Tracheobronchial squamous metaplasia is common in smokers and is associated with both airway obstruction in chronic obstructive pulmonary disease (COPD) and increased risk of lung cancer. Whereas this reversible epithelial replacement is almost always observed in association with chronic inflammation, the role of inflammatory mediators in the pathogenesis of squamous metaplasia is still unclear. In the present study, we investigated the implication of cigarette smoke-mediated pro-inflammatory cytokine up-regulation in the development and treatment of tracheobronchial epithelial hyperplasia and squamous metaplasia. By using immunohistological techniques, we showed a higher epithelial expression of TNFalpha, IL-1beta and IL-6 as well as an activation of NF-kappaB and AP-1/MAPK signalling pathways in the respiratory tract of smoking patients compared to the normal ciliated epithelium of non-smoking patients. In addition, we demonstrated that these signalling pathways strongly influence the proliferation and the differentiation state of in vitro generated normal human airway epithelial basal cells. Finally, we exposed mice to cigarette smoke for 16 weeks and demonstrated that anti-TNFalpha (etanercept), anti-IL-1beta (anakinra) and/or anti-IL-6R (tocilizumab) therapies significantly reduced epithelial hyperplasia and squamous metaplasia development. These data highlight the importance of soluble inflammatory mediators in the pathogenesis of tracheobronchial squamous metaplasia. Therefore, administration of pro-inflammatory cytokine antagonists may have clinical application in the management of COPD patients. [less ▲]

An anti-inflammatory role and therapeutic potential for cyclopentenone PGs (cyPGs) has been suggested, based on observations that levels of cyPGs in exudates increase during the resolution phase of inflammation, and that exogenous cyPGs may attenuate the inflammatory response in vivo and in vitro mainly through inhibition of NF-kappaB, a critical activator of inflammatory gene expression. However, exogenous cyPGs inhibit NF-kappaB only at concentrations substantially higher than those of endogenous cyPGs present in inflammatory fluids, thus challenging the hypothesis that cyPGs are naturally occurring inhibitors of inflammation and suggesting that cyPGs at low concentrations might have previously unappreciated effects. In this study, using various cell types, we report that cyPGs, when used at concentrations substantially lower than required for NF-kappaB inhibition (viz, low micromolar concentrations), significantly potentiate the inflammatory response to TNF-alpha. At these concentrations, cyPGs induce production of reactive oxygen species, thereby synergizing with TNF-alpha to activate the extracellular signal-regulated kinase 1/2, an activation which in turn potentiates proinflammatory cytokine expression at both transcriptional and posttranscriptional levels. Our studs establishes a proinflammatory role for cyPGs at low micromolar concentrations, raises the possibility that cyPGs do not act as physiologic anti-inflammatory mediators, and questions the therapeutic potential of these compounds.

A first research funded by the Commission of the European Communities has led to a manual design methodology, mainly orientated to the conception of low-cost houses, integrating the fundamental thermal concepts into the design process, without any use of sophisticated technology. The present paper concerns a practical application of this design methodology, used for a project of 25 low-energy houses designed, built and to be monitored. From the first design step until the detailed design, the research team has followed the objective to obtain houses having estimated heating energy needs 50 % lower than commonly, without any investment overrun, even on a difficult North sloped site. The design methodology has been an optimization tool of the volume, the plan, the North and South fenestration, the insulating material, etc. The construction elements were usual (for cost reasons), but their installation has been improved in a manner which allows a continuous control during the construction, giving no the guarantee to obtain thermal properties as close as possible to the expected ones. A detailed monitoring will measure the actual heating energy consumption and thus check the first evaluations. [less ▲]

In this paper, we model a research-and-development project as consisting of several modules, with each module containing one or more activities. We examine how to schedule the activities of such a project in order to maximize the expected profit when the activities have a probability of failure and when an activity’s failure can cause its module and thereby the overall project to fail. A module succeeds when at least one of its constituent activities is successfully executed. All activities are scheduled on a scarce resource that is modeled as a single machine. We describe various policy classes, establish the relationship between the classes, develop exact algorithms to optimize over two different classes (one dynamic program and one branch-and-bound algorithm), and examine the computational performance of the algorithms on two randomly generated instance sets.

Abstract Aim Twice daily dosing is often perceived as inferior to once daily dosing due to a higher likelihood of missing a dose. However, more important is the extent to which drug action is maintained when doses are delayed or missed. We compared the estimated inhibition of platelet aggregation (eIPA) for ticagrelor twice daily and clopidogrel once daily, based on their pharmacokinetic/ pharmacodynamic relationships and patient dosing history data. Methods Drug dosing histories of 5014 patients prescribed cardiovascular medications (primarily antihypertensive medicines) were extracted from an electronically compiled dosing history database. eIPA levels were simulated for 677 twice daily and 677 once daily dosing histories over a 30 day period, based on published onset/offset models for ticagrelor and clopidogrel IPA characteristics. Results While many patients treated twice daily missed at least one dose in 30 days, only 25.7% missed two consecutive doses. By comparison, 46.8% of patients treated once daily missed at least one dose. Simulations based on patient adherence over time showed that the average mean eIPA for ticagrelor twice daily remained significantly higher than for clopidogrel once daily (81.1% vs. 55.0%, P < 0.001). Ticagrelor twice daily patients had an eIPA below 10% for 0.20% of the 30 day period compared with 2.05% for clopidogrel once daily (P = 0.0001). Conclusions The projected level of platelet inhibition remained higher for ticagrelor twice daily than clopidogrel once daily, mainly due to the higher eIPA level achieved with ticagrelor and the relatively low likelihood of missing two consecutive twice daily doses. This modelling and simulation study suggests a therapeutic benefit of ticagrelor over clopidogrel when taking into account the most common dosing omissions. © 2013 The British Pharmacological Society.

We propose to post-process the results of a scenario based stochastic program by projecting its decisions on a parameterized space of policies. By doing so the risk of overfitting to the set of scenarios used in the stochastic program is reduced. A proper choice of the structure of the space of policies allows one to exploit them in the context of novel scenarios, be it for Monte-Carlo based value estimation or for use in real-life conditions. These ideas are presented in the context of planning the exploitation of electric energy resources or for evaluating the economic value of a portfolio of assets. [less ▲]
