Transradial access for balloon-assisted maturation of arteriovenous fistulas.

Balloon-assisted maturation (BAM) of arteriovenous fistulas has conventionally been performed via direct fistula access. The transradial approach has not been well described for BAM, although its use has been reported throughout the cardiology literature. The purpose of the present study was to assess the outcomes of transradial access for its use with BAM.

The mutation impairs circadian locomotor activity.

We investigated effects of mutation ap on circadian locomotor activity, eclosion rhythms, and transcript levels of and in . We investigated circadian locomotor activity and eclosion rhythms in and wild-type flies, their F1 and F2 offspring, and wingless mutants and show that disrupts circadian locomotor rhythms in a genetically recessive manner, that is not caused by the absence of wings. The strain also showed impaired circadian activity rhythms, providing independent evidence for a significant role of in circadian locomotor rhythm expression.

Stabilization and Degradation Mechanisms of Cytoplasmic Ataxin-1.

Aggregation-prone proteins in neurodegenerative disease disrupt cellular protein stabilization and degradation pathways. The neurodegenerative disease spinocerebellar ataxia type 1 (SCA1) is caused by a coding polyglutamine expansion in the Ataxin-1 gene (ATXN1), which gives rise to the aggregation-prone mutant form of ATXN1 protein. Cerebellar Purkinje neurons, preferentially vulnerable in SCA1, produce ATXN1 protein in both cytoplasmic and nuclear compartments.
