Predicting no return to sports after three months in patients with traumatic knee complaints in general practice by combining patient characteristics, trauma characteristics and knee complaints.

Conclusion: Three out of four patients with a knee trauma in general practice reported return to sports at three months follow-up. A combination of patient/trauma characteristics and knee complaints predicted no return to sports, whereas MR findings had no additive value.   Trial registration: Dutch trial registration: registration number: NTR3689. registration date: 7 November 2012.

Abstract Derivatization is frequently used in liquid chromatography-mass spectrometry (LC-MS) to improve the ionization characteristics of analytes, and facilitate their structural elucidation and quantification. However, the off-line derivatization process usually requires more analysis time. Therefore, the present work develops a novel LC/post-column derivatization (PCD)/MS (LC-PCD-MS) method for rapid detection of aldehydes in complex samples. The PCD method is based on a bisulfite addition reaction with aldehydes that can be easily conducted by mixing the LC elute with an (NH4)2SO3 solution via a tee. The resu...

Abstract In the present work, an analytical approach for the voltammetric detection and prediction of adulteration of fresh cow milk with reconstituted skim milk powder is developed. After precipitation of milk proteins upon addition of ethanol and centrifugation, the supernatant liquid of the samples was analyzed by cyclic voltammetry on a novel graphite/SiO2 hybrid working electrode (GSiHE) using LiClO4 as electrolyte. Under these conditions, fresh milk samples gave broadened peaks/plateaus in both forward and backward potential scanning, attributed mainly to oxidases. Such peaks were not evident in the case of ...

Abstract Proteinase K (ProK) is used for the degradation of proteins in cell lysates to isolate nucleic acids, and for the speciation of proteins for mass spectrometry analysis. In this work, a novel and sensitive immobilization process was developed for examination of protein mixtures by combining MALDI-ToF-MS and nLC-TIMS-ToF-MS/MS systems. To achieve these goals, magnetic nanoparticles (MPs) were prepared via thermal coprecipitation reaction under alkaline condition. The MPs were grafted with a silica layer (i.e., 3-(2,3-epoxypropoxy) propyltrimethoxysilane; EPTES) containing reactive epoxy groups. Then, the si...

Abstract Organic compounds and vegetable origin oils are subject to scratiny in the photonics and nonlinear optics area, due to their high non-linear response: a characteristic linked to the molecular nature of these compounds and their own chemical bond. In the food industry, quick and non-invasive studies are needed to evaluate the nutritional quality of edible products. The nonlinear optical response of 4 vegetable oils was analyzed: extra virgin olive oil (EVOO), extra virgin sesame oil (EVSO), extra refined linseed oil (ERLO) and virgin avocado oil (VAVO), using the Z-scan technique. Where the third order ele...

In this study, we developed an impedimetric sensor system by using molecularly cortisol imprinted acrylamide polymers on fullerene modified carbon electrode to detect cortisol in real saliva samples. The polymer layer was formed on fullerene modified screen printed carbon electrodes with the ratio of 1:2 (cortisol:acrylamide) and ammonium persulfate (APS) was used as the initiator of polymerization. The sensor surface was investigated by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and Scanning Electron Microscopy (SEM). Performances of the electrode were determined as follows; calibration curve wa...

In this study, effects of natural aging as an interlude on the mechanical properties of artificially aged SiCp/6092Al composite and 6092Al alloy were investigated using tension test, electrical conductivity test, differential scanning calorimetry and transmission electron microscopy. It was shown that the strength of both the composite and 6092Al alloy after artificial aging was decreased due to the precedent natural aging. Compared to 6092Al alloy, the composite had smaller strength decrement. However, qualitative analysis based on load transfer indicated that the negative influence of natural aging was stronger in the co...

FerreiraAbstractRecent studies show that polyaniline (PAni) is one of the widely studied materials because it is easy synthesis, less cost, and low environmental pollution. Moreover, it presents a high theoretical specific capacitance as compared to carbon-based electrodes. Besides, when combined with materials such as porous carbon, graphene, carbon fiber, among others, the resulting electrodes composites present high electrochemical performance with feature commercially viable for practical applic...
