The neuropeptide Pth2 modulates social behavior and anxiety in zebrafish

2021

SummaryAnimal behavior is strongly context-dependent and behavioral performance is often modulated by internal state. In particular, different social contexts can alter anxiety levels and modulate social behavior. The vertebrate-specific neuropeptide parathyroid hormone 2 (pth2) is directly regulated by the presence or absence of conspecifics in zebrafish. As its cognate receptor, the parathyroid hormone 2 receptor (pth2r), is widely expressed across the brain, we tested fish lacking the functional Pth2 peptide in several anxiety-related and social paradigms. Rodents lacking PTH2 display increased anxiety-related behavior. Here we show that the propensity to react to sudden stimuli with an …

Hyaline fibromatosis syndrome (juvenile hyaline fibromatosis): whole-body MR findings in two siblings with different subcutaneous nodules distributio…

2017

Abstract: Hyaline fibromatosis syndrome (juvenile hyaline fibromatosis) is a rare, progressive, autosomal recessive disorder whose main hallmark is the deposition of amorphous hyaline material in soft tissues, with an evolutionary course and health impairment. It may present involvement of subcutaneous or periskeletal soft tissue, or may develop as a visceral infiltration entity with poor prognosis. Very few radiological data about this inherited condition have been reported, due to the extreme rarity of disease. We herein present a case of two siblings, affected by different severity of the disease, with different clinical features. They were examined by whole-body MR (WBMR) in order to as…

Electron microscopic studies on skin and lymphocytes in early juvenile neuronal ceroid-lipofuscinosis.

1987

Skin and lymphocytes of three patients with early juvenile neuronal ceroid-lipofuscinosis (NCL) were ultras trueturally investigated. Fingerprint profiles (FPP), isolated and I or mixed with curvilinear profiles (CLP), in various dermal cells and large, usually single lipopigments delineated by a trilaminar membrane and filled with a granular matrix, FPP and occasionally lipid droplets in lymphocytes were observed in all three patients. Characteristic lipopigments in lymphocytes are an important feature to differentiate between early juvenile NCL and late infantile and juvenile NCL.

Nonepithelial skin tumors with multinucleated giant cells

2013

Recognition of the different types of multinucleated giant cells in neoplastic and pseudotumoral lesions of the skin may be helpful in the differential diagnosis of these tumors. In this review, we will analyze the different types of multinucleated giant cells that can be found in nonepithelial cutaneous tumors and, more importantly, the clinicopathological context in which they are found. Touton giant cells are typically present in juvenile xanthogranuloma, necrobiotic xanthogranuloma, and some subtypes of xanthomas. Giant cells with a ground glass appearance are typically present in the solitary reticulohistiocytoma and multicentric reticulohistiocytosis. Osteoclast-like cells are found i…

Atypical presentation of anti-N-methyl-D-aspartate receptor encephalitis: two case reports

2017

Abstract Background Anti-N-methyl-D-aspartate receptor encephalitis is a rare autoimmune disease characterized by severe neurological and psychiatric symptoms and a difficult diagnosis. The disease is often secondary to a neoplastic lesion, seldom diagnosed years later. Psychiatric symptoms are prevalent in adults; neurologic symptoms are more evident in children, who typically present primarily with neurological symptoms. To the best of our knowledge, the association with juvenile idiopathic arthritis has not been described. Case presentation We report the cases of two caucasian girls with an atypical presentation. The first patient was an 8-year-old girl with normal psychomotor developmen…

Análisis de las políticas de seguridad ciudadana en El Salvador y su impacto en el incremento de la violencia

2021

Este artículo analiza las políticas de seguridad ciudadana que se han implementado en ElSalvador para combatir a las pandillas. El estudio hace un repaso por los cuatro distintosgobiernos que de 2003 a 2019 han intentado, sin éxito, reducir los altos niveles deviolencia. El artículo indaga en cómo estas políticas han permitido el fortalecimiento delas pandillas, el debilitamiento de la institucionalidad y, principalmente, elrecrudecimiento de la violencia expresada en la tasa de homicidios, que ha hecho de ElSalvador uno de los países más violentos del mundo. Por otra parte, también se hace unabreve exposición sobre el futuro de la política de seguridad ciudadana del gobierno de  Nayib Buke…

Mercado de trabajo juvenil y políticas de empleo

1992

El paro juvenil es una de las características distintivas de la nueva situación que conocen muchas economías industrializadas desde 1973. En este articulo se reflexiona sobre las causas y consecuencias de la peor situación que soporta el colectivo juvenil en el mercado de trabajo. Las causas ha que buscarlar más en las condiciones generales de la economía del mercado de trabajo que en las características individuales de los jóvenes. Las consecuencias repercuten sobre el concepto mismo de juventud y sobre los procesos de inserción de las nuevas generaciones en la sociedad. Finalmente, se reflexiona también sobre la filosofía que sustenta la política de empleo juvenil. L'atur juvenil és una d…

Factor Structure and Construct Validity of the Youth Psychopathic Traits Inventory and Its Shorten Version in Chinese Detained Boys

2019

The Youth Psychopathic Traits Inventory (YPI) was designed to assess psychopathic traits in adolescents. However, there exists limited evidence for the factor structure and psychometric properties of the YPI when used with Chinese detained juveniles. The present study aimed to examine the factor structure and construct validity of the YPI and its shortened version (YPI-S) in a sample of 607 Chinese 14- to 22-year-old detained boys (M = 17.15, SD = 1.09). Confirmatory factor analyses revealed a bifactor model which best fit the data at the subscale level for the YPI, and at the item level for the YPI-S. The internal consistency of the YPI and YPI-S scores ranged from marginal to good. Both t…

Evaluación del riesgo de reincidencia en menores infractores: herramientas para la mejora de estrategias reeducativas en España

2016

El presente estudio trata de conocer las herramientas que actualmente se utilizan en el ámbito judicial en menores para evaluar el riesgo de reincidencia en España. Para abordar el trabajo se ha realizado una revisión de la literatura existente y se ha llevado a cabo un análisis comparativo de los instrumentos con mayor ascendencia, que permiten identificar dicho riesgo. Tras el análisis, y desde la perspectiva del Trabajo Social, se destaca la herramienta SAVRY puesto que es una herramienta que abarca una gran cantidad de factores y permite el desarrollo de actuaciones efectivas potenciando conductas prosociales que reduzcan el riesgo de de- lincuencia futura. El conocimiento de estas herr…

Vinculación entre la vulnerabilidad y la exclusión social y las trayectorias delictivas. Un estudio de asociación

2017

RESUMEN Este estudio tiene por objeto identificar la relación existente entre las trayectorias delictivas y los factores de vulnerabilidad y exclusión social en adolescentes en conflicto con la ley. Para ello se analizan 281 expedientes de adolescentes en conflicto con la ley de la ciudad de València y se generan 3 trayectorias delictivas: inicial, moderada y consolidada, que se asocian a indicadores de vulnerabilidad y exclusión social. Se muestran evidencias empíricas de su relación. Las trayectorias delictivas y los factores de vulnerabilidad y exclusión social se hallan plenamente conectados, entrelazados y superpuestos. La acumulación de factores de vulnerabilidad y exclusión social en…
