The R6/2 mouse possesses mutant exon 1 of human Hdh, and R6/2 mice with 150 CAG repeats show neurological abnormalities by 10 weeks and die by 15 weeks. Few brain abnormalities, however, are evident at death, other than widespread ubiquitinated neuronal intranuclear inclusions (NIIs). We constructed R6/2t+/t- <--> wildtype (WT) chimeric mice to prolong(More)
This paper focuses on the numerical investigation of low-voltage arc plasma behaviour with the contact opening process included. A flexible experimental setup with a rotating contact is designed to support this study. Based on the magnetohydrodynamic arc model, the elongation and the commutation behaviour of the arc plasma during the contact rotation(More)
Two regions were recently recognized as subpallial amygdaloid nuclei in birds, the nucleus taeniae of the amygdala (TnA) and the newly identified subpallial amygdala (SpA). Here we further confirm these nuclei to be subpallial and amygdaloid and show similarity to specific mammalian subpallial amygdaloid nuclei. By its topological, connectional and(More)
Phenocopies of Huntington's disease (HD) are individuals with a family history, clinical symptoms, and occasionally pathological evidence of HD but without an expanded CAG repeat within the HD gene. We report on an HD phenocopy with selective loss of preprotachykinin (PPT) neurons, dysfunction of surviving PPT neurons, preservation of preproenkephalin (PPE)(More)
Bacterial H-NS forms nucleoprotein filaments that spread on DNA and bridge distant DNA sites. H-NS filaments co-localize with sites of Rho-dependent termination in Escherichia coli, but their direct effects on transcriptional pausing and termination are untested. In this study, we report that bridged H-NS filaments strongly increase pausing by E. coli RNA(More)
We study eye gaze movement behavior during paper reading and generate a series of annotations from a user's reading features: gray shading to indicate reading speed, borders to indicate frequency of re-reading, and lines to indicate transitions between sections of a document. Through a user study, we validate that our SocialReading system that shares(More)
Many terpenoids have important pharmacological activity and commercial value; however, application of these terpenoids is often limited by problems associated with the production of sufficient amounts of these molecules. The use of Saccharomyces cerevisiae (S. cerevisiae) for the production of heterologous terpenoids has achieved some success. The objective(More)
In this study, folic-dextran-camptothecin (Fa-DEX-CPT) tumor-targeted nanoparticles were produced with a supercritical antisolvent (SAS) technique by using dimethyl sulfoxide (DMSO) as a solvent and carbon dioxide as an antisolvent. A factorial design was used to reveal the effect of various process parameters on the mean particle size (MPS) and morphology(More)
The HIV-1 restriction factor SAMHD1 is a tetrameric enzyme activated by guanine nucleotides with dNTP triphosphate hydrolase activity (dNTPase). In addition to this established activity, there have been a series of conflicting reports as to whether the enzyme also possesses single-stranded DNA and/or RNA 3'-5' exonuclease activity. SAMHD1 was purified using(More)
