ICF syndrome is a rare autosomal recessive immunoglobulin deficiency, sometimes combined with defective cellular immunity. Other features that are frequently observed in ICF syndrome patients include facial dysmorphism, developmental delay, and recurrent infections. The most diagnostic feature of ICF syndrome is the branching of chromosomes 1, 9, and 16 due… (More)
We describe seven Dutch patients from six families with a slowly progressive, mainly spinal cord syndrome that remained for many years the sole expression of cerebrotendinous xanthomatosis (CTX). MRI demonstrated white matter abnormalities in the lateral and dorsal columns of the spinal cord. Post-mortem examination of one of the patients showed extensive… (More)
We report a branch site mutation in the gene of the enzyme tyrosine hydroxylase (TH): a -24t > a substitution two bases upstream of the adenosine in the branchpoint sequence (BPS) of intron 11. As normal lariat formation is therefore prevented, alternative splicing takes place; use of the BPS of intron 12 results in skipping of exon 12, whereas the use of a… (More)
In situ forming bone substitute materials are attractive candidates for filling irregularly shaped defects. In this study, a chemically modified form of the Pluronic F127 hydrogel was used. Similar to the parent form, this derivative underwent a sol-gel transition in the body and additional radical curing resulted in a stable three-dimensional network gel… (More)
We report a new mutation in the sterol 27-hydroxylase (CYP 27) gene in a Dutch family with cerebrotendinous xanthomatosis: a G→A transition in the splice donor site in intron 4. This mutation leads to skipping of exon 4, resulting in a loss of 66 amino acids in the CYP 27 enzyme molecule.
Sequencing of the arylsulfatase A gene in a late infantile metachromatic leukodystrophy patient showed the presence of a 12-bp deletion in exon 2. This deletion was found in a compound heterozygous state with the previously described 287 C→T transition.
This report concerns two new mutations in the sterol 27-hydroxylase gene in two patients with cerebrotendinous xanthomatosis (CTX). In a Surinam-Creole patient (patient A), a G deletion on position cDNA 546/547 in exon 3 led to a frameshift and the introduction of a premature termination codon. In a Dutch patient (patient B), a C→T transition at position… (More)
The influence of the poly(D,L-lactic acid) (PDLLA) coating thickness on the in vitro vancomycin release from a hydroxyapatite (HA) carrier was studied. Microporous HA fibers with a porosity of 51 v% and an average pore diameter of 1.0 μm were fabricated by a diffusion-induced phase separation technique. They were loaded with 38 mg vancomycin hydrochloride… (More)
The present study evaluated an innovative technique for the manufacturing of low-dosed tablets. Tablets containing hydroxyapatite and a pore forming agent (50% (w/w) Avicel PH 200/20, 37.5% and 50% corn starch/37.5% sorbitol) were manufactured by direct compression followed by sintering. The influence of pore forming agent (type and concentration), sinter… (More)
We have standardized a long bone defect model in rabbits to quantitatively compare the bone healing performance of engineered biological implants and have tested the bone healing efficiency of porous cylindrical scaffolds (ø-h, 6-20 mm [diameter 6 mm, height 20 mm] porosity, 70%) that were produced from hydroxyapatite (HA), titanium (Ti), and a novel… (More)
