Enfermedad de Jacob asociada con el síndrome de disfunción de la articulación temporomandibular: presentación de un caso

La enfermedad de Jacob se describe como una entidad infrecuente en la cual se establece una formación articular sinovial entre una apófisis coronoide mandibular elongada y el hueso malar homolateral. El Síndrome de disfunción de la articulación temporomandibular (ATM) ha sido postulado como posible factor etiológico del alargamiento este proceso coronoideo. Presentamos el caso de una mujer de 23 años con un desplazamiento discal de ATM de larga evolución y limitación de la apertura oral, que desarrolló una asimetría malar progresiva. La paciente fue sometida a tratamiento quirúrgico mediante una coronoidectomía intraoral y una artroscopia de la ATM homolateral en el mismo acto operatorio. El diagnóstico histológico de la apófisis coronoide examinada fue de exóstosis óseo-cartilaginosa con presencia de fibrocartílago articular en dicha formación. A pesar de la baja prevalencia de esta patología, debe ser considerada como un posible diagnóstico en aquellos pacientes con limitación progresiva de la apertura oral de larga evolución, si bien en ocasiones puede acompañarse de una disfunción articular crónica concomitante como posible causa de la misma.Jacob´s disease is regarded a rare condition in which a joint formation is established between an enlarged mandibular coronoid process and the inner aspect of the zygomatic body. Chronic temporomandibular joint (TMJ) disk displacement has been proposed as etiological factor of coronoid process enlargement. We present a 23-year-old woman with long-standing TMJ dysfunction and restricted interincisal opening, who developed a progressive zygomatic assymetry. The patient underwent treatment by intraoral coronoidectomy and homolateral TMJ arthroscopy in the same surgery. The histopathological diagnosis of the coronoid sample was cartilage-capped exostoses with presence of articular fibrous cartilage. Although the low prevalence of this entity, it should be considered as a possible diagnosis in patients with progressive limitation of mouth opening, although a TMJ syndrome may be present as a cause of this entity

Level densities of transitional Sm nuclei

Experimentally determined level densities of the transitional isotopes 148, 149, 150, 152Sm at excitation energies below and around the neutron binding energy are compared with microcanonical calculations based on a Monte Carlo approach to noncollective level densities, folded with a collective enhancement estimated in the frame of the interacting boson model (IBM). The IBM parameters are adjusted so as to reproduce the low-lying discrete levels of both parities, with the exception of the odd-mass nucleus, 149Sm, where complete decoupling of the unpaired neutron from the core is assumed

Contribution to study of Creole Cuban Pig breed

The Creole pig is the only authoctonous Cuban pig breed and, at present time, it is specially important for the economy of the country. This breed is mainly located in the oriental areas, generally linked to family farms using natural resources and agricultural by-products. This paper study its morphological (twelve continuous variables and seven zoometric index) characteristics on a random sample formed by 100 adult animals belonging to both sexes from several geographical localisations in the Granma provincia. Also we have studied four phanaeroptical variables using a sample formed by 620 animals. The pig shows a sub-concave front profile pig, with sublonginlineal proportions, backline ascendant, long croup and with coat colours generally black, some animals are hairless, while other are half-haired.El Cerdo Criollo Cubano, el único porcino autóctono de Cuba, es especialmente importante para la actual situación económica del país. Se localiza generalmente en la zona oriental del país, en explotaciones familiares aprovechando los recursos naturales y subproductos agrícolas. Se estudia la caracterización morfológica (doce variables morfológicas y siete índices zoométricos) de la población utilizando una muestra aleatoria formada por 100 animales de ambas sexos de diferentes localizaciones geográficas de la provincia de Granma. Además se aborda la caracterización faneróptica utilizando cuatro variables en una muestra de 620 ejemplares. Se trata de un cerdo de perfil craneal subcóncavo, de proporciones sublongilíneas, línea dorsolumbar ascendente, grupa larga y derribada, y de capas generalmente negras, con unos animales lampiños y otros entrepelados

Obstructive Sleep Apnoea Syndrome, Endothelial Function and Markers of Endothelialization. Changes after CPAP

STUDY OBJECTIVES: This study tries to assess the endothelial function in vivo using flow-mediated dilatation (FMD) and several biomarkers of endothelium formation/restoration and damage in patients with obstructive sleep apnoea (OSA) syndrome at baseline and after three months with CPAP therapy. DESIGN: Observational study, before and after CPAP therapy. SETTING AND PATIENTS: We studied 30 patients with apnoea/hypopnoea index (AHI) >15/h that were compared with themselves after three months of CPAP therapy. FMD was assessed non-invasively in vivo using the Laser-Doppler flowmetry. Circulating cell-free DNA (cf-DNA) and microparticles (MPs) were measured as markers of endothelial damage and the vascular endothelial growth factor (VEGF) was determined as a marker of endothelial restoration process. MEASUREMENTS AND RESULTS: After three month with CPAP, FMD significantly increased (1072.26 ± 483.21 vs. 1604.38 ± 915.69 PU, p< 0.005) cf-DNA and MPs significantly decreased (187.93 ± 115.81 vs. 121.28 ± 78.98 pg/ml, p<0.01, and 69.60 ± 62.60 vs. 39.82 ± 22.14 U/μL, p<0.05, respectively) and VEGF levels increased (585.02 ± 246.06 vs. 641.11 ± 212.69 pg/ml, p<0.05). These changes were higher in patients with more severe disease. There was a relationship between markers of damage (r = -0.53, p<0.005) but not between markers of damage and restoration, thus suggesting that both types of markers should be measured together. CONCLUSIONS: CPAP therapy improves FMD. This improvement may be related to an increase of endothelial restoration process and a decrease of endothelial damage

Perfil fenólico de aceites de oliva vírgenes obtenidos de selecciones avanzadas en un programa de mejora

The evaluation of the phenolic composition in advanced selections in breeding programs constitutes the first approach for selecting genotypes with improved olive oil quality. In this work, the influence of genotype and ripening index on the phenolic profile of olive oils from advanced selections in comparison to their genitors was studied. Fruit samples were collected in genotypes from crosses between ‘Arbequina’ × ‘Picual’, ‘Picual’ × ‘Arbequina’ and ‘Frantoio’ × ‘Picual’ at five dates from 1st October to 26th November 2009. Characterization of the phenolic profile was performed by liquid–liquid extraction with 60:40 (v/v) methanol–water and subsequent chromatographic analysis with absorption and fluorescence detection in a sequential configuration. A dual effect of genotype and fruit ripening on the phenolic profile has been observed with more pronounced genetic influence in both total (34.73% and 20.45%, respectively) and individual phenols (16.99% to 49.25% and 1.58% to 23.77%, respectively). A higher degree of variability between genotypes at early ripening stages was also observed (p&lt;0.05). The obtained results also allow identification of selections with high content of total and individual phenols. These results suggest a strategy based on early harvesting of fruits (at the first three ripening indexes) for better comparison and selection of genotypes in further crosses in olive breeding programs aiming at improving the quality of virgin olive oil.La evaluaci&oacute;n de la composici&oacute;n fenolica en selecciones avanzadas en programas de mejora constituye el primer paso para la selecci&oacute;n de genotipos cuyos aceites son de mejor calidad. Se ha estudiado la influencia del genotipo y del &iacute;ndice de madurez en el perfil fen&oacute;lico del aceite de oliva de selecciones avanzadas en comparaci&oacute;n con sus genitores. Se recogieron muestras de genotipos obtenidos de cruzamientos entre 'Arbequina' &times; 'Picual', 'Picual' &times; 'Arbequina' y 'Frantoio' &times; 'Picual' en cinco fechas entre el 1 de octubre y el 26 noviembre de 2009. Se realiz&oacute; la caracterizaci&oacute;n del perfil fen&oacute;lico por extracci&oacute;n l&iacute;quido&ndash;l&iacute;quido con metanol&ndash;agua al 60:40 (v/v) seguido de un an&aacute;lisis cromatogr&aacute;fico con detecci&oacute;n por absorci&oacute;n y fluorescencia en una configuraci&oacute;n secuencial. Los resultados obtenidos mostraron un mayor grado de variabilidad entre genotipos en las primeras etapas de maduraci&oacute;n de los frutos (p&lt;0.05), as&iacute; como el efecto de la madurez de los frutos y del genotipo en el perfil fen&oacute;lico, con una influencia gen&eacute;tica m&aacute;s pronunciada tanto para fenoles totales (34.73% and 20.45%, respectivamente) como individuales (entre 16.99% y 49.25% y entre 1.58% y 23.77%, respectivamente). Los resultados obtenidos han permitido la identificaci&oacute;n de selecciones con alto contenido en fenoles totales e individuales. Ambos resultados sugieren una estrategia basada en la evaluaci&oacute;n de los fenoles totales e individuales en las primeras etapas de la maduraci&oacute;n para comparar y seleccionar genotipos en programas de mejora por cruzamiento encaminados a mejorar la calidad del aceite de oliva virgen

Zootechnical evolution in the spanish merino in early times and future

The Spanish native Merino sheep breed is perhaps the most important of the Spanish zootechnical successes. The repercussion of this breed has evolved not only the animal production but also other aspects such as laws, language and the history of this country. Over the years the Spanish Merinos have found several difficulties that have produced many oscillations in their census. Among them, undoubtedly the most significative has been the falling down of the wool price in the sixties, which made a change in the productive objectives planned for the breed. Recently the Merinos Association of breeders have developed a programme of selection and improvement, presently in a great level. The philosophy of this programme is based on the improvement of meat characteristics with the selection of direct and maternal additive genotypes, maintaining the morphological characteristics and the rusticity of the breed. In this communication the master lines to design a competitive future for this breed are described.La raza ovina Merino Autóctono Español es, quizás, el más emblemático de los logros de la zootecnia española, es una raza cuya importancia ha arraigado no sólo en la producción animal sino incluso en otros aspectos como la legislación, el léxico y la historia de nuestro país. En el transcurrir de los años diferentes dificultades le han inducido a significativas oscilaciones censales, de entre ellas la más grave ha sido sin duda la caída de los precios de la lana en la década de los sesenta que obligó a un cambio de planteamientos en los objetivos productivos de esta raza. Fue necesaria una transformación urgente de unas poblaciones de doble función lana-carne a otras donde destacaran más los aspectos cárnicos. Recientemente la Asociación de Criadores de Ganado Merino ha implementado un Programa de Selección y Mejora que ya se encuentra a un gran nivel de desarrollo, y cuya filosofía se basa en la mejora de los caracteres cárnicos de esta raza a través de la selección del genotipo directo y materno, manteniendo las características raciales y rusticidad propias de la raza. En esta comunicación también se trazan las líneas para diseñar un futuro competitivo para la raza Merina

Effect of research impact on emerging camel husbandry, welfare and social-related awareness

The lack of applied scientific research on camels, despite them being recognized as production animals, compels the reorganization of emerging camel breeding systems with the aim of achieving successful camel welfare management strategies all over the world. Relevant and properly-framed research widely impacts dissemination of scientific contents and drives public willingness to enhance ethically acceptable conditions for domestic animals. Consumer perception of this livestock industry will improve and high-quality products will be obtained. This paper draws on bibliometric indicators as promoting factors for camel-related research advances, tracing historical scientific publications indexed in ScienceDirect directory from 1880–2019. Camel as a species did not affect Journal Citation Reports (JCR) impact (p &gt; 0.05) despite the journal, author number, corresponding author origin, discipline and publication year affecting it (p &lt; 0.001). Countries with traditionally well-established camel farming are also responsible for the papers with the highest academic impact. However, camel research advances may have only locally and partially influenced welfare related laws, so intentional harming acts and basic needs neglect may persist in these species. A sustainable camel industry requires those involved in camel research to influence business stakeholders and animal welfare advocacies by highlighting the benefits of camel wellbeing promotion, co-innovation partnership establishment and urgent enhancement of policy reform
