Mammalian cytochrome c oxidase (COX) catalyses the transfer of reducing equivalents from cytochrome c to molecular oxygen and pumps protons across the inner mitochondrial membrane. Mitochondrial DNA (mtDNA) encodes three COX subunits (I-III) and nuclear DNA (nDNA) encodes ten. In addition, ancillary proteins are required for the correct assembly and(More)
BACKGROUND Linezolid is an oxazolidinone antibiotic that is increasingly used to treat drug-resistant, gram-positive pathogens. The mechanism of action is inhibition of bacterial protein synthesis. Optic and/or peripheral neuropathy and lactic acidosis are reported side effects, but the underlying pathophysiological mechanism has not been unravelled. (More)
The purpose of this study was to test the reliability of a new handgrip exercise protocol measuring forearm oxygenation in 20 healthy subjects on two occasions. The retest took place 48 h later and at the same time of the day. The incremental exercise consisted of 2 min steps of cyclic handgrip contraction (1/2 Hz) separated by 1 min of recovery. The(More)
Leukodystrophies are a heterogeneous group of severe genetic neurodegenerative disorders. A multiple mitochondrial dysfunctions syndrome was found in an infant presenting with a progressive leukoencephalopathy. Homozygosity mapping, whole exome sequencing, and functional studies were used to define the underlying molecular defect. Respiratory chain studies(More)
Steroids and adrenocorticotrophic hormone (ACTH) have been used for the treatment of infantile spasms for several years. However, the use of steroids in the treatment of epilepsy beyond infantile spasms has been limited to only a few studies. We report the experience with steroids in 32 children with intractable epilepsy, not including West syndrome. In 47%(More)

We report on a patient who presented at 5 years of age with a hemiparesis due to a middle cerebral artery infarction. An embolism had originated from a mycotic aneurysm located in the internal carotid artery. For several months prior to admission he had been suffering from therapeutically resistant candidiasis of the mouth and nails. Family history revealed(More)
The cardiofaciocutaneous (CFC) syndrome is characterized by congenital heart defect, developmental delay, peculiar facial appearance with bitemporal constriction, prominent forehead, downslanting palpebral fissures, curly sparse hair and abnormalities of the skin. CFC syndrome phenotypically overlaps with Noonan and Costello syndromes. Mutations of several(More)
TMEM70 deficiency is the most common nuclear-encoded defect affecting the ATP synthase. In this multicentre retrospective study we characterise the natural history of the disease, treatment and outcome in 48 patients with mutations in TMEM70. Eleven centers from eight European countries, Turkey and Israel participated. All 27 Roma and eight non-Roma(More)
Complement regulators control the activated complement system. Defects in this homeostasis can result in tissue damage and autoimmune diseases with a heterogeneity in clinical presentation. Complement factor I (FI), a serine protease, is an important regulator of alternative pathway activation. We report a diagnostic work-up of a patient with relapsing(More)
