Several PCR assays have been developed for detecting Aspergillus fumigatus DNA in blood of patients with invasive aspergillosis. However, the best blood fraction to be assayed has not been defined and the multicopy genes used as the DNA targets for amplification not characterized. Firstly, we developed a real-time PCR assays based on the TaqMan technology(More)
OBJECTIVES The development and progression of alcoholic hepatitis are controlled by an extensive cytokine network which involves pro-inflammatory and anti-inflammatory cytokines. Genetic variations determining production of these cytokines have been described and the susceptibility to the disease may be determined by an imbalance in the expression of(More)
To improve the diagnosis of invasive aspergillosis (IA), we developed a LightCycler PCR assay targeted to Aspergillus fumigatus and A. flavus mitochondrial DNA. To avoid contamination, fully automated nucleic acid extraction with the MagNA Pure LC apparatus was used. The linearity of the results was achieved over a 6-log range of input A. fumigatus DNA,(More)
To obtain a rapid genotyping method of Candida albicans, three polymorphic microsatellite markers were investigated by multiplex PCR. The three loci, called CDC3, EF3, and HIS3, were chosen because they are on different chromosomes so as to improve the chances of finding polymorphisms. One set of primers was designed for each locus, and one primer of each(More)
The oxidation of long-chain fatty acids in mitochondria plays an important role in energy production, especially in skeletal muscle, heart and liver. Long-chain fatty acids, activated to their CoA esters in the cytosol, are shuttled across the barrier of the inner mitochondrial membrane by the carnitine cycle. This pathway includes four steps, mediated by a(More)
BACKGROUND Cystic fibrosis (CF) is caused by compound heterozygosity or homozygosity of CF transmembrane conductance regulator gene (CFTR) mutations. Phenotypic variability associated with certain mutations makes genetic counselling difficult, notably for R117H, whose disease phenotype varies from asymptomatic to classical CF. The high frequency of R117H(More)
BACKGROUND Classic galactosemia refers to galactose-1-phosphate uridyltransferase (GALT) deficiency and is characterized by long-term complications of unknown mechanism and high allelic heterogeneity of GALT gene. AIM To report molecular characterization of GALT variations in 210 French families, to analyze the structural effects of novel missense(More)
BACKGROUND AND OBJECTIVES Chronic hemolytic anemias are very frequent diseases in intertropical countries mainly caused by hemoglobin disorders. We studied a Vietnamese family in which a first child suffered from a severe transfusion-dependent anemia. The family requested an antenatal diagnosis during a second pregnancy. To characterize the molecular(More)
BACKGROUND Mutations in the cystic fibrosis (CF) transmembrane conductance regulator (CFTR) gene have been widely detected in infertile men with congenital bilateral absence of the vas deferens (CBAVD). Despite extensive analysis of the CFTR gene using varied screening methods, a number of cases remain unsolved and could be attributable to the presence of(More)
Approximately 30% of alleles causing genetic disorders generate premature termination codons (PTCs), which are usually associated with severe phenotypes. However, bypassing the deleterious stop codon can lead to a mild disease outcome. Splicing at NAGNAG tandem splice sites has been reported to result in insertion or deletion (indel) of three nucleotides.(More)
