Some DNA oligonucleotides can fold back and self-associate forming dimeric structures stabilized by intermolecular base pairs. The resulting antiparallel dimer is a tightly packed four-stranded structure formed by a core of minor groove tetrads connected by short loops of unpaired nucleotides. We have explored the sequential requirements for the loop ...

In this paper, a novel core-modified porphyrin with meso-aryl substituents and phenanthrene-fused pyrrole rings (N2S2-OR) is synthesized. Scanning tunneling microscopy (STM) has been used to probe its self-assembly behavior on a highly-oriented pyrolytic graphite (HOPG) surface. Our STM results have shown that there is an obvious solvent-dependent self-assembly for the ...

Background: Transthoracic (TTE) and intracardiac echocardiography (ICE) have both been established as modalities for imaging guidance in mitral balloon valvuloplasty (MBV). Real-time 3-dimensional transesophageal echocardiography (RT3D-TEE) improves depth resolution, characterization of pathology and visualization of interventional catheters and devices. Three-dimensional imaging should enhance catheter navigation but improvements in procedural outcomes ...

In the present study we used a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced Parkinson's disease (PD) mouse model to analyze resveratrol neuroprotective effects. The MPTP-induced PD model is characterized by chronic inflammation, oxidative stress and loss of the dopaminergic (DA) neurons in the substantia nigra pars compacta (SNpc). We observed that resveratrol treatment significantly ...

Hemophilia A (HA) and hemophilia B (HB) are X-linked, recessive disorders. Although their clinical manifestations are essentially indistinguishable, it has been suggested that bleeding episodes in patients with HA are generally more severe and occur at higher frequency than in patients with HB. Nevertheless, considerable debate remains regarding the relative ...
