Genetic diversity in wild (Sus scrofa scrofa) and domestic (Sus scrofa domestica) pigs and their hybrids based on polymorphism of a fragment of the D-loop region in the mitochondrial DNA

We examined the variation in mitochondrial DNA by sequencing the D-loop region in wild and domestic (large-white breed) pigs, in hybrids between domestic and wild pigs, and in Monteiro pigs. A D-loop fragment of approximately 330 bp was amplified by PCR. Sequencing of DNA amplicons identified haplotypes previously described as European and Asian types. Monteiro pigs and wild pigs had European haplotypes and domestic pigs had both European and Asian haplotypes. ©FUNPEC-RP.

Ultrastructural morphology and morphometry of the normal corneal endothelium of adult crossbred pig

O endotélio corneal é uma monocamada de células poligonais. A integridade e saúde dessa camada são essenciais para a manutenção da transparência corneal normal. Este estudo reportou pela primeira vez, de forma detalhada, a morfologia ultra-estrutural e a morfometria do endotélio corneal de suínos adultos mestiços à microscopia eletrônica de varredura (MEV). A superfície endothelial corneal apresentou um padrão regular de células poligonais, com predomínio da forma hexagonal e de bordas celulares nítidas. O núcleo foi observado como protuberância arredondada no centro da célula. Também foram observados os cílios (2-4) em apenas algumas células da região periférica da córnea, as aberturas das vesículas pinocitóticas na proximidade dos cílios, as microvilosidades, as varas da borda e as bordas celulares em formato de zigzag. A área celular média foi significativamente maior (P<0,05) no centro da córnea do que na periferia, com um coeficiente de variação menor no centro da córnea. A densidade celular média foi significativamente maior na periferia (P<0,05) e 43,9% maior que os dados reportados por outros autores na microscopia especular, o que demonstra o efeito da retração celular durante o processamento das amostras. O valor médio do número de lados das células (pleomorfismo) foi de 5,9, o que evidencia um predomínio do formato hexagonal. A percentagem de células hexagonais foi significativamente maior no centro (P<0,001). Os parâmetros obtidos nesta pesquisa servirão de base para estudos futuros sobre o efeito de medicamentos, cirurgias intracamerulares ou soluções para armazenamento de córneas para transplantes no endotélio corneal do suíno.

Use of near-infrared Raman spectroscopy to detect IgG and IgM antibodies against Toxoplasma gondii in serum samples of domestic cats

Near-infrared Raman spectroscopy (NIRS) is a particularly promising technique that is being used in recent years for many biomedical applications. Optical spectroscopy has gained increasing prominence as a tool for quantitative analysis of biological samples, clinical diagnostic, concentration measurements of blood metabolites and therapeutic drugs, and analysis of the chemical composition of human tissues. Toxoplasmosis is an important zoonosis in public health, and domestic cats are the most important transmitters of the disease. This disease can be detected by several serological tests, which usually have a high cost and require a long time. The goal of this work was to investigate a new method to diagnosis Toxoplasma gondii infections using NIRS. In order to confirm antibody detection, 24 cat blood scrum samples were analyzed by the Raman spectra, from which 23 presented positive serology to toxoplasmosis and one was a reference negative serum. Characteristic Raman peaks allowed differentiation between negative and positive sera, confirming the possibility of antibody detection by Raman spectroscopy. These results give the first evidence that this technique can be useful to quantify antibodies in cat sera.

Effect of adding macro and micro minerals in pig feces fed diets with different levels of probiotic

O objetivo deste trabalho foi avaliar dietas contendo diferentes doses (0, 100, 200 e 300 ppm) de probiótico sobre a produção diária de fezes (PDF) e teor de macro e microminerais nas fezes de suínos, nas fases de creche e de crescimento e no período total. A PDF, como porcentagem do peso vivo, somente apresentou diferença estatística (P<0,05) na fase inicial 1. Os teores de macro e microminerais excretados nas fezes não apresentaram diferença (P>0,05) entre tratamentos, a exceção de cálcio e sódio na fase inicial 1 e cálcio, zinco e níquel no período total. A adição de um poliprobiótico às dietas, não afetou a produção de fezes dos suínos nas fases de creche e de crescimento. Entretanto, a presença de microrganismos, adicionados (níveis de 200 e 300 ppm) às dietas reduziu a excreção fecal de cálcio, zinco e níquel.

Genetic relatedness among wild, domestic and Brazilian fighting roosters

Except for the meat- and egg-type strains used in commercial poultry farms in Brazil, there are no scientific reports about the origin of birds from the genus Gallus that have been introduced in this country with domestication or fighting purposes. Therefore, the aim of this study was to identify the position of the Brazilian Game Bird in the phylogenetic tree of the genus Gallus by nucleotide sequence analysis of the mitochondrial DNA D-loop region. The results indicate that fighting roosters comprise two different clusters within the species Gallus gallus domesticus. One of the clusters is related to the wild ancestors, while the other one is more related to the birds raised by the poultry industry. In conclusion, Brazilian fighting roosters have originated from the red jungle fowl (Gallus gallus) and belong to the subspecies Gallus gallus domesticus.

An overview of domestic aspects in US climate policy

The article shows how domestic aspects influence the United States national and international climate policy. To accomplish the task, the authors analyzes the discussions when Bill Clinton was ruling the country, a time during which global discussions were forwarded. The paper recalls the debate in the Bush administration and the growing polarization since Barack Obama took office.

The Impact of Domestic Politics and International Changes on the Brazilian Perception of Regional Integration

This article aims to analyze the impact of domestic politics and international changes that influence Brazilian positions regarding regional integration processes in South America, particularly the Southern Common Market, Mercosur. The dynamics of the international system and their impact on the evolution of the elite's perception of the role the country should play in the world are important variables for understanding these positions. The state's postures in relation to integration were and are based on a real interest, but this interest is also linked with the objective of ensuring better conditions for participation in other international arenas. Starting with the hypothesis that transformations in the international setting have strongly influenced Brazil's positioning, the elements of continuity and change in the country's behavior toward Mercosur are identified, with domestic politics as the main explanation.

Giving up reporting the aggressor: reports of female victims of domestic violence

The goal of this study is to describe the experience of female victims of domestic violence, who forfeited the lawsuits against their aggressors. The interviews were oriented by the question: What was your experience of forfeiting the denunciation of your aggressor? Three themes emerged from the convergence of the testimonies: time passed from the aggression to the denunciation and then to the forfeiting; the partner, the family, the women's precinct; reflecting about the experience, which described the studied phenomenon. The women expressed ambiguous feelings for their aggressor: affection, anger, humiliation and fear. They recognize that they are dominated and humiliated, but notions of justice and equality between spouses do not appear in the testimonies. Forfeiting can be understood in the context of the reproduction of the traditional family structure, conditioned to economic and social factors. Results highlight implications about the role of the Women's Precinct and the healthcare institutions in the care for women who were victims of domestic violence.
