The Greenland ice sheet is projected to be strongly affected by global warming. These projections are either issued from downscaling methods (such as Regional Climate Models) or they come directly from General Circulation Models (GCMs). In this context, it is necessary to evaluate the accuracy of the daily atmospheric circulation simulated by the GCMs, since it is used as forcing for downscaling methods. Thus, we use an automatic circulation type classification based on two indices (Euclidean distance and Spearman rank correlation using the daily 500 hPa geopotential height) to evaluate the ability of the GCMs from both CMIP3 and CMIP5 databases to simulate the main circulation types over Greenland during summer. For each circulation type, the GCMs are compared to three reanalysis datasets on the basis of their frequency and persistence differences. For the current climate (1961–1990), we show that most of the GCMs do not reproduce the expected frequency and the persistence of the circulation types and that they simulate poorly the observed daily variability of the general circulation. Only a few GCMs can be used as reliable forcings for downscaling methods over Greenland. Finally, when applying the same approach to the future projections of the GCMs, no significant change in the atmospheric circulation over Greenland is detected, besides a generalised increase of the geopotential height due to a uniform warming of the atmosphere.

The similarities between patients with untreated growth hormone (GH) deficiency and those with the cardiometabolic syndrome and the beneficial effects of recombinant human GH (rhGH) on body composition have led to the hypothesis that rhGH treatment may have utility in obesity. GH release is reduced in the setting of obesity, primarily due to hyperinsulinism and increased free fatty acid levels. We reviewed the outcomes of 23 clinical studies carried out between 1987 and 2006 that examined the effects of rhGH administration in the obese state. Typically, changes in overall body weight do not occur with rhGH therapy; however, assessment of body composition demonstrates reductions in visceral abdominal fat. Data on the effects of rhGH on lipid and carbohydrate metabolic profiles in obese patients are less clear-cut, with a subset of studies showing a beneficial effect and others a neutral effect. Given the increasing burden of obesity in the general population and the current paucity of effective therapies, it is useful to consider the data on rhGH and obesity from a clinical perspective to highlight potential treatment strategies that harness the somatotropic axis.

The concept of groundwater vulnerability is a useful tool for environmental planning and decision-making. Many different methods have been developed for assessing this vulnerability. Hydrogeologists have failed to reach a consensus concerning the definitions of and reference terms for groundwater vulnerability assessment. Therefore, a review of vulnerability assessment and mapping methods providing a new classification system is necessary. This is focused on techniques that use the overlay and index class methods. New research challenges in vulnerability assessment are identified, especially the need for developing dynamic links between numerical models and overlay and index methods. [less ▲]

This paper reports on an investigations of a series of compounds of the NOy family, based on high resolution infrared solar observations made at the ISSJ (International Scientific Station of the Jungfraujoch), Switzerland (46.55ºN, 7.99ºE, 3580 m a.s.l.). These observations are part of a long-term monitoring effort undertaken by the Liège group since the mid-1970s, and integrated more recently as a contribution to the Network for the Detection of Stratospheric Change (NDSC). Currently, vertical column abundances of over 20 molecules are retrieved from solar spectra recorded under clear sky conditions as regularly as possible, using two high resolution Fourier transform infrared (2 to 15 microns) spectrometers.

The use of the three classical beta-lactamase inhibitors (clavulanic acid, tazobactam, sulbactam) in combination with beta-lactam antibiotics is currently the most successful strategy to combat the beta-lactamase mediated resistance. However, these inhibitors are efficient in inactivating class A beta-lactamases only and the efficiency of the inhibitor/antibiotic combination can be compromised by several mechanisms among which the production of naturally resistant class B or class D enzymes, the hyperproduction of AmpC or even the production of evolved inhibitor-resistant class A enzymes. There is thus an urgent need in the development of novel inhibitors. For serine active enzymes (classes A, C and D), derivatives of the beta-lactam ring such as 6-beta-halogenopenicillanates, beta-lactam sulfones, penems and oxapenems, monobactams or trinems seem to be potential starting points to design efficient molecules (among which AM-112 and LK-157). Moreover, a promising non-beta-lactam molecule, NXL-104 is now under clinical trial. In contrast, an ideal inhibitor of metallo-beta-lactamases (class B) remains to be found, despite the huge number of potential molecules already described (biphenyl tetrazoles, cysteinyl peptides, mercaptocarboxylates, succinic acid derivatives, etc). The search for such an inhibitor is complicated by the absence of a covalent intermediate in their catalytic mechanisms and the fact that beta-lactam derivatives often behave as substrates rather than as inhibitors. Currently, the most promising broad spectrum inhibitors of class B enzymes are molecules presenting chelating groups (thiols, carboxylates, etc) combined with an aromatic group. This review describes all the types of molecules already tested as potential beta-lactamase inhibitors and thus constitutes an update of the current status in beta-lactamase inhibitor discovery.

This contribution to the Re-thinking of Belgium attempts to share our position on the current and future regulation of utilities in our country. We deliberately opt not to offer an exhaustive list of regulatory challenges based on thorough economic analysis. Our main goal is to participate in a welcomed open reform debate. The main messages are that we need (i) more stable and thought- through policy visions resulting from sound economics, clearer roles for all actors involved, more coordination between regulators and (ii) less dependent regulators, less regulatory creep and fewer unnecessary low-powered incentive schemes.

Abstract Background: Osteoporosis affects millions of postmenopausal women worldwide. Osteoporosis-related fractures can lead to chronic pain, disability, systemic complications, and increased risk of recurrent fractures, resulting in increased healthcare costs and mortality. Because currently available therapies have unique benefit/risk profiles, challenges remain in selecting the most appropriate treatment for each osteoporotic woman. Research and Results: Bazedoxifene (BZA), a new selective estrogen receptor modulator, is being developed for postmenopausal osteoporosis. In a 3-year, global, phase 3 study, BZA significantly reduced the risk of new vertebral fractures and nonvertebral fractures in women with higher baseline fracture risk compared with placebo. In 2 extensions of this study, the efficacy of BZA in reducing vertebral fracture risk was sustained over 7 years. BZA improved lumbar spine and total hip bone mineral density compared with placebo at 3 and 5 years, and demonstrated a favorable safety/tolerability profile, with no endometrial or breast stimulation. BZA was cost-effective compared with raloxifene in a 3-year, head-to-head comparative trial. Indirect comparisons further suggest that BZA may be as effective as bisphosphonates in reducing risk of nonvertebral fractures in women at high risk of fracture. BZA demonstrated efficacy and safety for treating postmenopausal osteoporosis over 7 years, particularly in women at a higher fracture risk. Conclusion: Because of its specific pharmacologic profile, BZA may be appropriate for postmenopausal women seeking a tolerable, safe, effective, and cost-effective long-term osteoporosis treatment.

Since 1993, Belgium is officially a federal state, composed of – three – communities and – three – regions, as the – new at the time – first article of the Constitution proclaims. The history of federalism in Belgium is therefore quite recent. Nevertheless, the story is – much – longer since it starts with the independence of Belgium from the United Kingdom of the Netherlands in 1830 . The very beginning of a state and the underlying causes of its creation, as well as its place on the map, the timing of its creation and the characteristics of the elites who take the lead and define the new state’s nature are of crucial importance and these elements shape the country’s political development for centuries . Nonetheless, although the beginning of any state sets up a path dependency , there are also critical junctures along its political development which in turn influences the course of history. This is especially true for Belgium . Here, history and politics are intrinsically interrelated. Indeed, the current challenges on the Belgian federalism find their roots in the country’s history. Three main challenges face Belgian federalism: an ethno-territorial challenge, a socio-economic challenge and a political challenge, that is to say the future of the country itself. In this endeavour to assess the current challenges on the Belgian federalism, three variables have to be taken into account. The first variable is the territorial principle vs. personal principle debate, which constitutes the backbone of the so-called Belgian community question; it is also intrinsically related to the first challenge: the ethno-territorial challenge. The second variable is the political parties because they have played and play the major role in Belgian politics and therefore in the Belgian federal dynamics. The third variable is made of the people; that is, at the individual level, the inhabitants or the citizens or the voters and, at the collective level, the language groups of Belgium. These three variables are at the heart of Belgium’s past, present and future and continuously interact with one another. In order to offer a clear picture of these interactions, Belgium’s history is conceptually divided into three periods: before federalism (1830-1960), federalism (1960-2007) and after federalism (2007-onwards). These three periods shed light on the background of the current challenges on the Belgian federalism. On this basis, the recent institutional agreement which gives Belgium her sixth reform of the state is analyzed as it provides – tentative – answers to the first two challenges. This all leads to the last challenge – the end of Belgium? – dealt with in the conclusion. [less ▲]

The aim of this chapter is to revise some common views on changes in pubertal timing. This revision is based on recent epidemiological findings on the clinical indicators of pubertal timing and data on environmental factor effects and underlying mechanisms. A current advancement in timing of female puberty is usually emphasized. It appears, however, that timing is also changing in males. Moreover, the changes are towards earliness for initial pubertal stages and towards lateness for final stages in both sexes. Such observations indicate the complexity of environmental influences on pubertal timing. The mechanisms of changes in pubertal timing may involve both the central neuroendocrine control and peripheral effects at tissues targeted by gonadal steroids. While sufficient energy availability is a clue to the mechanism of pubertal development, changes in the control of both energy balance and reproduction may vary under the influence of common determinants such as endocrine-disrupting chemicals (EDCs). These effects can take place right before puberty as well as much earlier, during fetal and neonatal life. Finally, environmental factors can interact with genetic factors in determining changes in pubertal timing. Therefore, the variance in pubertal timing is no longer to be considered under absolutely separate control by environmental and genetic determinants. Some recommendations are provided for evaluation of EDC impact in the management of pubertal disorders and for possible reduction of EDC exposure along the precautionary principle. [less ▲]

As the incidence of breast cancer increases, breast reconstruction is more and more often proposed and its indications are viewed in terms of quality of life. In the past, delayed reconstruction was the rule. Progress in reconstructive techniques currently allows performing immediate reconstruction in selected cases, even when the operative field has to be irradiated. These new techniques generally improve the result of breast reconstruction. Moreover, expansion of screening techniques allows detection of small tumors for which a conservative excision is sufficient. Nevertheless, this kind of less aggressive surgery may require a reconstructive procedure in order to maximise the aesthetic result. [less ▲]
