Jan Dismas Zelenka’s ‘Dixit Dominus’ settings within the context of the Dresden Hofkapelle

Bohemian composer Jan Dismas Zelenka (1679–1745) composed forty-one Vespers works for performances at services of the Dresden Hofkapelle. Zelenka maintained an inventory of sacred works in his possession, which he titled ‘Inventarium rerum Musicarum Ecclesiae servientium.’ Zelenka categorized his psalm settings into two collections: thirty-three ‘Psalmi Vespertini totius anni’ and eight ‘Psalmi varii…Separatim Scripti.’ Together these psalm settings comprise four cycles of Vespers music, each of which begin with a setting of the psalm Dixit Dominus. Of the four Dixit Dominus settings (ZWV 66–69), Dixit Dominus c.1728 (ZWV 69) is now missing and Dixit Dominus 1726 (ZWV 68) was published by Carus-Verlag in 1984. The remaining two settings, Dixit Dominus c.1725 (ZWV 66) and Dixit Dominus c.1728 (ZWV 67), are presented here in critical editions. The three extant Dixit Dominus settings are analyzed from the standpoints of composition style and structure. Zelenka’s Inventarium also lists more than eighty similar Vespers works by other composers, under the heading ‘Psalmi Variorum Authorum.’ These works, which are mostly by composers of Italian and Bohemian origins, were edited and adapted by Zelenka for use at the Dresden Hofkapelle. No critical editions of these works are known to exist. Zelenka’s inventory of ‘Psalmi Variorum Authorum’ lists ten Dixit Dominus settings, of which three survive in Dresden. The three surving Dixit Dominus settings, attributed to Pitoni, Fabri, and Inge[g]nieri, are presented here with two critical editions of each: one with Zelenka’s edits included and one with Zelenka’s edits removed. In addition to an analysis of the compositions style and structure of each work, Zelenka’s approach to editing and adapting these works for use at the Dresden Hofkapelle is provided. Finally, the performance practice of the basso continuo group in Dresden is considered, with particular emphasis on Zelenka’s method of notation for this group. A select group of Zelenka’s autograph scores are used to create a set of guidelines that will assist modern editors in interpreting Zelenka’s intentions for the basso continuo group

Survival of syngeneic and allogeneic iPSC–derived neural precursors after spinal grafting in minipigs

The use of autologous (or syngeneic) cells derived from induced pluripotent stem cells (iPSCs) holds great promise for future clinical use in a wide range of diseases and injuries. It is expected that cell replacement therapies using autologous cells would forego the need for immunosuppression, otherwise required in allogeneic transplantations. However, recent studies have shown the unexpected immune rejection of undifferentiated autologous mouse iPSCs after transplantation. Whether similar immunogenic properties are maintained in iPSC-derived lineage-committed cells (such as neural precursors) is relatively unknown. We demonstrate that syngeneic porcine iPSC-derived neural precursor cell (NPC) transplantation to the spinal cord in the absence of immunosuppression is associated with long-term survival and neuronal and glial differentiation. No tumor formation was noted. Similar cell engraftment and differentiation were shown in spinally injured transiently immunosuppressed swine leukocyte antigen (SLA)–mismatched allogeneic pigs. These data demonstrate that iPSC-NPCs can be grafted into syngeneic recipients in the absence of immunosuppression and that temporary immunosuppression is sufficient to induce long-term immune tolerance after NPC engraftment into spinally injured allogeneic recipients. Collectively, our results show that iPSC-NPCs represent an alternative source of transplantable NPCs for the treatment of a variety of disorders affecting the spinal cord, including trauma, ischemia, or amyotrophic lateral sclerosis

Exoplanet Science Priorities from the Perspective of Internal and Surface Processes for Silicate and Ice Dominated Worlds

The geophysics of extrasolar planets is a scientific topic often regarded as standing largely beyond the reach of near-term observations. This reality in no way diminishes the central role of geophysical phenomena in shaping planetary outcomes, from formation, to thermal and chemical evolution, to numerous issues of surface and near-surface habitability. We emphasize that for a balanced understanding of extrasolar planets, it is important to look beyond the natural biases of current observing tools, and actively seek unique pathways to understand exoplanet interiors as best as possible during the long interim prior to a time when internal components are more directly accessible. Such pathways include but are not limited to: (a) enhanced theoretical and numerical modeling, (b) laboratory research on critical material properties, (c) measurement of geophysical properties by indirect inference from imprints left on atmospheric and orbital properties, and (d) the purpose-driven use of Solar System object exploration expressly for its value in comparative planetology toward exoplanet-analogs. Breaking down barriers that envision local Solar System exploration, including the study of Earth's own deep interior, as separate from and in financial competition with extrasolar planet research, may greatly improve the rate of needed scientific progress for exoplanet geophysics. As the number of known rocky and icy exoplanets grows in the years ahead, we expect demand for expertise in 'exogeoscience' will expand at a commensurately intense pace. We highlight key topics, including: how water oceans below ice shells may dominate the total habitability of our galaxy by volume, how free-floating nomad planets may often attain habitable subsurface oceans supported by radionuclide decay, and how deep interiors may critically interact with atmospheric mass loss via dynamo-driven magnetic fields

Barriers to effective discharge planning: a qualitative study investigating the perspectives of frontline healthcare professionals

<p>Abstract</p> <p>Background</p> <p>Studies have shown that effective discharge planning is one of the key factors related to the quality of inpatient care and unnecessary hospital readmission. The perception and understanding of hospital discharge by health professionals is important in developing effective discharge planning. The aims of this present study were to explore the perceived quality of current hospital discharge from the perspective of health service providers and to identify barriers to effective discharge planning in Hong Kong.</p> <p>Methods</p> <p>Focus groups interviews were conducted with different healthcare professionals who were currently responsible for coordinating the discharge planning process in the public hospitals. The discussion covered three main areas: current practice on hospital discharge, barriers to effective hospital discharge, and suggested structures and process for an effective discharge planning system.</p> <p>Results</p> <p>Participants highlighted that there was no standardized hospital-wide discharge planning and policy-driven approach in public health sector in Hong Kong. Potential barriers included lack of standardized policy-driven discharge planning program, and lack of communication and coordination among different health service providers and patients in both acute and sub-acute care provisions which were identified as mainly systemic issues. Improving the quality of hospital discharge was suggested, including a multidisciplinary approach with clearly identified roles among healthcare professionals. Enhancement of health professionals' communication skills and knowledge of patient psychosocial needs were also suggested.</p> <p>Conclusions</p> <p>A systematic approach to develop the structure and key processes of the discharge planning system is critical in ensuring the quality of care and maximizing organization effectiveness. In this study, important views on barriers experienced in hospital discharge were provided. Suggestions for building a comprehensive, system-wide, and policy-driven discharge planning process with clearly identified staff roles were raised. Communication and coordination across various healthcare parties and provisions were also suggested to be a key focus.</p
