LA VIOLENCIA CONTRA LAS MUJERES COMO PRUEBA DE MASCULINIDAD. REFLEXIONES SOCIO-CRIMINOLÓGICAS
2021
Research typically employs essentialist and static representations of masculinity to deal with of male violence against women. Masculinity is thereby linked to pre-social phenomena, naturalized categories, and to identity configurations that are defined as dangerous, due to biological, ethno-racial or class characteristics/configurations. Conversely, a sociologically oriented critical criminology concerned in the relationship between masculinity and crime should interrogate the ways in which, at the social level, committing a deviant or criminal conduct is intertwined with achieving male status and power. We will thus re-read the issue of violence against women as a male problem, that is, a…
Optimización y caracterización de la calidad de imagen en tomografía por emisión de positrones
2012
Las distintas modalidades de la Imagen Médica tienen un mismo objetivo, obtener una imagen que represente un parámetro físico de interés del interior del paciente. Y para todas ellas la calidad final de la imagen médica viene determinada por cómo de bien se represente la verdadera distribución espacial que el parámetro físico tiene en el interior paciente. Para poder obtener una imagen médica de calidad es necesario conocer en profundidad la física implicada en el proceso de medida. El conocimiento de los fundamentos físicos en los que se basa cada una de las técnicas de Imagen Médica nos permite conocer los factores que van a contribuir a la degradación de las magnitudes que definen la cal…
SOLID LIPID NANOPARTICLES FOR APPLICATIONS IN GENE THERAPY: A REVIEW OF THE STATE OF THE ART
2010
Importance of the field. Gene therapy represents a new paradigm in the prevention and treatment of many inherited and acquired diseases, including genetic disorders, such as cystic fibrosis, haemophilia and many somatic diseases, such as tumours, neurodegenerative diseases and viral infections, such as AIDS. Areas covered in this review. Among a large array of non-viral transfection agents used for in-vitro applications, cationic SLNs are the topic of this review, being recently proposed as an alternative carrier for DNA delivery, due to many technological advantages such as large-scale production from substances generally recognized as safe, good storage stability and possibility of steam …
Association between urticaria and nematode infections
2018
Background The association between parasites and urticaria was first suggested in the last century. A wide range, 0-75.4%, of the prevalence of parasitic infection has been reported with chronic urticaria (CU). Moreover, urticaria may be detected in patients with parasitosis. Nematodes are a type of helminth that infect hundreds of millions of people throughout the world. Objective The aim of this work was to collect and review the published studies and cases of urticaria associated with nematode infections. Methods A search of scientific literature data bases from January 1960 until May 2017 was carried out. Results Numerous nematode infections have been associated with urticaria and/or an…

Halloysite nanotubes as a carrier of cornelian cherry (Cornus mas L.) bioactives
2020
Abstract Cornelian cherry fruit extract rich in anthocyanins and iridoids was encapsulated in the halloysite nanotubes in order to obtain a stable nanoscale system for better delivery and prolonged release of bioactive constituents. The cyclic vacuum technique was used for halloysite nanotubes-cornelian cherry composite preparation and the loading of 8.5 wt% was achieved. Pure cornelian cherry extract exhibited antiproliferative effect on HT-29, MCF7, and MRC-5 cells, pristine halloysite nanotubes affected the growth of MCF7 cells, while halloysite nanotubes-cornelian cherry composites demonstrated proliferative activity in all tested cells. The sustained release of anthocyanins was achieve…
The Sulawesi Thrush ( Cataponera turdoides ; Aves: Passeriformes) belongs to the genus Turdus
2021
The Asian and Australo-Papuan faunas meet and intermix across the islands of Wallacea. Untangling the origins and relationships of the species inhabiting these archipelagos is an ongoing project that has lasted for well over a century. In recent years, molecular phylogenetic studies have made considerable progress in clarifying the affinities of enigmatic Wallacean taxa, but taxonomic riddles remain, even in groups as well studied as birds. Such is the case with Sulawesi Thrush Cataponera turdoides, a scarce and elusive montane songbird whose taxonomic placement has remained controversial since its description. To determine the evolutionary relationships of this monotypic genus, we obtained…
Doing gender and sexuality intersectionally in multimodal social media practices
2021
The chapter focuses on how members in participatory cultures engage in everyday, informal, and interest-driven social and discursive practices primarily on social media but also in ways that relate to the material and physical contexts of their lives. We show how social actors operating in these sites construct gender and sexuality intersectionally and multimodally. We argue that gender and sexuality are always constructed at intersections with other identity categories. With respect to both digital and physical participatory activities, multisemioticity is, in turn, necessary as an analytic perspective: it allows the investigation of how participants routinely draw on and deploy a range of…
Molecular systematics and phytochemistry of Rehmannia (Scrophulariaceae)
2007
Abstract The relationships between the six known species of Rehmannia were investigated. With regard to the content of iridoid glucosides, caffeoyl phenylethanoid glycosides (CPGs) and ionone glucosides, no conclusions could be drawn. Phylogenetic analysis of DNA sequence data (ITS region, trnL-F region and rps 16 intron) reveal a well-resolved topology in which Rehmannia glutinosa and Rehmannia solanifolia and Rehmannia piasezkii and Rehmannia elata are well-supported species pairs. Rehmannia chingii is sister to the rest of the genus, which is congruent with its distribution distant to the other species of the genus.
Emerging Raf inhibitors
2009
The Raf/MAPK kinase/extracellular-signal-regulated kinase pathway is often activated by genetic alterations in upstream signaling molecules. An integral component of this pathway, BRAF, is also activated by mutation, especially in melanoma and thyroid cancers. The Raf/MAPK kinase/extracellular-signal-regulated kinase pathway has profound effects on proliferative, apoptotic and differentiation pathways as well as the sensitivity and resistance to chemotherapeutic drugs.This review discusses targeting of Raf which could control abnormal proliferation in cancer and other proliferative diseases. The important roles that genetics plays in the response of patients to Raf inhibitors is also evalua…
