    Inherited retinal diseases (IRDs), defined by dysfunction or progressive loss of photoreceptors, are disorders characterized by elevated heterogeneity, both at the clinical and genetic levels. Our main goal was to address the genetic landscape of IRD in the largest cohort of Spanish patients reported to date. A retrospective hospital-based cross-sectional study was carried out on 6089 IRD affected individuals (from 4403 unrelated families), referred for genetic testing from all the Spanish autonomous communities. Clinical, demographic and familiar data were collected from each patient, including family pedigree, age of appearance of visual symptoms, presence of any systemic findings and geographical origin. Genetic studies were performed to the 3951 families with available DNA using different molecular techniques. Overall, 53.2% (2100/3951) of the studied families were genetically characterized, and 1549 different likely causative variants in 142 genes were identified. The most common phenotype encountered is retinitis pigmentosa (RP) (55.6% of families, 2447/4403). The most recurrently mutated genes were PRPH2, ABCA4 and RS1 in autosomal dominant (AD), autosomal recessive (AR) and X-linked (XL) NON-RP cases, respectively; RHO, USH2A and RPGR in AD, AR and XL for non-syndromic RP; and USH2A and MYO7A in syndromic IRD. Pathogenic variants c.3386G > T (p.Arg1129Leu) in ABCA4 and c.2276G > T (p.Cys759Phe) in USH2A were the most frequent variants identified. Our study provides the general landscape for IRD in Spain, reporting the largest cohort ever presented. Our results have important implications for genetic diagnosis, counselling and new therapeutic strategies to both the Spanish population and other related populations.This work was supported by the Instituto de Salud Carlos III (ISCIII) of the Spanish Ministry of Health (FIS; PI16/00425 and PI19/00321), Centro de Investigación Biomédica en Red Enfermedades Raras (CIBERER, 06/07/0036), IIS-FJD BioBank (PT13/0010/0012), Comunidad de Madrid (CAM, RAREGenomics Project, B2017/BMD-3721), European Regional Development Fund (FEDER), the Organización Nacional de Ciegos Españoles (ONCE), Fundación Ramón Areces, Fundación Conchita Rábago and the University Chair UAM-IIS-FJD of Genomic Medicine.

    The aims of the present study were to examine the variability of testosterone secretion in the Virginia Opossum over a 24 h period and to develop a testosterone stimulation test that would provide an index of the prevailing testosterone biosynthetic capacity of the testes; the latter was used to clinically evaluate the efficacy of a gonadotrophin-releasing hormone agonist contraceptive. Sexually-mature captive opossums (n = 12) located in Africam Safari (Mexico) sampled every 12 h over 24 h consistently showed basal

    ENCUENTROS. REVISTA DE CIENCIAS HUMANAS, TEORÍA SOCIAL Y PENSAMIENTO CRÍTICO es una revista auspiciada por el Centro de Estudios Geo-Históricos y Socio-Culturales de la Universidad Nacional Experimental Rafael María Baralt. Su publicación es periódica (semestral). Es una revista que se define como un medio alternativo que asume el compromiso de analizar y reflexionar sobre los procesos, dinámicas y coyunturas históricas que viven y sienten nuestras sociedades. También es un proyecto que acompaña los aportes a nuevas teorías para re-interpretar nuestro devenir histórico. De manera que es una revista crítica y decolonial. Sus áreas temáticas abordan las CIENCIAS HUMANAS (Filosofía, Historia, Educación, Letras) TEORIAS SOCIALES (Antropología, Sociología,) Y EL PENSAMIENTO CRITICO ALTERNATIVO (Interculturalidad, Epistemologías del sur, Filosofía de la Liberación, Decolonialidad) fundado en Latinoamérica.Presentacion p.9 / El rol emancipador de la episteme politica intercultural en America Latina p.11 / Una mira critica al proceso politico del movimiento indigena boliviano y su apuesta en la refundacion del Estado p.11 / Pensar al Estado: democracia y plurinacionalidad.
