Nutrients: The environmental regulation of cardiovascular gene expression
Full text linkThe complexity of nutrient-gene interactions has led to the development of a new branch in the nutrition sciences, the nutrigenomics. The individual susceptibility to nutrients based on environment → genotype → phenotype interplay makes this new research field extremely promising although complex. In this review, we highlight and examine recent findings and the most relevant hypotheses on the role of the diet in the onset and progression of cardiovascular diseases. The effect of unbalanced diets on the cardiovascular system is considered one of the most important risk factors both for ischemic and degenerative myocardial pathologies. The concept that nutrigenomics could help in improving public and personal health is becoming tangible indicating future directions for basic and applied research in the pathophysiology of cardiovascular disease. © Springer-Verlag 2007

Linear Non Linear Digital control for DC/DC Converters with fast transient response PARTE I
No full textThis article presents a digital control that improves the stability of the system, solves the problem of the limit cycle, shortens the recovery time and limits the overcoming of the rectified output voltage. Describes the linear digital nonlinear control function for DC / DC converters.
The simulation model in the mixed environment of matlab-simulink / active -hdl is described.
Preliminary results of the preliminary hardware test on a step-down-phase converter are presented and simulation and experimental results are also presented
