Twenty six years of wheat breeding activities at IAPAR.

The description of the IAPAR wheat breeding program in its 26 th years of existence aims at presenting its major achievements giving an idea of the program size, breeding objectives and methodology. A germplasm flow chart will show the steps by which the populations have to follow starting either from crosses or from introductions until an advanced inbred line can be evaluated and elected as a new cultivar. A list of 23 wheat cultivars released by the program along with their pedigrees is presented as a special contribution. From the recent developed cultivars, data on grain yield, agronomic characteristics, technological quality and kernel properties are presented. The pedigree description for IAPAR 53 and the development of IPR 85 are presented in some detail. New biotechnological tools to help wheat breeding become more efficient are discussed

Clinical leishmaniosis in a domestic ferret (Mustela putorius furo) treated with miltefosine plus allopurinol: Serological and clinical follow-up

The published information on the treatment of mustelid leishmaniosis is extremely scarce because there are only two case reports available. In one case, a domestic ferret (Mustela putorius furo) was treated with a combination of meglumine antimoniate plus allopurinol and, in the other case, a therapeutic regimen with allopurinol was administrated to a Eurasian otter (Lutra lutra). This article describes for the first time a combined therapeutic protocol with miltefosine (2 mg/kg once a day during 28 days per os), and allopurinol (10 mg/kg twice a day PO sine die) in a domestic ferret with splenomegaly, lymphadenomegaly and a facial pyogranulomatous dermatitis, with a moderate level of antibodies to Leishmania infantum. © 2021 Elsevier B.V

A cross-sectional study of Leishmania infantum infection in stray cats in the city of Zaragoza (Spain) using serology and PCR

Background: Feline leishmaniosis is a vector-borne parasitic disease caused by Leishmania spp. Leishmania infection in dogs is prevalent in the Mediterranean basin, but in other animals, such as cats, it could also play a role in the epidemiology of the disease. Information on the geographical distribution and epidemiological features of L. infantum infection in cats is scarce, particularly in urban stray cats living in regions where canine leishmaniosis is endemic. As diagnosis can be challenging, combining different serological and molecular methods is a useful approach. Our aim was to investigate the prevalence of infection of L. infantum in apparently healthy stray cats in an endemic region of Spain (Zaragoza city) using serological and molecular methods, and to compare the results of the different techniques. Methods: The prevalence of Leishmania infection was studied in stray cats captured in urban and peri-urban areas of Zaragoza. Blood was collected from each animal for serology and molecular analysis. Three serological methods, namely the immunofluorescent antibody test (IFAT), enzyme-linked immunosorbent assay (ELISA) and western blot (WB), were used to detect L. infantum antibodies and a real-time PCR (qPCR) assay was used to detect L. infantum DNA. The results were analyzed by Fisher’s exact test and Cohen’s kappa statistic (¿) to assess the level of agreement between the diagnostic techniques. Results: Serological analysis of blood samples from 180 stray cats revealed 2.2% (4/179) Leishmania infection positivity by IFAT, 2.8% (5/179) by ELISA and 14.5% (26/179) by WB. Leishmania DNA was detected by qPCR in 5.6% (10/179) of the cats. Sixteen cats (8.9%) tested positive by only one serological technique and four tested positive by all three serological methods used. The overall rate of infected cats (calculated as the number of cats seropositive and/or qPCR positive) was 15.6%, and only two cats tested positive by all the diagnostic methods. A significant association was found between male cats and a positive qPCR result. Comparison of the techniques revealed a fair agreement in seropositivity between blood qPCR and IFAT (¿ = 0.26), blood qPCR and ELISA (¿ = 0.24), WB and ELISA (¿ = 0.37) and WB and IFAT (¿ = 0.40). The highest agreement between seropositive results was between IFAT and ELISA (¿ = 0.89), and the lowest was between blood qPCR and WB (¿ = 0.19). The prevalence of the feline leukemia virus antigen was 4.49% (8/178 cats) and that of the feline immunodeficiency virus (FIV) antibody was 6.74% (12/178), while co-infection with both retroviruses was observed in one female cat (1/178). Leishmania ELISA and IFAT seropositivity were statistically associated with FIV status by the chi-square test. Conclusions: The results obtained in this study, using serological tests and qPCR, indicate the existence of L. infantum asymptomatic infection in apparently healthy stray cats in the city of Zaragoza, an endemic area in Spain.

Chronicle of an early demise, surname extinction in the fifteenth and the seventeenth centuries

This is the Author’s Original Manuscript of an article published by Taylor & Francis in Historical Methods: A Journal of Quantitative and Interdisciplinary History on 2018, available online: http://www.tandfonline.com/10.1080/01615440.2018.1462747It has been amply demonstrated that individuals' reproductive capability is the key explanatory phenomenon for understanding onomastic disappearance during the early modern period. This article analyzes the evolution and consequences of surname extinction in a specific population: Catalonia in the sixteenth and seventeenth centuries. In this article two aspects are examined. First, the observed disappearance of surnames is estimated through historical data collected in the Llibres d'Esposalles (Marriage Books) from 1481 to 1600 at Barcelona Cathedral. Second, the estimated natural extinction of those surnames registered in 1481 is forecast by applying a statistical branching processResearch has been funded by Projects MTM2016-76969-P (Spanish State Research Agency, AEI) and MTM2013-41383-P (Spanish Ministry of Economy, Industry and Competitiveness), both co-funded by the European Regional Development Fund (ERDF), IAP network from Belgian Science Policy.

Análisis del rendimiento académico en los estudios de informática de la Universidad Politécnica de Valencia aplicando técnicas de minería de datos

En este trabajo presentamos un análisis del rendimiento académico de los alumnos de nuevo ingreso en la titulación de Ingeniería Técnica en Informática de Sistemas de la Universidad Politécnica de Valencia (UPV) a lo largo de tres cursos, aunque también se ha trabajado con las titulaciones de Ingeniería Técnica en Informática de Gestión y de Ingeniería Informática. Este análisis relaciona el rendimiento con las características socioeconómicas y académicas de los alumnos, que se obtienen en el momento de su matrícula, y que se recogen en la base de datos de la universidad. Hemos definido un indicador del rendimiento para cada alumno, teniendo en cuenta las calificaciones obtenidas y las convocatorias utilizadas. Para el estudio utilizamos técnicas de minería de datos, que pretenden determinar qué nivel de condicionamiento existe entre dicho rendimiento y características como el nivel de conocimientos de entrada del alumno, su contexto geográfico y sociocultural, etc… Esto proporciona una herramienta importante para la acción tutorial, que puede apoyarse en las predicciones de los modelos que se obtienen para encauzar sus recomendaciones y encuadrar las expectativas y el esfuerzo necesario para cada alumno, lógicamente dentro de la cautela habitual a la hora de tratar modelos inferidos a partir de datos.Universidad Politécnica de Valencia, a través del programa PACE

Equine penile squamous cell carcinoma: expression of biomarker proteins and EcPV2

Equine penile squamous cell carcinoma (EpSCC) is a relatively common cutaneous neoplasm with a poor prognosis. In this study, we aimed to determine the protein expression and colocalisation of FRA1, c-Myc, Cyclin D1, and MMP7 in normal (NT), tumour (T), hyperplastic epidermis and/or squamous papilloma (Hyp/Pap), poorly-differentiated (PDSCC), or well-differentiated (WDSCC) EpSCC using a tissue array approach. Further objectives were to correlate protein expression to (i) levels of inflammation, using a convolutional neural network (ii) equine papillomavirus 2 (EcPV2) infection, detected using PCR amplification. We found an increase in expression of FRA1 in EpSCC compared to NT samples. c-Myc expression was higher in Hyp/Pap and WDSCC but not PDSCC whereas MMP7 was reduced in WDSCC compared with NT. There was a significant increase in the global intersection coefficient (GIC) of FRA1 with MMP7, c-Myc, and Cyclin D1 in EpSCC. Conversely, GIC for MMP7 with c-Myc was reduced in EpSCC tissue. Inflammation was positively associated with EcPV2 infection in both NT and EpSCC but not Hyp/Pap. Changes in protein expression could be correlated with EcPV2 for Cyclin D1 and c-Myc. Our results evaluate novel biomarkers of EpSCC and a putative correlation between the expression of biomarkers, EcPV2 infection and inflammation
