Efeito de um protocolo de treinamento concorrente sobre fatores de risco para o acúmulo de gordura hepática de adolescentes obesos

Study Design: Prospective study Objective: To evaluate the effect of a protocol of concurrent training lasting 16 weeks on risk factors for the accumulation of hepatic fat in obese youth. Methods: 38 obese children and adolescents of both sexes, between 12 and 15 years old. The obesity was attested by the percentage of body fat, which was estimated by dual-energy X-ray absorptiometry (DEXA). Additionally, the amount of fat located in the trunk (kg) was estimated too. Before and after the intervention, the youths underwent biochemical blood tests (fasting complete lipid profile [mg / dL]) and ultrasonography of the liver (right size Wolves [LD cm] and left [LE in cm]). The intervention consisted of concurrent training (strength training [30 minutes] and endurance training [30 minutes]) with three sessions per week, totaling 180 minutes a week, for ten weeks. Statistical analysis was made by the test t of Student for paired data using SPSS software (17.0) and significance statistical fixed at p <5%. Results: After the intervention, significant improvements were observed in the percentage of total fat (PRE: 45.1 ± 5.3 and POST: 41.7 ± 5.6, p = 0.001) and in the trunk region (PRE: 46, 5 ± 5.6 and POST: 42.9 ± 6.3, p = 0.001). For lipid profile, reduction in total cholesterol (PRE: 164 ± 34 and POST: 148 ± 29, p = 0.001), triglycerides (PRE: 118 ± 59 and POST: 104 ± 53, p = 0.002) and lipoproteins density (PRE: 100 ± 29 and POST: 85 ± 26, p = 0.001), but not for high-density (p = 0.981). Both the LE (PRE: 8.8 ± 1.4 and POST: 7.8 ± 1.3, p = 0.001) and LD (PRE: 13.6 ± 1.3 and POST: 12.9 ± 1, 1, p = 0.001) experienced a decrease in its proportions. Conclusion: The concurrent training was effective in combating some risk factors to the accumulation of fat in the liver, as well as in reducing fat in both lobes of the organ in young obese.

Wolf presence in the ranch of origin: Impacts on temperament and physiological responses of beef cattle following a simulated wolf encounter

This experiment evaluated temperament, vaginal temperature, and plasma cortisol in beef cows from wolf-naive and wolf-experienced origins that were subjected to a simulated wolf encounter. Multiparous, pregnant, nonlactating Angus-crossbreed cows from the Eastern Oregon Agricultural Research Center located near Burns, OR (CON; n = 50), and from a commercial operation near Council, ID (WLF; n = 50), were used. To date, grey wolves are not present around Burns, OR, and thus CON were naive to wolves. Conversely, wolves are present around Council, ID, and WLF cows were selected from a herd that had experienced multiple confirmed wolf-predation episodes from 2008 to 2012. Following a 50-d commingling and adaptation period, CON and WLF cows were ranked by temperament, BW, and BCS and allocated to 5 groups (d 0; 10 CON and 10 WLF cows/group). Groups were individually subjected to the experimental procedures on d 2 (n = 3) and d 3 (n = 2). Before the simulated wolf encounter, cow temperament was assessed and blood samples and vaginal temperatures (using intravaginal data loggers) were collected (presimulation assessments). Cows were then sorted by origin, moved to 2 adjacent drylot pens (10 WLF and 10 CON cows/pen), and subjected to a simulated wolf encounter event for 20 min, which consisted of 1) cotton plugs saturated with wolf urine attached to the drylot fence, 2) continuous reproduction of wolf howls, and 3) 3 leashed dogs that were walked along the fence perimeter. Thereafter, WLF and CON cows were commingled and returned to the handling facility for postsimulation assessments, which were conducted immediately after exposure to wolf-urine-saturated cotton plugs, wolf howl reproduction, and 20-s exposure to the 3 dogs while being restrained in a squeeze chute. Chute score, temperament score, and plasma cortisol concentration increased (P <= 0.01) from pre- to postsimulation assessment in WLF but did not change in CON cows (P >= 0.19). Exit velocity decreased (P = 0.01) from pre-to postsimulation assessment in CON but did not change (P = 0.79) in WLF cows. In addition, WLF cows had a greater (P = 0.03) increase in temperature from pre-to postsimulation assessments compared with CON cows. In conclusion, the simulated wolf encounter increased excitability and fear-related physiological stress responses in cows that originated from a wolf-experienced herd but not in cows that originated from a wolf-naive herd.

A identidade feminina em The Magic Toyshop: estudos de gênero no texto e na tela

Besides producing a vast literary work, Angela Carter (1940-1992) participated of the screenplay’s production for two movies based on her books, The Company of Wolves and The Magic Toyshop. Either through the influence that cinema had in her life or through the very own style of her writing, the relation of the British author with the seventh art is visible. Considering the importance of significations in literary works, this paper proposes a comparative study between Angela Carter’s The Magic Toyshop (1967) and the film of the same title, based on Carter’s novel, directed by David Wheatley and produced by Granada Television, in 1987. Based on Tania Carvalhal’s conception about intertextuality and film theories, the focus of this paper is the gender study, since its ideology is subscribed, represented and reproduced in every cultural practice, including literature and cinema. The characters construction in both cases, especially the female characters, is filled with symbols which are going to bring the film closer to the literary work and contribute to express the critics suggested in the work’s leading: the complaint to the patriarchal system. However, given the different nature of each work, it is necessary to stress that this present comparison doesn’t intend to establish a total identification between novel and film, but to set a dialogue between both, observing the approximation and distance of these two instances.

Bartonella clarridgeiae and Bartonella vinsonii subsp berkhoffii exposure in captive wild canids in Brazil

Wild canids are potential hosts for numerous species of Bartonella, yet little research has been done to quantify their infection rates in South America. We sought to investigate Bartonella seroprevalence in captive wild canids from 19 zoos in São Paulo and Mato Grosso states, Brazil. Blood samples were collected from 97 wild canids belonging to four different native species and three European wolves (Canis lupus). Indirect immunofluorescent antibody testing was performed to detect the presence of B. henselae, B. vinsonii subsp. berkhoffii, B. clarridgeiae, and B. rochalimae. Overall, Bartonella antibodies were detected in 11 of the canids, including five (12·8%) of 39 crab-eating foxes (Cerdocyon thous), three (11·1%) of 27 bush dogs (Speothos venaticus), two (8·7%) of 23 maned wolves (Chrysocyon brachyurus) and one (12·5%) of eight hoary foxes (Lycalopex vetulus), with titres ranging from 1:64 to 1:512. Knowing that many species of canids make excellent reservoir hosts for Bartonella, and that there is zoonotic potential for all Bartonella spp. tested for, it will be important to conduct further research in non-captive wild canids to gain an accurate understanding of Bartonella infection in free-ranging wild canids in South America.

Management of Wolf-Livestock Conflicts in Minnesota

In 1975, the gray wolf (Canis lupus) population in Minnesota was protected by the federal Endangered Species Act (USA). At that time, there were 500-750 wolves. By 2004, the population had grown to an estimated 3,020 wolves. Over time, conflicts between wolves and livestock increased. Wolf depredation control programs have been conducted by the U.S. Fish and Wildlife Service (1975-1986) and by the U.S. Department of Agriculture’s Wildlife Services program (1986 to present). In 1978, Minnesota’s wolves were reclassified from endangered to threatened which allowed authorized federal agents to lethally remove wolves that had depredated on livestock or pets. A State funded wolf compensation program was also established in 1978. Wildlife Services’ wolf damage management approach utilizes both nonlethal and lethal methods of control. Currently, wolf depredations are verified at 60-85 farms annually and 125-175 wolves are taken each year. Wolf compensation payments to livestock producers have averaged $67,111 per year during the past five years. Most livestock losses occur during spring and summer. Selective removal of depredating wolves, coupled with improvements in animal husbandry practices, has potential for reducing wolf-livestock conflicts. Minnesota’s wolf population is currently considered to be fully recovered and federal delisting is expected to occur in the near future.

WOLF CONTROL IN BRITISH COLUMBIA, CANADA

Up to 1949, the Fish and Game Branch employed personnel, some of whom were temporary, to attempt control of the extremely high wolf pop¬ulations of the central and northern portions of British Columbia. Coyotes were also very numerous in the central and southern regions and had to be considered because of their depredations. The field men were keen and conscientious but their efforts were not co-ordinated. Control areas were severely restricted in size as techniques were not adaptable enough and because of a lack of manpower. Eventually, sheepmen went out of business entirely over wide areas, cattlemen were subjected to huge annual losses, and sportsmen were very concerned. However, stock losses constituted the major complaint and resulted in ranchers demanding action* Two major changes came out of this. First, the bounty on wolves was raised and second, the present Predator Control Division was formed. The administration was convinced that a force of experienced, fully-trained field staff under a single supervision would be far more effective than bounty payments. Unfortunately, bounties were in vogue during that time and forced the necessity of proving the worth of organized controls before any consideration could be given to the elimination of the bounty system.

Ecological genetics and conservation genomics of wolf (Canis lupus)

In the present work, we apply both traditional and Next Generation Sequencing (NGS) tools to investigate some of the most important adaptive traits of wolves (Canis lupus). In the first part, we analyze the variability of three Major Histocompatibility Complex (MHC) class II genes in the Italian wolf population, also studying their possible role in mating choice and their influence on fitness traits. In the second section, as part of a larger canid genome project, we will exploit NGS data to investigate the transcript-level differences between the wolf and the dog genome that can be correlated to domestication.

Landscape ecology and genetics of the wolf in Italy

This PhD Thesis includes five main parts on diverse topics. The first two parts deal with the trophic ecology of wolves in Italy consequently to a recent increase of wild ungulates abundance. Data on wolf diet across time highlighted how wild ungulates are important food resource for wolves in Italy. Increasing wolf population, increasing numbers of wild ungulates and decreasing livestock consume are mitigating wolf-man conflicts in Italy in the near future. In the third part, non-invasive genetic sampling techniques were used to obtain genotypes and genders of about 400 wolves. Thus, wolf packs were genetically reconstructed using diverse population genetic and parentage software. Combining the results on pack structure and genetic relatedness with sampling locations, home ranges of wolf packs and dispersal patterns were identified. These results, particularly important for the conservation management of wolves in Italy, illustrated detailed information that can be retrieved from genetic identification of individuals. In the fourth part, wolf locations were combined with environmental information obtained as GIS-layers. Modern species distribution models (niche models) were applied to infer potential wolf distribution and predation risk. From the resulting distribution maps, information pastures with the highest risk of depredation were derived. This is particularly relevant as it allows identifying those areas under danger of carnivore attack on livestock. Finally, in the fifth part, habitat suitability models were combined with landscape genetic analysis. On one side landscape genetic analyses on the Italian wolves provided new information on the dynamics and connectivity of the population and, on the other side, a profound analysis of the effects that habitat suitability methods had on the parameterization of landscape genetic analyses was carried out to contributed significantly to landscape genetic theory.

Verhaltensphysiologische Experimente zur Erkennung und Unterscheidung menschlicher Gesichter beim Haushund (Canis familiaris)

In der vorliegenden Arbeit wurde die Fähigkeit von Hunden zur Erkennung und Unterscheidung menschlicher Gesichter untersucht. Zu diesem Zweck wurden verschiedene Verhaltensexperimente mit fünf Hunden durchgeführt. Zunächst wurden die Hunde darauf dressiert, ein einlaminiertes DIN A4 Blatt mit einem Gesicht im Zentrum in der dafür vorgesehenen Apparatur mit der Schnauze zu berühren. Bei der Dressur wurden immer zwei Folien präsentiert, wobei nur eine Wahl, nämlich die des Dressurgesichts, durch Futtergabe belohnt wurde. Nach Abschluss der Dressurphase wurden die Hunde in Generalisationstests mit neuen Gesichtern konfrontiert, die für uns Menschen wenig bis keine direkte Ähnlichkeit mit dem Dressurgesicht aufwiesen. Um herauszufinden ob Hunde sich an der Größe orientieren, wurden einige der zuvor getesteten Gesichter um die Hälfte und mehr verkleinert. All diese Veränderungen beeinträchtigten die Fähigkeit der Hunde nicht, das Dressurgesicht bevorzugt zu wählen. Diese Ergebnisse veranlassten die Versuchsleiterin zu testen, ob Hunde sich an verschiedenen Bereichen im menschlichen Gesicht orientieren oder das Gesicht als Ganzes wahrnehmen. Zur Beurteilung wurden den Hunden abgeänderte Gesichter zum Einen ohne Haare und Ohren und zum Anderen nur Haare und Ohren ohne das Gesicht (homogen graue Fläche) präsentiert. Hier hatten die Hunde deutliche Schwierigkeiten, wenn die äußeren Konturen nicht mehr vorhanden waren. Bei diesen Versuchen blieben die Wahlen der Hunde nahe dem Zufallsniveau von 50%. Das Fehlen des Gesichts als solches erwies sich als unproblematisch, da allen Hunden die äußeren Konturen, in diesem Fall Haare und Ohren ausreichten, um das Dressurgesicht mit einer Wahlhäufigkeit signifikant über 70% wiederzuerkennen. Abschließend wurde untersucht, ob sich die Hunde durch das Zusammensetzen von zwei bzw. drei unterschiedlichen Gesichtern in ihrem Wahlverhalten beeinflussen lassen. Dazu wurden zwei unterschiedlichen Haarpartien verschiedene Gesichter zugeordnet. Ähnelten sich die äußeren Konturen fiel es den Hunden in dieser Versuchsreihe schwer die Dressurhaare wieder zu erkennen. Unterschieden sich die äußeren Konturen für unser menschliches Auge deutlich, so wählten alle Hunde die Haare und Ohren des Dressurgesichts mit einer Wahlhäufigkeit signifikant über dem Schwellenwert von 70%. Somit ist zu vermuten, dass sich im Laufe der Domestikation beim Hund keine Hirnregion ausgebildet hat, die speziell für die Gesichtserkennung von Menschen verantwortlich ist. Aus den Ergebnissen dieser Arbeit zur Gesichtserkennung beim Hund wird deutlich, dass es dem Hund möglich ist, Gesichter voneinander zu unterscheiden. Allerdings orientiert sich der Hund nicht an bestimmten Gesichtsregionen, sondern nutzt die äußeren Konturen als Wiedererkennungsmerkmal. Aus diesem Grund finden sich häufig Unsicherheiten bei Hunden, wenn ihnen bekannte Menschen plötzlich mit Hut oder Mütze begegnen und eine Erkennung über den Geruchssinn und die Stimme noch nicht stattgefunden hat. Bei der Beurteilung der Ergebnisse muss beachtet werden, dass den Hunden das menschliche Gesicht in Form von Bildern präsentiert wurde und somit keine Beeinflussung durch Bewegung im Gesicht gegeben war. Da das Bewegungssehen beim Hund sehr gut ausgebildet ist, achtet er im Alltag des Menschen sehr wahrscheinlich außerordentlich gut auf Augenbewegungen und Gesichtsmuskelbewegungen, um mit dem Sozialpartner Mensch zu kommunizieren. Weiterhin wäre es interessant herauszufinden, ob die Orientierung an den äußeren Konturen eine Folge der Domestikation und somit eine Adaptation an den Menschen und sein Ökosystem ist, oder ob Wölfe auch dazu in der Lage wären.
