          Abstract

          Abstract Introduction: in April 2002, the National Food Authority of Sweden published a study in which the presence of a carcinogen was reported for the first time in experimental animals, and was identified as acrylamide. Various studies have shown that the β-glucans of Pleurotus ostreatus have diverse biological properties including antioxidant and anticancer activities. Methods: β-glucans were obtained by alkaline-acid hydrolysis from Pleurotus ostreatus, and their content was characterized by liquid chromatography. To evaluate the effect of β-glucans on the expression of glutathione, Balb/c mice were used, and 4 test groups were established. All groups were fed as usual, groups treated with acrylamide were administered the compound intragastrically at a concentration of 50 μg/mL, and β-glucan treatment was given at a concentration of 50 μg/mL. Results: no mortality was observed after exposure to the tested dose of acrylamide; only signs of peripheral neuropathy such as hyperactivity and tremors were observed after five days of experimentation, and were maintained over 30 days after the experiment. On the other hand, an increase in lipid peroxidation levels was observed in the livers of the acrylamide-treated mice, which were lower in the mice treated with β-glucans. Conclusions: results show that β-glucans may act as antioxidant agents able to protect the liver against oxidative stress as caused by the intake of acrylamide.

          Resumen Introducción: en abril de 2002, la Autoridad Nacional de Alimentos de Suecia publicó un estudio en el que se informó por primera vez de la presencia de un carcinógeno en animales experimentales, identificado como acrilamida. Diversos estudios han demostrado que los β-glucanos de Pleurotus ostreatus tienen diversas propiedades biológicas, tales como actividades antioxidantes y anticancerígenas. Métodos: los β-glucanos se obtuvieron por hidrólisis ácido-alcalina de Pleurotus ostreatus y su contenido se caracterizó por cromatografía líquida. Para evaluar el efecto de los β-glucanos sobre la expresión de glutatión, se usaron ratones Balb/c y se establecieron 4 grupos de prueba; todos los grupos se alimentaron normalmente, en los grupos tratados con acrilamida esta se administró intragástricamente a una concentración de 50 μg/mL, y el tratamiento con β-glucanos se dio a una concentración de 50 μg/mL. Resultados: no se observó mortalidad después de la exposición a la dosis probada de acrilamida; solo se observaron signos de neuropatía periférica, como hiperactividad y temblores, después de cinco días de experimentación, que se mantuvieron dentro de los 30 días posteriores al experimento. Por otro lado, se observó un aumento de los niveles de peroxidación lipídica en los hígados de los ratones tratados con acrilamida, que fueron más bajos en los ratones tratados con β-glucanos. Conclusiones: los resultados muestran que los β-glucanos podrían actuar como agentes antioxidantes y proteger el hígado contra el estrés oxidativo causado por la ingesta de acrilamida.

            Fetal origins of adult disease.

            Dr. David Barker first popularized the concept of fetal origins of adult disease (FOAD). Since its inception, FOAD has received considerable attention. The FOAD hypothesis holds that events during early development have a profound impact on one's risk for development of future adult disease. Low birth weight, a surrogate marker of poor fetal growth and nutrition, is linked to coronary artery disease, hypertension, obesity, and insulin resistance. Clues originally arose from large 20th century, European birth registries. Today, large, diverse human cohorts and various animal models have extensively replicated these original observations. This review focuses on the pathogenesis related to FOAD and examines Dr. David Barker's landmark studies, along with additional human and animal model data. Implications of the FOAD extend beyond the low birth weight population and include babies exposed to stress, both nutritional and nonnutritional, during different critical periods of development, which ultimately result in a disease state. By understanding FOAD, health care professionals and policy makers will make this issue a high health care priority and implement preventive measures and treatment for those at higher risk for chronic diseases.

              Cultivation of Pleurotus ostreatus and other edible mushrooms.

              Pleurotus ostreatus is the second most cultivated edible mushroom worldwide after Agaricus bisporus. It has economic and ecological values and medicinal properties. Mushroom culture has moved toward diversification with the production of other mushrooms. Edible mushrooms are able to colonize and degrade a large variety of lignocellulosic substrates and other wastes which are produced primarily through the activities of the agricultural, forest, and food-processing industries. Particularly, P. ostreatus requires a shorter growth time in comparison to other edible mushrooms. The substrate used for their cultivation does not require sterilization, only pasteurization, which is less expensive. Growing oyster mushrooms convert a high percentage of the substrate to fruiting bodies, increasing profitability. P. ostreatus demands few environmental controls, and their fruiting bodies are not often attacked by diseases and pests, and they can be cultivated in a simple and cheap way. All this makes P. ostreatus cultivation an excellent alternative for production of mushrooms when compared to other mushrooms.
