Biotechnol Rep (Amst). 2014 Dec 05;5:112-119. doi: 10.1016/j.btre.2014.12.001. eCollection 2015 Mar.

The aim of this study was to assess the ability of selected strains of cyanobacteria and microalgae to biosynthesize silver nanoparticles (Ag-NPs) by using two procedures; (i) suspending the live and washed biomass of microalgae and cyanobacteria into the...

Radiation Therapy after Radical Prostatectomy: Implications for Clinicians.

Frontiers in oncology

Herrera FG, Berthold DR.
PMID: 27242957
Front Oncol. 2016 May 09;6:117. doi: 10.3389/fonc.2016.00117. eCollection 2016.

Depending on the pathological findings, up to 60% of prostate cancer patients who undergo radical prostatectomy (RP) will develop biochemical relapse and require further local treatment. Radiotherapy (RT) immediately after RP may potentially eradicate any residual localized microscopic disease...

Effect of an atomically thin dielectric film on the surface electron dynamics: image-potential states in the Ar/Cu(100) system.

Physical review letters

Marinica DC, Ramseyer C, Borisov AG, Teillet-Billy D, Gauyacq JP, Berthold W, Feulner P, Höfer U.
PMID: 12144494
Phys Rev Lett. 2002 Jul 22;89(4):046802. doi: 10.1103/PhysRevLett.89.046802. Epub 2002 Jul 03.

The effect of an atomically thin Ar layer on the image-potential states on Cu(100) surfaces is studied in a joint experimental-theoretical study, allowing a detailed analysis of the interaction between a surface electron and a thin insulator layer. A...

Enhanced shot noise in tunneling through a stack of coupled quantum dots.

Physical review letters

Barthold P, Hohls F, Maire N, Pierz K, Haug RJ.
PMID: 16907268
Phys Rev Lett. 2006 Jun 23;96(24):246804. doi: 10.1103/PhysRevLett.96.246804. Epub 2006 Jun 21.

We have investigated the noise properties of the tunneling current through vertically coupled self-assembled InAs quantum dots. We observe super-Poissonian shot noise at low temperatures. For increased temperature this effect is suppressed. The super-Poissonian noise is explained by capacitive...

In vitro reconstruction of a tissue-engineered endothelialized bladder from a single porcine biopsy.

Journal of pediatric urology

Magnan M, Berthod F, Champigny MF, Soucy F, Bolduc S.
PMID: 18947619
J Pediatr Urol. 2006 Aug;2(4):261-70. doi: 10.1016/j.jpurol.2005.11.019. Epub 2006 Apr 18.

OBJECTIVE: Augmentation of the urinary bladder using a tissue-engineered approach with autologous cells is a very promising technique. To prevent risks of necrosis after transplantation, the graft vascularization process could be markedly enhanced by incorporation of autologous endothelial cells...

Genetic basis of migratory behavior in European warblers.

Science (New York, N.Y.)

Berthold P, Querner U.
PMID: 17747634
Science. 1981 Apr 03;212(4490):77-9. doi: 10.1126/science.212.4490.77.

The seasonal course and magnitude of migratory restlessness recorded in four populations of the blackcap Sylvia atricapilla differ in a population-specific fashion that is related to the distance of travel. Experimentally produced hybrids of an exclusively migratory European population...

Applied Sciences: Absence of CD44-standard in human neuroblastoma correlates with histological dedifferentiation, N-myc amplification and reduced survival probability.

Cell death and differentiation

Terpe HJ, Christiansen H, Berthold F, Gonzalez M, Altmannsberger M, Schulz A, Lampert F.
PMID: 17180025
Cell Death Differ. 1994;1(2):123-8.

Expression of CD44 was examined by immunohistochemistry in 205 primary neuroblastomas together with histological grading according to the Shimada classification at the time of diagnosis. In addition, Southern blot analysis to determine N-myc gene amplification was carried out in...

Time-resolved two-photon photoemission of buried interface states in Ar/Cu(100).

Physical review letters

Rohleder M, Berthold W, Güdde J, Höfer U.
PMID: 15698130
Phys Rev Lett. 2005 Jan 14;94(1):017401. doi: 10.1103/PhysRevLett.94.017401. Epub 2005 Jan 11.

We demonstrate the existence of buried image-potential states at the interface between thick Ar films and a Cu(100) substrate. The electron dynamics of these solid-solid interface states, energetically located above the vacuum level in the band gaps of both...

Chlorophyll breakdown in spinach: on the structure of five nonfluorescent chlorophyll catabolites.

Photosynthesis research

In extracts of senescent leaves of spinach (Spinacia oleracea), five colourless compounds with UV/Vis-characteristics of nonfluorescent chlorophyll catabolites (NCCs) were detected and tentatively named So-NCCs. The most abundant polar NCC in the leaves of this vegetable, So-NCC-2, had been...

Frequency- and polarization-selective Schottky detectors in the visible and near ultraviolet.

The influence of dielectric coatings on the photoresponsivity of metal-insulator-semiconductor structures on holographic submicrometer sinusoidal grating structures is investigated. Narrow-band photodetectors are realized based on the excitation of transverse electric modes and surface plasmon polaritons in the vacuum-MgF(2)-Al or...
