Insight to Nanoparticle Size Analysis-Novel and Convenient Image Analysis Method Versus Conventional Techniques.

Nanoscale research letters

Vippola M, Valkonen M, Sarlin E, Honkanen M, Huttunen H.
PMID: 27030469
Nanoscale Res Lett. 2016 Dec;11(1):169. doi: 10.1186/s11671-016-1391-z. Epub 2016 Mar 31.

The aim of this paper is to introduce a new image analysis program "Nanoannotator" particularly developed for analyzing individual nanoparticles in transmission electron microscopy images. This paper describes the usefulness and efficiency of the program when analyzing nanoparticles, and...

Participatory operations model for cost-efficient monitoring and modeling of river basins--A systematic approach.

Inflammatory responses in RAW264.7 macrophages caused by mycobacteria isolated from moldy houses.

Environmental toxicology and pharmacology

Huttunen K, Ruotsalainen M, Iivanainen E, Torkko P, Katila M, Hirvonen M.
PMID: 10996543
Environ Toxicol Pharmacol. 2000 Jun 01;8(4):237-244. doi: 10.1016/s1382-6689(00)00047-8.

Mycobacterial strains (nonpathogenic Mycobacterium terrae, potentially pathogenic Mycobacterium avium-complex and Mycobacterium scrofulaceum), isolated from a moldy building, were studied with respect to their ability to stimulate macrophages (RAW264.7) to produce inflammatory mediators, and to cause cytotoxicity. Reactive oxygen species...

Peripheral tissue energy metabolism during recovery from hypothermia after cardiopulmonary bypass: effect of amino-acid infusions.

Clinical nutrition (Edinburgh, Scotland)

Hersio K, Takala J, Kari A, Huttunen K.
PMID: 16839891
Clin Nutr. 1991 Feb;10(1):30-5. doi: 10.1016/0261-5614(91)90078-q.

We studied the effects of amino-acid administration on the leg exchange of energy substrates and amino-acids during recovery from hypothermia after open heart surgery. Glucose (G, n = 5), glucose and conventional amino-acids (CA, n = 5) or glucose...

Tip-enhanced Raman scattering from bridged nanocones.

Optics express

Rao S, Huttunen MJ, Kontio JM, Makitalo J, Viljanen MR, Simonen J, Kauranen M, Petrov D.
PMID: 21164723
Opt Express. 2010 Nov 08;18(23):23790-5. doi: 10.1364/OE.18.023790.

We present two silver nanocones separated by 450 nm, well beyond the typical gap spacing of coupled nanoantennas, and connected by a metal bridge to facilitate plasmonic coupling between them. The tip-enhanced Raman scattering from crystal violet molecules is...

Do elevations in temperature, CO2, and nutrient availability modify belowground carbon gain and root morphology in artificially defoliated silver birch seedlings?.

Ecology and evolution

Huttunen L, Saravesi K, Markkola A, Niemelä P.
PMID: 24101972
Ecol Evol. 2013 Sep;3(9):2783-94. doi: 10.1002/ece3.665. Epub 2013 Jul 22.

Climate warming increases the risk of insect defoliation in boreal forests. Losses in photosynthetically active surfaces cause reduction in net primary productivity and often compromise carbon reserves of trees. The concurrent effects of climate change and removal of foliage...

Non-Steroidal Biphenyl Gelators: Correlation of Xerogel Structure with Solid-State Structure and Circular Dichroism Spectroscopy.

Gels (Basel, Switzerland)

Geiger HC, Geiger DK, Roberts WR, Morell DL, Huttunen P, Schulman JL, Tran M, Farthing D.
PMID: 30674810
Gels. 2018 Apr 16;4(2). doi: 10.3390/gels4020034.

Because the factors favoring the formation of well-formed single crystals are dissimilar to those conducive to gel formation, few examples of single-crystal structural characterizations of organogelators are found in the literature. A series of biphenyl methyl and ethyl diester...
