The authors undertook a controlled, prospective, randomized study of 171 patients with supratentorial astrocytoma grades 3 and/or 4 (classified according to Kernohan). All patients were given chemotherapy consisting of procarbazine, vincristine, and lomustine (CCNU) (PVC). Half of the patients received whole-brain irradiation (RT) to a dose of 5800 cGy in the tumor-bearing hemisphere and 5000 cGy

Traumatic brain injury (TBI) or repeated sport-related concussions (rSRC) may lead to long-term memory impairment. Diffusion tensor imaging (DTI) is helpful to reveal global white matter damage but may underestimate focal abnormalities. We investigated the distribution of postinjury regional white matter changes after TBI and rSRC. Six patients with moderate/severe TBI, and 12 athletes with rSRC w

46 eligible patients with either anaplastic astrocytoma (AA) or glioblastoma (GBM) and clinical and computed-tomography-confirmed relapse following primary surgery and radiotherapy received oral tauromustine 130 mg/m2 every 5 weeks. A prospective design allowed for concurrent assessment of both clinical and radiological responses and drug toxicity. 41% of patients improved clinically whilst 46% im

Previous research has shown that sustainable improvements need incentives to carry them through. An assumption is that it may be easier to incorporatesustainable thinking in an organization if the organization understandswhich actions it is that are having a positive effect on sustainability andon tangible costs. This paper aims to highlight the synergy effects thatoccur in the intersection betwee

All patients in a randomized study comparing chemotherapy with chemotherapy plus radiotherapy for patients with astrocytomas grade 3 and 4, were considered for reoperation when tumour progression was established. Fifty-eight patients were reoperated and 85 were not. Different prognostic factors, such as age, sex, Karnofsky performance status and reoperation were evaluated univariately and simultan

An important part of an electrocardiogram (ECG) interpretation is the comparison between the present ECG and earlier recordings. The purpose of the present study was to evaluate a combination of two computer-based methods, synthesized vectorcardiogram (VCG) and CAVIAR, in this comparison. The methods were applied to a group of 38 normal subjects and to a group of 36 patients treated with anthracyc

In this paper we seek to reflect on the way in which 'digital cities' later re-emerge as 'smart cities' (both in terms of the approaches and also the actual cities) and what lessons can be learned about the role of ICTs in how they shape urban space. We will focus on looking at how the lack of understanding of the city as a 'place' is often a common factor in the lack of longevity in 'digital city

Floral scent is an important mediator of plant–pollinator interactions. Multiple recent studies report ample intraspecific scent variation among populations and individuals. Yet, few studies have eastimated effects of phenotypic plasticity on floral scent in response to differing environmental factors. In this study, we investigated the effects of nutrient and water availability on floral scent in

For Kristeva (1982) the abject not only caused visceral disgust but posed a threat to the established order of society. The abject is a product of particular times and places but limited attention has been given to understanding the process of transitioning away from abject status. We address this gap here through an examination of the planning profession in post-apartheid South Africa. The paper

Evolutionary ecology aims to better understand how ecologically important traits respond to environmental heterogeneity. Environments vary both naturally and as a result of human activities, and investigations that simultaneously consider how natural and human-induced environmental variation affect diverse trait types grow increasingly important as human activities drive species endangerment. Here

Pollinators experience large spatiotemporal fluctuations in resource availability when mass-flowering crops are rotated with resource-poor cereal crops. Yet, few studies have considered the effect this has on pollinator population stability, nor how this might be mitigated to maintain consistent crop pollination services. We assess the potential of boundary features (standard narrow 1 m grassy mar

Background and Aims: Alcohol use disorder (AUD) is associated with increased risk of non-fatal suicide attempt. We aimed to measure the strength and mechanistic nature of the association between AUD and increased suicide attempt and determine any causal pathways and/or shared risk factors. Design: We used Cox proportional hazards models in population-level and co-relative analyses to evaluate the

Sixty-nine patients with locally advanced breast cancer were given induction chemotherapy with doxorubicin and cyclophosphamide (day 1) followed by methotrexate and 5-Fu (day 8). Thirty-two of these patients were also given tamoxifen (days 2-6) in an attempt to induce a G1 arrest in cancer cells, and oestrogen (days 7-8) to stimulate proliferation and thus induce a synchronized wave of proliferati

Objectives: To estimate resource use and costs, including direct and indirect costs, in relation to levels of severity in individuals with Parkinson's disease (PD) in a Swedish setting. Materials and methods: Patients with idiopathic PD registered in the National Parkinson's Disease Patient Registry (PARKreg), with registrations of Hoehn and Yahr (H&Y) and “off time” in the Skåne Region, were

Drawing on interviews with selected UK planning academics and survey results from current planning practitioners, this article provides valuable and timely perspectives on how internationalisation is experienced by those within and beyond the immediate institutional context. Although internationally focused planning education helps planners tackle the manifold urban challenges in the global South,

BACKGROUND: Conventional dosages of cytostatics in mg/m2 will cause marked variations in systemic exposure, resulting in over- and under-treatment, at least with respect to side effects.PATIENTS AND METHODS: We are conducting a randomized adjuvant study for breast cancer patients younger than 60 years of age with > or = 70% risk of recurrence within five years. The first 89 consecutive patients wh

The goal of the HIBEAM/NNBAR program is to search for baryon number violation via the conversion or oscillation of neutrons into sterile neutrons and/or antineutrons at the European Spallation Source. A key experimental component of the program is the construction of an annihilation detector to directly observe the production of an antineutron following the oscillation. Design studies for the anni
