Single-nanoparticle detection using a low-aspect-ratio pore.

ACS nano

Tsutsui M, Hongo S, He Y, Taniguchi M, Gemma N, Kawai T.
PMID: 22424475
ACS Nano. 2012 Apr 24;6(4):3499-505. doi: 10.1021/nn300530b. Epub 2012 Mar 21.

We explored single-particle translocation through a low thickness-to-diameter aspect ratio Si(3)N(4) pore mimicking graphene nanopore structure by a resistive pulse method. Ionic conductance of 0.05 aspect ratio pores scales linearly with the diameter, indicating predominant contribution of the access...

Applied animal behaviour science

Miller AL, Kitson GL, Skalkoyannis B, Flecknell PA, Leach MC.
PMID: 27499567
Appl Anim Behav Sci. 2016 Aug;181:160-165. doi: 10.1016/j.applanim.2016.05.020.

Mice used in biomedical research should have pain reduced to an absolute minimum through refinement of procedures or by the provision of appropriate analgesia. Vasectomy is a common and potentially painful surgical procedure carried out on male mice to...

A case of anti-aminoacyl tRNA synthetase (ARS) antibody-positive polymyositis (PM)/dermatomyositis (DM)-associated interstitial pneumonia (IP) successfully controlled with bosentan therapy.

A 72-year-old woman was admitted to our hospital and was diagnosed with interstitial pneumonia (IP) associated with amyopathic dermatomyositis (ADM). The patient experienced three acute IP exacerbations in the 7 years that followed, which were each treated and resolved...

Chemical and biological assessment of metal organic frameworks (MOFs) in pulmonary cells and in an acute in vivo model: relevance to pulmonary arterial hypertension therapy.

Pulmonary circulation

Mohamed NA, Davies RP, Lickiss PD, Ahmetaj-Shala B, Reed DM, Gashaw HH, Saleem H, Freeman GR, George PM, Wort SJ, Morales-Cano D, Barreira B, Tetley TD, Chester AH, Yacoub MH, Kirkby NS, Moreno L, Mitchell JA.

Pulm Circ. 2017 Jul-Sep;7(3):643-653. doi: 10.1177/2045893217710224. Epub 2017 Jun 27.

Pulmonary arterial hypertension (PAH) is a progressive and debilitating condition. Despite promoting vasodilation, current drugs have a therapeutic window within which they are limited by systemic side effects. Nanomedicine uses nanoparticles to improve drug delivery and/or reduce side effects....

Chutia A, Gibson EK, Farrow MR, Wells PP, Scanlon DO, Dimitratos N, Willock DJ, Catlow CRA.
PMID: 28926035
Phys Chem Chem Phys. 2017 Oct 18;19(40):27191-27203. doi: 10.1039/c7cp04144f.

We report a detailed density functional theory (DFT) study in conjunction with extended X-ray absorption fine structure (EXAFS) experiments on the geometrical and local electronic properties of Cu adatoms and Cu(ii) ions in presence of water molecules and of...

Single-molecule electronics: Cooling individual vibrational modes by the tunneling current.

The Journal of chemical physics

Lykkebo J, Romano G, Gagliardi A, Pecchia A, Solomon GC.
PMID: 27004879
J Chem Phys. 2016 Mar 21;144(11):114310. doi: 10.1063/1.4943578.

Electronic devices composed of single molecules constitute the ultimate limit in the continued downscaling of electronic components. A key challenge for single-molecule electronics is to control the temperature of these junctions. Controlling heating and cooling effects in individual vibrational...

Close relation between quantum interference in molecular conductance and diradical existence.

Proceedings of the National Academy of Sciences of the United States of America

Tsuji Y, Hoffmann R, Strange M, Solomon GC.
PMID: 26755578
Proc Natl Acad Sci U S A. 2016 Jan 26;113(4):E413-9. doi: 10.1073/pnas.1518206113. Epub 2016 Jan 11.

An empirical observation of a relationship between a striking feature of electronic transmission through a π-system, destructive quantum interference (QI), on one hand, and the stability of diradicals on the other, leads to the proof of a general theorem...

Understanding the length dependence of molecular junction thermopower.

The Journal of chemical physics

Karlström O, Strange M, Solomon GC.
PMID: 25669531
J Chem Phys. 2014 Jan 28;140(4):044315. doi: 10.1063/1.4862905.

Thermopower of molecular junctions is sensitive to details in the junction and may increase, decrease, or saturate with increasing chain length, depending on the system. Using McConnell's theory for exponentially suppressed transport together with a simple and easily interpretable...

Oncoimmunology. 2015 Feb 25;4(2):e981457. doi: 10.4161/2162402X.2014.981457. eCollection 2015 Feb.

The expression of the immunomodulating enzyme indoleamine-2,3-dioxygenase (IDO) suppresses T-lymphocyte function, thus correlating with poor survival in a variety of cancer patients. IDO degrades the essential amino acid tryptophan leading to immunosuppressive kynurenines production. In the present study, concentrations...
