Caracterización funcional de almidones de plátano cuadrado (Musa balbisiana Colla)

Resistant starch (RS) stands out for its properties related to human health. In the digestive system it provides the benefits of dietary fiber and acts as a prebiotic. New sources of resistant starch are being investigated. The proximal composition, functional properties and microbiological quality of square banana starches (Musa balbisiana Colla) were determined. The fruits were harvested in plantations of Tabasco, Mexico, with degree of maturity type I. The flour was elaborated by drying in an oven. The extraction of the starches was carried out using a wet method and the resistant starches, by enzymatic method. The concentration of bacterial groups was quantified by the surface culture method. The solubility, swelling power and water absorption patterns were evaluated at 60, 70, 80 and 90 ºC. Products with low moisture content were obtained: flour (7.45 ± 0.28), native starch (9.28 ± 0.55) and sterilized starch (10.82 ± 0.10). In the protein content, the highest concentration was observed in the flour (4.44 ± 0.40), followed by the native starch (1.19 ± 0.04), RS2 (0.13 ± 0.01) and RS3 (0.19 ± 0.01). Functional properties are related to different factors, such as temperature, granule size, amylose content and type of resistant starch. RS3 presented the best functional properties and good microbiological quality. The native starch presented the highest microbial load. RS2 and the sterilized starch presented the lowest values of the functional properties

Identificación genética de bacterias ácido lácticas nativas en leche cruda de vaca y queso Poro artesanal

El sabor y aroma de los quesos se debe a la diversidad de compuestos producidos por los microorganismos, que actúan durante el cuajado de la leche y maduración de los quesos. El objetivo aquí fue, identificar bacterias ácido lácticas en leche cruda de vaca y el queso Poro artesanal que se elabora en Tabasco, México. El aislamiento de las bacterias lácticas (BAL) se realizó sobre agar MRS, LBS y M17. Las cepas aisladas fueron caracterizadas por morfología, tinción de Gram, pruebas bioquímicas y crecimiento a diferentes concentraciones de cloruro de sodio (NaCl) y pH. La identificación genética inició con la extracción del ADN, amplificación del gen ARN ribosomal 16S con cebadores universales para bacterias. Las amplificaciones resultantes fueron secuenciadas en un laboratorio externo. Se identificaron 31 BAL, donde se observó Lactobacillus rhamnosus (38,71%), Lactobacillus fermentum (29,03%), Lactobacillus plantarum (6,45%) en muestras de leche y queso. También se identificó Enterococcus durans (6,45%) en leche y Lactobacillus farciminis (3,23%) en queso Poro. Todas reportadas por sus características biotecnológicas, tal como cultivos iniciadores. Estos resultados serán la base para formular y estabilizar un cultivo iniciador, que pueda ser utilizado en la elaboración del queso Poro con leche pasteurizada

Shells and humans: molluscs and other coastal resources from the earliest human occupations at the Mesolithic shell midden of El Mazo (Asturias, Northern Spain)

Human populations exploited coastal areas with intensity during the Mesolithic in Atlantic Europe, resulting in the accumulation of large shell middens. Northern Spain is one of the most prolific regions, and especially the so-called Asturian area. Large accumulations of shellfish led some scholars to propose the existence of intensification in the exploitation of coastal resources in the region during the Mesolithic. In this paper, shell remains (molluscs, crustaceans and echinoderms) from stratigraphic units 114 and 115 (dated to the early Mesolithic c. 9 kys cal BP) at El Mazo cave (Asturias, northern Spain) were studied in order to establish resource exploitation patterns and environmental conditions. Species representation showed that limpets, top shells and sea urchins were preferentially exploited. One-millimetre mesh screens were crucial in establishing an accurate minimum number of individuals for sea urchins and to determine their importance in exploitation patterns. Environmental conditions deduced from shell assemblages indicated that temperate conditions prevailed at the time of the occupation and the morphology of the coastline was similar to today (rocky exposed shores). Information recovered relating to species representation, collection areas and shell biometry reflected some evidence of intensification (reduced shell size, collection in lower areas of exposed shores, no size selection in some units and species) in the exploitation of coastal resources through time. However, the results suggested the existence of changes in collection strategies and resource management, and periods of intense shell collection may have alternated with times of shell stock recovery throughout the Mesolithic.This research was performed as part of the project “The human response to the global climatic change in a littoral zone: the case of the transition to the Holocene in the Cantabrian coast (10,000–5000 cal BC) (HAR2010-22115-C02-01)” funded by the Spanish Ministry of Economy and Competitiveness.

Role of age and comorbidities in mortality of patients with infective endocarditis

Purpose: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. Methods: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015. Patients were stratified into three age groups:<65 years, 65 to 80 years, and = 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. Results: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 = 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients =80 years who underwent surgery were significantly lower compared with other age groups (14.3%, 65 years; 20.5%, 65-79 years; 31.3%, =80 years). In-hospital mortality was lower in the <65-year group (20.3%, <65 years;30.1%, 65-79 years;34.7%, =80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%, =80 years; p = 0.003).Independent predictors of mortality were age = 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI = 3 (HR:1.62; 95% CI:1.39–1.88), and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared, the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. Conclusion: There were no differences in the clinical presentation of IE between the groups. Age = 80 years, high comorbidity (measured by CCI), and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group

Post-Franco Theatre

In the multiple realms and layers that comprise the contemporary Spanish theatrical landscape, “crisis” would seem to be the word that most often lingers in the air, as though it were a common mantra, ready to roll off the tongue of so many theatre professionals with such enormous ease, and even enthusiasm, that one is prompted to wonder whether it might indeed be a miracle that the contemporary technological revolution – coupled with perpetual quandaries concerning public and private funding for the arts – had not by now brought an end to the evolution of the oldest of live arts, or, at the very least, an end to drama as we know it

Efecto Del Almidón De Plátano Cuadrado Musa Balbisiana Colla En El Rendimiento, Retención De Agua Y Aceptación Sensorial En Jamón Cocid

Los almidones no convencionales se han utilizado con éxito en la formulación de productos cárnicos, al brindar textura y escaso sabor a un menor costo. Aquí el objetivo fue, evaluar el efecto del almidón de plátano cuadrado Musa balbisiana Colla sobre el rendimiento, retención de agua y aceptación sensorial en el jamón cocido. El almidón de plátano (madurez tipo I) se extrajo con una metodología recomendada. Se elaboró jamón cocido con carne de cerdo y se adicionó almidón de plátano. A partir de un diseño experimental factorial 22: concentración de almidón (factor A) 10 % y 20 %, y tiempo de masajeo de la carne (factor B) de 16 y 30 min. Resultando un total de cuatro tratamientos: T1, T2, T3 y T4 (n=3). Para tener un referente, se elaboró un jamón cocido adicionado con almidón de maíz. La concentración de almidón de plátano y el mayor tiempo de masajeo (30 min), registró relación positiva en el rendimiento del jamón cocido (121.4 ± 0.36 %). La capacidad de retención de agua aumentó de acuerdo con la concentración de almidón y el tiempo de masajeo, independiente del origen del ligante adicionado (almidón de plátano o almidón de maíz). El jamón cocido adicionado con almidón de plátano fue el más aceptado y mejor evaluado. Por lo que, este almidón puede ser utilizado como un aditivo alimentario para la producción del jamón cocido. Non-conventional starches have been successfully used in the formulation of meat products, providing texture and low flavor at a lower cost. The objective here was to evaluate the effect of square banana Musa balbisiana Colla starch on yield, water retention and sensory acceptability in cooked ham. Banana starch (maturity type I) was extracted using a recommended methodology. Cooked ham (with pork meat) was prepared with banana starch. Based on a 22 factorial experimental design: starch concentration (factor A) 10 % and 20 %, and meat massaging time (factor B) of 16 and 30 min, resulting in a total of four treatments: T1, T2, T3 and T4 (n=3). In order to have a reference, a cooked ham was prepared with corn starch added. The concentration of banana starch and the longer massaging time (30 min) were positively related to the yield of cooked ham (121.4 ± 0.36 %). Water retention capacity increased according to starch concentration and massaging time, independent of the origin of the added binder (banana starch or cornstarch). The cooked ham added with banana starch was the most accepted and best evaluated. Therefore, this starch can be used as a food additive to produce cooked ham

Benito Pérez Galdós

In Galdós\u27 time, the tensions between such diverse phenomena as coins and credit, free trade and protectionist tariffs, factory work and domestic economy, masculine and feminine, and private and public exacerbated friction among peoples—those of pueblo and rural origins, whose voices rasped and whose bright colors raked the eye, and a nascent, insecure bourgeosie who, fearful of the masses, strove to imitate the aristocracy. Old and new converged also with the question of suffrage and citizenship to aggravate social malaise and political upheavals—Carlist wars, palace intrigues, the Revolution of 1868 and overthrow of Queen Isabel, the brief reign of Amadeo of Savoy, the aborted First Republic and the Bourbon Restoration (1875-1885), which reached Spain from England in the imported person of Alfonso XII. These turbulent events undergird the cultural, historical, and political events of the novels by Benito Pérez Galdós (1843–1920) to be discussed in this chapter. Galdós is the author of seventy-seven novels, twenty-six original plays, and numerous occasional pieces, written between 1867 and 1920. These divide into two main categories: the historical and the contemporary social novels, now more appropriately described as novels of modernity The forty-six historical novels, called Episodios nacionales, make up five series, each consisting of ten interconnected novels, except the fifth series, left unfinished. The thirty-one novels of modernity, published between 1870 and 1915, also divide into two groups: Novelas de la primera época ( Novels of the Early Period, 1870–1879) and Las novelas de la serie contemporánea ( The Contemporary Social Novels, 1881–1915). The novels of the early period comprise Galdós\u27 first attempts at novel writing, as well as four so-called thesis novels : Doña Perfecta (1876), the sequel Gloria (1876–1877), Marianela (1878), and La familia de León Roch ( The Family of León Roch, 1878–1879). The next group of novels represents what Galdós called his segunda manera —his second style, a different kind of writing ... a more sophisticated and varied mode of narrative presentation
