The cutting balloon (CB) is a specialized device designed to create discrete longitudinal incisions in the atherosclerotic target coronary segment during balloon inflation. Such controlled dilatation theoretically reduces the force needed to dilate an obstructive lesion compared with standard percutaneous transluminal coronary angioplasty (PTCA). We report a multicenter, randomized trial comparing the incidence of restenosis after CB angioplasty versus conventional balloon angioplasty in 1,238 patients. Six hundred seventeen patients were randomized to CB treatment, and 621 to PTCA. The mean reference vessel diameter was 2.86 +/- 0.49 mm, mean lesion length 8.9 +/- 4.3 mm, and prevalence of diabetes mellitus in patients was 13%. The primary end point, the 6-month binary angiographic restenosis rate, was 31.4% for CB and 30.4% for PTCA (p = 0.75). Acute procedural success, defined as the attainment of <50% diameter stenosis without in-hospital major adverse cardiac events, was 92.9% for CB and 94.7% for PTCA (p = 0.24). Freedom from target vessel revascularization was slightly higher in the CB arm (88.5% vs 84.6%, log-rank p = 0.04). Five coronary perforations occurred in the CB arm only (0.8% vs 0%, p = 0.03). At 270 days, rates of myocardial infarction, death, and total major adverse cardiac events for CB and PTCA were 4.7% versus 2.4% (p = 0.03), 1.3% versus 0.3% (p = 0.06), and 13.6% versus 15.1% (p = 0.34), respectively. In summary, the proposed mechanism of controlled dilatation did not reduce the rate of angiographic restenosis for the CB compared with conventional balloon angioplasty. CB angioplasty should be reserved for difficult lesions in which controlled dilatation is believed to provide a better acute result compared with balloon angioplasty alone.

A central result in the theory of integer optimization states that a system of linear diophantine equations Ax = b has no integral solution if and only if there exists a vector in the dual lattice, yT A integral such that yT b is fractional. We extend this result to systems that both have equations and inequalities {Ax = b, C x ≤ d}. We show that a certificate of integral infeasibility is a linear system with rank(C) variables containing no integral point. The result also extends to the mixed integer setting. [less ▲]

In this talk, we generalize the concept of a split (that leads to split cuts) to any lattice-point-free polyhedron. We show how we can generate cutting planes for a polyhedron from these objects. Associated to any lattice-point-free polyhedron, we define a "split-dimension" (which is equal to 1 in the case of a split in the usual sense). We then consider the operation of adding to a polyhedron all cutting planes that we can obtain from considering all the lattice-point-free polyhedra with a split-dimension lower or equal to d. We call the obtained object the "d-dimensional split closure" of the initial polyhedron. We discuss whether this object is again a polyhedron or not. As an important illustration, we focus on objects of split-dimension equal to 1 or 2. [less ▲]

The auxin and phenolic contents, as well as phenylalanine ammonia-lyase (PAL) activity, were determined in in vitro cultured shoots of the recalcitrant-to-root rac mutant of tobacco, and compared with wild-type shoots. The mutant and wild-type shoots showed similar auxin changes during the culture cycle, but with higher contents for the mutant. A transient peak of auxin (corresponding to the achievement of the rooting inductive phase) occurred at day 14 in both types of shoots, but earlier in the basal parts of the wild-type stems. The rac shoots contained more phenolics, corresponding with an increased PAL activity. The most abundant phenolic compound found in the two types of tobacco was chlorogenic acid, which was more abundant in the rac shoots. Rutin was also detected at a higher concentration in the mutant shoots. Basal parts of wild-type shoots treated with 10(-3) chlorogenic acid reacted by accumulating auxins and, unlike untreated controls, did not form adventitious roots. The relationships between those biochemical analyses in relation to the growth limitation of the rac mutant, and the inhibition of its root development, are discussed. [less ▲]

Tomato (Lycopersicon esculentum) mitochondria contain both alternative oxidase (AOX) and uncoupling protein as energy-dissipating systems that can decrease the efficiency of oxidative phosphorylation. We followed the cyanide (CN)-resistant, ATP-synthesis-sustained, and uncoupling-protein-sustained respiration of isolated mitochondria, as well as the immunologically detectable levels of uncoupling protein and AOX, during tomato fruit ripening from the mature green stage to the red stage. The AOX protein level and CN-resistant respiration of isolated mitochondria decreased with ripening from the green to the red stage. The ATP-synthesis-sustained respiration followed the same behavior. In contrast, the level of uncoupling protein and the total uncoupling-protein-sustained respiration of isolated mitochondria decreased from only the yellow stage on. We observed an acute inhibition of the CN-resistant respiration by linoleic acid in the micromolar range. These results suggest that the two energy-dissipating systems could have different roles during the ripening process. [less ▲]
