Metabolic Syndromes in Colombia
(The Kitakanto Medical Journal, 2005)Metabolic Syndromes and their consequences are common causes of morbi-mortality in Colombia. Although much of the scarce funding research in Latin America are often focused to support studies on infection diseases, the ... -
Stability analysis of the supply chain by using neural networks and genetic algorithms
(IEEE Xplore, 2008-01-04)Effectively managing a supply chain requires visibility to detect unexpected variations in the dynamics of the supply chain environment at an early stage. This paper proposes a methodology that captures the dynamics of the ... -
New polymorphism in the NCF¿2 gene leading to alternative splicing without altering gene expression or the respiratory burst activity
(Am J Hematol, 2008-02)The p67-phox protein is an essential component for activating the NADPH oxidase of phagocytes. Mutations affecting this gene lead to an autosomal recessive form of chronic granulomatous disease (CGD), a primary immunodeficiency ... -
