VALIDACIóN EMPíRICA DEL MODELO DE FORMULACIóN CLíNICA POR PROCESOS BáSICOS DE CASTRO Y áNGEL

Abstract: the aim of this research was to carry out the empirical validation of the clinical formulation model founded on basic processes and proposed by castro and angel (1998). a quasi-experimental trans-sectional descriptive and comparative design with three groups was used. participants were thirty psychologists assigned to the three groups according to their academic background and clinical experience (novice, intermediate an expert). they received written information about a clinical case in order to formulate it using castro and angel's model. validity indexes were obtained by calculating the percentage of agreements between the formulations of the three groups and a reference formulation; a special instrument was designed for this purpose. the statistical tests h of kruskal-wallis and w of kendall were also used. results showed that, in general, the model oriented the development of the formulations in the majority of aspects regardless the clinician's level of experience. this points out the empirical validity of the model; nevertheless, the levels of agreement were not high and the differences lie in one of the model's basic categories. this is the first study aimed at validating castro and angel's model; its results will allow the restructuring of that model and in turn will lay the foundations for validating it in future research projects.

Abstract: the emergence of community-acquired methicillin-resistant staphylococcus aureus (ca-mrsa) as a cause of severe infections has been described in the recent years. in 2006, the first report of skin and soft tissue infection by ca-mrsa was published in colombia. herein, two additional cases of ca-mrsa are reported with a clinical course characterized by rapid progression, prolonged stay in the intensive care unit and complication of pneumonia with the onset of empyema. both adult patients developed acute renal failure, and were treated with linezolide; the subsequent clinical response showed adequate treatment response. molecular characterization of the isolates indicated the presence of the meca gene carrying the cassette sccmec type iv and the production of the toxin panton-valentine leukocidin.

Bistua : Revista de la Facultad de Ciencias Básicas , 2011,
Abstract: Los Aceites Esenciales (AEs) fueron obtenidos a partir de hojas de la especie Calycolpus moritzianus, recolectada en cinco regiones del departamento Norte de Santander: Chinacota, Ocana, Pamplonita, Salazar y Toledo, por el metodo Destilacion-Extraccion con Solvente Simultanea (DES). El analisis cualitativo de los constituyentes volatiles mayoritarios del AE, se realizo por la tecnica de Cromatografia de Gases de Alta Resolucion (CGAR), utilizando el Detector de Ionizacion de Llama (FID) y el Detector Selectivo de Masas (MSD). Se logro la identificacion de treinta y dos (32) compuestos, destacandose por su abundancia el Limoneno (17-38%), el 1,8-Cineol o Eucaliptol (12-43.3%),el a-Pineno (2.3-5.6%), el B-Cariofileno(0.1-8.9%), a-Terpineol (0.2-5.5%) y el Guaiol (0.3-20.2%), los cuales varian su concentracion relativa segun la region de procedencia. El analisis cuantitativo de los componentes volatiles mayoritarios se realizo empleando la tecnica de normalizacion, estandarizacion externa e interna y finalmente, con los datos obtenidos se efectuo el respectivo analisis estadistico de los componentes principales (PCA).

Abstract: both hepatitis b and hepatitis c viruses (hbv and hcv) infection are common in hiv-infected individuals as a result of shared risk factors for acquisition. a serological study for hbv and hcv was performed in 251 hiv-positive individuals from medellín, colombia. a qualitative rt-pcr for hcv was done in 90 patients with cd4+ t-cell count < 150 per mm3. serological markers for hbv infection were present in 97 (38.6%) patients. thirty six of them (37.1%) had isolated anti-hbc. a multivariate analysis indicated that the following risk factors were significantly associated with the presence of these markers: age (or = 1.05, 95% ci: 1.01-1.08), pediculosis pubis (or = 1.83, 95% ci: 1.01-3.33), men who have sex with men and women (or = 3.23, 95% ci: 1.46-7.13) and men who have sex only with men (or = 3.73, 95% ci: 1.58-8.78). the same analysis restricted to women showed syphilis as the only significant risk factor. thus, hbv infection was considerably associated with high risk sexual behavior. hcv was present in only two (0.8%) of hiv patients. both of them were positive by rt-pcr and anti-hcv. this low frequency of hiv/hcv coinfection was probably due to the uncommon intravenous drug abuse in this population. the frequent finding of isolated anti-hbc warrants molecular approaches to rule out the presence of cryptic hbv infection.

Abstract: In July 5th 2014 an occultation of Mars by the Moon was visible in South America. Citizen scientists and professional astronomers in Colombia, Venezuela and Chile performed a set of simple observations of the phenomenon aimed to measure the speed of light and lunar distance. This initiative is part of the so called "Aristarchus Campaign", a citizen astronomy project aimed to reproduce observations and measurements made by astronomers of the past. Participants in the campaign used simple astronomical instruments (binoculars or small telescopes) and other electronic gadgets (cell-phones and digital cameras) to measure occultation times and to take high resolution videos and pictures. In this paper we describe the results of the Aristarchus Campaign. We compiled 9 sets of observations from sites separated by distances as large as 2,500 km. We achieve at measuring the speed of light in vacuum and lunar distance with uncertainties of few percent. The goal of the Aristarchus Campaigns is not to provide improved values of well-known astronomical and physical quantities, but to demonstrate how the public could be engaged in scientific endeavors using simple instrumentation and readily available technological devices. These initiatives could benefit amateur communities in developing countries increasing their awareness towards their actual capabilities for collaboratively obtaining useful astronomical data. This kind of exercises would prepare them for facing future and more advanced observational campaigns where their role could be crucial.
Into the life and death: RecA a WISE factor working to integrate survival and evolution in Escherichia coli  [PDF]
José María Gómez Gómez
Advances in Bioscience and Biotechnology (ABB) , 2013, DOI: 10.4236/abb.2013.43A059
Abstract:

Escherichia coli RecA has been considered traditionally a cellular protein with multiple vital functions working to ensure the maintenance of integrity of genome in each individual bacterial cell as well as promoting swarming migration in collectivity. On the contrary, recently it has been described that RecA promotes cellular apoptotic-like death (ALD), a pathway of programmed cellular death (PCD). In fact, RecA has been dubbed as the major apoptotic executor in E. coli. From these studies, RecA emerges as a prototypical Gin/Gan protein that despite of their intrinsic vital and lethal anfi-funcionality becomes in a WISE factor: a Worker to Integrate Survival and Evolution in E. coli evolving populations living in community. Here, I provide a review of recent experimental and conceptual advances trying to understand these RecA’s antagonistic roles in appearance contradictory under a unified biological vision.

Equilibrium Dynamics in the Neoclassical Growth Model with Habit Formation and Elastic Labor Supply  [PDF]
Manuel A. Gómez
Theoretical Economics Letters (TEL) , 2012, DOI: 10.4236/tel.2012.25087
Abstract: This note analyzes the equilibrium dynamics in the neoclassical growth model with habit-forming preferences and elastic labor supply. Habits enter into utility in a multiplicative way. The specification of the habit formation process comprises the particular cases of internal and external habits. Existence, uniqueness and saddle-path stability of the steady state are proved analytically.
