Das Repertorium Academicum Germanicum (RAG). Ein digitales Forschungsvorhaben zur Geschichte der Gelehrten des alten Reiches (1250-1550)

This article aims at presenting an already existing research project. The Repertorium Academicum Germanicum (RAG) is supposed to be a "Who’s who" of the graduated and noble scholars of the late medieval Empire. It is designed to record biographical and social data of graduated theologians, jurists, physicians and Masters of Art as well as data of nobles from universities between 1250 and 1550. Furthermore, the project focuses on their examinations, networks, fields of activity in ecclesiastical and secular offices as well as their achievements and legacies (books, treatises, tombs etc). Right now, over 49.000 prosopographic entries are stored in the RAG database, partly available online (www.rag-online.org) and combined with digital maps (infographics), which already provide a basis for research in academic mobility determined by the top scholars of the time. In a next step, it should be possible to draw conclusions not only about personnel and knowledge transfer from university to society, its effects on political systems, daily life, the emergence of new occupational groups and professions, but also about cultural exchange within Europe.

[Polymyalgia rheumatica: What is the current status?]

The diagnosis of polymyalgia rheumatica (PMR) is based on the typical clinical symptoms and elevated inflammatory markers in blood; however, both are unspecific and the differential diagnosis of the disease still represents a challenge for clinicians. The new consensus classification criteria of the European League Against Rheumatism (EULAR) and the American College of Rheumatology (ACR) established in 2012 have a high sensitivity (92.6 %) and specificity (91.2 %) and therefore contribute to improved diagnostics. Glucocorticoids are still the standard treatment with methotrexate and as an alternative and possibly anti-interleukin (anti-IL) 6 therapy in the future.

Influence of Chilling Stress on the Intercellular Distribution of Assimilatory Sulfate Reduction and Thiols in Zea mays

Abstract: The effect of chilling on the intercellular distribution of mRNAs for enzymes of assimilatory sulfate reduction, the activity of adenosine 5′-phosphosulfate reductase (APR), and the level of glutathione was analysed in leaves and roots of maize (Zea mays L). At 25 °C the mRNAs for APR, ATP sulfurylase, and sulfite reductase accumulated in bundle-sheath only, whereas the mRNA for O-acetylserine sulfhydrylase was also detected in mesophyll cells. Glutathione was predominantly detected in mesophyll cells; however, oxidized glutathione was equally distributed between the two cell types. Chilling at 12 °C induced oxidative stress which resulted in increased concentrations of oxidized glutathione in both cell types and a prominent increase of APR mRNA and activity in bundle-sheath cells. After chilling, mRNAs for APR and sulfite reductase, as well as low APR activity, were detected in mesophyll cells. In roots, APR mRNA and activity were at higher levels in root tips than in the mature root and were greatly increased after chilling. These results demonstrate that chilling stress affected the levels and the intercellular distribution of mRNAs for enzymes of sulfate assimilation.

Intraoperative image-guided navigation system: development and applicability in 65 patients undergoing liver surgery

Background Image-guided systems have recently been introduced for their application in liver surgery.We aimed to identify and propose suitable indications for image-guided navigation systems in the domain of open oncologic liver surgery and,more specifically, in the setting of liver resection with and without microwave ablation. Method Retrospective analysis was conducted in patients undergoing liver resection with and without microwave ablation using an intraoperative image-guided stereotactic system during three stages of technological development (accuracy: 8.4 ± 4.4 mm in phase I and 8.4 ± 6.5 mm in phase II versus 4.5 ± 3.6 mm in phase III). It was evaluated, in which indications image-guided surgery was used according to the different stages of technical development. Results Between 2009 and 2013, 65 patients underwent image-guided surgical treatment, resection alone (n=38), ablation alone (n =11), or a combination thereof (n =16). With increasing accuracy of the system, image guidance was progressively used for atypical resections and combined microwave ablation and resection instead of formal liver resection (p<0.0001). Conclusion Clinical application of image guidance is feasible, while its efficacy is subject to accuracy. The concept of image guidance has been shown to be increasingly efficient for selected indications in liver surgery. While accuracy of available technology is increasing pertaining to technological advancements, more and more previously untreatable scenarios such as multiple small, bilobar lesions and so-called vanishing lesions come within reach.
