Chronic Mild Stress (CMS) is an experimental model for depression: Rats are submitted to a set of stressing conditions and as a result their consumption of water and water with sucrose, as well as the animals previous preference for water and water and sucrose also drops. It is argued that the stress changes the organism and, consequently, changes the reinforcing properties of water and water with sucrose. Therefore the stress would make the subjects insensible to reward. The present study investigated if what has been called sensitivity to reward could be described as a drop in the reinforcing value of a reinforcer. In other words, one of this study's goals was to evaluate if a protocol of mild stress diminished the reinforcing value of a known reinforcer, here, water with sucrose. Four male rats were submitted to a stress protocol of six weeks (as described by Willner, Towell, Sampson, Sophokleus e Muscat (1987). Two of them were also submitted to operant sessions of a FR-FR concurrent schedule of reinforcement, with responses followed either by water or water with sucrose prior and after the stress protocol. Results showed that all four subjects diminished their overall liquid consumption while the stress protocol was in effect. Results also showed the two subjects preferred water with sucrose on the FRFR condition (with higher rates of responses on the lever associated with water with sucrose), and that these subjects recovered their overall consumption and their preference for water with sucrose faster than the two subjects not submitted to the operant condition
Chronic Mild Stress (CMS) é um modelo animal experimental proposto como um modelo de depressão, ao qual ratos são submetidos. Após passarem por um conjunto de "situações de estresse suave", o consumo de água e de água com sacarose desses animais decresce. Considera-se que a submissão ao conjunto de estressores modifica o organismo e, consequentemente, a propriedade recompensadora da água e da água com sacarose. Supõe-se, então, que o sujeito toma-se "Insensível" à recompensa. O presente estudo pretendeu replicar os resultados de Willner, Towell, Sampson, Sopholeus e Muscat (1987) e também verificar se o que é denominado "Insensibilidade à recompensa" poderia ser descrito como diminuição do valor reforçador do estímulo, uma vez que este estímulo, nos estudos de CMS, não é produzido sistematicamente por uma ação/resposta dos sujeitos sistematicamente medida. Ou seja, a submissão ao "regime de estresse" afetaria o valor reforçador do estímulo? Ratos machos foram sujeitos. Dois sujeitos foram submetidos a um conjunto de condições de estresse suave, por 6 semanas, conforme descritos por Willner e cols. (1987), como por exemplo, privação de água e comida, barulho intermitente, iluminação contínua, agrupamento de dois sujeitos na mesma gaiola, luz estroboscópica, cheiro, apresentação de uma garrafa vazia após privação de água, acesso restrito a comida, inclinação da gaiola, presença de um objeto estranho na gaiola e chão da gaiola sujo. Verificou-se uma diminuição no consumo total de líquido e na preferência por água com sacarose destes sujeitos durante e após este procedimento. Outros dois sujeitos foram submetidos a sessões operantes sob um esquema concorrente FR15-FRI5 com água e água com sacarose como estímulos reforçadores antes e após a submissão ao mesmo conjunto de estressores. Também com estes sujeitos observou-se diminuição no consumo de líquido e na preferência por água com sacarose em testes semanais de consumo de líquido, durante as semanas de exposição ao estresse, o que indicaria um aparente efeito do regime de estresse sobre o valor reforçador dos estímulos. Observou-se também, com estes sujeitos, que a submissão à condição operante após o período de estresse parece ter alterado o efeito produzido pelo CMS, aumentando o consumo de líquido e a preferência pela água com sacarose nos testes realizados nas semanas seguintes à exposição ao regime de estresse

Chronic Mild Stress (SMS) is an anhedonia experimental animal model, induced by the chronic exposition of rats to a mild stressors protocol, and measured by the intake of sucrose, intracranial stimulation and/or site preference conditioning. Aside from anhedonia, this model is also recognized by the production of losses in the body weight, independently of specific feeding regimes and other characteristics analogous to the conditions that compose the depression diagnosis. The objective of the present study was to investigate if the exposition of the subjects to a water VT concurrent scheme water with sucrose 8% VT, of same value, before and after the stressors protocol, would produce disturbances: (1) in the body weight of the subjects; (2) in the diary consumption of food and water; (3) in the consumption and preference of liquids; (4) in the time during which the subjects remained close to the stimulus water and to the stimulus water with sucrose in the operant conditioning box, and (5) in the time in which the subjects have emitted responses in the site of the water fountain and of the water with sucrose 8% fountain. The design was composed by three experimental conditions: (1) exposition of the subjects VTP3, VTP4, VTP7, VTP8, P5, P6, P13 and P15 to the stressors protocol; (2) submission of the subjects VTP3, VTP4, VTP7 and VTP8 to the concurrent 20s VT sessions and (3) application of consumption and liquids´ preference tests in all of the experimental subjects, including the subject C10. The main disturbances noticed were: (a) decrease in the weight losses during the exposition to the protocol and decrease in weight variations during the role experiment; (b) diary water consumption similar to the ones of the subjects submitted to the FR and VI sessions; (c) increase in the diary food consumption, mainly during the exposition to the protocol; (d) constant consumption and preference by sucrose; (e) preference by sucrose in the 20s VT sessions after the exposition to the protocol, and (f) increase in the subjects´ general activity along the submission to the 20s VT sessions. The subjects exposed only to the protocol and to the liquid consumption tests didn´t present decrease in the sensibility to the reinforcer stimulus water with sucrose, what is commonly observed in other studies
Chronic Mild Stress (CMS) é um modelo animal experimental de anedonia, induzida através da exposição crônica de ratos a um protocolo de estressores pouco severos, e medida a partir de ingestão de sacarose, estimulação intracraniana e/ou condicionamento de preferência de lugar. Além de anedonia, este modelo também é reconhecido por produzir perda de peso corporal, independente de regime alimentar específico, e outras características análogas ao que compõe o diagnóstico de depressão. O objetivo do presente estudo foi investigar se a exposição de sujeitos a um esquema concorrente VT água VT água com sacarose a 8%, de mesmo valor, antes e após o protocolo de estressores, produzia alterações: (1) no peso corporal dos sujeitos; (2) no consumo diário de ração e água; (3) no consumo e preferência de líquidos; (4) no tempo em que os sujeitos permaneceram do lado do estímulo água ou do estímulo água com sacarose na caixa de condicionamento operante, e (5) no tempo em que os sujeitos emitiram respostas na região do bebedouro água ou do bebedouro água com sacarose a 8%. O delineamento foi composto por três condições experimentais: (1) exposição dos sujeitos VTP3, VTP4, VTP7, VTP8, P5, P6, P13 e P15 ao protocolo de estressores; (2) submissão dos sujeitos VTP3, VTP4, VTP7 e VTP8 as sessões concorrentes VT 20s e (3) aplicação dos testes de consumo e preferência de líquidos a todos os sujeitos da pesquisa, incluindo o sujeito C10. As principais alterações observadas foram: (a) menor diminuição de peso durante a exposição ao protocolo e menor variação de peso durante todo o experimento (b) consumo diário de água semelhante aos dos sujeitos submetidos às sessões de FR e VI; (c) aumento no consumo diário de ração, principalmente durante a exposição ao protocolo; (d) consumo de líquidos e preferência por sacarose constantes; (e) preferência por sacarose nas sessões VT 20s após a exposição dos sujeitos ao protocolo, e (f) aumento da atividade geral dos sujeitos ao longo da submissão às sessões VT 20s. Os sujeitos expostos somente ao protocolo e aos testes de consumo de líquido não apresentaram diminuição de sensibilidade ao estímulo reforçador água com sacarose comumente observado nos outros estudos

Chronic Mild Stress (CMS) an experimental animal model of anhedonia induced by exposing the rats to a protocol of chronic stress for a long period of time. At the Laboratório do Programa de Pós Graduação em Psicologia Experimental: Análise do Comportamento, a research line about CMS and its relation with the operant behavior has been developed since 2001, as in Pereira (2009). Unlike other studies conducted in this laboratory, Pereira (2009) did not observe sucrose intake and preference reducing (anhedonia) along stressors. One pointed hypothesis was the neonatal handling was a responsible variable for that. The goal of this study was to investigate whether the neonatal handling alters the fluid intake and preference on rats that were submitted to the stressors protocol (CMS) during the adult phase. Three groups were divided among experimental conditions: 1) neonatal handling, 2) protocol and 3) neonatal handling and protocol. The used measures were: weight, ration and water intake and weekly tests over intake and fluid preference. Results found show that stressors protocol reduced weight of subjects from the manipulation group (MP) as for the ones from only stressors protocol group (P). Food and water intake also presented similar results for Groups P and MP: all subjects presented water intake enhance and ration intake reducing during protocol. For fluid intake and preference tests, both Group P and MP presented preference oscillation at no stressors period and sucrose intake enhance during protocol submission weeks, that means, they did not produced anhedonia. Results allow to assure that the group submitted to maternal manipulation with 15min mother s separation did not show any difference in comparison to the nohandling group, specially related to preference and intake tests, when submitted to CMS

Diferente de outros estudos realizados nesse laboratório, Pereira (2009) não observou redução da ingestão e preferência de sacarose (anedonia) durante os estressores. Uma das hipóteses levantadas foi que a manipulação neonatal tenha sido uma variável responsável por isso. O objetivo do presente estudo foi investigar se a manipulação neonatal, altera a ingestão e preferência de líquidos em ratos que passaram pelo protocolo de estressores (CMS) durante a fase adulta. Três grupos foram divididos entre as condições experimentais: 1) manipulação neonatal, 2) protocolo e 3) manipulação neonatal e protocolo. As medidas utilizadas foram: peso, consumo de ração e de água e testes semanais de ingestão e preferência de líquido. Os resultados encontrados mostram que o protocolo de estressores diminuiu o peso dos sujeitos tanto para o grupo que passou pela manipulação (MP) quanto para o que passou apenas pelo protocolo de estressores (P). O consumo de alimento e água também apresentou resultados semelhantes para os Grupos P e MP: todos apresentaram aumento na ingestão de água e diminuição do consumo de ração durante o protocolo. Para os testes de consumo e preferência de líquido, tanto o Grupo P quanto o MP apresentaram oscilação de preferência no período sem estressores e aumento da ingestão de sacarose durante as semanas de submissão ao protocolo, ou seja, não produziram anedonia. Os resultados permitem afirmar que o grupo que passou pelo procedimento de manipulação neonatal separados da mãe por 15min não apresentou diferença em comparação com o grupo que não foi manipulado, principalmente em relação aos testes de ingestão e preferência, quando submetidos ao CMS

Full textA measurement of the production of a Z boson in association with two or more photons is presented. The analysis is based on proton proton collisions data collected by the CMS experiment, at a centre of mass energy of 13 TeV, and corresponding to an integrated luminosity of about 137 inverse femtobarns. Events are reconstructed in a fiducial phase space by selecting pairs of same flavour opposite sign leptons, originating from the Z boson decay, and at least two isolated photons. The background contributions to this process are divided into two classes, "prompt" and "non-prompt", the former including events with genuine photons while the latter representing events where one or more reconstructed photons originate from hadrons decay inside jets. The non-prompt background source is estimated with a data-driven technique, while the prompt background source is estimated by using simulated events. The measured fiducial cross section is in agreement with the Standard Model prediction and the observed significance corresponds to 4.8 standard deviations. Events selected in the same phase space used for the fiducial cross section measurement are also exploited to set limits on several anomalous Quartic Gauge Couplings, in terms of dimension 8 effective field theory operators. The constraints obtained are compatible and complementary to other studies which use alternative production and decay channels. This work represents the first study of the associated production of Z boson and at least two photons at a centre of mass energy of 13 TeV.

Chronic Mild Stress (CMS) is an experimental animal model of induced anhedonia by exposing rats to a protocol of mild stressors for a long period of time. This model is an attempt to reproduce in controlled environment conditions analogous to the real environment, seen as important to produce behavioral changes. To identify other effects of exposure to CMS, this study aimed to verify whether the exposure to chronic mild stress produces changes in the establishment of a simple discrimination after the expouse to the protocol. Therefore, the subjects of this study had their weight and food and water intake measured daily, tests of consumption and preference of liquid were realized weekly; subjects were exposed to the protocol stressors over six weeks and, after this period was initiated the discriminative training. The experiment consisted of four experimental conditions: (1) one subject was exposed, like all other subjects, to tests of consumption and preference of liquids, (2) four subjects were exposed to the protocol, (3) four subjects were exposed to the protocol and to a discrimination procedure(4) four subjects were exposed only to the discrimination procedure and they weren t exposoused to the chronic mild stress. The results obtained in this study indicate that: (a) subjects exposed to the protocol showed a greater loss and variation of the body weight; (b) during the protocol the average of water consumption increased and average food consumption decreased for subjects exposed to the protocol. (c) tests of consumption and preference of liquids did not show a reduction in preference for the sucrose subtance but an increase in the total fluid intake for subjects exposed to stress. And, finally, (d) observed that exposure protocol stressors interfere with the acquisition of a simple discrimination. For subjects exposed to the protocol were required, on average, twice as many sessions to reach the criterion of two consecutive sessions with discriminative indices above 80%. and (e) that the subjects exposed to the protocol showed differences in tests of generalization when compared with subjects exposed only to discrimination. And, lastly (d) observed that exposure to the protocol interfered the acquisition of a simple discrimination. The subjects exposed to the protocol required, on average, twice as many sessions to reach the criterion of two consecutive sessions with discriminative indices above 80% and (e) the subjects exposed to the protocol showed differences in the generalization tests when compared with subjects exposed only to discrimination.Thereby, the exposure to a condition of chronic mild stress and affects the acquisition of a simple discrimination established after the protocol. This result may indicate that exposure to stress condition altered the reinforcing value of the stimulus for the subjects who were exposed to it, this change may have been responsible for the differences obtained in the discrimination of subjects exposed to this condition and subjects who were not exposed to the protocol
O Chronic Mils Stress (CMS) é um modelo animal experimental de anedonia induzida através da exposição de ratos a um protocolo de estressores crônicos e moderados por um longo período de tempo. Este modelo é uma tentativa de reproduzir, em ambiente controlado, condições análogas às do ambiente real, vistas como importantes para a produção de alterações comportamentais. Visando identificar outros efeitos da exposição ao CMS, o presente estudo teve como objetivo verificar se a exposição a eventos aversivos crônicos e moderados produz alterações no estabelecimento de uma discriminação simples posterior ao protocolo de estressores. Para tanto, os sujeitos do presente estudo tiveram o peso e o consumo de ração aferidos diariamente; foram expostos a testes semanais de consumo e preferência de líquidos; foram expostos ao protocolo de estressores ao longo de seis semanas e, após o encerramento deste, foi iniciado o treino discriminativo. O delineamento foi composto por quatro condições experimentais: (1) um sujeito foi exposto, como todos os outros sujeitos, aos testes de consumo e preferência de líquidos, (2) quatro sujeitos foram expostos ao protocolo de estressores, (3) quatro sujeitos foram expostos ao protocolo de estressores e a discriminação simples e (4) quatro sujeitos foram expostos a uma discriminação simples sem exposição aos estímulos crônicos e moderados. Os resultados obtidos no presente estudo indicam que: (a)os sujeitos expostos ao protocolo de estressores apresentaram uma maior perda e variação no peso corporal; (b) durante o protocolo o consumo médio de água aumentou e o consumo médio de ração diminuiu para os sujeitos expostos ao protocolo. (c) nos testes de consumo e preferência de líquidos não foi observado uma redução na preferência por sacarose e sim um aumento no consumo total de líquidos para os sujeitos expostos a condição de estresse. E, por fim, (d) observou-se que a exposição ao protocolo de estressores interferiu na aquisição de uma discriminação simples. Para os sujeitos expostos ao protocolo foram necessárias, em média, o dobro de sessões para atingir o critério de duas sessões consecutivas com índices discriminativos superiores a 80% e (e) que os sujeitos expostos ao protocolo apresentaram diferenças nos testes de generalização se comparados com os sujeitos expostos somente à discriminação. Assim, é possível concluir que a exposição a uma condição de estresse crônica e moderada afeta a aquisição de uma discriminação simples posteriormente estabelecida. Esse resultado pode indicar que a exposição à condição de estresse alterou o valor reforçador do estímulo para os sujeitos que foram expostos a ele, essa alteração pode ter sido responsável pelas diferenças obtidas na discriminação dos sujeitos expostos a essa condição e dos sujeitos que não foram expostos aos estressores

Full textNeste trabalho investigamos a produção e detecção de novas ressonâncias de uma extensão do Modelo Padrão, o modelo 331, no detector CMS. Este modelo prediz que o número de famílias de férmions seja múltiplo de número de cor dos quarks e apresenta como assinaturas características a existência de novos bósons como o Z' e os bi-léptons duplamente carregados. Concentramos na busca destas ressonâncias de alta massa decaindo em di-múons, no caso do Z', e no canal de 2 múons e 2 elétrons para os estudos sobre os bi-léptons. O método de verossimilhança foi utilizado para quantificar a probabilidade da descoberta do Z', que possui como fundo irredutível o processo Drell Yan. Estudamos também a produção de bi-léptons que são uma assinatura única deste modelo.
In this work, we study the production and detection of the new resonances of an extension of Standard Model, the 331 model, in the CMS detector. This model predicts that the number of fermion families to be a multiple of the number of quark colors and it has as special signatures new bosons, the Z' and the double charged bi-leptons. In the Z' boson analysis, we search it through modification in the mass spectrum of highmass dimuons pairs and for the double charged bi-leptons search in the 2 muons and 2 electrons decay channel. The potential discovery of Z' boson was estimated using the Likelihood Method where the Drell-Yan process is the main background. The bi-leptons are an exclusive signature of model, which was used to discriminate this model.

Na Organização Europeia para a Pesquisa Nuclear (CERN), o Large Hadron Collider (LHC) colide grupos de prótons 40 milhões de vezes por segundo a uma energia de 13 TeV. Operando junto ao LHC, o Compact Muon Solenoid (CMS) é um detector projetado para identificar uma ampla gama de partículas produzidas nessas colisões. As partículas produzidas em cada colisão são observadas nos subdetectores na busca de pistas sobre a Natureza no seu nível mais fundamental. Apesar do modelo padrão das partículas elementares ter sido testado em uma variedade de experimentos de altas energias, um dos principais objetivos do LHC é a busca de uma nova física além daquela prevista pela teoria existente. Nesse trabalho analisamos os dados de colisões próton-próton produzidos pelo LHC operando com energia de centro de massa de 13 TeV e coletados pelo CMS em 2015. O presente estudo envolve a busca de uma ressonância X não observada previamente, decaindo em um par de bósons vetoriais. Os resultados são interpretados no contexto do modelo de dimensões extras deformadas de Randall-Sundrum, distinguindo as hipóteses de fundo (modelo padrão) e fundo mais sinal (modelo padrão + graviton). Nenhuma evidência da existência de uma partícula com as características do graviton de Randall-Sundrum foi encontrada.
At the European Organization for Nuclear Research (CERN), the Large Hadron Collider (LHC) smashes groups of protons 40 million times per second at an energy of 13 TeV. Operating at the LHC, the Compact Muon Solenoid (CMS) is a multipurpose detector conceived to identify a large variety of particles produced in such collisions. The produced particles are observed at the sub-detectors in search of clues about Nature at the most fundamental level. In spite of the impressive agreement of the standard model with all the experimental results obtained so far, one of the main aims of the LHC is the search of new physics beyond the one foreseen by this theoretical model. In this work, we analyze proton–proton collisions delivered by the LHC operating at centre-of-mass energy of 13 TeV and collected by CMS during 2015. The channel under study involves the search for an unknown resonance X decaying into a pair of vector bosons. The results are interpreted in the context of the Randall-Sundrum warped extra-dimensional model, distinguishing between the hypotheses of background only (standard model) and background plus signal (standard model + graviton). No evidence of the existence of a graviton-like particle was found.
