Abstract: Bmi-1 expression levels were quantified in plasma of 111 breast cancer patients and in 20 healthy controls by real-time quantitative polymerase chain reaction.Cancer patients with the presence of Bmi-1 mRNA in plasma had higher levels of Bmi-1 expression than healthy controls with Bmi-1 mRNA in plasma. The higher expression levels of Bmi-1 correlated with well-established markers of poor clinical outcome in breast cancer such as positive p53 immunostaining and negative progesterone receptors. Moreover, we described for the first time a statistically significant correlation between Bmi-1 expression in plasma of breast cancer patients and disease-free and overall survival in advanced stages.Our results suggest that levels of Bmi-1 expression may be a surrogate marker of poor prognosis and may become clinically useful as noninvasive diagnostic markers.Early detection of breast cancer can improve survival, and molecular techniques designed to detect metastases or recurrent disease in preclinical or presymptomatic phases may contribute to this strategy. Increased levels of circulating nucleic acids (CNAs) in the plasma or serum of cancer patients have been described [1]. In addition, patients with metastases have higher CNA levels than patients with localized disease [2]. Genetic and epigenetic tumor-associated DNA alterations have been found in plasma of patients with different types of cancer [3-6], which is related to poor prognosis, disease-free survival (DFS), and overall survival (OS) [7-10]. Furthermore, tumor-associated mRNA in plasma is also found in several types of cancer, such as melanoma and breast, colon, and nasopharyngeal carcinomas [11-17]. We reported previously that mRNA-based amplification methods offered higher specificity and sensitivity than DNA in plasma of breast cancer patients [18]. Additionally, an association between tumor mRNA in plasma and pathological parameters compatible with more aggressive tumors was observed [13,15,16]. Therefore, the
Megalithic Constructions Discovered in the Azores, Portugal  [PDF]

Archaeological Discovery (AD) , 2015, DOI: 10.4236/ad.2015.32006
Abstract: The oldest cave art known is of prehistoric origin, dating back to approximately 40,000 years ago in both Asia and Europe. The megalithic constructions in Western Europe and the Mediterranean Region took place mainly in the Neolithic and continued until the Chalcolithic and Bronze Age. The Azores Islands did not seem to have been occupied before the arrival of the Portuguese navigators in the XVth century. Because of that, it was not expected that megalithic structures would be found, or structures that resembled megalithic tombs and rock art in the Azores Islands, geographically located in the Center of the North Atlantic, at 1500 km west of Lisbon (Portugal) and about 1900 km southeast of Newfoundland (Canada). These findings seem to be, historically, a paradox. In a first moment, an oral presentation was made about these findings by the author at the 16th Annual Mediterranean Studies Association Congress, and after that, a field trip took place with the archeologists present at the stated Congress. The perplexity was the dominant conduct of the guests, and some hypotheses that certain archaeologists mentioned were evolved versions which had not been empirically corroborated. Afterwards, new findings were registered at Grota do Medo site, helping to make clear that larger stones had been used to construct structures or monuments. The rock art surrounding the megalithic constructions in the Azores also has similarities with those found in Europe. If these findings belong to the Bronze Age or Iron Age, it can reopen new scientific questions about ancient mid-Atlantic crossings. The present article tries to establish ties among the megalith constructions found in the Azores with those known in Europe.

El valor de la propiedad intelectual en los países en desarrollo
Rozanski,Félix;
Interciencia , 2003,
Abstract: summary the agreement on trade-related aspects of intellectual property rights (trips), in force since 1995, operating under the orbit of the world trade organization (wto), constitutes a global milestone in the development of intellectual property protection under its different forms. this is particularly evident in the latin american countries, where it is necessary to update the norms regulating these rights. as the cooperation between science and the private sector is gaining ground, in comparison with the former model in which public funding of scientific activities was almost exclusive, the adequate protection of intellectual property becomes increasingly relevant also for the scientific sector. scientific findings in order to become patentable require an invention, product or process, that must be new, involve an inventive step, and be capable of industrial application. another form of protection, different and independent of patents is the protection of undisclosed information. public policies that favor intellectual property protection are more related to achieve growth promoting innovation, application and transfer of technology, and quality improvement.
CO-CONSTRUCCIONES EN ESPA?OL: ?COOPERACIóN POR MEDIO DE UNA INTERRUPCIóN?
Burgos,Félix Manuel;
Forma y Función , 2007,
Abstract: this article proposes a review of the co-construction phenomena, understood as the realization of a syntactic unit throughout the contribution of two participants during a conversation. it analyzes 81 cases from spanish casual conversations in cali, colombia . taking into consideration different explanations given as causes of this phenomenon, three variables are proposed to confirm these hypotheses on the studied examples. these variables correspond to: 1. a conversational interaction perspective, where shared cognitive models by the participants are taken into account (lerner, 1991). 2 a syntactic approximation, where the grammatical characteristics of the components are analyzed (ford y thompson, 1996), y 3. a prosodic approach focused in interrupted units (helasvuo, 2004). it is proposed that the theses suggested as causes of the co-construction appearance do have incidence in the studied examples. however, it is shown that in general these units cannot be explained by an isolated cause, but for multiple factors, where syntax and prosody are combined. finally, it is proposed that what at first sight could be considered a conflictive fact of the conversation, an interruption, is a conversational cooperation act.
Demencia
Amarista,Félix José;
Gaceta Médica de Caracas , 2002,
Abstract: al describir las demencias se sigue el siguiente orden: concepto y delimitación nosológica. definición. etiología. clasificación. clínica, evaluación general, diagnóstico. curso y evolución. pronóstico. tratamiento y manejo. prevención. se las clasifica en reversibles e irreversibles, recomendando una evaluación general que incluya: historia clínica meticulosa; exhaustiva anamnesis, cuidadoso examen psiquiátrico, examen clínico completo, incluyendo el neurológico, exámenes paraclínicos, imagenología, electro encefalografía y evaluación psicométrica. se sugiere procurar diagnóstico precoz, que permita modificar el curso, la evolución y el pronóstico de la demencia, ya que el 10 % de ellas puede remitir y en el 30 % se detiene el curso. también se proponen medidas preventivas.
