Polarized backscattering by clusters of spherical particles.

Optics letters

Virkki A, Markkanen J, Tyynelä J, Peltoniemi JI, Muinonen K.
PMID: 26258383
Opt Lett. 2015 Aug 01;40(15):3663-6. doi: 10.1364/OL.40.003663.

The linear and circular polarization ratios for clusters of spherical particles averaged over multiple orientations show a systematic pattern as a function of the refractive index and the size parameter. We show that, at backscattering, the depolarizing behavior of...

[Neck lump--fine-needle aspiration biopsy specimen in diagnostics and planning of therapy].

Duodecim; laaketieteellinen aikakauskirja

Atula T, Tarkkanen J, Aro K.
PMID: 25558601
Duodecim. 2014;130(22):2405-12.

In elucidating the cause of a non-tender neck lump, the age of the patient, location and finding on palpation of lumps, and clinical examination of ear, nose and throat disorders and possible other findings are crucial. Fine-needle aspiration biopsy...

On-line monitoring of continuous beer fermentation process using automatic membrane inlet mass spectrometric system.

Talanta

Tarkiainen V, Kotiaho T, Mattila I, Virkajärvi I, Aristidou A, Ketola RA.
PMID: 18969939
Talanta. 2005 Mar 15;65(5):1254-63. doi: 10.1016/j.talanta.2004.08.051.

A fully automatic membrane inlet mass spectrometric (MIMS) on-line instrumentation for the analysis of aroma compounds in continuous beer fermentation processes was constructed and tested. The instrumentation includes automatic filtration of the sample stream, flushing of all tubing between...

Escherichia coli plasmid production in fermenter.

Biotechnology and bioengineering

Reinikainen P, Korpela K, Nissinen V, Olkku J, Söderlund H, Markkanen P.
PMID: 18587929
Biotechnol Bioeng. 1989 Jan 20;33(4):386-93. doi: 10.1002/bit.260330403.

Escherichia coli harboring a recombinant plasmid was grown in a fermenter to study the effects of selected process parameters on the growth of the microbe and on plasmid amplification with chloramphenicol treatment. Eighteen fermentations were carried out according to...

Challenging Management of Plexiform Schwannoma and Plexiform Neurofibroma.

The Journal of craniofacial surgery

Nicoli TK, Saat R, Tarkkanen J, Kinnunen I, Mäkitie AA, Jero J.
PMID: 34855632
J Craniofac Surg. 2021 Dec 02; doi: 10.1097/SCS.0000000000008381. Epub 2021 Dec 02.

ABSTRACT: Plexiform variants of neurofibromas and schwannomas are rare and typically arise in superficial soft tissues in the head and neck region. The treatment of these tumors is challenging and no generally accepted guidelines exist for their optimal management....

Homogeneous nucleation of carbon dioxide in supersonic nozzles II: molecular dynamics simulations and properties of nucleating clusters.

Physical chemistry chemical physics : PCCP

Halonen R, Tikkanen V, Reischl B, Dingilian KK, Wyslouzil BE, Vehkamäki H.
PMID: 33595558
Phys Chem Chem Phys. 2021 Feb 28;23(8):4517-4529. doi: 10.1039/d0cp05653g. Epub 2021 Feb 17.

Large scale molecular dynamics simulations of the homogeneous nucleation of carbon dioxide in an argon atmosphere were carried out at temperatures between 75 and 105 K. Extensive analyses of the nucleating clusters' structural and energetic properties were performed to...

Measuring DNA Damage Using the Alkaline Comet Assay in Cultured Cells.

Bio-protocol

Clementi E, Garajova Z, Markkanen E.
PMID: 34541038
Bio Protoc. 2021 Aug 20;11(16):e4119. doi: 10.21769/BioProtoc.4119. eCollection 2021 Aug 20.

Maintenance of DNA integrity is of pivotal importance for cells to circumvent detrimental processes that can ultimately lead to the development of various diseases. In the face of a plethora of endogenous and exogenous DNA-damaging agents, cells have evolved...

Scattering of light by a large, densely packed agglomerate of small silica spheres.

Optics letters

Väisänen T, Markkanen J, Hadamcik E, Renard JB, Lasue J, Levasseur-Regourd AC, Blum J, Muinonen K.
PMID: 32235972
Opt Lett. 2020 Apr 01;45(7):1679-1682. doi: 10.1364/OL.382240.

We model the measured phase function and degree of linear polarization of a macroscopic agglomerate made of micrometer-scale silica spheres using the methodology of multiple scattering. In the laboratory work, the agglomerate is produced ballistically, characterized by scanning electron...

Stress and Tinnitus; Transcutaneous Auricular Vagal Nerve Stimulation Attenuates Tinnitus-Triggered Stress Reaction.

Frontiers in psychology

Ylikoski J, Markkanen M, Pirvola U, Lehtimäki JA, Ylikoski M, Jing Z, Sinkkonen ST, Mäkitie A.
