Characteristics of the channels and blood parameters of chickens complemented with chromium and their productive acting

P?ginas 15-19Recurso Electr?nicoEl presente trabajo evalu? el efecto del cromo en dietas para pollo de engorde con diferentes niveles de inclusi?n. Se evalu? : peso inicial, peso final, ganancia de peso, conversi?n, consumo, rendimiento en canal, peso de alas, pechuga, pernil, colesterol, glicemia y HDL. Se emplearon 96 aves distribuidas en 4 tratamientos con 4 repeticiones y 6 aves en cada una, alimentadas con cromo a partir del d?a noveno de vida hasta el d?a 35. Los tratamientos 1, 2, 3, y 4 conten?an cromo en 0ppm, 0,5 ppm, 1 ppm, y 1,5 ppm en la dieta respectivamente. No se encontraron diferencias significativas (p0,05) en el consumo de alimento. Pese a lo anterior los mejores resultados obtenidos se presentaron en los tratamientos 2. Peso final (1983.3 g vs 2032,3 g), ganancia de peso (1811,9 g vs 1859,9 g ), conversi?n (1,666 vs 1,670). Con respecto al consumo el tratamiento control presento consumo m?s bajo (3305 g vs 3395 g), y rendimiento en canal el tratamiento control presento mejor rendimiento con respecto a los dem?s tratamientos (71,8 % vs 71,3 %). Con respecto a los cortes los resultados favorecen a los tratamientos con cromo, alas (172,9 g vs 181,5 g), pechugas (536,3 g vs 545,1 g), perniles (699,1 g vs 708,6 g). Se determin? que el tratamiento 2 presenta los mejores resultados econ?micos.ABSTRACT. This project aims to evaluate the effect of chromium in breeding chicken diets with different inclusion levels. The items evaluated were: initial weight, final weight, increase in weight, conversion, consumptions, carcass development, wings, breasts, and legs weight, cholesterol, blood sugar, and HDL. A sample of 96 birds was used distributed in 4 treatments with 4 repetitions and 6 birds each, fed with chromium since the 9th day of life until day 35. Treatments 1, 2, 3 and 4 had chromium concentrations of 0 ppm, 0,5 ppm, 1 ppm, and 1,5 ppm in their diet respectively. No significant differences were found (p0,05) was food consumption. Nevertheless, the best results were found in birds subjected to treatment 2: Final weight (1983,3 g vs. 2032,3 g), increase in weight (1811,9 g vs. 1859,9 g), and conversion (1.666 vs. 1.670). Regarding consumption, the control treatment presented the lowest rate (3305 g vs. 3395 g); and regarding yield in channel, the control treatment presented better outputs than the others (71,8 % vs 71,3 %). Examining other criteria, outputs favor chromium treatments: wings (172,9 g vs. 181,5 g), breasts (536,3 g vs. 545,1 g), and legs (669,1 g vs. 708,6 g). Therefore, it was determined that treatment 2 brings better economic results

Pan-cancer analysis of whole genomes

Cancer is driven by genetic change, and the advent of massively parallel sequencing has enabled systematic documentation of this variation at the whole-genome scale(1-3). Here we report the integrative analysis of 2,658 whole-cancer genomes and their matching normal tissues across 38 tumour types from the Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium of the International Cancer Genome Consortium (ICGC) and The Cancer Genome Atlas (TCGA). We describe the generation of the PCAWG resource, facilitated by international data sharing using compute clouds. On average, cancer genomes contained 4-5 driver mutations when combining coding and non-coding genomic elements; however, in around 5% of cases no drivers were identified, suggesting that cancer driver discovery is not yet complete. Chromothripsis, in which many clustered structural variants arise in a single catastrophic event, is frequently an early event in tumour evolution; in acral melanoma, for example, these events precede most somatic point mutations and affect several cancer-associated genes simultaneously. Cancers with abnormal telomere maintenance often originate from tissues with low replicative activity and show several mechanisms of preventing telomere attrition to critical levels. Common and rare germline variants affect patterns of somatic mutation, including point mutations, structural variants and somatic retrotransposition. A collection of papers from the PCAWG Consortium describes non-coding mutations that drive cancer beyond those in the TERT promoter(4); identifies new signatures of mutational processes that cause base substitutions, small insertions and deletions and structural variation(5,6); analyses timings and patterns of tumour evolution(7); describes the diverse transcriptional consequences of somatic mutation on splicing, expression levels, fusion genes and promoter activity(8,9); and evaluates a range of more-specialized features of cancer genomes(8,10-18).Peer reviewe

Data from an International Multi-Centre Study of Statistics and Mathematics Anxieties and Related Variables in University Students (the SMARVUS Dataset)

This large, international dataset contains survey responses from N = 12,570 students from 100 universities in 35 countries, collected in 21 languages. We measured anxieties (statistics, mathematics, test, trait, social interaction, performance, creativity, intolerance of uncertainty, and fear of negative evaluation), self-efficacy, persistence, and the cognitive reflection test, and collected demographics, previous mathematics grades, self-reported and official statistics grades, and statistics module details. Data reuse potential is broad, including testing links between anxieties and statistics/mathematics education factors, and examining instruments’ psychometric properties across different languages and contexts
