The atom transfer radical polymn. of Me methacrylate was studied in the presence of 6 novel homo- and heterobimetallic Ru complexes: (p-cymene)RuCl2/(PCy3)(ethylene)RuCl2, (p-cymene)RuCl2/(1,3-Mes2-4,5-X2-imidazolin-2-ylidene)(ethylene)RuCl2 (X = H or Cl, Mes = 2,4,6-trimethylphenyl), and (p-cymene)RuCl2/[(2-dicyclohexylphosphinoethyl)cyclopentadienyl](Cp)TiX2 (X = F, Cl, or OBz). Et 2-bromoisobutyrate was used as initiator in all expts. All catalysts showed high efficiency in controlled synthesis of poly(Me methacrylate). Using the ruthenium/titanocene dibenzoate complex, the polymn. stopped after a few hours of reaction, affording nevertheless a polymer with a decent polydispersity. [less ▲]

This poster aims to study the same-sex relationships in two radically different socio-legal contexts (Belgium and Italy). In particular, it highlights the links between the romantic attachment style, the internalized homophobia, the social support and the desire and intent of parenthood. The sample is composed by 120 young homosexual people (60 Belgian and 60 Italian), each sub-group is stratified into 2 equal groups according to gender (30 men and 30 women) and to the relational status (30 singles and 30 in a current relationship). Some significant correlations and differences between these groups have been demonstrated, allowing a better understanding of the way to live a relationship and the desire of parenthood among homosexual people.

In vivo experiments on tomato (Lycopersicon esculentum) roots have been performed: drench of 10-day hydroponic cultures with bacterial suspensions. A second identical treatment was applied one week later and after 30 days of culture, the plants were collected and the bacteria detached from a precise weight of roots were diluted, plated and counted. The mutant devoid of both GalM and PBP4a (encoded by the galM and dacC operon) is affected in its capacity to colonize the tomato roots. [less ▲]

Cell surface heparan sulfate serves as the initial receptor for several alphaherpesviruses and at least one betaherpesvirus. This study shows that during the process of adsorption of the gammaherpesvirus bovine herpesvirus 4 (BHV-4), the viral glycoprotein gp8 interacts with heparinlike moieties of cell surface. This conclusion is based on the following findings. (i) Soluble heparin was capable of blocking BHV-4 infection of Georgia bovine kidney cells by inhibition of viral attachment. (ii) Nevertheless, after virus adsorption to Georgia bovine kidney cells, heparin was partially capable of removing adsorbed virus. (iii) Enzymatic digestion of cell surface heparan sulfate but not of chondroitin sulfates A, B, and C reduced the binding of the virus to the cells, and rendered the cells partially resistant to infection. (iv) Radiolabeled purified BHV-4 bound to wild-type Chinese hamster ovary cells, whereas binding of the virus to mutant Chinese hamster ovary cell lines that where deficient in either all glycosaminoglycans or only heparan sulfate was significantly impaired. (v) Using heparin-affinity chromatography, gp8 glycoprotein was shown to bind specifically to immobilized heparin and to elute in the presence of soluble heparin. These data together showed that the gammaherpesvirus BHV-4, like alphaherpesviruses and one betaherpesvirus, adsorbs to cells by binding to cell surface heparin-like moieties. Therefore, this study extends the group of herpesviruses interacting with heparinlike moieties at the cell surface to a member of the gammaherpesvirinae subfamily. [less ▲]

The attachment to and synthesis of collagen by hepatocytes isolated from rats with and without hepatic fibrosis were studied. Attachment of normal hepatocytes was enhanced fourfold in the presence of serum, whereas attachment of hepatocytes from CCl4-treated rats with severely fibrotic livers was enhanced only twofold by serum. Fibronectin promoted hepatocyte attachment to collagen to the same degree as serum, whereas serum from which the fibronectin had been removed did not. Thus hepatocytes adhere to collagen via fibronectin, a known adhesion protein for fibroblasts. In the absence of serum or fibronectin, hepatocytes attached best to basement membrane collagen (type IV). This enhanced attachment was abolished by periodate oxidation of the collagen, an observation which suggested that carbohydrate residues are involved in hepatocyte attachment to this collagen. Collagen synthesis was determined after hepatocytes were cultured for 24 hr. No difference was found in the amount of collagen synthesized by cultures of hepatocytes derived from control rats and from rats with hepatic fibrosis. By immunofluorescence, the cell responsible for the synthesis of collagen appeared to have a fibroblastic morphology. [less ▲]

Plant defensive strategies bring into play blends of compounds dependent on the type of attacker and coming from different synthesis pathways. Interest in the field is mainly focused on volatile organic compounds (VOCs) and jasmonic acid (JA). By contrast, little is known about the oxidized polyunsaturated fatty acids (PUFAs), such as PUFA-hydroperoxides, PUFA-hydroxides, or PUFA-ketones. PUFA-hydroperoxides and their derivatives might be involved in stress response and show antimicrobial activities. Hydroperoxides are also precursors of JA and some volatile compounds. In this paper, the differential biochemical response of a plant against insects with distinct feeding behaviours is characterized not only in terms of VOC signature and JA profile but also in terms of their precursors synthesized through the lipoxygenase (LOX)-pathway at the early stage of the plant response. For this purpose, two leading pests of potato with distinct feeding behaviours were used: the Colorado Potato Beetle (Leptinotarsa decemlineata Say), a chewing herbivore, and the Green Peach Aphid (Myzus persicae Sulzer), a piercing-sucking insect. The volatile signatures identified clearly differ in function with the feeding behaviour of the attacker and the aphid, which causes the smaller damages, triggers the emission of a higher number of volatiles. In addition, 9-LOX products, which are usually associated with defence against pathogens, were exclusively activated by aphid attack. Furthermore, a correlation between volatiles and JA accumulation and the evolution of their precursors was determined. Finally, the role of the insect itself on the plant response after insect infestation was highlighted. [less ▲]

The Differentiated Services (DiffServ or DS) framework takes an edge over IntServ because it is scalable and lesser complex. On the other hand, the application level end-to-end quality o f service, in DiffServ, may get compromised because: 1) network resources are not allocated at microflow level (a data stream pertaining to a single connection) but at aggregate level (collection of one or more microflows), 2) the DiffServ working group does not specify algorithms for PHBs but their output behavio urs and 3) end-to-end quality is function of Service Level Agreements (SLAs) between the adjacent domains transited by the connection and a large diversity in SLAs is quite evident as each DS domain would have different service provision policies. We focus, in this paper, on the first two issues. Our goal is to ha ve DiffServ deployed with all its simplicity and still be able to provide application level end-to-end qu ality of service. For that, we study a PHB for AF classes. A PHB comprises a packet scheduler and a packe t accept/discard algorithm. For packet scheduler, we use the Extended-VirtualClock (Ex-VC) algorithm. Ex-VC perfo rms delay-based service differentiation among the aggregates while selecting a packet for service. The reasons for having delay-based definition for service differentiation are: it is adaptable to load per aggr egate and it does not need to be microflow aware. Other definitions like bandwidth and loss may also be u sed but the former requires microflow aware management and the latter lacks in simplicity. For packet accept/discard algorithm, we use RED when all packets have the same drop precedence level and DI-RO (Deterministic for In-RED for Out) when packets are policed at the ingress DS node and packets viol ating the Service Level Agreement (SLA) are marked OUT. In DI-RO, IN packets are always accepted (except buffer overflow) whereas OUT packets are accepted probabilistically. [less ▲]

INTRODUCTION: Wegener's granulomatosis (WG) is a systemic necrotizing vasculitis associated with c-ANCA antibodies. The involvement of the central nervous system in WG is uncommon and usually caused by in situ vasculitis, intracranial granuloma formation or contiguous invasion from extracranial sites. CASE REPORT: Here, we report on a tumour-like expansion of a severe nasosinusal WG into the brain, which was confirmed by brain biopsy examination. CONCLUSION: The positivity of positron emission tomography in our observation supports the potential role of such functional imaging in the staging, as well as in the follow-up of WG. [less ▲]
