Population dynamics, diet and spatial use of the edible dormouse Glis glis were studied in a peripheral population in Belgium, on the western limit of its distribution area. The main results showed that the proportion of occupied nest boxes varied between 2 and 44 %. The dormice occupied nest boxes approximately between June and October. The densities of adults varied between 0.6 and 2.3/ha. Reproduction was observed in 2006 and 2007 but not in 2005. The results of the diet study revealed a basically herbivorous diet. Home range (MCP) of males varied from 0.68 to 1.23 ha and that of females from 0.37 to 0.71 ha. Marked individuals moved on average 252 m/night (range = 60-497 m/night). In general, these results are in accordance with those observed in other countries. Only few differences appeared and they concern mainly a smaller number of occupied nest boxes, a smaller density and a higher proportion of birds in the diet of the species. [less ▲]

Collagens are major constituents of connective tissues in the animal kingdom. During aging and inflammatory-related diseases, the collagen network undergoes oxidation that leads to structural and biochemical alterations within the collagen molecule. Collagen oxidation appears to be a key determinant of aging and a critical physiopathologic mechanism of numerous diseases. Further, the detection of oxidized-collagen peptides seems to be a promising approach for the diagnosis and the prognosis of inflammatory diseases. This chapter reviews the structural and biochemical changes to collagen induced by reactive oxygen and nitrogen species and discusses recent data on the use of collagen-derived biomarkers for measuring oxidative damage.

The language profile of patients suffering from Alzheimer's disease (AD) is characterized not only by lexicosemantic impairments but also by phonological deficits, as shown by an increasing number of neuropsychological studies. This study explored the functional neural correlates underlying phonological and lexicosemantic processing in AD. Using H(215)O PET functional brain imaging, a group of mild to moderate AD patients and a group of age-matched controls were asked to repeat four types of verbal stimuli: words, wordlike nonwords (WL+), non-wordlike nonwords (WL-) and simple vowels. The comparison between the different conditions allowed us to determine brain activation preferentially associated with lexicosemantic or phonological levels of language representations. When repeating words, AD patients showed decreased activity in the left temporo-parietal and inferior frontal regions relative to controls, consistent with distorted lexicosemantic representations. Brain activity was abnormally increased in the right superior temporal area during word repetition, a region more commonly associated with perceptual-phonological processing. During repetition of WL+ and WL- nonwords, AD patients showed decreased activity in the middle part of the superior temporal gyrus, presumably associated with sublexical phonological information; at the same time, AD patients showed larger activation than controls in the inferior temporal gyrus, typically associated with lexicosemantic levels of representation. Overall, the results suggest that AD patients use altered pathways to process phonological and lexicosemantic information, possibly related to a progressive loss of specialization of phonological and lexicosemantic neural networks.

From a case-study based on an analysis model, which takes into account four levels of explanation (personal, interpersonal, group and organizational), and includes the study of the interactions between these different levels, this report puts forward six observations: (1) the importance of performing the analysis on several levels, (2) the existence within harassment situations of two types of process (victimizing and conflictual), (3) the fact that these processes can co- exist at different levels of analysis, (4) the existence of interactions between processes, (5) the variability of a situation across time, and (6) the necessity of distinguishing two categories of influence involved in contextual processes. From these conclusions, the authors develop a new analysis model, which is process- based, integrative and dynamic. [less ▲]

Plant population differentiation may play a role in decreasing the ability to predict whether, where, and when an introduced species will invade. However, few studies have addressed the level of genetic change an alien species may undergo during range expansion, e.g. in response to climatic variation with altitude. In the present study, we tested the hypothesis that invasive populations of Senecio inaequidens (Asteraceae) differentiated during migration from two independent introduction sites into divergent altitudinal and climatic zones. We carried out two years of common garden experiments with eight populations from a Belgian altitudinal transect and ten populations from similar French transect. Climatic analysis revealed that the Belgian transect followed a temperature and precipitation gradient. A temperature and summer drought gradient characterized the French study site. We evaluated differentiation and clinal variation in the following characters: days to germination, days to flowering, height at maturity, final plant height and aboveground biomass. Results showed that S. inaequidens populations differentiated in growth traits during invasion. First year of experiment, regressing population growth trait means against source population altitude indicated the presence of clinal variation along both transects. Second year, similar results were found along the French transect, i.e. a reduction in height at maturity, plant height and aboveground biomass with increasing altitude. Including seed mass as a covariate did not change the outcome of the analysis. The possible evolutionary causes for the differentiation observed are discussed. [less ▲]

Pseudomonas aeruginosa is a ubiquitous gram-negative bacterium, which is also able to cause severe opportunistic infections in humans. The colonization of the host is importantly affected by the production of the high-affinity iron (III) scavenging peptidic siderophore pyoverdine. The species P. aeruginosa can be divided into three subgroups ('siderovars'), each characterized by the production of a specific pyoverdine and receptor (FpvA). We used a multiplex PCR to determine the FpvA siderovar on 345 P. aeruginosa strains from environmental or clinical origin. We found about the same proportion of each type in clinical strains, while FpvA type I was slightly over-represented (49%) in environmental strains. Our multiplex PCR also detected the presence or absence of an additional receptor for type I pyoverdine (FpvB). The fpvB gene was in fact present in the vast majority of P. aeruginosa strains (93%), regardless of their siderovar or their origin. Finally, molecular analyses of fpvA and fpvB genes highlighted a complex evolutionary history, probably linked to the central role of iron acquisition in the ecology and virulence of P. aeruginosa.

BACKGROUND: Internationally, nursing is not well represented in hospital financing systems. In Belgium a nursing weight system exists to adjust budget allocation for differences in nurse staffing requirements, but there is a need for revision. Arguments include the availability of a nursing minimum dataset and the adverse consequences of the current historically based nursing weight system. OBJECTIVES: The development and validation of nursing resource weights for the revised Belgium nursing minimum dataset (NMDS). DESIGN: Two independent cross sectional Delphi-surveys. SETTING AND PARTICIPANTS: A convenience sample of 222 head nurses from 69 Belgian hospitals participated in the cross sectional survey methods. To assess validity 112 patient case records from 61 nursing wards of 35 Belgian general hospitals representing general, surgical, pediatric, geriatric and intensive care were selected. METHODS: Nursing resource weights were constructed based on Delphi survey results by NMDSII intervention. The patient case Delphi survey results were used as the primary source for validation. A series of additional validation measures were calculated, based on the different patient classification systems. Finally, three validated nursing resource weighting systems were compared to the constructed NMDSII weighting system: the use of 'Closon', 'Ghent' and WIN weights. RESULTS: A coherent set of nursing resource weights was developed. The comparison of nurse resource weights, based on the survey per NMDS intervention versus the survey on patient cases, yielded high correlations: r=0.74 to r=0.97 (p<0.01) between three case rating questions, as an indication of reliability in terms of internal consistency, and r=0.90 (p<0.01) between summed intervention weights and patient case weights, as an indication of criterion validity in terms of concurrent validity. Other concurrent validity measures based on summed intervention weights versus patient classification dependency weights showed a correlation ranging from r=0.14 to r=0.74. The correlation of summed intervention weights with the Closon, Ghent and WIN weights ranged from r=0.93 to r=0.96 (p<0.01), as a third indication of concurrent validity. CONCLUSIONS: A system of valid nursing resource weights has been developed. The system should be further validated within an international context. [less ▲]
