The effects of acute or repeated administrations of the selective kappa opioid receptor agonists U-69593 and U-50488H on cocaine-induced locomotor stimulation were examined in the rat. Acute administration of cocaine (10-30 mg/kg i.p.) produced a dose-dependent increase in locomotor activity. A single injection of U-69593 (0.04-0.32 mg/kg s.c.) or U-50488H(More)
N-linked glycosylation is the most frequent modification of secreted and membrane-bound proteins in eukaryotic cells, disruption of which is the basis of the congenital disorders of glycosylation (CDGs). We describe a new type of CDG caused by mutations in the steroid 5alpha-reductase type 3 (SRD5A3) gene. Patients have mental retardation and ophthalmologic(More)
Cerebellar hypoplasia and slowly progressive ophthalmological symptoms are common features in patients with congenital disorders of glycosylation type I. In a group of patients with congenital disorders of glycosylation type I with unknown aetiology, we have previously described a distinct phenotype with severe, early visual impairment and variable eye(More)
Chorea-acanthocytosis (ChAc) is a rare autosomal recessive neurodegenerative disorder caused by loss of function mutations in the vacuolar protein sorting 13 homolog A (VPS13A) gene that encodes chorein. It is characterized by adult-onset chorea, peripheral acanthocytes, and neuropsychiatric symptoms. In the present study, we performed a comprehensive(More)
OBJECTIVE To longitudinally analyze changes in plexiform neurofibroma (PN) volume in relation to age and body growth in children and young adults with neurofibromatosis type 1 and inoperable, symptomatic, or progressive PNs, using a sensitive, automated method of volumetric MRI analysis. METHODS We included patients 25 years of age and younger with PNs(More)
The non-selective opioid antagonist naltrexone and the partial agonist buprenorphine have been reported to reduce cocaine self-administration (SA) and relapse in both humans and rhesus monkeys. Data suggesting an involvement of delta-opioid receptors in modulating the conditioned rewarding effects of cocaine were also recently presented. In view of such(More)
Hearing loss is the most common birth defect and the most prevalent sensorineural disorder in developed countries. More than 50% of prelingual deafness is genetic, most often autosomal recessive and nonsyndromic, of which 50% can be attributed to the disorder DFNB1, caused by mutations in GJB2 and GJB6. Sensorineural hearing loss and male infertility(More)
We aimed to define the dose of pirfenidone in children and adolescents with neurofibromatosis 1 and plexiform neurofibromas that is pharmacokinetically comparable to the active adult dose. Pirfenidone was administered orally on a continuous dosing schedule. The starting dose level was 250 mg/m2/dose. The second dose level (500 mg/m2/dose) corresponded to(More)
The 2011 annual meeting of the Children's Tumor Foundation, the annual gathering of the neurofibromatosis (NF) research and clinical communities, was attended by 330 participants who discussed integration of new signaling pathways into NF research, the appreciation for NF mutations in sporadic cancers, and an expanding pre-clinical and clinical agenda. NF1,(More)
Neurofibromatosis Type 2 (NF2) is a rare autosomal dominant disorder characterized by the development of benign tumors of the peripheral nervous system and the CNS, including schwannomas, meningiomas, and ependymomas. The gene responsible for the development of NF2 acts as a tumor suppressor gene. Stereotactic radiotherapy (SRT) or single-fraction(More)
