A Monte Carlo model for the absorption and flux distributions of light in tissue
Brian C. Wilson,Gerhard Adam +1 more
TL;DR: A Monte Carlo computer model has been used to predict the distribution of absorbed dose in homogeneous tissues of different absorption/scattering ratios, for illumination both by external light beams and via implanted optical fibers.

Radiation exposure during midfacial imaging using 4- and 16-slice computed tomography, cone beam computed tomography systems and conventional radiography
TL;DR: Radiation doses were determined to balance risks against usefulness of the different modalities available for the imaging of the facial skeleton and multislice computed tomography showed the highest exposure values.
Exceedingly small iron oxide nanoparticles as positive MRI contrast agents
He Wei,Oliver T. Bruns,Michael G. Kaul,E. V. Hansen,Mariya Barch,Agata Wiśniowska,Ou Chen,Yue Chen,Nan Li,Satoshi Okada,Jose M. Cordero,Markus Heine,Christian T. Farrar,Daniel M. Montana,Gerhard Adam,Harald Ittrich,Alan Jasanoff,Peter Nielsen,Moungi G. Bawendi +18 more
TL;DR: Zwitterion-coated exceedingly small superparamagnetic iron oxide nanoparticles (ZES-SPIONs) as discussed by the authors are free of Gd and show a high T1 contrast power.

Size and surface effects on the MRI relaxivity of manganese ferrite nanoparticle contrast agents.
Ulrich I. Tromsdorf,Nadja C. Bigall,Michael G. Kaul,Oliver T. Bruns,Marija Nikolic,Birgit Mollwitz,Ralph A. Sperling,Rudolph Reimer,Heinz Hohenberg,Wolfgang J. Parak,Stephan Förster,Ulrike Beisiegel,Gerhard Adam,Horst Weller +13 more
TL;DR: Superparamagnetic MnFe2O4 nanocrystals of different sizes were synthesized in high-boiling ether solvent and transferred into water using three different approaches and an increase in transverse relaxivities with increasing particle size for the polymer-coated nanocrystal is observed.

Postpancreatectomy Hemorrhage: Diagnosis and Treatment: An Analysis in 1669 Consecutive Pancreatic Resections
Emre F. Yekebas,Lars Wolfram,Guellue Cataldegirmen,Christian R. Habermann,Dean Bogoevski,Alexandra M. Koenig,Jussuf T. Kaifi,Paulus G. Schurr,Michael Bubenheim,Claus Nolte-Ernsting,Gerhard Adam,Jakob R. Izbicki +11 more
TL;DR: Prognosis of PPH depends mainly on the presence of preceding pancreatic fistula, and decision making as to the indication for nonsurgical interventions should consider time of onset, presence of pancreatic Fistula, vascular pathologies, and the underlying disease.
