RESUMEN

El plan de estudio, documento fundamental que establece la dirección general y el contenido principal de la preparación de los profesionales, se ha ido perfeccionamiento continuamente, en correspondencia con el desarrollo cientificotécnico alcanzado. El programa de la asignatura es el que refleja las características más importantes de esta, tiene validez científica y pedagógica y contribuye a la formación del médico general, según las demandas de la sociedad cubana actual. Teniendo en cuenta las consideraciones anteriores se realizó el presente estudio con el objetivo de analizar los elementos teóricos y metodológicos del programa de la asignatura Farmacología General en el plan de estudio D para la carrera de medicina.

The syllabus, fundamental document that establishes the general direction and the main content of the professionals training, has been continually improving, in correspondence with the scientific technical development achieved. The subject program is the one that reflects its most important characteristics; it has scientific and pedagogic validity and contributes to the general doctor training, according to the demands of the present Cuban society. Taking into account the previous considerations this study was carried out aimed at analyzing the theoretical and methodological elements of the General Pharmacology subject program in the syllabus D for the medicine career.

RESUMEN

One of the cornerstones of rational drug development is the measurement of molecular parameters derived from ligand-receptor interaction, which guides therapeutic windows definition. Over the last decades, radioligand binding has provided valuable contributions in this field as key method for such purposes. However, its limitations spurred the development of more exquisite techniques for determining such parameters. For instance, safety risks related to radioactivity waste, expensive and controlled disposal of radioisotopes, radiotracer separation-dependence for affinity analysis, and one-site mathematical models-based fitting of data make radioligand binding a suboptimal approach in providing measures of actual affinity conformations from ligands and G proteincoupled receptors (GPCR). Current advances on high-throughput screening (HTS) assays have markedly extended the options of sparing sensitive ways for monitoring ligand affinity. The advent of the novel bioluminescent donor NanoLuc luciferase (Nluc), engineered from Oplophorus gracilirostris luciferase, allowed fitting bioluminescence resonance energy transfer (BRET) for monitoring ligand binding. Such novel approach named Nluc-based BRET (NanoBRET) binding assay consists of a real-time homogeneous proximity assay that overcomes radioligand binding limitations but ensures the quality in affinity measurements. Here, we cover the main advantages of NanoBRET protocol and the undesirable drawbacks of radioligand binding as molecular methods that span pharmacological toolbox applied to Drug Discovery. Also, we provide a novel perspective for the application of NanoBRET technology in affinity assays for multiple-state binding mechanisms involving oligomerization and/or functional biased selectivity. This new angle was proposed based on specific biophysical criteria required for the real-time homogeneity assigned to the proximity NanoBRET protocol.

RESUMEN

During evolution, nature has embraced different strategies for species to survive. One strategy, applied by predators as diverse as snakes, scorpions, sea anemones and cone snails, is using venom to immobilize or kill a prey. This venom offers a unique and extensive source of chemical diversity as it is driven by the evolutionary pressure to improve prey capture and/or to protect their species. Cone snail venom is an example of the remarkable diversity in pharmacologically active small peptides that venoms can consist of. These venom peptides, called conopeptides, are classified into two main groups based on the number of cysteine residues, namely disulfide-rich and disulfide-poor conopeptides. Since disulfide-poor conotoxins are minor components of this venom cocktail, the number of identified peptides and the characterization of these peptides is far outclassed by its cysteine-rich equivalents. This review provides an overview of 12 families of disulfide-poor peptides identified to date as well as the state of affairs.(AU)

RESUMEN

Specimens of the pufferfish Arothron hispidus collected at Parangipettai, on the southeast coast of India, were subjected to bacterial isolation and identification. Three species were identified, namely Bacillus sp., Kytococcus sedentarius and Cellulomonas fimi. Partially-purified microbial filtrates exhibited hemolytic activity on chicken and human erythrocytes of O, B and AB blood groups, with maximum activity of 32 HU. The microbial filtrates also presented ATPase, Mg2+-ATPase, Na+K+-ATPase and AchE enzymatic activities of positive neuromodulation in Kytococcus sedentarius with 1300, 300.1, 1549.98 and 140.55%, in Cellulomonas fimi with 620, 300, 10 and 128.42%, and in Bacillus species with 40, 200, 849.98 and 158.69%, respectively. Toxicity symptoms were observed when the bacterial filtrate was intraperitoneally injected into mice. The bacterial filtrate caused adverse effects on viability of the mouse muscle cell line (L929) and leukemia cell line (P388). Maximum level of inhibition was observed on the growth of L929 cell line. Bacillus lentimorbus inhibited the cell line from 84.03 to 94.43% whereas Bacillus species inhibited the growth in a range between 77.25 and 86.16% at the lowest dilution.(AU)

RESUMEN

La Farmacología Sanitaria se refiere a la aplicación de los conocimientos farmacológicos para el estudio y la solución de problemas sanitarios. Nació a raíz de la aparición de dos fenómenos médicos-farmacéuticos característicos de nuestra época, a saber: el profundo cambio tecnológico que mostró la elaboración de los medicamentos y el daño que éstos podían ocasionar a las grandes masas poblacionales a las cuales eran aplicados. Su impacto en nuestro país es revisado en este artículo

RESUMEN

Mientras que la mayoría de los laboratorios clínicos, tanto privados como hospitalarios, pueden proporcionarle al médico resultados sobre las concentraciones de fármacos en plasma o suero de una amplia variedad de medicamentos, muy pocos proveen la asistencia farmacológica para la correcta interpretación de los resultados, así como el apoyo para individualizar el régimen de tratamiento a partir del conocimiento farmacocinético y farmacodinámico, ya que la mayoría de ellos carece del personal entrenado en estas disciplinas de la farmacología clínic, lo que dificulta oprimir el manejo terapéutico de los pacientes. En virtud de los grandes avances en el conocimiento y las nuevas tecnologías que permiten mejorar la eficacia y seguridad de los medicamentos, se propone la creación de una unidad o departamento de farmacología clínica en el INP, que cumpla con los objetivos señalados
