Biochemical genetic typing of a Southern African endemic domestic dog breed from rural areas

Greyling, Letitia Maria 11 September 2008 (has links)
Electrophoresis (horizontal starch gel and PAGE) was used to study the genetic diversity and uniqueness of an endemic southern African domestic dog (Africanis) breed. The results were compared to those of three other populations/breeds: blood samples obtained from the Society for the Prevention of Cruelty to Animals (SPCA); indigenous Middle Eastern dog breed (the Saluqis) and hybrid (mongrel) dogs from the Jericho-area, near Brits (South Africa). Gene and phenotypic allele frequency and genetic differentiation were analysed at 21 protein coding loci. Nine polymorphic loci were identified (AK-1, -2, CK, PER, Hb, PA-1 to -3 and P-Tf). The average heterozygosity ranged from 0.106 to 0.159; the percentage of polymorphic loci were the least in the Saluqi (23.81%) and ranged to 33.33% in the Jericho breed; and the mean number of alleles per locus varied from 1.33 (Saluqi) to 1.43 (Jericho). Significant deviations (P<0.05) of allele frequencies from expected Hardy-Weinberg proportions occurred in loci AK-1, -2, Hb and P-Tf. These loci can serve as markers to define groups (i.e. only Africanis showed the presence of private alleles, CK*B and PA-2*C). The genetic distance values (D78) were between 0.001 and 0.026, with the smallest distance between Africanis and Saluqi, and the largest distance between Jericho and Africanis. This former, small D-value indicates a close genetic relationship between Africanis and Saluqis, supporting archaeological evidence that the endemic Africanis breed has indeed been introduced from the Middle East thousands of years ago, and not through western influences. These results are discussed with specific reference to genetic variation and differentiation that makes the endemic southern African domestic dog breed unique. / Prof. F.H. Van der Bank

Efeito do meio de congelação sobre as características morfofuncionais do sêmen canino

Chirinéa, Viviane Helena [UNESP] January 2003 (has links) (PDF)

As características morfofuncionais foram analisadas no sêmen in natura (T1), refrigerado (T2) e descongelado (T3). As amostras foram avaliadas para: motilidade e vigor espermático, teste hiposmótico, integridade de membrana espermática, morfologia espermática e análise ultra-estrutural, além da mensuração do pH. Após a diluição com os diferentes meios, o sêmen foi envasado em palhetas francesas de 0,5mL, contendo 40 x 106 espermatozóides móveis/palheta, e mantidas por 60 minutos à 5ºC (T2); logo após, foram transferidos para o vapor de nitrogênio durante 20 minutos, e por fim, mergulhadas em nitrogênio. O armazenamento das palhetas foi em botijão criogênico. As palhetas foram descongeladas a 70ºC por 8 segundos. A análise de variância mostrou influência do efeito animal nas variáveis analisadas, com exceção da motilidade espermática e integridade de membrana espermática. O teste hiposmótico, a integridade de membrana espermática e o pH, nas amostras refrigeradas (T2), apresentaram diferença estatística significativa (p<0,05) entre os meios, com superioridade do MP50. Nas análises pós-descongelação (T3), não foram observadas diferenças significativas entre as variáveis estudadas para os dois meios. A análise ultra-estrutural, mostrou edema de membrana plasmática e acrossomal, nas diferentes etapas do processo de congelação. Em conclusão, considerando-se as características morfofuncionais do sêmen canino pós-descongelação, os meios diluidores demonstraram igualdade. / The objective of this study was to verify the efficiency of two different extenders for freezing dog semen: Tris/Glycerol and MP50. Ten ejaculates from different adult dogs were collected by digital manipulation. Seminal characteristics were evaluated in three different moments, fresh (T1), cooled (T2) and thawed (T3) semen for sperm motility and vigor, hypo-osmotic swelling test, sperm membrane integrity, sperm morphology, ultrastructural analysis and seminal pH. The samples were divided into two equal parts and each part was mixed with one extender type. After mixing, samples were packaged in 0,5mL French straws with 40 x 106 spermatozoa/straw. Semen samples were kept at 50C for 60 minutes (T2); then frozen in static vapor of nitrogen for the following 20 minutes and immersed in liquid nitrogen until being thawed in 700 C water for 8 seconds (T3). By analysis of variance, it would be possible to verify the animal effect on almost all variables observed in this study, except for sperm motility and membrane integrity. For cooled semen (T2), MP50 were significantly better for hypo-osmotic swelling test, sperm membrane integrity and pH (p<0,05) than Tris/Glycerol. For thawed semen (T3), there was no significant difference between extenders. By ultrastructural analysis, it was possible to verify swelling plasma and acrosomal sperm membranes in the different stages of freezing process. In conclusion, the extenders showed the same results as to morphofunctional characteristics the semen canine thawed.

Experiences, characteristics and treatment of women suffering from dog phobia

Hoffmann, WA, Human, LH 28 April 2015 (has links)
Abstract Dog phobia is a complex psychological phenomenon classified under the anxiety disorders. Twelve female students suffering from dog phobia participated in this qualitative study which included an initial screening, therapeutic intervention and eight-month follow-up. Initial screening was conducted by means of a Fear Survey Schedule and observational assessment of non-verbal behavior during a behavioral approach test (dog stimulus). Therapeutic intervention involved a combination of systematic desensitization and instructional learning. Qualitative data analysis followed a phenomenological approach. The results indicate that the onset age of dog phobia varied from early childhood to late adolescence. Twothirds of the participants reported a direct traumatic event as the onset context of their dog phobia, while 17% reported vicarious learning contexts and 17% an inability to recall the onset context. The most widely used sensory focal mode of perception during contact with dogs was visual cues, followed by auditory cues. Half of the participants reported “eye” aspects as the fear-evoking stimulus. A wide variety of anxieties and fears were found to co-occur with dog phobia, although some participants were still able to accommodate dogs and other companion animals in their lives. The poststudy follow-up indicated that the intervention yielded significant real life improvement in 75% of the cases. The implications of this study for therapeutic situations are discussed.
