Pesquisa de células neoplásicas em medula óssea de cadelas com tumor de mama /

Corsini, Talita Beani. January 2019 (has links)
Orientador: Rosemeri de Oliveira Vasconcelos / Resumo: A glândula mamária é o segundo sítio mais comum de desenvolvimento tumoral em cadelas. Uma das formas de estadiamento destes tumores é avaliar a presença ou ausência de metástase à distância, inclusive na medula óssea. Este achado, na Medicina, associa-se a baixa sobrevida de mulheres com tumores mamários, porém na Medicina Veterinária esse estadiamento clínico é mais utilizado para pacientes com linfomas e mastocitomas. Estudos que utilizem a biópsia de medula óssea como método de pesquisa de estadiamento em tumores mamários são escassos. Desta forma o presente estudo teve como objetivo avaliar lesões mamárias e a medula óssea de 36 cadelas, buscando-se células tumorais disseminadas ou focos metastáticos. Para isso realizou-se a análise histopatológica dos tumores de mama, linfonodos e medula óssea dessas cadelas, corados com Hematoxilina e Eosina. Na medula óssea também foram utilizadas a coloração com Tricrômio de Masson, para avaliação de fibrose medular, e a imunohistoquímica, para a pesquisa de micrometástase. O carcinoma em tumor misto grau I fora o mais observado (18,08%), não havendo diferença estatística com relação ao tamanho tumoral e a presença de metástase em linfonodos. Na medula óssea de uma cadela com carcinossarcoma (4,35%) houve marcação citoplasmática de uma provável célula tumoral disseminada, de origem epitelial, com o anticorpo citoqueratina-19 pela imunohistoquímica. Nenhuma das cadelas que apresentou diminuição da celularidade ou fibrose medular (Tric... (Resumo completo, clicar acesso eletrônico abaixo) / Mestre

Evaluation of Endotracheal Tube Cuff Pressure and The Use of Three Cuff Inflation Syringe Devices in Dogs

Wan-Chu Hung (6612920) 15 May 2019 (has links)
<p>Over-inflation of an endotracheal tube (ETT) cuff may lead to tracheal necrosis, whereas under- inflation increases the risk of pulmonary aspiration. The objectives of this 2-phase study were to 1) identify the frequency of abnormal ETT cuff inflation in anesthetized dogs, 2) evaluate ETT cuff inflation with 3 devices (regular syringe, Tru-CuffTM syringe, AG Cuffill syringe) in achieving proper cuff pressure (20-30 cmH2O). Dogs undergoing general anesthesia at Purdue Veterinary Medicine Teaching Hospital (PVMTH) were included. The standard operating procedure (SOP) of PVMTH was used for ETT size selection and cuff inflation. The results of objective 1 showed that 50 of the 80 dogs required ETT cuff inflation. Among these 50 dogs, only 14% had proper cuff inflation; 76% of the cuffs were over-inflated and 10% were under-inflated. For objective 2, 90 dogs were equally assigned to the 3 devices for ETT cuff inflation and cuff pressure was assessed with an aneroid manometer. The results showed that 80% of the ETT cuffs were over-inflated with the regular syringe, whereas only 6.7% and 3.3% ETT cuffs were over-inflated with the Tru-CuffTM and AG Cuffill syringes, respectively. The AG Cuffill syringe treatment group had a significantly higher percentage of proper inflated ETT cuffs (86.7%; both p < 0.05) compared to the other two groups (regular [3.3%]; Tru-CuffTM [50%]). We concluded that there was a high frequency of improper ETT cuff inflation when using SOP coupled with a regular syringe. The use of an AG Cuffill syringe significantly reduced improper ETT cuff inflation.</p>

When to Say It: Establishing a Verbal Cue

Rulla, Emily 12 1900 (has links)
Dog trainers sometimes teach verbal cues by saying the cue as the dog is performing the desired behavior. However, there is disagreement about when to say the cue. In this study, a pet dog was trained to go to three different apparatus, the cue for each of which was given at a different time, in a multi-element design. The cue "hoop" was given just as the dog began to move to the hoop apparatus. The cue "carrier" was given as the dog was stepping into the carrier apparatus. The cue "platform" was given after the dog was sitting on the platform apparatus. To test if the dog had learned the cues, the trainer had the dog sit and gave the cue. During testing, if only the correct apparatus was present, the dog responded to all three cues. However, when all three apparatus were present, the dog only responded correctly to the "hoop" cue. This suggests that giving the cue just as the learner is beginning to perform the desired behavior is the most effective teaching method.

Trophic Relationships Among Caribou Calf Predators in Newfoundland

Zieminski, Chris 13 July 2016 (has links)
Using specially trained scat detection dogs we located fecal samples from black bear (Ursus americanus) and coyote (Canis latrans) throughout three study areas in Newfoundland, Canada, to describe these predators diet. Our sampling efforts were designed around seasons which were important to woodland caribou (Rangifer tarandus caribou) calving and resource use. We identified hairs microscopically to prey species and grouped other remains to facilitate our analysis. Bear exhibited an omnivorous diet throughout the study areas, ecological seasons and inside and outside the caribou calving grounds while coyote were limited to caribou, moose and snowshoe hare.

Child-Centered Canine-Assisted Therapy: An Investigative Look at Integrating Therapy Dogs into Child-Centered Play Therapy

Talley, Lindsay P 12 1900 (has links)
Play therapy and animal-assisted therapy are two specialized modalities within the field of counseling. Child-centered play therapy (CCPT) is a specific theoretical approach to play therapy that regards the therapeutic relationship as the primary healing factor. With much empirical support, CCPT is considered an effective mental health treatment option for working with children. Animal-assisted therapy in counseling (AAT-C) is acknowledged in the literature as a supplemental treatment modality to an existing counseling practice. Although past researchers have shown support for AAT-C as well as CCPT, there is a current dearth of literature examining the integration of these approaches. The present study sought to understand the approach of incorporating a therapy dog into child-centered play therapy while maintaining theoretical consistency. Using a constructivist grounded theory approach, I facilitated child-centered canine-assisted play therapy (C3APT) services for four children and reviewed the sessions with expert supervisors in AAT-C and CCPT. Three major themes emerged from the data: (a) principles of C3APT, (b) procedures of C3APT, and (c) relational dynamics. Implications for clinical practice and training of both therapy dogs and C3APT practitioners are also discussed.

Prosocial Rescue Behavior in Pet Dogs

January 2019 (has links)
abstract: ABSTRACT Domestic dogs have assisted humans for millennia. However, the extent to which these helpful behaviors are prosocially motivated remains unclear. To assess the propensity of pet dogs to spontaneously and actively rescue distressed humans, this study tested whether sixty pet dogs would release their seemingly trapped owners from a large box. To examine the causal mechanisms that shaped this behavior, the readiness of each dog to open the box was tested in three conditions: 1) the owner sat in the box and called for help (“Distress” test), 2) an experimenter placed high-value food rewards in the box (“Food” test), and 3) the owner sat in the box and calmly read aloud (“Reading” test). Dogs were as likely to release their distressed owner as to retrieve treats from inside the box, indicating that rescuing an owner may be a highly rewarding action for dogs. After accounting for ability, dogs released the owner more often when the owner called for help than when the owner read aloud calmly. In addition, opening latencies decreased with test number in the Distress test but not the Reading test. Thus, rescuing the owner could not be attributed solely to social facilitation, stimulus enhancement, or social contact-seeking behavior. Dogs displayed more stress behaviors in the Distress test than in the Reading test, and stress scores decreased with test number in the Reading test but not in the Distress test. This evidence of emotional contagion supports the hypothesis that rescuing the distressed owner was an empathetically-motivated prosocial behavior. Success in the Food task and previous (in-home) experience opening objects were both strong predictors of releasing the owner. Thus, prosocial behavior tests for dogs should control for physical ability and previous experience. / Dissertation/Thesis / Masters Thesis Psychology 2019

Cognitive Bias as a Measurement of Emotional States in Dogs

Brännmark, Emma January 2020 (has links)
Cognitive bias can be used when determining emotional states in animals by assessing the animal’s perception of an ambiguous stimulus. In the concept of animal welfare, both physical health as well as mental health of animals are involved. Therefore, cognitive bias can be a valuable tool in order to measure the mental health of an animal. The aim of this paper is to summarize and discuss how cognitive bias tests have been used to assess emotional states in dogs. Cognitive bias tests in dogs have been used to evaluate the emotional state of a dog with behavioural problems. It has also been shown to be useful when studying the effect of enrichment in the form of natural behaviour, such as being allowed to use its olfactory sense to a greater extent. Additionally, the connection between personality and cognitive bias is discussed. Hence, assessing the emotional state of dogs can be valuable in a welfare perspective.
