The cholinergic system in Down's syndrome
2006
The cholinergic system is one of the most important modulatory neurotransmitter systems in the brain. Alterations of the transmission communicators are accompanied by reduction of the cortical activity, which is associated with a learning and memory deficit. Down's syndrome is a pathological condition characterized by a high number of abnormalities that involve the brain.The cholinergic system is involved in alterations of the neurological system such as severe learning difficulties.To explain these alterations, important results are obtained from studies about murine trisomy 16 (animal model of Down's syndrome).The results obtained provide useful elements in the improvement of knowledge ab…

Attribution style in adolescents with Down’s sindrome
2005
Educational research places emphasis on the fact that individuals who have experienced repeated failures may develop an attribution profile characterized by a bias towards primarily external causes. The aim of this study is to compare the attribution style of adolescents with Down's syndrome with that of normal children and adolescents matched for mental and chronological age; three groups consisting of 10 participants each were employed, an experimental group and two control groups were employed. The experimental group were Down's syndrome adolescents. Participants in the first control group were matched to the experimental groups for mental age, and those in the second for chronological a…
A population-based study relevant to seasonal variations in causes of death in children undergoing surgery for congenital cardiac malformations
2007
AbstractAimsOur objectives were, first, to study seasonal distribution of perioperative deaths within 30 days after surgery, and late death, in children undergoing surgery for congenitally malformed hearts, and second, to study the causes of late death.MethodsWe analysed a retrospective cohort of 1,753 children with congenital cardiac malformations born and undergoing surgery in the period from 1990 through 2002 with a special focus on the causes of late death. The data was obtained from the registry of congenital cardiac malformations at Rikshospitalet, Oslo, and the Norwegian Medical Birth Registry. The mean follow-up from birth was 8.1 years, with a range from zero to 15.2 years.ResultsD…
SPANX-B and SPANX-C (Xq27 region) gene dosage analysis in Down’s syndrome subjects with undescended testes
2009
Down’s syndrome (DS) is one of the most common numer- ical chromosomal aberrations, usually caused by trisomy of chromosome 21, and is frequently complicated with congen- ital heart defects, duodenal obs truction and other conditions including undescended testis (UDT) (Fonkalsrud 1970). The incidence of undescended testes in DS was reported to be 6.52% (Chew and Hutson 2004) while the incidence of UDT in the first year is approximately 0.2%–0.8% in the nor- mal population (Benson et al . 1991; Ichiyanagi et al . 1998). Rapley et al . (2000) provided evidence for a testicular germ- cell tumours (TGCT) predisposition locus at Xq27; the au- thors obtained an hlod score of 4.7 from families wit…
