Donne altrove. Viaggi, scrittura periodica e identità nell'Ottocento inglese
2015
The book focuses on the usage and publication of travelogues by 19th century women travellers to the colonies of the Empire as tools for spreading a new female identity based on courage, strenght, adventurous attitudes, in brief, based on all those features on which male identity had governed the economic, social, political and cultural areas, and last but not least, suffocated the so called 'fragile' gender. the travelogue, that is the writing of a a non fictional travel experience by women, to and in place such as the colonies, considered as the uncivilised and dangerous side of the Empire gave women the possibility to develop and perform their own selves as authoritative, mobile and powe…
Splenic Littoral Cell Hemangioendothelioma in a Patient With Crohn's Disease Previously Treated With Immunomodulators and Anti-TNF Agents: A Rare Tum…
2011
Th e risk of malignancy in Crohn ’ s disease (CD) has been well described. Moreover, immunomodulators, uch as azathioprine (AZA) and 6-mercaptopurine (6-MP), and biological agents, such as infl iximab and adalimumab, may promote carcinogenesis ( 1 – 3 ). Splenic littoral cell tumors are recently described tumors of vascular origin composed of endothelial cells, with typical microscopic and immunohistochemical features of splenic sinus lining cells ( 4 ). Clinical findings are not specific, and outcome is unpredictable but usually benign, although a few cases with a malignant behavior have been reported ( 5,6 ). We report a 58-year-old Caucasian man with a long history of ileocolonic CD.
Imaginaire colonial et représentation visuelle des populations noire africaines. Le cas de la Guinée espagnole (1880-1968)
2021
Cet article est la reprise du texte introductif de l’ouvrage accompagnant l’exposition « Let’s bring blacks home ! Imaginación colonial y formas de aproximación gráfica de los negros de África (1880-1968) », qui se tint au Centre culturel La Nau de l’université de Valence (Espagne), en février-mars 2020 [1]. Le propos de l’exposition et de l’ouvrage consistait à analyser certaines formes d’appréhension iconographique des populations noires africaines dans le contexte de la culture de masse, notamment le cas, peu connu, de la Guinée espagnole, l’actuelle Guinée équatoriale. L’exposition était découpée en cinq sections illustrant (à travers des objets de collections publiques et privées, cart…
Anatomía quirúrgica de la vascularización mesocólica aplicada a la colectomía oncológica mínimamente invasiva
2021
La evolución de la cirugía oncológica en el cáncer de colon plantea la necesidad de resecciones más amplias y radicales, que pueden aumentar el riesgo de complicaciones intraoperatorias, principalmente vasculares. El conocimiento detallado de la anatomía vascular del colon y sus posibles variaciones se ha vuelto crucial para el cirujano laparoscopista. El objetivo principal de este trabajo es analizar la variabilidad en la vascularización del colon derecho y del ángulo esplénico, así como su aplicabilidad en la cirugía mínimamente invasiva del cáncer de colon. MATERIAL Y MÉTODOS Estudio anatómico en 27 cadáveres humanos dividido en dos apartados: - Estudio anatómico del colon derecho: se ha…
Diversidad liquénica asociada a fenómenos post-incendio en los alcornocales valenciano-castellonenses.
2001
FOS, S., CALATAYUD, A. & BARRENO, E. 2001. Lichen diversity associated with post-fire colonization in the Valenciano-castellonense cork-oak forests. Bot. Complutensis 25: 103113. 103 Simón Fos et al. Diversidad liquénica asociada a fenómenos post-incendio... The post-fire colonization of the burned barks of cork-oaks (Quercus suber L.) by epiphytic lichens affected by fire episodes has been studied in different areas of the Valenciano-castellonense cork-oak forests (Asplenio onopteridis-Querco suberis sigmetum). These forests, which have been affected by fires of different intensity, are located in Espadán and Calderona mountains and in the Desierto de Las Palmas and differ with respect…
Validación de un modelo in situ de predicción de absorción en colon. Aplicación al desarrollo de formas de liberación controlada.
2017
El intestino delgado presenta las características idóneas (anatómicas, fisiológicas y fisicoquímicas) para llevar a cabo la absorción de xenobióticos, por lo que es considerado el órgano por excelencia para realizar dicho proceso. El colon, por el contrario, no se ha tenido en cuenta tradicionalmente como órgano destinado a la absorción. Por este motivo, existe una escasez de estudios científicos relacionados con la absorción de moléculas en colon. Sin embargo, en las últimas décadas, el auge de las fórmulas de liberación controlada ha provocado que los estudios de absorción de moléculas en el colon ganen importancia, ya que para este tipo de formulaciones farmacéuticas el tramo distal del …
Identification and expansion of human colon-cancer-initiating cells
2007
Colon carcinoma is the second most common cause of death from cancer. The isolation and characterization of tumorigenic colon cancer cells may help to devise novel diagnostic and therapeutic procedures. Although there is increasing evidence that a rare population of undifferentiated cells is responsible for tumour formation and maintenance, this has not been explored for colorectal cancer. Here, we show that tumorigenic cells in colon cancer are included in the high-density CD133+ population, which accounts for about 2.5% of the tumour cells. Subcutaneous injection of colon cancer CD133+ cells readily reproduced the original tumour in immunodeficient mice, whereas CD133- cells did not form …
Abundance of narG , nirS , nirK , and nosZ Genes of Denitrifying Bacteria during Primary Successions of a Glacier Foreland
2006
ABSTRACT Quantitative PCR of denitrification genes encoding the nitrate, nitrite, and nitrous oxide reductases was used to study denitrifiers across a glacier foreland. Environmental samples collected at different distances from a receding glacier contained amounts of 16S rRNA target molecules ranging from 4.9 × 10 5 to 8.9 × 10 5 copies per nanogram of DNA but smaller amounts of narG , nirK , and nosZ target molecules. Thus, numbers of narG , nirK , nirS , and nosZ copies per nanogram of DNA ranged from 2.1 × 10 3 to 2.6 × 10 4 , 7.4 × 10 2 to 1.4 × 10 3 , 2.5 × 10 2 to 6.4 × 10 3 , and 1.2 × 10 3 to 5.5 × 10 3 , respectively. The densities of 16S rRNA genes per gram of soil increased with…
Entre Trapani et Tunis. De la période du Risorgimento à la fin du Protectorat français: parcours de travailleurs et d’entrepreneurs au-delà du Canal …
2019
Sin dai tempi più antichi, il Canale di Sicilia e la città di Trapani hanno costituito un ponte naturale fra il Maghreb e la Sicilia. Il saggio mette a sistema alcuni studi sugli architetti ed imprenditori di origine trapanese che emigrarono in Tunisia fra il XVIII e XIX secolo e ne propone una lettura inedita. Il fil rouge che lega Giuseppe Abita, la famiglia di imprenditori Canino e Domenico Basciano riguarda sia la loro provenienza dalla città siciliana, ma soprattutto l'importante contributo che essi hanno trasferito nell'architettura del periodo coloniale e post-coloniale francese nel Maghreb.
