PURPOSE: Retrospective studies have shown similar survival among patients with acute myeloid leukemia (AML) and myelodysplasia (MDS) after nonmyeloablative compared with myeloablative conditioning. Refined risk stratification is required to design prospective trials. PATIENTS AND METHODS: We stratified outcomes among patients with AML (n = 391) or MDS (n = 186) who received either nonmyeloablative (n = 125) or myeloablative (n = 452) allogeneic hematopoietic cell transplantation (HCT) based on comorbidities, as assessed by a HCT-specific comorbidity index (HCT-CI), as well as disease status. Patients receiving nonmyeloablative conditioning were older, more frequently pretreated, more often received unrelated grafts, and more often had HCT-CI scores of 3 compared with patients who received myeloablative conditioning. RESULTS: Patients with HCT-CI scores of 0 to 2 and either low or high disease risks had probabilities of overall survival at 2 years of 70% and 57% after nonmyeloablative conditioning compared with 78% and 50% after myeloablative conditioning, respectively. Patients with HCT-CI scores of 3 and either low or high disease risks had probabilities of overall survival of 41% and 29% with nonmyeloablative conditioning compared with 45% and 24% with myeloablative regimens, respectively. After adjusting for pretransplantation differences, stratified outcomes were not significantly different among patients receiving nonmyeloablative compared with myeloablative conditioning, with the exception of lessened nonrelapse mortality (hazard ratio, 0.50; P = .05) in the highest risk group. CONCLUSION: Patients with low comorbidity scores could be candidates for prospective randomized trials comparing nonmyeloablative and myeloablative conditioning regardless of disease status. Additional data are required for patients with low-risk diseases and high comorbidity scores. Novel antitumor agents combined with nonmyeloablative HCT should be explored among patients with high comorbidity scores and advanced disease. [less ▲]

The hoverfly Episyrphus balteatus De Geer (Diptera: Syrphidae) is an abundant and efficient aphid-specific predator. Several aphidophagous parasitoids and predators are known to respond positively to aphid-infested plants. Semiochemicals from the latter association usually mediate predator/parasitoid foraging behavior toward sites appropriate for offspring fitness. In this study, we investigated the effect of aphid host plant and aphid species on foraging and oviposition behavior of E. balteatus. Behavioral observations were conducted using the Noldus Observer v. 5.0, which allows observed insect behavior to be subdivided into different stages. Additionally, the influence of aphid species and aphid host plant on offspring fitness was tested in a second set of experiments. Acyrthosiphon pisum Harris and Megoura viciae Buckton were equally attractive for E. balteatus whereas Aphis fabae Scopoli (all Homoptera: Aphididae) were less attractive. These results were correlated with (i) the number of eggs laid, which was significantly higher for the two first aphid species, and (ii) the fitness of hoverfly larvae, pupae, and adults. Two solanaceous plant species, Solanum nigrum L. and Solanum tuberosum L. (Solanaceae), which were infested with Myzus persicae Sulzer (Homoptera: Aphididae), were also compared using the same approach. Discrimination between these two M. persicae host plants was observed, with S. tuberosum being preferred as an oviposition site by the predatory hoverfly. Larval and adult fitness was correlated with the behavioral observations. Our results demonstrated the importance of the prey-host plant association on the choice of the oviposition site by an aphid predator, which is here shown to be related to offspring fitness.

OBJECTIVE: To identify brain regions generating tics in patients with Tourette syndrome using sleep as a baseline. METHODS: We used [15O]H2O PET to study nine patients with Tourette syndrome and nine matched control subjects. For patients, conditions included tic release states and sleep stage 2; and for control subjects, rest states and sleep stage 2. RESULTS: Our study showed robust activation of cerebellum, insula, thalamus, and putamen during tic release. CONCLUSION: The network of structures involved in tics includes the activated regions and motor cortex. The prominent involvement of cerebellum and insula suggest their involvement in tic initiation and execution. [less ▲]

In Moldavia, three sequences serve as the basis for the chronological context for Gravettian (and Epigravettian) occupations. Two technological phases have been identified, showing independent development, homogenous in both technological and typological attributes. The Gravettian is characterized by large retouched blades, followed by shouldered points (29,500-23,000 BP), succeeded by the Early Epigravettian (13,500-11,000 BP). [less ▲]

The aims of this study were to characterise a model of feline allergic airway inflammation and to test through a longitudinal investigation whether five repeated allergen exposures would lead to signs of airway remodelling that would be detectable in vivo. Eight healthy control cats and eight cats sensitised with Ascaris suum allergens were investigated. Barometric whole body plethysmography (BWBP) was used for the assessment of respiratory variables and airway responsiveness (AR). Bronchoalveolar lavage fluid (BALF) was sampled for cytology and determination of F-2-isoprostane concentration and matrix metalloproteinase type 9 (MMP-9) activity. Thoracic radiography and bronchoscopy scores were also established. Cats were investigated prior to sensitisation and after inhalation of placebo or allergen challenge 1. BWBP measurements revealed a significant increase of enhanced pause (Penh), an index of bronchoconstriction, and AR in sensitised cats in response to allergen challenge 1. A significant increase in BALF neutrophil and eosinophil %, F-2-isoprostane concentration and MMP-9 activity, and increased radiography and bronchoscopy scores were recorded. After a recovery period of 6 weeks, all variables except BALF MMP-9 returned to baseline values. Four further allergen challenges induced similar changes to those seen in challenge I and no signs of persistent changes suggestive of bronchial remodelling were detectable. The model provides an in vivo approach to functional, inflammatory and morphological changes occurring in response to single and repeated allergen exposure. [less ▲]

Stricturing subocclusive small bowel Crohn's disease (CD) is often an indication for surgery. We embarked on an open label pilot study to assess the safety and efficacy of infliximab in patients with stricturing subocclusive CD. Patients and methods : A cohort of patients with a documented and symptomatic small bowel stricture caused by CD was studied. Patients had to be refractory to corticosteroids and/or immunosuppressives, and not in need for immediate surgery. The patients were treated by a single infusion of infliximab 5 mg/kg and followed up at w1, w2, w4 and w8. Results : After the 6(th) patients, the study was prematurely discontinued because the predefined safety thresholds of more than 2 surgeries within the first 5 patients was reached. Only two patients completed the 8 weeks study, with a positive response to infliximab and improvement of inflammation confirmed by the CRP and CT scan. Two patients had to be operated early and the last two patients first did well but worsened after one month and were operated 35 and 42 days after infliximab, respectively. No surgical complications occurred in the 4 operated patients. In conclusion, a subset of patients with subocclusive small bowel stricturing CD may benefit from infliximab. [less ▲]

Numerical modelling of the lateral-torsional buckling of steel beams at elevated temperature has shown that the beam design curve from EN 1993-1-2 is over-conservative in the case of non-uniform bending. Based on the newly proposed methodology for cold design from the EN 1993-1-1, an improved proposal for the lateral-torsional buckling of unrestrained steel beams subjected to fire is presented in this paper that addresses the issue of the influence of the loading type, the steel grade, the pattern of the residual stresses (hot-rolled or welded sections) and the ratio h/b, between the depth h and the width b of the cross-section on the resistance of the beam, achieving better agreement with the numerical behaviour while maintaining safety. The proposal is found to be safe and accurate through an extensive comparison with the results of FEM numerical simulations of more than 5000 beams. A statistical study of the results is performed, showing the accuracy of the improved proposal presented in this paper. (C) 2007 Elsevier Ltd. All rights reserved. [less ▲]

In 2000, the Walloon Region (Belgium) has initiated a research program at the Standing Conference on Territorial Development (CPDT) in order to address the European Landscape Convention requirements. The research concentrated at first on the identification and the typology of Walloon macrolandscapes at a regional scale. Then the research focussed on the landscapes characterisation at a scale of 1/20 000 and their patrimonial qualification. The paper traces the research progress (definition of the concepts of landscape and patrimonial landscape, the adopted procedure) and presents the elaborated method to appreciate the landscapes scientific values, called the method of the “witness landscape”. It also presents the difficulties met during its application on the field. The method is iterative and combines the observation on the field, the review of both historic and present cartographies, the interpretation of aerial photographs and the mobilisation of the available bibliography. Reading, analysing, nderstanding and documenting the landscape in order to highlight the meaningful landscapes’ configurations and components, such was one of the research team contributions to the landscape management.

The territorial sensitivities method was proposed as a tool to collect senses of places and meanings of landscape features. It was presented as an alternative of the traditional participation process to take into account the inhabitants’ meanings in physical planning projects. The method is based on the comparison of an “objective” inventory of localisable changes and those collected in the speech of the inhabitants. Analysing which changes are mentioned but also which ones are absent contributes to grasp the places appropriation. After a short presentation of the method, the paper asks about the acceptability of this one in the context of the territorial intelligence. Is it suitable to join non participative empathic methods in the set of tools of the territorial intelligence? [less ▲]
