Possible space experiments for observing the geometric, spectroscopic, and photometric behavior of comets are described. These experiments are proposed beacause an interpretation of cometary data may yield essential data on the formation and evolution of the solar system and the nature of interplanetary space. The various ways of obtaining significant planetary data are examined. These include the use of: (1) far ultraviolet observations by orbiting astronomical observatories; (2) artificial gaseous comets formed by high-altitude release of gases such as NH[SUB]3[/SUB]; (3) orbiting artificial cometary nuclei such as blocks of CO[SUB]2[/SUB] or NH[SUB]3[/SUB] ice, perhaps with an addition of meteoric material; and (4) fly-by p probes of a comet such as Encke's periodic comet. The significance of the data that would be obtained by each of these methods is predicted. [less ▲]

Agar contact microbiological sampling techniques, based on a transfer of the microorganisms present on a surface to a culture medium, are widely used to assess and control surface cleanliness and to evaluate microbial contamination levels. The effectiveness of these techniques depends on many environmental parameters that influence the strength of attachment of the bacteria to the surface. In the present study, stainless steel and high density polyethylene surfaces were inoculated with known concentrations of Staphylococcus epidermidis. Following an experimental design, the surfaces were sampled with different types of replicate organism direct agar contact plates and Petrifilm; results indicated that recovery rates were influenced by the presence of egg white albumin or Tween 80 in the inoculum solutions or by the introduction of surfactants into the contact agar of the microbiological sampling techniques. The techniques yielded significantly different results, depending on sampling conditions, underlining the need for a standardization of laboratory experiments to allow relevant comparisons of such techniques.

Neutrophils (PMNs) are involved in host defense against infections through the production of reactive oxygen species (ROS) to kill pathologic agents. But, an excessive ROS production, called “oxidative stress” is associated with tissue damages and development of chronic or acute inflammatory diseases. PMNs are prime therapeutic targets to control inflammatory events associated to ROS production. Nowadays, there is a growing interest for the use of polyphenolic molecules to modulate the inflammatory response. The aim of this work was to study the antioxidant effect of NDS27 (1), a new highly water-soluble form of the polyphenolic molecule curcumin, on in vitro stimulated equine PMNs. NDS27 (10-6 to 10-4 M) was pre-incubated with cells and eliminated before their activation. The ability of NDS27 to enter into the cells was checked by HPLC from the cellular extracts. The intracellular ROS production by phorbol myristate acetate (PMA) stimulated PMNs was measured by fluorescence using 2’,7’-dichlorofluorescin diacetate. Lucigenin dependent chemiluminescence was used to measure extracellular ROS production. Additionally, the effect of NDS27 was tested on the activity of myeloperoxidase (MPO), a hemic enzyme contributing to the oxidant response of neutrophils. The activity of the released MPO by cytochalazine B (CB) and N-formyl-methionyl-leucyl-phenylalanine (fMLP) stimulated PMNs was measured by SIEFED (“Specific Immunologic Extraction Followed by Enzymatic Detection”) (2). The HPLC results showed that NDS27 enters into PMNs and interacts with their membrane. NDS27 significantly and dose-dependently inhibited the ROS production in neutrophils without affecting their viability. Likewise, the activity of MPO released by PMNs was lowered by NDS27. Overall, our findings demonstrate that the membrane of neutrophils is permeable to NDS27 or interacts with the drug, suggesting that its inhibitory effect on ROS production is mainly associated to an intracellular effect probably by acting on the enzymes implied in respiratory burst like NADPH oxidase and MPO. The modulatory effect of NDS27 towards the oxidant activity of cells involved in immune and inflammatory response open therapeutic perspectives to control equine or human pathologies with excessive inflammatory reactions. 1.

The incidences of clinical and biological markers of atopy were investigated in 16 children with IgA nephropathy (IgAN) (group A) and in 22 with Henoch-Schonlein purpura nephritis (HSPN) (group B). The incidence of increased plasma IgE levels according to age-matched normal values was significantly higher in group B (17/22, 77%) than in group A (7/16, 44%) (P < 0.05). Although not significant, the incidences of positive RAST tests and of a history of typical atopic symptoms were also higher in group B [10/22 (45%) and 11/22 (50%), respectively] than in group A [4/16 (25%) and 5/16 (31%), respectively]. Moreover, IgE deposits were demonstrated by a peroxidase/anti-peroxidase method on cutaneous Langerhans and mast cells in 4 of 6 patients with HSPN. Thus immunoallergy might account, in some cases, for the cutaneous, intestinal and pulmonary signs observed in HSPN, but not in IgAN. We postulate stimulation of IgE-sensitized mast cells by specific antigens in the presence of IgA circulating immune complexes (CIC), release of vasoactive substances, increased capillary permeability and perivascular deposition of IgA CIC.

Glycoconjugates and their antibodies are vital components of host-tumor interaction. This review concentrates on the oncological implications of research concerning the alpha gal triad; the alpha 1-->3 galactosyl epitope (alpha Gal), the enzyme responsible for its construction, alpha 1,3 galactosyl transferase (alpha 1-3GT), and its associated antibody: anti-gal. Alpha gal epitopes, previously assumed to be absent from human tissue, have been demonstrated on several human cancer cell lines, senescent red blood cells, and Graves' disease thyrocytes. Alpha-gal presence on neoplastic lines is correlated with increased metastatic formation in animal models. The mechanisms of human response to these neoantigens are complex, as natural anti-gal antibodies exist in high titers in normal sera, thus predicting immunological recognition of cells expressing alpha gal epitopes. Hypotheses vary regarding the pathogenic contributions of metastasis-associated phenomena such as de novo expression of alpha gal and its unmasking by desialylation. The means by which alpha gal is sporadically expressed in human tissue remain unknown, as the galactosyl transferase which produces this epitope in constitutively expressive animals has undergone significant mutation at the genomic level in humans. Pathological re-expression is presumed to require permissive changes at a cellular level. Detailing these alterations is a prerequisite to the comprehension of the metastatic phenotype. In this context, the possibility of therapeutic strategies affecting alpha gal expression are also discussed. [less ▲]

Expression of Gal alpha 1-3Gal cell surface residues has been correlated with the metastatic potential of murine tumor cells. We report that Gal alpha 1-3Gal residues are expressed at the cell surface of malignant human cancer cells, including four cell lines and 50% of the malignant breast specimens obtained by aspiration biopsy. In contrast, all benign breast biopsies and normal cells were Gal alpha 1-3Gal negative. Affinity-purified anti-alpha-galactosyl IgG (anti-Gal) antibody, which specifically recognizes Gal alpha 1-3Gal residues, significantly inhibited cell attachment in two in vitro assays thought to indicate tumor cell extravasation of the circulatory system during the metastatic process: attachment to perfused human umbilical vein endothelium, and attachment to isolated laminin. Since anti-Gal antibody is a natural component of all human sera, we propose that it may be part of the natural antitumor defense system in humans. [less ▲]

The City promotion project aims at arousing the awareness and possible use of the Very High Resolution (VHR) satellite images in the public agencies and education sector. This project is presently financed by the Belgian federal Office for Scientific, Technical and Cultural affairs (OSTC). Il this purpose, a poster has been prepared showing the three main towns in Belgium _ Brussels, Ghent and Liège - and a website has been devoted to the project. The core of the cities is represented by satellite maps at 1: 5 000 scale. Ikonos panchromatic and multispectral images are merged together in order to obtain coloured images at 1 m resolution able to render the urban fabric of these old cities. Moreover small excerpts at enlarged scale (1: 3 000) show typical places and building in panchromatic mode. The excerpt selected on the famous Brussels “Grand Place” is used to illustrate the fusion process between the panchromatic (1 m) and the multispectral (4 m) images. Two small scale insets present the regional context of these three towns thanks to a natural colour composite made of Landsat 7 ETM+ images on the one hand, and a classical physical map on the other hand. Various exploitations in the classroom of this poster, and others of the same kind, are suggested on the related website (http://www.geo.ulg.ac.be/eduweb). [less ▲]

Superheroes have been supportive of the state’s ideologies for a long time. From WW II to the Cold War era, they have defended the status quo and fought countless enemies of the establishment while showing strong nationalist ideology. Yet, in their long existence, these characters and the narratives they feature in, have been subject to many redefinitions, usually during periods of ideological conflicts such as the Vietnam War or the overtly pro-masculine and pro-war politics of the Reagan era. Following this logic, it seems interesting to raise the question whether or not the superhero genre changed after the events of 9/11 and the subsequent ‘War on Terror.’ This question becomes even more important when one draws a parallel between the Bush administration’s political rhetoric of the early aftermath, and the classical superhero Manichean formula whereby good usually prevails over evil. Whereas early superhero comics engaging with 9/11 presented cases of topical suffering, victimization, and sometimes revenge, later superhero texts have confronted readers with moral and political ambiguities. Indirectly or metaphorically referring to the traumatic events of September 11th and its aftermath, many post-9/11 superhero narratives have called into question the binary dialectic, long sustained by the medium itself, and rearticulated by the Bush administration; they have suggested that America was to some extent responsible for, or at least, implicated in the attacks. In doing so, these texts function as powerful political allegories which challenge America’s sense of moral exceptionalism, the state’s implementation of (inter)national security policies, and by extension, the very sociological role of the superheroic figure. In this paper, I aim to demonstrate how two recent superhero comics’ series – Marvel’s multi-authored cross-over Civil War (2006) and Warren Ellis and Juan Jose Ryp’s Black Summer (2008) – have allegorized the events of 9/11 to critique the above issues in different but related ways. More specifically, I argue that these narratives constitute revisions of traditional superhero texts which problematize the morality of superhero figures, comment on the pervasive effects of the mass media, and ultimately challenge the state’s intervention policies in the face of adversity.

The performance of steel-concrete composite full strength joints endowed with concrete filled tubes, designed with a multi-objective methodology dealing with seismic actions followed by fire is presented in this paper. In detail, instead of a traditional single-objective design where fire safety and seismic safety are independently achieved and the sequence of seismic and fire loading are not taken into account, the proposed design approach guarantees: i) both seismic safety and fire safety with regard to accidental actions; ii) fire safety for at least 15 min fire exposure on a joint characterised by stiffness deterioration and strength degradation due to seismic loading. In order to achieve the multi-objective design, full strength beam-to-composite tubular column joints were designed by means of the component method of Eurocode 4 Part 1-1 and Eurocode 3 Part 1-8, while Eurocode 4 Part 1-2 was considered for fire design. Moreover, to face seismic-induced fire, they were enhanced with specific joint components which will be detailed. Both the experimental program and the results provided by seismic tests, pre-damaged tests and fire tests carried out on beam-to-column joints are presented and discussed. The results emonstrate their adequacy in terms of design and performance. Moreover, non-linear numerical simulations clearly show that these joints can be deemed adequate for moment resisting frames of medium ductility class characterized by a behaviour factor of about 4.

This study summarizes the treatment effect of zoledronic acid infusion on lumbar spine bone mineral density in different subgroups with glucocorticoid-induced osteoporosis. Zoledronic acid is significantly more effective than risedronate in increasing lumbar spine (LS) bone mineral density (BMD) in both prevention and treatment of glucocorticoid-induced osteoporosis. INTRODUCTION: In patients on glucocorticoids, a single zoledronic acid infusion significantly increased BMD versus daily oral risedronate. We assessed treatment effect on LS BMD in different patient subgroups at month 12 that contributed to the risk of osteoporosis in addition to glucocorticoids. METHODS: Patients randomized to a single IV infusion of zoledronic acid 5 mg or risedronate (5 mg/day) and stratified based on glucocorticoids duration [treatment (>3 months) and prevention (</=3 months) subpopulations] were subgrouped by age; gender; menopausal status in women; dose and duration of prednisone during the trial; and baseline serum 25-OH vitamin D, LS BMD T-score, creatinine clearance, and concomitant medication use. RESULTS: At month 12, zoledronic acid significantly increased LS BMD versus risedronate in patients </=74 years (P < 0.05) in the treatment and 65-74 years (P = 0.0008) in the prevention subpopulation. At month 12, zoledronic acid significantly increased LS BMD versus risedronate in both subpopulations irrespective of gender (all P < 0.05), cumulative prednisone dose (all P < 0.01), and postmenopausal status (all P < 0.05). In premenopausal women, in both subpopulations, zoledronic acid significantly increased total hip BMD (all P < 0.05) versus risedronate at month 12 but not LS BMD. Osteoporotic patients in the prevention (P = 0.0189) and osteopenic patients in the treatment subpopulation (P = 0.0305) showed significant LS BMD increases with zoledronic acid versus risedronate at month 12. CONCLUSIONS: This post hoc analysis suggests that zoledronic acid is significantly more effective than risedronate in increasing LS BMD in prevention and treatment of glucocorticoid-induced osteoporosis across a wide range of patients.
