Abstract
SCOPE The consumption of processed meat is associated with increased risk of chronic diseases, but determining how the exposure to specific cooking processes alters the metabolome is an analytical challenge. This study aims to evaluate the impact of four typical cooking methods for beef (boiling, barbecuing, grilling, and roasting) on the urinary metabolite profiles in rats, using a non-targeted approach. METHODS AND RESULTS Male Wistar rats (n = 48) are fed for 3 weeks with experimental diets containing either raw or cooked (boiled, barbecued, grilled, and roasted) beef. A control group is fed with milk proteins. The 24 h-urines are analyzed using LC-MS. The consumption of boiled meat leads to the specific excretion of di- and tri-peptides (aspartyl-leucine, glycyl-aspartate, and aspartyl-prolyl-threonine) and a cyclo-prolyl-proline (p < 0.001). No singular metabolite specifically associated with the groups "grilled," "roasted," and "barbecued" meat is observed. CONCLUSION Urinary metabolite profiles of rats fed boiled beef are clearly distinct from those of rats fed with raw, grilled, roasted, or barbecued beef. The specific metabolites include the products of non-digested proteins and may be useful as potential intake biomarkers of this meat cooking method.

Abstract
Abstract
Objectives
Severely low-protein (LP) diets induce a decrease in body weight and an increase in relative food including intake (FI) in rat. In the liver, changes in anabolic and catabolic protein pathways could transitorily participate to compensate for amino acid (AA) deficiency. The present study investigated these liver and muscle protein metabolic pathways on LP diet fed growing rats.
Methods
Growing rats were fed for three weeks different diets containing 3–5–8–12–15 or 20% energy from milk protein. Body weight and FI were measured daily. At the end of the experiment, rats were injected with 13C valine and tissues and biological fluids were collected for gene expression measurement, blood AA UPLC analysis and protein
synthesis rate determination in liver and muscle. Statistical analysis was done by 1- or 2-factor ANOVA, when data were repeated.
Results
P3, P5 and P8% diets resulted in significant growth retardation and significant decrease in lean mass. Severe protein deficiency induced a decrease in the rate of protein synthesis in the liver and muscle. In addition, the results showed activation of the GCN2 pathway, via ATF4-CHOP-TRB3 both in the liver and in the muscle, which suggests the inhibition of the initiation of translation at the level of the binding of the RNAt-Met. Liver proteolytic pathways were up-regulated including the ubiquitin-proteasome, the caspase system and the autophagy. In muscle, both the ubiquitin-proteasome pathway, and autophagy were increased as well as the calpain system. The GCN2 pathway, via ATF4-CHOP-TRB3 was activated in both liver and muscle, confirming the activation of protein degradation by the ubiquitin-proteasome pathways, and autophagy. In portal vein, indispensable AA were lower in severe protein deficient diet whereas in vena cava no difference was observed.
Conclusions
Severe protein restriction lowered protein synthesis and activated protein catabolism in both liver and muscle whereas no effect was observed for moderate protein restriction. These results confirm that the liver and muscle play a major role in supplying the body with indispensable AA in response to severe protein restriction.

Abstract
Abstract
Objectives
The availability of indispensable amino acids (IAA) modulates protein turnover. More particularly AAI deficiency reduces protein synthesis while the consequence on proteolysis remains unclear. The present study aims to evaluate the specific response of both protein synthesis and proteolysis to a diet restricted on one strictly indispensable IAA, either lysine or threonine
Methods
Sixty-four growing rats were divided into 8 groups (n = 8/group). They were fed for 3 weeks isocaloric diets composed with different levels of lysine or threonine (L or T), 15, 25, 40, 60, 75, 100 or 170% of the theoretical lysine/threonine requirements. At the end of the experiment, rats were injected with valine13C and tissues and biological fluids were collected for gene expression measurement
and blood amino acids (AA). Protein synthesis rate (Fractional and Absolute rate synthesis, ie FSR, ASR) were determined in liver and muscle. Statistical analysis was done by 1- or 2-factor ANOVA, when data were repeated.
Results
Severe (L/T15, L/T25) and moderate (T40) lysine or threonine deficiency resulted in a decrease in body weight gain due to a decrease in lean body mass. Severe restriction (L15, T15, T25) decreased the muscle FSR whereas no effect was observed in the liver. When the rate of protein synthesis was expressed per tissue, the ASR was decreased by severe restriction of lysine and threonine in liver and muscle and by moderate threonine deficiency (T40, T60, T75) in muscle. In liver, no effect of lysine and threonine on proteolysis was observed. In muscle, only severe lysine (L15) deficiency increased proteolysis. Dietary lysine deficiency induced a decrease in lysine concentration in the portal vein and in the vena cava whereas for threonine deficiency, all AAIs except threonine were decreased in the portal vein and vena cava.
Conclusions
These results indicate that the decreased protein synthesis is the primary mechanism involved in decreased lean body mass in response to the severe deficiency in a single AAI. Deficiency of a single AAI reproduce the effect of the low protein diet on protein synthesis. Lysine and threonine deficiency differently affect for a part protein turnover probably in relation with the tissue where they are metabolized.

Abstract
Wine composition in polyphenols is related to the variety of grape that it contains. These polyphenols play an essential role in its quality as well as a possible protective effect on human health. Their conjugated aromatic structure renders them fluorescent, which means that 3D front-face fluorescence spectroscopy could be a useful tool to differentiate among the grape varieties that characterize each wine. However, fluorescence spectra acquired simply at the natural pH of wine are not always sufficient to discriminate the wines. The structural changes in the polyphenols resulting from modifications in the pH induce significant changes in their fluorescence spectra, making it possible to more clearly separate different wines. 9 wines belonging to three different grape varieties (Shiraz, Cabernet Sauvignon and Pinot Noir) and from 9 different producers, were analyzed over a range of pHs. Independent Components Analysis (ICA) was used to extract characteristic signals from the matrix of unfolded 3D front-face fluorescence spectra and showed that the introduction of pH as an additional parameter in the study of wine fluorescence improved the discrimination of wines.

Abstract
Selective elimination of residual error can be used when applying Harrington's ANOVA-PCA in order to improve the capabilities of the method. ANOVA-PCA is sometimes unable to discriminate between levels of a factor when sources of high residual variability are present. In some cases this variability is not random, possesses some structure and is large enough to be responsible for the first principal components calculated by the PCA step in the ANOVA-PCA. This fact sometimes makes it impossible for the interesting variance to be in the first two PCA components. By using the proposed selective residuals elimination procedure, one may improve the ability of the method to detect significant factors as well as have an understanding of the different kinds of residual variance present in the data. Two datasets are used to show how the method is used in order to iteratively detect variance associated with the factors even when it is not initially visible. A permutation method is used to confirm that the observed significance of the factors was not accidental.

Abstract
Foods are complex mixtures of macro- and micronutrients, which interact, leading to oxidation, glycation, and hydrolysis upon heating (e.g., sterilization, cooking) and storage. Their nutritional quality and safety are consequently affected, justifying the need for accurate monitoring of the evolution of the food composition during processing and shelf life. Classical chromatographic analysis as well as newly proposed rapid methods based on fluorescence spectrometry analyses were applied on whey powder-based models and commercial samples (in powdered form and ultrahigh temperature [UHT] sterilized), some of which had been previously submitted to protein hydrolysis. These samples were incubated for 48 h at 60 degrees C to mimic accelerated storage. Fluorescence fingerprints addressing modifications in the product composition during processing were recorded and analyzed by chemometric methods. Carboxymethyllysine (Nepsilon-[carboxymethyl]lysine; CML) was measured using an ELISA method. Fluorescence, recorded in a front-face mode on intact samples, is very sensitive to pertinent physicochemical changes induced by heat treatment, formulation (the moisture level in powders, presence of vitamin C and iron), and storage. Similar trends were observed between powders' fluorescence and CML-for example, a strong effect of protein hydrolysis and increasing water content. Addition of vitamin C was associated with an antioxidant effect despite the presence of iron. Good calibration models were obtained for predicting CML from fluorescence spectra both in food models and in commercial samples, although more work is needed to obtain accurate and robust calibration models. Results show the potential of nondestructively applied fluorescence spectrometry for measuring CML in formulas, a rapid, simple, and cost-effective method to monitor formula quality.
