BACKGROUND External wrapping is a surgical technique performed in patients with a dilated ascending aorta. The aim of this study is to present the mid-term results of wrapping of the dilated ascending aorta. METHODS 34 patients (mean age: 64.4 ± 10.8 years, 21 males) with a dilated ascending aorta were operated on at a single cardiac surgery center using a wrapping technique. The aortas were ...

We study the level and severity of asset poverty, the characteristics of asset-poor households, the trends and persistence of asset poverty, and the role of major lifetime events affecting transitions in and out of asset poverty. We find that, contrary to a sharp decline in the official measure of poverty, which is based on income, the asset poverty rate barely changed over the 1984–99 period a...

Demain, A. L. (Merck Sharp & Dohme Research Laboratories, Rahway, N.J.), I. M. Miller, and D. Hendlin. Production of extracellular guanosine-5'-monophosphate by Bacillus subtilis. J. Bacteriol. 88:991-995. 1964.-Wild-type Bacillus subtilis colonies were found to feed purineless mutants. A strain with high feeding capacity was selected for study, with a guanineless mutant of B. subtilis used as ...

We report high resolution simultaneous measurements of electrical conductance and force gradient between two sharp gold tips as their separation is varied from the tunneling distance to atomic-size contact. The use of atomically sharp tips minimizes van der Waals interaction, making it possible to identify the short-range metallic adhesion contribution to the total force.

The monotypic genus Linoderus Sharp, 1885 was described based on a species from Panama and since the original description nearly nothing has been added to its taxonomical knowledge. The aim of the present paper is to describe a new species of the genus from Colombia and to report the genus for the first time from South America, adding some biological notes of the species.

The metabolism and disposition of statins are highly dependent on different cytochrome P450 enzymes, such as CYP3A4 and CYP2C9, as well as membrane transporters SLCO1B1, SLCO2B1, ABCB1, and ABCG2. Interindividual gene expression differences among these enzymes may explain part of the variability in tolerance and effect for statin treatment. The aim of the present study was to investigate the ef...

Wall and Shortland (1991) have shown that afferent fibers entering the cord in thoracic and lumbar roots of adult rats have branches that may penetrate up to 11 segments caudally from the root entry zone. We have investigated the extent of branching and conduction velocities of ascending and descending branches of lumbar and thoracic primary afferents in isolated spinal cords of adult hamsters ...
