The synthesis of a seven-membered ring locked analogue of 11-cis-retinol, tethered to a cross-linking moiety on C-15 and a lysine-extended biotin on the C-3, was accomplished for its utilization as a probe to fish out retinol binding proteins that may be involved in the reisomerization of retinal from all-trans to 11-cis in the visual cycle.

This study determined the shear bond strength of resin composites to primary dentin using three dentin adhesives and the presence or absence of a hybrid zone. The buccal and lingual surfaces of 40 recently extracted noncarious primary teeth were ground flat with SiC paper ending with the 600 grit. The teeth were divided at randomly into eight groups of five teeth (10 surfaces) each: 1) Unetched...

BACKGROUND The effect of moderate left ventricular systolic dysfunction (LVSD) on ventricular/vascular coupling and the aortic pressure waveform (AoPW) has been well described, but the effect of severe LVSD has not. METHODS AND RESULTS We used noninvasive, high-fidelity tonometry of the radial artery and a mathematical transfer function to generate the AoPW in 25 treated patients with LVSD (m...

Complete right bundle branch block manifests with a rSR' configuration in right orientated leads and a duration of 0.12 sec or longer. Incomplete right bundle branch block is perceived as this classic rSr' configuration and a duration of less than 0.12 sec. This presentation reflects the early development of right bundle branch block which first manifests with a hitherto undescribed sign, namel...

[Purpose] The aim of this study was to collect basic data on the effect of asymmetry on the muscle strength of the left and right knee and ankle joints of soccer players at varying athletic performance levels, to guide the development of improved exercise programs. [Subjects and Methods] Forty-nine soccer players at three athletic performance levels participated: 15 professional, 16 amateur, an...

Experience in real-world listening situations suggests that listeners, in general, have a great deal of spatial information about multiple concurrent sounds in an auditory scene. Despite this, laboratory data would suggest that listeners should operate quite poorly in such environments. This study employed environmental sounds that would naturally occur in real-world auditory environments and m...
