Maternal effects in vulnerability to eye-parasites and correlations between behavior and parasitism in juvenile Arctic charr.

Ecology and evolution

Kortet R, Lautala T, Kekäläinen J, Taskinen J, Hirvonen H.
PMID: 29152177
Ecol Evol. 2017 Sep 18;7(21):8780-8787. doi: 10.1002/ece3.3428. eCollection 2017 Nov.

Hatchery-reared fish show high mortalities after release to the wild environment. Explanations for this include potentially predetermined genetics, behavioral, and physiological acclimation to fish farm environments, and increased vulnerability to predation and parasitism in the wild. We studied vulnerability...

Dirty limit scattering behind the decreased anisotropy of doped YBa2Cu3O7-δ thin films.

Malmivirta M, Palonen H, Inkinen S, Yao LD, Tikkanen J, Huhtinen H, Jha R, Awana VP, van Dijken S, Paturi P.
PMID: 27046012
J Phys Condens Matter. 2016 May 05;28(17):175702. doi: 10.1088/0953-8984/28/17/175702. Epub 2016 Apr 05.

We measured the resistivity of pulsed-laser-deposited BaCeO3 (BCO)-doped YBCO thin films containing spherical BCO particles in fields up to 30 T. The average diameter of the particles depends on the dopant concentration being below 4 nm in all the...

Effect of starvation on parasite-induced mortality in a freshwater snail (Potamopyrgus antipodarum).

Oecologia

Jokela J, Lively CM, Taskinen J, Peters AD.
PMID: 28307754
Oecologia. 1999 May;119(3):320-325. doi: 10.1007/s004420050792.

The level of host exploitation is expected, under theory, to be selected to maximise (subject to constraints) the lifetime reproductive success of the parasite. Here we studied the effect of two castrating trematode species on their intermediate snail host,...

[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...

Mechanically robust superhydrophobic polymer surfaces based on protective micropillars.

Langmuir : the ACS journal of surfaces and colloids

Huovinen E, Takkunen L, Korpela T, Suvanto M, Pakkanen TT, Pakkanen TA.
PMID: 24483340
Langmuir. 2014 Feb 11;30(5):1435-43. doi: 10.1021/la404248d. Epub 2014 Jan 31.

Considerable attention is currently being devoted less to the question of whether it is possible to produce superhydrophobic polymer surfaces than to just how robust they can be made. The present study demonstrates a new route for improving the...

Production of a recombinant antibody specific for i blood group antigen, a mesenchymal stem cell marker.

Biores Open Access. 2013 Oct;2(5):336-45. doi: 10.1089/biores.2013.0026.

Multipotent mesenchymal stem/stromal cells (MSCs) offer great promise for future regenerative and anti-inflammatory therapies. Panels of functional and phenotypical markers are currently used in characterization of different therapeutic stem cell populations from various sources. The i antigen (linear poly-N-acetyllactosamine)...

An illustrated key to the cuckoo wasps (Hymenoptera, Chrysididae) of the Nordic and Baltic countries, with description of a new species.

ZooKeys

Paukkunen J, Berg A, Soon V, Ødegaard F, Rosa P.
PMID: 26798322
Zookeys. 2015 Dec 23;(548):1-116. doi: 10.3897/zookeys.548.6164. eCollection 2015.

The Chrysididae are a group of cleptoparasitic and parasitoid aculeate wasps with a large number of rare and endangered species. The taxonomy of this group has long been confusing due to the similarity of species and extensive intraspecific variation....

The duration of exposure to 50 Hz magnetic fields: Influence on circadian genes and DNA damage responses in murine hematopoietic FDC-P1 cells.

We investigated the effects of 50 Hz extremely low-frequency magnetic fields (MFs) on gene expression related to the circadian rhythm or DNA damage signaling and whether these fields modify DNA damage repair rate after bleomycin treatment. Murine FDC-P1 hematopoietic...

Challenging Management of Plexiform Schwannoma and Plexiform Neurofibroma.

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....
