H, Seppänen A, Ripatti T, Väänänen K, Hentunen T, Säämänen AM, Laitala-Leinonen T.
PMID: 19787082
Gene Regul Syst Bio. 2008 Apr 22;2:177-91. doi: 10.4137/grsb.s662.

MicroRNAs (miRNAs) are non-coding RNAs that bind to target mRNA leading to translational arrest or mRNA degradation. To study miRNA-mediated regulation of osteogenesis and chondrogenesis, we compared the expression of 35 miRNAs in osteoblasts and chondroblasts derived from mouse...

Development of a method to compensate for signal quality variations in repeated auditory event-related potential recordings.

Frontiers in neuroengineering

Paukkunen AK, Leminen MM, Sepponen R.
PMID: 20407635
Front Neuroeng. 2010 Mar 16;3:2. doi: 10.3389/fneng.2010.00002. eCollection 2010.

Reliable measurements are mandatory in clinically relevant auditory event-related potential (AERP)-based tools and applications. The comparability of the results gets worse as a result of variations in the remaining measurement error. A potential method is studied that allows optimization...

Front Public Health. 2014 Apr 07;2:26. doi: 10.3389/fpubh.2014.00026. eCollection 2014.

In many economically struggling societies, forensic psychiatry is still in its initial developmental stages and thus forensic patients pose an ongoing challenge for the healthcare and juridical systems. In this article, we present the various issues and problems that...

In Crohn's Disease, Anti-TNF-α Treatment Changes the Balance between Mucosal IL-17, FOXP3, and CD4 Cells.

Aim. In Crohn's disease (CD), anti-TNF-α treatment is a potent medication. We aimed to characterize the effect of anti-TNF-α treatment on T effector and regulatory cells. Material and Methods. We studied T-effector and regulatory cells on cellular and mRNA...

Music training enhances rapid neural plasticity of n1 and p2 source activation for unattended sounds.

Frontiers in human neuroscience

Seppänen M, Hämäläinen J, Pesonen AK, Tervaniemi M.
PMID: 22435057
Front Hum Neurosci. 2012 Mar 14;6:43. doi: 10.3389/fnhum.2012.00043. eCollection 2012.

Neurocognitive studies have demonstrated that long-term music training enhances the processing of unattended sounds. It is not clear, however, whether music training also modulates rapid (within tens of minutes) neural plasticity for sound encoding. To study this phenomenon, we...

METHODS: NF-κB activation was studied in a mutation-expressing cell line using luciferase reporter assay. Physical and close-proximity protein-protein interactions of wild-type and RESULTS: The protein-protein interactome of p.(Lys91*) mutant A20 was severely impaired, including interactions with proteins regulating NF-κB...
