The role of dopamine neurotransmitter in attention deficit hyperactivity disorder (ADHD) remains controversial. Many molecular studies focusing on dopamine receptors have attempted to analyze the gene polymorphisms involved in dopaminergic transmission. Of these, rs1800497 (TaqIA) single nucleotide polymorphism (SNP) of the dopamine D2 receptor (DRD2) gene(More)
Surfactant protein C (SP-C) deficiency is a risk factor for hyperoxia-induced bronchopulmonary dysplasia in newborn infants. However, the role of SP-C deficiency in the process is unclear. Here, using neonatal rat BPD model and MLE-12, mouse alveolar epithelial type II cell, we examined the changes of SP-C levels during hyperoxia. Immunohistochemistry,(More)
OBJECTIVE Hypoxic-ischemic encephalopathy (HIE) is an important cause of morbidity and mortality in the neonates. Early and accurate diagnosis is helpful not only for assessing prognosis but also for making treatment decisions. The aim of this study was to explore the value of early assessment of HIE by applying the diffusion-weighted imaging (DWI) in acute(More)
OBJECTIVE To study the relationship between clinical and imaging features in neonates with hypoglycemic brain injury. METHODS Sixteen neonates with hypoglycemic brain injury received a MRI scan with the sequences of T1WI, T2WI and DWI within 48 hrs after admission. Of the 16 patients, 11 received second MRI scan at two weeks of their lives, and 3 received(More)
OBJECTIVE Periventricular leukomalacia (PVL), the principal form of brain injury in the premature infant, is characterized by overt focal necrotic lesions in periventricular white matter and diffuse cerebral white matter injury. The early detection of the disease is not consistently possible with cranial ultrasonography or conventional magnetic resonance(More)
Vitamin D and its receptor have a protective effect on epithelial barriers in various tissues. Low levels of vitamin D are associated with numerous pulmonary diseases, including acute lung injury (ALI) and acute respiratory distress syndrome. The present study investigated whether the vitamin D/vitamin D receptor (VDR) pathway may ameliorate(More)
OBJECTIVE To elucidate that diffusion weighted imaging (DWI) can be used to predict the injured regions of neonatal brain with hypoxic-ischemic encephalopathy (HIE) in the early phase of injury, and to measure the apparent diffusion coefficient (ADC) values in the multiple regions of the brain. METHOD The participants in this study were twenty-six infants(More)
OBJECTIVE The involvement of globus pallidus has been found in neonates with acute bilirubin encephalopathy (ABE), but so far the relationship between the severity of hyperbilirubinemia and changes of globus pallidus has not been studied further. The present study was conducted to understand possible relationship between the MRI signal changes of globus(More)
OBJECTIVE Severe and persistent hypoglycemia often leads to brain damage in neonatal period although precise definition of hypoglycemia remains controversial. Little is known whether hypoglycemic brain damage happens to the neonates with hypoglycemic symptoms in early neonatal period and no criteria to diagnose the hypoglycemic brain damage are available.(More)
The aim of the present study was to investigate water transport dysfunction in alveolar epithelial type II cells (AECII), which were exposed to hyperoxia, and to investigate the mechanism of pulmonary edema resulting from hyperoxic lung injury. The lung cells of newborn rats were isolated for primary cell culture and divided into control and experimental(More)
