The paper reverse the famous question of Susan Möller Okin "Is multiculturalism bad for women" and asks the question of the supposed "natural alliance" between secularism and democracy. It takes as an illustration the relation between secularist movement and women's claims in the history of Belgium from the Belgian revolution until now. It presents a first, sketchy description of the alliance, trying to show that three periods can be distinguished : until the end of the schoolwar, the relations between the secularist movement and women's claim are rather weak and the secularists tend to distrust women, they consider as allied of the clerics; during the period of 1960-2000, the alliance is stonger over the claim of "self-disposal of one's body'" ; then, from 2000 until now, there is a strong division between both secularist and feminist movements, and so there are two alliances : radical secularism and mainstream feminist movement are allied against islam while, radical feminist and tolerant secularism are allied against neo-colonialist position.

The medial preoptic area (mPOA) is a key site for the dopaminergic enhancement of male sexual behavior. Dopamine release increases in the rat mPOA with mating, supporting the critical stimulatory role played by preoptic dopamine on male sexual behavior. However, it has been questioned whether dopamine is specifically related to the occurrence of male sexual behavior and not simply involved in general arousal. To address this question, we ask whether dopamine release in the mPOA is linked to the production of male sexual behavior in Japanese quail, a species that exhibits a much shorter temporal pattern of copulation than rats and does not have an intromittent organ, resulting in a very different topography of their sexual response. Extracellular samples from the mPOA of adult sexually experienced male quail were collected every six minutes before, during, and after exposure to a female using in vivo microdialysis and analyzed using HPLC-EC. Extracellular dopamine significantly increased in the presence of a female and returned to baseline after removal of the female. However, subjects who failed to copulate did not display this increased release. These findings indicate that it is not solely the presence of a female that drives dopamine release in males, but how a male responds to her. Further, in subjects that copulated, dopamine release did not change in samples collected during periods of no copulation. Together, these findings support the hypothesis that dopamine action in the mPOA is specifically linked to sexual motivation and not only copulatory behavior or physical arousal.

Steroid-16α-hydroxylase activities have been measured in normal and induced rat livers using four different substrates. The male/female activity ratio as well as the induction factor vary with the substrate indicating that steroid-16α-hydroxylase activity is a heterogenous enzyme. Experiments using specific inhibitors led to the conclusion that steroid-16α-hydroxylase is supported by at least two cytochrome P-450 forms, different from the cytochrome P-448.

The territorial sensitivities method was proposed as a tool to collect senses of places and meanings of landscape features. It was presented as an alternative of the traditional participation process to take into account the inhabitants’ meanings in physical planning projects. The method is based on the comparison of an “objective” inventory of localisable changes and those collected in the speech of the inhabitants. Analysing which changes are mentioned but also which ones are absent contributes to grasp the places appropriation. After a short presentation of the method, the paper asks about the acceptability of this one in the context of the territorial intelligence. Is it suitable to join non participative empathic methods in the set of tools of the territorial intelligence? [less ▲]Detailed reference viewed: 32 (10 ULg)

Herbivore insects use a broad range of chemical cues to locate their host to feed or to oviposit. Whether several plant volatiles are effective allelochemicals for insects, the latter also emit molecules which have infochemical role. The (E)-beta-farnesene (EBF) is a well-known aphid alarm pheromone commonly found in all previously tested species. Analysis of the released molecules from 23 aphid species, mainly collected on their natural host plant from May to July, was performed by gas chromatography–mass spectrometry. While EBF was identified as the main volatile substance in 16 species, alone or associated with other molecules, the alarm pheromone was only a minor component of the volatile molecule pattern of five other species. Moreover, two species, Euceraphis punctipennis and Drepanosiphum platanoides, did not release EBF at all but other terpenes were identified. This original observation raised the question on the utility and the source of the non-EBF volatiles. Are these potential infochemical substances produced by the aphid or only absorbed from the host plant? Here we determined that terpenes released by insects were not only provided by the host plants. Indeed, Megoura viciae emitted additional molecules than the ones from several aphid species reared on the same host plant. Moreover, no systematic relation between the feeding behaviour of the aphid species and the volatile releases was observed. Aphid terpene composition and proportion would provide reliable cues to identify the emitting organism, plant or insect. The next step of this work will be to determine the infochemical role of terpenes found in the range of tested aphid samples to better understand the relations between the different tritrophic levels.

The ADA and the EASD recently published a consensus statement for the medical management of hyperglycaemia in patients with type 2 diabetes. The authors advocate initial treatment with metformin monotherapy and lifestyle modification, followed by addition of basal insulin or a sulfonylurea if glycaemic goals are not met (tier 1 recommendations). All other glucose-lowering therapies are relegated to a secondary (tier 2) status and only recommended for selected clinical settings. In our view, this algorithm does not offer physicians and patients the appropriate selection of options to individualise and optimise care with a view to sustained control of blood glucose and reduction both of diabetes complications and cardiovascular risk. This paper critically assesses the basis of the ADA/EASD algorithm and the resulting tiers of treatment options. [less ▲]Detailed reference viewed: 45 (1 ULg)

Objective To determinethe prevalence of spontaneous endometriosis andthe incidence of induced endometriosis after endocervical canal resection in baboons. Design Induction and follow-up of endometriosis in baboons, which is one of the primate species that develop spontaneous endometriosis. Forty-one baboons were checked for the presence of spontaneous endometriosis. We then attempted to induce endometriosis in 30 of them by endocervical canal resection. Setting Institute of Primate Research, Nairobi, Kenya, and Catholic University of Louvain, Brussels, Belgium. Animal(s) Forty-one baboons were checked for spontaneous endometriosis and 30 of them were used to develop a model of induced endometriosis. Intervention(s) A total of 41 baboons underwent diagnostic laparoscopy for 10 months. In a first step, 30 of this number subsequently underwent endocervical canal resection. In a second step, 20 of the 30 underwent uterine horn resection. Main Outcome Measure(s) Follow-up by laparoscopy. Result(s) Two of the 41 baboons were diagnosed with spontaneous endometriosis (4.8%). Twelve months after the surgical procedure to induce endometriosis, 8 of 29 animals presented with endometriotic lesions diagnosed by using laparoscopy and confirmed by histologic examination. The incidence of induced endometriosis in our model was thus 27.6%. In 2 baboons, endometriosis disappeared over time, resulting in a final rate of 20.7% (6/29). Conclusion(s) The rate of spontaneous endometriosis is very low (4.8%). Endometriosis can be induced (with a rate of just 27.6%) by endocervical canal resection to stimulate retrograde menstruation.

The interest in using shrubs and trees as forage for cattle is raising in temperate regions, along with the environmental measures promoting hedges along pasture. This study aimed at determining the influence of the presence of a woody hedge on grazing cattle behavior as well as the evolution of this behavior during the grazing season. Twelve heifers were set to graze a standard ryegrass and clover meadow during the grazing season of 2013. The animals were divided in 2 groups : one with a free access to a hedge composed by 10 temperate shrub and tree species, the other with no access to a hedge (control). Their behavior (grazing, browsing and other activities) was monitored during 14h d-1 replicated 3d week-1 during 3 periods (May, July and September). Results suggest that both season and presence of a hedge have an influence on the behavior of heifers. Grazing, resting and rumination varied between the two groups in each period (P<0.05). The time spent browsing was influenced by the season (P<0.001); the heifers with an access to the hedge could browse 19.3% of the total time in May against 5.9 and 5.4% in July and September. Both control and experimental heifers grazed more with the progressing season, but the animals without the hedge grazed always more than the heifers that could graze and browse (49.6 vs 43.0%). In conclusion, browsing woody species represents a significant part of the time spent for forage ingestion, and variation in this behavior over the whole grazing season requires to investigate the influence of both pasture and browse availability and composition.

HD 195592 is an O-type super-giant star, known as a well-established runaway. Recently, a Fermi gamma-ray source (2FGL J2030.7+4417) with a position compatible with that of HD 195592 has been reported. Our goal is to explore the scenario where HD 195592 is the counterpart of the Fermi gamma-ray source modeling the non-thermal emission produced in the bowshock of the runaway star. We calculate the spectral energy distribution of the radiation produced in the bowshock of HD 195592 and we compare it with Fermi observations of 2FGL J2030.7+4417. We present relativistic particle losses and the resulting radiation of the bowshock of HD 195592 and show that the latter is compatible with the detected gamma-ray emission. We conclude that the Fermi source 2FGL J2030.7+4417 might be produced, under some energetic assumptions, by inverse Compton up-scattering of photons from the heated dust in the bowshock of the runaway star. HD 195592 might therefore be the very first object detected belonging to the category of gamma-ray emitting runaway massive stars, whose existence has been recently predicted.

Although migraineurs appear in general to be hypersensitive to external stimuli, they maybe also have increased daytime sleepiness and complain of fatigue. Neurophisiological studies between attacks have shown that for a number of different sensory modalities the migrainous brain is characterised by a lack of habituation of evoked responses. Whether this is due to increased cortical hyperexcitability, possibly due to decreased inhibition, or to an abnormal responsivity of the cortex due a decreased preactivation level remains disputed. Studies using transcranial magnetic stimulation in particular have yielded contradictory results. We will review here the available data on cortical excitability obtained with different methodological approaches in patients over the migraine cycle. We will show that these data congruently indicate that the sensory cortices of migraineurs react excessively to repetitive, but not to single, stimuli and that the controversy above hyper- versus hypo-excitability is merely a semantic misunderstanding. Describing the migrainous brain as 'hyperresponsive' would fit most of the available data. Deciphering the precise cellular and molecular underpinnings of this hyperresponsivity remains a challenge for future research. We propose, as a working hypothesis, that a thalamo-cortical dysrhythmia might be the culprit. [less ▲]Detailed reference viewed: 24 (0 ULg)

To detect the possible mechanisms of salt sensitivity, blood pressure (BP), renal biological and red blood cell (RBC) ionic fluxes, responses were studied in 20 normotensive males (<30 years old), after acute isotonie saline infusion (1 litre in less than 30 min). Salt sensitivity was considered to be present if mean supine BP increased by more than 9 mmHg when the salt diet, which was applied each time for 1 week, increased from less than 20 mmol/l NaCI per day to more than 340 mmol/l. Three subgroups were defined: eight salt-sensitives (SS), 10 salt-resistants (SR) and two patients with only a very slight BP increase. ln each group (SS or SR), the same percentage of family history of hypertension was noted (60%). During the normal diet (± 170 mmol/l NaCl per day), vascular resistances were lower , and creatinine clearance higher in SS (26 ± 8 units, and 122 ± 6 ml/min, respectively) than in SR (48 ± 1 units and 102 ± 1 ml/min). As other markers of greater salt overloading could not be detected in SS, these differences could be due to higher cardiac volume ejection in SS than in SR (heart rate was the same in the two populations. During acute salt loading, mean BP rase in SS (tram 88 ± 6 to 93 ± 7 mmHg), while it decreased in SR (from 85 ± 10 to 81 ± 10 mmHg, P < 0.05). During the same period RBC Na+K+-ATPase activity decreased more in SS (from 3970 ± 715 to 3312 ± 452 umol/l cell per h) than in SR (from 4430 ± 550 to 4300 ± 520). Moreover, during chronic oral salt loading (> 340 mmol/l NaCl per day) , SS showed a greater BP increase during noradrenaline (NE) infusion (10 ± 6 mmHg for 60 ng/min per kg NA) than in SR (5 ± 3 mmHg, P < 0.02). In conclusion, salt sensitivity is already present in young normotensives. It could be due to a higher sympathetic venous tone , which in turn would increase cardiac output and secretio n of a plasma Na+K+-pump inhibitor. [less ▲]Detailed reference viewed: 10 (0 ULg)

In archeometry, the non-destructive characteristic of an analytical method is always very attractive. For most of techniques, besides the need of sampling, difficulties can originate from the shape and the size of the silver artifacts to be analyzed. The external PIXE method should be an answer to this problem but several questions are arising from the implementation of the technique to such a material. The aim of this paper is to specify the experimental procedure as to take into account several parameters, which could induce dramatic errors. Among them it can be pointed out the superficial enrichment in silver, arising from the dissolution of copper and copper oxide, the surface roughness effects, the great importance of the stability of the geometric conditions. The accuracy and the precision of the method are considered within the scope of the results obtained in ancient times by the cupellation with ashbone cupels. In addition. the process involved to obtain silver alloys has been studied in order to define its influence on the real fineness of the objects. (C) 2000 Elsevier Science B.V. All rights reserved.

The aim of this experiment is to examine how recollection and familiarity change over time and whether there is a qualitative difference between familiar items that were previously recollected and items that have always been familiar. It might be that, when an item is initially recollected and becomes just familiar after a delay, this form of familiarity is actually a weak and partial recollection, qualitatively different from mere familiarity. To address this issue, a task have been developed in which, at study, participants encoded two series of 100 pictures representing scenes under respectively shallow and deep encoding conditions. Memory for these pictures was tested by means of a yes-no recognition test. Recognised items were classified as recollected or as familiar. Half of the pictures from each encoding condition were tested after 10 minutes and the other half were tested after 2 days. The results indicated that recollection decreased after 2 days while familiarity increased (deep encoding condition) or did not change (shallow encoding condition). This suggests that, among the items judged as familiar after 2 days, some items would have been recollected after 10 minutes and some were initially already familiar. Because deep encoding produced a higher proportion of recollection at the 10-minute interval, the proportion of recollection-changed-into-familiarity responses should be greater in this condition than in the shallow encoding condition. Whether there is a qualitative difference between these responses and pure familiarity responses should be explored in a fMRI experiment. [less ▲]Detailed reference viewed: 19 (0 ULg)

Limnothrissa miodon, a small pelagic clupeid fish introduced at the end of the 1950s into Lake Kivu, became an important resource for the human populations of this area. The total stock of pelagic fish populations of this lake was estimated in 2008 by two hydroacoustic surveys, using an EK60 split-beam sounder (frequency 70. kHz). The total fish stocks were estimated to be approximately 5000. t in the rainy season and 6000 tons in the dry season. These values are similar to previous estimations performed in the 1980s. During 2008, the stock did not fluctuate throughout the seasons; however, the spatial distributions were different in the two hydrological seasons. Interestingly, the L. miodon stock has appeared to remain stable over the last two decades, which suggests that the pelagic fishery in Lake Kivu has not been overexploited and that it is sustainable. © 2012 Elsevier B.V.
