Objective: this study examined the generic and CF-specific QOL in CF children using a tool based on a modular clinical approach. Methods: Sample consisted of 12 CF children and 12 healthy children aged 8 to 12 years, matched by age and sex. The Quality of Life Systemic Inventory for Children (QLSI-C) assess both generic (20 items) and CF-specific (6 items) QOL. CF-specific module is empirically created from CFQ-R and discussion with medical staff. QLSI-C is a dynamic tool, using a VAS, which considers QOL (gap) like the difference between the present situation (state) and the expectations (goal). This difference is weighted by the importance (rank) that children assign for each life domains. QLSI-C is different from PedQoL, which consider QOL like an assessment of state score only. Results: Difference between CF and healthy children for the QOL score approached significance (F=3.63; p=0.07). Results by items show a significant difference for “autonomy” (F=4.30; p=0.05) and “frustration tolerance” (F=4.60; p=0.04) between the two groups. In addition, global scores in CF-specific module is correlated with global score in generic module for CF children (r=0.66 to 0.96). Assessment of QOL is the same for both generic (M=3.76) and CF-specific (M=3.76) module (p=0.53). Finally, descriptive statistics demonstrate that items which reflect the best QOL in CF children were based on social support unlike healthy children. Conclusion: QLSI-C is a clinical tool which distinguishes between children with CF and healthy children. Originality of this tool is strengthened by the consideration of individual life plan taking into account the particular situation of children with CF. [less ▲]

Humic substances (HS) are organic compounds resulting from the physical, chemical and microbiological transformations of organic residues. Present everywhere in the nature; they are taking part in basic functionalities in any ecosystems involving soils, sediments, water and landfills. They are heterogeneous and complex carbon macromolecules. Our study aims to determine the main biological properties of HS on plant growth in relation to their physicochemical properties. [less ▲]

Objectives Murine norovirus (MuNoV) belongs to the family Caliciviridae, genus Norovirus and is currently used as study model for human noroviruses, major aetiologic agents of gastroenteritis worldwide. Myxovirus (Mx) protein is an interferon-induced protein that host cell can oppose virus infection and was detected in several species including human being. In mice, two genes encoding Mx1 and 2 proteins are present but it was evidenced that these genes were inactivated by deletions in several laboratory mouse strains. Mx antiviral activity was detected on several negative stranded RNA viruses but information are still lacking for most of positive stranded RNA viruses. In this study, the susceptibility of the MuNoV to specific and interspecific Mx proteins was investigated. Methods RAW264.7 cells (murine macrophages) were first tested for constitutive expression of Mx1 proteins. Plasmids containing the murine Mx1, bovine Mx1 and human MxA genes under the CMV immediate early promotor were then used to transfect RAW264.7 cells for transient Mx expression. Negative control consisted in a plasmid expressing eGFP. Four hours after transfection, cells were infected at low MOI with the CW1 MuNoV strain. Cells and supernatants were harvested 24h post infection. RNA was extracted and viral genomic copies were measured by real time RT-PCR. Results An effect was confirmed on CW1 replication for both specific and interspecific Mx proteins. The highest effect was obtained with the bovine Mx1 protein. Conclusion In conclusion, we showed in these preliminary in vitro studies the MuNoV susceptibility to specific and interspecific Mx proteins. Bovine Mx1 protein was already demonstrated to have important antiviral activity on negative stranded RNA viruses (influenza- and paramyxoviruses) and co-evolution with the host could explain a higher susceptibility to interspecific Mx proteins. Important implications of this adaptation could be expected on zoonotic concerns associated to NoV. Moreover, even if several control studies are still be conducted to validate these preliminary results, they could drive several pertaining questions on the MuNoV model used with laboratory mice. Perspectives of this work consist to validate the susceptibility in vivo and also to test the murine Mx2 antiviral activity on MuNoV. [less ▲]

In many tropical regions of the world, humans and nonhuman primates share habitats, and their interactions are increasingly common. As a result, human presence has an important impact on the demography, behaviour, and overall ecology of the nonhuman primates’ populations. More specifically, the increasing human pressure represents a critical danger for the survival of most primate species, often leading to the local extinction of entire populations. However, some primate species show a high degree of plasticity when facing human disturbance, and even adapt their ecological behaviour to heavily modified urban areas. Our research project, in collaboration with the City of Bangkok, focuses on long-tailed macaques (Macaca fascicularis), a species distributed throughout all Southeast Asia, and showing a great ability to adapt to urban habitat. The goal of our study is to define the impact of urbanized habitat fragments on the social interaction and reproductive patterns of the macaque populations, in order to design sustainable management plans and reduce conflicts with local human populations. We present preliminary results from a 4 month study period (May to August 2007) on a large semi-provisioned troop living in the South of Bangkok suburban area. Data were collected via instantaneous scan sampling for activity budget, and focal sampling for diet, while aggressive and sexual interactions within the group were noted ad libitum. The study group, 128 animals (10 males, 6 subadults, 48 females of whom 39 with an infant, and 64 juveniles) appears to use an area highly disturbed by of human activities. In the coming year we plan to extend our observations to a second troop inhabiting an estimated area of 5 km2 of pristine mangrove with an ongoing forest regeneration project. [less ▲]

Introduction. Today, it is considered that, in children with serious illnesses such as cancer, physical activity during treatment has beneficial effects (physical and mental well-being, self-confidence and self-esteem ...)(INSERM, 2008). However, it is important to notice that physical activity has to be appropriate according to the circumstances (Herbinet, 2002). If some programs begin now to be offered in some hospitals, a lack of resources suitable for children and adolescents appears to be the norm. This study aimed to identify needs and resources for the implementation of a project like this in the department of Hematology Oncology at a hospital in the region of Liege (Wallonia, Belgium). Methods. In this perspective, we interviewed various members of the medical and paramedical staff (n = 20), young patients (n = 8) and their parents (n = 5). This triangulation process aimed to guarantee the validity of the data. The semi-structured interviews were focused on the representations of these subjects about physical activity at the hospital in young people with cancer (definition of physical activity, opportunities and habits of the young patients to exercise, benefits and risks of being active) as well as about their opinions about the characteristics of the actions to implement (type of activities, recommendations, needed resources and conditions). Respecting the principles of the qualitative research, a content analysis of the answers has been conducted. Results. Most of the subjects supported this type of project. Five categories of activities have been identified (adapted ball games, soft gymnastics, group fitness classes, relaxation activities, outdoor activities). A daily medical monitoring has been emphasized while precautionary measures have been listed, as well as the resources of the human, material, organizational and financial aspects that would be needed.

This study compares, in five species of Pomacentridae (Chromis viridis, Dascyllus flavicaudus, Chrysiptera glauca, Pomacentrus pavo, Plectroglyphidodon lacrymatus), the changes in cephalic skeletal structures between settling larvae and adults living on the reef. Variations were studied in the suspensorium, the opercle, the mandible, the premaxillary bone and the teeth. Comparisons of the feeding apparatus enabled two different types of feeding to be distinguished in adults: suction feeding and grazer sucking. Adult C. viridis and D. flavicaudus have a high suspensorium, a well-rounded mouth during jaw opening and caniniform teeth. These two species can be considered to be suction feeders. On the other hand, adult C glauca, P pavo and P lacrymatus have less developed suspensoria, opercles and ascending process of the premaxillar, and present incisiform teeth. These three species appear to be grazer suckers. However, the larvae of all five species present an unimodal way of feeding, defined as ram-suction. Differences between larvae and adults appear clearly to be related to their ecology. The increasing variation presented in feeding apparatus during the settlement phase could be linked to diversification leading to occupancy of different ecological niches. [less ▲]

In this study, the potential reduction of odor of anaerobic digestion has been evaluated in three commercial facilities located in Belgium, Luxembourg and Germany. Odor concentrations were measured by olfactometric analyses in two different situations: at normal conditions and after the stirring the odor source. Parallel to these measures, representative samples were taken for digested and untreated manure and other co-substrates present in the facilities. Volatile solids, total solids, total suspended solids, volatile suspended solids, soluble chemical oxygen demand, ammonia nitrogen, total kjeldhal nitrogen, volatile fatty acids, and pH were determined in laboratory. The performance of anaerobic digestion in terms of VFA concentration reduction achieved values of 77-96%. Odor concentration was reduced by anaerobic digestion in the two studied scenarios: at normal conditions and after the stirring the odor source. No significant effect of anaerobic digestion on chemical analyses was observed, except for an increase in the ammonia nitrogen content. Significant correlations were found between the logarithm of odor concentration and different odor compounds (VFA, acetic, butyric, isobutyric, isovaleric). Correlations between odor concentration, VFA and other parameters (VS, VSS and pH) were also obtained. These results confirm that anaerobic digestion may reduce odor annoyance potential and VFA concentrations. In addition, odor concentration seems to be related with other chemical parameters, therefore more research is needed to obtain further conclusions. [less ▲]
