In vivo imaging reveals rapid astrocyte depletion and axon damage in a model of neuromyelitis optica-related pathology.

Annals of neurology

Herwerth M, Kalluri SR, Srivastava R, Kleele T, Kenet S, Illes Z, Merkler D, Bennett JL, Misgeld T, Hemmer B.
PMID: 26946517
Ann Neurol. 2016 May;79(5):794-805. doi: 10.1002/ana.24630. Epub 2016 Apr 18.

OBJECTIVE: Neuromyelitis optica (NMO) is an autoimmune disease of the central nervous system, which resembles multiple sclerosis (MS). NMO differs from MS, however, in the distribution and histology of neuroinflammatory lesions and shows a more aggressive clinical course. Moreover,...

Nanoindentation of hcp metals: a comparative simulation study of the evolution of dislocation networks.

Nanotechnology

Alhafez IA, Ruestes CJ, Gao Y, Urbassek HM.
PMID: 26655887
Nanotechnology. 2016 Jan 29;27(4):045706. doi: 10.1088/0957-4484/27/4/045706. Epub 2015 Dec 14.

Using molecular dynamics simulation, we study the nanoindentation of three hcp metals: Mg, Ti, and Zr. Both the basal and two prismatic surface planes are considered. We focus on the characterization of the plasticity generated in the crystal. The...

The elastic-plastic transition in nanoparticle collisions.

Physical chemistry chemical physics : PCCP

Millán EN, Tramontina DR, Urbassek HM, Bringa EM.
PMID: 26456630
Phys Chem Chem Phys. 2016 Feb 07;18(5):3423-9. doi: 10.1039/c5cp05150a.

When nanoparticles (NPs) collide with low velocities, they interact elastically in the sense that--besides their fusion caused by their mutual van-der-Waals attraction--no defects are generated. We investigate the minimum velocity, vc, necessary for generating defects and inducing plasticity in...

Overview, Definitions, and Goals for ASHA's Treatment Outcomes and Clinical Trials Activities (What Difference Do Outcome Data Make to You?).

Language, speech, and hearing services in schools

Baum HM.
PMID: 27764378
Lang Speech Hear Serv Sch. 1998 Oct 01;29(4):246-249. doi: 10.1044/0161-1461.2904.246.

This article examines differences between efficacy and effectiveness, describes two research designs related to measuring efficacy and effectiveness, and describes the American Speech-Language-Hearing Association's (ASHA's) efforts relative to these research designs, with examples presented for how each of these...

Metallosis following a dual coat porous hydroxyapatite shoulder hemiarthroplasty.

Journal of orthopaedics

Khan H, Hurworth M, Kop A.
PMID: 26566331
J Orthop. 2015 Mar 12;12(4):266-71. doi: 10.1016/j.jor.2015.02.005. eCollection 2015 Dec.

We report a case of metallosis following a shoulder hemiarthroplasty with a humeral component resurfacing shoulder replacement.

A survey for isoenzymes of glucosephosphate isomerase, phosphoglucomutase, glucose-6-phosphate dehydrogenase and 6-Phosphogluconate dehydrogenase in C3-, C 4-and crassulacean-acid-metabolism plants, and green algae.

Planta

Herbert M, Burkhard C, Schnarrenberger C.
PMID: 24317570
Planta. 1979 Jan;145(1):95-104. doi: 10.1007/BF00379933.

Two isoenzymes each of glucosephosphate isomerase (EC 5.3.1.9), phosphoglucomutase (EC 2.7.5.1), glucose-6-phosphate dehydrogenase (EC 1.1.1.49) and 6-phosphogluconate dehydrogenase (EC 1.1.1.43) were separated by (NH4)2SO4 gradient solubilization and DEAE-cellulose ion-exchange chromatography from green leaves of the C3-plants spinach (Spinacia oleracea...

Contact angle of sessile drops in Lennard-Jones systems.

Langmuir : the ACS journal of surfaces and colloids

Becker S, Urbassek HM, Horsch M, Hasse H.
PMID: 25329011
Langmuir. 2014 Nov 18;30(45):13606-14. doi: 10.1021/la503974z. Epub 2014 Nov 05.

Molecular dynamics simulations are used for studying the contact angle of nanoscale sessile drops on a planar solid wall in a system interacting via the truncated and shifted Lennard-Jones potential. The entire range between total wetting and dewetting is...

Synthesis of homoallyl ethers via allylation of acetals in ionic liquids catalyzed by trimethylsilyl trifluoromethanesulfonate.

Organic letters

Zerth HM, Leonard NM, Mohan RS.
PMID: 12509889
Org Lett. 2003 Jan 09;5(1):55-7. doi: 10.1021/ol0271739.

The chemoselective allylation of acetals using allyltrimethylsilane in ionic liquids is catalyzed by TMS triflate (5.0-20.0 mol %). The reaction proceeds smoothly at room temperature to afford the corresponding homoallyl ether in good yield. Since the ionic liquids are...
