—In this letter, a novel time-domain recursive algorithm is proposed for a minimum-mean-squared error (MMSE) with successive interference cancellation (SIC) scheme. This algorithm allows us to reduce the complexity of classical MMSE-SIC equalizer for suppressing intercarrier interference (ICI) caused by time-varying multipath channels in orthogonal(More)
Cerebellar degeneration is a devastating manifestation of cerebellar-type multiple-system atrophy (MSA), a rapidly progressive neurodegenerative disease, and the exact pathogenesis is unknown. Here, we examined the expression of micro-RNAs (miRNAs), which are short noncoding RNAs, in the cerebellum of MSA and the key target genes. miRNA microarray found 11(More)
MicroRNA-206, which suppresses the expression of brain-derived neurotrophic factor, is known to be elevated in the brains of Alzheimer's disease (AD) patients. We performed intranasal biopsy of the olfactory epithelia of early dementia patients (n = 24) and cognitively healthy controls (n = 9). Patients with significant depression (n = 8) were analyzed(More)
Here, we efficiently generated transgenic cattle using two transposon systems (Sleeping Beauty and Piggybac) and their genomes were analyzed by next-generation sequencing (NGS). Blastocysts derived from microinjection of DNA transposons were selected and transferred into recipient cows. Nine transgenic cattle have been generated and grown-up to date without(More)
Inhibitory synaptic receptors are dysfunctional in epileptic brains, and agents that selectively target these receptors may be effective for the treatment of epilepsy. MicroRNAs interfere with the translation of target genes, including various synaptic proteins. Here, we show that miR-203 regulates glycine receptor-β (Glrb) in epilepsy models. miR-203 is(More)

Beta-site amyloid precursor protein cleaving enzyme 1 (BACE1) is the enzyme involved in the abnormal production of the amyloidogenic peptide Aβ, one of the major causes of histological hallmarks of Alzheimer's disease (AD). Thus, BACE1 represents a key target protein in the development of new potential target for the prevention and treatment of AD. In this(More)
Here, we studied the effect of the size, shape, and surface charge of Au nanoparticles (AuNPs) on amyloid beta (Aβ) aggregation on a total brain lipid-based supported lipid bilayer (brain SLB), a fluid platform that facilitates Aβ-AuNP aggregation process. We found that larger AuNPs induce large and amorphous aggregates on the brain SLB, whereas smaller(More)
