Seizure activity has been proposed to result in the generation of reactive oxygen species (ROS), which then contribute to seizure-induced neuronal damage and eventually cell death. Although the mechanisms of seizure-induced ROS generation are unclear, mitochondria and cellular calcium overload have been proposed to have a crucial role. We aim to determine the sources of seizure-induced ROS and ...
The localization of V", gene regions to chromosome 2, on which the K locus is located, and to other chromosomes is described. The V", genes that have been transposed to other chromosomes are called orphons. The finding of two new V", genes on chromosome 22 is reported. A V", 11 gene of this region and two V", I genes of the Chr 1 and the cos 118 regions were sequenced. The two V", I orphon sequ...
A child with unilateral radial aplasia, asymmetry, other malformations, and severe physical and mental retardation is reported. In blood and bone marrow cultures a low mosaicism for trisomy 22 was found. In a few cells a chromosome 22 was missing. The importance of early cytogenetic analysis on large numbers of cells is emphasised, especially in cases of asymmetry where mosaicism is suspected.
Complete trisomy 22, with or without mosaicism, has been reported as a distinct syndrome. In this report an infant is described who was externally male but with female rudimentary internal organs and whose karyotype was 47,XX+22.
Dataflow graphs that are strongly consistent and have finite complete cycles can always be scheduled statically and executed in bounded memory. Some strongly consistent graphs without finite complete cycles can also be executed in bounded memory. We have described a clustering technique that can identify such graphs and construct their schedules. However, some perfectly correct graphs may not f...

The synthesis and resolution of a class of chiral organic fluorophores, axially chiral 4,4-difluoro-4-bora-3a,4a-diaza-s-indacenes (Ax*-BODIPY), is described. Ax*-BODIPYs were prepared through a modular synthesis combined with a late stage Heck functionalisation. Resolution was achieved by preparative chiral HPLC. Absolute stereochemical assignment was performed by comparison of experimental EC...
