Efectos del tiempo de espera prefaena y la zona térmica en camión sobre la inmovilidad tónica en pollos parrilleros

La cadena de producción industrial de carne aviar incluye procedimientos que afectan el bienestar animal y consecuentemente la calidad del producto obtenido. Para evaluar el efecto del transporte y la manipulación pre-faena sobre el nivel de miedo en pollos, se han empleado pruebas de diferente tipo entre las cuales la inmovilidad tónica (IT) se destaca por su fácil determinación. El objetivo de este trabajo fue evaluar el efecto del tiempo de espera en playa de faena y la ubicación de la jaula en los camiones, sobre la duración de la IT en pollos parrilleros. El análisis comparativo se realizó mediante ANOVA en un arreglo factorial, tomándose como efectos principales el tiempo en playa de espera y la localización de la jaula en el camión. Se observaron diferencias estadísticamente significativas (p=0,0001) para IT, con valores de 248,88±12,86 s para el grupo espera larga y 167,88±13,4 s para espera corta. La zona térmica del camión también registró diferencias significativas (p=0,03) con valores de 189,06±14,74 s (zona ventilada) y 227,69±17,23 s (zona no ventilada). No se observaron diferencias significativas para el número de intentos de inducción a la inmovilidad en función del tiempo de espera y zona térmica del camión (p=0,08). No existieron correlaciones significativas entre las variables dependientes en ambos grupos experimentales. Los resultados de este trabajo permiten inferir que tiempos de espera en la playa pre-faena superiores a 3½ horas y altas temperaturas, provocan aumento en la duración de la IT, lo que la transforma en una herramienta útil para medir el estado de miedo de los pollos como consecuencia de ambas situacionesTo evaluate the effect of transport and pre-slaughter manipulation on the level of fear in chickens, different tests have been used, among them tonic immobility (TI) stands out for its easy determination. The objective of this work was to evaluate the effect of pre-slaughter lairage time and the location of the cage in transport trucks on the duration of TI in broilers. The comparative analysis was done using ANOVA in a factorial arrangement, taking as main effects the time on pre-slaughter lairage periods and the location of the cage in the truck. There were statistically significant differences (p=0.0001) for TI, with values of 248.88±12.86 s and 167.88±13.4 s for the long and short waiting periods, respectively. The thermal area of the truck also showed significant differences (p=0.03) with values of 189.06±14.74 s (ventilated area) and 227.69±17.23 s (nonventilated area). There were no significant differences in the number of attempts to induce immobility as a function of the waiting time and the thermal area of the truck (p=0.08). There were no significant correlations between the dependent variables in both experimental groups. The waiting time on holding area greater than 3½ h and a higher temperature causes a longer duration of TI, making it a useful tool to measure the grade of fear of chickens as consequence of these situationsEEA ReconquistaFil: Gallard, Eliana Andrea.

Bibliotherapy Storybook Construction: A Creative Interpretation Based on Children\u27s Goals, Wants, and Hindrances

The difficulty to continue education in the Philippines, especially in the case of children, more often than not results from lack of motivation amid poverty. This problem brought the reason for this study — to create a way to spark motivation to continue education through a bibliotherapy storybook. Data were collected among twelve respondents, ages 6-12, through questionnaires describing their goals, wants, and hindrances, using coloring materials. Through thematic analysis, results show that most of the respondents were inclined to choose social service occupations that will help provide housing for their family. However, a considerable number of them expressed fear of not being able to finish school. The results were utilized to undertake a creative interpretation, completing the production process from narrative components to digital artwork. The created bibliotherapy storybook, Ang Paligsahan ng Hari sa Kastilyo, was then validated by eight experts and received an exemplary rating as a qualified material for bibliotherapy. This study successfully provided a method on how to construct a bibliotherapy storybook from one\u27s perspective. Hence, further studies may be conducted to test the created bibliotherapy for its motivational effects from the user\u27s perspective

Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis

BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.

Epigenetic Activation of SOX11 in Lymphoid Neoplasms by Histone Modifications

Recent studies have shown aberrant expression of SOX11 in various types of aggressive B-cell neoplasms. To elucidate the molecular mechanisms leading to such deregulation, we performed a comprehensive SOX11 gene expression and epigenetic study in stem cells, normal hematopoietic cells and different lymphoid neoplasms. We observed that SOX11 expression is associated with unmethylated DNA and presence of activating histone marks (H3K9/14Ac and H3K4me3) in embryonic stem cells and some aggressive B-cell neoplasms. In contrast, adult stem cells, normal hematopoietic cells and other lymphoid neoplasms do not express SOX11. Such repression was associated with silencing histone marks H3K9me2 and H3K27me3. The SOX11 promoter of non-malignant cells was consistently unmethylated whereas lymphoid neoplasms with silenced SOX11 tended to acquire DNA hypermethylation. SOX11 silencing in cell lines was reversed by the histone deacetylase inhibitor SAHA but not by the DNA methyltransferase inhibitor AZA. These data indicate that, although DNA hypermethylation of SOX11 is frequent in lymphoid neoplasms, it seems to be functionally inert, as SOX11 is already silenced in the hematopoietic system. In contrast, the pathogenic role of SOX11 is associated with its de novo expression in some aggressive lymphoid malignancies, which is mediated by a shift from inactivating to activating histone modifications

Genome of Herbaspirillum seropedicae Strain SmR1, a Specialized Diazotrophic Endophyte of Tropical Grasses

The molecular mechanisms of plant recognition, colonization, and nutrient exchange between diazotrophic endophytes and plants are scarcely known. Herbaspirillum seropedicae is an endophytic bacterium capable of colonizing intercellular spaces of grasses such as rice and sugar cane. The genome of H. seropedicae strain SmR1 was sequenced and annotated by The Paraná State Genome Programme—GENOPAR. The genome is composed of a circular chromosome of 5,513,887 bp and contains a total of 4,804 genes. The genome sequence revealed that H. seropedicae is a highly versatile microorganism with capacity to metabolize a wide range of carbon and nitrogen sources and with possession of four distinct terminal oxidases. The genome contains a multitude of protein secretion systems, including type I, type II, type III, type V, and type VI secretion systems, and type IV pili, suggesting a high potential to interact with host plants. H. seropedicae is able to synthesize indole acetic acid as reflected by the four IAA biosynthetic pathways present. A gene coding for ACC deaminase, which may be involved in modulating the associated plant ethylene-signaling pathway, is also present. Genes for hemagglutinins/hemolysins/adhesins were found and may play a role in plant cell surface adhesion. These features may endow H. seropedicae with the ability to establish an endophytic life-style in a large number of plant species

Estimating the global conservation status of more than 15,000 Amazonian tree species

Estimates of extinction risk for Amazonian plant and animal species are rare and not often incorporated into land-use policy and conservation planning. We overlay spatial distribution models with historical and projected deforestation to show that at least 36% and up to 57% of all Amazonian tree species are likely to qualify as globally threatened under International Union for Conservation of Nature (IUCN) Red List criteria. If confirmed, these results would increase the number of threatened plant species on Earth by 22%. We show that the trends observed in Amazonia apply to trees throughout the tropics, and we predict thatmost of the world’s >40,000 tropical tree species now qualify as globally threatened. A gap analysis suggests that existing Amazonian protected areas and indigenous territories will protect viable populations of most threatened species if these areas suffer no further degradation, highlighting the key roles that protected areas, indigenous peoples, and improved governance can play in preventing large-scale extinctions in the tropics in this century
