Resumen en español El magnesio es el catión extracelular más abundante en el cuerpo humano y el segundo más abundante intracelular después del potasio. Es esencial para la transferencia, almacenamiento y utilización de la energía como regulador y catalizador de más de 300 sistemas enzimáticos. La hipomagnesemia puede producir una variedad de anormalidades metabólicas y consecuencias clínicas. Puede resultar del desequilibrio entre la absorción intestinal y la excreción renal. La (mas) principal consecuencia relacionada directamente con la hipomagnesemia son las arritmias cardiovasculares por hipopotasemia secundaria, y si no se reconoce y trata puede ser fatal. En este artículo revisamos las hipomagnesemias haciendo hincapié en los mecanismos moleculares responsables de la homeostasis del magnesio, diagnóstico diferencial y tratamiento, a propósito de la descripción de las manifestaciones clínicas y bioquímicas y el defecto genético en una familia afectada de síndrome de Gitelman. Resumen en inglés Magnesium is the fourth-most abundant cation in the human body and the second-most abundant intracellular cation after potassium. Magnesium is pivotal in the transfer, storage, and utilization of energy as it regulates and catalyzes more than 300 enzyme systems. Hypomagnesemia may thus result in a variety of metabolic abnormalities and clinical consequences. It results from an imbalance between gastrointestinal absorption and renal excretion of magnesium. The main consequ (mas) ence related directly to hypomagnesemia is cardiovascular arrhythmias secondary to hipokaliemia and if this is not recognized and treated it may be fatal. In this article we review the hypomagnesemic disorders in children with emphasis on the molecular mechanisms responsible for abnormalities in magnesium homeostasis, differential diagnosis and appropriate therapy, and we describe the clinical and biochemical manifestations as well as the genetic defect in a family with Gitelman syndrome.

Domínguez, Manuel; García, Carmen
2009-01-01

Resumen en español Se analizan las posibilidades que presentan los materiales de cambio de fase en la acumulación de grandes cantidades de calor en espacios reducidos en el campo de la climatización. Se describen diversas instalaciones de climatización en donde se han incorporado de forma satisfactoria los materiales de cambio de fase (PCM), y se estudian diversos tipos de instalaciones tanto con sistemas de producción de energía térmica, como las que aprovechan el frío gratis del ai (mas) re de forma directa (free cooling) o indirecta mediante sistemas evaporativos, o los que aprovechan calores residuales o cogeneración. Considerando las múltiples posibilidades que presentan los PCM, se concluye que su empleo se generalizará en el futuro Resumen en inglés The possibilities that present phase change materials in the heat storage of big quantities of heat in reduced spaces in the field of the air conditioning are analyzed. Several installations of climatization are described where phase change materials (PCM) have been satisfactorily incorporated and diverse types of installations including systems of thermal energy production as well as those that take advantage of free cooling in direct form, or indirect form by means of e (mas) vaporative systems, or those that take advantage of residual heats or cogeneration. Considering the multiple advantages of the PCM it is concluded that they will be widely used in the future
