- Estudio de la flora vascular y la micobiota micorrícica en quemados truferos de Navarra (España)(Comunità Montana dei Monti Martani Serano e Subasio, 2010) Cavero-Remon, R.Y. (Rita Yolanda); Gonzalez-Armada, M. (MB); Miguel-Velasco, A.M. (Ana Maria) deIn spite of the continuous advances in trufficulture there are still many questions about truffle growing, hence the big importance of studying the characteristics of the environment in which it best develops. In this study we have analysed the main ecological characteristics of the vascular flora growing in 24 holm oak brûles. This flora is special, very influenced by the alelopatic substances produced by the mycelium of the fungus, modifying the composition and the characteristics of the flora. As a result, plants grow smaller and with a lower covering. Sometimes they even present changes in their life-cycle. Therophytes typical of disturbed areas are dominant in plantations. Xerophile plants are also common. Besides, the species found in truffiers are proper of shaken, removed and generally sunny, dry and stony places, and many of them weeds. This corroborates the fact that the brûle is a very disturbed environment, both by fungus mycelium as by human intervention. On the other hand, monitoring the mycorrhizae is very important in truffle growing since it allows us to know if the plantations are properly developing or if truffle mycorrhizae have been replaced by other competing fungi. That is why we have carried out a below-ground study of the mycorrhizae appearing in the roots of the same holm-oaks, to check the presence of truffle mycorrhizae and to know if other mycorrhizal fungi are colonizing the roots.
- Actividad trufícola navarra. Cuestiones sin respuesta(Comunità Montana dei Monti Martani Serano e Subasio, 2010) Saez, R. (Raimundo); Miguel-Velasco, A.M. (Ana Maria) deIn Navarra, first plantations were carried out in 1989. The ignorance about truffle and trufficulture was total. Almost everything about truffle was unknown, almost even its existence, but as a consequence of the permanent search for new crops that contribute to diversify and improve agricultural productions of the region, it was decided with great interest to carry out the first plantations, and find information, mainly in France and Italy. Twenty years have passed. Technical and scientific advances have taken place but there are still many doubts. The expectations raised at first have not been reached in many cases. In spite of that, trufficulture is a reality, that covers important areas in those zones suitable for truffle growing, both in Navarra and in Spain, and it is still increasing. In Navarra, with the experience acquired, a few points can be made: • Mycorrhized plant production has evolve positively in Spain, which guarantees one of the most important factors in the reasonable trufficulture, together with land selection, climate or cultivation techniques. • The soil: lands selected for new plantations suit truffle needs. They are bigger plots, which is favourable to the correct management of plantation. • Irrigation: in new trufficulture the irrigation studies and practice have become very necessary. The experimentation in this subject is necessary to cover crop needs. • Spreading and training: promoting trufficulture as a diversification alternative in rural areas has been the aim reached through courses, trips, conferences, festivals, commercial exhibitions, competitions…, which has culminated with the creation of the first Truffle Museum in Spain.

(Caroline A.); Prieto-Frías, C. (Cesár); Coron, E. (Emmanuel); Mayershofer, R. (Rupert); Gay, G. (Gerard); Cesaro, P. (Paola)Background Colon capsule endoscopy (CCE) represents a noninvasive technology that allows visualization of the colon without requiring sedation and air insufflation. A second-generation colon capsule endoscopy system (PillCam Colon 2) (CCE-2) was developed to increase sensitivity for colorectal polyp detection compared with the first-generation system. Objective To assess the feasibility, accuracy, and safety of CCE-2 in a head-to-head comparison with colonoscopy. Design and Setting Prospective, multicenter trial including 8 European sites. Patients This study involved 117 patients (mean age 60 years). Data from 109 patients were analyzed. Intervention CCE-2 was prospectively compared with conventional colonoscopy as the criterion standard for the detection of colorectal polyps that are ≥6 mm or masses in a cohort of patients at average or increased risk of colorectal neoplasia. Colonoscopy was independently performed within 10 hours after capsule ingestion or on the next day. Main Outcome Measurements CCE-2 sensitivity and specificity for detecting patients with polyps ≥6 mm and ≥10 mm were assessed. Capsule-positive but colonoscopy-negative cases were counted as false positive. Capsule excretion rate, level of bowel preparation, and rate of adverse events also were assessed. Results Per-patient CCE-2 sensitivity for polyps ≥6 mm and ≥10 mm was 84% and 88%, with specificities of 64% and 95%, respectively. All 3 invasive carcinomas were detected by CCE-2. The capsule excretion rate was 88% within 10 hours. Overall colon cleanliness for CCE-2 was adequate in 81% of patients. Limitations Not unblinding the CCE-2 results at colonoscopy; heterogenous patient population; nonconsecutive patients. Conclusion In this European, multicenter study, CCE-2 appeared to have a high sensitivity for the detection of clinically relevant polypoid lesions, and it might be considered an adequate tool for colorectal imaging.
- EchoBrush may be superior to standard EUS-guided FNA in the evaluation of cystic lesions of the pancreas(2011) Lozano, M.D. (María Dolores); Álvarez-Cienfuegos, J. (Javier); Subtil, J.C. (José Carlos); Echeveste, J.I. (José I.); Labiano, T. (Tania); Idoate, M.A. (Miguel Ángel); Prieto-Frías, C. (Cesár); Betes, M.T. (María Teresa)BACKGROUND: Cystic lesions of the pancreas are being detected with increasing frequency. Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is one of the most precise methods of diagnosis but still has limited accuracy. A new, through-the-needle cytologic brush system (EchoBrush; Cook Medical, Bloomington, Ind) has been approved for use during EUS evaluation of cystic pancreatic lesions. METHODS: Data from 127 EUS-FNAs of pancreatic cystic lesions were analyzed to compare the cytologic yield of EchoBrush with conventional EUS-FNA. An attending cytopathologist was present on site to assess specimen adequacy in all the cases. Diagnostic yields of both procedures, as well as related adverse events, were recorded. Statistical analysis was performed with the SPSS 15.0 version software (SPSS, Chicago, Ill). RESULTS: A total of 127 cystic lesions of the pancreas from 120 patients (42 men and 78 women, mean age of 62.17 ± 12.17 years) were included in the study. Mean size of lesions was 23.58 ± 21.69 mm. Adequacy of the samples and diagnostic yield were higher using EchoBrush. In 80 (63 %) cases, conventional EUS-FNA was performed, whereas in 47 (37%), we used EchoBrush. Diagnostic material was obtained in 85.1% (40 of 47) of cases using EchoBrush and in 66.3% (53 of 80) with conventional EUS-FNA. (P < .05). There were very few clinically relevant complications related to EUS-FNA and EUS-EchoBrush techniques. CONCLUSIONS: This study suggests that cytological specimens from pancreatic cystic lesions obtained using EchoBrush at the time of EUS are superior to conventional EUS-FNA mainly because of the higher yield of epithelial cells. Larger studies are needed to compare both methods. Cancer (Cancer Cytopathol) 2011. © 2011 American Cancer Society.
- [Reseña] Enrique R. Moros, La vida humana como trascendencia(Eunsa, 2011) Montoya-Camacho, J.M. (Jorge Martín)Llega a nosotros una obra filosófica, cuyo trabajo exploratorio a través de la naturaleza humana, nos permite observar la totalidad del ser desde una perspectiva antropológica. El libro La vida humana como trascendencia de Don Enrique R. Moros es un mapa del hombre, trazado en coordenadas metafísicas: verdad y libertad, fruto de una labor de confrontación con diferentes perspectivas filosóficas que, en la metáfora con la que nos conduce el autor, son aquellos mapas trazados por antiguos exploradores que, de alguna manera, dejaron indicado el norte adecuado para continuar esa labor.
- La teoría fundamentada como metodología de investigación cualitativa en enfermería(Fundación Index, 2010) Lopez-Dicastillo, O. (Olga); Arantzamendi-Solabarrieta, M. (María); Gordo Luis, C. (Cristina); Garcia-Vivar, C. (Cristina)La teoría fundamentada (TF) es un diseño de investigación cualitativa, reconocido a nivel internacional, que ha sido utilizado para desarrollar teorías sobre fenómenos de salud relevantes. Sin embargo, en el ámbito de la enfermería española, la TF ha tenido escasa consideración. Por ello, este artículo se centra en esta metodología cualitativa e ilustra su contribución en la investigación enfermera en España y su utilidad para la Enfermería. También, se presentan brevemente las características metodológicas distintivas de la teoría fundamentada.
- La producción literaria del P. Fabo de María: Una aproximación a la temática americana(Universidad Nacional de Colombia, 2006) Mata-Induráin, C. (Carlos)Este trabajo constituye una aproximación a la presencia de temas americanos en la producción literaria del P. Fabo de María, sacerdote navarro que desarrolló su trabajo misional en Colombia. Se analiza, especialmente, la presencia de los indígenas colombianos (indios guahivos) en sus novelas El doctor Navascués (1904) y Corazón de oro (1914), y también en algunas de sus poesías.
- La traición de las imágenes: mecanismos y estrategias retóricas de la falsificación audiovisual(ZER, 2007) García-Martínez, A.N. (Alberto Nahum)La falsificación audiovisual es una práctica fílmica –con cierto auge desde mediados de los setenta– que simula los modos estéticos y las estrategias de construcción discursiva del género documental. Junto a esta apropiación estilística, el fake también propone una meditación autorreflexiva acerca de los límites de la representación, la credibilidad de la imagen y su carácter potencialmente mentiroso y manipulable. Este artículo se acerca al fenómeno desde una perspectiva histórica para, a continuación, definir los rasgos reflexivos, poéticos y retóricos que lo definen.
