Role of intranasal fentanyl in breakthrough pain management in cancer patients.

Cancer management and research

Leppert W.
PMID: 21188114
Cancer Manag Res. 2010 Sep 30;2:225-32. doi: 10.2147/CMR.S7926.

Fentanyl is a strong opioid analgesic, which is commonly used in the form of a transdermal patch for the treatment of chronic cancer pain. An intranasal route of fentanyl administration is a novel treatment for breakthrough cancer pain (BTCP)....

Synthesis and magnetic characterization of MnAs nanoparticles via nanoparticle conversion.

Nanotechnology

Wolff MF, Görlitz D, Nielsch K, Messing ME, Deppert K.
PMID: 21178252
Nanotechnology. 2011 Feb 04;22(5):055602. doi: 10.1088/0957-4484/22/5/055602. Epub 2010 Dec 23.

We report on the synthesis of ferromagnetic manganese arsenide (MnAs) nanoparticles via the conversion of primary Mn particles which are generated in an aerosol process in a spark discharge generator. After sintering and size selection in an aerosol setup,...

Analytical formulas for low-fluence non-line-narrowed hole-burned spectra in an excitonically coupled dimer.

The Journal of chemical physics

Reppert M, Naibo V, Jankowiak R.
PMID: 20025311
J Chem Phys. 2009 Dec 21;131(23):234104. doi: 10.1063/1.3270394.

We present exact equations for the low-fluence non-line-narrowed (NLN) nonphotochemical hole-burning (NPHB) spectrum of an excitonically coupled dimer (for arbitrary coupling strength) under the assumption that postburn and preburn site energies are independent. The equations provide a transparent view...

Height-controlled nanowire branches on nanotrees using a polymer mask.

Nanotechnology

Dick KA, Deppert K, Larsson MW, Seifert W, Reine Wallenberg L, Samuelson L.
PMID: 19636124
Nanotechnology. 2007 Jan 24;18(3):035601. doi: 10.1088/0957-4484/18/3/035601. Epub 2007 Jan 03.

The production of complex three-dimensional dendritic structures is an important step in the application of semiconductor nanowires. One promising method for achieving this is the sequential seeding of multiple generations of epitaxial nanowires using metal seed particles. However, it...

Axial InP nanowire tandem junction grown on a silicon substrate.

Nano letters

Heurlin M, Wickert P, Fält S, Borgström MT, Deppert K, Samuelson L, Magnusson MH.
PMID: 21456545
Nano Lett. 2011 May 11;11(5):2028-31. doi: 10.1021/nl2004219. Epub 2011 Apr 01.

Tandem InP nanowire pn-junctions have been grown on a Si substrate using metal-organic vapor phase epitaxy. In situ HCl etching allowed the different subcomponents to be stacked on top of each other in the axial extension of the nanowires...

In vivo acylation of Dictyostelium actin with palmitic acid.

The EMBO journal

Stadler J, Gerisch G, Bauer G, Deppert W.
PMID: 16453612
EMBO J. 1985 May;4(5):1153-6.

Cells of Dictyostelium discoideum were incubated with [H]palmitic acid during development, and recovery of the fatty acid label in soluble and membrane-associated proteins was investigated. One of the major labeled proteins was found exclusively in the soluble fraction. This...

Surface-enhanced Raman scattering of rhodamine 6G on nanowire arrays decorated with gold nanoparticles.

Nanotechnology

Chen J, Mårtensson T, Dick KA, Deppert K, Xu HQ, Samuelson L, Xu H.
PMID: 21828724
Nanotechnology. 2008 Jul 09;19(27):275712. doi: 10.1088/0957-4484/19/27/275712. Epub 2008 May 28.

We investigate the surface-enhanced Raman scattering (SERS) of rhodamine 6G (R6G) adsorbed on Au nanoparticles attached to InP nanowires. We find that nanowire arrays act as frameworks for effective SERS substrates with a significantly higher Raman signal sensitivity than...

Catalytic activity of nanoalloys from gold and palladium.

Physical chemistry chemical physics : PCCP

Kaiser J, Leppert L, Welz H, Polzer F, Wunder S, Wanderka N, Albrecht M, Lunkenbein T, Breu J, Kümmel S, Lu Y, Ballauff M.
PMID: 22456829
Phys Chem Chem Phys. 2012 May 14;14(18):6487-95. doi: 10.1039/c2cp23974d. Epub 2012 Mar 28.

We present a quantitative study of the catalytic activity of well-defined faceted gold-palladium nanoalloys which are immobilized on cationic spherical polyelectrolyte brushes. The spherical polyelectrolyte brush particles used as carriers for the nanoalloys consist of a solid polystyrene core...

[Advantages of digitalization and analysis of roentgenograms of bones by microcomputer.].

Acta chirurgiae orthopaedicae et traumatologiae Cechoslovaca

Tkácik J, Makai F, Keppert M, Valko B.
PMID: 20444385
Acta Chir Orthop Traumatol Cech. 1994;61(6):351-7.

The creation of an experimental group for digitalization of two-dimensional X-ray pictures of bones was the starting point for the application of selected procedures for their computer-assisted analysis. During processing of the picture first the primary digitalized picture was...

The tumor-suppressor protein p53 - relationship of structure to function (review).

Oncology reports

Sturzbecher H, Deppert W.
PMID: 21607355
Oncol Rep. 1994 Mar;1(2):301-7. doi: 10.3892/or.1.2.301.

Point mutations and/or rearrangements in the tumor suppressor gene p53 are the most common genetic alterations in human cancers. Recent observations indicate that the sum and substance of p53 protein function is the prevention of tumor formation by preservation...

The place of oxycodone/naloxone in chronic pain management.

Contemporary oncology (Poznan, Poland)

Leppert W.
PMID: 23788978

Opioid analgesics are usually effective in the management of severe chronic pain. However, symptoms of opioid-induced bowel dysfunction (OIBD) are common during opioid therapy. Opioid-induced bowel dysfunction is often unsuccessfully managed due to limited effectiveness and numerous adverse effects...
