Expression of two succinyl-CoA synthetases with different nucleotide specificities in mammalian tissues.

For nearly 50 years, succinyl-CoA synthetase in animals was thought to be specific for guanine nucleotides. Recently, we purified and characterized both an ADP-forming succinyl-CoA synthetase from pigeon breast muscle and the GDP-forming enzyme from liver (Johnson, J. D.

Comparison of a silicon carbide coated stent versus a noncoated stent in humans: the Tenax- versus Nir-Stent Study (TENISS).

Purpose: Stents coated with hypothrombogenic silicon carbide (a-SiC:H) exhibited low restenosis rates in the rabbit and in an observational study in humans. Thus, the clinical and angiographic outcome was assessed in a large multicenter study.

Material And Methods: Four hundred and ninety-seven patients (63.

Comparison of a silicon carbide-coated stent versus a noncoated stent in human beings: the Tenax versus Nir Stent Study's long-term outcome.

Background: Stents coated with amorphous hypothrombogenic silicon carbide (a-SiC:H) have low restenosis rates in humans. Recurrence in a-SiC:H at mid-term follow-up has been shown to be similar to a stainless steel device. The long-term outcome, however, may be different.

Genetic evidence for the expression of ATP- and GTP-specific succinyl-CoA synthetases in multicellular eucaryotes.

Highly ATP- and GTP-specific isoforms of succinyl-CoA synthetase in pigeon incorporate the same alpha-subunit, but different beta-subunits (Johnson, J. D., Muhonen, W.

[Colonic neoplasms and skin fibromas: common determinants and their significance].

To find common factors for colonic-neoplasias and skin-tags, 157 inpatients, who consecutively had a coloscopy because of intestinal complaints, were intensively examined dermatologically. Regression-analyses showed that the number of colonic polyps were age- (p = 3 x 10(-8)) and sex-dependent (1.9 x 10(-2)) and skin-tags had no influence on the number of colonic polyps.
