The sterols of three Reference Materials: a vegetable oil (RM162: a mixture of Soya oil and Maize oil) and two animal fats (RM163: a blend of Pig and Beef fats and RM164: Milkfat) were identified by GC-MS in two experienced laboratories. The techniques used were practically the same nevertheless, Lab. 1 and 2 used respectively an HPLC and a classical TLC method to isolate the sterols from the unsaponifiable matter. Many minor components were detectable when the high efficient HPLC fractionation technique was used but the only molecules similarly identified by the two Labs were considered for the certification of sterol identities. In this article, we present the results of the certification study together with the interpretation of mass spectra. [less ▲]

Les Systèmes de garantie participatifs (SGP) ou certification participa- tive, opposent à ce mécanisme de contrôle par une Tierce Partie Indépendante (TPI), une double critique : celle de la délégation à une partie extérieure et celle de la réduction de la qualité à la normalisation d’un produit. Cette contestation est aujourd’hui reconnue à travers l’institutionnalisation de la certification participative dans la loi de nombreux pays d’Amérique latine. Elle traduit le refus de la marchandisation de la qualité et de la désappropriation des paysans et consommateurs face à la toute-puissance des organismes certificateurs. Pour analyser la critique qu’adressent les SGP au certification TPI et la proposition de certification participative qui en résulte, nous allons nous appuyer sur un cas du sud brésilien : le réseau Ecovida. Ce réseau, pionnier au sud du Brésil, fait partie aujourd’hui d’un mou- vement beaucoup plus vaste allant de l’Inde à l’Amérique latine ; il s’étend dans les pays du Sud et cherche sa voie dans le sud de l’Europe. Il interroge aujourd’hui certains acteurs en Belgique tels que les Groupes d’achat soli- daires de l’agriculture paysanne (GASAP). Cette proposition est une alter- native « agroécologique » dans la mesure où elle est une tentative conjointe des producteurs et des consommateurs de se réapproprier une définition de la qualité qui s’appuie sur d’autres processus que la marchandisation des produits. De plus, elle cherche à intégrer des éléments novateurs chers à l’agroécologie tels que l’emploi paysan, la souveraineté alimentaire et la prise en compte de la biodiversité. [less ▲]

La lutte contre le réchauffement climatique est l’un des principaux enjeux du 21ème siècle. Ce défi est à la source de diverses normes environnementales aux niveaux international, européen, national voire régional. Plusieurs de ces législations visent spécifiquement les entreprises. La directive 2003/87/Ce est l’une des pierres angulaires de ce dispositif normatif. Elle a, en effet, institué le Système d’échange de quotas d’émission de gaz à effet de serre dans l’union européenne, plus connu sous l’expression de «Marché européen des quotas de CO2». Cette directive mais aussi le Protocole de Kyoto engendrent inquiétudes et interrogations dans le chef des entreprises. L’objectif du présent ouvrage est de mettre en lumière la portée et l’impact de ces règles pour les entreprises. Pour ce faire, les auteurs - qu’ils soient praticiens ou issus des milieux académiques - pointent les contraintes pesant sur les entreprises mais également les opportunités que ces législations peuvent générer. L’accent est mis sur les questions posées par le régime juridique des quotas : titrisation, contrat, propriété, aspects fiscaux et comptables, rôle des pouvoirs publics, etc [less ▲]

The preparation of certified rapeseed reference materials and the steps taken to establish the certified values for total glucosinolate contents are described. Details are given of the studies to demonstrate the homogeneity and stability of the material. The results of the certification exercise for total glucosinolate content, which involved European laboratories who applied a variety of methods (high-pressure liquid chromatography, gas liquid chromatography, determination of enzymatically released glucose and sulphate), are presented and discussed. The certified values for the glucosinolate content (mumol/g of non-defatted whole seeds) and the 95% confidence level are the following: CRM 366 (12.1 +/- 0.8 mumol/g), CRM 190 (25.5 +/- 0.9 mumol/g) and CRM 367 (102.4 +/- 3 mumol/g) (CRM = certified reference material). Indicative values (not certified) for individual glucosinolates are also given. Certified sulphur values (mg/g of non defatted whole seeds) have been determined by other laboratories: CRM 366 (3.41 +/- 0.12 mg/g), CRM 190 (4.93 +/- 0.15 mg/g) and CRM 367 (10.5 +/- 0.40 mg/g).

We address the issue of asserting the accuracy of coordinates advertised by nodes of Internet coordinate systems during distance estimations. Indeed, some nodes may lie deliberately about their coordinates to mount various attacks against applications and overlays. Our proposed method consists in two steps: 1) establish the correctness of a node’s claimed coordinate (which leverages our previous work on securing the coordinates embedding phase using a Surveyor infrastructure); and 2) issue a time limited validity certificate for each verified coordinate. Validity periods are computed based on an analysis of coordinate inter-shift times observed on PlanetLab, and shown to follow a long-tail distribution (lognormal distribution in most cases, or Weibull distribution otherwise). The effectiveness of the coordinate certification method is validated by measuring the impact of a variety of attacks on distance estimates. [less ▲]

Schizophrenia is associated with an increased risk of metabolic disorders such as diabetes, dyslipidaemia and the metabolic syndrome. The prevalence of type 2 diabetes in schizophrenic patients is at least twice that of the general population. Around 40 percent of patients meet criteria for the metabolic syndrome. Recently there is a growing concern on the metabolic side effects of treatment with second generation antipsychotics. According to various studies, including a prospective study performed in Flanders, treatment with clozapine and olanzapine has the highest metabolic risk, followed by quetiapine and risperidone. Amisulpride, ziprasidone and aripiprazole appear to have a low metabolic risk. Appropriate care, taking into account the possible improvement of the metabolic risks factors, is important to reduce morbidity and mortality in schizophrenic patients treated with antipsychotic medications.

Glucose is almost the only energy substrate for the brain. Such glucose dependence explains why any large variation of plasma glucose levels could lead to cerebral dysfunction, which may be severe and progress to a coma. Hypoglycaemic coma, the most common one, has a pure metabolic origin (neuroglucopenia) whereas hyperglycaemic coma is more complex and mainly due to osmotic disturbances. Besides acute changes of plasma glucose concentrations, it is generally recognized that more subtle chronic or recurrent glucose abnormalities could also result in brain dysfunction. However, such clinical consequences are more difficult to assess in clinical practice. Nevertheless, learning perturbations in young patients with type 1 diabetes and memory losses, sometimes severe and subject to progress to dementia ("diabetic encephalopathy") in older type 1 or type 2 diabetic patients, have been reported, although with some controversy. The present paper summarizes the current knowledge of both acute and chronic cerebral dysfunctions following perturbations of blood glucose levels in diabetic patients. [less ▲]
