Normalized mass mapping of Orbitrap data to define complex, polyglycerol-based raw material compositions.

Kendrick Mass Mapping of complex sample compositions, via data derived by Fourier transform ion cyclotron resonance mass spectrometry (FTICRMS) at 1,000,000 resolution, is becoming more common. The Orbitrap mass spectrometer (Fourier Transform Axially Harmonic Orbital Trapping) also uses FT methods and indirect detection, though operating at a maximum resolution of 100,000. We define the more general case of Normalized Mass Mapping to any repeating oligomer unit (e.

Long sick leave after orthopaedic inpatient rehabilitation: treatment failure or relapse?

We investigated whether short-term versus long-term sick leave after orthopaedic inpatient rehabilitation can be predicted by initial assessment information, the clinical status at discharge, or whether the follow-up interval is crucial for later sick leave. We examined 214 patients from an orthopaedic rehabilitation hospital at admission, discharge and 1-year follow-up. Outcome measures included disability, depression, self-efficacy, health status and attitudes towards work.

Separation and analysis of dimethylaniline isomers by supercritical fluid chromatography--electrospray ionization tandem mass spectrometry.

The assessment of human exposure to specific isomers of dimethylanilines (DMA's) is of interest for the evaluation of potential exposure-health outcome relationships. Improved analytical methods will help in identifying the environmental sources of such exposures. The separation of all six DMA isomers by supercritical fluid chromatography (SFC), without derivatization, is reported within.

Evaluation of a behavioral-medical inpatient rehabilitation treatment including booster sessions: a randomized controlled study.

Objectives: The aim of this randomized controlled study was to investigate whether additional psychologic interventions in the context of multidisciplinary inpatient pain treatment increases treatment efficacy compared with normal orthopedic rehabilitation. In addition, we aimed to demonstrate the additional benefit of a subsequent maintenance program in further stabilizing treatment successes.

Methods: We randomly assigned 363 chronic back pain patients to 1 of 3 treatment conditions: traditional orthopedic rehabilitation, multidisciplinary (behavioral-medical) rehabilitation alone, and multidisciplinary rehabilitation with subsequent booster sessions.

[The assignment of orthopaedic rehabilitants to the traditional or the behaviour-medical rehabilitation approach--is it clinically relevant?].

Rehabilitants with chronic orthopaedic diseases are assigned to either the traditional or the behaviour-medical rehabilitation approach by consultant physicians of the rehabilitation department within the Deutsche Rentenversicherung Bund (German pension insurance agency). The clinical relevance of this assignment was evaluated at the Rehazentrum Bad Pyrmont-Klinik Weser within a randomised controlled trial. In a sample of 363 rehabilitants the agreement of consultant physicians with the ratings of physicians and psychologists in the clinic was analyzed.

[Patients with versus without psychological disorders in orthopedic rehabilitation].

Background: In this study it was examined whether orthopedic rehabilitants with versus without a comorbid mental disorder profit from inpatient orthopedic rehabilitation to the same degree. It was also investigated whether there were differential treatment effects between the traditional and behavioral-medical rehabilitation approaches.

Method: Questionnaires which assess pain-specific and associated variables were issued to a total of 361 patients on admission and discharge from rehabilitation.

Identification of a giant cell fibroma.

Fibrous hyperplastic connective tissue lesions are common in the oral cavity and may be similar both clinically and histologically. A giant cell fibroma, a type of fibrous hyperplasia, was discovered during a preventive patient visit in the dental hygiene clinic at a Midwestern university. The patient, a 19-year-old female, presented with a dome-shaped lesion of normal mucosal color on the attached gingiva apical to tooth number 11.

Effect of ionic additives on the elution of sodium aryl sulfonates in supercritical fluid chromatography.

Addition of a small amount of polar solvent (i.e., modifier) to CO2 in packed column supercritical fluid chromatography (SFC) has shown major improvements in both polar analyte solubility and interaction of the polar analyte with the stationary phase.

Investigating magnetically aligned phospholipid bilayers with EPR spectroscopy at 94 GHz.

In this paper, we report our initial results on studying magnetically aligned phospholipid bilayers (bicelles) at high magnetic fields (approximately 3.4 T) with electron paramagnetic resonance (EPR) spectroscopy at 95 GHz (W-band). In order to characterize this system for W-band EPR studies, we have utilized the nitroxide spin probe 3beta-doxyl-5alpha-cholestane to demonstrate the effects of macroscopic bilayer alignment.

Consultation--liaison psychiatry activities in a renal transplant unit.

We describe the consultation--liaison psychiatry activites in the renal transplant unit at Hannover Medical School. The activities with regard to patients' care include: the group session, with particular regard to dealing with the patients' denial; the indirect and direct psychotherapeutic interventions, the latter concerning psychotherapeutic consultation and counselling ('supportive psychotherapy'); and dealing with live donors and potential renal transplant patients. The second consultation--liaison psychiatry activity includes the teaching procedures: firstly, Balint-group-work with the nurses, secondly, the nurses' presence in the group sessions, and finally, Balint-group-work with students working as auxiliary therapists.
