Antagonistic modulation of spontaneous neural network activities in isolated newborn rat brainstem preparations by opioids and methylxanthines
DownloadFall 2012
Apnea of prematurity is a common problem among the infants born before term pregnancy. Administration of respiratory stimulating drugs methylxanthines is the most frequent therapy, often in combination with the use of intubation. Opioids are used to reduce the pain associated with intubation,...

Calcium Imaging and Field Potential Analysis of Autocrine Neuromodulation in the Locus Coeruleus of Newborn Rat Brain Slices
DownloadFall 2022
The locus coeruleus (LC) is a small brainstem nucleus that controls diverse behaviours and brain functions via release of noradrenaline (NA) in the neonatal time period. There is increasing evidence of complexity in this neuron-astrocyte ‘neural’ network that remains mostly unexplored in...

Enteral diet and necrotizing enterocolitis in neonates: a scoping review and parent outcome prioritization project
DownloadFall 2017
Necrotizing enterocolitis (NEC) is a potentially life-threatening inflammatory disease of the gut affecting newborns, especially preterm infants. This complex disease is affected by numerous risk factors including genetics, intestinal microbiota, immune system responses, cardiac or respiratory...

Mechanisms of Neonatal Intestinal Failure-Associated Liver Disease: Exploring the Gut-Liver Axis
DownloadSpring 2018
Neonates with intestinal failure (IF), who must rely on parenteral nutrition (PN) for growth and maintenance of health, are at risk for intestinal failure-associated liver disease (IFALD). In neonates, short bowel syndrome (SBS) as a result of intestinal resection is the most common cause of IF....

Modulation of Spontaneous Neural Network Bursting in Newborn Rat Brain Slices by Extracellular Calcium, Methylxanthines, and Opioids
DownloadFall 2012
Spontaneous neuronal bursting appears to be pivotal for brain maturation. This thesis studied such synchronized neural network oscillations in immature newborn rat hippocampus, cortex, and locus coeruleus. For this, horizontal brain slices were generated for (simultaneous) suction electrode...

The Neonatal Locus Coeruleus is a Differentiated and Complex Neuromodulatory System as Revealed by Local Field Potential Analysis
DownloadSpring 2019
The locus coeruleus (LC) in the pons of the brainstem provides the sole source of noradrenergic afferent input to most brain structures including the cerebral cortex, hippocampus, cerebellum and spinal cord. The resulting modulation of activity is important for controlling behaviors like...
