Finding voices through writing.

Nurse educator

Gehrke P.
PMID: 7854624
Nurse Educ. 1994 Mar-Apr;19(2):28-30. doi: 10.1097/00006223-199403000-00009.

Assisting students to find their writing "voices" is another way to emphasize writing as a professional tool for nursing. The author discusses a teaching strategy that required students to write using a variety of styles. Students wrote fables, poetry,...

Overweight and obesity in hip and knee arthroplasty: Evaluation of 6078 cases.

World journal of orthopedics

Guenther D, Schmidl S, Klatte TO, Widhalm HK, Omar M, Krettek C, Gehrke T, Kendoff D, Haasper C.
PMID: 25621218
World J Orthop. 2015 Jan 18;6(1):137-44. doi: 10.5312/wjo.v6.i1.137. eCollection 2015 Jan 18.

AIM: To evaluate a possible association between the various levels of obesity and peri-operative charac-teristics of the procedure in patients who underwent endoprosthetic joint replacement in hip and knee joints.METHODS: We hypothesized that obese patients were treated for later...

Are There Carbenes in N-Heterocyclic Carbene Organocatalysis?.

Angewandte Chemie (International ed. in English)

Gehrke S, Hollóczki O.
PMID: 29072807
Angew Chem Int Ed Engl. 2017 Dec 18;56(51):16395-16398. doi: 10.1002/anie.201708305. Epub 2017 Nov 22.

Azolium cations are widely employed in organocatalysis to catalyse highly valuable synthetic processes in the presence of a base. These reactions are called "N-heterocyclic carbene catalysis", based on the assumption that they are initiated by the formation of a...

Influence of hydroxyapatite granule size, porosity, and crystallinity on tissue reaction in vivo. Part B: a comparative study with biphasic synthetic biomaterials.

Clinical oral implants research

Maté Sánchez de Val JE, Calvo-Guirado JL, Gómez-Moreno G, Gehrke S, Mazón P, De Aza PN.
PMID: 27273203
Clin Oral Implants Res. 2018 Nov;29(11):1077-1084. doi: 10.1111/clr.12880. Epub 2016 Jun 06.

OBJECTIVE: The aim of this study was to compare the influence of the physical-chemical properties of synthetic hydroxyapatite (HA) and biphasic commercial materials on the biological behavior of study materials through material characterization and SEM analysis before and after...

Fungal periprosthetic joint infection in total knee arthroplasty: a systematic review.

Orthopedic reviews

Jakobs O, Schoof B, Klatte TO, Schmidl S, Fensky F, Guenther D, Frommelt L, Gehrke T, Gebauer M.
PMID: 25874061
Orthop Rev (Pavia). 2015 Mar 09;7(1):5623. doi: 10.4081/or.2015.5623. eCollection 2015 Mar 03.

Fungal periprosthetic joint infection (PJI) is a rare but devastating complication following total knee arthroplasty (TKA). A standardized procedure regarding an accurate treatment of this serious complication of knee arthroplasty is lacking. In this systematic review, we collected data...

The Site of the Inhibition of the Shikimate Pathway by Glyphosate: II. INTERFERENCE OF GLYPHOSATE WITH CHORISMATE FORMATION IN VIVO AND IN VITRO.

Plant physiology

Amrhein N, Deus B, Gehrke P, Steinrücken HC.
PMID: 16661535
Plant Physiol. 1980 Nov;66(5):830-4. doi: 10.1104/pp.66.5.830.

In the presence of the nonselective herbicide glyphosate (N-[phosphonomethyl]glycine), buckwheat (Fagopyrum esculentum Moench) hypocotyls and cultured cells of Galium mollugo L. accumulate an organic acid, which was identified as shikimate by mass-spectroscopy of its methyl ester. After growth in...
