Plasma leptin turnover rates in lean and obese Zucker rats
Conscious female adult lean and obese Zucker rats were injected through the jugular vein with radioactive iodine-labeled murine leptin; in the ensuing 8 min, four blood samples were sequentially extracted from the carotid ...
Growth-Promoting Effect of Cava Lees on Lactic Acid Bacteria Strains: A Potential Revalorization Strategy of a Winery By-Product
The growing trend of circular economy has prompted the design of novel strategies for the revalorization of food industry by-products. Cava lees, a winery by-product consisting of non-viable cells of Saccharomyces cerevisiae ...
Biochemical and proteomic analyses of the physiological response induced by individual housing in gilts provide new potential stress markers
BACKGROUND: The objective assessment of animal stress and welfare requires proper laboratory biomarkers. In this work, we have analyzed the changes in serum composition in gilts after switching their housing, from pen to ...
Nutritional regulation of gene expression: carbohydrate-, fat- and amino acid-dependent modulation of transcriptional activity
The ability to detect changes in nutrient levels and generate an adequate response to these changes is essential for the proper functioning of living organisms. Adaptation to the high degree of variability in nutrient ...
Specialized pro-resolvin mediators induce cell growth and improve wound repair in intestinal epithelial Caco-2 cell cultures.
Specialized pro-resolvin mediators (SPMs) are a superfamily of bioactive molecules synthesized from polyunsaturated fatty acids (arachidonic, eicosapentaenoic and docosahexaenoic acids) that include resolvins, protectins ...
New and Vintage Solutions to Enhance the Plasma Metabolome Coverage by Single UHPLC-ESI-MS analysis. The Not-So-Simple Process of Method Performance Evaluation in Untargeted Metabolomics
Although LC-MS untargeted metabolomics continues to expand into exiting research domains, methodological issues have not been solved yet by the definition of unbiased, standardized and globally accepted analytical protocols. ...
Metabolomics in Alzheimer's disease: The need of complementary analytical platforms for the identification of biomarkers to unravel the underlying pathology
Alzheimer's disease is a complex neurodegenerative disorder characterized by a multi-factorial etiology, not completely understood to date. In this context, the application of metabolomics is emerging in the last years ...
Phenolic Profile of Grape Canes: Novel Compounds Identified by LC-ESI-LTQ-Orbitrap-MS
Grape canes (Vitis vinifera L.) are a viticulture industry by-product with an important content of secondary metabolites, mainly polyphenols with a broad spectrum of demonstrated health benefits. Grape canes, therefore, ...
Olive pomace oil and acid oil as alternative fat sources in growing-finishing broiler chicken diets
The aim of the present study was to investigate the effect of dietary supplementation of olive pomace oil and olive pomace acid oil, which are rich in monounsaturated fatty acids (FA) but differ in free FA content, on ...

Vascular reactivity and biomarkers of endothelial function in healthy subjects exposed to acute hypobaric hypoxia
Aims: The aim of this study was to evaluate the effects of acute hypobaric hypoxia (HH) on vascular reactivity and biochemical markers associated with endothelial function (EF). Main methods: Ten healthy subjects were ...
YAT2150: Overcoming limitations of traditional amyloid dyes in aggregation studies
Amyloid fibrils, which are aggregates of misfolded proteins characterized by β-sheet-rich structures, are implicated in several neurodegenerative and systemic pathologies, including Alzheimer’s and Parkinson’s diseases and ...
Validation of biomarkers of food intake¿critical assessment of candidate biomarkers
Biomarkers of food intake (BFIs) are a promising tool for limiting misclassification in nutrition research where more subjective dietary assessment instruments are used. They may also be used to assess compliance to dietary ...
Effect of the Degree of Polymerization of Fructans on Ex Vivo Fermented Human Gut Microbiome
Prebiotic supplements are used to promote gastrointestinal health by stimulating beneficial bacteria. The aim of this study was to compare the potential prebiotic effects of fructans with increasing degrees of polymerization, ...
Glycerol production from glucose and fructose by 3T3L1 cells: a mechanism of adipocyte defense from excess substrate.
Cultured adipocytes (3T3-L1) produce large amounts of 3C fragments; largely lactate, depending on medium glucose levels. Increased glycolysis has been observed also in vivo in different sites of rat white adipose tissue. ...
Oxiesteroles: efectos biologicos, formacion, contenido y determinacion en alimentos
Se realiza una revisión bibliográfica de los aspectos nutricionales y bromatológicos de los llamados oxiesteroles. Se recogen los efectos biológicos descritos para estos compuestos, su presencia y formación en alimentos y ...
Microbial Phenolic Metabolites: Which Molecules Actually Have an Effect on Human Health?
The role of gut microbiota in human health has been investigated extensively in recent years. The association of dysbiosis, detrimental changes in the colonic population, with several health conditions has led to the ...
Oleacein and Oleocanthal: Key Metabolites in the Stability of Extra Virgin Olive Oil
Abstract: The oxidative stability of extra virgin olive oil (EVOO) depends on its composition, primarily, phenolic compounds and tocopherols, which are strong antioxidants, but also carotenoids, squalene, and fatty acids ...
Subzero temperature storage to preserve the quality attributes of veiled virgin olive oil
This study evaluated the effect of using olive pomace acid oil (OPAO) instead of crude palm oil (PO) or refined olive pomace oil (ROPO) on lipid composition, lipid oxidation, and quality of chicken meat. Broiler chickens ...
