Single-source precursors for alloyed gold-silver nanocrystals - a molecular metallurgy approach.

Inorganic chemistry

Zopes D, Hegemann C, Schläfer J, Tyrra W, Mathur S.
PMID: 25856772
Inorg Chem. 2015 Apr 20;54(8):3781-7. doi: 10.1021/ic502924s. Epub 2015 Apr 09.

Multiple silver(I)-aurates(I) have been prepared by salt metathesis reactions that act as efficient single-source precursors to colloidal gold silver alloys with the highest possible atom economy in the chemical synthesis of nanostructures. The CF3 group present on the Au...

PMID: 20683541
Nanoscale. 2010 Oct;2(10):2091-5. doi: 10.1039/c0nr00131g. Epub 2010 Aug 04.

Nanosized (20-30 nm) colloidal gold, silver and their alloys were obtained by reductive transformation of corresponding metal salts. Dispersions of metal nanoparticles (σ < 4%) in aqueous solutions were obtained by appropriate surface functionalization which led to inorganic inks...

Kinetic Properties of Phosphoenolpyruvate Carboxylase in Peperomia camptotricha.

Plant physiology

Sipes DL, Ting IP.
PMID: 16667110
Plant Physiol. 1989 Nov;91(3):1050-5. doi: 10.1104/pp.91.3.1050.

Kinetic characteristics of phosphoenolpyruvate carboxylase (PEPC) from the epiphytic C(3) or C(4): CAM intermediate plant, Peperomia camptotricha, were investigated. Few day versus night differences in V(max),K(m(PEP))), or malate inhibition were observed, even in extracts from water-stressed plants which characteristically...

MATLAB®-based fitting method to evaluate survival fractions after multimodal treatment.

Marzec J, Marzec L, Martus P, Zips D, Müller AC.
PMID: 29928704
Clin Transl Radiat Oncol. 2018 Mar 29;10:36-41. doi: 10.1016/j.ctro.2018.03.003. eCollection 2018 Mar.

To easily analyse and visualize cell kill dynamics measured by survival fraction after single or combined treatments a MATLAB®-based application was developed. A statistical analysis with different options of visualisation of single and combined treatment effects can be performed...

Organ Preservation in Rectal Cancer: The Patients' Perspective.

Frontiers in oncology

Gani C, Gani N, Zschaeck S, Eberle F, Schaeffeler N, Hehr T, Berger B, Fischer SG, Claßen J, Zipfel S, Rödel C, Teufel M, Zips D.
PMID: 31134146
Front Oncol. 2019 May 10;9:318. doi: 10.3389/fonc.2019.00318. eCollection 2019.

Organ preservation after a clinical complete response to radiochemotherapy is currently one of the most discussed topics in the management of rectal cancer. However, the patients' perspective has only been poorly studied so far. In this multicenter study, we...

Watchful Waiting after Radiochemotherapy in Rectal Cancer: When Is It Feasible?.

Visceral medicine

Gani C, Kirschniak A, Zips D.
PMID: 31192245
Visc Med. 2019 Apr;35(2):119-123. doi: 10.1159/000499167. Epub 2019 Mar 27.

A "watch and wait" strategy in rectal cancer is increasingly considered in patients who achieve an excellent response to radiotherapy. While a growing number of studies have shown the feasibility of this strategy in selected patients, the optimal therapeutic...

A quantitative and qualitative RNA expression profiling assay for cell culture with single cell resolution.

Cytotechnology

Kraus P, Yerden R, Sipes D, Sur S, Lufkin T.
PMID: 28799096
Cytotechnology. 2018 Feb;70(1):185-192. doi: 10.1007/s10616-017-0132-1. Epub 2017 Aug 10.

Cells are often characterized by their gene expression profile. However, commonly used methods to detect mRNA require cell pooling and could therefore mask differences in gene expression within heterogeneous cell populations. q

Generation of deep ultraviolet sub-2-fs pulses.

Optics letters

Galli M, Wanie V, Lopes DP, Månsson EP, Trabattoni A, Colaizzi L, Saraswathula K, Cartella A, Frassetto F, Poletto L, Légaré F, Stagira S, Nisoli M, Martínez Vázquez R, Osellame R, Calegari F.
PMID: 30874637
Opt Lett. 2019 Mar 15;44(6):1308-1311. doi: 10.1364/OL.44.001308.

We demonstrate the generation of few-cycle deep ultraviolet pulses via frequency upconversion of 5-fs near-infrared pulses in argon using a laser-fabricated gas cell. The measured spectrum extends from 210 to 340 nm, corresponding to a transform-limited pulse duration of...

Sites of recurrent disease and prognostic factors in SCLC patients treated with radiochemotherapy.

Clinical and translational radiation oncology

Bütof R, Gumina C, Valentini C, Sommerer A, Appold S, Zips D, Löck S, Baumann M, Troost EGC.

OBJECTIVES: Concurrent radiochemotherapy (RCHT) is standard treatment in locally advanced small cell lung cancer (SCLC) patients. Due to conflicting results on elective nodal irradiation (ENI) or selective node irradiation (SNI) there is no clear evidence on optimal target volumes....
