Red deer (Cervus elaphus) : artificial feeding and early weaning

Con el objetivo principal de lograr ciervos menos susceptibles a estrés de manejo se desarrolló una técnica de crianza artificial, consistente en desmadre a 4 días del nacimiento, alimentación con sustituto lácteo en base a leche de vaca, posterior lactancia directa de cabras nodrizas y destete semiprecoz a los 4 meses de edad. Para realizar la prueba se utilizaron cuatro cervatillos del criadero de la Facultad de Ciencias Agrarias (UNCuyo). Se consiguieron resultados excelentes en cuanto a mansedumbre y un crecimiento de 177 g/ animal.día promedio del primer año de vida. La experiencia se desarrolló sin mortandad y con los animales en buen estado sanitario. Se puede concluir que la técnica fue exitosa para el logro del objetivo principal: el destete en las condiciones del ensayo siendo factible y recomendable la utilización de cabras nodrizas para facilitar el manejo y disminuir los costos de las instalaciones.An artificial raising technique was created to develop animals to lower stress susceptibility. The technique involves removing the animals from their mothers at the age of 4 days, feeding with a milk substitute based on supplemented cow's milk, and then fed by surrogate mother goats and early weaned at the age of 4 months. To carry out the trial 4 red deer were provided by the farm of Facultad de Ciencias Agrarias. Excellent results were obtained in terms of the gentleness of the animals and the average growth rate of 177 grams daily gain during the first year of life. This trial was carried out without mortality and with the animals in a good state of health. It can be concluded that the technique was succesfull in reaching its main objective, that of weaning under trial conditions is feasible and that surrogate mother goats are recommended to make handling easier and to lower factory costs.Fil: Tacchini, Fabio Marcos.

Goat kids carcasses fed with three milk replacers

Se evaluó y comparó las características de carcasas de cabritos cruza Saanen y Criollo alimentados durante 60 días con tres sustitutos lácteos diferentes: sustituto formulado en la unidad experimental FCA, sustituto comercial para terneros COM y leche de vaca LEC. Se evaluó la aceptación de la carne obtenida por parte del consumidor de Mendoza, Argentina, y la composición acídica de las carcasas. Las diversas dietas provocaron diferencias significativas (p < 0.05) en el contenido de grasa intramuscular de las carcasas: 8.08; 6.27 y 13.45 % respectivamente para FCA, COM y LEC. También se encontraron diferencias (p < 0.05) en la composición acídica, principalmente en la proporción de ácido linoleico (C18:0) en los cabritos FCA respecto de los otros, resultado de la incorporación de una alta proporción de aceites vegetales en su fórmula. No obstante los distintos contenidos grasos y composición acídica no hubo diferencias significativas de aceptación por parte del consumidor (p < 0.05).Carcasses characteristics of Criollo- Saanen goat kids fed during 60 days with three different milk replacers (goat kids replacer developed by us FCA, comercial replacer COM, and cow milk LEC), were evaluated and compared. Meat acceptability was tested and correlated with fat level and fatty acid composition of carcasses. Differences were detected in the amount of intramuscular lipids (p < 0.05) for carcasses of kid goats differently fed (8.08, 6.27 y 13.45 % for FCA, COM y LEC), and also in fatty acid composition. FCA kid goats had higher content of linoleic acid than the others, as a result of the high proportion of vegetal oils in this replacer. Although, these differences in fat content and fatty acid composition did not produce differences in the acceptance of the meat (p < 0.05).Fil: Rebora, Cecilia. Universidad Nacional de Cuyo.

Burden of acute otitis media in primary care pediatrics in Italy: A secondary data analysis from the Pedianet database

Background: The incidence of acute otitis media (AOM) vary from country to country. Geographical variations together with differences in study designs, reporting and settings play a role. We assessed the incidence of AOM in Italian children seen by primary care paediatricians (PCPs), and described the methods used to diagnose the disease.Methods: This secondary data analysis from the Pedianet database considered children aged 0 - 6 years between 01/2003 and 12/2007. The AOM episodes were identified and validated by means of patient diaries. Incidence rates/100 person-years (PY) were calculated for total AOM and for single or recurrent AOM.Results: The 92,373 children (52.1% males) were followed up for a total of 227,361 PY: 23,039 (24.9%) presented 38,241 episodes of AOM (94.6% single episodes and 5.4% recurrent episodes). The total incidence rate of AOM in the 5-year period was 16.8 episodes per 100 PY (95% CI: 16.7-16.9), including single AOM (15.9 episodes per 100 PY; 95% CI: 15.7-16.1) and recurrent AOM (0.9 episodes per 100 PY; 95% CI: 0.9-0.9). There was a slight and continuously negative trend decrease over time (annual percent change -4.6%; 95%CI: -5.3, -3.9%). The AOM incidence rate varied with age, peaking in children aged 3 to 4 years (22.2 episodes per 100 PY; 95% CI 21.8-22.7). The vast majority of the AOM episodes (36,842/38,241, 96.3%) were diagnosed using a static otoscope; a pneumatic otoscope was used in only 3.7%.Conclusions: Our data fill a gap in our knowledge of the incidence of AOM in Italy, and indicate that AOM represents a considerable burden for the Italian PCP system. Educational programmes concerning the diagnosis of AOM are needed, as are further studies to monitor the incidence in relation to the introduction of wider pneumococcal conjugate vaccines

Computational models in plant-pathogen interactions: the case of Phytophthora infestans

<p>Abstract</p> <p>Background</p> <p><it>Phytophthora infestans </it>is a devastating oomycete pathogen of potato production worldwide. This review explores the use of computational models for studying the molecular interactions between <it>P. infestans </it>and one of its hosts, <it>Solanum tuberosum</it>.</p> <p>Modeling and conclusion</p> <p>Deterministic logistics models have been widely used to study pathogenicity mechanisms since the early 1950s, and have focused on processes at higher biological resolution levels. In recent years, owing to the availability of high throughput biological data and computational resources, interest in stochastic modeling of plant-pathogen interactions has grown. Stochastic models better reflect the behavior of biological systems. Most modern approaches to plant pathology modeling require molecular kinetics information. Unfortunately, this information is not available for many plant pathogens, including <it>P. infestans</it>. Boolean formalism has compensated for the lack of kinetics; this is especially the case where comparative genomics, protein-protein interactions and differential gene expression are the most common data resources.</p

Locus for severity implicates CNS resilience in progression of multiple sclerosis

Multiple sclerosis (MS) is an autoimmune disease of the central nervous system (CNS) that results in significant neurodegeneration in the majority of those affected and is a common cause of chronic neurological disability in young adults(1,2). Here, to provide insight into the potential mechanisms involved in progression, we conducted a genome-wide association study of the age-related MS severity score in 12,584 cases and replicated our findings in a further 9,805 cases. We identified a significant association with rs10191329 in the DYSF-ZNF638 locus, the risk allele of which is associated with a shortening in the median time to requiring a walking aid of a median of 3.7 years in homozygous carriers and with increased brainstem and cortical pathology in brain tissue. We also identified suggestive association with rs149097173 in the DNM3-PIGC locus and significant heritability enrichment in CNS tissues. Mendelian randomization analyses suggested a potential protective role for higher educational attainment. In contrast to immune-driven susceptibility(3), these findings suggest a key role for CNS resilience and potentially neurocognitive reserve in determining outcome in MS

La gestión académica en pandemia : adecuaciones, innovaciones y desafíos de la Universidad Nacional de Cuyo

Este libro remite a un contexto especial e inédito que surge a partir de la pandemia de covid-19. Se trata de un contexto de alcance global signado por efectos intensos y perdurables sobre diferentes aspectos de la realidad social, económica y ambiental. En general, estos efectos provocaron, por un lado, situaciones problemáticas nuevas y, por otro lado, agravaron situaciones problemáticas preexistentes que adquirieron mayor visibilidad. En el caso argentino, las restricciones derivadas de la pandemia agudizaron la brecha socioeducativa existente y, al mismo tiempo, exigieron una gestión ágil, dinámica, resolutiva, propositiva y resiliente, especialmente a las instituciones educativas con el objeto de asegurar el derecho a la educación y su calidad. Lógicamente, la provincia de Mendoza y, por tanto, la Universidad Nacional de Cuyo (UNCUYO) no quedaron exentas de los efectos mencionados. Aunque aún no resulta posible identificar con rigor el impacto concreto que ha tenido la pandemia sobre el funcionamiento del sistema educativo provincial, se pueden entrever algunos indicadores que vale la pena atender. Por ejemplo, el egreso en la oferta de educación superior de la uncuyo registró, en 2020, una caída interanual cercana al -18 % 1. Esta oscilación se torna más relevante si se considera que este indicador se mostraba estable a lo largo de los últimos años.Fil: Castañeda, Linda.

Genome-wide Analyses Identify KIF5A as a Novel ALS Gene

To identify novel genes associated with ALS, we undertook two lines of investigation. We carried out a genome-wide association study comparing 20,806 ALS cases and 59,804 controls. Independently, we performed a rare variant burden analysis comparing 1,138 index familial ALS cases and 19,494 controls. Through both approaches, we identified kinesin family member 5A (KIF5A) as a novel gene associated with ALS. Interestingly, mutations predominantly in the N-terminal motor domain of KIF5A are causative for two neurodegenerative diseases: hereditary spastic paraplegia (SPG10) and Charcot-Marie-Tooth type 2 (CMT2). In contrast, ALS-associated mutations are primarily located at the C-terminal cargo-binding tail domain and patients harboring loss-of-function mutations displayed an extended survival relative to typical ALS cases. Taken together, these results broaden the phenotype spectrum resulting from mutations in KIF5A and strengthen the role of cytoskeletal defects in the pathogenesis of ALS.Peer reviewe

One hundred years of EEG for brain and behaviour research

On the centenary of the first human EEG recording, more than 500 experts reflect on the impact that this discovery has had on our understanding of the brain and behaviour. We document their priorities and call for collective action focusing on validity, democratization and responsibility to realize the potential of EEG in science and society over the next 100 years

The Changing Landscape for Stroke\ua0Prevention in AF: Findings From the GLORIA-AF Registry Phase 2

Background GLORIA-AF (Global Registry on Long-Term Oral Antithrombotic Treatment in Patients with Atrial Fibrillation) is a prospective, global registry program describing antithrombotic treatment patterns in patients with newly diagnosed nonvalvular atrial fibrillation at risk of stroke. Phase 2 began when dabigatran, the first non\u2013vitamin K antagonist oral anticoagulant (NOAC), became available. Objectives This study sought to describe phase 2 baseline data and compare these with the pre-NOAC era collected during phase&nbsp;1. Methods During phase 2, 15,641 consenting patients were enrolled (November 2011 to December 2014); 15,092 were eligible. This pre-specified cross-sectional analysis describes eligible patients\u2019 baseline characteristics. Atrial fibrillation&nbsp;disease characteristics, medical outcomes, and concomitant diseases and medications were collected. Data were analyzed using descriptive statistics. Results Of the total patients, 45.5% were female; median age was 71 (interquartile range: 64, 78) years. Patients were from Europe (47.1%), North America (22.5%), Asia (20.3%), Latin America (6.0%), and the Middle East/Africa (4.0%). Most had high stroke risk (CHA2DS2-VASc [Congestive heart failure, Hypertension, Age&nbsp; 6575 years, Diabetes mellitus, previous Stroke, Vascular disease, Age 65 to 74 years, Sex category] score&nbsp; 652; 86.1%); 13.9% had moderate risk (CHA2DS2-VASc&nbsp;= 1). Overall, 79.9% received oral anticoagulants, of whom 47.6% received NOAC and 32.3% vitamin K antagonists (VKA); 12.1% received antiplatelet agents; 7.8% received no antithrombotic treatment. For comparison, the proportion of phase 1 patients (of N&nbsp;= 1,063 all eligible) prescribed VKA was 32.8%, acetylsalicylic acid 41.7%, and no therapy 20.2%. In Europe in phase 2, treatment with NOAC was more common than VKA (52.3% and 37.8%, respectively); 6.0% of patients received antiplatelet treatment; and 3.8% received no antithrombotic treatment. In North America, 52.1%, 26.2%, and 14.0% of patients received NOAC, VKA, and antiplatelet drugs, respectively; 7.5% received no antithrombotic treatment. NOAC use was less common in Asia (27.7%), where 27.5% of patients received VKA, 25.0% antiplatelet drugs, and 19.8% no antithrombotic treatment. Conclusions The baseline data from GLORIA-AF phase 2 demonstrate that in newly diagnosed nonvalvular atrial fibrillation patients, NOAC have been highly adopted into practice, becoming more frequently prescribed than VKA in&nbsp;Europe and North America. Worldwide, however, a large proportion of patients remain undertreated, particularly in&nbsp;Asia&nbsp;and North America.
