His-topathological staging of liver fibrosis according to the METAVIR scoring system served as the reference. A to-tal of 74 patients underwent ARFI elastography,APRI index,FibroMax and successful liver biopsy. RESULTS:The noninvasive tests had a good correlation with the liver biopsy results. The most powerful test in predicting fibrosis was ARFI elastography. The diagnostic accuracy of ARFI elastography,expressedas area under receiver operating characteristic curve (AUROC) had a validity of 90.2% (95% CI AUROC = 0.831-0.972,P < 0.001) for the diagnosis of significant f ibrosis (F ≥ 2). ARFI sonoelastography predicted even better F3 or F4 fibrosis (AUROC = 0.993,95% CI = 0.979-1).CONCLUSION:ARFI elastography had very good accuracy for the assessment of liver fibrosis and was superior to other noninvasive methods (APRI Index,FibroMax) for staging liver fibrosis.展开更多

Even whether it is preventable, most of the time, there are still very few projects or actions of the local authorities and/or organisations in Romania, due to the lack of information and resources. The suicide prevention line for children and teenagers in Bucharest is presented and evaluated after five years of activity. It may be considered as one example of good practice, since it managed to put together local knowledge, human resources, and social actors. The suicide prevention line for children and teenagers in Bucharest has been established in 2009 by the General Directorate of Social Welfare of Bucharest Municipality, in partnership with the Psychiatric Hospital ＂Prof. dr. Alexandru Obregia＂. The finances are provided by the Welfare Department, the location belongs to the Psychiatric Hospital, and the mental health services are coordinated by a neuro-psychiatrist. There are about 30 volunteers taking the phone calls 24/7. Since 2011, they established the Association of Suicidology.展开更多

A study of the 15,500 letters contained in the Spanish Communist Party＇s [PCE] Historical Archive in Madrid confirms this broadcaster＇s major role in the construction of the mythical symbolic image of the anti-Franco movement. Beyond their function as propaganda instruments of the PCE, La Pirenaica＇s letters reveal the radio station＇s role as a vehicle for the expression of public solidarity and ideological and cultural resistance. La Pirenaica was the voice of the defeated after the Spanish Civil War, and was their confidante and advisor. La Pirenaica＇s letters are the chronicle of the horror that anti-Franco society suffered and endured in Spain.展开更多

The connection between the textile science and electronics, biology or nano-technology has led to the extension of the basic clothing and apparel applications towards multi-functional and technical textiles. Fiber based materials represent proper solution for advanced materials. The authors envisage in this paper to present the work performed in 1NCDTP-Bucharest, for manufacturing surgical gowns for medical applications. The surface of the textile material was plasma nano-technology treated in order to obtain a hydrophobic functionalization. As characteristics of research, different parameters have been used for plasma treatment （gas type, power, time, pressure） and different raw materials （polyester, cotton）. For the investigation of the functionality of raw/finished materials, laboratory instruments have been used in order to highlight the comfort properties obtained. Medical articles have strict regulations for manufacturing due to their usage in surgery units. Dry plasma treatment is an ecological method compared to classical wet finishing of textile materials.展开更多
