Abstract:
Salamanders found at different localities nearby Mérida city, Venezuela, are thus far reported as Bolitoglossa orestes or B.spongai. However, morphological ambiguities among individuals from several populations of both putative species, besidestheir reported disparate geographical distributions, prompted us to clarify the specific identity of these bolitoglossines throughthe sequence analysis of their corresponding 16S rRNA genes. Seventeen specimens belonging to the vertebrates collection ofUniversidad de Los Andes (CVULA), collected at separated cloud forests in Sierra La Culata (San Eusebio, Macho Capaz andSan Javier del Valle) and Sierra Nevada de Mérida (La Mucuy), were used to extract DNA upon tissue digestion. Sequenceanalysis of the 16S rRNA gene supports a biogeographical scenario where, so far, there is only one salamander species for eachsierra: B. orestes, which is widely distributed in Sierra La Culata, and a so far undescribed species of a Venezuelan bolitogloss-ine apparently restricted to Sierra Nevada de Mérida. Based on our molecular results and an examination of morphological evidence, B. spongai should be considered a synonym of B. orestes.

Abstract:
Introducción: Esta investigación ajusta un modelo para la prevalencia del Síndrome Metabólico y, evalúa el nivel de acuerdo en la clasificación de la población general, área metropolitana, municipio Libertador de la ciudad de Mérida, Venezuela, 2005, según las variables PREV1 y PREV2, diseñadas empleando criterios de NCPE-ATP III. Materiales y Métodos: Se propone el uso del coeficiente kappa de Cohen para medir dicho acuerdo. Se emplea el procedimiento propuesto por Nava y Sinha (2007), para ajustar un modelo de regresión logística que relaciona la prevalencia de Síndrome Metabólico (SM), también conocido como Síndrome X, con las variables sexo, talla, peso, índice de masa corporal (IMC), alcohol, tabaco, sedentarismo, glucosa, HDL, triglicéridos, obesidad, clase social, edad y estado civil; considerando información referente a un grupo de 275 habitantes. Resultados discusión: Los resultados indican que las variables relacionadas en forma significativa con la presencia de SM son sexo, IMC, glucosa, HDL, triglicéridos y edad. Glucosa, HDL, triglicéridos e índice de masa corporal corregido, son variables que incrementan en forma significativa las posibilidades de prevalencia de SM. Conclusiones: Se concluye, que las mujeres tienen mayores posibilidades que los hombres de presentar SM; el valor obtenido para el coeficiente kappa de Cohen, indica que existe un alto acuerdo en la clasificación de los individuos considerados en la investigación según las variables PREV1 y PREV2, es decir, cualquiera de esas variables puede usarse para determinar la prevalencia de SM.Introduction: This research sets a model for the prevalence of Metabolic Syndrome and evaluates the level of agreement in the classification of the general population, metropolitan area, Libertador municipality of the city of Mérida, Venezuela, 2005, according to variables PREV1 and PREV2, designed using the criteria of theNCPEATPIII. Materials and methods: We propose the use of Cohen’s kappa coefficient to measure this deal. This paper uses the proposed procedure by Nava and Sinha (2007), to fit a logistic regression model that relates the prevalence of metabolic syndrome (MS) or syndrome X, with the variables sex, height, weight, CBMI, alcohol, snuff, sedentary lifestyle, glucose, HDL, triglycerides, obesity, social class, age and marital status, considering information on a group of 275 people. Results and discussion: Results shows that the variables significantly associated with the presence of MS are sex, CBMI, glucose, HDL, triglycerides and age. Glucose, HDL, triglycerides and CBMI, are variables that increases significantly the chances of prevalence of MS. Conclusions: We conclude that women are more likely than men to have SM; the value obtained for the Cohen kappa coefficient, indicate a high agreement on the classification of individuals considered in the investigation according to the variables PREV1 and PREV2, i.e. any of these variables can be used to determine the prevalence of MS.

Abstract:
Abstract. The first long-term measurements of aerosol number and size distributions in South-American tropical free troposphere were performed from March 2007 until Mai 2009. The measurements took place at the high altitude Atmospheric Research Station Alexander von Humboldt. The station is located on top of the Sierra Nevada mountain ridge at 4765 m a.s.l. nearby the city of Mérida, Venezuela. Aerosol size distribution and number concentration data was obtained with a custom-built Differential Mobility Particle Sizer (DMPS system) and a Condensational Particle Counter (CPC). The analysis of the annual and diurnal variability of the tropical free troposphere (FT) aerosol focused mainly on possible links to the atmospheric general circulation in the tropics. Considerable annual and diurnal cycles of the particle number concentration were observed. Highest total particle number concentrations were measured during the dry season (519±613 cm−3), lowest during the wet season (318±194 cm−3). The more humid FT contained generally higher aerosol particle number concentrations (573±768 cm−3 during dry season, 320±195 cm−3 during wet season) than the dry FT (454±332 cm−3 during dry season, 275±172 cm−3 during wet season), indicating the importance of convection for aerosol distributions in the tropical FT. The diurnal cycle in the variability of the particle number concentration was mainly driven by local orography.

Abstract:
RESUMEN. Introducción: Un resultado citológico que informa la presencia de células escamosas con atipias que no descartan una Lesión Intraepitelial Escamosa de Alto Grado (ASC-H) es clínicamente significativo, ya que aproximadamente el 50% de estas pacientes podrían presentar una lesión pre-maligna durante la evaluación de dichas atipias morfológicas. Objetivo: Describir las alteraciones cito-morfológicas más frecuentemente halladas en los extendidos citológicos de cuello uterino categorizados como ASC-H, agrupadas según resultado histopatológico de seguimiento. Metodología: Se desarrolló un estudio retrospectivo en el Laboratorio de Citología de la Facultad de Farmacia y Bioanálisis, Universidad de Los Andes y en la Clínica de Prevención del Cáncer, de la Sociedad Anticancerosa, Capitulo Mérida-Venezuela. Fueron incluidos los casos analizados entre enero-2010 y diciembre-2016 con resultados citológicos cervicales ASC-H, se reevaluaron los extendidos citológicos y se agruparon los criterios cito-morfológicos más frecuentemente hallados según biopsia benigna y anormal. Resultados: El 60,0% de las citologías cervicales categorizadas como ASC-H mostraban atipias en las células escamosas profundas frecuentemente sobre fondo inflamatorio cuando el hallazgo histopatológico era benigno, mientras que en los casos con biopsia anormal como Neoplasia Intraepitelial Cervical (CIN) 1, 2 o 3 y/o HPV se encontró que la mayoría (73,7%) de las atipias estaban presentes en células metaplásicas inmaduras, sin inflamación. Conclusiones: Los criterios cito-morfológicos que deben considerarse para designar un extendido citológico como sospechoso de neoplasia (ASC-H) son: anisocariosis, hipercromasia, cromatina y membrana nuclear irregular sobre un fondo de frotis limpio. Dichas alteraciones siempre deben correlacionarse con datos clínicos aportados, que incluye básicamente la edad
