INTRODUCCIÓN: Los aneurismas disecantes de la arteria basilar tienen un curso clínico impredecible que, eventualmente, evoluciona a un accidente cerebrovascular hemorrágico o isquémico grave. Por otro lado, su abordaje terapéutico es controvertido y no existen líneas claras de tratamiento. CASO CLÍNICO: Presentamos el caso de una mujer de 28 años con un infarto del tallo cerebral secundario a aneurisma disecante de la arteria basilar, tratado exitosamente con dispositivo endoluminal redireccionador de flujo (FRED). CONCLUSIÓN: El tratamiento endovascular con FRED de los aneurismas disecantes parece ofrecer ventajas sobre las técnicas quirúrgicas abiertas y stents tradicionales, en casos seleccionados.

This article reports the outcomes of the research project about leadership in students and graduates, conducted by the Business Administration Programme at Minuto de Dios University Corporation, Uniminuto main campus. The research is generated from a study prepared by a consulting company, in which only 9% of the of the programme graduates are recognised for having leadership skills. The objective is to identify the role of leadership as a curriculum pillar in the professional development of students, graduates, and programme teachers. In addition, institutional leadership and its contribution to the professional and employment development of students and graduates is investigated. The research methodology is a qualitative and descriptive analysis. The results show that students and graduates do not consider themselves leaders and the contribution of curriculum courses to strengthen this skill is not evident. A reform of the curriculum is recommended with themes and activities that inspire and motivate this complex task.

In this research, a simple application of carbon nanotubes to filtrate water is explained. Nanomembranes were assembled using Mwcnt and cotton to create a mesh and fiber support to remove pollutants and meet the World Health Organization (WHO) parameters for drinking water. After the nanofiltration process the following results were obtained: Escherichia Coli was reduced from 6.8 per 100 ml to 2.0 per 100 ml, Turbidity obtained after nanofiltration was reduced from 4.04 to 0.23 mg/l; Magnesium content was reduced from 93.14 mg/l to 13.62 mg/l, total hardness was reduced from 450 mg/l to 132 mg/l, the color diminished from 58 units to 1.0 units, Ph got reduced from 6.87 to 6.44. The results show that the quality of water can be improved using multi wall carbon nanotubes to meet drinking water requirements. In addition, electric current was used through membranes to create electro separation of pollutants and let filtrated water to pass. The results also showed water with fewer pollutants and less turbidity after the nano filtration process. This is an approach in the use of nanotechnology for waste water treatment and increase the access to drinking water to more people around the World. This research was performed at School of mechanical engineering and engineering research center from University of San Carlos of Guatemala.
