Films of cerium-doped LaMnO3, which has been intensively discussed as an electron-doped counterpart to hole-doped mixed-valence lanthanum manganites during the past decade, were analyzed by x-ray photoemission spectroscopy with respect to their manganese valence under photoexcitation. The comparative analysis...

Spectral and spatial shaping of laser-driven proton beams using a pulsed high-field magnet beamline.

Brack FE, Kroll F, Gaus L, Bernert C, Beyreuther E, Cowan TE, Karsch L, Kraft S, Kunz-Schughart LA, Lessmann E, Metzkes-Ng J, Obst-Huebl L, Pawelke J, Rehwald M, Schlenvoigt HP, Schramm U, Sobiella M, Szabó ER, Ziegler T, Zeil K.
PMID: 32499539
Sci Rep. 2020 Jun 04;10(1):9118. doi: 10.1038/s41598-020-65775-7.

Intense laser-driven proton pulses, inherently broadband and highly divergent, pose a challenge to established beamline concepts on the path to application-adapted irradiation field formation, particularly for 3D. Here we experimentally show the successful implementation of a highly efficient (50%...

Fibroblasts in normal and pathological terminal differentiation, aging, apoptosis and transformation.

Archives of gerontology and geriatrics

Bayreuther K, Francz PI, Rodemann HP.
PMID: 18647676
Arch Gerontol Geriatr. 1992;15:47-74. doi: 10.1016/s0167-4943(05)80006-8.

Fibroblast populations have been considered as homogeneous non-differentiating cell populations until nowadays. Such undefined fibroblast populations have been predominant cell systems for qualitative and/or quantitative studies in general cell biology, biochemistry and virology, and more specialized issues like differentiation,...

Late Side Effects in Normal Mouse Brain Tissue After Proton Irradiation.

Frontiers in oncology

Suckert T, Beyreuther E, Müller J, Azadegan B, Meinhardt M, Raschke F, Bodenstein E, von Neubeck C, Lühr A, Krause M, Dietrich A.
PMID: 33520710
Front Oncol. 2021 Jan 11;10:598360. doi: 10.3389/fonc.2020.598360. eCollection 2020.

Radiation-induced late side effects such as cognitive decline and normal tissue complications can severely affect quality of life and outcome in long-term survivors of brain tumors. Proton therapy offers a favorable depth-dose deposition with the potential to spare tumor-surrounding...

Amyloid Abeta levels in Alzheimer's disease - A diagnostic tool and the key to understanding the natural history of Abeta?.

Journal of Alzheimer's disease : JAD

McLean CA, Beyreuther K, Masters CL.
PMID: 12214051
J Alzheimers Dis. 2001 Jun;3(3):305-312. doi: 10.3233/jad-2001-3305.

The biogenesis and degradation/clearance of Abeta amyloid lies at the centre of the pathogenesis of Alzheimer's disease. Quantification of the various metabolic pools of Abeta in the brains and in the periphery may aid in diagnosis, prognosis and the...

Applying Tissue Slice Culture in Cancer Research-Insights from Preclinical Proton Radiotherapy.

Suckert T, Rassamegevanon T, Müller J, Dietrich A, Graja A, Reiche M, Löck S, Krause M, Beyreuther E, von Neubeck C.
PMID: 32560230
Cancers (Basel). 2020 Jun 16;12(6). doi: 10.3390/cancers12061589.

A challenge in cancer research is the definition of reproducible, reliable, and practical models, which reflect the effects of complex treatment modalities and the heterogeneous response of patients. Proton beam radiotherapy (PBRT), relative to conventional photon-based radiotherapy, offers the...

Demonstration of the spin solar cell and spin photodiode effect.

Nat Commun. 2013;4:2068. doi: 10.1038/ncomms3068.

Spin injection and extraction are at the core of semiconductor spintronics. Electrical injection is one method of choice for the creation of a sizeable spin polarization in a semiconductor, requiring especially tailored tunnel or Schottky barriers. Alternatively, optical orientation...

Cowpea mosaic virus VPg: sequencing of radiochemically modified protein allows mapping of the gene on B RNA.

EMBO J. 1984 Jul;3(7):1629-34.

A partial amino acid sequence of cowpea mosaic virus (CPMV) VPg radiochemically modified by chloramine-T and Bolton-Hunter reagent has been determined. VPg covalently bound to viral RNA chains (VPg-RNA) was iodinated with chloramine-T and Bolton-Hunter reagent to label tyrosine...

Pancreatic ductal adenocarcinoma (PDAC) is a highly therapy-resistant tumor entity of unmet needs. Over the last decades, radiotherapy has been considered as an additional treatment modality to surgery and chemotherapy. Owing to radiosensitive abdominal organs, high-precision proton beam radiotherapy...
