Utilización de los polifenoles de la uva en la alimentación de las aves

In the last few years there is a growing interest in the antioxidant and antimicrobial properties of several polyphenols, especially flavonoids, which are present in several plants. Wine industry by- products (grape pomace, skin and seeds) and wine polyphenols extracts contain a wide range of these phenolic compounds. The functional properties of these polyphenols could be useful and applicable in animal nutrition. These effects have not been studied in chickens. Recent studies have shown that dietary inclusion of these grape by-products in broilers increased the oxidative stability of chicken meat in similar way that those obtained with the addition of Vitamin E. By the other hand, the use of these by-products has also been associated with a favourable modification of the intestinal microbiota by reducing the presence of several harmful bacteria and favouring other beneficial bacteEn los últimos años ha cobrado especial interés la capacidad antioxidante y antimicrobiana que poseen determinados polifenoles, especialmente flavonoides, presentes en diferentes vegetales. Los subproductos de la industria del vino (orujo, hollejo y granilla) y los extractos de polifenoles de uva poseen una amplia variedad de estos compuestos polifenólicos. Las propiedades funcionales de estos compuestos podrían ser de gran utilidad y aplicación en alimentación animal. Estos efectos han sido muy poco estudiados en aves. Estudios recientemente publicados con la incorporación de los subproductos de la uva en las raciones de las aves demuestran una mejora en la estabilidad oxidativa de los productos cárnicos del pollo similares a los obtenidos con la adición de la vitamina E. Por otro lado, su incorporación también se ha asociado con una modificación favorable de la microbiota intestinal reduciendo la presencia de determinadas bacterias perjudiciales y favoreciendo algunas bacterias beneficiosas

Results of D-IMPACT

Summary Aims:  Diagnosis IMprovement in PrimAry Care Trial (D-IMPACT) was a prospective, multicentre epidemiological study in three European countries to identify the optimal subset of simple tests applied in primary care to diagnose benign prostatic hyperplasia (BPH) in men who spontaneously present with lower urinary tract symptoms (LUTS). Methods:  Consecutive male patients aged ≥ 50 years who spontaneously attended their regular general practitioner (GP) office with LUTS were eligible for inclusion if they had not previously undergone BPH diagnostic tests or received treatment for BPH. Patients were assessed on three occasions, twice by their regular GP (visits 1 and 2) and once by a urologist (visit 3). The diagnostic accuracy of each variable was determined using the urologists' final BPH diagnosis (at visit 3) as gold-standard. Independent variables analysed were as follows: age; BPH diagnosis performed by GP in visit 1 (yes/no); probability of BPH diagnosis assessed by GP in visit 1; urinalysis (normal/abnormal); prostate-specific antigen (PSA); International Prostate Symptom Score (IPSS); diagnosis of BPH performed by GP in visit 2 (yes/no); and probability of BPH diagnosis assessed by GP in visit 2. Statistically significant variables (p 1.5 ng/ml and prostate volume ≥ 30 cm3). Among the independent variables analysed, only age, IPSS and PSA showed a statistically significant relationship with BPH diagnosis. In a logistic regression model including age, IPSS, PSA and probability of BPH (based on physical examination and symptoms), positive predictive value (PPV) was 77.1%. Exclusion of BPH probability resulted in a PPV of 75.7%. Conclusions:  A diagnostic algorithm including only objective variables (age, IPSS and PSA), easily implemented in any GP office, allows GPs to accurately diagnose BPH in approximately three-quarters of patients spontaneously reporting LUTS

Picture Power? The Contribution of Visuals and Text to Partisan Selective Exposure

Today’s high-choice media environment allows citizens to select news in line with their political preferences and avoid content counter to their priors. So far, however, selective exposure research has exclusively studied news selection based on textual cues, ignoring the recent proliferation of visual media. This study aimed to identify the contribution of visuals alongside text in selective exposure to pro-attitudinal, counter-attitudinal and balanced content. Using two experiments, we created a social media-style newsfeed with news items comprising matching and non-matching images and headlines about the contested issues of immigration and gun control in the U.S. By comparing selection behavior of participants with opposing prior attitudes on these topics, we pulled apart the contribution of images and headlines to selective exposure. Findings show that headlines play a far greater role in guiding selection, with the influence of images being minimal. The additional influence of partisan source cues is also considered

INDIGO : better geomagnetic observatories where we need them

The INDIGO project aims to improve the global coverage of digital observatories by deploying digital magnetometer systems in: i) Observatories where existing analog recording equipment is in need of upgrading. ii) Newly established digital observatories. iii) Existing digital observatories for the purpose of quality control and redundancy. In implementing the project and selecting suitable sites, special attention is paid to parts of the Earth devoid of magnetic observatories, increasing the reliability and long-term operation of existing observatories and cost-effective use of local resources. The Poster reviews the current status of the project. We examine the different steps and initiatives taken since the initiation of INDIGO in 2004 and assess their effectiveness in achieving progress towards our aims of improving global coverage and enhanced data quality
