    • Novel Modeling of Work of Breathing for Its Optimization During Increased Respiratory Efforts 

      Serna Higuita, Leidy Yanet; Mañanas Villanueva, Miguel Ángel; Hernández Valdivieso, Alher Mauricio; Marín Sánchez, Jesús; Benito Vales, Salvador (2016-09-01)
      Article
      Accés obert
      The respiratory control system is one of the most complex physiological systems, whose controller has been extensively modeled based on the criterion of minimizing work of breathing (WOB). However, cost functions and their ...

    • Optimization techniques in respiratory control system models 

      Serna Higuita, Leidy Yanet; Mañanas Villanueva, Miguel Ángel; Marín Sánchez, Jesús; Hernández Valdivieso, Alher Mauricio; Benito, S. (2016-11-01)
      Article
      Accés obert
      One of the most complex physiological systems whose modeling is still an open study is the respiratory control system where different models have been proposed based on the criterion of minimizing the work of breathing ...

    • Potential clinical application of surface electromyography as indicator of neuromuscular recovery during weaning tests after organophosphate poisoning 

      Salazar Sánchez, Maria Bernarda; Hernández Valdivieso, Alher Mauricio; Mañanas Villanueva, Miguel Ángel; Zuluaga Salazar, Andrés Felipe (2017-06)
      Article
      Accés obert
      This study aimed to explore the usefulness of measuring respiratory muscle activity in mechanically ventilated patients suffering from acute organophosphate poisoning, with a view towards providing complementary information ...

    • Precuneus failures in subjects of the PSEN1 E280A family at risk of developing Alzheimer's disease detected using quantitative electroencephalography 

      Ochoa Gómez, John Fredy; Alonso López, Joan Francesc; Duque, Jon; Tobón, Carlos; Baena, A.; Lopera, Francisco; Mañanas Villanueva, Miguel Ángel; Hernández Valdivieso, Alher Mauricio (2017-07-01)
      Article
      Accés obert
      Presenilin-1 (PSEN1) mutations are the most common cause of familial early onset Alzheimer's disease (AD). The PSEN1 E280A (E280A) mutation has an autosomal dominant inheritance and is involved in the production of amyloid-ß. ...

    • Successful object encoding induces increased directed connectivity in presymptomatic early-onset Alzheimer's disease 

      Ochoa Gómez, John Fredy; Alonso López, Joan Francesc; Duque, Jon; Tobón, Carlos; Mañanas Villanueva, Miguel Ángel; Lopera, Francisco; Hernández Valdivieso, Alher Mauricio (2017-01-01)
      Article
      Accés obert
      Background: Recent studies report increases in neural activity in brain regions critical to episodic memory at preclinical stages of Alzheimer’s disease (AD). Although electroencephalography (EEG) is widely used in AD ...

    • Virtual laboratory for simulation and learning of cardiovascular system function in BME studies 

      Hernández Valdivieso, Alher Mauricio; Salazar Sánchez, Maria Bernarda; Urrego Higuita, David Alexander; Costa Castelló, Ramon; Mañanas Villanueva, Miguel Ángel (2011-09)
      Article
      Accés obert
      The application of engineering system analysis is a very important field in biomedical engineering (BME) studies: modeling, simulation and control of the most important physiological systems. A virtual laboratory for ...
