Eating patterns are associated with biomarkers in a selected population of university students and employees.
2011
AbstractThe association between diet and CVD cannot be assigned to a single nutrient, but rather to a set of nutrients and non-nutrients, and eating pattern analyses have become an important tool in investigation of this relationship. Our objective was to investigate eating patterns in relation to nutrient intake and serum concentration of folate, vitamin B12 and TAG in ninety-five healthy adult participants. Dietary information was collected by an FFQ, and eating patterns were obtained by principal components analyses of thirty-three food groups. Three eating patterns were extracted, a sweet eating pattern identified by intakes of cakes, snacks, sugar-sweetened drinks and chocolates; a pru…
The efficacy and safety of nutrient supplements in the treatment of mental disorders: a meta‐review of meta‐analyses of randomized controlled trials
2019
The role of nutrition in mental health is becoming increasingly acknowledged. Along with dietary intake, nutrition can also be obtained from "nutrient supplements", such as polyunsaturated fatty acids (PUFAs), vitamins, minerals, antioxidants, amino acids and pre/probiotic supplements. Recently, a large number of meta-analyses have emerged examining nutrient supplements in the treatment of mental disorders. To produce a meta-review of this top-tier evidence, we identified, synthesized and appraised all meta-analyses of randomized controlled trials (RCTs) reporting on the efficacy and safety of nutrient supplements in common and severe mental disorders. Our systematic search identified 33 me…
Valoración de los niveles materno-fetales de 25-OH Vitamina D y grado de mineralización ósea del recién nacido
2018
Introducción: La Vitamina D (VD) se obtiene mayoritariamente de la síntesis endógena cutánea tras exposición solar y, en menor medida, del aporte dietético. Su función fundamental es asegurar unos niveles séricos adecuados de calcio y fósforo que permitan una adecuada mineralización ósea. Su déficit durante la edad pediátrica causa raquitismo y podría afectar a la adquisición del pico de masa ósea durante la pubertad, lo que ha motivado diversas recomendaciones para su suplementación. Pero hasta la fecha se desconoce qué efecto pueden tener los niveles bajos de 25(OH)VD o calcidiol de las embarazadas sobre la mineralización del esqueleto fetal. Objetivo Principal: Conocer si existe relación…
Retinoids as a Perspective in Treatment of Alzheimer’s Disease
2010
<i>Background:</i> In the past, we demonstrated that the disintegrin metalloproteinase ADAM10 has α-secretase activity in vitro and in cultured cells. We also found out that moderate overexpression of this proteinase inhibits Aβ peptide production and prevents the formation of amyloid plaques in an Alzheimer’s disease (AD) mouse model. Moreover, it corrects early hippocampal defects like LTP impairment and increases cortical synaptogenesis. <i>Objective:</i> Upregulation of ADAM10 might be an alternative approach concerning AD therapy. Our current research therefore focuses on substances and/or pathways which regulate ADAM10 gene expression. <i>Methods:</i&g…
Analysis of gene expression in relation to concentrations of antioxidants, vitamin B12, folate and homocysteine in patients with type 2 diabetes mell…

La Diabetes Mellitus (DM) constituye una de las causas más importantes de pérdida de visión y de la calidad de vida relacionada con la visión en todo el mundo, puesto que presenta un gran número de complicaciones en su desarrollo, siendo una de las más importantes la retinopatía diabética (RD). En la actualidad la DM se considera una pandemia, puesto que su prevalencia no deja de aumentar. La RD es una patología ocular en auge, causa de ceguera en todo el mundo con una prevalencia del 34,6%. Las personas con RD a menudo no se dan cuenta de los cambios en su visión durante las primeras etapas de la enfermedad pero, a medida que avanza, causa una pérdida importante de visión e incluso ceguera…
Hypovitaminosis D in Young Basketball Players: Association with Jumping and Hopping Performance Considering Gender
2021
This study aimed to verify whether a group of young well-trained basketball players presented deficiencies in vitamin D concentration, and to analyze whether there was an association between vitamin D concentration and jumping and hopping performance. Gender differences were considered. Twenty-seven players from an international high-level basketball club (14 female, 16.00 ± 0.55 years
Valorization of kiwi agricultural waste and industry by-products by recovering bioactive compounds and applications as food additives : a circular ec…
2021
Currently, agricultural production generates large amounts of organic waste, both from the maintenance of farms and crops (agricultural wastes) and from the industrialization of the product (food industry waste). In the case of Actinidia cultivation, agricultural waste groups together leaves, flowers, stems and roots while food industry by-products are represented by discarded fruits, skin and seeds. All these matrices are now underexploited and so, they can be revalued as a natural source of ingredients to be applied in food, cosmetic or pharmaceutical industries. Kiwifruit composition (phenolic compounds, volatile compounds, vitamins, minerals, dietary fiber, etc.) is an outstanding basis…
To B or Not to B: Comparative Genomics Suggests
2018
Insect lineages feeding on nutritionally restricted diets such as phloem sap, xylem sap, or blood, were able to diversify by acquiring bacterial species that complement lacking nutrients. These bacteria, considered obligate/primary endosymbionts, share a long evolutionary history with their hosts. In some cases, however, these endosymbionts are not able to fulfill all of their host's nutritional requirements, driving the acquisition of additional symbiotic species. Phloem-feeding members of the insect family Aleyrodidae (whiteflies) established an obligate relationship with Candidatus Portiera aleyrodidarum, which provides its hots with essential amino acids and carotenoids. In addition, ma…
MAHONIA AQUIFOLIUM AS A PROMISING RAW MATERIAL FOR THE FOOD INDUSTRY
2017
The development of the food industry leads to the expansion of the range of processed raw materials. Mahonia aquifolium today can be attributed to the non-traditional agricultural plants. However, the analysis of the chemical composition of the fruits showed that they contain significant amount of carbohydrates, vitamin C, various minerals, which recommend it for a wider use in the diet. Also due to the presence in the fruits of Mahonia aquifolium anthocyanins can extend of the use as raw material for natural anthocyanin dyes obtaining.
Functional investigation and applications of the acetylesterase activity of the Citrus sinensis (L.) Osbeck peel
2020
The hydrolysis of acetyl moieties on a set of commercially relevant substrates was performed by employing the whole tissue of Citrus sinensis (L.) Osbeck peel as an efficient biocatalyst in mild reaction conditions with high degree of regioselectivity. The reaction is done in aqueous media and the product is easily recovered. Optimal reaction conditions were deduced and two practical applications were investigated: the elaboration of acetylglicerols and the preparation of vitamin K1 precursor. Peel waste (flavedo and albedo) from orange juice manufacturing was successfully employed as a biocatalyst.
