“Although Parkinson’s disease (PD) has traditionally been considered to be a non-genetic disorder, recent progress in the neurogenetics of PD provided converging evidence that genetic factors play a relevant role in the etiology of PD. The strongest case for a genetic contribution TPCA-1 ic50 to PD was

made by the discovery of mutations in single genes that can cause autosomal dominant (alpha-synuclein (SNCA)) and leucine rich repeat kinase 2 (LRRK2) gene) or recessive (Parkin, PTEN-induced putative kinase 1 (PINK1), DJ-1, and ATP13A2 gene) forms of PD. Here, we review how structural and functional neuroimaging of individuals carrying a mutation in one of the PD genes has offered a unique avenue of research into the pathogenesis of PD. In symptomatic mutation carriers (i.e. those with overt disease), brain mapping can help to link the molecular pathogenesis of PD more directly with functional and structural changes in the intact human brain. In addition, neuroimaging of presymptomatic

(i.e. non-manifesting) SAHA cost mutation carriers has emerged as a valuable tool to identify mechanisms of adaptive motor reorganization at the preclinical stage that may prevent or delay clinical manifestation. In addition to mutations causing monogenic forms of PD, common polymorphisms in genes that influence mono-aminergic signaling or synaptic plasticity may have modifying effects on distinct aspects of PD. We also discuss how functional and structural neuroimaging can be used to better characterize these genotype-phenotype correlations. (C) 2009 IBRO. Published by Elsevier Ltd. All rights reserved.”
“A single-center prospective cohort study was designed to identify alterations of renal function during childhood in children born prematurely. A cohort of 143 such babies born over a 4-year period (birth weight less than 1000 g and/or less than 30 weeks of gestation) was prospectively included at birth.

Casein kinase 1 A mailing was sent to all parents to propose renal evaluation. Among the 50 included children, 23 had intrauterine and 16 had extrauterine growth retardation. When comparing both of these groups to 11 children with appropriate pre- and postnatal growth at a mean follow-up of 7.6 years, both groups of growth-restricted children had slightly but significantly lower glomerular filtration rates, measured by inulin clearance, although both groups were still within the normal range for their ages. There were no differences for other renal parameters, neonatal therapies or complications, except for postnatal corticosteroid exposure. Children with extrauterine growth restriction were found to have significantly lower protein-energy intake during their first week of life than the intrauterine growth-restricted or the normotrophic children.
