the stereochemistry of the actinide elements has recently undergone considerable development and a wide variety of coordination numbers and geometries have been observed. this structural versatility arises from the lack of strong crystal field effects for the 5f-electronic configurations as well as from the large ionic radii of these metal ions, which change markedly with oxidation number, or a...

Huntington's disease (HD) is a progressive neurodegenerative disease caused by an unstable CAG trinucleotide repeat expansion. The need for biomarkers of onset and progression in HD is imperative, since currently reliable outcome measures are lacking. We used two-dimensional electrophoresis and mass spectrometry to analyze the proteome profiles in cerebrospinal fluid (CSF) of 6 pairs of HD pati...

3,4-Methylenedioxymethamphetamine (MDMA or Ecstasy) is a widely abused drug. In brains of mice exposed to MDMA, we recently detected altered expression of several cDNAs and genes by using the differential display polymerase chain reaction (PCR) method. Expression of one such cDNA, which exhibited 98% sequence homology with the synaptic vesicle protein synaptotagmin IV, decreased 2 h after MDMA ...

Background Adenosine stress CMR with visual interpretation is increasingly used in the evaluation of patients with CAD. The definition of a stress perfusion defect is inconsistent in the literature regarding i) the duration from contrast arrival, ii) persistence relative to a remote segment, iii) transmural extent, and iv) reversibility on rest perfusion. In this study we sought to test several...

We present a comparative study on the quantum size effects in CdS and CdSe spherical dots, using first-principles derived semi-empirical pseudopotential method. Various properties including single-particle energy levels, characterization of individual electron wave functions, interband and intraband transitions, electron-hole Coulomb and exchange interactions, and excitonic band gap are investi...

OBJECTIVE The objective of this study was to describe patient experience with intravenous (IV) biologics for ankylosing spondylitis, Crohn's disease, psoriatic arthritis, psoriasis, rheumatoid arthritis, or ulcerative colitis. METHODS Semi-structured telephone interviews were conducted in 405 patients with these autoimmune diseases who were receiving an IV biologic to treat their disease. R...
