Summary: The aim of this present research was to study the antifungal properties of lactic acid bacteria (LAB) isolated from fermented Mill flour and fermented cassava in order to use them for biopreservation. Antifungal activity of these LAB were assessed in MRS solid medium against food spoilage moulds as Aspergillus niger MUCL 28699, Aspergillus niger CWBIF194, Aspergillus tubingensis MP1 and Penicillium crustosum MY1. Three strains, Lactobacillus plantarum VE56, Weissella cibaria FMF4B16 and Weissella paramesenteroides LC11 were selected among 116 for their strongest inhibitory activity and their broad inhibitory spectrum against food moulds. The 4-fold concentrated supernatant of L. plantarum VE56 and W. paramesenteroides LC11 had the strongest inhibitory activity to compare to W. cibaria FMF4B16. The antifungal activity of the cell-free supernatant was pH dependent and insensitive to proteolytic enzymes action suggesting that the inhibitory activity was due to other compounds than proteins. The identification of antifungal compounds by chromatographic studies highlighted the production of phenyllactic acid by the three strains. In addition, 2-hydroxy-3-methylpentanoic acid and 2-hydroxy-4-methylpentanoic acid were produced by L. plantarum VE56 and W. paramesenteroides LC11. However, the concentration assessed in the supernatant was lower than the minimal inhibitory concentration showing a synergic action of all these produced compounds. The effect of the antifungal supernatant of L. plantarum VE56 and W. paramesenteroides LC11 on Aspergillus flavus NRRL 3357 resulted to an inhibition of conidial development and aflatoxin B1 production which was reflected in decreased gene expression of brlA (conidiophore specific transcription factor) and laeA (global regulator of secondary metabolism). These two bacteria also delayed Penicillium expansum MUCL 14498 conidial development in bread. [less ▲]

Vietnam locates in the Asia-the most active region, where gains the highest economic growth rate and highest milk consumption in the world. Vietnam also ranks the second among the highest milk productivity in the Asia and milk consumption is increasing rapidly. However, the dairy industry in Vietnam is currently able to meet only 22% of domestic demand; the remaining amount has been imported (VOV/VNA, 2008). In addition, raw milk price is very low while retail price is too high. It leads to low effective in the production of the whole chain. This paper is based on the value chain approach within both quantitative and qualitative methods to evaluate a typical fresh value chain in the North of Vietnam in (Moc Chau platation) in 2008 - 2010. The findings show that the dairy plant is the most powerful actor in the chain and it drives the whole chain while power of dairymen is very weak. The value added of the chain is distributed unequally among its actors in whom more benefitable for non-dairy cow producers. In particular, the value added in dairy cow stage would be much lower.

BACKGROUND AND PURPOSE: The clinical picture of hand atrophy related to a cervical rib or elongated C7 transverse process was well described in the modern literature by Gilliatt and Sumner; in 1970, they reported a series of nine patients whose motor status was stabilized following brachial plexus decompression. We report here seven patients suffering from thoracic outlet syndrome (TOS), who developed hand atrophy, sometimes because of diagnostic delay. METHODS: The patient's charts were analysed retrospectively. RESULTS: The seven patients were all female; the mean age was 43 years. The first complaints were arm pain and paresthesias lasting six months to 5 years. Three patients were treated with C56/C67 discectomy plus disc prosthesis (one patient), ulnar neurolysis at the elbow (the same patient), carpal tunnel release (one patient), and intravenous immunoglobulins (one patient) before TOS diagnosis. Hand atrophy, severe in five patients, was present at presentation. All patients underwent brachial plexus decompression by the anterior (four), posterior (two), or transaxillary (one) approach. This last approach was completed 18 months later by brachial plexus neurolysis via the anterior approach. Postoperatively, motor deficit was improved in two patients and stabilized in five patients. CONCLUSIONS: Physicians' unfamiliarity with TOS diagnosis or their reluctance to accept the diagnosis without electrical confirmation can lead to hand atrophy. Brachial plexus decompression at this stage usually stabilizes the deficit. [less ▲]

During the All Taxa Biodiversity Inventory + Monitoring programme (ATBI+M) in the Mercantour and Alpi Marittime National Parks, our inventories of bryophytes identified 234 taxa (mosses and liverworts). This work completes the previous field campaigns, notably those of Jean-Pierre Hebrard (I MEP, Marseille) since 1965, and the ATBI bryophyte inventories in 2007. This number is based on four days of inventories in the central and peripheric territory of both National Parks, in four days in July and August 2010, together with previous data the 565 taxa known from the area still underestimate the number of species actually present. Our observations in 2010 added several new species for this area, including several rare and remarkable species such as Haplomitrium hookeri or species listed under the Habitats Directive as Buxbaumia viridis and Orthotrichum rogeri. Given the rarity of their habitats species from snow beds, large block boulders and high altitude wetlands are most remarkable. [less ▲]

Nous développons un modèle dans lequel les travailleurs peuvent avoir tendance à trop travailler quand ils sont jeunes, parce qu’ils ne peuvent ou ne veulent pas voir les conséquences que cela peut avoir sur leur santé et sur leur capacité à travailler longtemps. Pour les obliger à mieux répartir leurs efforts sur leur cycle de vie, une taxe sur les revenus du travail en début de vie et une subvention de l’épargne sont souhaitables. Si la subvention de l’épargne n’est pas disponible, la taxe optimale arbitre entre quatre considérations différentes. Nous étudions également la taxe optimale quand les individus diffèrent en productivité. [less ▲]

Regression is a commonly used technique for describing the relationship between a response variable and one or more explanatory variables. When the response variable is a categorical variable, usual regression based on ordinary least squares should be replaced by logistic regression. Binary logistic regression should be used to perform a regression on a dichotomous response. Nominal polytomous logistic regression applies to a categorical response variable that has more than two levels with a natural ordering. And ordinal polytomous logistic regression is used when the response is a categorical variable that has more than two levels with a natural ordering. This note gives an overview of these logistic regression methods and describes three models commonly used when performing ordinal logistic regression. These models are illustrated by an example related to oak decline in the Walloon Region (Belgium). [less ▲]

L'eczéma chronique des mains représente une difficulté thérapeutique majeure en dermatologie, et en particulier, quand l'exploration allergologique ne permet pas d'identifier l'agent responsable de l'affection ou que l'éviction de celui-ci est difficile à obtenir pour raisons professionnelles. La première approche thérapeutique consiste en l'application de dermocorticoïdes. Cependant, leur utilisation chronique n'est pas recommandée en raison de leurs effets secondaires tels que l'atrophie cutanée. L'application topique des inhibiteurs de la calcineurine, comme le tacrolimus ou le pimecrolimus peut être envisagée comme traitement complémentaire. La photothérapie par UVB ou par PUVA est un traitement de deuxième ligne. Le méthotrexate et la ciclosporine sont des médicaments à réserver aux cas graves et multirésistants. L'alitrétinoïne, rétinoïde endogène et agoniste des récepteurs aux rétinoïdes, est une nouvelle thérapeutique contre l'eczéma chronique des mains qui ne répond plus aux dermocorticoïdes et est réfractaire aux autres options thérapeutiques. Plusieurs études randomisées, multicentriques et contrôlées contre placebo ont montré l'efficacité et l'innocuité de l'alitrétinoïne dans l'eczéma chronique des mains résistant aux traitements classiques.
