It is important to investigate the effect of anesthesia on blood oxygenation level-dependent (BOLD) signals in an animal model. Many researchers have investigated the BOLD response to visual, sensory, and chemical stimuli in anesthetized rats. There are no reports, however, comparing the differences in the BOLD signal change between anesthetized and(More)
The parental origin of the X chromosome of 45,X females has been the subject of many studies, and most of them have shown that the majority (60-80%) of the X chromosomes are maternal in origin. However, studies on the parental origin of normal X chromosomes are relatively limited for Turner syndrome (TS) females with sex chromosome aberrations. In this(More)
Hyperinsulinism-hyperammonemia syndrome (HHS) is a recently identified genetic disorder characterized by hyperinsulinemic hypoglycemia with concomitant hyperammonemia. In patients with HHS, activating mutations in the glutamate dehydrogenase (GDH) gene have been identified. GDH is a key enzyme linking glutamate metabolism with the Krebs cycle and catalyzes(More)
Ornithine transcarbamylase (OTC) deficiency is the most common urea cycle disorder. It is X-linked and hemizygous new-born males usually suffer fatal hyperammonemia. In contrast, carrier females manifest variable phenotypes, ranging from asymptomatic carriers to those with severe hyperammonemia. In order to understand the correlation between X-inactivation(More)
Deficiency of mitochondrial 3-hydroxy-3-methylglutaryl CoA lyase (HL, EC4.1.3.4.) is an autosomal recessive genetic disorder characterized by acute episodes of vomiting, hypotonia, and lethargy in the neonatal period or in infancy. Except in Saudi Arabia, where HL deficiency is the most common organic acidemia, the disorder is quite rare with only 41 cases(More)
CONTEXT Mutations of multiple transcription factor genes involved in pituitary development have been identified in a minor portion of patients with combined pituitary hormone deficiency (CPHD). However, copy number aberrations involving such genes have been poorly investigated in patients with CPHD. OBJECTIVE We aimed to report the results of mutation and(More)
We report a child with neonatal-onset propionic acidemia treated with living-related liver transplantation. Despite minimal improvement in the levels of circulating propionyl CoA metabolites, hyperammonemia was corrected, and no episode of metabolic decompensation was experienced after the transplantation was performed. Natural protein intake could be(More)
CONTEXT Cytochrome P450 oxidoreductase (POR) deficiency is a rare autosomal recessive disorder characterized by skeletal dysplasia, adrenal dysfunction, disorders of sex development (DSD), and maternal virilization during pregnancy. Although multiple studies have been performed for this condition, several matters remain to be clarified, including the(More)
