Las redes sociales se han convertido en los últimos años, gracias al incremento en el acceso de los hogares y las personas al internet y al uso cada vez mayor de los llamados objetos inteligentes, en un extendido medio de comunicación que permite la interacción entre diversos actores y en el lugar donde se discuten múltiples temáticas, entre las que se incluye la política. A su vez, los actores políticos han visto en las redes un espacio útil para promover las narrativas y mensajes que justifiquen sus actos y decisiones, apuntalando un discurso que aprovecha el comportamiento de los usuarios al momento de diseminar información. Son estos mismos usuarios quienes propagan cualquier tipo de información, desde la más objetiva hasta aquella que ha sido distorsionada, manipulada o que es directamente falsa, aprovechándose de que las personas no quieren escuchar malas noticias y de que prefieren una mentira si esta apoya su criterio particular, además, los usuarios de las redes utilizan la posibilidad de callar voces contrarias a su creencia, añadiendo, borrando o silenciando contactos. A través de un análisis estadístico, este estudio, identifica las razones de este fenómeno y el comportamiento inherente que lo promueve en la ciudad de Quito cuando encuentra una importante porción de usuarios de redes sociales que comparten información sin verificar su procedencia ni la fiabilidad de las fuentes que la emiten, incluso si desconfían sobre la veracidad de dicha información. Social networks have become in recent years, thanks to access of households increased and people to the internet and the increasing use of so-called smart objects, in an extended media that allows interaction between different actors and in the place where multiple themes are discussed, among which politics is included. At the same time, the political actors have seen in the networks a useful space to promote the narratives and messages that justify their actions and decisions, supporting a discourse that takes advantage of the users behavior when spreading information. It is these same users who propagate any type of information, from the most objective to the one that has been distorted, manipulated or that is directly false, taking advantage of the fact that people do not want to hear bad news and that they prefer a lie if it supports their criteria. In particular, the networks users has the possibility of silencing voices contrary to their beliefs, adding, deleting or silencing contacts. Through a statistical analysis, this study identifies the reasons for this phenomenon and the inherent behavior that promotes it in the Quito city when it finds an important portion of users of social networks that share information without verifying its origin or the emision source reliability, even if they distrust the veracity of this information.

Biopsy is the microscopic analysis that verifies the presence of cancer and, in spite of being invasive and having sampling errors; it is still the standard of care nowadays. On the other hand, technology has greatly improved current medical imaging. However, an infallible imaging modality does not exist yet for the detection and diagnosis of cancer. In the last 20 years, elastography has emerged as a set of techniques which seek to detect and diagnose the cancer based on the analysis of the stiffness o f the tissue. Since cancer changes the elasticity of the tissue, elastographic techniques show qualitative and quantitative images of elasticity. Specifically for ultrasound, the most important qualitative techniques are: compression e lastography, acoustic radiation force impulse imaging and sonoelastography; while the quantitative techniques are: shear wave elasticity imaging, crawling wave sonoelastography, supersonic shear imaging and vibroelastography. The objective of this work is to present the physics phenomenon behind each technique. [ABSTRACT FROM AUTHOR]

The presence of a primary malignant tumor on each breast is called bilateral breast cancer, which can be synchronous or metachronous depending on the time to appearance of these lesions. The synchronous bilateral breast cancer refers to both primary breast tumors that are diagnosed simultaneously or in a shorter period of 3 or 6 months, while in the metachronous breast cancers, lesions appears in a period longer than 6 months. As in unilateral breast cancer, tests imaging, are the ideal methods for early detection; however, they all have variable sensitivity and specificity for the discovery of a second primary lesion. Synchronous breast cancer always presents difficulties for diagnosis; Fortunately, it is of unusual presentation with a frequency between 1 to 2.5% of all breast cancers. We report the case of a 70 years old patient, asymptomatic, which in a routine examination was diagnosed with a neoformative lesion in the right breast; However, later studies showed another suspicious lesion of malignancy in the contralateral breast. The lesions of both breasts showed similar histologic features (infiltrating ductal carcinoma) with extensive in situ carcinoma, however the results of immunohistochemistry of both breasts was different. The right breast showed negative hormone receptors,whereas the lesion of the left breast showed positive hormone receptors. [ABSTRACT FROM AUTHOR]

La aparición de cepas multirresistentes de Salmonella Typhimurium es un problema mundial, tanto en salud animal como en salud pública. El objetivo del presente trabajo fue determinar la frecuencia de algunos genes de resistencia (cmlA/ tetR, PSE-1, TEM, Sip B/C) en cepas de Salmonella spp aisladas de cerdos en rastros del Estado de México. De las 87 cepas analizadas, 22/87 (25.28%) mostraron resistencia al cloranfenicol (30 µg), 15/87 (17.24%) a la ampicilina (10 µg) y 54/87 (62.07%) fueron resistentes al sulfametoxazol (60 µg). La relación fenotípica y genotípica de las 87 cepas analizadas fue: de las 22 cepas que presentaron resistencia fenotípica al cloranfenicol, sólo 14/22 (63.63%) expresaron el gen de resistencia cmlA/tetR, y de las 65 cepas que manifestaron sensibilidad al cloranfenicol, 36/65 (55.38%) expresaron el gen de resistencia cmlA/tetR. De las 15 cepas que expresaron resistencia a la ampicilina, sólo 2/15 (13.33%) mostraron el gen PSE-1, y 7/15 (46.66%) presentaron el gen TEM, ambos genes confieren resistencia genotípica a la ampicilina. De las 72 cepas que manifestaron sensibilidad a la ampicilina, 11 (15.27%) mostraron el gen TEM, el cual da resistencia a la ampicilina. De las 87 cepas de Salmonella sólo 2/87 (2.28%) expresaron el fagotipo DT104. Las cepas que son portadoras de genes de resistencia, pero no la manifiestan fenotípicamente, no han sido expuestas a una selección por competencia, por lo tanto, no expresan la resistencia fenotípica, pero cuentan con el mecanismo necesario para expresarla.

On the basis of the story "Sin nombres, sin rostros ni rastros" by Jorge Eliécer Pardo, this paper analyzes the implications of the subject's position regarding death for the dynamics of mourning, and examines how such a position determines the subject's relation with to life. The article, which relates all of these aspects to Colombian reality, shows that a place of dignity for the living depends on the possibility of ensuring such a place for the dead.

Objective. To determine the prevalence of the consumption of alcohol and cigarette smoking and their association with cognitive impairment among older Mexican adults. Material and Methods. A total of 4 872 people over 65 years of age included in the sample of the National Mexican Health and Aging Study carried out in 2001 were questioned about their consumption of alcohol and cigarette smoking. For the classification of those subjects with cognitive impairment, the total scale of the different cognitive domains was used. The chi-square, Mann-Whitney U test, and logistical regression were used in order to find associations. Results. The prevalence of alcoholism according to CAGE was 2.8% and the prevalence of the consumption of cigarette smoking was 14%. Factors associated with the consumption of alcohol were: age 65-69 (p <0.001), men (RR 3.17, p <0.001), and high level of education (p <0.001). The association between the consumption of alcohol and cognitive impairment (χ²=6.59, p <0.01) was statistically significant. Conclusions. The prevalence of consumption of alcohol and cigarette smoking in older Mexican adults are similar to that reported in other countries; the consumption of alcohol and its association with cognitive impairment was significant.

Las especies que conforman el género Chlamydia afectan una amplia gama de hospederos animales, causando diversas patologías. Chlamydia abortus (C. abortus), Chlamydia psittaci (C. psittaci) y Chlamydia pecorum (C. pecorum) son las de mayor relevancia clínica en pequeños rumiantes a nivel mundial, ya que han sido relacionadas con problemas reproductivos, oculares y del tracto digestivo respectivamente; dos de estas (C. abortus y C. psittaci), representan un riesgo potencial zoonótico al ser humano. El diagnóstico de infecciones por organismos de este género resulta complicado; ya que, en la mayoría de los casos no hay signología clínica que indique la presencia del agente en animales afectados. Actualmente en países europeos la prevención y control principalmente de C. abortus se realiza mediante la administración de inmunógenos atenuados comerciales; sin embargo, su uso no ha mostrado resultados satisfactorios en la protección de animales susceptibles. Por lo tanto, la implementación de nuevas opciones de inmunización basadas en la utilización de proteínas recombinantes es la línea de investigación que más realce está tomando actualmente. Adicionalmente, el uso de proteínas con potencial inmunogénico podrían ser herramientas importantes para el diagnóstico, prevención y control de estos patógenos. Debido a esto, la presente revisión se centró en recapitular los estudios más actuales enfocados al uso experimental de diferentes proteínas inmunogénicas de Chlamydia spp. empleadas a nivel mundial, destacando su innovación y resultados obtenidos en los modelos experimentales.

Meat is the main vehicle for food poisoning as a result of poor hygiene in the slaughtering of animals or during the handling of carcasses. This study analyzes three municipal slaughterhouses of the Central Mexican Plateau. Two hundred and twenty eight paired samples were obtained from carcasses (n= 114) and colon content (n= 114) of cattle slaughtered at these abattoirs. Two (0.8 %) E. coli O157: NM strains from colon content and 6 (2.6 %) E. coli O157: H7 strains (5 carcasses and 1 colon content) were found. The percentage of isolation from each slaughterhouse was variable, finding significant differences (P<0.05). In E. coli O157: NM and O157: H7 strains, it was observed that the highest resistance to cephalothin was 75 %, 62.5 % carbenicillin, 50 % amikacin and 50 % gentamicin. E. coli O157: H7 strains presented 16.7 % of the eae gene, 16.7 % eae, stx1 and stx2 genes and 66.7 % eae and stx2 genes. In conclusion the results obtained show the presence of E. coli O157: H7 virulence factors and antibiotic resistance in cattle carcasses of the Central Mexican Plateau, which is considered a major source of contamination and a public health risk.

Current society requires knowledge to function properly. Scientific knowledge is generated by the scientific community, which is generally organized in research teams that develop a management to achieve its objectives. The purpose of this study is to determine the Critical Success Factors (CSFs) in the Management of Scientific Research Teams at the Universidad Centroccidental Lisandro Alvarado (UCLA), Venezuela. The methodology was based on the qualitative paradigm and the phenomenological approach for understanding the reality experienced by coordinators regarding the management of scientific research teams. We worked with a purposive sample consisting of seven (7) Coordinating Scientific Research Equipments and three (3) Research Unit Coordinators. As a technique of data collection, two (2) selfadministered structured surveys with open questions, in which coordinators expressed freely their experiences, were used. As a result the following success factors emerged in the management of scientific research teams: administrative functions, teamwork, training, resources, lines of research and dissemination. Additionally it is found that the relationship between scientific research teams and their units is characterized by a dependence-based management, information and support. The strengthening this relationship would encourage the production of knowledge in the university as a whole. [ABSTRACT FROM AUTHOR]
