Lipid peroxidation in Down syndrome caused by regular trisomy 21, trisomy 21 by Robertsonian translocation and mosaic trisomy 21.
BACKGROUND It has been suggested that an increase in oxidative stress in individuals with Down syndrome (DS) may cause adverse effects in the cell membranes through the oxidation of polyunsatured fatty acids. METHODS We examined erythrocyte malondialdehyde (MDA) levels in 100 individuals of both sexes (34 males and 66 females) with DS, aged from newborn to 29 years. The cytogenetic analysis r...
متن کاملMathematical modeling of polyamine metabolism in mammals.
Polyamines are considered as essential compounds in living cells, since they are involved in cell proliferation, transcription, and translation processes. Furthermore, polyamine homeostasis is necessary to cell survival, and its deregulation is involved in relevant processes, such as cancer and neurodegenerative disorders. Great efforts have been made to elucidate the nature of polyamine homeos...
متن کاملDislocation of the hip in trisomy 21.
Almost one child in twenty with trisomy 21 will develop spontaneous dislocation of the hip between learning to walk and the age of 10 years. After the age of two years spontaneous habitual dislocation may occur. If left untreated, acute dislocation, subluxation and fixed dislocation follow in sequence. The natural history of the condition is described and the clinical and radiological features ...
متن کاملTrisomy of chromosome 21 in leukemogenesis.
Extra copies of chromosome 21 are often found in sporadic leukemias. Constitutional trisomy 21 of Down syndrome (DS) is associated with markedly increased risk for childhood leukemia. Thus the oncogenic role of trisomy 21 in the more common sporadic childhood leukemias may be revealed through the investigations of the relatively rare leukemias of DS. Recent studies of the megakaryoblastic leuke...
متن کاملTrisomy 21 mosaicism in a woman with two children with trisomy 21 Down's syndrome.
Trisomy 21 mosaicism in a woman with two children with trisomy 21 Down's syndrome* Summary. Trisomy 21 mosaicism was identified by fluorescent quinacrine banding in a phenotypically normal mother, who gave birth to two children with trisomy 21 Down's syndrome. Trisomy 21 Down's syndrome associated with maternal mosaicism was first described by Smith et al in 1962. Since then there have been at ...
