Delayed post-surgical development of dural arteriovenous fistula after cervical meningocele repair

A 34-year-old female patient presented with an intracranial subarachnoid hemorrhage and was found to have a dural arteriovenous fistula at the site of previous cervical meningocele repair. Subsequent occlusion was achieved with endovascular embolization. To our knowledge, the phenomenon of the development of a spinal dural fistula at the site of a meningocele repair has not been recorded before.

Post-(sustainable)-development?

This paper critically reviews the application of a post-development analysis to sustainable development by employing a defined target for post-development analysis – the Environmental Kuznets Curve (EKC). Data from the 2005 Environmental Sustainability Index (ESI) for 146 countries are used to generate statistically significant EKC models, and the approach is deconstructed by employing post-development theory. While an ESI derived EKC is an easy target for post-development critique, there are foundations upon which both rest, and are not easily dismissed. Neither is the typical post-development 'alternative' of encouraging 'endogenous discourse' and grassroots movements at odds with sustainable development. As a result, this paper argues that sustainable development theory already incorporates much of the critique and alternatives raised by post-developmentalists. Indeed, what is more disconcerting is that sustainable development readily encompasses such apparently divergent ideas represented by the ESI, EKC and post-developmental critique and solutions.

Water deficits promote flowering in Rhododendron via regulation of pre and post initiation development

Flowering is generally considered to be advanced by water deficits in many woody perennial species. A long-standing paradigm being that as a plant senses severe environmental conditions resources are diverted away from vegetative growth and towards reproduction before death. It is demonstrated that in Rhododendron flowering is promoted under water deficit treatments. However, the promotion of flowering is not achieved via all increase in floral initiation, but through separate developmental responses. If regulated deficit irrigation (RDI) is imposed prior to the time of initiation, fewer vegetative nodes are formed before the apical meristems switch to floral initiation, and chronologically, floral initiation occurs earlier. Both RDI and partial rootzone drying (PRD) treatments stimulate the development of more flowers Oil each inflorescence if the treatments are continued after the plant has undergone floral initiation. However, floral initiation is inhibited by soil water deficits. If the soil water deficit continues beyond the stages of floral development then anthesis call occur prematurely oil the fully formed floral buds without a need for a winter chilling treatment. It is hypothesised that inhibition of floral initiation in plants experiencing severe soil water deficits results from the inhibitory action Of ABA transportation to the apical meristem from stressed roots. It is demonstrated that ABA applications to well-watered Rhododendron inhibit floral initiation. (c) 2008 Elsevier B.V. All rights reserved.

Cardiac Na+/H+ exchanger during post-natal development in the rat: Changes in mRNA expression and sarcolemmal activity

We examined Na+–H+exchanger isoform 1 (NHE-1) mRNA expression in ventricular myocardium and its correlation with sarcolemmal NHE activity in isolated ventricular myocytes, during postnatal development in the rat. The expression of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) mRNA did not change in ventricular myocardium between 2 and 42 days after birth. Therefore, at seven time points within that age range, GAPDH expression was used to normalize NHE-1 mRNA levels, as determined by reverse transcription polymerase chain reaction analysis. There was a progressive five-fold reduction in NHE-1 mRNA expression in ventricular myocardium from 2 days to 42 days of age. As an index of NHE activity, acid efflux rates (JH) were determined in single neonatal (2–4-day-old) and adult (42-day-old) ventricular myocytes (n=16/group) loaded with the pH fluoroprobe carboxy-seminaphthorhodafluor-1. In HEPES-buffered medium, basal intracellular pH (pHi) was similar at 7.28±0.02 in neonatal and 7.31±0.02 in adult myocytes, but intrinsic buffering power was lower in the former age group. The rate at which pHirecovered from a similar acid load was significantly greater in neonatal than in adult myocytes (0.36±0.07v0.16±0.02 pH units/min at pHi=6.8). This was reflected by a significantly greaterJH(22±4v9±1 pmol/cm2/s at pHi=6.8), indicating greater sarcolemmal NHE activity in neonatal myocytes. The concomitant reductions in tissue NHE-1 mRNA expression and sarcolemmal NHE activity suggest that myocardial NHE-1 is subject to regulation at the mRNA level during postnatal development.

Resilience planning, economic change and the politics of post-recession development in London and Hong Kong

For much of the 1990s and 2000s, the emphasis of urban policy in many global cities was on managing and mitigating the social and environmental effects of rapid economic growth. The credit crunch of 2008 and the subsequent recession have undermined some of the core assumptions on which such policies were based. It is in this context that the concept of resilience planning has taken on a new significance. Drawing on contemporary research in London and Hong Kong, the paper shows how resilience and recovery planning has become a key area of political debate. It examines what is meant by conservative and radical interpretations of resilience and how conservative views have come to dominate ‘recovery’ thinking, with élite groups unwilling to accept the limits to the neo-liberal orthodoxies that helped to precipitate the economic crisis. The paper explores the implications of such thinking for the politics of urban development.

Pre- and post-natal development of the diaphragm

Animal models were used to examine properies of the diaphragm (the main respiratory muscle) before and after birth. The study revealed an insufficient blood supply to the fetus can result in structural and functional damage to the diaphragm. Damage was prevented when the mother was supplemented with creatine during pregnancy.

(Un)safe routes : maternal mortality and Ethiopia's development agenda

This study juxtaposed women's experiences of birth at home in rural Ethiopia where it is 'safe' with that in a modern health care setting where it is 'unsafe' because the distance from international maternal health policy to its implementation is vast and the 'pathway to maternal survival' can be circuitous.

Religion and post-disaster development

This chapter discusses the role religion and religious organizations can play in development following a natural disaster. The development efforts in Aceh, Indonesia, following the Indian Ocean tsunami in 2004 provide examples of how the nature of Acehnese society, its views on religion, the role of religious organizations in the region, and the activities of aid agencies at the time all contributed the the post-disaster experience in this society.The chapter also considers what the role of faith in such situations might mean for future development efforts, especially in the context of natural disaster.

The promise of a new media and development agenda

The role of the press is underpinned by a concern for public welfare, and the discourses and debates in journalism practice and theory stem from the notion that the press is one of the pillars of a democracy and an essential element of the public sphere (Rosen, 2005; Dahlgren and Sparks, 1991). The public sphere, in turn, is linked to the theory of modernisation and the development agenda of a society, where the media are expected to play an important function as watchman, policy disseminator and teacher (Schramm, 1964). This article looks at citizen journalism’s potential to provide yet another opportunity to disadvantaged communities in India to communicate with the world, via information and communication technologies. The new media also open up the possibility of these earlier disenfranchised communities becoming partners in the country’s development and democratic agenda. This is a discussion paper based on a survey of initiatives undertaken by various community groups in India to provide a voice to local communities who would otherwise remain silent. It explores the impact of these citizen journalism initiatives on local communities vis-à-vis their effectiveness as a tool for development and social change, and argues that the growth and success of these initiatives around the world, though piecemeal, should become an important part of discourse concerning the role of journalism in society.
