ABSTRACT
The Amyotrophic Lateral Sclerosis (ALS) is a multisystemic disorder. It is considered a neuromuscular disease but also involves cognitive (executive functions, social cognition, attention, memory and language), emotional or behavior changes in over 50% of the reported cases and to of frontotemporal diagnosis lobar degeneration of behavioral variant in up to 15% of the cases. For this reason, the presence of cognitive and motivational problems was analysed in a Spanish sample of ALS patients through the prefrontal symptoms inventory (PSI) to determine applicability in this disease STI. A sample of 31 patients with a potential ALS or definitive diagnostic criteria according to El Escorial was used. Obtained results ISP were compared with a sample of 31 healthy people in the same proportions of gender, age and education level. Obtained results showed a not significant difference between the two populations in the motivational factor problems, related to the depression symptomatology frequently associated with ALS. A significant positive correlation between age at diagnosis and the scale of the motivational problems was observed, with a not significant trend related to problems in the executive control and in social the behavior control and with the age at diagnosis, in the same sense with age at diagnosis. Therefore, it can be concluded that, despite the results obtained, emotional and behavioral deficits in ALS patients and symptoms related to frontotemporal dementia (among others, anosognosia or lack of consciousness symptoms) could have interfered in patient perception about their symptomatology

The population structure of the Murciano-Granadina breed was determined using 25 microsatellites from 266 goats of seven populations. The results of the genetic differentiation analysis showed that it is possible to differentiate the Murciana and Granadina populations even though a low F ST value (0.0432) had been obtained. Individuals could be assigned to their populations with a success rate of more than 80 percent. Bayesian-based clustering analysis of allele frequencies and multivariate analysis revealed that Murciana and Granadina populations were grouped in different clusters since K=3. The results demonstrate that Murciana and Granadina are still two different genetic groups included into Murciano-Granadina denomination. There is the opportunity to the genetically manage these populations, under a single herd-book but adding the necessary modifications to respect the conservation of the genetic diversity based on the use of multibreed models of genetic evaluation.
Determinou-se a estrutura da raça Murciano-Granadina, usando-se 25 microssatélites e 266 animais de sete populações. Os resultados da diferenciação genética mostram que é possível diferenciar populações de Murciana e Granadina, apesar dos baixos valores de F ST obtidos - 0.0432. Os indivíduos foram designados às suas populações com taxa de sucesso superior a 80 por cento. A análise bayesiana de agrupamento das frequências alélicas e a análise multivariada revelaram que as populações Murciana e Granadina foram agrupadas em diferentes clusters, uma vez que o melhor K obtido foi três. Os resultados demonstraram que Murciana e Granadina ainda são dois grupos genéticos distintos incluídos na denominação Murciano-Granadina. É possível manejar geneticamente essas populações dentro de um único livro de registro, porém adotando-se as modificações necessárias em relação à conservação e à diversidade genética, com base no uso de modelos de avaliação multirracial.
