Orientación metodológica para el proceso de promoción a profesor auxiliar / A methodological approach to the process of promotion to Lecturer in Medical Teaching

Se realiza un trabajo de carácter pedagógico, partiendo de la necesidad que presenta un grupo de profesores candidatos al ejercicio de oposición de la Categoría Docente de Profesor Auxiliar de la Facultad de Ciencias Medicas «Dr. Ernesto Che Guevara de la Serna"; con el propósito de contribuir al perfeccionamiento de los conocimientos y habilidades pedagógicas, mediante la orientación metodológica para el desarrollo de cada uno de los tres ejercicios que deben realizar a través de un taller, con la participación de tres profesores de elevado nivel científico técnico pedagógico propiciando el intercambio fluido y el clima favorable con el auditorio. Palabras clave: ENSEÑANZA/métodos, EVALUACIÓN EDUCACIONAL/métodos, ESCUELAS MÉDICAS, EDUCACIÓN MÉDICA. ABSTRACT A research having pedagogical characteristics starting from the need that a group of professors who opt for competitive examinations to obtain the teaching category of Lecturer in Medical Teaching at "Ernesto Guevara de la Serna" Medical School was conducted. The aim was to contribute towards the training of knowledge and pedagogical skills, through the methodological approach for the development of each of the three exercises to be perforemed by means of a workshop and with the participation of three professors having a high scientific-technical and pedagogical level which made possible a fluent interchange and a favorable atmosphere with the audience.

Estructura, logros y desafíos del Grupo de Estudios Didácticos de la Educación Superior en Salud / Structure, achievements and challenges of the Didactic Study Group in the High Education in Health

La Universidad Médica Pinareña, inmersa en dar respuesta a las demandas que el proceso formativo requiere, ha precisado lograr un clima institucional Didáctico - Pedagógico que diera respuesta a la formación de su claustro profesoral para enfrentar los retos que las condiciones actuales demandan, lo que hizo necesario proponer una estrategia de desarrollo que permitiese una estructura funcional de un Grupo de Estudios Didáctico para la Educación Médica, determinando su misión, visión y funciones. Para ello se tomaron en consideración los métodos teóricos y empíricos, que permitieron dar sustento a partir de la detección de los problemas didácticos que se presentaban en la Universidad de Ciencias Médicas Dr. Ernesto Che Guevara de la Serna de Pinar del Río. El trabajo demostró los logros alcanzados por el Grupo durante la etapa que se analiza, estableciendo los desafíos, que como retos, culminarán en paso de Grupo a Centro de Estudios Didácticos de la Educación Médica Superior para las Carreras de la Salud. Palabras Clave: educación médica/métodos, universidades.ABSTRACT Pinar del Rio Medical University is concerned about those demands that the educative process requires and it has created a didactic- pedagogical method for the professorial staff in order to face those challenges demanded by the current conditions, so it was necessary to propose an strategy being able to create a functional structure by a didactic study group in the medical education for determining its purpose, its objective and functions. With this purpose, those theoretical and empirical methods capable of allowing the detection of the didactic problems present in Pinar del Rio "Ernesto Che Guevara de la Serna" Medical School were considered. It was demonstrated the achievements obtained by this group of professors and it was established the challenges that will permit the change from a group to a centre of high medica education for health majors.

Improved purification and enzymatic properties of a mixture of Sticholysin i and II: Isotoxins with hemolytic and phospholipase A2 activities from the sea anemone Stichodactyla helianthus

Sticholysin I and Sticholysin II (StI and StII) are two potent hemolysins which form pores in natural and model membranes at nanomolar concentrations. These proteins were purified from the aqueous extract of the sea anemone Stichodactyla helianthus, Ellis 1768, by gel filtration and ionic exchange chromatography. This procedure rendered StI and StII with high purity (purification factors: 36 and 50, respectively) but a low yield of hemolytic activity, HA (95%, with an increase in specific activity: 14 times) from the animal extract using an oxidized phospholipid-based affinity chromatographic matrix binding phospholipases. Cytolysin identification in the mixture was performed by immunoblotting and N-terminal sequence analyses. Phospholipase A2 (PLA2) activity of StI–StII was relatively high (1.85 U/mg) and dependent of Ca2+. The activity resulted optimum when was measured with the mostly unsaturated soybean phosphatidylcholine (PC), when compared to the less unsaturated egg PC or completely saturated dipalmitoyl PC, in the presence of 40 mM Ca2+ at pH 8.0. This Ca2+ concentration did not exert any effect on binding of StI–StII with soybean PC monolayers. Then, PLA2 activity seems not be required to binding to membranes.The authors wish to thank INFORMATICA ddmm, Bergamo, Italy and CYTED (ENZNUT network 108RT0346), for kindly provided financial support to A. del Monte, and thanks to Havana University, Cuba, and CONACyT, México, for scientific grants.Peer Reviewe
