This is a review of the articles dealing with basic science published in recent issues of Archivos de Bronconeumología. Of particular interest with regard to chronic obstructive pulmonary disease were an article on extrapulmonary inflammation and oxidative stress and another on bronchial remodeling. The articles relating to asthma included a review on the use of drugs that block free immunoglobulin-E and an article about the contribution of experimental models to our knowledge of this disease. Two of the most interesting articles on the topic of lung cancer dealt with gene therapy and resistance to chemotherapy. Also notable were 2 studies that investigated ischemia-reperfusion injury. One evaluated tissue resistance to injury while the other analyzed the role played by interleukin-8 in this process. On the topic of pulmonary fibrosis, an article focused on potential biomarkers of progression and prognosis; others dealt with the contribution of experimental models to our understanding of this disorder and the fibrogenic role of transforming growth factor [.beta]. In the context of both sleep apnea syndrome and pulmonary infection, studies investigating the role of oxidative stress were published. Finally, 2 studies analyzed the diagnosis and treatment of tuberculosis and other pulmonary infections.

Se han revisado los artículos relacionados con las ciencias básicas que se han publicado recientemente en ARCHIVOS DE BRONCONEUMOLOGÍA. Respecto de la enfermedad pulmonar obstructiva crónica, destacan los relacionados con el estrés oxidativo y la inflamación extrapulmonar, y un estudio sobre la remodelación bronquial. Los artículos acerca del asma se centraron en revisiones sobre el uso de fármacos que bloquean la inmunoglobulina E libre y sobre las aportaciones de los modelos experimentales de la enfermedad. Respecto del cáncer de pulmón, cabe mencionar 2 trabajos centrados en la genoterapia y las resistencias ante la quimioterapia. También destacan 2 estudios sobre la lesión por isquemia-reperfusión, que valoraron el tiempo de resistencia tisular ante esta noxa y el papel de la interleucina-8. En el campo de la fibrosis pulmonar se revisaron los potenciales biomarcadores de progresión y pronóstico, así como el papel de los modelos experimentales de la enfermedad, publicándose además un trabajo sobre el papel fibrogénico del factor transformador de crecimiento beta. Sobre el síndrome de apneas del sueño y las infecciones pulmonares se publicaron sendos estudios acerca del papel del estrés oxidativo. Finalmente, 2 trabajos de investigación analizaron el diagnóstico y tratamiento de la tuberculosis y otras infecciones pulmonares.
