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 ▲]

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.

A field test and a standardized treadmill test were used to assess fitness in endurance horses. These tests discriminated horses of different race levels: horses participating in races of 120km and more showed higher values of VLA4 (velocity at which blood lactate reached 4 mmol/L) and V200 (velocities at which heart rates reached 200 beats per min) than horses of lower race levels.

We initiate this review article by a brief description of a few monogenic autoimmune diseases such as the APECED and the IPEX syndrome because they allow understand the fundamental mechanisms of self tolerance. Next we describe with more details the complex autoimmune diseases and discuss the recent data regarding the associated genetic and environmental factors and their modes of interaction. The conclusion of the article deals with the practical implications of this inherent complexity for the researcher and the clinician. [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.

The evaluation of the Paris declaration on aid effectiveness: what does it tell us? What results for the health sector?

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 ▲]

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 ▲]

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.

During a case control study undertaken in 2006-2007, a screening and consensus polymerase chain reaction (PCR) was performed to evaluate the potential role of equid herpesviruses (EHV) in several occurrences of respiratory disorders in 661 horses. Of 785 bronchoalveolar or tracheal lavage fluid samples submitted for analysis, 20 were positive for EHV-5 DNA by sequential analysis of the consensus PCR product. Nineteen of those samples were confirmed using a specific EHV-5 PCR. No particular changes in cytological profile could be associated with the detection of EHV-5 in contrast to suggestions in previous reports of natural or experimental respiratory viral infections in horses or ponies. This is the first description of EHV-5 isolation in equine respiratory fluids in Europe, but further investigations are needed to determine the potential pathogenic role of this gammaherpesvirus in the horse.
