In the present study, we investigated the temporal within-person variability of the exposure biomarker for phthalates, parabens and benzophenone-3 (BP3) in 32 Belgian adults, each providing 11 urine spots during 4 months. We calculated the intraclass coefficient correlation (ICC), the sensitivity and the specificity to assess the temporal reproducibility and to investigate the predictive ability of the spot measurements for these classes of chemicals. Additionally, we explored the temporal variability of the estimation of the cumulative risk of exposure to phthalates (hazard index; HI). We observed fair ICC ranging from 0.55 to 0.68 for parabens, monoethyl phthalate (MEP), mono-iso-butyl phthalate (MiBP) and BP3, but lower ICC, from 0.20 to 0.49, for monobenzyl phthalate (MBzP), mono-n-butyl phthalate (MnBP), mono-2-ethylhexyl phthalate (MEHP), mono-2-ethyl-5-oxo-hexyl phthalate (5-oxo-MEHP) and mono-2-ethyl-5-hydroxy-hexyl phthalate (5-OH-MEHP). The ICC estimated for HI (0.49) reflected a moderate reproducibility. The measurements in spot samples were moderate to good predictor of the 4-month level of exposure for parabens, MEP, MnBP, MiBP, BP3 and HI (sensitivity ranging from 0.67 to 0.77), but lower predictor for MEHP, 5-oxo-MEHP, 5-OH-MEHP and MBzP (sensitivity ranging from 0.58 to 0.63). The sensitivity could be increased when several spot urinary levels were averaged to predict the long-term level of exposure. Globally, our results indicate that a single spot measurement seems to correctly represent the long-term exposure for parabens, BP3, MEP, MiBP and HI. Additional spot samples seemed to be needed for the proper exposure assessment of the other target compounds. [less ▲]

The aim of this paper is to identify differences in genetic variation of fatty acid (FA) composition in milk in different breeds. Data used included Meuse-Rhine-Yssel (MRY) and Holstein Friesian (HF) cattle breeds which were raised in the Netherlands. Both populations participated in the same milk recording system, but differed in selection history, where in the MRY there has been relatively very little emphasis on selection for high-input high-output production systems compared to HF. Differences in genetic variation were investigated by estimating breed specific additive genetic variances and heritabilities for FA contents in milk of MRY and HF. Mid Infrared Spectrometry spectra were used to predict total fat percentage and detailed FA contents in milk (14 individual FA and 14 groups of FA in g of fat/dL of milk). The dataset for MRY contained 2916 records from 2049 registered cows having at least 50% genes of MRY origin and the dataset used for HF contained 155,319 records from 96,315 registered cows having at least 50% genes of HF origin. Variance components of individual FA content in milk for the different breeds were estimated using a single trait animal model. Additive genetic variances for FA produced through de novo synthesis (short chain FA, C12:0, C14:0, and partly C16:0), C14:1 c-9 and C16:1 c-9 were significantly higher (. P<0.001) for HF compared to MRY. Heritabilities of the individual FA, C4:0 to C18:0, for HF ranged from 0.28 to 0.52 and for MRY from 0.17 to 0.34. Heritabilities of the individual C18 unsaturated FA for HF ranged from 0.11 to 0.34 and for MRY from 0.10 to 0.26. Although the mean content in milk for the FA C18:2 c-9, t-11 was low in both breeds, the additive genetic variance in our dataset was significantly higher for MRY (P<0.05) compared to HF. Heritabilities of the groups of FA for HF ranged from 0.19 to 0.53 and for MRY from 0.11 to 0.28. For the majority of the FA, the additive genetic variances for HF were significantly higher compared to MRY, except for most of the poly-unsaturated FA. The results for the poly-unsaturated FA, however, may be affected by the lower accuracy of the predictions for these FA. In conclusion, our results show that the HF breed has substantially larger genetic variance for most FA compared to MRY. © 2015 Elsevier B.V. [less ▲]

The Algerian agricultural sector faces the challenge to meet the food needs of its population despite low agricultural capacity, resulting in increasing pressure on natural resources. This paper aims to inventory the greenhouse gas (GHG) emissions related to livestock sector in the rural area of Chemini (province of Bejaia), taking into account the emissions due to enteric fermentation, in the form of methane, and manure management, in the form of methane and nitrous oxide. Emissions intensity, expressed in CO2- equivalents (CO2-eq) per kg of edible protein, was included in the study. Ruminants contribute to 94% of livestock GHG emissions and to 53% of protein production, with a large share due to cattle. The main part of emissions is related to enteric fermentation. High-producing cattle present the lowest emission intensity of the ruminant category with 24 kg CO2-eq per kg protein. Chickens produce 2.7% of livestock related emissions but provide 47% of animal protein. It results in low emission intensities whereas important difference is noticed between backyard and industrialized systems (around 21 versus 1 kg CO2-eq per kg protein, respectively). Improvement of animal performance should contribute to mitigate the environmental impact of livestock production in Algeria. [less ▲]

The WONCA International Classification Committee (WICC) was set up by the WONCA Council in Melbourne in 1972 on the occasion of the Fifth World Conference (1). WONCA recognized the need for classifying and analysing data derived from clinical encounters with patients that was quite unique to family medicine. This would become increasingly important with the advent of electronic health records. From an initial small group led by Henk Lamberts and Maurice Wood (°), a tool which would become the ICPC was progressively developed and in 1987, the three existing classification systems, the International Classification of Health Problems in Primary Care (ICHPPC-2), ICPC-Process and Reason for Encounter - were merged into a single one; the ICPC. ICPC-2 was published in 1998 by the WONCA International Classification Committee, after several years of revision and cross-mapping with the International Classification of Diseases (ICD) – 10 (2). ICPC-2 is maintained by WICC and an updated version is edited on the site [less ▲]

Clinical prevention, under the influence of public health, has been organised in a chronological manner since the middle of the 20th century. A paradigm shift from a chronological to a constructivist relationship-based preventive pattern of care (1) offers new insight into the practice of doctors, and brings to light the concept of quaternary prevention, a critical look at medical activities with an emphasis on the need not to harm. Quaternary prevention addresses the fundamental question of what constitutes too much or too little medicine. It is the fourth form of disease prevention, but also the fourth frame of action for family doctors. [less ▲]

Ce livre revisite l’histoire de l’art dans ce qu’elle a de plus universel : son rapport au ciel. De l’Orient à l’Occident, de l’Antiquité à l’époque contemporaine, du classique au plus inattendu, il crée un espace singulier où se mêlent art et science, un musée imaginaire croisant sensibilité intime et compréhension du Cosmos, un jeu sans cesse réinventé… car il n’y a pas une seule manière de regarder les étoiles. Bien sûr, le ciel possède un énorme pouvoir évocateur, une force inspiratrice à nulle autre pareille, mais l’inspiration n’est pas la seule des relations entre l’art et l’astronomie. En effet, les artistes peuvent apporter leur grain de sel aux révolutions scientifiques, tandis que l’astronomie peut aider à comprendre certaines œuvres. Avec près de 600 illustrations, cet ouvrage n’a pas pour but d’égrener la liste exhaustive des représentations de ciel étoilé, clair de lune, ambiance crépusculaire ou soleil de midi, mais plutôt d’aborder les multiples relations entre l’art et la science. Il s’agit d’une invitation à un voyage aux frontières mouvantes et incertaines des plus belles réalisations de l’esprit humain. [less ▲]

The pathophysiological mechanisms of tendinopathies integrate various intrinsic and extrinsic factors. Classic «passive» therapeutics have a limited action. Because of a better pathophysiological understanding of tendinopathies, more recent treatments (injections of various compounds, infiltrations of platelet-rich plasma, stem cells) would lead to a longterm healing. In case of failure of conservative managements and depending on the anatomical site, a surgical approach may be considered. [less ▲]

Observations of solar-like oscillations by CoRoT and Kepler space-borne telescopes, have opened new opportunities for the energetic modelling of these oscillations. In particular, oscillations propagating in both the convective envelope and the radiative core of evolved low-mass stars, called mixed-modes, have been detected, allowing us to investigate various physical processes acting on oscillations in these two regions. Theoretical predictions for the linewidths and the amplitudes of solar-like oscillations, as obtained and discussed in this thesis, strongly depend on the treatment of the interaction between convection and oscillations. Observed properties of solar-like oscillations thus gives us the opportunity to test and constrain this treatment. The comparisons between observed and theoretical linewidths of main-sequence stars allow us to constrain the parameters of the time-dependent treatment of convection and to produce more accurate results. The remaining discrepancies will give us new clues for the improvement of the treatment of the interaction between convection and oscillations. The modelling of the energetic aspects of solar-like oscillations in red giants allows us to derive a detectability limit for mixed-modes. These results are in overall good agreement with typical red-giant observed power spectra. A detailed comparison between an observed subgiant and the corresponding theoretical predic- tions confirms that the main aspects of the observed energetic properties of solar-like oscillations are well reproduced by the theoretical modelling. Discrepancies between observed and theoret- ical linewidths of quadrupole mixed-modes lead us to invoke the existence of a new damping mechanism in the core of this star. [less ▲]
