Parâmetros hematológicos e bioquímicos em três raças de cavalos de alta performance do Sul do Brasil

The hematological and biochemical parameters are useful tools for clinics and feeding management of athlete equines. The population of high performance horses consists of different breed groups, displaying specific phenotypic and metabolic characteristics related to the type of sport activity they perform. In the state of Rio Grande do Sul, in the South of Brazil, racing, jumping, polo, endurance, reigning, and dressage are the main activities. This study investigated the hemato-biochemical parameters in three high performance horse breeds from Southern Brazil. A total number of 154 horses belonging to the breeds Thoroughbred, Brasileiro de Hipismo, and Criollo, were selected for this study. Within each breed, samples were collected from males (n=12) and non-pregnant females (n=12) of two ages: 1 to 3 years of age (n=12) and over five years of age (n=12). Hematological (total count of erythrocytes and leukocytes, blood cell volume, hemoglobin, and differential count of leukocytes) and biochemical (lactate, fructosamine, glucose, cholesterol, total protein, albumin, globulins, fibrinogen, urea, calcium, magnesium, phosphorus, and enzymes LDH, AST, GGT, and CK) parameters were analyzed. Significant differences were observed in hematological and biochemical parameters, except for calcium and albumin, among breeds. There was no significant effect of age or sex within breed. This study shows that the local population, the breed and the type of sport activity are important variables to be considered in the analysis of blood parameters of horses.Os parâmetros hematológicos e bioquímicos são ferramentas que auxiliam na clínica e no manejo alimentar do eqüino atleta. Na população eqüina de alta performance existem diferentes grupos raciais que apresentam características fenotípicas e metabólicas específicas, relacionadas com o tipo de atividade esportiva que exercem. Atualmente, no Rio Grande do Sul (Sul do Brasil), são reconhecidas as modalidades esportivas de corrida, salto, polo, enduro, provas de rédeas e provas funcionais. O presente trabalho estudou os parâmetros hemato-bioquímicos em três raças de eqüinos de alta performance no Sul do Brasil. Um total de 154 animais das raças Puro Sangue Inglês, Brasileiro de Hipismo e Crioula foram selecionados para este estudo. Em cada grupo racial foram obtidas amostras de machos (n=12) e fêmeas não gestantes (n=12) e de duas faixas etárias: de 1 a 3 anos (n=12) e de mais de cinco anos (n=12). Foram analisados parâmetros hematológicos (contagem total de eritrócitos e leucócitos, hematócrito, hemoglobina e contagem diferencial de leucócitos) e bioquímicos (lactato, fructosamina, glicose, colesterol, proteína total, albumina, globulinas, fibrinogênio, uréia, cálcio, magnésio, fósforo e enzimas LDH, AST, GGT e CK). Foram observadas diferenças significativas nos parâmetros hematológicos e bioquímicos, exceto para cálcio e albumina, entre os grupos raciais. Não houve efeito significativo da idade e do sexo dentro da mesma raça. O presente trabalho mostra que o fator racial e o tipo de atividade esportiva são variáveis importantes que devem ser consideradas na análise de parâmetros sangüíneos em eqüinos

Role of dynamical particle-vibration coupling in reconciliation of the d3/2d_{3/2} puzzle for spherical proton emitters

It has been observed that decay rate for proton emission from $d_{3/2}$ single particle state is systematically quenched compared with the prediction of a one dimensional potential model although the same model successfully accounts for measured decay rates from $s_{1/2}$ and $h_{11/2}$ states. We reconcile this discrepancy by solving coupled-channels equations, taking into account couplings between the proton motion and vibrational excitations of a daughter nucleus. We apply the formalism to proton emitting nuclei $^{160,161}$Re to show that there is a certain range of parameter set of the excitation energy and the dynamical deformation parameter for the quadrupole phonon excitation which reproduces simultaneously the experimental decay rates from the 2$d_{3/2}$, 3$s_{1/2}$ and 1$h_{11/2}$ states in these nuclei.Comment: RevTex, 12 pages, 4 eps figure

Theoretical description of deformed proton emitters: nonadiabatic coupled-channel method

The newly developed nonadiabatic method based on the coupled-channel Schroedinger equation with Gamow states is used to study the phenomenon of proton radioactivity. The new method, adopting the weak coupling regime of the particle-plus-rotor model, allows for the inclusion of excitations in the daughter nucleus. This can lead to rather different predictions for lifetimes and branching ratios as compared to the standard adiabatic approximation corresponding to the strong coupling scheme. Calculations are performed for several experimentally seen, non-spherical nuclei beyond the proton dripline. By comparing theory and experiment, we are able to characterize the angular momentum content of the observed narrow resonance.Comment: 12 pages including 10 figure

In-pandemic development of an application ontology for COVID-19 surveillance in a primary care sentinel network

Background: Creating an ontology for coronavirus disease 2019 (COVID-19) surveillance should help ensure transparency and consistency. Ontologies formalise conceptualisations at either domain or application level. Application ontologies cross domains and are specified through testable use cases. Our use case was extension of the role of the Oxford Royal College of General Practitioners (RCGP) Research and Surveillance Centre (RSC) to monitor the current pandemic and become an in-pandemic research platform. Objective: To develop an application ontology for COVID-19 which can be deployed across the various use case domains of the Oxford- RCGP RSC research and surveillance activities. Methods: We described our domain-specific use case. The actor was the RCGP RSC sentinel network; the system the course of the COVID-19 pandemic; the outcomes the spread and effect of mitigation measures. We used our established three-step method to develop the ontology, separating ontological concept development from code mapping and data extract validation. We developed a coding system–independent COVID-19 case identification algorithm. As there were no gold standard pandemic surveillance ontologies, we conducted a rapid Delphi consensus exercise through the International Medical Informatics Association (IMIA) Primary Health Care Informatics working group and extended networks. Results: Our use case domains included primary care, public health, virology, clinical research and clinical informatics. Our ontology supported: (1) Case identification, microbiological sampling and health outcomes at both an individual practice and national level; (2) Feedback through a dashboard; (3) A national observatory, (4) Regular updates for Public Health England, and (5) Transformation of the sentinel network to be a trial platform. We have identified a total of 8,627 people with a definite COVID-19 status, 4,240 with probable, and 59,147 people with possible COVID-19, within the RCGP RSC network (N=5,056,075). Conclusions: The underpinning structure of our ontological approach has coped with multiple clinical coding challenges. At a time when there is uncertainty about international comparisons, clarity about the basis on which case definitions and outcomes are made from routine data is essential

MEtop - a generator for single top production via FCNC interactions

We present a generator for single top quark production via flavour-changing neutral currents. The MEtop event generator allows for Next-to-Leading-Order direct top production $pp \to t$ and Leading-Order production of several other single top processes. A few packages with definite sets of dimension six operators are available. We discuss how to improve the bounds on the effective operators and how well new physics can be probed with each set of independent dimension six operators.Comment: 26 pages, 22 figure
