Medicinal diagnosis requires the development of innovative devices allowing the detection of small amounts of biological species. Among the large variety of available biosensors, the ones based on fluorescence phenomenon are really promising. Here, we show a prototype of the basic unit of a multi-sensing biosensor combining optics and microfluidics benefits. This unit makes use of two crossed optical fibers: the first fiber is used to carry small probe molecules droplets and excite fluorescence, while the second one is devoted to target molecules droplets transport and fluorescence detection. Within this scheme, the interaction takes place in each fiber node. The main benefits of this detection setup are the absence of fibers functionalization, the use of microliter volumes of target and probe species, their separation before interaction, and a better detection limit compared to cuvettes setups.

A new approach to monitoring surface waters using distributed fiber optic temperature sensing is presented, allowing resolutions of temperature of 0.01°C every meter along a fiber optic cable of up to 10,000 m in length. We illustrate the potential of this approach by quantifying both stream temperature dynamics and groundwater inflows to the Maisbich a first-order stream in Luxembourg (49°47′N, 6°02′E). The technique provides a very rich dataset, which may be of interest to many types of environmental research, notably that of stream ecosystems. [less ▲]

The potential of fibre concentrate from artichoke stem by-product in bakery application was investigated. The elaboration of fibre concentrate was characterized by an extraction yield of 48.5%. The chemical composition showed high total dietary fibre (85 g/100 g d.m) and low lipid contents (0.5 g/100 g d.m). The fibre concentrate showed good water holding capacity (8.17 g/g) and high oil holding capacity (16.17 g/g). The effect of fibre concentrate incorporation to wheat dough, at level of 2%, on the rheological properties and physical characteristics of bread was also evaluated. The results showed that the addition of fibre concentrate in wheat flour significantly improved (P<0.05) dough properties inducing an increase of water absorption, stability and tenacity, and a reduction of extensibility and softening in comparison to the dough without fibre. The colour values of the crust and crumb were significantly (P<0.05) altered by the addition of fibre concentrate. It was also found that incorporation of fibre concentrate to bread produced a comparable specific volume and enhanced the shelf life, as textural studies revealed. [less ▲]

Cette étude relate les effets de la distribution de deux rations enrichies en pulpes de betterave ou de chicorée (7 p.100 ADF dans la matière sèche) en comparaison à une ration témoin sur les paramètres fécaux, la digestibilité des principaux nutriments et plusieurs paramètres biochimiques (glucose, insuline, azote alpha-aminé, urée, cholestérol et triglycérides) mesurés à jeun ou pendant six heures après le repas chez huit chiens adultes en bonne santé. Les régimes enrichis en pulpes ont entraîné une augmentation significative de l'excrétion fécale totale, de l'excrétion de MS dans les matières fécales, une diminution de la teneur en MS des fèces ainsi qu'une diminution des coefficients de digestibilité des principaux nutriments. Le régime contenant la pulpe de betterave a entraîné une diminution de la glycémie à jeun, de l'insulinémie et des concentrations en triglycérides postprandiales, des concentrations en urée et en cholestérol mesurées avant et après le repas. Le régime contenant la pulpe de chicorée a provoqué une diminution de l'insulinémie postprandiale, des concentrations en urée et en cholestérol à jeun et après le repas. Ces deux types de pulpes, semblables par leur composition, induisent les mêmes types d'effets sur les paramètres fécaux et la digestibilité des nutriments, mais les effets systémiques sont plus importants lors de la distribution de pulpes de betterave.

Dietary fibres can modify the intestinal structure in dogs and other animal species. The main changes concern not only the morphology of the gastrointestinal tract but also the ultrastructures. Furthermore, soluble and partly-soluble fibres are fermented in the large bowel; the fermentation products have different metabolic effects. The physical and chemical properties of fibres can be used for the dietary therapy of some intestinal pathologies [less ▲]

The role of collagens and collagen receptors was investigated in stimulating platelet-dependent thrombin generation. Fibrillar type-I collagens, including collagen from human heart, were most potent in enhancing thrombin generation, in a way dependent on exposure of phosphatidylserine (PS) at the platelet surface. Soluble, non-fibrillar type-I collagen required pre-activation of integrin alpha2beta1 with Mn2+ for enhancement of thrombin generation. With all preparations, blocking of glycoprotein VI (GPVI) with 9O12 antibody abrogated the collagen-enhanced thrombin generation, regardless of the alpha2beta 1 activation state. Blockade of alpha2beta1 alone or antagonism of autocrine thromboxane A2 and ADP were less effective. Blockade of alphaIIbbeta3 with abciximab suppressed thrombin generation in platelet-rich plasma, but this did not abolish the enhancing effect of collagens. The high activity of type-I fibrillar collagens in stimulating GPVI-dependent procoagulant activity was confirmed in whole-blood flow studies, showing that these collagens induced relatively high expression of PS. Together, these results indicate that: i) fibrillar type-I collagen greatly enhances thrombin generation, ii) GPVI-induced platelet activation is principally responsible for the procoagulant activity of fibrillar and non-fibrillar collagens, iii) alpha2beta1 and signaling via autocrine mediators facilitate and amplify this GPVI activity, and iv) alphaIIbbeta3 is not directly involved in the collagen effect.

Cardiovascular mortality of hemodialysis patients remains a major problem. The prevalence and incidence of atrial fibrillation in this population are more important than in the general population. The indication of antivitamin K therapy (AVK) in this context of atrial fibrillation must be weighted against the increased risk of bleeding. Unfortunately, and contrary to the general population, an indication of anticoagulation based on embolic or hemorrhagic risk scores is not as clearly established in the hemodialysis population. No prospective randomized study has investigated the benefit/risk balance of anticoagulant treatment in hemodialysis subjects. This article is a review of the current literature on this topic, showing the prevalence of thromboembolic but also bleeding events in the hemodialysis population. The impact of AVK treatment in this specific population is also reviewed. To the best of our knowledge, the indication of treatment must be individualized. [less ▲]
