    The human immunodeficiency virus type I (HIV-1) is known worldwide for the damage that can cause in the immune system to people who are infected, affecting CD4 T lymphocytes, either for unprotected sexual activity, Drug addiction, among others. This disease can have different characteristics, depending on the age, sex, race and / or geographic location of the patient. In Colombia this disease is characterized by being ruinous and catastrophic of high cost as defined by decree 2699 of 2007 in Article 1. The prevalence of HIV-1 in Colombia as dictated by the bulletin of the year2015 Current situation the adjusted prevalence was 0.13 %. The incidence that was presented and reported in the bulletin of the year 2015 is 15.4 per 100,000 inhabitants. There are antiretroviral drug groups, one of which is protease inhibitors (PIs), blocking an HIV enzyme called protease. When the protease is blocked, the two drugs in combination Lopinavir-Ritonavir And can reduce the concentration of HIV in the body. Lopinavir is an HIV-1 protease inhibitor, Ritonavir inhibits the cytochrome P450-mediated metabolism of Lopinavir, thus providing increased plasma levels of Lopinavir. The protease enzyme functions as a chemical scissors cutting the raw material Of HIV, ie large viral proteins in small pieces or new particles of HIV that are necessary to build a new virus, protease inhibitors interfere with such scissors, preventing virus replication, creating non-infectious virions. When the study of the use of Lopinavir-Ritonavir drugs was carried out, it was possible to conclude that the highest rate of DDD use occurs in the age group of 35 to 54 years, evidencing a relevance in pharmacotherapy for the treatment of HIV-1 From the point of view of dosage ranges and treatment regimens, observing the complete and correct use of the management guides for patients and is being correctly prescribed, thus achieving a rational use of these drugs. Since this age has a better progression of the treatment, the costs of the therapy are assumed, since also in that age range patients have a better adherence to the treatment with a greater attendance of patients in the department of Bogotá for the year 2013El virus de la inmunodeficiencia humana tipo I (VIH-1) es conocido mundialmente por los daños que puede llegar a causar en el sistema inmune a las personas que se encuentran infectadas, afectando los linfocitos T CD4, ya sea por actividad sexual sin protección, drogadicción, entre otras. Esta enfermedad puede tener diferentes características, dependiendo la edad, el sexo, la raza y/o localización geográfica del paciente. En Colombia esta enfermedad se caracteriza por ser ruinosa y catastrófica de alto costo como lo define el decreto 2699 de 2007 en el Artículo 1. La prevalencia del VIH-1 en Colombia según lo dicta el boletín del año 2015 Situación actual la prevalencia ajustada fue del 0.13%. La incidencia que se presentó y reportó en el boletín del año 2015 es de 15.4 por cada 100.000 habitantes. Para el tratamiento de esta enfermedad existen los grupos de fármacos antirretrovirales, en donde uno de ellos son los inhibidores de la proteasa (IP) bloqueando una enzima del VIH-1 llamada proteasa, al bloquear la proteasa, los dos medicamentos en combinación Lopinavir-Ritonavir evitan la multiplicación del VIH-1 y pueden reducir la concentración de ese virus en el cuerpo. El Lopinavir es un inhibidor de la proteasa del VIH-1, el Ritonavir inhibe el metabolismo de Lopinavir mediado por el citocromo P450, proporcionando de este modo incremento en los niveles plasmático de Lopinavir La enzima proteasa funciona como una tijera química que corta la materia prima del VIH-1, es decir las grandes proteínas virales en pequeños trozos o nuevas partículas de VIH-1 que son necesarias para construir un virus nuevo, los inhibidores de la proteasa interfieren con dichas tijeras, evitando la replicación del virus, creando viriones no infecciosos. Al realizarse el estudio de utilización de los medicamentos Lopinavir-Ritonavir, se pudo concluir que la mayor tasa de uso de la DDD se presenta en el grupo etario de 35 a 54 años, evidenciándose una pertinencia en la farmacoterapia para el tratamiento del VIH-1 desde el punto de vista de rangos de dosificación y esquemas de tratamiento, observando el completo y acertado uso de las guías de manejo para los pacientes y está siendo prescrito correctamente, logrando así, un uso racional de estos medicamentos. Dado que a esa edad se tiene una mejor progresión del tratamiento se asumen los costos de la terapia, ya que también en ese rango de edad los pacientes tienen una mejor adherencia al tratamiento con una mayor asistencia de pacientes en el departamento de Bogotá para el año 2013PregradoQuímico(a) Farmacéutic

    A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
