Neurobiology of rodent self-grooming and its value for translational neuroscience

Self-grooming is a complex innate behaviour with an evolutionarily conserved sequencing pattern and is one of the most frequently performed behavioural activities in rodents. In this Review, we discuss the neurobiology of rodent self-grooming, and we highlight studies of rodent models of neuropsychiatric disorders-including models of autism spectrum disorder and obsessive compulsive disorder-that have assessed self-grooming phenotypes. We suggest that rodent self-grooming may be a useful measure of repetitive behaviour in such models, and therefore of value to translational psychiatry. Assessment of rodent self-grooming may also be useful for understanding the neural circuits that are involved in complex sequential patterns of action.National Institutes of Health (U.S.) (Grant NS025529)National Institutes of Health (U.S.) (Grant HD028341)National Institutes of Health (U.S.) (Grant MH060379

Caracterización de la enfermedad de la artritis y encefalitis caprina en las provincias de Salta y Jujuy

La artritis y encefalitis Caprina (CAEV) puede presentar diferentes síntomas clínicos, siendo la artritis la más común. A fin de caracterizar la presencia de enfermedades en las majadas caprinas del noroeste argentino, se llevó a cabo una encuesta sanitaria a productores, con toma de muestras biológicas para el diagnóstico de enfermedades en la que fue incluida CAEV. Se efectuó un análisis serológico con un ELISA indirecto y se completó con un examen clínico general de los animales y toma de muestra de necropsia de algunos de los casos. En la Provincia de Salta, tres establecimientos fueron positivos, con un 6,25% de prevalencia. La seroprevalencia del hato con seguimiento de caso fue del 55% mientras que el 48% presentó signos clínicos donde la artritis de la articulación carpal fue la más frecuentemente afectada. El virus CAEV está distribuido en la provincia de Salta y la severidad de las lesiones observadas sugiere la presencia de nuevas cepas que deben ser investigadas conjuntamente al desarrollo de capacidades locales para el diagnóstico, clave de cualquier plan de erradicación. SUMMARY. Characterization of caprine arthritis-encephalitis disease in Salta and Jujuy provinces. Caprine arthritis and encephalitis virus (CAEV) may present different clinical symptoms, with arthritis being the most common. In order to characterize the presence of diseases in goats from the Argentinean northwest, a sanitary survey was carried out to producers, with biological sampling for the diagnosis of diseases in which CAEV was included. A serological analysis was performed with an indirect ELISA and was completed with a general clinical examination of the animals and a necropsy sample collection of some of the cases. In the Province of Salta, three establishments were positive, with a prevalence of 6.25%. The serum prevalence of the herd with case follow-up was 55%, while 48% presented clinical signs where arthritis of the carpal joint was most frequently affected. The CAEV virus is spread in the province of Salta and the severity of the observed lesions suggests the presence of new strains that should be investigated in combination with the development of local capacities for diagnosis, this is the key to any eradication plan

Graft-Versus-Lymphoma Effect in Relapsed Peripheral T-Cell Non-Hodgkin's Lymphomas After Reduced-Intensity Conditioning Followed by Allogeneic Transplantation of Hematopoietic Cells.

RIC followed by allogeneic stem-cell transplantation is feasible, has a low treatment-related mortality, and seems to be a promising salvage treatment for relapsed PTCL. These findings suggest that the existence of a graft-versus-T-cell lymphoma effec
