Introduction: In Joint Hypermobility Syndromes, chronic pain is the most disabling symptom. Its origin can be multiple (i.e. subluxations, sprains, pathologies of tendons, ligaments, peripheral nerves, multiple operations). The goal of this article was intended to discuss appropriate physiotherapy in hyperlax patients. Patients and Method: The recovery process was analyzed in three cases (Marfan Syndrome, Ehlers-Danlos Syndrome and Osteogenesis Imperfecta). Hypermobility was assessed using the Brighton scale, pain using the Visual Analogue Scale and quality of life using the Medical Outcome Study Short Form-36. Bone density was evaluated by QDR X-ray absorptiometry. We emphasized that it was important to avoid stretching and to train the patient within a controlled range of motion. Submaximal eccentric exercises within a safe range of motion were incorporated to increase the active control of the joint positioning. Thus, in one patient, isokinetic rehabilitation was successfully undertaken. Each treatment had to be adapted to the individual patient and had to include specific home exercises. Conclusion: In each case, physiotherapy gave good results in relation to pain, quality of life and stability of rehabilitated joints. Safety must be assured and specific evaluations such osteodensitometry, cardiac explorations and interventions of bracing, proprioceptive and functional strengthening can be very helpful. [less ▲]

This document is a kind of Physics formula's form. It is majoritarly coming from a volonty of classifying these last so they are easily accessible. Firstly, this document was redacted in order to be prepared to the engineering studies (at ULg). For this reason, the text has not been very developped, so this document is as short (and quick) as possible, with no need to read unnecessary sentences which would slow the reading. Principal sentences have been written, to make links, because Physics is not only formula's: speaking is a very important way to communicate ideas and to link concepts, especially in Sciences. This document is the minimum minimorum that is given in first degree of Computer Sciences at the University of Liège; some notions also come from the Civil Engineers' course (of this same university). Only few proves will be made, to lighten the document; however, formula's will be admitted. Many different notations will be used for the same idea, in order to give the habit of the reader to use different notations (e.g. $U$ or $V$ in $V=RI$). This synthesis is not comprehensive, and does not pretend to be rigourous. Only the essential chapters and sections have been kept. When prerequisites are necessary, they are announced. Indeed, many points are supposed to be known: this document consists only in a set of reminds! It is clear that the reading of this document needs some basical math. knowledge. A summary of the most important notions is ML_SM2009, from the same author. [less ▲]

The chemical composition of total alkaloids from leaves and roots of Guiera senegalensis was investigated. Three beta-carboline alkaloids were purified: in addition to harman and tetrahydroharman, known in roots and leaves. harmalan (dihydroharman) was isolated for the first time from roots of Guiera senegalensis. Guieranone A, a naphthyl butenone, was also purified from leaves and roots. The in vitro antiplasmodial activity and the cytotoxicity of extracts and pure compounds were evaluated. Each total alkaloid extract and beta-carboline alkaloids presented an interesting antiplasmodial activity associated with a low cytotoxicity. Harmalan was less active than harman and tetrahydroharman. Guieranone A showed a strong antiplasmodial activity associated with a high cytotoxicity toward human monocytes. Its cytotoxicity was performed against two cancer cell lines and normal skin fibroblasts in order to study its anticancer potential: guieranone A presented a strong cytotoxicity against each cell strains. Finally, we evaluated the potent synergistic antimalarial interaction between Guiera senegalensis and two plants commonly associated in traditional remedies: Mitragyna inermis and Pavetta crassipes. Three associations evaluated were additive. A synergistic effect was shown between total alkaloids extracted from leaves of Guiera senegalensis and those of Mitragyna inermis. This result justified the traditional use of the plants in combination to treat malaria. (c) 2006 Elsevier Ireland Ltd. All rights reserved. [less ▲]

We determined the spatial and temporal dynamics of major phytoplankton groups in relation to biogeochemical and physical variables during the late spring coccolithophore blooms (May-June) along and across the continental margin of the northern Bay of Biscay (2006-2008). Photosynthetic biomass (Chla) of the dominant plankton groups was determined by CHEMTAX analysis of HPLC pigment signatures. We used uni- and multivariate statistical techniques to identify the main physical and biogeochemical variables underlying the variation in phytoplankton biomass and community structure. Phytoplankton standing stock biomass varied substantially between and during the campaigns (areal Chla (mg Chla m-2) in June 2006: 63.8 ± 26.5, May 2007: 27.9 ± 8.4, and May 2008: 41.3 ± 21.8), reflecting the different prevailing weather, irradiance, and sea surface temperature conditions between the campaigns. Coccolithophores, represented mainly by Emiliania huxleyi, and diatoms were the dominant phytoplankton groups, with a maximal contribution of, respectively, 72% and 89% of the total Chla. Prasinophytes, dinoflagellates, and chrysophytes often co-occurred during coccolithophorid blooms, while diatoms dominated the phytoplankton biomass independently of the abundance of other groups. The location of the stations on the shelf or on the slope side of the continental margin did not influence the biomass and the composition of the phytoplankton community despite significantly stronger water column stratification and lower nutrient concentrations on the shelf. The alternation between diatom and coccolithophorid blooms of similar biomasses, following the mostly diatom-dominated main spring bloom, was partly driven by changes in nutrient stoichiometry (N:P and dSi:N). High concentrations of transparent exopolymer particles (TEP) were associated with stratified, coccolithophore-rich water masses, which probably originated from the slope of the continental margin and warmed during advection onto the shelf. Although we did not determine the proportion of export production attributed to phytoplankton groups, the abundance of coccolithophores, TEP, and coccoliths may affect the carbon export efficiency through increased sinking rates of particles formed by aggregation of TEP and coccoliths.
