When culturing the cellulolytic-active Basidiomycete and brown-rot fungus Lenzites trabea A-419 in submerged culture with glucose and cellulose as a carbon source, the fungus only excreted β-glucosidase (EC 3.2.1.21) and an endo-1,4-β-glucanase (EC 3.2.1.4). No evidence for C1 activity (EC 3.2.1.91) was found in the culture filtrate or in the ultra(More)
An extracellular endo-1,4-β-glucanase (EC 3.2.1.4) has been isolated and purified from the culture solution of the basidiomyceteLenzites trabea grown on glucose and cellulose. Besidesβ-glucosidase activity (EC 3.2.1.21) no evidence for C1-activity (EC 3.2.1.91) in the culture solution was found. The endoglucanase has been purified in a four-step procedure(More)

BACKGROUND AND PURPOSE Previous studies of diffusion-weighted imaging (DWI) in fetuses are limited. Because of the need for normative data for comparison with young fetuses and preterm neonates with suspected brain abnormalities, we studied apparent diffusion coefficient (ADC) values in a population of singleton, nonsedated, healthy fetuses. MATERIALS AND(More)
BACKGROUND Antidepressant-induced mania (AIM) has been described in bipolar disorder (BD) and has been associated with the short-allele of the serotonin transporter gene (5-HTT). We wished to investigate the frequency of and risk factors for AIM in pediatric patients with or at high risk for BD. METHODS Fifty-two children and adolescents (30 with BD and(More)
The endogenous opioid system has been implicated in the mediation of food intake elicited by such regulatory challenges as glucoprivation induced by 2-deoxy-D-glucose (2DG) or food deprivation in rodents. Administration of the free fatty acid oxidation inhibitor, mercaptoacetate (MA), produces a potent short-term increase in feeding in rats, the mechanisms(More)
PURPOSE To develop a (1)H magnetic resonance spectroscopic imaging (MRSI) sequence that can be used to image infants/children at 3T and by combining it with diffusion tensor imaging (DTI) tractography, extract relevant metabolic information corresponding to the corticospinal tract (CST). MATERIALS AND METHODS A fast 3D MRSI sequence was developed for(More)
Adenylosuccinate lyase (ADSL) deficiency is a rare autosomal recessive neurometabolic disorder that presents with a broad-spectrum of neurological and physiological symptoms. The ADSL gene produces an enzyme with binary molecular roles in de novo purine synthesis and purine nucleotide recycling. The biochemical phenotype of ADSL deficiency, accumulation of(More)
BACKGROUND Abnormal white matter development in patients with tuberous sclerosis complex, a multisystem hamartomatous disorder caused by aberrant neural proliferation and axonal maturation, may be associated with poorer neurocognitive outcomes. The purpose of this study is to identify predictors of longitudinal changes in diffusion properties of white(More)
Voltage-gated sodium channels (Nav) are critical regulators of neuronal excitability. Genes for the α-subunits of three sodium channel subtypes-SCN1A, SCN2A, and SCN3A-are all located on chromosome 2q24. A full-term boy with an unremarkable birth history presented at 1 month of age with unusual movements that had started on day of life 2. Exam was notable(More)
