Adaptive potential of ash (Fraxinus excelsior) populations against the novel emerging pathogen Hymenoscyphus pseudoalbidus.

Evolutionary applications

Kjær ED, McKinney LV, Nielsen LR, Hansen LN, Hansen JK.
PMID: 25568043
Evol Appl. 2012 Apr;5(3):219-28. doi: 10.1111/j.1752-4571.2011.00222.x. Epub 2011 Dec 03.

An emerging infectious pathogen Hymenoscyphus pseudoalbidus has spread across much of Europe within recent years causing devastating damage on European common ash trees (Fraxinus excelsior) and associated plant communities. The present study demonstrates the presence of additive genetic variation...

Kjær B, Scheller HV.
PMID: 24301705
Photosynth Res. 1996 Jan;47(1):33-9. doi: 10.1007/BF00017751.

Chlorosome-depleted membranes and a reaction center complex with well-defined subunit composition were prepared from the green sulfur bacterium Chlorobium vibrioforme under anaerobic conditions. The reaction center complex contains a 15-kDa polypeptide with the N-terminal amino acid sequence MEPQLSRPETASNQVR/. This...

Positron emission tomography in the follow-up of cutaneous malignant melanoma patients: a systematic review.

American journal of nuclear medicine and molecular imaging

Danielsen M, Højgaard L, Kjær A, Fischer BM.
PMID: 24380042
Am J Nucl Med Mol Imaging. 2013 Dec 15;4(1):17-28.

Cutaneous malignant melanoma (CMM) has a high risk of dissemination to regional lymph nodes and visceral organs. Recurrences are most frequently seen within the first 2-3 years after initial treatment, but these patients have a life-long risk of relapse....

Global solar radiation as the factor controlling induction of diapause in the pod midge (Dasyneura brassicae Winn.).

Oecologia

Axelsen JA, Fink R, Kjær C.
PMID: 28307992
Oecologia. 1997 Jul;111(2):178-182. doi: 10.1007/s004420050223.

In this paper we examine the hypothesis that diapause induction in the polyvoltine pod midge Dasyneura brassicae Winn. (Diptera: Cecidomyiidae) is controlled by cumulative global solar radiation during the larval stage. The correlation between field observations of relative diapause...

Femtosecond X-Ray Scattering Study of Ultrafast Photoinduced Structural Dynamics in Solvated [Co(terpy)_{2}]^{2+}.

Phys Rev Lett. 2016 Jul 01;117(1):013002. doi: 10.1103/PhysRevLett.117.013002. Epub 2016 Jun 30.

We study the structural dynamics of photoexcited [Co(terpy)_{2}]^{2+} in an aqueous solution with ultrafast x-ray diffuse scattering experiments conducted at the Linac Coherent Light Source. Through direct comparisons with density functional theory calculations, our analysis shows that the photoexcitation...

Polyploidy can Confer Superiority to West African Acacia senegal (L.) Willd. Trees.

Frontiers in plant science

Diallo AM, Nielsen LR, Kjær ED, Petersen KK, Ræbild A.
PMID: 27379120
Front Plant Sci. 2016 Jun 14;7:821. doi: 10.3389/fpls.2016.00821. eCollection 2016.

Polyploidy is a common phenomenon in the evolution of angiosperms. It has been suggested that polyploids manage harsh environments better than their diploid relatives but empirical data supporting this hypothesis are scarce, especially for trees. Using microsatellite markers and...

Minimal residual disease after long-term interferon-alpha2 treatment: a report on hematological, molecular and histomorphological response patterns in 10 patients with essential thrombocythemia and polycythemia vera.

Leukemia & lymphoma

Utke Rank C, Weis Bjerrum O, Larsen TS, Kjær L, de Stricker K, Riley CH, Hasselbalch HC.
PMID: 25956046
Leuk Lymphoma. 2016 Feb;57(2):348-354. doi: 10.3109/10428194.2015.1049171. Epub 2015 Jun 18.

Essential thrombocythemia (ET) and polycythemia vera (PV) are Philadelphia chromosome-negative chronic myeloproliferative neoplasms (MPNs) characterized by the JAK2 V617F mutation, which can be found in more than 98% of PV patients and in ∼ 50% of ET patients. Assessment...

Impact of incorrect tissue classification in Dixon-based MR-AC: fat-water tissue inversion.

EJNMMI physics

Ladefoged CN, Hansen AE, Keller SH, Holm S, Law I, Beyer T, Højgaard L, Kjær A, Andersen FL.
PMID: 26501459
EJNMMI Phys. 2014 Dec;1(1):101. doi: 10.1186/s40658-014-0101-0. Epub 2014 Dec 14.

BACKGROUND: The current MR-based attenuation correction (AC) used in combined PET/MR systems computes a Dixon attenuation map (MR-ACDixon) based on fat and water images derived from in- and opposed-phase MRI. We observed an occasional fat/water inversion in MR-ACDixon. The...

Feasibility of simultaneous PET/MR in diet-induced atherosclerotic minipig: a pilot study for translational imaging.

American journal of nuclear medicine and molecular imaging

Novel hybrid 18-fluoro-deoxy-D-glucose ((18)F-FDG) based positron emission tomography (PET) and magnetic resonance imaging (MRI) has shown promise for characterization of atherosclerotic plaques clinically. The purpose of this study was to evaluate the method in a pre-clinical model of diet-induced...

Journal of nematology

Nielsen EL, Baltensperger DD, Kerr ED, Rife CL.
PMID: 19265972
