Bile duct ligation (BDL) in developing rats causes cholestasis, impaired liver function and cognition. Because both nitric oxide (NO) and ammonia are implicated in hepatic encephalopathy (HE), we hypothesized that asymmetric dimethylarginine (ADMA), an endogenous NO synthase inhibitor, and ammonia affect cognition in young rats with BDL. Four groups of(More)
Emerging evidence indicates that early maternal care permanently modifies the activity of hypothalamic-pituitary-adrenal (HPA) axis and is a critical factor in determining the capacity of the brain to compensate for later encountered insults. The purpose of this study was to determine the role of corticosterone (CORT) in the detrimental effects of neonatal(More)
Hypoxic-ischemic (H-I) encephalopathy is a major contributor to morbidity and mortality in infants and children. To delineate the nature and mechanism(s) of neuroprotection via erythropoietin (EPO) gene therapy, we evaluated the effects of single intravenous injection of naked plasmid DNA encoding EPO in H-I infant rats. Single administration of naked(More)
The central nervous system (CNS) exhibits remarkable plasticity in early life and can be altered significantly by various prenatal influences. We previously showed that prenatal exposure to morphine altered kinetic properties of N-methyl-D-aspartate (NMDA) receptor-mediated synaptic currents in the hippocampus of young rat offspring at the age of 14 days(More)
Elevated asymmetric dimethylarginine (ADMA) levels and nitric oxide (NO) deficiency are associated with the development of hypertension. Metformin, an antidiabetic agent, is a structural analog of ADMA. We examined whether metformin can prevent the development of hypertension in spontaneously hypertensive rats (SHRs) by restoration of ADMA-NO balance. SHRs(More)
Tuberculous myositis is extremely rare, even in immunocompromised hosts. We present a case of disseminated tuberculous myositis in a girl with secondary acute myelogenous Leukemia following successful chemotherapy for undifferentiated sarcoma of the maxillary sinus. The diagnosis was established by direct visualization of acid-fast bacilli in the biopsied(More)
Melatonin (N-acetyl-5-methoxytryptamine) is an endogenously produced indoleamine secreted by the pineal gland and the secretion is suppressed by light. Melatonin is a highly effective antioxidant, free radical scavenger, and has anti-inflammatory effect. Plenty of evidence supports the utility of melatonin in adults for cancer, neurodegenerative disorders,(More)
BACKGROUND Recent studies have shown that microRNA-29 (miR-29) is significantly decreased in liver fibrosis and that its downregulation influences the activation of hepatic stellate cells (HSCs). In addition, inhibition of the activity of histone deacetylases 4 (HDAC4) has been shown to strongly reduce HSC activation in the context of liver fibrosis. (More)
OBJECTIVE Kawasaki disease (KD) is an acute febrile vasculitic syndrome in children. CD40 ligand (CD40L) has been implicated in certain types of vasculitis. We proposed that CD40L expression might be correlated with coronary artery lesions in KD. METHODS Blood samples were collected from 43 patients with KD before intravenous immunoglobulin (IVIG)(More)
Nitric oxide (NO) deficiency is associated with development of hypertension. We examined whether melatonin protects against the blood pressure increase is because of the restoration of the NO pathway. Spontaneous hypertensive rats (SHR) and control normotensive Wistar Kyoto (WKY) rats aged 4 weeks were assigned to four groups (N=6 for each group): untreated(More)
