Orientador: José Luiz Moraes Vasconcelos / Resumo: Este trabalho foi delineado para avaliar se a inclusão de CIDR® durante 6 dias em protocolo à base de GnRH e PGF2α associado à remoção de bezerros (RB) aumenta a concepção a IATF (TCIA) em vacas Nelore paridas e se protocolos de sincronização aumentam a taxa de gestação (TG) no início da estação de monta (EM). Foram utilizadas 453 vacas Nelore multíparas entre 34 e 74 dias pós-parto (d 0). Os animais foram divididos aleatoriamente nos tratamentos: TI: RB (48h, d -10) - GnRH (Gonadorelina, 50 mcg, d -8) - PGF2α (Dinoprost Trometamina, 25mg, d -2) + RB (40h) - GnRH (Gonadorelina, 50mcg, d 0) + IATF; TII: RB (48h, d -10) - GnRH (Gonadorelina, 50mcg, d -8) + CIDR® - PGF2α (Dinoprost Trometamina, 25mg, d -2) + retirada do CIDR® + RB (40h) - GnRH (Gonadorelina, 50mcg, d 0) + IATF. Após a IATF os animais foram submetidos à monta natural (até d90). A ciclicidade foi determinada pela concentração de P4 em duas amostras de sangue (d -18 e -10). Escore de condição corporal (1 a 5, ECC) foi avaliado no dia -18. A taxa de concepção a IATF e as taxas de gestação acumulativas foram avaliadas nos dias 44, 74, 104 e 134 após a IATF. Os dados foram analisados por regressões logística e linear do SAS. O ECC interferiu (P<0,01) na TCIA de maneira diferente para os tratamentos sem e com CIDR®. Os animais com ECC entre 3,25 e 3,75 apresentaram maiores TCIA. Vacas com ECC ≤ 3,50 apresentaram melhor resposta ao TII, enquanto as vacas com ECC > 3,50 apresentaram melhor resposta ao TI. A TCIA apresentou relação inversa à taxa de ciclicidade. Os animais em anestro apresentaram melhores (P<0,01) TCIA em relação aos ciclando, 40,5 e 21,9% respectivamente. Independente do ECC e ciclicidade, a TG durante a EM foi maior nos animais sincronizados em relação ao controle, sendo de 78,7, 85,3 e 57,8% aos 90 dias para os animais sincronizados sem e com CIDR® e para o controle...

Nelore multiparous cows (n = 453), with 34 to 74 days postpartum, were divided at treatments as follows: TI: CR (48h, d -10) - GnRH (Gonadorelin 50 mcg, d -8) - PGF2α (Dinoprost Trometamina, 25 mg, d -2) + CR (40h) - GnRH (Gonadorelin 50 mcg, d 0) + TAI; TII: CR (48h, d -10) - GnRH (Gonadorelin 50 mcg, d -8) + CIDR® in - CIDR® out + PGF2α (Dinoprost Trometamina, 25 mg, d -2) + CR (40h) - GnRH (Gonadorelin 50 mcg, d 0) + TAI; TIII (control) was submitted just at natural service. After TAI the animals (TI, TII and TIII) were submitted to natural service until d 90. Cyclicity was determined by serum P4 in two blood samples (d -18 and d -10). Body condition score (BCS) was determined on day -18. Conception rate to TAI and PR were evaluated by rectal palpation 44, 74, 104 and 134 days after TAI. A logistic and linear regression model (Logistic - SAS) was used. The BCS influenced differently conception rate at TAI between treatments with or without CIDR®. The animals with intermediary BCS (3,25 to 3,75) exhibited higher conception rate at TAI. Cows with BCS 3,50 showed better results at TII, while the cows with BCS > 3,50 had better results at TI. The conception rate at TAI had inverted relation to cyclicity. The anestrous animals showed better (P<0,01) conception rate at TAI in relation to cyclic cows, 40,5 and 21,9%, respectively. Independent of BCS and cyclicity, the pregnancy rate during the breeding season was bigger in the synchronized animals (TI and TII) in relation to control (TIII) that was 78,7, 83,5 and 57,8% at 90 days of breeding season and just at this time the control group (TIII) showed...

Reproduction and milk production are considered to be the main factors influencing the whole economy of cattle breeding. We have been monitoring the worsening reproduction related to cattle breeding for a long time. The introduction of synchronization protocols into reproductive management is a posibility to improve reproduction. The aim of my work was to detect the success rate of insemination after rut synchronization on the basis of the data analysis and to evaluate reproductive indicators. The monitoring was performed from January 2017 to June 2018. There were monitored 310 breeding Holstein cows with the yield level of 10 335 kg of milk. The data were obtained from the zootechnical records and the Farmsoft Program. The breeding reproductive level was poor. Here are following values of reproductive indicators: insemination interval - 63 days, service period - 124 days, intervening time - 407 days, intersemination interval - 35 days, insemination index - 2,63 and pregnancy after the first insemination - 33,23%. That was only the insemination interval to achieve great results because breeding cows were involved into the synchronization protocol Presynch within 31 to 38 days after birth. It was detected that cows after the synchornization program Presynch got pregnant in 36,6% after the first insemination, whereas breeding cows being inseminated for the required rut became pregnant in 28% cases after the first insemination. The percentage of pregnancy in synchronizated cows after the first insemination is almost identical to the average in the Czech Republic (37,1%). Performing hormonal therapy within Presynch increased the reproductive costs in one cow by 211 Czech crowns.

Micronúcleos são estruturas constituídas por material cromatínico contido por um envoltório nuclear e menores que o núcleo principal. Apesar do amplo uso do teste do micronúcleo na avaliação do potencial genotóxico de diversas substâncias, os trabalhos cujas preocupações sejam elucidar o mecanismo de formação dessas estruturas, seu conteúdo e a fase do ciclo celular em que surgem, são raros. O objetivo do presente trabalho foi estudar a cinética de surgimento de micronúcleos em células A549, provenientes de carcinoma de pulmão humano, submetidas à sincronização. Após duplo bloqueio por ausência de soro fetal bovino e adição de vincristina ao meio, o surgimento de micronúcleos foi acompanhado com o auxílio de um marcador para fase S. Os resultados obtidos indicam que micronúcleos podem surgir tanto durante a mitose quanto na intérfase e possuem capacidade de replicação de DNA, independentemente do núcleo principal. A capacidade de escapar ao duplo bloqueio permite sugerir que o ponto de checagem de ligação ao fuso mitótico em A549 não é funcional. Também foram observadas seqüências amplificadas de EGFR no interior dos micronúcleos. A interpretação do significado dos micronúcleos é importante para a definição de sua relação com a expulsão de oncogenes em células tumorais ou de outras seqüências amplificadas. / Micronuclei are structures composed by chromatin material contained in the nuclear envelope and smaller than the main nucleus. Micronucleus test has been widely used in the genotoxic potential evaluation of different compounds. Although a few report concerning on the mechanism of micronucleus genesis, its DNA sequences content and the cell cycle phase when they arise. The aim of this work was to analyze the kinetic of micronuclei in A549 cells from human lung carcinoma submitted to cell cycle synchronization. After double blocking by fetal bovine serum deprivation and vincristine treatment, micronucleus formation was monitored with a S-phase marker. The results have showed that both in the mitosis and in the interphasic phase, micronuclei may arise and they were able to replicate its DNA. This process seemed to be independent of main nucleus. Cellular ability to escape from double blocking suggests that mitotic spindle checkpoint in A549 is not functional. Moreover, EGFR sequences were detected into the micronucleus. It is important to elucidate the micronucleus meaning to describe precisely its association with elimination of oncogene or other amplified sequences from the tumor cells.

Os sistemas de automação se tornam cada vez mais abrangentes e complexos, criando a necessidade de uma estruturação básica durante o seu desenvolvimento de forma a permitir melhor visualização, organização e entendimento destes sistemas.

At the end of this research, this method is applied in a practical case for its validation.

Os modelos metapopulacionais são uma ferramenta muito importante nos estudos de habitats fragmentados. Sendo a natureza bastante diversificada, a análise de ambientes heterogêneos e primordial para a construção de uma dinâmica mais próxima da realidade. Com isso, buscou-se construir um modelo metapopulacional heterogêneo de múltiplas espécies, cujo objetivo e encontrar um critério de estabilidade assintótica de orbitas de sincronização parcial. Para tanto e descrito um ambiente com n patches ou sítios conectados por movimentos de migração divididos em conjuntos, que apresentam diferentes características de sobrevivência e reprodução de cada espécie. Obteve-se uma representação para matriz Jacobiana do sistema, al em de um critério para o cálculo do expoente de Lyapunov. Sendo possível, então, uma generalização para um modelo metapopulacional heterogêneo de múltiplas espécies. / The metapopulational models are an important appliance in the fragmented habitats studies."The nature is very diversi ed, so the heterogeneous environments analysis is primordial for close construction of dynamics realities. Therefore, this research aimed to construct a metapopulational heterogeneous model of multiple species in order to nd an asymptotic stability standard of partial synchronization of orbits. Hence an environment with n patches or connected sites by migration movements were described, whose were divided into groups with di erent survival and reproduction characteristics of each species. A Jacobian matrix of system representation was obtained, as well as a Lyapunov exponent calculation criteria. Thus, a generalization for a heterogeneous metapopulational model of multiple species was possible.

Quatro experimentos foram realizados para avaliar as concentrações plasmáticas de progesterona ([P4]) e as taxas de fertilidade na inseminação artificial em tempo fixo (IATF) após o uso de diferentes dispositivos de liberação lenta de progesterona (DP). No primeiro experimento foram utilizadas 4 novilhas ovariectomizadas. Esses animais receberam 5 diferentes tipos de DP, nos quais se variou a superfície de contato (50cm&sup2; ou 100 cm&sup2; e a dose de progesterona (0,5g; 1,0g e 2,0g) Os dispositivos foram inseridos aos pares durante 7 dias e se estabeleceu um intervalo entre tratamentos de pelo menos 30 dias. Com os dados de [P4] 24 horas e sete dias após a inserção do DP obtiveram-se as seguintes equações de regressão, respectivamente: [P4]24h = 0,238 + 0,0343(área) + 0,513(dose); (R&sup2;=0,94) e [P4] 7d = 0,331+ 0,0056(área) + 0,329(dose); (R&sup2;=0,71). No segundo experimento foram comparados dois dos dispositivos testados no primeiro estudo: P50-1,0 (50 cm2 área; 1,0g dose P4) e P50-1,5 (50 cm&sup2; área; 1,5g dose P4) com dois dispositivos comerciais: CIDR (120 cm&sup2; área; 1,9g P4 dose) e DIB (120 cm&sup2; área; 1,0g P4 dose). Os dispositivos foram inseridos em 15 novilhas Nelore pré-puberes para avaliação das [P4] obtendo-se, após 24 horas de inserção, para CIDR, DIB, P50-1,5 e P50-1,0, respectivamente: 7,7&plusmn;2,8&ordf; ; 4,5&plusmn;0,75b; 5,9&plusmn;2,5b e 2,1&plusmn;0,5c ng/ml e após 8 dias, respectivamente: 3,3&plusmn;0,7&ordf; ; 2,6&plusmn;2,0&ordf;; 3,0&plusmn;2,4&ordf; e 1,1&plusmn;0,27bng/ml. As regressões obtidas no primeiro experimento não foram eficientes para estimar as [P4] obtidas no estudo 2. Nos experimentos 3 e 4 comparou-se a eficiência dos dispositivos DIB e P50-1,5 em 431 vacas de corte zebuínas e cruzadas, com bezerros ao pé e multíparas, após uso em um programa de IATF no qual os dispositivos permaneciam nos animais durante 8 dias; quando da colocação desses dispositivos, eram aplicados 2mg de benzoato de estradiol (BE) e, na retirada, 400UI de eCG. Uma última dose de BE foi administrada 24 horas após a retirada dos DP, e a IATF foi realizada 54 horas após a retirada dos DP. Não foram encontradas diferenças nas taxas de concepção da IATF entre dispositivos. As taxas de concepção variaram entre 30 e 51,6% nos lotes tratados. O tratamento diminuiu o intervalo tratamento-parto de 365 para 317 dias, comparado à monta natural. / Four studies have been made to evaluate the plasmatic progesterone concentration ([P4]) of different intravaginal low delivery progesterone devices (PD) and the fertility rates after their use in timed artificial insemination (TAI). In the first study there were used 4 ovariectomized heifers. These animals received 5 kinds of prototypes PD on which varied the contact surface (50 or 100 cm&sup2;) and the progesterone doses (0,5; 1,0 or 2g). These PD were inserted in the vaginas in pairs and the interval between treatments was higher than 30 days. With the data of [P4] there were found the fallowing regressive equations for the days 1 and 7 after the insertion , respectively: [P4]24h = 0,238 + 0,0343(surface) + 0,513(dose); (R&sup2;=0,94) and [P4]7d = 0,331+ 0,0056(surface) + 0,329(dose); (R&sup2;=0,71). In the second study there were compared 2 prototypes PD based on the first study: P50-1,0 (50 cm&sup2; surface; 1,0g dose P4) and P50-1,5 (50 cm&sup2; surface; 1,5g dose P4) with two commercial PD: CIDR (120 cm&sup2; surface; 1,9g P4 dose) and DIB (120 cm&sup2; surface; 1,0g P4 dose). These PD were inserted in 15 prepuberal Nelore heifers to evaluate the [P4] The [P4] (in ng/ml) found after 24 hours were for CIDR, DIB, P50-1,5 e P50-1,0, respectively: 7.7&plusmn;2.8&ordf; ; 4.5&plusmn;0.75b; 5.9&plusmn;2.5b e 2.1&plusmn;0.5c ng/ml and after 8 days, respectively: 3.3&plusmn;0.7&ordf; ; 2.6&plusmn;2.0&ordf;; 3.0&plusmn;2.4&ordf; e 1.1&plusmn;0.27b ng/ml. The regressive equations found in the first study were not efficient to estimate the [P4] for the prototypes PDs. In the studies 3 and 4 there were compared the PD DIB and P50-1.5 for TAI in 431 Nelore and cross-breed lactating postpartum beef cows. The TAI protocol was: PD insertion per 8 days, administration of 2 mg estradiol benzoate (EB) in the insertion day - 400 UI of eCG in the PD removal - 1mg EB 24 hours after PD removal- TAI 54 hours after the PD removal. There were no differences in TAI conception rates between PD. The TAI conception rates ranged from 30 to 51.6% in the treated herds. The treatment has decreased the treatment-partum interval from 365 to 317 days on animals submitted to natural mating.

"Renal autoregulation stabilizes renal blood flow to protect the glomerular capillaries and maintain glomerular filtration rates through two mechanisms: tubuloglomerular feedback (TGF) and the myogenic response (MR). It is considered that the feedback mechanisms operate independently in each nephron (the functional unit of the kidney) within a kidney, but renal autoregulation dynamics can be coupled between vascular connected nephrons. It has also been shown that the mechanisms are time-varying and interact with each other. Understanding of the significance of such complex behavior has been limited by absence of techniques capable of monitoring renal flow signals among more than 2 or 3 nephrons simultaneously. The purpose of this thesis was to develop approaches to allow the identification and characterization of spatial and temporal properties of renal autoregulation dynamics. We present evidence that laser speckle perfusion imaging (LSPI) effectively captures renal autoregulation dynamics in perfusion signals across the renal cortex of anaesthetized rats and that spatial heterogeneity of the dynamics is present and can be investigated using LSPI. Next, we present a novel approach to segment LSPI of the renal surface into phase synchronized clusters representing areas with coupled renal autoregulation dynamics. Results are shown for the MR and demonstrate that when a signal is present phase synchronized regions can be identified. We then describe an approach to identify quadratic phase coupling between the TGF and MR mechanisms in time and space. Using this approach we can identify locations across the renal surface where both mechanisms are operating cooperatively. Finally, we show how synchronization between nephrons can be investigated in relation to renal autoregulation effectiveness by comparing phase synchronization estimates from LSPI with renal autoregulation system properties estimated from renal blood flow and blood pressure measurements. Overall, we have developed approaches to 1) capture renal autoregulation dynamics across the renal surface, 2) identify regions with phase synchronized renal autoregulation dynamics, 3) quantify the presence of the TGF-MR interaction across the renal surface, and 4) determine how the above vary over time. The described tools allow for investigations of the significance and mechanisms behind the complex spatial interactions and time-varying properties of renal autoregulation dynamics. "

Neste trabalho utilizamos técnicas de controle e sincronização de sistemas caóticos, visando o uso delas para comunicação com caos. Aplicamos tais técnicas no circuito elétrico de Matsumoto-Chua. Inicialmente, mostramos a sensibilidade dos atratores deste circuito quando variamos os seus parâmetros. Determinamos as suas bacias de atração. Através da análise biespectral, verificamos que o acoplamento quadrático é alto para o atrator tipo Rössler, e quase nulo para o atrator Espiral-Dupla. Para a caracterização global do circuito, apresentamos diagramas, no espaço de parâmetros, com os valores dos expoentes de Lyapunov ou autocorrelação. A seguir estudamos esse circuito com uma perturbação senoidal. Com isto, identificamos novos cenários para a transição para o caos a partir da quase periodicidade. Duas destas transições foram identificados pela primeira vez nesse circuito. Aplicamos ao circuito cinco métodos de controle de caos: supressão de caos por sincronização de freqüências, controle de órbitas periódicas instáveis pelos métodos OGY e de realitnentação , estabilização no ponto ele equilíbrio (método de Hwang), migração e arraste (método OPCL). Finalmente, consideramos dois circuitos de Matsumo-Chua acoplados e determinamos as suas bacias de sincronização. Mostramos que a sincronização dos circuitos acoplados pode não depender das condições iniciais (fronteira das bacias contínua) ou ser extremamente sensível às condições iniciais (fronteira elas bacias elo tipo crivada ou intercrivada). / In this work we use control and synchronization of chaos techniques aiming their implementation in communicating with chaos. These techniques are applied into the electric circuit of Matsumoto-Chua. Initialty, we show the sensibility of the attractors under parameter variations. We determine the attractor basin of attractions. Through the bi-spectral analysis, we verify that the quadratic coupling is high for the Rössler-type attractor, and almost null for the Double-Scroll attractor. For the global charactcrization of this system, we show parameter diagrams of the Lyapunov exponents or auto-correlation. We also study this circuit under a sinusoidal perturbation. In this configuration, we identify new scenario for the transition to chaos through quasi-periodicity. Two of these transitions are identified by us for the first time in this perturbed circuit. We apply five control of chaos techniques: chaos suppression by frequency synchronization, control of unstable periodic orbits by the OGY and feed-back methods, stabilization of the equilibrium points (Hwang method), migration and entrainment (OPCL method). Finally, we consider two acoupled Matsumoto-Chua\'s circuits and determine their synchronization basins. We show that the synchronization in these coupled circuits may not depend on the initial conditions (continuous synchronization basin boundary) or may depend extremely on the initial conditions (riddled or intermingled synchronization basin boundaries).
