Abstract
Fecal microbiota transplantation (FMT) has been used empirically for decades in equine medicine to treat intestinal dysbiosis but evidence-based information is scarce. This in vitro study aimed at assessing the effect of a commonly used pre-FMT processing method on the bacterial composition and viability of the fecal filtrate. Three samples of fresh equine manure (T0) were processed identically: the initial manure was mixed with 1 L of lukewarm water and chopped using an immersion blender to obtain a mixture (T1), which was left uncovered during 30 min (T2) and percolated through a sieve to obtain a fecal filtrate (T3). Samples were taken throughout the procedure (Tn) and immediately stored at 4 °C until processing. The 16S rDNA amplicon profiling associated with propidium monoazide treatment was performed on each sample to select live bacteria. Analyses of α and β diversity and main bacterial populations and quantitative (qPCR) analysis were performed and statistically compared (significance p < 0.05) between time points (T0-T3). No significant differences in ecological indices or mean estimated total living bacteria were found in the final fecal filtrate (T3) in regard to the original manure (T0); however, relative abundances of some minor genera (Fibrobacter, WCHB1-41_ge and Akkermansia) were significantly different in the final filtrate. In conclusion, the results support the viability of the major bacterial populations in equine feces when using the described pre-FMT protocol.

Abstract
Abstract
Purpose
The present prospective study evaluates the association between new bone formation rate in the iliac onlay graft and sex steroid hormone serum levels.
Methods
A total of 15 partially or completely edentulous postmenopausal females and 9 males with less than 5 mm height of the remaining alveolar bone underwent iliac onlay grafting followed by dental implant placement using a two-stage approach. Sex hormone binding globulin and 17β-estradiol serum levels were investigated by electrochemiluminescence immunoassay, while total testosterone level was analyzed using radioimmunoassay. At the time of implant placement, 12 weeks after grafting, bone biopsies were obtained and analyzed histomorphometrically. Statistical analysis was performed using linear mixed models.
Results
Grafting procedure was successfully performed in all patients. The mean new bone formation rate was 32.5% (116 samples). In men the mean new bone formation rate (38.1%) was significantly higher (p < 0.01) than in women (27.6%). Independent of gender 17β-estradiol and testosterone were positively associated to overall new bone formation rate, albeit a significant influence was only seen for 17β-estradiol in men (p = 0.020). Sex hormone binding globulin had no influence on new bone formation rate (p = 0.897). There was no significant association between new bone formation rate and age (p = 0.353) or new bone formation rate and body mass index (p = 0.248).
Conclusion
Positive association of 17ß-estradiol as well as testosterone with new bone formation rate after iliac onlay grafting indicates a role of sex steroid hormones in alveolar bone regeneration, although the observed influence was only significant for 17ß-estradiol in men.

Abstract
INTRODUCTION The treatment of cancer patients in Germany is characterized by sectoral separation of the in- and outpatient care accompanied by 2 separate reimbursement systems. By introducing the Guideline of Outpatient Medical Specialist Care in accordance with §116b SGB V (ASV) in 2014, the German legislation empowers office-based physicians and hospitals to jointly provide medical care in the ambulatory setting. METHODS A 1-year period each before and after the introduction of ASV was compared by means of data from the Center for Integrated Oncology Cologne at the University Hospital of Cologne. Only adults with a reliable diagnosis of gastrointestinal tumor (GIT) were considered. RESULTS Overall, 1,872 cases were considered in the analysis showing significant (p < 0.001) higher median values of revenues across ICD-subgroups for ASV (EUR 427.46) compared to Ambulatory Treatments in Hospitals (EUR 234.21). The exemplary analysis of revenues in neoplasms of the pancreas shows EUR 173.69 on average which are only invoiceable through ASV: flat rate incl. surcharges (EUR 117.79; 68%), structure lump sum (EUR 29.49; 17%), positron-emission tomography (PET)/CT (EUR 13.53; 18%), and ASV consultation hour (EUR 12.89; 7%). DISCUSSION/CONCLUSION ASV leads to significant higher revenues across different ICD-subgroups for patients suffering from severe GIT. The collaboration of hospital and office-based physicians ensures patient-centered care with accumulated expertise and avoidance of double examinations. Thus, the inclusion of additional services in the Uniform Value Scale (invoiceable for ASV) is legitimated and enables cost-covering care for the involved parties.

Abstract
Novel nanofabrication methods and the discovery of an efficient manipulation of local magnetization based on spin polarized currents has generated a tremendous interest in the field of spintronics. The search for materials allowing for fast domain wall dynamics requires fundamental research into the effects involved (Oersted fields, adiabatic and non-adiabatic spin torque, Joule heating) and possibilities for a quantitative comparison. Theoretical descriptions reveal a material and geometry dependence of the non-adiabaticity factor β, which governs the domain wall velocity. Here, we present two independent approaches for determining β: (i) measuring the dependence of the dwell times for which a domain wall stays in a metastable pinning state on the injected current and (ii) the current-field equivalence approach. The comparison of the deduced β values highlights the problems of using one-dimensional models to describe two-dimensional dynamics and allows us to ascertain the reliability, robustness and limits of the approaches used.
