COMPOSICIÓN MICOQUÍMICA Y ACTIVIDAD ANTIOXIDANTE DE LA SETA Pleurotos ostreatus EN DIFERENTES ESTADOS DE CRECIMIENTO / Mycochemical composition and antioxidant activity of Pleurotus ostreatus mushroom in different growth stages

RESUMEN Pleurotus sp. es un género de basidiomicetos ampliamente distribuido a nivel mundial, con especies que revisten importancia, no solo desde el punto de vista comercial por su valor nutricional, sino también por sus propiedades medicinales. Sin embargo, aún son insuficientes los estudios micoquímicos y se desconoce su relación con las propiedades antioxidantes de bioproductos obtenidos de estas setas durante diferentes estados de crecimiento. En el presente trabajo, se determinó el contenido de proteínas, carbohidratos, azúcares reductores, fenoles totales y flavonoides, así como la actividad antioxidante in vitro (ensayos de captación de radicales DPPH y estimación del poder reductor) de extractos acuosos de Pleurotus ostreatus en dos estados de crecimiento (primordios y cuerpos fructíferos maduros) durante la fermentación sólida. El contenido de proteínas, azúcares reductores y flavonoides fue superior en el extracto acuoso de cuerpos fructíferos maduros, mientras que los carbohidratos y fenoles totales fueron mayores en el extracto de primordios. Los valores de EC50 en los ensayos de DPPH y los de poder reductor fueron de 1,72 mg/mL y 3,27 mg/mL para el extracto de primordios y de 0,44 mg/mL y 0,48 mg/mL para el de cuerpos fructíferos maduros, respectivamente. Los resultados sugieren que las propiedades antioxidantes de extractos acuosos de Pleurotus ostreatus (primordios y cuerpos fructíferos maduros) reflejan las variaciones en la concentración de moléculas bioactivas, teniendo en cuenta las particularidades fisiológicas de las fases de crecimiento. Ello podría resultar de utilidad para el diseño de protocolos de obtención de bioproductos de Pleurotus ostreatus con aplicaciones potenciales como antioxidantes en las industrias alimentaria y farmacéutica.

ABSTRACT Pleurotus sp. is a genus of Basidiomycetes widely distributed worldwide, with species that are important not only from the commercial point of view for its nutritional value, but also for their medicinal properties. However, mycochemical studies and the relationship with the antioxidant properties of bioproducts obtained from these mushrooms during different growth stages are still insufficient. In this work, the content of proteins, carbohydrates, reducing sugars, total phenols and flavonoids was determined, as well as the in vitro antioxidant activity (tests of scavenging DPPH and reducing power estimation) of aqueous extracts of Pleurotus ostreatus in different growth stages (primordia and mature fruiting bodies) during the solid fermentation. The content of proteins, reducing sugars and flavonoids was higher in the aqueous extract ofmature fruiting bodies, while carbohydrates and total phenols were increased in the extract ofprimordia. The EC50 values in the DPPH and reducing power assays were 1.72 mg/mL and 3.27 mg/mL for primordia extract and 0.44 mg/mL and 0.48 mg/mL in the case of mature fruiting bodies extract, respectively. The results suggest that the antioxidant properties of Pleurotus ostreatus aqueous extracts (primordia and mature fruiting bodies), reflected the variations in the concentration of bioactive molecules, taking into account the physiological characteristics of the growth phases. This could be useful in designing protocols for obtaining bioproducts from Pleurotus ostreatus with potential applications as antioxidant in food and pharmaceutical industries.

Resveratrol in Alzheimers disease: a review of pathophysiology and therapeutic potential / Resveratrol na doença de Alzheimer: uma revisão sobre fisiopatologia e potencial terapêutico

ABSTRACT Background: Alzheimer's disease (AD) is a neurodegenerative disorder characterized by progressive and irreversible loss of cognitive function. The presence of senile plaques is one of the pathological markers of the disease and is associated with the onset of neuroinflammatory mechanisms. The exact pathophysiology of AD has not been completely understood, and there are no curative therapies yet. Resveratrol (3,5,4'-trihydroxy-trans-stilbene) is a polyphenol that is noted for its antioxidant and anti-inflammatory properties. Objective: To review the role of resveratrol in the pathophysiological aspects of AD. Methods: This study carried out a literature review using PubMed/Medline, Virtual Health Library (VHL), Web of Sciences, SCOPUS and the Cochrane Library databases. Original research articles, describing both in vitro and in vivo experiments, published between 2008 and 2018, were included. Results: We identified 667 articles, of which 619 were excluded because they were repeated or did not follow the inclusion criteria. The present study includes the remaining 48 articles. Discussion: Resveratrol demonstrates beneficial and protective effects in AD models and seems to provide a promising therapeutic alternative. Conclusion: Although resveratrol appears to mitigate some pathophysiological aspects of AD, further studies are needed to prove the safety and efficacy of this compound in humans.

RESUMO Introdução: A doença de Alzheimer (DA) é neurodegenerativa e caracterizada por perda progressiva e irreversível da função cognitiva. A presença de placas senis é um dos marcadores patológicos da doença e está associada ao aparecimento de mecanismos neuroinflamatórios. A fisiopatologia exata da DA ainda não é completamente compreendida, e ainda não existem terapias curativas. O resveratrol (3,5,4'-trihidroxi-trans-estilbeno) é um polifenol conhecido por suas propriedades antioxidantes e anti-inflamatórias. Objetivo: Revisar o papel do resveratrol nos aspectos fisiopatológicos da DA. Métodos: Este estudo realizou uma revisão narrativa da literatura a partir das bases de dados PubMed/Medline, Biblioteca Virtual em Saúde (BVS), Web of Science, SCOPUS e Cochrane Library. Foram incluídos artigos originais, realizados in vitro e in vivo, publicados entre 2008 e 2018. Resultados: Foram identificados 667 artigos, dos quais 619 foram excluídos por estarem repetidos ou não se enquadrarem nos critérios de inclusão. O presente estudo inclui os 48 artigos restantes. Discussão: O resveratrol demonstra efeitos benéficos e protetores em modelos de DA, bem como parece fornecer uma alternativa terapêutica promissora. Conclusão: Embora o resveratrol pareça atenuar alguns aspectos fisiopatológicos da DA, são necessários mais estudos para comprovar a segurança e a eficácia deste composto em seres humanos.

Autocuidado y prevención del cáncer: de los nahuas prehispánicos a los nutracéuticos contemporáneos / Self-care and cancer prevention: from pre-Hispanic Nahuas to contemporary nutraceuticals

RESUMEN Hace unos cuantos siglos, en la materia médica de los nahuas prehispánicos se incluían alimentos curativos. En la actualidad, legitimado por las ciencias experimentales, nace el nutracéutico como un alimento con propiedades curativas que se utiliza en los modelos de salud preventivos del cáncer. En este artículo, comienzo por proponer que el conocimiento prehispánico puede ser validado epistémica y metodológicamente, si se apela al particular marco conceptual de los prehispánicos. Después, arguyo que el consumo de nutracéticos, como anticancerígenos, puede pensarse como parte de medidas preventivas primarias y secundarias, así como en la comprensión de las prácticas de autocuidado en el marco de la ética contemporánea del cáncer. Concretamente, que el consumo de nutracéticos y los alimentos prehispánicos mexicanos pueden legitimarse como prácticas de bienestar y prevención cada vez más pertinentes, en la intersección de la experiencia del enfermo y de su contexto. La responsabilidad de quien padece, dentro de un contexto sociopolítico cada vez más estructurado por las exigencias de vulnerabilidad del mercado terapéutico y de las estrategias confesionarias que otorgan verdad y validez a las figuras de autoridad, se gana en la práctica de conocerse y entenderse a sí mismo en la intersubjetividad contextual.(AU)

ABSTRACT The pre-Hispanic Nahuas had a medical system that included healing foods among their therapeutic practices. Nowadays, a new knowledge is born, legitimated by experimental sciences: the nutraceutical, a food with curative properties used in cancer preventive health models. In this article, I begin by proposing that pre-Hispanic knowledge can be validated epistemically and methodologically, if we appeal to the particular conceptual framework of the pre-Hispanic. Later, that the consumption of nutraceuticals, as anti-cancer drugs, can be thought of as part of primary and secondary preventive measures, as well as in the understanding of self-care practices in the framework of contemporary cancer bioethics. Specifically, that the consumption of nutraceuticals and Mexican pre-Hispanic foods can be legitimized as increasingly relevant wellness and prevention practices, at the intersection of the patient's experience and his or her context. The responsibility of those who suffer, within a sociopolitical context that is increasingly structured by the demands of vulnerability of the therapeutic market and the confessional strategies that give truth and validity to the figures of authority over whom they suffer, is gained in the practice of knowing and understanding oneself within contextual intersubjetivity.(AU)

RESULTS: Twenty participants (mean age=43, from 23 to 66, 17F, 3M) completed the study. Participants reported having used, on average, the Lubricant Eye Drop 2.4×/day, the SteriLid 1.1×/day, and the Nutrition 3 gel caps 1×/day. There was a significant change over time (p<0.05) for OSDI (-21.2 points), SANDE (-32.4 points), NIBUT (+0.43s), eyelid margin features (-1.1 grade), meibum quality (-1.0 grade), and #MG blocked (-4.0 glands). CONCLUSION: By using a combination of TheraTears® Lubricant Eye Drop, SteriLid, and Nutrition, patients experience significant relief in both dry eye symptoms and signs.

Effects of a nutraceutical combination containing berberine (BRB), policosanol, and red yeast rice (RYR), on lipid profile in hypercholesterolemic patients: A meta-analysis of randomised controlled trials.

BACKGROUND AND AIM: A nutraceutical combination containing berberine, policosanol, and red yeast rice, largely marketed in Europe (Armolipid Plus(®)) (AP), has been reported to induce significant improvements in plasma lipids, insulin resistance and other components of the metabolic syndrome. However, literature study designs and results were heterogeneous and it was thus necessary to systematically review and meta-analyse all relevant randomised clinical trials (RCTs) to explore and quantify the effects of the dietary supplement AP on lipid profile. The aim of our meta-analysis was the evaluation of the effect of AP on lipid profile. METHODS AND RESULTS: We conducted a structures search on PubMed and Google Scholar to identify eligible articles published prior to 2015. Eleven RCTs were subjected to meta-analysis by means of random effects models using the Standardised Mean Differences approach (Hedges' method) and the Mean Differences approach as a sensitivity analysis. Data from 11 randomised clinical trials, corresponding to 1970 nutraceutical combination and 1954 control patients (3924 total patients), were included after the peer evaluation and data extraction of two independent evaluators. Heterogeneity was significant in all models. A significant effect was found for all lipid parameters. The effect size (relative change from baseline (%)) was -1.3 (9.9%) for total cholesterol, -1.17 (-13.7%) for LDL-c, +0.17 (+3.7%) for HDL-c and -0.24 (-7.0%) for Triglycerides. CONCLUSION: This meta-analysis confirms that the nutraceutical combination containing berberine, policosanol, and red yeast rice has shown to be an effective product for the improvement of the lipid profile.

The main potentialities of resveratrol for drug delivery systems

Resveratrol (RSV), a natural polyphenol found in grapes, was found to be effective in the prevention and therapy of several diseases, however, it does have unfavourable physicochemical properties. In this context, an increasing number of studies have aimed at developing novel therapeutic systems for its delivery to overcome these disadvantages. This review focuses on the mechanisms of action and therapeutic applications. Finally, it also describes some tested formulations for RSV administration, controlled release and targeting, developed with the purpose of increasing RSV bioavailability.

Esta revisão discorre sobre os mecanismos de ação e aplicações terapêuticas do RSV. Finalmente, são abordadas algumas formulações de liberação controlada e vetorizada, testadas para administração do RSV, desenvolvidas com a finalidade de aumentar a biodisponibilidade do RSV.

Alimentos funcionales, nutraceúticos y foshu: ¿vamos hacia un nuevo concepto de alimentación? / Functional foods, nutraceuticals and foshu: are we going to a novel food concept?

The increase of economic development and life expectancy of humans has aroused concerns about the health and nutrition in important groups of the population. These modifications have stimulated the development of functional foods (FF), nutraceuticals (NT) and FOSHU (Food with Specific Health Uses) in many countries around the world, mainly in those of greater development. FF are foods to which one or more healthy component has been added without changing its characteristics. The definition of FF is now incorporated into the food normative of many countries. NT is a more complex concept, because it is not referred to a food but to components of a food that can be ingested in amounts greater than those frequently consumed. NT are not pharmaceuticals since they have no therapeutic action although they may have preventive properties. FOSHU is a concept of foods with exclusive medical actions developed in Japan. This review discusses the significance of these new food concepts establishing their origins, potentialities, differences and future projections of these types of foods or food components.

El mayor desarrollo económico y las mayores expectativas de vida de la población, motivan una mayor preocupación por la salud y la alimentación a importantes grupos de la población. Estos cambios han motivado el desarrollo de los llamados alimentos funcionales (AF) y de los nutracéuticos (NT) y de los FOSHU (Food with Specific Health Uses) en varios países del mundo, principalmente en aquellos de mayor desarrollo económico. AF y NT son conceptos diferentes. Los AF son alimentos a los cuales se les ha incrementado o incorporado un componente cuyo consumo representa un beneficio de salud establecido, sin que el producto deje de ser un alimento. La definición de AF está ahora incorporada en la normativa alimentaria de varios países. NT es un concepto más complejo, ya que no se trata de alimentos pero sí de componentes de estos que se pueden consumir en mayores concentraciones que las habituales. Tampoco son medicamentos ya que no se les atribuye propiedades terapéuticas pero sí potencialmente preventivas. FOSHU es un concepto de alimentación con fines medicinales exclusivo de Japón. Este trabajo revisa el significado de estos nuevos conceptos alimentarios estableciendo sus orígenes, potencialidades, diferencias y las futuras proyecciones de este tipo de alimentos o componentes alimentarios.

Atividade antioxidante e determinação de fenóis totais, carotenoides, betacarotenos, licopeno e zinco em variedades branca, amarela e rosada de Manihot esculenta Crantz / Antioxidant activity and determination of total phenol contents, carotenoids beta-carotene, lycopene and zinc in white, yellow and pinkish varieties of Manihot Esculenta crantz

Existem variedades de mandioca que apresentam compostos como os carotenoides, beta-caroteno, licopeno e minerais importantes para a saúde humana e animal. O presente estudo avaliou a atividade antioxidante das variedades branca, amarela e rosada de Manihot esculenta, por meio de teste de DPPH e pela atividade quelante de íons ferro. Além disso, o conteúdo de fenóis totais, carotenoides, beta-caroteno, licopeno e zinco também foram determinados. Utilizando o teste de DPPH foi possível verificar que os extratos de amostras cozidas apresentaram maior atividade antioxidante (89,53% - rosada) em comparação com as amostras frescas (1,97% - branca). Para o teste de atividade quelante de íons ferro, a maior atividade foi encontrada para o extrato da variedade rosada cozida (63,43%) e a menor foi do extrato da amarela in natura (17,34%) a amostra branca não apresentou atividade. A maior concentração de fenóis e de zinco foi obtida para o extrato da variedade rosada cozida 136,12 mg EAG/g de extrato e 0,811 ppm, respectivamente, na concentração de 1000 µg/mL. A variedade rosada apresentou também maior quantidade de pigmentos, incluindo carotenoides (29,40 µg/g); beta-caroteno (9,14 µg/100g) e licopeno (68,92%). De acordo com os resultados obtidos no presente estudo, foi possível concluir que as variedades amarela e rosada de M. esculenta, apresentam quantidades de compostos fenólicos e minerais suficientes para atribuir a atividade antioxidante, podendo assim, contribuir para diminuir os danos oxidativos e serem utilizadas como nutracêuticos ou diretamente ingeridas na dieta para manter a boa saúde.

There are cassava varieties that present compounds as carotenoids, beta-carotene, lycopene and minerals important for human and animal health. The present study evaluated the antioxidant activity of the white, yellow and pinkish varieties of Manihot esculenta, by mean of the DPPH test and by the ferrous ion-chelating activity. Furthermore, the total phenols, carotenoids, beta-carotene, lycopene and zinc contents were also determined. Utilizing the DPPH test it was possible to find that extracts of boiled samples presented higher antioxidant activity (89.53% - pinkish) in comparison to the fresh samples (1.97% - white). For the ferrous ion-chelating test, the highest activity was found for the boiled pinkish variety extract (63.43%) and the lowest was for fresh yellow extract (17.34%) the white sample did not present activity. The highest concentration of total phenols and zinc content was obtained for the boiled pinkish variety extract 136.12 mg EAG/g of extract and 0,811ppm, respectively, in the concentration of 1000 µg/mL. The pinkish variety presented also higher quantity of pigments, including carotenoid (29.40 µg/g), beta-carotene (9.14 µg/100g) and lycopene (68.92%). According to the results obtained in this study it was possible to conclude that the yellow and pinkish varieties of M. esculenta present quantity of phenolic compounds and minerals sufficient to attribute the antioxidant activity and may thus contribute to reduce oxidative damage and be used as nutraceuticals or directly ingested in the diet to maintain good health.
