In Belgium, as generally in Europe, the dominant position of the high producing commercial strains specialized in meat or eggs production threats of extinction the local traditional breeds. In this work, a follow up of the changes in populations size, and the rates of inbreeding of the Belgian poultry breeds, has been carried out in 2005 and 2010. About forty breeds were concerned. The Belgian hen breeds being overwhelmingly under threat of extinction, because of the low number of individuals by breed. For each of these breeds, various criteria were considered, risk status, breeding male to breeding female ratio, effective population size, effective population size to actual size ratio and rate of inbreeding.

If lifestyle changes are not effective for maintaining glycaemic control, metformin is recommended as the first glucose-lowering drug to use in a patient with type 2 diabetes, if the patient has no contraindications—eg, renal impairment or hypoxic disorders.1 However, the glucose-lowering response to metformin can vary greatly between patients, with some people responding poorly to this biguanide. Because of the well known therapeutic inertia with respect to pharmacological treatment of diabetes, insufficient glucose control might persist for a long time before any treatment adjustment is made in people who respond poorly to metformin monotherapy.

Dans le Maghreb, les barrages souffrent régulièrement d’un envasement excessif lié aux problèmes d’érosion présent dans les impluviums situés en amont des barrages. Les origines de cette érosion sont multiples : aménagement du territoire, déforestation, affectation des terres,… L’hydrologie couplée aux systèmes d’informations géographiques permet à l’aide de modèles distribués et physiquement basés de prédire l’évolution de l’envasement des barrages. L’application de ces modèles en Algérie permettra à terme, de prédire l’impact d’aménagement anti érosifs, de schémas d’aménagement du territoire sur l’envasement des barrages en estimant précisément la quantité de sédiments produit par l’érosion par ruissellement ainsi que le taux de remplissage. Une méthodologie basée sur les données cartographiques (modèle numérique de terrain, carte pédologie, carte géologie et la cartographie d’occupation du sol) ainsi que les données météorologiques journalières (température, humidité relative, vitesse du vent, radiation solaire) est en cours d’élaboration et de test sur le barrage de Bourkourdane. Cette méthodologie utilise le modèles SWAT Le modèle SWAT est utilisé pour prédire la quantité de sédiment s’accumulant dans le barrage, les flux hydriques débit entrants, sortants, ainsi que les volumes d’eau et de sédiments stockés dans le barrage. Une gestion adéquates des lâchers, couplée à une meilleure gestion de l’érosion en amont du barrage permettra d’allonger la durée de vie des barrages Algériens. Plus particulièrement pour le barrage de Boukourdane, une amélioration de la gestion des lâchers est primordiale pour améliorer la recharge de la nappe, lutter contre l’intrusion des eaux marines, et prévenir l’accumulation des particules fines qui réduisent la perméabilité du sol.

Recently, matrix‐assisted laser desorption/ionization mass spectrometry imaging (MALDI MSI) has emerged as a powerful technique to study the distribution of lipids. However, quantification still remains a challenge because the MALDI signal is strongly affected by ion suppression effects. On the contrary, Raman spectroscopy is recognized as a non‐destructive analysis method and spectral images can also be acquired. The combination of these two techniques was applied for lipids detection in tissue sections. In MALDI, two lipids families (glycerophosphocholine, PC; gycerophosphoethanolamine, PE), three MALDI matrices (1,5‐diaminonapthalene, 1,5‐DAN; 2,5‐dihydroxybenzoic acid, 2,5‐DHB; a‐4‐hydroxicinammic acid, CHCA), and various mixtures of lipids were investigated. The nature of the lipid, as well as the nature of the matrix and the composition of the sample influences the signal of a given lipid. In Raman, despite a strong overlap with the spectrum of the native tissue, an intensity profile constructed along the diameter of the section clearly shows that the signature of one given lipid (a glycerophosphocholine) can be detected on a doped biological sample.

Allyl sulfides, ajoenes and vinyldithiins are the three main groups of volatile organosulfur compounds that are formed when garlic is crushed. The manner garlic is processed (nature of the extraction medium, temperature…) has a major influence on their relative proportion and the amounts produced. It has been proven recently that the vinyldithiins are at the origin of garlic’s capacity to prevent adipocytes development. Their incorporation in garlic-based nutraceuticals is thus particularly interesting. In this context, this work aims to optimize the production of vinyldithiins from garlic. After having determined the best garlic origin (Spanish) and the best oil for the extraction (olive or sunflower oil), the extraction conditions were optimized (1/2 (w/w garlic oil), 37 °C, 6 h) and 133 mg of vinyldithiins was obtained from 100 g of fresh garlic. Carrying out the extraction under microwave irradiation allowed increasing the yield 3.6-fold (yield 486 mg of vinyldithiins from 100 g of fresh garlic). This study may also contribute to the development of new garlic derived high value products by enhancing the comprehension of their formation. [less ▲]

The relationship between the concentration of plasma progesterone (P4) during embryo attachment or at recognition of pregnancy, and that of pregnancy-associated glycoprotein (PAG) was assessed in dairy cows. The outcome of artificial insemination (AI) was classified as positive (AI+), negative (AIÿ), or late embryonic mortality (EM) by measuring circulating PAG concentrations and by ultrasonography. Based on P4 concentrations at either day 21 or day 15, AI+ and EM cows were classified into ‘low’ (P4 concentrations < mean) and ‘high’ (P4 concentrations > mean) P4 groups. In both experiments, the threshold of P4 concentration between the ‘low’ and ‘high’ groups was approximately 6 ng/mL. PAG concentrations were lower in the ‘low’ group only when P4 concentrations were below the threshold. The study findings suggest that a possible P4 threshold exists below which PAG secretion may be impaired [less ▲]

We used the data from a recently performed genome-wide association study using the Illumina Equine SNP50 beadchip for the detection of copy number variants (CNVs) and examined their association with recurrent laryngeal neuropathy (RLN), an important equine upper airway disease compromising performance. A total of 2797 CNVs were detected for 477 horses, covering 229 kb and seven SNPs on average. Overlapping CNVs were merged to define 478 CNV regions (CNVRs). CNVRs, particularly deletions, were shown to be significantly depleted in genes. Fifty-two of the 67 common CNVRs (frequency ! 1%) were validated by association mapping, Mendelian inheritance, and/or Mendelian inconsistencies. None of the 67 common CNVRs were significantly associated with RLN when accounting for multiple testing. However, a duplication on chromosome 10 was detected in 10 cases (representing three breeds) and two unphenotyped parents but in none of the controls. The duplication was embedded in an 8-Mb haplotype shared across breeds. [less ▲]

Selection for new favorable variants can lead to selective sweeps. However, such sweeps might be rare in the evolution of different species for which polygenic adaptation or selection on standing variation might be more common. Still, strong selective sweeps have been described in domestic species such as chicken lines or dog breeds. The goal of our study was to use a panel of individuals from 12 different cattle breeds genotyped at high density (800K SNPs) to perform a whole-genome scan for selective sweeps defined as unexpectedly long stretches of reduced heterozygosity. To that end, we developed a hidden Markov model in which one of the hidden states corresponds to regions of reduced heterozygosity. Some unexpectedly long regions were identified. Among those, six contained genes known to affect traits with simple genetic architecture such as coat color or horn development. However, there was little evidence for sweeps associated with genes underlying production traits. [less ▲]

BACKGROUND: Whether dark skin produces less vitamin D after UVB radiation than fair skin remains controversial. OBJECTIVE: To compare 25-hydroxyvitamin D [25-(OH)-D] levels after a single UVB exposure in fair (phototype II-III) and black-skinned (phototype VI) volunteers. METHODS: Fair-skinned volunteers (n = 20, 4 males/16 females, mean age: 23.2 years) and black-skinned (n = 11, 6 males/5 females, mean age: 23.8 years) received a single total body UVB exposure (0.022 J/cm(2)). The 25-(OH)-D levels were measured on days 0, 2 and 6. RESULTS: On day 0, all volunteers were severely vitamin D deficient. On day 2, 25-(OH)-D levels of fair-skinned volunteers increased significantly (median: 11.9-13.3 ng/ml, p < 0.0001), but not in black-skinned people (median: 8.60-8.55 ng/ml, p = 0.843). Again, on day 6, 25-(OH)-D levels of fair-skinned volunteers increased significantly (median: 11.9-14.3 ng/ml, p < 0.0001), but not in black-skinned people (median: 8.60-9.57 ng/ml, p = 0.375). CONCLUSION: This study suggests that skin pigmentation negatively influences vitamin D synthesis. [less ▲]

Diabrotica virgifera virgifera Le Conte is considered one of the most important pests of corn grown in monoculture. Damage caused by the Western Corn Rootworm is considerable. The attack is produced by larvae and adults, serious affecting the grain production. Following laboratory analyzes may notice a decrease in the values of all track quality indicators for ears harvested from plants attacked by Diabrotica virgifera virgifera compared with the cobs from the healthy plants. Values of fat content of attacked cobs ranged from 2.76 and 4.23%, protein content ranged from 9.1 to 10.6% and starch between 69.7 and 70.5%. The average fat content of the cobs attacked percentage decreased by 11%, protein content by 16% and starch content dropped by less than one percent. [less ▲]

Mettre en évidence la relation entre occupation humaine et distribution de la végétation est l’un des points abordés par CoForChange. Les récentes études montrent que les perturbations anthropiques ont eu une influence sur la végétation, permettant notamment l’expansion des espèces héliophiles (cf. Lettre n° 4). Pour contribuer à cette analyse dans un contexte de grande rareté des données anthracologiques en Afrique, nous avons, dans le cadre d’un master, choisi d’étudier les charbons de bois issus de neuf fosses pédologiques du projet CoForChange. L’objectif était d’appréhender les compositions floristiques actuelle et passée des forêts au regard des perturbations passées. Deux protocoles anthracologiques d’identification ont été testés : a) à l’échelle de l’espèce, par une description des caractères anatomiques des charbons de bois, une recherche sur la base de données en ligne InsideWood et une comparaison anatomique au Xylarium de Tervuren ; b) à l’échelle de la communauté, par une recherche des relations statistiques entre traits écologiques des espèces et anatomie du bois. Les résultats montrent que la diversité taxonomique sous les forêts à Marantaceae est plus grande que sous les forêts denses de terre ferme. Trois identifications ont été obtenues sur 48 taxons décrits : Gilbertiodendron dewevrei sous forêt monodominante à G. dewevrei (GIB1 à 40 cm de profondeur, 1 510 ± 30 années cal. BP (calibrated before present), Millettia drastica et Pterocarpus soyauxii sous forêt clairsemée à Marantaceae (F9 à 40 cm, 1 200 ± 30 cal. BP). Notre hypothèse est que les peuplements monodominants à G. dewevrei sont relativement stables. Quant à P. soyauxii, la proportion de cette espèce héliophile semble décroître au cours du temps (niveaux entre 20 et 40 cm) au profit desMarantaceae. Un autre résultat porte sur l’absence de Triplochiton scleroxylon sous T. scleroxylon, ce qui pourrait confirmer l’hypothèse du caractère récent de ces peuplements. Les résultats portant sur la relation entre anatomie du bois et traits fonctionnels restant préliminaires, cette recherche sera poursuivie en thèse de doctorat. Les développements actuels de l’anthracologie pour l’Afrique tropicale permettent désormais d’envisager un plus grand nombre d’identifications par échantillon et ainsi une meilleure connaissance de l’évolution des forêts tropicales.

One of CoForChange aims is to highlight the relationship between human settlement and plant distribution. Recent studies show that anthropogenic disturbances have had an impact on vegetation, including enabling the expansion of light-demanding species (see Newsl. No 4). To contribute to this analysis in a context of deep scarcity of anthracological data in Africa, we have been studying the charcoals from nine soil pits of the CoForChange project as part of a Master’s. The objective was to understand past and present species composition of the forests in relation with past disturbances. Two anthracological protocols of identification were tested: 1) at species level, by describing the anatomical characteristics of charcoals, by carrying investigations with InsideWood online database, and by comparing anatomical data at XylariumTervuren; 2) at community level, by searching for statistical relationships between ecological traits of species and wood anatomy. The results show that the taxonomic diversity is greater in Marantaceae forests than in lowland forests. Three identifications were obtained from 48 described taxa: Gilbertiodendron dewevrei under G. dewevrei monodominant forest (GIB1 at 40 cm depth, 1510 ± 30 years cal. BP), Millettia drastica and Pterocarpus soyauxii inMarantaceae open forests (F9 at 40 cm, 1200 ± 30 cal. BP). Our hypothesis is that monodominant stands of G. dewevrei are relatively stable. With regard to P. soyauxii, the proportion of this lightdemanding species seems to be decreasing over time (at levels from 20 to 40 cm) for the benefit of Marantaceae. Another result highlights the absence of Triplochiton scleroxylon under T. scleroxylon, which may confirm the hypothesis of the recent settlement of this species. Results on the relationship between wood anatomy and functional traits are still preliminary, and further research will be conducted through a PhD programme. The on-going developments of anthracology in tropical Africa will help to identify a larger number of collected samples, and thus to understand better the evolution of tropical forests. [less ▲]

A comprehensive analysis of cattle shotgun sequencing data reveals 36 immunoglobulin heavy chain variable genes. The previously described bovine subgroup IGHV1 contains 10 functional genes with a conserved promoter including the consensus octamer and several other transcription factor binding sites, intact exons and matching cDNA sequences. Subgroups IGHV2 and IGHV3 consist entirely of pseudogenes. Thus, the bovine germline IGHV repertoire is very limited. The IGHV genes are distributed in mammalian clans I and II, while no clan III genes were detected. Clan-specific PCR of genomic DNA from cattle, sheep, Eurasian elk, white-tailed deer, pig and dolphin indicates highly dynamic evolution of IGHV gene usage within Cetartiodactyla. The bovine germline IGHV repertoire was probably generated by recent duplications of an IGHV1-IGHV2 homology unit. Immunoglobulin heavy chain genes are largely incorrectly assembled in the current cattle genome versions Btau_4.2 and UMD_3.1. FISH experiments confirm an IGHV locus close to terminus of BTA21.

Five years after the signing of the Paris Declaration on aid effectiveness by donors and developing countries, there is a climate of high expectations about the results achieved and the impact at sector level. Several evaluations and monitoring surveys have been conducted by the OECD to measure progress made so far in implementing the principles of ownership, alignment, harmonisation, results and mutual accountability. For the health sector, results have also been documented in the context of the International Health Partnership (IHP+). We critically reviewed all the aid effectiveness surveys and evaluations published since 2005 by the OECD and IHP+ so as to analyse what results have been achieved so far as well as the relevance of the frameworks used. To date, results of the implementation of the Paris Declaration are mixed. In the health sector, good progress has been achieved in terms of country ownership and coordination, while alignment and use of country systems, managing for results and mutual accountability lag behind. However, the results recorded often reflect different interpretation of the indicators depending on the respondent, the data available or the time of the survey. Making generalisations is therefore difficult and comparisons between country surveys and over time may not be appropriate. Linking progress in aid effectiveness with improvements in health outcomes is also controversial. Results from the evaluations of the Paris Declaration should be used with caution in the current debate about aid effectiveness. What do the indicators used actually tell us? How realistically can aggregated scores reflect complex issues such as aid effectiveness in different countries, by different donors and over time? Improved evaluation is clearly needed. Data collection should be more rigorous and at sector level contextual factors and behaviour change should be better assessed, over a longer term and through more qualitative comprehensive methods.

E. Jehin, J. Manfroid, D. Hutsemekers, M. Gillon, and P. Magain, Fonds National de la Recherche Scientifique, Liege University, report on broad- and narrow-band imaging of the (596) Scheila outburst (CBET 2583) with the TRAPPIST 0.60-m telescope at La Silla, and on optical spectroscopy with the European Southern Observatory's Very Large Telescope (VLT) at Paranal. R-band imaging from 2010 Dec. 12.3 to 21.3 UT revealed two arc-like coma features expanding at a regular pace. The first such feature was 1' long on 2010 Dec. 12, oriented to the northeast and bending to p.a. 280 deg (the anti-solar direction). The second feature was shorter, 30" on Dec. 12, oriented to the south and bending to p.a. 230 deg. Both features were getting larger and fainter with time (4' and 2' long, respectively, on Dec. 21.3). A narrow 45"-long tail, opposite the sun (p.a. 280 deg), was also observed in good seeing. R-band images taken on 2011 Jan. 4.3 and 5.3 after the full moon allowed Jehin et al. to again observe these features, seen as 7' and 4' long, respectively -- and much fainter. This discards any sustained activity of the minor planet. Narrow-band images obtained on 2010 Dec. 12.3 with cometary filters do not show any contribution from gases. A 20-min optical spectrum was obtained with FORS2 at the VLT on Dec. 13.3; it does not show any extended cometary gaseous emissions, but only a spatially extended continuum due to dust-scattered sunlight. Short B, V, R, and I exposures performed nearly every two nights from 2010 Dec. 12.3 to 2011 Jan. 5.3 give a magnitude for the nuclear condensation of V = 14.2 +/- 0.1 over the whole period, in agreement with the "APmag" value reported in the Jet Propulsion Laboratory ephemeris. No flux variation of the nuclear condensation was observed. Those preliminary results are in favor of a collisional scenario to explain the outburst of (596) Scheila, rather than a cometary driven activity. This case might be similar to the outburst of comet P/2010 A2, which may have resulted from an impact of a minor planet (Snodgrass 2010, Nature 467, 814). [less ▲]

In the last decades scholars have acknowledged a major importance to the study of Hellenistic poetry in its context. Therefore, cultural embeddedness has replaced learned isolation as a leading keyword in hermeneutics. Papers presented at the conference "Mythe et pouvoir à l’époque hellénistique" provide an insight into the contribution of poetic texts to the study of Hellenistic political, cultural, and religious history as well as into some methodological issues related to the interpretation of Hellenistic poetry in context. My discussion encompasses the role of myths in shaping identity, legitimating power, and corroborating geopolitical claims, as well as the close interaction between social environment and the updating of stories and genres of the Greek narrative tradition.

The present study was undertaken to evaluate the accuracy of transrectal palpation (TRP) for diagnosing early pregnancy in buffaloes and the false diagnoses of the TRP test by using the pregnancy-associated glycoprotein radioimmunoassay (PAG-RIA) test. Pregnancy was diagnosed in 168 buffalo-cows once by TRP and PAG-RIA test between days 31 and 55 after breeding. The sensitivity of TRP for detecting pregnant buffalo-cows was 37.5% at days 31-35, increased to 93.8% at days 46-50 and reached 100% at days 51-55 (P < 0.01). All cases of false negative diagnoses (n = 10) had PAG concentration higher than the threshold (>/=1.8 ng/mL) for diagnosing pregnancy. The specificity of TRP for detecting non-pregnant buffalo cows ranged between 90.9%, and 100% between days 31 and 55. All cases of false positive diagnoses (n = 5) made by TRP had PAG concentrations lower than the threshold for diagnosing pregnancy. It could be concluded that TRP is an accurate method for diagnosing pregnant and non-pregnant buffalo cows from day 46 after breeding. [less ▲]

Vascular renal resistance (RR) during hypothermic machine perfusion (HMP) is frequently used in kidney graft quality assessment. However, the association between RR and outcome has never been prospectively validated. Prospectively collected RR values of 302 machine-perfused deceased donor kidneys of all types (standard and extended criteria donor kidneys and kidneys donated after cardiac death), transplanted without prior knowledge of these RR values, were studied. In this cohort, we determined the association between RR and delayed graft function (DGF) and 1-year graft survival. The RR (mmHg/mL/min) at the end of HMP was an independent risk factor for DGF (odds ratio 21.12 [1.03–435.0]; p = 0.048) but the predictive value of RR was low, reflected by a c-statistic of the receiver operator characteristic curve of 0.58. The RR was also found to be an independent risk factor for 1-year graft failure (hazard ratio 12.33 [1.11–136.85]; p = 0.004). Determinants of transplant outcome are multifactorial in nature and this study identifies RR as an additional parameter to take into account when evaluating graft quality and estimating the likelihood of successful outcome. However, RR as a stand-alone quality assessment tool cannot be used to predict outcome with sufficient precision. [less ▲]

Because the planets of a system form in a flattened disk, they are expected to share similar orbital inclinations at the end of their formation. The high-precision photometric monitoring of stars known to host a transiting planet could thus reveal the transits of one or more other planets. We investigate here the potential of this approach for the M dwarf GJ 1214 that hosts a transiting super-Earth. For this system, we infer the transit probabilities as a function of orbital periods. Using Monte-Carlo simulations we address both the cases for fully coplanar and for non-coplanar orbits, with three different choices of inclinations distribution for the non-coplanar case. GJ 1214 reveals to be a very promising target for the considered approach. Because of its small size, a ground-based photometric monitoring of this star could detect the transit of a habitable planet as small as the Earth, while a space-based monitoring could detect any transiting habitable planet down to the size of Mars. The mass measurement of such a small planet would be out of reach for current facilities, but we emphasize that a planet mass would not be needed to confirm the planetary nature of the transiting object. Furthermore, the radius measurement combined with theoretical arguments would help us to constrain the structure of the planet [less ▲]

An experiment was carried out to investigate the effect of supplementing lactating cows with cottonseed meal and Vitellaria paradoxa leaves in the rainy season on milk yield and content, cows daily weight gain and profitability. The experimental design was 3 × 3 Latin square with 5 repetitions. Fifteen Borgou cows were offered three diets: grazing on natural pasture, grazing on pasture plus 1.5 kg of cottonseed meal supplement and grazing on natural pasture plus 500 g of Vitellaria paradoxa leaves. Daily milk yield was 946.58 g, 1690.07 g and 1176.89 g for the control, cottonseed meal and Vitellaria paradoxa leaves group respectively. Cows supplemented with cottonseed meal produce significantly (p < 0.05) more milk than the others. The mean values were 15.12%, 0.35%, 5.92% and 4.13% respectively for total solid, ash, fat and protein content. Vitellaria paradoxa leaves significantly (p < 0.05) increase total solid level and ash as well as ash with cottonseed meal. Furthermore, calves daily weight gain (DWG) was significantly different. A net return analysis shows that cottonseed meal and Vitellaria paradoxa leaves supplementation in rainy season was profitable even if Vitellaria paradoxa leaves were more beneficial. [less ▲]

E. Jehin, J. Manfroid, M. Gillon, D. Hutsemekers, and P. Magain report that they observed an occultation of a star of magnitude I about 15.2 by the dwarf planet Eris (then at V about 18.7) on Nov. 6 using the new telescope TRAPPIST at the European Southern Observatory (La Silla). A series of 3-s exposures of a field of size 3' x 3' (1".3/pixel) were secured in fast-readout mode (with a deadtime of 1.5 s), starting at 01h50m UT for one hour. Seven frames centered at 02h19m34s UT allowed them to derive the start of the occultation as 02h19m16s.75 +/- 0s.75 and the end as 02h19m47s.6 +/- 0s.2, for a total occultation time of 30.4 +/- 1.0 seconds. The predictions (see above) made by the Rio de Janeiro group (Assafin et al., Nov. 5) and by J. L. Ortiz estimated the time of the occultation around 02h18m UT for Chile, in good agreement with the observations. During the occultation, a point source is detected with a magnitude corresponding to that of Eris. A small flux increase was also seen at the middle of the occultation, which might result from refraction in Eris' atmosphere (Elliot and Olkin 1996, Ann. Rev. Earth Planet. Sci. 24, 89). Eris is by far the most-remote solar-system object observed to date via stellar occultation, with a geocentric distance of about 96 AU. TRAPPIST is a project driven by the University of Liege, in close collaboration with the Observatory of Geneva, supported by the Belgian Fund for Scientific Research and the Swiss National Science Foundation.
