This article focuses on the studies and discourses of mostly British scholars of the early colonial period belonging to two schools of thought. It shows how the studies of both schools – European orientalism and utilitarianism – were intricately connected to the political development of the emerging British paramountcy over the South Asian sub-continent, as both were looking for means of establishing and/or strengthening colonial rule. Nevertheless, the debate was not just a continuation of discussions in Europe. Whereas the ideas of the European Enlightenment had some influence, the transformation of the Mughal Empire and especially the idea of a decline of Muslim rule offered ample opportunities for understanding the early history of India either as some sort of “Golden Age,” as the orientalists and their indigenous supporters did, or as something static and degenerate, as the utilitarians did, and from which the population of sub-continent had to be saved by colonial rule and colonial values. Fearing the spread of the ideas of the French Revolution, the first group of British scholars sought to persuade the native elites of South Asia to take the lessons of their past for the future development of their homeland. Just as the classicists back in Europe, these scholars were convinced that large-scale explanations of the past could also teach political and moral lessons for the present although it was important to deal with the distant past in an empirical manner. The utilitarians on the other hand believed that India had to be saved from its own depravity through the English language and Western values, which amounted to nothing less than the modern transformation of the true Classical Age.

Virus-like particles (VLPs) are non-infectious self-assembling nanoparticles, useful in medicine and nanotechnology. Their repetitive molecularly-defined architecture is attractive for engineering multivalency, notably for vaccination. However, decorating VLPs with target-antigens by genetic fusion or chemical modification is time-consuming and often leads to capsid misassembly or antigen misfolding, hindering generation of protective immunity. Here we establish a platform for irreversibly decorating VLPs simply by mixing with protein antigen. SpyCatcher is a genetically-encoded protein designed to spontaneously form a covalent bond to its peptide-partner SpyTag. We expressed in E. coli VLPs from the bacteriophage AP205 genetically fused to SpyCatcher. We demonstrated quantitative covalent coupling to SpyCatcher-VLPs after mixing with SpyTag-linked to malaria antigens, including CIDR and Pfs25. In addition, we showed coupling to the VLPs for peptides relevant to cancer from epidermal growth factor receptor and telomerase. Injecting SpyCatcher-VLPs decorated with a malarial antigen efficiently induced antibody responses after only a single immunization. This simple, efficient and modular decoration of nanoparticles should accelerate vaccine development, as well as other applications of nanoparticle devices.

BACKGROUND Newly diagnosed WHO grade II-III or any WHO grade recurrent meningioma exhibit an aggressive behavior and thus are considered as high- or intermediate risk tumors. Given the unsatisfactory rates of disease control and survival after primary or adjuvant radiation therapy, optimization of treatment strategies is needed. We investigated the potential of dose-painting intensity-modulated proton beam-therapy (IMPT) for intermediate- and high-risk meningioma. MATERIAL AND METHODS Imaging data from five patients undergoing proton beam-therapy were used. The dose-painting target was defined using [68]Ga-[1,4,7,10-tetraazacyclododecane tetraacetic acid]- d-Phe(1),Tyr(3)-octreotate ([68]Ga-DOTATATE)-positron emission tomography (PET) in target delineation. IMPT and photon intensity-modulated radiation therapy (IMRT) treatment plans were generated for each patient using an in-house developed treatment planning system (TPS) supporting spot-scanning technology and a commercial TPS, respectively. Doses of 66 Gy (2.2 Gy/fraction) and 54 Gy (1.8 Gy/fraction) were prescribed to the PET-based planning target volume (PTVPET) and the union of PET- and anatomical imaging-based PTV, respectively, in 30 fractions, using simultaneous integrated boost. RESULTS Dose coverage of the PTVsPET was equally good or slightly better in IMPT plans: dose inhomogeneity was 10 ± 3% in the IMPT plans vs. 13 ± 1% in the IMRT plans (p = 0.33). The brain Dmean and brainstem D50 were small in the IMPT plans: 26.5 ± 1.5 Gy(RBE) and 0.002 ± 0.0 Gy(RBE), respectively, vs. 29.5 ± 1.5 Gy (p = 0.001) and 7.5 ± 11.1 Gy (p = 0.02) for the IMRT plans, respectively. The doses delivered to the optic structures were also decreased with IMPT. CONCLUSIONS Dose-painting IMPT is technically feasible using currently available planning tools and resulted in dose conformity of the dose-painted target comparable to IMRT with a significant reduction of radiation dose delivered to the brain, brainstem and optic apparatus. Dose escalation with IMPT may improve tumor control and decrease radiation-induced toxicity.

Im Jahr 1866 verfasste der damals in Breslau lehrende römisch-katholische Kirchenhistoriker Joseph Hubert Reinkens eine der ersten historisch-kritischen Studien in deutscher Sprache über Martin von Tours, in der er sich u.a. mit Martins bischöflichem Leitungsdienst befasste. Nach dem Ersten Vatikanischen Konzil (1870) wurde Reinkens 1873 der erste Bischof für die Alt-Katholiken im Deutschen Reich. Der Beitrag beschreibt den Einfluss, den Reinkens' Martin-Rezeption auf sein theologisches und praktisches Verständnis des Bischofsamts hatte.
