Reciproc vs. hand instrumentation in dental practice: a study in routine care.

PeerJ

Bartols A, Reutter CA, Robra BP, Walther W.
PMID: 27375972
PeerJ. 2016 Jun 28;4:e2182. doi: 10.7717/peerj.2182. eCollection 2016.

Background. Little is known about the clinical impact of new root canal preparation systems in general dental practice under routine care conditions. Therefore, we compared hand instrumentation (H) with Reciproc (R) (VDW, Munich, Germany) preparation. The outcomes were endodontic...

De Novo Sequencing and Resurrection of a Human Astrovirus-Neutralizing Antibody.

Bogdanoff WA, Morgenstern D, Bern M, Ueberheide BM, Sanchez-Fauquier A, DuBois RM.
PMID: 27213181
ACS Infect Dis. 2016 May 13;2(5):313-321. doi: 10.1021/acsinfecdis.6b00026. Epub 2016 Mar 14.

Monoclonal antibody (mAb) therapeutics targeting cancer, autoimmune diseases, inflammatory diseases, and infectious diseases are growing exponentially. Although numerous panels of mAbs targeting infectious disease agents have been developed, their progression into clinically useful mAbs is often hindered by the...

Evaluation of methods for pore generation and their influence on physio-chemical properties of a protein based hydrogel.

Biotechnology reports (Amsterdam, Netherlands)

Bodenberger N, Kubiczek D, Abrosimova I, Scharm A, Kipper F, Walther P, Rosenau F.
PMID: 28352549
Biotechnol Rep (Amst). 2016 Sep 09;12:6-12. doi: 10.1016/j.btre.2016.09.001. eCollection 2016 Dec.

Different methods to create and manipulate pore sizes in hydrogel fabrication are available, but systematic studies are normally conducted with hydrogels made of synthetic chemical compounds as backbones. In this study, a hydrogel made of natural and abundant protein...

New pathways for improved quantification of energy-dispersive X-ray spectra of semiconductors with multiple X-ray lines from thin foils investigated in transmission electron microscopy.

Journal of microscopy

Parri MC, Qiu Y, Walther T.
PMID: 26769195
J Microsc. 2015 Dec;260(3):427-41. doi: 10.1111/jmi.12345. Epub 2015 Nov 02.

Theoretical approaches to quantify the chemical composition of bulk and thin-layer specimens using energy-dispersive X-ray spectroscopy in a transmission electron microscope are compared to experiments investigating (In)GaAs and Si(Ge) semiconductors. Absorption correctors can be improved by varying the take-off...

Four-Wave Mixing in Landau-Quantized Graphene.

Nano letters

König-Otto JC, Wang Y, Belyanin A, Berger C, de Heer WA, Orlita M, Pashkin A, Schneider H, Helm M, Winnerl S.
PMID: 28234493
Nano Lett. 2017 Apr 12;17(4):2184-2188. doi: 10.1021/acs.nanolett.6b04665. Epub 2017 Feb 28.

For Landau-quantized graphene, featuring an energy spectrum consisting of nonequidistant Landau levels, theory predicts a giant resonantly enhanced optical nonlinearity. We verify the nonlinearity in a time-integrated degenerate four-wave mixing (FWM) experiment in the mid-infrared spectral range, involving the...

Highly sensitive ammonia sensors for environmental monitoring are presented. The sensing materials are based on fluorescent BF

Teaching in daily clinical practice: a necessary evil or an opportunity? Doctors as teachers.

European journal of trauma and emergency surgery : official publication of the European Trauma Society

Ruesseler M, Walcher F.
PMID: 26814957
Eur J Trauma Emerg Surg. 2011 Apr;37(2):203-5. doi: 10.1007/s00068-011-0078-5. Epub 2011 Feb 19.

Teaching is an important part of our medical role as physicians. Though all doctors are usually well prepared for their clinical roles, few are trained to teach. It can be demonstrated that improved teaching performance leads to better learning...

Focused Echocardiography in Life Support: The Subcostal Window : What the Surgeon Should Know for Critical Care Applications.

European journal of trauma and emergency surgery : official publication of the European Trauma Society

Breitkreutz R, Walcher F, Ilper H, Seeger FH, Price S, Via G, Steiger H.
PMID: 26815049
Eur J Trauma Emerg Surg. 2009 Aug;35(4):347. doi: 10.1007/s00068-009-9093-1. Epub 2009 Jul 15.

CONTEXT: Focused echocardiography evaluation in life support (FEEL) for emergency and critical caremedicine is an innovative approach to introducing limited-in-scope echocardiography in a timely fashion into periresuscitation care. FEEL is an advanced life support-conformed concept and a simple procedure...

Recodable surfaces based on switchable hydrogen bonds.

Chemical communications (Cambridge, England)

Wedler-Jasinski N, Delbosc N, Virolleaud MA, Montarnal D, Welle A, Barner L, Walther A, Bernard J, Barner-Kowollik C.
PMID: 27339101
Chem Commun (Camb). 2016 Jul 05;52(56):8753-6. doi: 10.1039/c6cc03612k.

We introduce recodable surfaces solely based on reversible artificial hydrogen bonding interactions. We show that a symmetrical oligoamide (SOA) attached to poly(methyl methacrylate) (PMMA) can be repeatedly immobilized and cleaved off spatially defined surface domains photochemically functionalized with asymmetric...
