Differentiation of Tumors of the Upper Respiratory Tract Using Optical Metabolic Imaging.

Objectives: With over 184,000 new cases and more than 99,000 deaths per year, malignancies of the larynx are a global health problem. Currently, a dedicated screening method enabling a direct onsite diagnosis is missing. This can lead to delayed diagnosis and worse outcomes of the patients.

Probing the ultrafast dynamics of excitons in single semiconducting carbon nanotubes.

Excitonic states govern the optical spectra of low-dimensional semiconductor nanomaterials and their dynamics are key for a wide range of applications, such as in solar energy harvesting and lighting. Semiconducting single-walled carbon nanotubes emerged as particularly rich model systems for one-dimensional nanomaterials and as such have been investigated intensively in the past. The exciton decay dynamics in nanotubes has been studied mainly by transient absorption and time-resolved photoluminescence spectroscopy.

Second-versus first-generation "Limus"-eluting stents in diabetic patients with coronary artery disease: a randomized comparison in setting of ISAR-TEST-4 trial.

Background: Patients with diabetes mellitus remain at higher risk for adverse events following percutaneous coronary intervention and the identification of the optimum drug eluting stents (DES) in these patients is of high clinical relevance. We compared effectiveness of everolimus-eluting stents (EES; Xience) versus sirolimus-eluting stents (SES; Cypher) in patients with diabetes mellitus enrolled in the Intracoronary Stenting and Angiographic Results: Test Efficacy of 3 Limus-Eluting Stents (ISAR-TEST-4) trial.

Methods: In the setting of the ISAR-TEST-4 trial, 1304 patients with broad inclusion criteria were randomized to treatment with EES or SES.

One-year outcomes with abciximab and unfractionated heparin versus bivalirudin during percutaneous coronary interventions in patients with non-ST-segment elevation myocardial infarction: updated results from the ISAR-REACT 4 trial.

Aims: Thirty-day results of the double-blind, randomised Intracoronary Stenting and Antithrombotic Regimen -Rapid Early Action for Coronary Treatment (ISAR-REACT) 4 trial showed no difference in ischaemic complications and a reduction in bleeding by bivalirudin versus abciximab and heparin in 1,721 patients with non-ST-segment elevation myocardial infarction (NSTEMI) undergoing percutaneous coronary intervention (PCI). A longer follow-up may be required to assess the whole potential benefit of a periprocedural antithrombotic therapy.

Methods And Results: The primary outcome for this analysis was the composite of death, myocardial infarction or target vessel revascularisation one year after randomisation.

Association of uric acid with mortality in patients with stable coronary artery disease.

Objective: The association between uric acid and cardiovascular disease is poorly studied. We undertook this study to assess whether uric acid level predicts clinical outcome in patients with stable coronary artery disease (CAD) treated with percutaneous coronary intervention (PCI).

Materials/methods: This study included 8149 patients with stable CAD who underwent PCI.
