Indirect MHC typing by microsatellites (STR) provides data on genetic diversity and population structure, and provides knowledge of selective and evolutionary processes. In order to characterize a sample of Arab horses, we identified MHC haplotypes based on three STRs (UM011, DRB2-STR2 and COR112) covering a region of ~1Mpb. Genomic DNA was extracted from blood and hair of 30 horses from five farms of the province of Buenos Aires. STRs were amplified with fluorescent primers and typed in an automated sequencer. Population and diversity parameters were estimated. Haplotype detection was performed by segregation analysis and with the PHASE program for reconstructing haplotypes. Of the 24 haplotypes identified, 12 were verified by segregation in the Stud Book pedigree records. Our results showed linkage with known equine leukocyte antigen (ELA) class II alleles. The number of haplotypes identified allowed to expand the estimates of diversity in the equine MHC. This methodology is a useful tool and an alternative approach to type MHC in horse lineages and immune-related population studies.","PeriodicalId":7773,"journal":{"name":"Analecta Veterinaria","volume":"37 1","pages":"003-003"},"PeriodicalIF":0.0,"publicationDate":"2017-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43932781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hepatozoon canis y Hepatozoon americanum son las dos especies que pueden infectar al perro. La presentacion clinica de la infeccion con Hepatozoon canis es muy variable, pudiendo ser asintomatica o manifestarse con signos de enfermedad leves a severos. Los examenes hematologicos revelan ligera anemia no regenerativa, marcada leucocitosis neutrofilica con desvio a la izquierda y monocitosis en los casos de hepatozoonosis clinica. El diagnostico se realiza mediante la visualizacion mediante el microscopio optico de los gamontes en neutrofilos y monocitos en frotis de sangre coloreados. No existe, hasta el momento, un tratamiento eficaz para esta parasitosis. El farmaco mas utilizado es el dipropionato de imidocarb, aunque con resultados variables. El objetivo de este trabajo fue evaluar tres opciones terapeuticas para la erradicacion de Hepatozoon spp. de la sangre de perros infectados. Se utilizaron 18 perrosparasitados naturalmente y se evaluaron tres farmacos: dipropionato de imidocarb, toltrazuril y espiramicina. En todos los perros tratados disminuyo el promedio de infeccion, presentando similares valores medios de leucocitos infectados. El analisis estadistico arrojo una diferencia significativa solo en el tratamiento de la parasitosis con dipropionato de imidocarb. En virtud de los resultados obtenidos con los tratamientos llevados a cabo con los diferentes farmacos, se concluye que ninguno es totalmente efectivo para la desaparicion del parasito de la sangre, siendo el dipropionato de imidocarb el de mejor comportamiento.","PeriodicalId":7773,"journal":{"name":"Analecta Veterinaria","volume":"37 1","pages":"002-002"},"PeriodicalIF":0.0,"publicationDate":"2017-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42027310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They have been used especially to analyze neoplastic tissues. However, the advantages of this technique could be applied to other research areas such as embryology and histology. This study explores the use of tissue microarrays for morphological and molecular analysis of normal tissues from animals. A total of 82 samples of normal skin from prenatal and postnatal dogs were selected and used to construct the array. A large number of sections from this array block were obtained and routine stain and immunohistochemistry techniques were applied. The results show the effectiveness of the technique for morphological and molecular analysis of a large number of normal tissue samples simultaneously. This allows the standardized assessment of tissues, thus reducing the variability that can occur when testing is performed on individual samples.","PeriodicalId":7773,"journal":{"name":"Analecta Veterinaria","volume":"37 1","pages":"008-008"},"PeriodicalIF":0.0,"publicationDate":"2017-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43617054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Color Doppler was used to localize uterine arteries at both sides of the body and pulsed-wave Doppler was performed to obtain the waveforms. Peak systolic velocity (PSV) and end diastolic velocity (EDV) were measured. Resistance index [RI=(PSV−EDV)/PSV] was automatically calculated. Values of TD, E, PSV, EDV and RI were analyzed by repeated measures ANOVA followed by a Tukey test. An analysis of covariance was employed to evaluate the effect of number of puppies on RI.
