Changes in neurophysiologic markers of visual processing following beneficial anti-VEGF treatment in macular degeneration.

Clinical ophthalmology (Auckland, N.Z.)

Vottonen P, Kaarniranta K, Pääkkönen A, Tarkka IM.
PMID: 23467427
Clin Ophthalmol. 2013;7:437-42. doi: 10.2147/OPTH.S40427. Epub 2013 Feb 27.

PURPOSE: Antivascular endothelial growth factor (VEGF) agents have been shown to improve visual acuity and prevent vision loss in exudative age-related macular degeneration. As the vision improves relatively quickly in response to intravitreal injections, we wanted to know whether...

Crossover from mean-field compression to collective phenomena in low-density foam-formed fiber material.

Soft matter

Mäkinen T, Koivisto J, Pääkkönen E, Ketoja JA, Alava MJ.
PMID: 32632431
Soft Matter. 2020 Aug 07;16(29):6819-6825. doi: 10.1039/d0sm00286k. Epub 2020 Jul 07.

We study the compression of low-weight foam-formed materials made out of wood fibers. Initially the stress-strain behavior follows mean-field like response, related to the buckling of fiber segments as dictated by the random three-dimensional geometry. Our Acoustic Emission (AE)...
