This paper deals mainly with pneumatic measurements on a radial turbine nozzle cascade. The fill radial cascade guarantees the exit flow field periodicity downstream of it. A special traversing mechanism with a five - hole conical probe moving along a circular path behind the cascade was used for flow field investigation in this type of cascade with very low aspect ratio. The analyses of results of 2D and 3D pneumatic measurements including loss coefficient values are presented.

A catalogue of possible landslide initial failure mechanisms, taking into account the geological setting and the geometry of the slope, the joint structure, the habitus of the rock blocks, as well as the mechanical behaviour of the rocks and of the rock mass (deformation and strength parameters), is presented. Its aim is to give geologists as well as engineers the opportunity to compare phenomena in the field and phenomena belonging to particular mechanisms and to find the mechanism occurring. The presented catalogue of initial landslide mechanisms only comprises the mechanisms having a clearly defined mechanical model that can be divided into empirical relations and into mechanical models, as well as an overview of run out models, which can be divided into empirical relations and into mechanical models.

Since its discovery in the 1920’s the relaxin peptide hormone family has not only grown in number to now seven members （relaxin-1, relaxin-2, relaxin-3, insulin-like peptide （INSL） 3, INSL4, INSL5 and INSL6）, but ever more effects, suchs as vasodilatory, angiogenic, anti-apoptopic, anti-fibriotic and anti-inflammatory, have been linked to them. While relaxin-2 has mainly been investigated in the context of cardiac protection, most comprehensively in the RELAX-AHF and RELAX AHF2 studies, a small number of studies have furthermore assessed the potential neuroprotective effects of especially relaxin-2 and other members of the relaxin family. In this short review we summarise and discuss recent efforts to utilize relaxin hormones for neuroprotection and point out potential future fields of research and translational applications. While many questions still need to be answered, the promising results of the available studies definitely warrant future well-designed studies on neuroprotection by relaxin peptides.

Background: Since January 1st of 2005, the situation of bariatric surgery is being analyzed in Germany. The data is registered prospectively in cooperation with the Institute of Quality Assurance in Surgery at the Otto-von-Guericke University Magdeburg. Methods: The data is registered through an online database which includes all information for primary and revision bariatric procedures as well as yearly follow-up. Participation in the quality assurance study is optional. All certificated centers have to participate at the survey. Results: From January 2006 to December 2009, 1478 sleeve gastrectomies (SG) were performed at 45 hospitals. The number of procedures has increased from 126 in 2007 to 933 in 2009. The main complication is leakage of the staple-line. Initial leakage rate was 7% in 2007. Leakage rate dropped down to 2.3% in 2008 and 2.5% in 2009. Mean age of patients was 43.1 years and mean BMI was 52.83 kg/m2. Age and BMI were significantly higher in patients with SG than in all other patients undergoing bariatric surgery. Conclusion: SG is a common and hype bariatric procedure in Germany, but postoperative complication rate is high. Data on the long-term effect of SG on weight loss and amelioration of comorbidities need to be evaluated. More detailed analyzes are necessary to establish the position of SG in the bariatric surgery. Further studies should also include examinations on long-term complications and redo-procedure after SG.

In 1988, rudolf Pichlmayr pioneered split liver transplantation(SLT), enabling the transplantation of one donor liver into two recipients-one pediatric and one adult patient. In the same year, Henri Bismuth and colleagues performed the first full right/full left split procedure with two adult recipients. Both splitting techniques were rapidly adopted within the transplant community. However, a SLT is technically demanding, may cause increased perioperative complications, and may potentially transform an excellent deceased donor organ into two marginal quality grafts. Thus, crucial evaluation of donor organs suitable for splitting and careful screening of potential SLT recipients is warranted. Furthermore, the logistic background of the splitting procedure as well as the organ allocation policy must be adapted to further increase the number and the safety of SLT. Under defined circumstances, in selected patients and at experienced transplant centers, SLT outcomes can be similar to those obtained in full organ LT. Thus, SLT is an important tool to reduce the donor organ shortage and waitlist mortality, especially for pediatric patients and small adults. The present review gives an overview of technical aspects, current developments, and clinical outcomes of SLT.

目的靶向前列腺特异性膜抗原（PSMA）的放射性显像剂在许多正常结构、解剖变异和非前列腺癌组织中有摄取。该研究探讨PSMA靶向显像剂18F-DCFPyL在外周神经节PET显像的摄取频次和程度。方法回顾性分析98例接受18F-DCFPyL PET/CT显像的患者,包括76例前列腺癌（PCa）男性患者和22名肾细胞癌（RCC）患者（男13例、女9例）。评估颈、星状、腹腔、腰、骶神经节的摄取。记录所有放射性摄取高于背景的神经节的摄取值,包括最大标准摄取值(SUVmax)和用瘦体质量校准的SULmax。计算SUVmax和SULmax除以升主动脉平均摄取(Aortamean)和右臀肌肉平均摄取(Gluteusmean),得到神经节/背景比值。结果 98例患者中有95例（96.9%）在至少1个外周神经节中有摄取。在PCa病例中,最常见的放射性聚集部位是腰交感神经节（55/76,72.4%）,其次是颈神经节（51/76,67.1%）。大多数患者是双侧摄取[腰椎44/55（80%）和颈椎30/51（58.8%）]。此外,星状神经节、腹腔神经节、骶神经节有明显放射性摄取者比例分别为65.8%（50/76）、59.2%（45/76）、6.6%（5/76）。RCC患者也有类似的发现,最常见的放射摄取部位是腰神经节（90.9%,20/22）和颈神经节（86.4%,19/22）。这2个部位的PSMA配体平均摄取量在PCa和RCC中均无差异。结论随着靶向PSMA显像剂的广泛应用,必须了解其在肿瘤不直接相关的组织结构中的摄取方式。该研究首次系统评价18F-DCFPyL在神经节中的摄取,结果显示其在腰椎、颈椎、星状神经节、腹腔神经节和骶神经节中的摄取频率呈下降趋势。然而,导致PSMA靶向放射性显像剂在外周神经节中摄取出现差异的生物学原因目前尚不清楚,需进一步研究。
