Detection of bovine herpesvirus 5 (BoHV-5) in formalin-fixed, paraffin-embedded bovine brain by nested PCR in Colombian cattle

Fifteen cases of viral meningoencephalitis in Colombian cattle were tested by nested PCR analysis for the detection of bovine herpesvirus 5 (BoHV-5). All fatal cases had shown severe neurological signs and had occurred following natural outbreaks of the disease. The neurological infection was histologically characterized by mild to moderate inflammatory changes in the brain and cerebellum, including meningitis, mononuclear perivascular cuffing, gliosis, haemorrhage, and the presence of Gitter cells (macrophages) accompanying large areas of malacia. No intranuclear inclusion bodies were seen in any of the cases. Results from BoHV-5 molecular extraction analyses showed there were five positive cases thus confirming the presence of the virus in Colombia.

Abordaje práctico sobre cómo mejorar el bienestar en los bovinos

Current challenges of humanity require a new paradigm for animal production, and invest time and attention to the development of new production techniques that take into account the principles of sustainability and animal welfare science. To do this, we must be committed to promoting animal welfare and health, ensure environmental sustainability, consumer satisfaction and profitability for producers. To change our relationship with animals there is no need for changes in market conditions or large investments, it is enough to know better the needs of the animals we raise, the management system adapted to its characteristics. Even in the most favorable management conditions, on farms that have technological resources and trained personnel, there is much to change, especially in the daily management of the animals. Some of the risks more evident in the traditional systems of beef production are: problems during parturition, morbidity and mortality of calves, lack of shade in the pastures, improper handling of animals, risk of injury, inadequate infrastructure, poor management practices during routine processing (marking, castration, vaccination, dehorning), poor welfare during loading, transport, unloading and slaughter. To remedy this, you can adopt good management practices, which have been shown to reduce risk and improve the welfare of cattle in different stages of the production chain. The objective of this review is to show some of the risks that reduce the welfare of cattle and examples of how the adoption of best management practices impact on improving the productivity of these production systems. Finally, some indicators for assessing welfare in production systems are shown.

Veredas infinitas, Recepção italiana de Grandes sertões: veredas

L'obiettivo principale di questo lavoro è valutare le difficoltà di comprensione e di identificazione nella ricezione da parte della cultura italiana dell'opera Grande sertão: veredas, da quelle trovate, in modo pionieristico, dal traduttore italiano, a quelle che sono state percepite e indicate al momento della lettura dai critici, dagli accademici, dall'autore di questo lavoro e, soprattutto, dai lettori comuni, mostrando, allo stesso tempo, che i problemi avuti dagli italiani nella traduzione esistono, sotto certi aspetti, anche per i brasiliani urbani, poiché la dimensione linguistico-geografica presente nel romanzo è così peculiare, che perfino molti lettori di lingua portoghese ignorano il mondo plasmato dal linguaggio di Guimarães Rosa rivelando una esacerbazione della questione universale espressa nella formula "traduttori, traditori". Partendo da tutto ciò, abbiamo cercato di dimostrare che, sebbene la traduzione di Edoardo Bizzarri abbia raggiunto un eccellente risultato, l'opera rosiana, così come nella poesia e di più di qualsiasi altra narrativa, comporta, nel passaggio da un idioma all'altro, perdite irrimediabili, tanto relative all'armonia musicale e ritmica, quanto alla richezza semantica che si occulta nel testo originale

Estudo sistemático de estrelas variáveis na era dos grandes surveys

The interest in the systematic analysis of astronomical time series data, as well as development in astronomical instrumentation and automation over the past two decades has given rise to several questions of how to analyze and synthesize the growing amount of data. These data have led to many discoveries in the areas of modern astronomy asteroseismology, exoplanets and stellar evolution. However, treatment methods and data analysis have failed to follow the development of the instruments themselves, although much effort has been done. In present thesis, we propose new methods of data analysis and two catalogs of the variable stars that allowed the study of rotational modulation and stellar variability. Were analyzed the photometric databases fromtwo distinctmissions: CoRoT (Convection Rotation and planetary Transits) and WFCAM (Wide Field Camera). Furthermore the present work describes several methods for the analysis of photometric data besides propose and refine selection techniques of data using indices of variability. Preliminary results show that variability indices have an efficiency greater than the indices most often used in the literature. An efficient selection of variable stars is essential to improve the efficiency of all subsequent steps. Fromthese analyses were obtained two catalogs; first, fromtheWFCAMdatabase we achieve a catalog with 319 variable stars observed in the photometric bands Y ZJHK. These stars show periods ranging between ∼ 0, 2 to ∼ 560 days whose the variability signatures present RR-Lyrae, Cepheids , LPVs, cataclysmic variables, among many others. Second, from the CoRoT database we selected 4, 206 stars with typical signatures of rotationalmodulation, using a supervised process. These stars show periods ranging between ∼ 0, 33 to ∼ 92 days, amplitude variability between ∼ 0, 001 to ∼ 0, 5 mag, color index (J - H) between ∼ 0, 0 to ∼ 1, 4 mag and spectral type CoRoT FGKM. The WFCAM variable stars catalog is being used to compose a database of light curves to be used as template in an automatic classifier for variable stars observed by the project VVV (Visible and Infrared Survey Telescope for Astronomy) moreover it are a fundamental start point to study different scientific cases. For example, a set of 12 young stars who are in a star formation region and the study of RR Lyrae-whose properties are not well established in the infrared. Based on CoRoT results we were able to show, for the first time, the rotational modulation evolution for an wide homogeneous sample of field stars. The results are inagreement with those expected by the stellar evolution theory. Furthermore, we identified 4 solar-type stars ( with color indices, spectral type, luminosity class and rotation period close to the Sun) besides 400 M-giant stars that we have a special interest to forthcoming studies. From the solar-type stars we can describe the future and past of the Sun while properties of M-stars are not well known. Our results allow concluded that there is a high dependence of the color-period diagram with the reddening in which increase the uncertainties of the age-period realized by previous works using CoRoT data. This thesis provides a large data-set for different scientific works, such as; magnetic activity, cataclysmic variables, brown dwarfs, RR-Lyrae, solar analogous, giant stars, among others. For instance, these data will allow us to study the relationship of magnetic activitywith stellar evolution. Besides these aspects, this thesis presents an improved classification for a significant number of stars in the CoRoT database and introduces a new set of tools that can be used to improve the entire process of the photometric databases analysis

Efeitos da administração subaracnóidea de grandes volumes de lidocaína a 2% e ropivacaína a 1% sobre a medula espinhal e as meninges: estudo experimental em cães

JUSTIFICATIVA E OBJETIVOS: A injeção de grandes volumes de anestésico local no espaço subaracnóideo, após punção dural acidental, é complicação da anestesia peridural. O objetivo desta pesquisa foi investigar as possíveis alterações clínicas e histológicas desencadeadas por grandes volumes de lidocaína a 2% e ropivacaína a 1%, simulando injeção subaracnóidea acidental, em cães. MÉTODO: Vinte e um cães foram distribuídos aleatoriamente em 3 grupos, que receberam por via subaracnóidea: G1 - cloreto de sódio a 0,9%; G2 - lidocaína a 2% e G3 - ropivacaína a 1%. A punção subaracnóidea foi realizada no espaço intervertebral L6-L7. O volume de anestésico local administrado foi de 1 ml para cada 10 cm de distância entre a protuberância occipital e o espaço lombossacral (5 - 6,6 ml). Após 72 horas de observação clínica os animais foram sacrificados e foi removida a porção lombossacral da medula para exame histológico, por microscopia óptica. RESULTADOS: Nenhum animal do G1 apresentou alterações clínicas ou histológicas da medula espinhal. Foram observados dois casos de necrose do tecido nervoso em G2, porém mudanças clínicas, em somente um desses cães e em outros dois animais que não apresentaram alterações histológicas. Foi encontrada necrose focal do tecido nervoso medular em um animal de G3. Todos os animais de G3 permaneceram clinicamente normais. CONCLUSÕES: Conclui-se que grandes volumes de lidocaína a 2% determinaram alterações clínicas e histológicas mais intensas que os de ropivacaína a 1%.
