Protein misfolding is considered a key event in the pathogenesis of polyglutamine disease such as Machado-Joseph disease (MJD). Overexpression of chaperone proteins and the application of chemical chaperones are reported to suppress polyglutamine induced cytotoxicity in vitro and in vivo. The effects of compatible solutes, which are osmoprotectants in(More)
The pons is one of the brain areas demonstrating selective degeneration in Machado-Joseph disease (MJD), which is caused by the expansion of a polyglutamine stretch in the protein called ataxin-3. Although the resultant pontine atrophy is readily recognized by magnetic resonance imaging (MRI), the features and natural process of atrophy are not fully(More)
The expression of alpha-dystrobrevin and dystrophin in rat tibialis anterior muscles was chronologically evaluated during a cycle of regeneration after myonecrosis induced by the injection of cardiotoxin. In immunohistochemical studies, alpha-dystrobrevin and dystrophin were first stained weakly at the sarcolemma of some regenerating muscle fibers on day 5.(More)
Coordinated development of excitatory and inhibitory synapses is crucial for normal function of neuronal circuits. Using homo- and heterochronic cultures of hippocampal neurons, we compared the formation of glutamatergic and GABAergic synapses at different stages and asked whether the age of dendrites affects their ability to accept new glutamatergic and(More)
When reading sentences with an anaphoric reference to a subject antecedent, repeated-name anaphors result in slower reading times relative to pronouns (the Repeated Name Penalty: RNP), and overt pronouns are read slower than null pronouns (the Overt Pronoun Penalty: OPP). Because in most languages previously tested, the grammatical subject is typically also(More)
