Organic farming is considered to be one of the solutions for the problems of sustainability faced today by the agriculutral sector. This paper describes the growth of the Walloon organic sector during the last years thanks to the support of the regional authorities through financial incentives and a new regional strategic development plan. It also presents some results collected during an on-farm survey concerning organic cereals. It appears that organic farming has significantly developed thaks to public support even if the prices of organic products are exceeding by 30% those of conventional products. Organic farming can play a significant role in the future of Walloon agriculture. However, due to the high conversion rate during these last years, it is not guaranteed that the financial support could be conserved at a such level. [less ▲]Detailed reference viewed: 18 (4 ULg)

Objective: A large trial published in 2000 concluded that planned vaginal delivery of term breech births is associated with high neonatal risks. Because the obstetric practices in that study differed from those in Countries where planned vaginal delivery is still common, we conducted an observational prospective study to describe neonatal Outcome according to the planned mode of delivery for term breech births in 2 such countries. Study design: Observational prospective study with an intent-to-treat analysis to compare the groups for which cesarean and vaginal deliveries were planned. Associations between the outcome and planned mode of delivery were controlled for confounding by multivariate analysis. The main outcome measure was a variable that combined fetal and neonatal mortality and severe neonatal morbidity. The study Population consisted of 8105 pregnant women delivering singleton fetuses in breech presentation at term in 138 French and 36 Belgian maternity units. Results: Cesarean delivery was planned for 5579 women (68.8%) and vaginal delivery for 2526 (31.2%). Of the women with planned vaginal deliveries, 1796 delivered vaginally (71.0%). The rate of the combined neonatal outcome measure was low in the overall population (1.59%; 95%, Cl [1.33-1.89]) and in the planned vaginal delivery group (1.60%; 95% CI [1.14-2.17]). It did not differ significantly between the planned vaginal and cesarean delivery groups (unadjusted odds ratio 1.10, 95% CI [0.75-1.61]), even after controlling for confounding variables (adjusted odds ratio 1.40, 95% CI [0.89-2.23]). Conclusion: In places where planned vaginal delivery is a common practice and when strict criteria are met before and during labor, planned vaginal delivery of singleton fetuses in breech presentation at term remains a safe option that can be offered to women.

In Parkinson's disease, altered activity in posterior associative cortices has often been associated with dementia. It remains to be determined if this pattern is a reliable marker of a progression toward dementia in patients without demonstratable dementia. In this retrospective analysis, we used positron emission tomography to study resting-state cerebral fluodeoxyglucose uptake in 8 healthy controls and 8 Parkinson's disease patients who did not have evidence of dementia at the time of assessment. For those patients, clinical follow up was available and we know that they did not meet dementia criteria on average 10,37 years after assessment. The results show that patients had reduced fluodeoxyglucose uptake mostly localised in the right hemisphere and including precuneus, superior temporal, middle temporal and inferior parietal cortices. It also includes right insula. These cerebral activity predominating in posterior cortices is present in non-demened patients but is not always predictive of dementia within the 10,34 years.

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: 29 (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: 36 (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.

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)
