Publication Geometric morphometrics of the human cervical vertebrae: sexual and population variations(Istituto Italiano di Antropologia, 2021) Palancar, Carlos A.; García Martínez, Daniel; Cáceres Monllor, David Antonio; Perea Pérez, Bernardo; Ferreira, María Teresa; Bastir, MarkusThis study aims to carry out the first geometric morphometric analysis of the 3D size and shape of the full series of cervical vertebrae delving into variability related to sex and population background. For this reason, we analyzed the cervical vertebrae of both males and females belonging to Europeans, Africans, and Greenland Inuit. We 3D-scanned a total of 219 cervical vertebrae of males and females of three different modern human populations (European, African, and Inuit). A minimum of 72 landmarks and curve semilandmarks were positioned in each of the 3D vertebral models. Landmark configurations were analyzed following the standards of 3D Geometric Morphometrics to test for size and shape differences related to sex or population variation. Results show that male cervical vertebrae are consistently larger than in females while no regular shape differences are observed between males and females in any of the populations. Sex differences in cervical lordosis are thus not supported at the skeletal level of the 3D shape. On the other hand, there is no evidence for population-specific differences in size while shape does vary considerably, possibly also in relation to eco-geographic factors of overall trunk shape. Cervical vertebrae in cold-adapted Inuit were consistently shorter than in Europeans and Africans. The cervical spine may show a different pattern than the thoracic and lumbar spine, which might be related to stronger integration with the cranium, head mobility, and soft-tissue dependence. Our findings suggest that morpho-functional interpretations of the cervical spine based on vertebral skeletal morphology requires caution.Publication Metodología para la valoración del daño bucodental(Universidad Complutense de Madrid, Servicio de Publicaciones, 2002) Perea Pérez, Bernardo; Roldán Garrido, Bernabé; Sánchez Sánchez, José AntonioEn la presente tesis doctoral se propone una metodología concisa y reglada para la valoración del daño bucodental y la forma de reflejarla en un informe pericial. También se desarrollan dos baremos. El primero, extenso y detallado, se indica para casos en los que el daño es exclusiva, o casi exclusivamente, dentario, como los derivados de un inadecuado ejercicio de la odontoestomatología. En este baremo, además de las funciones clásicas de los dientes: masticatoria, fonatoria y estética, se proponen dos funciones nuevas: la función prostodoncica y como patrimonio biológico. El otro baremo recogido es un resumen ponderado del primero y se recomienda para daños dentales derivados de accidentes de trafico. En la tesis también se estudian todos los casos odontoestomatológicos llegados a la clínica médico-forense de Madrid desde julio de 1987 a julio de 1993.Publication Observatorio Complutense para la seguridad clínica odontológica(2019-06-30) Perea Pérez, Bernardo; Labajo González, Elena; Santiago Sáez, Andrés Sebastián; Albarrán Juan, María ElenaPublication Observatorio Complutense para la Seguridad Clínica Odontológica(2021-06) Perea Pérez, Bernardo; Labajo González, Elena; Santiago Sáez, Andrés Sebastián; Albarrán Juan, María ElenaPublication ForenCAPS: canal de youtube complutense de antropología y odontología forense(2022-06-19) Benito Sánchez, María; Labajo González, Elena; Mata Tutor, Pilar Josefina; Mourin Moral, Francisco Javier; Moya Rueda, Ana Patricia; Perea Pérez, Bernardo; Rascón Risco, Mónica; Santiago Sáez, Andrés Sebastián; Villoria Rojas, Catherine del PilarForenCAPS es el canal de YouTube del Laboratorio de Antropología y Odontología Forense de la Universidad Complutense de Madrid. A través de él, queremos mostraros nuestro trabajo en forma de cápsulas cortas de temas de concretos de las ciencias forenses. Tenemos la identificación humana, la odontología forense y el estudio de lesiones como base de trabajo, pero usando las nuevas tecnologías disponibles podemos hilar mucho más fino. Usando este canal os contaremos todas las novedades de este fascinante campo de trabajo para que aprender sea algo muy sencillo y nunca te quedes con la curiosidadPublication Observatorio Complutense para la Seguridad Clínica Odontológica(2020-06-30) Perea Pérez, Bernardo; Labajo González, Elena; Santiago Sáez, Andrés Sebastián; Albarrán Juan, María ElenaPublication Observatorio Complutense para la Seguridad Clínica Odontológica(2017) Perea Pérez, Bernardo; Santiago Sáez, Andrés Sebastián; Labajo González, Elena; Albarrán Juan, María ElenaPublication “Inhibiting inhibitors”: Preliminary results of a new “DNA extractionamplification” disinhibition technique in critical human samples(Elsevier, 2017) Gomes, Cláudia; Alonso Conde, Alejandro; Marquina Díaz, Domingo; Guardià, Marc; López Matayoshi, César Yoshi; Palomo Díez, Sara; Perea Pérez, Bernardo; Gibaja, Juan F.; Arroyo Pardo, EduardoThe present study focused on the genetic analysis of a presumptive Bronze Age family burial, with at least six skeletons (Plana Castell, Barcelona, Spain). In order to investigate the individuals’ biological affiliation, a molecular study was undertaken, but it was impossible to obtain a positive DNA amplification. The excavation data indicated that the skeletons were buried in an old location used as a dumping ground, being very likely the presence of biological and/or chemical contaminants. To overcome this difficulty, we undertook several modifications both in the extraction as in the amplification protocol, like MgCl2concentration, or the inclusion of Bovine Serum Albumin (BSA). Despite their antiquity, the preliminary results indicate that all samples were effectively inhibited, and for the first time we were able to obtain mtDNA results, specifically, for the Hypervariable mitochondrial region 1. It also allowed us to infer that our protocol performance increased considerable, mainly the amplification modifications. In general, the best results were obtained with MgCl2 0,6 μL (20 mM) and BSA 2 mg/mL per sample. Our result is quite important in a forensic analysis, mainly in cases where corpse/s is/are buried directly in the soil.Publication Observatorio Complutense para la Seguridad Clínica Odontológica(2018-08-30) Perea Pérez, Bernardo; Labajo González, Elena; Santiago Sáez, Andrés Sebastián; Albarrán Juan, María Elena
