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 ▲]

During heart surgery, several humoral cascades (coagulation, complement, kallicrein-kinin, cytokines, fibrinolysis) and several cell systems (platelets, neutrophils, endothelial cells, ...) are activated. Numerous contributing factors have been reported: blood contact with foreign surfaces of the extracorporeal circuits, blood-air interface, lung and myocardial ischemia-reperfusion after unclamping, hypothermia, shear stresses, ... A post-perfusion syndrome may develop which include miscellaneous symptoms: coagulation disturbances and bleeding, neurological alterations, inflammatory syndrome, and, in extreme cases, multisystemic organ failure. Even if the present mortality of cardiac surgery is low, several approaches have been proposed to reduce such activations. They are based on changing in the circuit design, or in the composition of the luminal surfaces of the tubing and oxygenator, on improvement of the operative technique, and on modifications of the perfusion technique. Pharmacological agents are also used (anti-inflammatory drugs, corticoids, serine proteases inhibitor (aprotinin, ...). Nevertheless, the development of more biocompatible surfaces seems a promising goal. [less ▲]
