Animated solid model of the lung constructed from unsynchronized MR sequential images
(ELSEVIER SCI LTD, 2009)
This work discusses a 4D lung reconstruction method from unsynchronized MR sequential images. The lung, differently from the heart, does not have its own muscles, turning impossible to see its real movements. The visualization ...
Registration of temporal sequences of coronal and sagittal MR images through respiratory patterns
(ELSEVIER SCI LTD, 2011)
This work discusses the determination of the breathing patterns in time sequence of images obtained from magnetic resonance (MR) and their use in the temporal registration of coronal and sagittal images. The registration ...
Maternal chronic hypoxia increases expression of genes regulating lung liquid movement and surfactant maturation in male fetuses in late gestation
Chronic fetal hypoxaemia is a common pregnancy complication that may arise from maternal, placental and/or fetal factors. Respiratory outcome of the infant at birth likely depends on the duration, timing and severity of ...
Ventilation Patterns Influence Airway Secretion Movement
(DAEDALUS ENTERPRISES INC, 2008)
BACKGROUND: Retention of airway secretions is a common and serious problem in ventilated patients. Treating or avoiding secretion retention with mucus thinning, patient-positioning, airway suctioning, or chest or airway ...
Valoración de la dorsiflexión de los basquetbolistas en la Federación Deportiva de Santa Elena utilizando los test de Lunge y Silfverskiold.
(Universidad Católica de Santiago de Guayaquil, 2021)
Molecular regulation of lung maturation in near-term fetal sheep by maternal daily vitamin C treatment in late gestation
BACKGROUND: In the fetus, the appropriate balance of prooxidants and antioxidants is essential to negate the detrimental effects of oxidative stress on lung maturation. Antioxidants improve respiratory function in postnatal ...
Critical protective role for annexin 1 gene expression in the endotoxemic murine microcirculation
The inflammatory response is a protective process of the body to counteract xenobiotic penetration and injury, although in disease this response can become deregulated. There are endogenous biochemical pathways that operate ...
