What can lattice DFT teach us about real-space DFT?

In this paper we establish a connection between density functional theory (DFT) for lattice models and common real-space DFT. We consider the lattice DFT description of a two-level model subject to generic interactions in Mermin's DFT formulation in the grand canonical ensemble at finite temperature. The case of only density-density and Hund's rule interaction studied in earlier work is shown to be equivalent to an exact-exchange description of DFT in the real-space picture.

Long-term prognostic value of endothelial dysfunction in patients with chest pain and angiographically normal coronary arteries.

Objective: To evaluate the prognostic impact of endothelial function in patients with angina and angiographically normal coronary arteries.

Methods: In 147 consecutive patients with angina and normal coronary arteries on coronary angiography, we studied endothelial function by incremental intracoronary bolus of acetylcholine (ACh). Patients were divided in two groups according to their vasomotor response to ACh: 1) ACh+ group (n = 95), those with diffuse vasoconstriction during ACh administration; and 2) ACh- group (n = 52): those showing normal endothelial function.

[Budd-Chiari syndrome with complete occlusion of the inferior vena cava: percutaneous recanalization by angioplasty and stenting].

A 47-year-old man was diagnosed with primary antiphospholipid syndrome and Budd-Chiari syndrome (membranous complete obstruction of the intrahepatic inferior vena cava), with edema and ascites refractory to medical treatment. The inferior vena cava membrane was punctured with a Brockenbrough needle under multidirectional fluoroscopic guidance via a transfemoral approach. The occlusion was dilated with balloons of increasing size and was subsequently stented successfully.

[Use of a combination of enoxaparin or unfractionated heparin and abciximab during percutaneous coronary interventions: a randomized pilot study].

Objectives: The cumulative experience gleaned from the NICE trials suggests that adjunctive enoxaparin therapy for percutaneous transluminal coronary angioplasty (PTCA), with or without concomitant abciximab therapy, is both safe and effective. However, no randomized studies have been conducted to compare the two strategies. The aim of this study was to evaluate the safety of combined enoxaparin-abciximab compared with standard therapy using unfractionated heparin and abciximab.

[Variable response to the biological inhibition of platelets by abciximab in patients subjected to percutaneous coronary angioplasty].

Introduction And Objectives: Abciximab has been shown to reduce the risk of thrombotic complications during coronary angioplasty, however there are still many aspects to be resolved. The aim of this study was to investigate the various biological effects of abciximab on platelets during coronary angioplasty.

Methods: The degree of platelet inhibition (with 5 and 20 mol/l concentrations of ADP), occlusion time (measurement of platelet haemostatic capacity, PFA-100), and the platelet activation markers were determined in 15 patients who underwent basal coronary angioplasty and abciximab treatment.
