Revealing heterogeneous nucleation of primary Si and eutectic Si by AlP in hypereutectic Al-Si alloys.

Scientific reports

Li J, Hage FS, Liu X, Ramasse Q, Schumacher P.
PMID: 27120994
Sci Rep. 2016 Apr 28;6:25244. doi: 10.1038/srep25244.

The heterogeneous nucleation of primary Si and eutectic Si can be attributed to the presence of AlP. Although P, in the form of AlP particles, is usually observed in the centre of primary Si, there is still a lack...

Ion mass and energy selective hyperthermal ion-beam assisted deposition setup.

The Review of scientific instruments

Gerlach JW, Schumacher P, Mensing M, Rauschenbach S, Cermak I, Rauschenbach B.
PMID: 28667984
Rev Sci Instrum. 2017 Jun;88(6):063306. doi: 10.1063/1.4985547.

For the synthesis of high-quality thin films, ion-beam assisted deposition (IBAD) is a frequently used technique providing precise control over several substantial film properties. IBAD typically relies on the use of a broad-beam ion source. Such ion sources suffer...

COMT Val158Met Polymorphism Modulates Cognitive Effects of Dietary Intervention.

Frontiers in aging neuroscience

Witte AV, Jansen S, Schirmacher A, Young P, Flöel A.
PMID: 21119769
Front Aging Neurosci. 2010 Nov 05;2:146. doi: 10.3389/fnagi.2010.00146. eCollection 2010.

A common single nucleotide polymorphism (SNP) in the gene encoding catechol-O-methyltransferase (COMT), Val158Met, is thought to influence cognitive performance due to differences in prefrontal dopaminergic neurotransmission. Previous studies lend support for the hypothesis that the "at risk" genotype comprising...

In-situ activated macrophages are involved in host-resistance to lymphoma metastasis by production of nitric-oxide.

International journal of oncology

Umansky V, Rocha M, Kruger A, Vonhoegen P, Schirrmacher V.
PMID: 21552802
Int J Oncol. 1995 Jul;7(1):33-40.

We studied nitric oxide (NO) production, adenosine deaminase (ADA) and 5'-nucleotidase (5-N) activity as a function of macrophage activation in the model of spontaneous metastasis of ESbL T lymphoma cells transduced with the lacZ gene. Liver and spleen macrophages...

Spectral reflectance and responsivity of Ge- and InGaAs-photodiodes in the near-infrared: measurement and model.

Applied optics

López M, Hofer H, Stock KD, Bermúdez JC, Schirmacher A, Schneck F, Kück S.
PMID: 17932548
Appl Opt. 2007 Oct 10;46(29):7337-44. doi: 10.1364/ao.46.007337.

The spectral reflectance and responsivity of Ge- and InGaAs-photodiodes at (nearly) normal and oblique incidence (45 degrees) were investigated. The derived data allow a calculation of the photodiodes responsivities for any incident angle. The measurements were carried out with...

Changes in liver glycogen and lipid metabolism during transient graft-versus-host (GvH) and graft-versus-leukemia (GvL) reactivity.

International journal of oncology

Lee K, Hacker H, Umansky V, Schirrmacher V, Rocha M.
PMID: 21541563
Int J Oncol. 1996 Oct;9(4):635-43. doi: 10.3892/ijo.9.4.635.

We investigated the influence of transient graft-versus-leukemia (GvL) and graft-versus-host reactivity (GvH) following allogeneic immune cell transfer on the glycogen and lipid metabolism in the liver of affected mice to better understand the underlying mechanism of these phenomena. As...

Elevated expression of c-kit in small venous malformations of blue rubber bleb nevus syndrome.

Rare tumors

Mogler C, Beck C, Kulozik A, Penzel R, Schirmacher P, Breuhahn K.
PMID: 21139838
Rare Tumors. 2010 Jun 30;2(2):e36. doi: 10.4081/rt.2010.e36.

The blue rubber bleb nevus syndrome (BRBNS, syn. bean syndrome) is a rare disease characterized by multiple cutaneous and gastrointestinal venous malformations associated with severe bleeding. However, the underlying molecular mechanisms are unknown and no targeted therapeutic approach exists...

Activated endothelial cells induce apoptosis in lymphoma cells.

International journal of oncology

Umansky V, Bucur M, Schirrmacher V, Rocha M.
PMID: 21533398
Int J Oncol. 1997 Mar;10(3):465-71. doi: 10.3892/ijo.10.3.465.

We have previously shown that the arrest or regression of mouse liver metastases formed by lacZ-transduced ESbL T lymphoma cells (ESbL-lacZ) is associated with the stimulation of nitric oxide (NO) production by liver endothelial cells in sis. Here we...

Adoptive transfer via immune T-lymphocytes of effective anti-tumor immunity against a malignant rat glioma in the brain.

International journal of oncology

Naujocks G, Serwe M, Bayer T, Schirrmacher V.
PMID: 21528207
Int J Oncol. 1997 Aug;11(2):249-54. doi: 10.3892/ijo.11.2.249.

The aim of the present study was to develop an animal model to test the therapeutic potential of purified CD4 and CD8 T-lymphocytes against the intracerebrally implanted rat glioma cell line TZ363. Peripheral immunization of donor rats was performed...

Effective introduction of T cell costimulatory molecules into virus modified tumor cell vaccines by modification with bispecific antibodies.

International journal of oncology

Haas C, Schirrmacher V.
PMID: 21528289
Int J Oncol. 1997 Nov;11(5):951-7. doi: 10.3892/ijo.11.5.951.

This report describes the generation of bispecific antibodies which bind with one arm to virus modified tumor cell vaccines and introduce with the other arm anti-murine CD28 T cell costimulatory molecules. This is an effective alternative to somatic gene...
