Prescription of platelet inhibitors after arterial surgery is common use. The major concern of the vascular surgeon is to maintain patency of arterial reconstructions. Major causes of graft failure or arterial thrombosis are the non-thromboresistant nature of the grafts and of the endarterectomised or balloon-dilated surfaces, restenosis due to intimal hyperplasia and progression of atherosclerotic disease in in- or outflow vessels. Platelet adhesion and intimal injury are the primary causes in both processes of graft thrombosis and intimal hyperplasia. To understand how antiplatelet drugs can interfere with these processes, a brief review of platelet function, and of the main platelet inhibitors (aspirin, dypiridamole, ticlopidine) is given. The pathophysiology of intimal hyperplasia is discussed. From clinical trials of peripheral vascular surgery or percutaneous transluminal angioplasty with or without periprocedural antiplatelet therapy, it appears that platelet inhibitors reduce early failure rate by 50% (thrombosis rate at one year reduced from 40 to 20%). There is also evidence that antiplatelet drugs allow to slow down the progression of the atherosclerotic degenerative process in the outflow vessels and in other vascular territories. For the polyvascular patients with charged passed history, platelet inhibitors reduce the risk of myocardial or cerebral infarction by 30% (secondary prevention). Today, there is a general consensus that antiplatelet drugs, started the day before the procedure, are beneficial for early and late patency of peripheral vascular reconstructions (carotid endarterectomy, infrainguinal bypass grafts or endovascular procedures).

The capacity of UDP-N-acetyl-alpha-D-glucosamine (UDP-GlcNAc) as an in vitro acceptor substrate for beta-1,4-galactosyltransferase (beta4GalT1, EC 2.4.1.38) from human and bovine milk and for recombinant human beta4GalT1, expressed in Saccharomyces cerevisiae, was evaluated. It turned out that each of the enzymes is capable to transfer Gal from UDP-alpha-D-galactose (UDP-Gal) to UDP-GlcNAc, affording Gal(beta1-4)GlcNAc(alpha1-UDP (UDP-LacNAc). Using beta4GalT1 from human milk, a preparative enzymatic synthesis of UDP-LacNAc was carried out, and the product was characterized by fast-atom bombardment mass spectrometry and 1H and 13C NMR spectroscopy. Studies with all three beta4GalTs in the presence of alpha-lactalbumin showed that the UDP-LacNAc synthesis is inhibited and that UDP-alpha-D-glucose is not an acceptor substrate. This is the first reported synthesis of a nucleotide-activated disaccharide, employing a Leloir glycosyltransferase with a nucleotide-activated monosaccharide as acceptor substrate. Interestingly, in these studies beta4GalT1 accepts an alpha-glycosidated GlcNAc derivative. The results imply that beta4GalT1 may be responsible for the biosynthesis of UDP-LacNAc, previously isolated from human milk. [less ▲]

An unusual temperature and concentration behavior of the resistivity ρ(T,x) in La0.7Ca0.3Mn1-xCuxO3 is observed at slight Cu doping (0 ≤x≤ 0.05). Namely, the introduction of copper results in a splitting of the resistivity maximum around the metal-insulator transition temperature T0(x) into two differently evolving peaks. Unlike the original Cufree maximum, which steadily increases with doping, the second (satellite) peak remains virtually unchanged for x<xc, increases for x≥xc, and finally disappears at xm ≃ 2xc, with xc ≃ 0.03. The observed phenomenon is thought to arise from a competition between substitution-induced strengthening of the potential barriers (which hinder the charge hopping between neighboring Mn sites) and weakening of the kinetic energy of the carriers. The data are well fitted by assuming a nonthermal tunneling conductivity theory with randomly distributed hopping sites. © 1999 American Institute of Physics. [less ▲]

The technique and the results of the external contention of the dilated ascending aorta by the application of an external Dacron graft are reported. This technique, without replacing the usual graft interposition, can efficiently and expeditiously treat borderline dilatation of the ascending aorta, as frequently encountered in aortic valve disease. If the sinotubular junction is not dilated, this technique may stop the aneurysmal evolution of the ascending aorta. [less ▲]

OBJECTIVES: To evaluate, in an elderly population, whether poor oral status might be a contributing factor to the development of undernutrition and might be associated with less eating pleasure, more subjective eating difficulty and increased mashed food consumption. METHODS: An oral examination and an evaluation of masticatory capacity were performed on 120 institutionalized elderly subjects. The nutritional assessment included serum albumin concentration, the Mini Nutritional Assessment and a questionnaire on eating habits. RESULTS: Edentulous subjects without dentures or with only one complete denture had significantly lower MNA scores than edentulous subjects with two complete dentures (p < 0.05). Edentulous subjects with two complete dentures more frequently reported taking pleasure from eating (p = 0.05), and had less frequent difficulties with hard foods (p = 0.01) than edentulous subjects without dentures or with only one complete denture. Mashed food consumption (p < 0.01) was also reported more frequently in edentulous subjects without dentures or with only one complete denture. Subjects with two complete dentures had similar or better MNA scores as dentate subjects with relatively few remaining teeth (10.4 +/- 7.8 teeth). About half of the subjects (53%) could not perform the masticatory test. These subjects had lower MNA scores (p = 0.001) and a larger proportion ate mashed food (p < 0.001) compared to those who were able to perform the test. CONCLUSIONS: Poor oral status (edentulous without dentures or with only one complete denture) increased difficulty in eating hard foods, increased mashed food consumption and decreased eating pleasure. It seemed also to put institutionalized subjects at higher risk of undernutrition. [less ▲]
