Long-term bone marrow culture profiles in patients with myelodysplastic syndromes are not explicable by defective apoptosis

It has been suggested that increased intramedullary apoptosis may explain the paradox between peripheral blood cytopenias and the hyper- or normo-cellular bone marrow observed in the myelodysplastic syndromes (MDS). We wished to see if culture performance could be related to the presence of apoptotic cells in a group of patients with MDS (12 patients) and other patients with peripheral blood cytopenias (six patients) which caused diagnostic difficulty. There was no correlation between LTBMC or adherent cell growth and the presence of apoptotic cells in the original marrow sample. A variable degree of apoptosis was observed in both groups of patients. LTBMC profiles correlated well with diagnosis but were unrelated to the extent of intramedullary apoptosis. This suggests that apoptosis is a much more ubiquitous process in disease than previously thought. (C) 1998 Elsevier Science Ltd. All rights reserved.

A practical miniature long-term bone marrow culture system for investigating early myelodysplasia

A method was devised to grow haemopoietic cells in long-term bone marrow culture (LTBMC) which requires only 1 x 10(6) cells/culture. Such miniature cultures were used to study growth patterns of marrow from patients with myelodysplastic syndromes (MDS). Consistent differences in LTBMC cellularity and cellular composition were noted between MDS and normal marrow. These differences were accentuated by rGM-CSF. The criteria which distinguished between and MDS marrows were: cell count at weeks 1 and 4, % neutrophils and % blasts. In 10 patients with unexplained macrocytosis or pancytopenia miniature LTBMC results clearly segregated into either 'normal' or 'MDS' growth patterns. Miniature LTBMC with rGM-CSF may therefore be a useful diagnostic test for early MDS.

Sexing up the city in the international beauty contest: the performative nature of spatial planning and the fictive spectacle of place branding

This paper responds to recent calls for more academic research and critical discussion on the relationship between spatial planning and city branding. Through the lens of Liverpool, the article analyses how key planning projects have delivered major transformations in the city's built environment and cultural landscape. More specifically, in concentrating on the performative nature of spatial planning it reveals the physical, symbolic and discursive re-imaging of Liverpool into a 'world class city'. Another aspect of the paper presents important socioeconomic datasets and offers a critical reading of the re-branding in showing how it presents an inaccurate representation of Liverpool. The evidence provided indicates that a more accurate label for Liverpool is a polarised and divided city, thereby questioning the fictive spectacle of city branding. Finally, the paper ends with some critical commentary on the role of spatial planning as an accessory to the sophistry of city branding.

A new landscape of arts-based buildings and comparative cultural policies on the island of Ireland: the curse of Jocasta's necklace

Much current cultural policy research focuses on activity traditionally viewed as arts practice: visual arts, music, literature and dance. Architecture’s role in the discussion of cultural policy is, however, less certain and thus less frequently interrogated. The study presented here both addresses this dearth of in-depth research while also contributing to the interdisciplinary discussion of cultural policy in wider terms. In seeking to better understand how architectural culture is regulated and administered in a specific case study, it unpacks how the complicated relationships of nominal and explicit policies on both sides of the Irish/Northern Irish border contributed to the significant expansion of arts-based buildings 1995-2008. It contrasts political and cultural motivations behind these projects during a period of significant economic growth, investment and inward immigration. Data has been gathered from both official published policies as well as interviews with elite actors in the decision-making field and architects who produced the buildings of interest in both countries. With the sizeable number of arts-based buildings now completed in both Republic of Ireland and Northern Ireland, one must wonder if this necklace of buildings is, like Jocasta’s, a thing of both beauty and redolent with a potential future curse. It is the goal of this project to contribute to the larger applied and critical discussion of these issues and to engage with future policy design, administration and, certainly, evaluation.
