Les oligosaccharides pectiques ou POS sont des fragments de composition complexe issus de la dégradation chimique, physique ou enzymatique de la pectine. Du fait de l’intérêt de leurs propriétés biologiques, les oligosaccharides pectiques font l’objet de nombreuses études et trouvent aujourd’hui des applications dans des domaines aussi différents que la médecine, l’agriculture et l’industrie agro-alimentaire. Cet écrit présente la structure des pectines ainsi que les différents modes de production des POS en insistant particulièrement sur les différentes enzymes microbiennes permettant de les obtenir et sur les applications possibles de ces POS.

The ability of the strains Yarrowia lipolytica and Candida rugosa to grow on Olive Mill Wastewater (OMW) based medium and to produce high-value compounds from OMW (such as enzymes), while degrading this waste, was tested. Factors affecting cellular growth and OMW degradation were also studied, such as OMW composition, dilution and supplementation. OMW collected from 3-phase olive mill of the north region of Portugal were used and characterized chemical and biochemically. OMW with COD ranging from 100 g·L-1 to 200 g·L-1 were supplemented with yeast extract and ammonium chloride proportionally to its organic composition. Preliminary studies of OMW consumption were carried out in batch cultures of Y. lipolytica W29 and C. rugosa PYCC 3238. The strains were able to grow in the OMW used without dilution, to consume almost all of the sugars present in the media and to significantly reduce COD. Y. lipolytica W29 was less affected by operating conditions changes such as, stirring rate variation and OMW medium supplementation. [less ▲]

BACKGROUND: Microalbuminuria is an early predictor of diabetic nephropathy and premature cardiovascular disease. We investigated whether treatment with an angiotensin-receptor blocker (ARB) would delay or prevent the occurrence of microalbuminuria in patients with type 2 diabetes and normoalbuminuria. METHODS: In a randomized, double-blind, multicenter, controlled trial, we assigned 4447 patients with type 2 diabetes to receive olmesartan (at a dose of 40 mg once daily) or placebo for a median of 3.2 years. Additional antihypertensive drugs (except angiotensin-converting-enzyme inhibitors or ARBs) were used as needed to lower blood pressure to less than 130/80 mm Hg. The primary outcome was the time to the first onset of microalbuminuria. The times to the onset of renal and cardiovascular events were analyzed as secondary end points. RESULTS: The target blood pressure (<130/80 mm Hg) was achieved in nearly 80% of the patients taking olmesartan and 71% taking placebo; blood pressure measured in the clinic was lower by 3.1/1.9 mm Hg in the olmesartan group than in the placebo group. Microalbuminuria developed in 8.2% of the patients in the olmesartan group (178 of 2160 patients who could be evaluated) and 9.8% in the placebo group (210 of 2139); the time to the onset of microalbuminuria was increased by 23% with olmesartan (hazard ratio for onset of microalbuminuria, 0.77; 95% confidence interval, 0.63 to 0.94; P=0.01). The serum creatinine level doubled in 1% of the patients in each group. Slightly fewer patients in the olmesartan group than in the placebo group had nonfatal cardiovascular events--81 of 2232 patients (3.6%) as compared with 91 of 2215 patients (4.1%) (P=0.37)--but a greater number had fatal cardiovascular events--15 patients (0.7%) as compared with 3 patients (0.1%) (P=0.01), a difference that was attributable in part to a higher rate of death from cardiovascular causes in the olmesartan group than in the placebo group among patients with preexisting coronary heart disease (11 of 564 patients [2.0%] vs. 1 of 540 [0.2%], P=0.02). CONCLUSIONS: Olmesartan was associated with a delayed onset of microalbuminuria, even though blood-pressure control in both groups was excellent according to current standards. The higher rate of fatal cardiovascular events with olmesartan among patients with preexisting coronary heart disease is of concern.

Dopo aver indicato alcuni elementi di convergenza fra Piaget e Skinner, l'autore esamina criticamente il concetto piagetiano di "stadio" alla luce della teoria dell'apprendimento. Vengono esaminate situazioni di seriazione e classificazione. Procedure d'addestramento e d'esme differenti da quelle tradizionali portano a concludere che talune abilità compaiono prima di quanto è ipotizzato da Piaget, mentre altre apparirebbero molto piú tardi o sarebbero lacunose nello stresso adulto.

This article aims to show how the cultural potential of the Olympic stadium can offer new possibilities for its space and its use in relation to the city. The approach considers the UNESCO WCH and the Granada Convention criteria for highlighting three specific aspects of its design: innovation through architecture and technologies; influence on the urban environment; role as a cultural space and as part of a cultural territory. The article helps to better define the cultural heritage significance of those emblematic stadiums. [less ▲]

The article analyses the relationship between Olympic stadiums and the urban environment. This relationship is considered as key to understanding the cultural significance of these exceptional event-based buildings. It helps to explain present challenges faced by their conservation and raises the issue of considering likely heritage values at the design stage of stadiums. [less ▲]

L’asthme est une maladie chronique des voies aériennes. La plupart des asthmatiques ont une inflammation bronchique liée à un processus immunologique faisant intervenir les immunoglobulines E (IgE). En dépit des thérapeutiques existantes, les patients atteints d’asthme sévère ont une qualité de vie sérieusement altérée et présentent un risque élevé d’exacerbations graves pouvant parfois être fatales. L’omalizumab est un anticorps (Ac) monoclonal humanisé dirigé contre les IgE circulantes, interférant ainsi avec une des cascades moléculaires importantes dans la pathogénie de l’asthme. L’omalizumab a montré qu’il était capable d’améliorer la qualité de vie et de réduire la fréquence des exacerbations ainsi que le recours aux corticoïdes inhalés et systémiques. Selon les nouvelles recommandations de l’asthme du GINA 2006, cet agent biologique est indiqué dans l’asthme allergique persistant sévère. [less ▲]

The paper presents the efforts and results of a large consortium of European Industries, Research Centers and Universities involved in an EU research project named OMASES in the field of Power System Dynamic Security Assessment (DSA). The overall structure of an on-line DSA tool including TSA – Transient Stability Assessment, VSA – Voltage Stability Assessment, TS – Training Simulator and MS – Market Simulator is reported. Some basic assumptions and methodological aspects of the tool are presented considering its possible use within actual or future Energy Management Systems under the new electric market environment. Scenarios set up for the validation phase and results are reported with reference to the Italian test facility. [less ▲]

The Optical Monitoring Camera (OMC) will observe the optical emission from the prime targets of the gammaray instruments onboard the ESA mission INTEGRAL, with the support of the JEM-X monitor in the X-ray domain. This capability will provide invaluable diagnostic information on the nature and the physics of the sources over a broad wavelength range. Its main scientific objectives are: ( 1) to monitor the optical emission from the sources observed by the gamma- and X-ray instruments, measuring the time and intensity structure of the optical emission for comparison with variability at high energies, and ( 2) to provide the brightness and position of the optical counterpart of any gamma- or X-ray transient taking place within its field of view. The OMC is based on a refractive optics with an aperture of 50 mm focused onto a large format CCD (1024 x 2048 pixels) working in frame transfer mode (1024 x 1024 pixels imaging area). With a field of view of 5degrees x 5degrees it will be able to monitor sources down to magnitude V = 18. Typical observations will perform a sequence of different integration times, allowing for photometric uncertainties below 0.1 mag for objects with V less than or equal to 16. [less ▲]
