Specialist palliative care nursing and the philosophy of palliative care: a critical discussion

Nursing is the largest regulated health professional workforce providing palliative care across a range of clinical settings. Historically, palliative care nursing has been informed by a strong philosophy of care which is soundly articulated in palliative care policy, research and practice. Indeed, palliative care is now considered to be an integral component of nursing practice regardless of the specialty or clinical setting. However, there has been a change in the way palliative care is provided. Upstreaming and mainstreaming of palliative care and the dominance of a biomedical model with increasing medicalisation and specialisation are key factors in the evolution of contemporary palliative care and are likely to impact on nursing practice. Using a critical reflection of the authors own experiences and supported by literature and theory from seminal texts and contemporary academic, policy and clinical literature, this discussion paper will explore the influence of philosophy on nursing knowledge and theory in the context of an evolving model of palliative care

The purpose of this paper is to consider the meaning of external, internal images in the process of expression on music drama. The major results of this consideration can be summarized as follows: The external image is the "form" of reality, embodiment, that is to say, something visible and audible. On the other hand, the internal image is the simbolic form of idea, imagination, visions, enviromental factor, affect (i. e. substance of consciousness, etc.), that is to say, samething invisible. And the expression in the Music Drama is itself the mental act of representing subject subsisted in emotion and reality from expression, such as singing, acting and the theatrical line, etc..国立情報学研究所『研究紀要公開支援事業』により電子化

Increased hippocampal excitability in miR-324-null mice

MicroRNAs are non-coding RNAs that act to downregulate the expression of target genes by translational repression and degradation of messenger RNA molecules. Individual microRNAs have the ability to specifically target a wide array of gene transcripts, therefore allowing each microRNA to play key roles in multiple biological pathways. miR-324 is a microRNA predicted to target thousands of RNA transcripts and is expressed far more highly in the brain than in any other tissue, suggesting that it may play a role in one or multiple neurological pathways. Here we present data from the first global miR-324-null mice, in which increased excitability and interictal discharges were identified in vitro in the hippocampus. RNA sequencing was used to identify differentially expressed genes in miR-324-null mice which may contribute to this increased hippocampal excitability, and 3′UTR luciferase assays and western blotting revealed that two of these, Suox and Cd300lf, are novel direct targets of miR-324. Characterisation of microRNAs that produce an effect on neurological activity, such as miR-324, and identification of the pathways they regulate will allow a better understanding of the processes involved in normal neurological function and in turn may present novel pharmaceutical targets in treating neurological disease

The Corticofugal Neuron-Associated Genes ROBO1, SRGAP1, and CTIP2 Exhibit an Anterior to Posterior Gradient of Expression in Early Fetal Human Neocortex Development

Developing neocortical progenitors express transcription factors in gradients that induce programs of region-specific gene expression. Our previous work identified anteriorly upregulated expression gradients of a number of corticofugal neuron-associated gene probe sets along the anterior–posterior axis of the human neocortex (8-12 postconceptional weeks [PCW]). Here, we demonstrate by real-time polymerase chain reaction, in situ hybridization and immunohistochemistry that 3 such genes, ROBO1, SRGAP1, and CTIP2 are highly expressed anteriorly between 8-12 PCW, in comparison with other genes (FEZF2, SOX5) expressed by Layer V, VI, and subplate neurons. All 3 were prominently expressed by early postmitotic neurons in the subventricular zone, intermediate zone, and cortical plate (CP) from 8 to 10 PCW. Between 12 and 15 PCW expression patterns for ER81 and SATB2 (Layer V), TBR1 (Layer V/VI) and NURR1 (Layer VI) revealed Layer V forming. By 15 PCW, ROBO1 and SRGAP1 expression was confined to Layer V, whereas CTIP2 was expressed throughout the CP anteriorly. We observed ROBO1 and SRGAP1 immunoreactivity in medullary corticospinal axons from 11 PCW onward. Thus, we propose that the coexpression of these 3 markers in the anterior neocortex may mark the early location of the human motor cortex, including its corticospinal projection neurons, allowing further study of their early differentiation

Mechanical Flexibility Reduces the Foreign Body Response to Long-Term Implanted Microelectrodes in Rabbit Cortex.

Micromotion between the brain and implanted electrodes is a major contributor to the failure of invasive microelectrodes. Movements of the electrode tip cause recording instabilities while spike amplitudes decline over the weeks/months post-implantation due to glial cell activation caused by sustained mechanical trauma. We compared the glial response over a 26-96 week period following implantation in the rabbit cortex of microwires and a novel flexible electrode. Horizontal sections were used to obtain a depth profile of the radial distribution of microglia, astrocytes and neurofilament. We found that the flexible electrode was associated with decreased gliosis compared to the microwires over these long indwelling periods. This was in part due to a decrease in overall microgliosis and enhanced neuronal density around the flexible probe, especially at longer periods of implantation

From the Andes to the Outback : Acclimatising Alpacas in the British Empire

This article examines attempts to naturalise the alpaca in the British Empire. In the nineteenth century Britain made concerted efforts to appropriate useful plants and animals and acclimatise them within its own colonies. The alpaca was a prime target for acclimatisers on account of its silken wool, which was manufactured into a range of luxury textiles. Its export was, however, banned by law in Peru and Bolivia, so the animals had to be smuggled out of the Andean states and shipped illegally to Britain and Australia. The article studies the circuits of exchange that facilitated the transfer of alpacas from one continent to another and considers how British subjects in places as diverse as Bradford, Liverpool, Sydney and Arequipa promoted and benefited from the naturalisation scheme. It situates alpaca acclimatisation within a wider discourse of agricultural ‘improvement’, bio-piracy and imperial adventure
