The Brazilian (FRANCO) method for dental age estimation: Willems' model revisited.

OBJECTIVES: This study aimed (I) to test the Willems' dental age estimation method in different geographic samples of the Brazilian population, and (II) to propose a new model combining the geographic samples in a single reference table of Brazilian maturity scores. MATERIALS AND METHODS: The sample consisted of 5017 panoramic radiographs of Brazilian males (n = 2443) and females (n = 2574) between 6 and 15.99 years (mean age = 10.99 ± 2.76 years). The radiographs were collected from the Southeastern (SE) (n = 2920), Central-Western (CW) (n = 1176), and Southern (SO) (n = 921) geographic regions. Demirjian's technique was applied followed by Willems' method and the proposed Brazilian model. RESULTS: Willems' method led to mean absolute errors (MAE) of 0.79 and 0.81 years for males and females, respectively. Root mean squared errors (RMSE) were 1.01 and 1.03 years, respectively. The Brazilian model led to MAE of 0.72 and 0.74 years for males and females, respectively, and RMSE of 0.93 years for both sexes. The MAE was reduced in 70% of the age categories. Differences between regions were statistically (p < 0.05) but not clinically significant. CONCLUSION: The new model based on a combined population had an enhanced performance compared to Willems' model and led to reference outcomes for Brazilians. CLINICAL RELEVANCE: Assessing patients' biological development by means of dental analysis is relevant to plan orthopedic treatments and follow up. Having a combined-region statistic model for dental age estimation of Brazilian children contributes to optimal age estimation practices.

On the forensic relevance of tattoos: distinguishing black inks with energy dispersive spectroscopy and backscattered scanning electron microscopy.

PURPOSE: This study aimed to analyze black tattoo inks by means of energy dispersive spectroscopy and backscattered scanning electron microscopy. METHODS: The sample consisted of five types of commercial tattoo pigments of the black colour (Easy Glow™, Electric Ink™, Iron Works™, Master Ink™, and Viper™). An Energy Dispersive Spectroscopy (EDS) detector (Silicon Drift Detector - SDD - type) attached to a Scanning Electron Microscope (SEM) device (Tescan Vega3 LMU, Libusina, Czech Republic) was used. X-ray characteristic signs were detected for each tattoo ink in an interval between 0 and 2.5 keV. The electron acceleration potential in the microscope was 15 keV. Two regions were analyzed for each sample (n = 10). On each region, a micrography of backscattered electrons (BSE) was obtained. Means and standard deviations (SD) of the weight percentages (Wt%) were calculated. RESULTS: C and O were predominant, with a mean O/C ratio between 2.69 and 2.74 Wt%. Electric Ink and Master Ink were the most similar pigments, while Easy Glow was the most distinctive - with agglomerates of Al that had a concentration 25 × higher than other specimens. Other compounds detected in the sample were Cl and Cu. CONCLUSION: EDS and SEM were efficient to distinguish black tattoo inks. These are our preliminary outcomes on the use of EDS and SEM to analyze black tattoo inks. Thus, careful interpretation is necessary to avoid rash applications in human identification practice.

Reproduction technologies in pig farming: artificial insemination - literature review / Tecnologias de reprodução na suinocultura: inseminação artificial - revisão de literatura / Tecnologías de reproducción en la porcicultura: inseminación artificial - revisión de literatura

This summary addresses the use of reproduction technologies in swine farming, with an emphasis on artificial insemination (AI). Brazilian swine farming has been growing significantly and seeks new technologies to achieve high productive indices sustainably and competitively. Pigs present favorable characteristics such as high prolificacy, fertility, rapid growth, feed efficiency, and carcass yield, which has led to intensive development of the activity with advanced genetic selection. AI is widely employed to disseminate genetic material among different regions and farms. Several AI techniques are used in modern swine farming: intrauterine insemination (IUI) allows semen deposition in the uterine region, reducing costs; fixed-time insemination (FTAI) synchronizes estrus in various females, facilitating management and increasing efficiency; deep intrauterine insemination (DIUI) deposits semen in the uterine horns, obtaining better results; and cervical insemination (CI), a traditional technique widely used, although it may be more time-consuming and present higher reflux rates. The success of AI is related to knowledge of the reproductive cycle of sows, proper nutrition, and genetic and environmental factors. Semen quality is essential, requiring collection by trained professionals and evaluation of sperm motility and morphology. Although it is a consolidated technique, there are issues to be further explored to optimize its application, defining the exact moment for insemination, reducing reflux, and adopting effective protocols. AI is an essential tool for the growth of Brazilian swine farming, but it requires continuous studies to maximize its efficiency and results, considering the farm's production goal and the size of the enterprise to achieve high reproductive and productive indices.

Este resumo aborda o uso de tecnologias de reprodução na suinocultura, com ênfase na inseminação artificial (IA). A suinocultura brasileira vem crescendo significativamente e busca novas tecnologias para alcançar altos índices produtivos de maneira sustentável e competitiva. Os suínos apresentam características favoráveis, como alta prolificidade, fertilidade, rápido crescimento, eficiência alimentar e rendimento de carcaça, o que levou ao desenvolvimento intensivo da atividade com seleção genética avançada. A IA é amplamente empregada para disseminar material genético entre diferentes regiões e granjas. Diversas técnicas de IA são utilizadas na suinocultura moderna: a inseminação intrauterina (IAIU) permite a deposição do sêmen na região uterina, reduzindo custos; a inseminação em tempo fixo (IATF) sincroniza o estro em várias fêmeas, facilitando o manejo e aumentando a eficiência; a inseminação intrauterina profunda (IAUP) deposita o sêmen nos cornos uterinos, obtendo melhores resultados; e a inseminação cervical (IAC), técnica tradicional amplamente utilizada, embora possa ser mais demorada e apresentar maiores taxas de refluxo. O sucesso da IA estar relacionado ao conhecimento do ciclo reprodutivo das matrizes, à nutrição adequada e aos fatores genéticos e ambientais. A qualidade do sêmen é essencial, exigindo coleta por profissionais treinados e avaliação da motilidade e morfologia dos espermatozoides. Apesar de ser uma técnica consolidada, há questões a serem aprofundadas para otimizar sua aplicação, definindo o momento exato para a realização da inseminação, a redução do refluxo e adoção de protocolos eficazes. A IA é uma ferramenta essencial para o crescimento da suinocultura brasileira, mas requer estudos contínuos para maximizar sua eficiência e resultados, considerando o objetivo produtivo da granja e o tamanho do empreendimento para alcançar altos índices reprodutivos e produtivos.

Chromosomal Study on Selected Small Araneomorph Spiders from Brazil, Including the First Records in Palpimanidae and Theridiosomatidae (Araneae, Araneomorphae).

Among the 50,474 spider species, only 849 have chromosomal data available in the literature. Fifty spider families remain unknown from a cytogenetic perspective. The aim of this study was to analyze chromosomally selected araneomorph spiders from Brazil, to contribute to the cytotaxonomy and chromosome evolution of this group. The karyotypes of 12 species belonging to families Corinnidae, Linyphiidae, Oonopidae, Palpimanidae, Theridiidae, Theridiosomatidae, Trachelidae, and Zodariidae were analyzed, including the first chromosomal record for the first two families. Specimens (with the abdomen content partially exposed by perforation) were subjected to colchicine, hypotonization, and fixation. In most cases, the total content of the abdomen was used to prepare slides by spreading of cell suspension and subsequent Giemsa staining. The results were as follows: Cinetomorpha simplex Simon, 1892 (Oonopidae) 2n♂ = 9, X0; Neotrops sp. and Neoxyphinus termitophilus (Oonopidae), 2n♂ = 7, X0; Otiothops birabeni (Palpimanidae); Agyneta sp. (Linyphiidae), 2n♂ = 24, X1X20; Coleosoma floridanum, Thymoites sp.1 and Thymoites sp.2 (Theridiidae), 2n♂ = 22, X1X20; Naatlo sp. (Theridiosomatidae), 2n♂ = 30, X1X20; Orthobula sp. (Trachelidae) 2n♂ = 21, X0; Falconina sp. (Corinnidae), 2n♂ = 28, X1X20; Epicratinus sp. (Zodariidae) 2n♂ = 42, X1X20. The chromosomal morphology was determined for all the samples except for Oonopidae. Most species exhibited telocentric chromosomes, with the exception of Palpimanidae and Theridiosomatidae. The main findings: 1) support an hypothesis on ancestral karyotype of Zodariidae and Oonopidae; 2) reveal a relatively high chromosome number in Palpimanidae that supports an idea on relatively high ancestral chromosome number (2n♂ = 42) of entelegyne spiders (Palpimanoidea is sister group of entelegyne spiders); 3) show that the karyotype found in Theridiosomatidae is exceptional within the Araneoidea.

Psiconeurodontologia, (bio)decodificação dental e os mil e um nomes para o charlatanismo odontológico no século XXI: uma revisão de escopo / Psychoneurodontology, dental (bio)decoding and a thousand terms for odontological charlatanism in the 21st century: a scoping review

Junto às tecnologias que surgem para aprimorar a Odontologia mundial, emergem temáticas que progressivamente prosperam no obscuro e na incerteza. Tais "áreas odontológicas" se caracterizam por uma roupagem prolixa e de alto apelo público (como por meio de inferências sobre o emocional e os mistérios do corpo humano). Em tempos de disseminação da psiconeurodontologia e (bio)decodificação dental, assim como da incerteza acerca de sua confiabilidade, faz-se imperativa a busca pela fundamentação científica que sustenta esta temática. Para isto, foi realizada uma revisão de escopo seguindo as recomendações do PRISMA-ScR e JBI. Uma ampla busca foi realizada em cinco bases de dados e em parte da literatura cinza. Não houve restrição quanto ao ano de publicação e nem quanto ao idioma. Os dados foram coletados e expostos na forma narrativa/descritiva. De maneira complementar, utilizou-se a ferramenta JBI para avaliação da qualidade metodológica. A busca resultou em 4.785 registros iniciais, dos quais somente dois foram classificados como elegíveis. Ambos os estudos foram detectados a partir da literatura cinzenta e consistiam em trabalhos peruanos de conclusão de curso em nível de graduação (Bacharelado) em Odontologia. Os trabalhos aferiam a ocorrência de lesão de cárie em quadrantes de dentes permanentes e decíduos e correlacionavam com um questionário psicoemocional. Os dois trabalhos concluíram em prol da aplicação da psiconeurodontologia e da (bio)decodificação dental como ferramentas adicionais ao armamentário diagnóstico do Cirurgião-dentista. Detectou-se alto risco de viés, em especial acerca das limitações metodológicas dos estudos elegíveis. Tendo em vista os métodos e resultados observados nos estudos elegíveis, pode-se concluir que não há fundamentação científica na psiconeurodontologia ou na (bio)decodificação dental, muito menos validade e confiabilidade para a sua aplicação na prática clínica odontológica atual

Along with the technologies that emerged to improve Dentistry worldwide, there are themes that progressively dive into darkness and uncertainty. Such "dental areas" are characterized by a verbose approach and strong public appeal (such as through inferences about the emotions and mysteries of the human body). In times of dissemination of psychoneurodontology and dental (bio)decoding, as well as uncertainty about their reliability, the search for alleged scientific foundations that support this theme is imperative. To this end, a scoping review was carried out following the recommendations of PRISMA-ScR and JBI. A broad search was carried out in five databases and part of the gray literature. There was no restriction on the year of publication or language. Data were collected and presented in narrative/descriptive form. Complementarily, the JBI tool was used to assess methodological quality. The search resulted in 4.785 initial records, of which only two were classified as eligible. Both studies were detected from the gray literature and consisted of Peruvian studies at Bachelor's degree in Dentistry. The studies measured the occurrence of caries lesions in quadrants of permanent and deciduous teeth and correlated them with a psychoemotional questionnaire. The two studies concluded in favor of the application of psychoneurodontology and dental (bio)decoding as additional tools to the dental surgeon's diagnostic armamentarium. A high risk of bias was detected, especially regarding the methodological limitations of the eligible studies. Considering the methods and results observed in the eligible studies, it can be concluded that there is no scientific basis in psychoneurodontology or dental (bio)decoding, as well as lack of validity and reliability for its application in current clinical dental practice

Dietary lipid sources for growing rabbits: A review on animal health and productivity / Fontes lipídicas na dieta de coelhos em crescimento: uma revisão sobre a saúde e a produtividade animal

Abstract Studies that explore the use of lipids and their effects on animal nutrition have become increasingly abundant, producing a mass of information. The review was carried out on a parity basis through a survey of articles in the bibliographic databases: Web of Science and Periodicals Capes, using search terms associated or not, in the plural or singular, in English and Portuguese, such as: "lipids" AND "rabbits" AND "nutrition". After analyzing the files in the two scientific databases, certain files were excluded because they did not fit the theme or because they did not meet the inclusion criteria and repeated articles. A relevance test was carried out for the use of the articles, where they should deal with the subject: articles that report the use of lipids in the nutrition of non-ruminant animals; articles made available in complete form; articles that had at least one of the keywords; articles where the main subject is related to lipids. The articles were selected and tabulated in an Excel® spreadsheet with relevant information for exploration in the review. The use of oils and fats is a favorable point in the nutrition of non-ruminant animals, presenting benefits in the enrichment of final products such as: providing higher levels of omega-3 and omega-6, and thus obtaining meat products with lower levels of saturated fat and higher unsaturated fat contents promoting benefits to human health through its consumption, reduction of food costs, improvement in palatability and appearance of foods. These are nutritional strategies used in hot seasons of the year due to the low calorific increment produced.

Resumo Estudos que exploram o uso de lipídios e seus efeitos na nutrição animal têm se tornado cada vez mais abundantes, produzindo uma grande quantidade de informações. A revisão foi realizada de forma paritária por meio de uma pesquisa de artigos nas bases bibliográficas: Web of Science e Periódicos Capes, utilizando termos de busca associados ou não, no plural ou no singular, em inglês e português, tais como: "lipídios" E "coelhos" E "nutrição". Após analisar os arquivos nas duas bases científicas, determinados arquivos foram excluídos porque não se adequavam ao tema ou não atendiam aos critérios de inclusão, além de artigos repetidos. Um teste de relevância foi realizado para a seleção dos artigos, nos quais eles deveriam tratar do assunto: artigos que relatam o uso de lipídios na nutrição de animais não-ruminantes; artigos disponibilizados na forma completa; artigos que possuíam pelo menos uma das palavras-chave; artigos nos quais o assunto principal está relacionado a lipídios. Os artigos foram selecionados e tabulados em uma planilha do Excel® com informações relevantes para exploração na revisão. O uso de óleos e gorduras é um ponto favorável na nutrição de animais não-ruminantes, apresentando benefícios no enriquecimento de produtos finais, tais como: fornecer níveis mais altos de ômega-3 e ômega-6, e assim obter produtos de carne com menores teores de gordura saturada e maiores teores de gordura insaturada, promovendo benefícios para a saúde humana por meio do consumo, redução dos custos alimentares, melhoria na palatabilidade e aparência dos alimentos. Essas são estratégias nutricionais usadas nas estações quentes do ano devido ao baixo incremento calórico produzido.

O "novo normal" na atividade física e saúde: pandemias e uberização? / The 'new normal' in physical activity and health: pandemics and uberization? / La 'nueva normalidad' en la actividad física y la salud: ¿pandemias y uberización?

Resumo A atividade física tem relevante lugar na agenda da Saúde Pública e foi muito acionada durante a pandemia da Covid-19. Com o objetivo de discutir o "novo normal" na atividade física e saúde, por meio de texto em caráter ensaístico, são abordadas a existência de duas pandemias - a de inatividade física e a de Covid-19 - e a perspectiva de ocorrer o processo de uberização. Ampliar a prática de atividade física é necessário, mas com cautela sobre o discurso da vida ativa, acima e apesar de tudo. Já a uberização, se confirmada, possivelmente terá repercussões negativas para o trabalhador, profissional/professor de Educação Física, e não garantirá a ampliação referida. Por fim, o "novo normal", localizado temporalmente com elementos analíticos até junho de 2020, reforça a necessidade de redução de iniquidades com o objetivo de ampliar possibilidades de construção de modos de vida saudável nos quais a atividade física estará incluída.

Abstract Physical activity plays a relevant role in the Public Health agenda and was often resorted to during the Covid-19 pandemic. This essay discusses the 'new normal' in physical activity and health, the existence of two pandemics - physical inactivity and Covid-19 - and the perspective of the uberization process. The practice of physical activities must be expanded but with caution about the discourse on having an active life above and despite everything. On the other hand, uberization, if confirmed, will probably cause negative impacts on workers and Physical Education professionals/teachers without guaranteeing that expansion. Finally, the 'new normal,' analytically situated until June 2020, reinforces the need to reduce health inequalities in order to expand possibilities for building healthy lifestyles in which physical activity will be included.

Resumen La actividad física ocupa un lugar relevante en la agenda de la Salud Pública y ha sido muy mencionada durante la pandemia de Covid-19. Con el objetivo de discutir la 'nueva normalidad' en la actividad física y la salud, este ensayo aborda la existencia de dos pandemias, la de inactividad física y la de Covid-19, y la posibilidad de que ocurra un proceso de uberización. Es necesario expandir la práctica de actividad física, pero con cautela en lo que se refiere al discurso de la vida activa por encima y a pesar de todo. En cuanto a la uberización, si se confirma, posiblemente tendrá repercusiones negativas para el trabajador, profesional/profesor de Educación Física, y no garantizará la expansión mencionada. Finalmente, la 'nueva normalidad', ubicada temporalmente con elementos analíticos hasta junio de 2020, refuerza la necesidad de reducir las inequidades para poder ampliar las posibilidades de construir estilos de vida saludables en los que la actividad física esté incluida.

Discursos de instituições de saúde brasileiras sobre atividade física no início da pandemia de COVID-19 / Discourses of Brazilian health institutions on physical activity at the beginning of the COVID-19 pandemic

Este estudo objetiva analisar os discursos produzidos por instituições de saúde sobre atividade física no início da pandemia de COVID-19 (março e começo de abril) no Brasil. Foi realizado um estudo documental a partir de sites de instituições de saúde, com o aporte teórico-metodológico inspirado nos estudos foucaultianos a partir do entrelaçamento da noção de discurso e seu impacto no governo das condutas. Foram compiladas 17 comunicações, sendo três de instituições governamentais, nove de sociedades médicas e cinco da educação física. Os primeiros comunicados abordaram a higiene pessoal e de equipamentos, referentes a locais fechados e em seguida a restrição de atividade física em tais espaços, indicando o domicílio para a realização das práticas. Assim, houve predomínio da atividade física em sua vertente biológica especialmente na estimativa de afetar a função imunológica. Problematizamos os discursos a partir da noção do governo das condutas, onde indivíduos e famílias foram acionados a praticar atividade física em casa, sem garantia de instrumentalização e acesso ao conhecimento e profissionais desta área

The aim of this article is to analyze discourses produced by health institutions regarding physical activity in the beginning of the COVID-19 pandemic (March and early April) in Brazil. A documentary study was carried out using websites of health institutions. The process were theoretical-methodological support inspired in Foucault's studies based on the intertwining notion of discourse and its impact on the conduct of the government. A total of 17 documents were compiled, three from government institutions, nine from medical societies and five from physical education institutions. The first documents addressed the personal and equipment hygiene concerning closed places, the following communications were about restricting physical activities in these places, finally recommending the performance of these activities at home. Therefore, physical activity predominated in its biological perspective, especially affecting immune function. The problematization of the discourses was carried out based on the governmentality notion in which individuals and families were triggered to practice physical activities at home without instrumentalization, access to knowledge and to physical education professionals

Influence of fennel in Japanese quail diet over egg quality and behavior aspects / Influência da erva-doce na dieta de codornas japonesas sobre a qualidade dos ovos e aspectos comportamentais

The objective of this research was to evaluate the effect of Pimpinella anisum (fennel) on the performance, stress, and quality of Japanese Quail eggs in the second laying cycle (73 to 77 weeks). One hundred sixty-eight female quails from Japanese sub-species (Coturnix coturnix japonica) at 73 weeks of age, divided and submitted to four treatments (0; 250; 500 and 750mg of fennel/kg of feed) were used in a randomized block design. (RBD), with seven replications and six birds per experimental plot, totaling 28 plots. Performance, behavioral, and egg quality parameters were evaluated. Bird performance was not influenced (p>0.05) by the treatments tested. The highest egg weight and albumen weight were found in birds fed 750 mg of fennel, while a higher albumen height was observed for the estimated dose of 669 mg (p<0,05). The estimated doses of 554.09 mg, 634.10 mg, and 613.10 mg of fennel were efficient in reducing agitated behaviors by riding, pecking, and stirring, respectively. However, non-aggressive variables were not influenced by the addition of fennel to the diet (p>0.05). The tonic immobility test had a decreasing linear effect (p<0.05), which indicates a lower time in seconds in tonic immobility to birds receiving 750 mg of fennel. Fennel added to the diet did not interfere with performance, but it influenced essential parameters related to egg quality and was able to alter characteristics related to bird behavior.(AU)

O objetivo desta pesquisa foi avaliar o efeito da Pimpinella anisum(erva-doce) sobre o desempenho, estresse e qualidade dos ovos de codornas japonesas no segundo ciclo de postura (73 a 77 semanas). Foram utilizadas 168 codornas fêmeas da subespécie japonesa (Coturnix coturnix japonica) com 73 semanas de idade, divididas e submetidas a quatro tratamentos (0; 250; 500 e 750mg de erva-doce/kg de ração), em delineamento em blocos casualizados (DBC), com sete repetições e seis aves por parcela experimental, totalizando 28 parcelas. Foram avaliados os parâmetros de desempenho, comportamentais e qualidade dos ovos. O desempenho das aves não foi influenciado (p>0,05) pelos tratamentos testados. O maior peso dos ovos e peso do albúmen foram encontrados nas aves alimentadas com 750 mg de erva-doce, enquanto a maior altura do albúmen foi observada pela dose estimada de 669 mg (p<0.05). As variáveis comportamentais agressivas foram consideradas diferentes entre os níveis analisados (p<0,05). As doses estimadas de 554,09 mg, 634,10 mg e 613,10 mg de erva-doce foram eficientes na redução dos comportamentos agitados montando, bicando e agitada, respectivamente. No entanto as variáveis não agressivas não foram influenciadas pela adição de erva-doce na dieta (p>0,05). O Teste de imobilidade tônica teve efeito linear (p<0,05) decrescente, que indica um menor tempo em segundos em imobilidade tônica para as aves que receberam 750 mg de erva-doce. A erva-doce adicionada à dieta não interfere no desempenho, porém melhorou à qualidade dos ovos e foi capaz de alterar características relacionadas ao comportamento das aves.(AU)

Soft tissue thickness in Brazilian adults of different skeletal classes and facial types: A cone beam CT - Study.

The aim in this study was to evaluate the influence of skeletal class, facial type, and sex on soft tissue thickness (STT) of the craniofacial midline in a Brazilian subpopulation. Thus, 121 cone beam computed tomography (CBCT) scans (54 males and 67 females, age 21 to 40 yrs) composed the study sample. Patients were classified according to skeletal class (class I, II, and III) and facial type (brachycephalic, mesocephalic, and dolichocephalic), and STT was measured (mm) in 10 landmarks in the craniofacial midline for each CBCT scan. Multivariate analysis of covariance evaluated facial STT with regard to multiple independent variables (sex, age - covariate, facial type, and skeletal class). TEM and rTEM assessed the intra-examiner agreement. STT was significantly greater in males than in females for all regions measured (p < 0.05), except for the pogonion-pogonion' landmark (p>0.05). In general, class III individuals had significantly thicker soft tissue in the maxilla - subspinale-subnasale', prosthion-labrale superius', and incision-stomion' regions, while class II subjects had thicker soft tissue in the infradentale-labrale inferius' mandibular landmark (p < 0.05). Regarding facial type, dolichocephalic individuals showed significantly thicker soft tissue in the supramentale-supramentale' mandibular landmark, whereas brachycephalic subjects had thicker soft tissue in maxillary regions - prosthion-labrale superius' and incision-stomion' (p < 0.05). rTEM values were below 5% for most landmarks, and all TEM values were below 1 mm.

The Highest Chromosome Number and First Chromosome Fluorescent in situ Hybridization in the velvet worms of the family Peripatidae.

The diversity of Onychophora is poorly studied, despite there being nearly 200 described species divided in two families: Peripatidae and Peripatopsidae. Peripatid velvet worms are found mainly in the Neotropical region. The low morphological diversity in Peripatidae is an obstacle to determining its taxonomy, and chromosomal analyses can help clarify this. The aim of this work was to chromosomally analyze one species of Epiperipatus from Mato Grosso do Sul, Brazil. Conventional staining and telomeric fluorescent in situ hybridization (FISH) were performed with the gonads of three males of Epiperipatus sp. The specimens showed 2n♂ = 73, the largest diploid number found in Onychophora to date, with the majority of chromosomes acro/telocentrics and the largest element submetacentric. The FISH marked the telomeric region of all elements and revealed one Interstitial Telomeric Site (ITS) on the proximal region of the long arm large submetacentric chromosome. The absence of male meiosis and female cell division in the analyzed specimens prevented us from determining whether the unpaired large submetacentric is a sex chromosome, which could lead to the description of a rare sex chromosome system (SCS) in Onychophora, or a case of fusion between autosomes. In either case, the presence of ITS is a clear indication of chromosomal fusion.

Influence of fennel in Japanese quail diet over egg quality and behavior aspects / Influência da erva-doce na dieta de codornas japonesas sobre a qualidade dos ovos e aspectos comportamentais

The objective of this research was to evaluate the effect of Pimpinella anisum (fennel) on the performance, stress, and quality of Japanese Quail eggs in the second laying cycle (73 to 77 weeks). One hundred sixty-eight female quails from Japanese sub-species (Coturnix coturnix japonica) at 73 weeks of age, divided and submitted to four treatments (0; 250; 500 and 750mg of fennel/kg of feed) were used in a randomized block design. (RBD), with seven replications and six birds per experimental plot, totaling 28 plots. Performance, behavioral, and egg quality parameters were evaluated. Bird performance was not influenced (p>0.05) by the treatments tested. The highest egg weight and albumen weight were found in birds fed 750 mg of fennel, while a higher albumen height was observed for the estimated dose of 669 mg (p0.05). The tonic immobility test had a decreasing linear effect (p<0.05), which indicates a lower time in seconds in tonic immobility to birds receiving 750 mg of fennel. Fennel added to the diet did not interfere with performance, but it influenced essential parameters related to egg quality and was able to alter characteristics related to bird behavior.

O objetivo desta pesquisa foi avaliar o efeito da Pimpinella anisum(erva-doce) sobre o desempenho, estresse e qualidade dos ovos de codornas japonesas no segundo ciclo de postura (73 a 77 semanas). Foram utilizadas 168 codornas fêmeas da subespécie japonesa (Coturnix coturnix japonica) com 73 semanas de idade, divididas e submetidas a quatro tratamentos (0; 250; 500 e 750mg de erva-doce/kg de ração), em delineamento em blocos casualizados (DBC), com sete repetições e seis aves por parcela experimental, totalizando 28 parcelas. Foram avaliados os parâmetros de desempenho, comportamentais e qualidade dos ovos. O desempenho das aves não foi influenciado (p>0,05) pelos tratamentos testados. O maior peso dos ovos e peso do albúmen foram encontrados nas aves alimentadas com 750 mg de erva-doce, enquanto a maior altura do albúmen foi observada pela dose estimada de 669 mg (p0,05). O Teste de imobilidade tônica teve efeito linear (p<0,05) decrescente, que indica um menor tempo em segundos em imobilidade tônica para as aves que receberam 750 mg de erva-doce. A erva-doce adicionada à dieta não interfere no desempenho, porém melhorou à qualidade dos ovos e foi capaz de alterar características relacionadas ao comportamento das aves.

Egg quality of laying hens fed diets with plant extracts

The objective of this study was to evaluate the effect of marigold flower extract and paprika on egg quality of Black Avifran laying hens in different periods of storage. A completely randomized design study with a 3x3 factorial scheme with three diets (control, paprika, and marigold flower extract) and three storage periods (0, 7, and 14 days) was carried out. The following metrics were evaluated: egg weight, yolk weight, shell weight; yolk color, albumen height, specific gravity, and Haugh unit as well as the yolk, shell, and albumen percentage relative to the total weight of the egg. There was no significant interaction between additives and storage time (p > 0.05) for most of the parameters evaluated. The only exception was observed for yolk color, in which the interaction effect between treatments was significant (p < 0.05). The effect of storage time was significant (p < 0.05) for albumen weight, albumen percentage, yolk color, albumen height, specific gravity, and Haugh unit, with reduction of these parameters over the evaluation period. The use of paprika and marigold flower extract in the diets of Black Avifran laying hens does not influence egg quality.(AU)

Distillers dried grains with solubles from corn in diet of japanese quails

The objective of this study was to evaluate different inclusion levels of distillers dried grains with solubles (DDGS) from corn in the diet of quails. A total of 210 japanese quails (Coturnix coturnix japonica) were distributed in a completely randomized design of five treatments and six replicates, with seven quails per experimental unit. The treatments used were: control feed; inclusion of 5, 10, 15 and 20% of DDGS. The variables assessed were: feed intake, feed conversion per dozen and egg mass, egg production, egg weight, specific gravity, yolk color and economic analysis. Data were analyzed by regression model and Dunnetts test at 5% probability. For individual feed intake, laying rate, and feed conversion per egg mass, specific gravity and yolk color by color fan, there was effect caused by inclusion of DDGS (p < 0.05), but the other variables did not show significant difference. By Dunnetts test, for feed intake, feed conversion per egg mass, specific gravity and digital colorimeters L parameter, there was effect (p < 0.05). As for economic analysis, DDGS presented low cost. It can be concluded that DDGS can be used in feed at a 20% level without impairing the performance and quality of quails eggs.(AU)

A inclusão, a escola e a subjetivação docente: analisando o contexto do município do rio grande 1 / Inclusion, school and teaching subjectivity: analyzing the context of rio grande city

RESUMO: Há uma proliferação discursiva da inclusão como algo ético e benevolente, especialmente, nos discursos educacionais. Fundamentadas no pós-estruturalismo, notamos como os jogos de saber-poder-verdade instituem regimes discursivos que constrangem os indivíduos a agirem de determinados modos, constituindo subjetividades. Objetivamos analisar os discursos acerca da inclusão escolar e perceber como eles vêm produzindo formas de ser professor. A partir da aplicação de questionários a formandos de cursos de licenciatura e professores da Educação Básica, foi possível perceber que: a) o papel atribuído à escola, muitas vezes, se resume aos processos de socialização e à adequação física e material do espaço e; b) o papel do professor é descrito a partir do que denominamos subjetividades docentes contemporâneas, traduzidas em um sujeito docente, moral, mediador e responsável pelo sucesso/fracasso da inclusão. Assim, percebemos que esses discursos constituem subjetividades docentes contemporâneas que se curvam ao pressuposto da inclusão como um imperativo de Estado.

ABSTRACT: There is a discursive proliferation of school inclusion as something ethical and benevolent, especially in educational speeches. Based on post-structuralism, we note how the relation between knowledge-power-truth establishing discursive regimes that constrain individuals to act in certain subjective ways. Thus, we aimed to analyze the discourses about school inclusion and to understand how they have produced ways of being a teacher. The work uses the application of the questionnaires to graduates from degree courses and teachers of Basic Education. The results have revealed that: a) the role assigned to school often comes down to the socialization processes and physical and material appropriateness of space and; b) the teacher's role is described from what we call contemporary teaching subjectivity, translated into a moral teacher, mediator and responsible for the success/failure of school inclusion. Therefore, we realize that these speeches are contemporary teaching subjectivity who bow to the inclusion assumption as a State imperative.
