friedreich ataxia/hypoxia

Friedreich's ataxia (FRDA) is a devastating, multisystemic disorder caused by recessive mutations in the mitochondrial protein frataxin (FXN). FXN participates in the biosynthesis of Fe-S clusters and is considered to be essential for viability. Here we report that when grown in 1% ambient

Aspergillus fumigatus is an opportunistic, airborne pathogen that causes invasive aspergillosis in immunocompromised patients. During the infection process, A. fumigatus is challenged by hypoxic microenvironments occurring in inflammatory, necrotic tissue. To gain further insights into the

Mutations in gene products expressed in the mitochondrion cause a nuclear transcriptional response that leads to neurological disease. To examine the extent to which the transcriptional profile was shared among 5 mitochondrial diseases (LHON, FRDA, MELAS, KSS, and NARP), we microarrayed mutant and

The BiPAP-System is a useful ventilatory support for patients with severe sleep apnea and need for high inspiratory pressure. Using the BiPAP as a full ventilatory support is new due to the recent addition of a timed control modus and individual control of inspiratory time. We used the new BiPAP

Friedreich's Ataxia (FRDA) is a neurodegenerative disorder, characterized by degeneration of dorsal root ganglia, cerebellum and cardiomyopathy. Heart failure is one of the most common causes of death for FRDA patients. Deficiency of frataxin, a small mitochondrial protein, is responsible for all

This chapter summarizes the neuropathologic features of nonneoplastic disorders of the adult cerebellum. Gait ataxia and extremity dysmetria are clinical manifestations of diseases that interrupt the complex cerebellar circuitry between the neurons of the cerebellar cortex, the cerebellar nuclei

Friedreich's ataxia (FRDA) is an autosomal recessive neurodegenerative disease caused by reduced expression of the mitochondrial protein frataxin (FXN). Most FRDA patients are homozygous for large expansions of GAA repeat sequences in intron 1 of FXN, while a fraction of patients are compound
