“…In addition to behavioural and clinical measurements, blood sampling has been widely used to monitor animal responses to stress (Haverbeke et al, 2008). However, in some cases, the restraint and handling procedures required for blood sampling have been shown to be themselves stressful (Kobelt et al, 2003).…”

Exercise has been shown to increase mRNA expression of a growing number of genes. The aim of this study was to assess if mRNA expression of the metabolism-and oxidative stress-related genes GLUT4 (glucose transporter 4), COX2 (cyclooxygenase 2), SOD1 (superoxide dismutase 1) and HSP70 (heat shock protein 70) in saliva changes following acute exercise stress in dogs. For this purpose, 12 avalanche dogs of the Italian Military Force Guardia di Finanza were monitored during simulation of a search for a buried person in an artificial avalanche area. Rectal temperature (RT) and saliva samples were collected the day before the trial (T0), immediately after the descent from a helicopter at the onset of a simulated avalanche search and rescue operation (T1), after the discovery of the buried person (T2) and 2 h later (T3). Expressions of GLUT4, SOD1, COX2 and HSP70 were measured by real-time PCR. The simulated avalanche search and rescue operation was shown to exert a significant effect on RT, as well as on the expression of all metabolismand oxidative stress-related genes investigated, which peaked at T2. The observed expression patterns indicate an acute exercise stress-induced upregulation, as confirmed by the reductions in expression at T3. Moreover, our findings indicate that saliva is useful for assessing metabolism-and oxidative stress-related genes without the need for restraint, which could affect working dog performance.

Em humanos, este tremor independente do medo foi estudado em situações de alegria extrema, e algumas pessoas com transtorno de conversão apresentam tremores na demonstração de alegria por haver conectividade entre a amígdala e regiões associadas com a preparação motora (VOON et al, 2010 KING et al, 2000;HENNESSY et al, 2001;HAVERBEKE et al, 2008;KERSWELL et al, 2009), abanar a cauda.

“…Common sense about cortisol elevations as negative events or preventing dogs from undergoing stress may be partially incorrect since hormonal fluctuations can make dogs feel new environmental challenges (HAVERBEKE et al, 2008;ASCHBACHER et al, 2013;GOMES DA SILVA et al, 2013). Exaggerated hormonal elevations may lead to health problems, as low immune response, psychological and neurogenic disturbances as well as physiological and behavioral alterations (DE ALMEIDA et al, 2013).…”

“…Two factors are related to stress: interleukin 6 (IL6) to acute stress (HEINRICH et al, 2003;KUNZ-EBRECHT et al, 2003;CARROLL et al, 2011;CAMPISI et al, 2012;IZAWA et al, 2013b), and cortisol to chronic stress (BEERDA et al, 1997;BEERDA et al, 1999b;BEERDA et al, 2000;ACCORSI, 2008;AGUILERA, 2011). It has been reported that cortisol influences learning in dogs under stress (HAUBENHOFER; KIRCHENGAST, 2007;HAVERBEKE et al, 2008). IL6 participates in the first general inflammatory response to any injury (BLACK, 2002), including psychic and immediate source as acute stress (HEINRICH et al, 2003;NAS et al, 2011;IZAWA et al, 2013a), and can interfere with cognitive performance, since it stimulates aggression when acting in the limbic system and amygdala (ARHANT et al, 2010;CARROLL et al, 2011;DE ALMEIDA et al, 2013).…”

Á DEUS, que no silêncio das madrugadas, permitiu-me conhecê-Lo, entendê-Lo e me ensinou a conversar com Ele. Volto para casa com minha fé descoberta e com uma experiência íntima muito forte estabelecendo esta aliança. Graças dou! À minha mãe Otilia Wisniewski Lesnau pelas vezes em que cruzou o Brasil para socorrer minha família na minha ausência e o apoio que sempre ofereceu. A todos vocês, muito obrigado! Epígrafe "Dizem que a oportunidade é uma deusa que tem cabelo na testa, portanto você tem de apanhá-la quando ela vem de frente porque depois que ela passa, a única coisa a fazer é se lamentar". The mechanism of stress is already known and can be divided in two stages: acute stress, which releases thermogenic factors and inflammatory -mediated interleukin 6 (IL6) and chronic stress, which suppresses the inflammatory response and is mediated by the presence of cortisol. When stray dogs are housed in shelters, they undergo a period of adaptation; however, until now there is not a ressocialization program at the governmental level aiming to improve their welfare along with their new owners. The ressocialization program beginning when dogs arrive to the shelter and the correlation of dogs´ behavior with physiological and endocrine parameters related to stress have not yet been described , which raises the hypothesis that it can decrease the traumatic impact of abandonment. Twenty seven healthy bitches were divided into 3 groups: with owners, abandoned not trained and abandoned trained.The trained and abandoned dogs were later adopted. The training lasted 15 min / day for 21 days. The behavioral assessment (ethogram and ethotest) was performed every 7 days and physiological parameters assessment (heart rate, respiratory rate, blood oxygenation rate, pulse) as well as saliva collection, daily. After the adoption, the bitches were evaluated for 7 additional days. Data were analyzed by ANOVA, after testing the results for normality. The correlation between parameters was analyzed using the Pearson correlation test. Values were considered different at p < 0.05. The most surprisingly result was the maintenance of low levels of IL6 in trained dogs after neutering, whereas the other two groups showed a significant increase of IL6. The consequences of training were evident in ethograms after adoption: there was an improvement of the interaction of dogs with the new family, attitudes of playing were more numerous, and dogs showed a greater receptivity to the new owners. The tail wagging, as communication behavior, appeared much more frequently in trained dogs after adoption. Abandoned dogs after adoption manifested more idleness, discouragement and depression behaviors and reduced alertness.These results suggest that the training reassures bitches in the stressful shelter environment, improves their physiological parameters, controls fear behaviors making them more able to adapt to the new environment after adoption. There were no differences in cortisol among the groups (p > 0.05). However, IL-6 concentration was lower in ...
