Incorporation of dietary nitrogen from fish meal and pea meal (Pisum sativum) in muscle tissue of Pacific white shrimp (Litopenaeus vannamei) fed low protein compound diets
Stable isotope analyses were applied to explore the relative dietary nitrogen contributions from fish meal and pea meal (Pisum sativum) to muscle tissue of Pacific white shrimp postlarvae (141 ± 31 mg) fed low protein diets having different proportions of both ingredients as the sole dietary protein sources. A negative control diet was formulated to contain 100% pea meal and six more isoproteic diets to have decreasing levels of pea meal-derived nitrogen: 95, 85, 70, 55, 40 and 0 % of the initial level. Growth rates were negatively correlated to dietary pea protein inclusion due to progressive essential amino acid deficiencies (sulfur amino acids, threonine, lysine, histidine). The nitrogen turnover rate significantly increased in muscle tissue of shrimps fed diets having high levels of pea meal; however, contrary to observations from a previous study using soy protein , the relative contributions of dietary nitrogen from pea meal to shrimp muscle tissue were equal or higher than expected contributions established by the dietary formulations. Results highlight the effectiveness of stable isotope analysis in assessing the nutritional contributions of alternative ingredients for aquaculture feeds and the potential suitability of pea as a source of protein (provided the diets are nutritionally balanced)
Application of stable isotope analysis to differentiate shrimp extracted by industrial fishing or produced through aquaculture practices.
Carbon and nitrogen stable isotope values were determined in Pacific white shrimp (Litopenaeus vannamei) with the
objective of discriminating animals produced through aquaculture practices from those extracted from the wild. Farmed animals were collected at semi-intensive shrimp farms in Mexico and Ecuador. Fisheries-derived shrimps were caught in different fishing areas representing two estuarine systems and four open sea locations in Mexico and Ecuador. Carbon and nitrogen stable isotope values (13CVPDB and 15NAIR) allowed clear differentiation of wild from farmed animals. 13CVPDB and
15NAIR values in shrimps collected in the open sea were isotopically enriched (−16.99‰ and 11.57‰), indicating that these organisms belong to higher trophic levels than farmed animals. 13CVPDB and 15NAIR values of farmed animals (−19.72‰ and 7.85‰, respectively) partially overlapped with values measured in animals collected in estuaries (−18.46‰ and 5.38‰, respectively).
Canonical discriminant analysis showed that when used separately and in conjunction, 13CVPDB and I5NAIR values were powerful discriminatory variables and demonstrate the viability of isotopic evaluations to distinguish wild-caught shrimps from aquaculture shrimps. Methodological improvements will define a verification tool to support shrimp traceability protocols

Axial Spondyloarthritis: Patient-Reported Impact in Europe
This open access book provides an overview of the International Map of Axial Spondyloarthritis (IMAS) project -focusing on Europe-, a wide-ranging, multi-disciplinary collaboration between academic groups, Health Care Professionals (HCPs), patient organizations and Novartis. IMAS was conceived to improve knowledge of Axial Spondyloarthritis (axSpA) and raise awareness of its heavy burden globally. By asking more than 2,000 patients across Europe about the impact of axSpA on multiple aspects of their life, the full extent of this disease was investigated from a direct patient perspective. This allowed a unique understanding of how living with axSpA affects the daily lives and well-being of patients, and how this varies between European countries. Axial Spondyloarthritis: Patient-Reported Impact in Europe highlights opportunities for progressing quality patient care to be applied to health services globally. HCPs, policy makers and patients will find this book to be an indispensable resource for improving the understanding of this chronic condition, including patients’ clinical outcomes, the protection of those at risk of psychological distress, and the economic burden on patients and society
La importancia nutricional de la productividad natural en operaciones de pre-cría y engorda de camarón indicada mediante isótopos estables
La productividad natural de los estanques de cultivo semi-intensivo está frecuentemente representada por una gran cantidad de elementos que continuamente aportan nutrientes a los organismos en cultivo. Estos componentes dietarios pueden exhibir firmas isotópicas naturalmente distintas y por lo tanto permiten establecer relaciones entre los organismos consumidores y sus respectivas dietas. Los valores isotópicos pueden medirse e integrarse en modelos simples para cuantificar la contribución relativa de múltiples fuentes nutritivas al crecimiento del organismo consumidor. De esta forma, es posible estimar la contribución dietaria relativa de los diversos elementos presentes ya sea en los ambientes naturales de cultivo o incluidos en dietas y regímenes de alimentación experimentales. Los análisis isotópicos proveen información no solo acerca de la selección, captura e ingestión de material, sino también acerca de las cantidades de nutrientes asimilados en los tejidos del consumidor. El presente documento resume la importancia nutricional que presenta para el camarón algunos de los diversos elementos encontrados en la productividad natural. De la misma forma, se expone una síntesis de los resultados encontrados en estudios en los que se han utilizado valores isotópicos para determinar las contribuciones de diversos elementos nutricionales al crecimiento del camarón en las fases de pre-cría y engorda
Apparent digestibility of dry matter, crude protein, and amino acids of six rendered by-products in juvenile Litopenaeus vannamei
Apparent digestibility coefficients (ADC) of dry matter, crude protein (CP), and amino acids (AA) were evaluated in diets with six rendered by-products used to feed juvenile Pacific white shrimp: two poultry meals (poultry meal 1, 69% CP; poultry meal 2, 72% CP), two
feather meals (89% CP), one blood meal (96% CP), and one pork meal (57% CP). Experimental diets were formulated with 30% of the test ingredient and 70% of a commercial diet supplemented with 1% of chromium oxide as inert marker. AA contents in ingredients, diets, leached
diets, and feces were determined by high performance liquid chromatography. Preprandial AA losses attributed to leaching were higher in the blood meal diet (15%) and pork meal diet (10%). Poultry meal diets 1 and 2 showed mean AA losses of 3% and 5%, respectively, while the
reference diet had a mean AA leaching of 6%. The AA that had the highest leaching rates were lysine (21%), methionine (15%), and histidine (12%). The ADC of dry matter was higher for poultry meals 1 (70%) and 2 (73%), followed by pork meal (69%), feather meals (61%), and
blood meal (57%). The digestibility of CP was higher for poultry meals (78–80%), followed by pork meal (76%), and blood meal and feather meals (65–67%). The digestibility of CP in the reference diet (83%) was higher than that observed for all the animal by-product meals except
the poultry meals. The ADC of the sum of AA adjusted for nutrient leaching fluctuated from 65% for blood meal to 80% for poultry meals
El nivel del razonamiento lógico matemático de los estudiantes del Instituto Superior Tecnológico Público Cutervo de la Región Cajamarca
El objetivo de este trabajo de investigación fue hacer un diagnóstico del nivel del razonamiento lógico matemático de los estudiantes que ingresaban al Instituto Superior Tecnológico Público Cutervo, puesto que deseábamos conocer el estado del desarrollo de esta capacidad tan importante en la vida de toda persona y en especial de futuros profesionales. Sabemos que, en la actualidad, en la mayoría de los países desarrollados, para el ingreso a las universidades ya no se evalúan conocimientos sino el nivel de las capacidades, en resumen, el nivel del razonamiento lógico matemático y el razonamiento verbal. En nuestro caso, se utilizó una prueba objetiva de selección múltiple que se aplicó a los estudiantes que habían recién ingresado a la institución. Los resultados han demostrado que el nivel del razonamiento lógico matemático de la muestra es regular, con un promedio de 14,76.The objective of this research work was to make a diagnosis of the level of mathematical logical reasoning of the students who entered the Cutervo Public Higher Technological Institute, since we wanted to know the state of the development of this capacity that is so important in the life of every person and in special for future professionals. We know that, currently, in most developed countries, knowledge is no longer evaluated for admission to universities, but rather the level of skills, in short, the level of mathematical logical reasoning and verbal reasoning. In our case, an objective multiple-choice test was applied to students who had just entered the institution. The results have shown that the level of mathematical logical reasoning of the sample is regular, with an average of 14.76
