Polydopamine Integrated Nanomaterials and Their Biomedical Applications.

In the past few decades, the applications of nanomaterials in biologic systems have become one of the most studied areas. Many novel syntheses and processing methods have been developed to generate nanomaterials to enhance biomedical applications. Among those methods, polydopamine (PDA) integrated nanomaterials have attracted considerable interest for various types of biomedical applications.

Photoluminescence of carbon nanodots: dipole emission centers and electron-phonon coupling.

Inorganic carbon nanomaterials, also called carbon nanodots, exhibit a strong photoluminescence with unusual properties and, thus, have been the focus of intense research. Nonetheless, the origin of their photoluminescence is still unclear and the subject of scientific debates. Here, we present a single particle comprehensive study of carbon nanodot photoluminescence, which combines emission and lifetime spectroscopy, defocused emission dipole imaging, azimuthally polarized excitation dipole scanning, nanocavity-based quantum yield measurements, high resolution transmission electron microscopy, and atomic force microscopy.

Single-molecule metal-induced energy transfer (smMIET): resolving nanometer distances at the single-molecule level.

We present a new concept for measuring distance values of single molecules from a surface with nanometer accuracy using the energy transfer from the excited molecule to surface plasmons of a metal film. We measure the fluorescence lifetime of individual dye molecules deposited on a dielectric spacer as a function of a spacer thickness. By using our theoretical model, we convert the lifetime values into the axial distance of individual molecules.

Resolution doubling in fluorescence microscopy with confocal spinning-disk image scanning microscopy.

We demonstrate how a conventional confocal spinning-disk (CSD) microscope can be converted into a doubly resolving image scanning microscopy (ISM) system without changing any part of its optical or mechanical elements. Making use of the intrinsic properties of a CSD microscope, we illuminate stroboscopically, generating an array of excitation foci that are moved across the sample by varying the phase between stroboscopic excitation and rotation of the spinning disk. ISM then generates an image with nearly doubled resolution.

Clinical differences between total PAPP-A and measurements specific for the products of free PAPP-A activity in patients with stable cardiovascular disease.

Objectives: We have previously reported that increases in total pregnancy-associated plasma protein-A (PAPP-A) which are thought to be indicative of vulnerable plaques and thus poor outcomes predict outcomes in patients with stable coronary artery disease. We hypothesized that the determination of CT- and NT-fragments of insulin-like growth factor binding protein 4 (CT- and NT-IGFBP4) which should be indicative of free PAPP-A would result in better performance.

Methods: In 229 stable cardiovascular patients with indication for heart catheterization after performance of a stress test and an echocardiogram, CT- and NT-IGFBP4 were measured.

Exercise tolerance in asymptomatic patients with moderate-severe valvular heart disease and preserved ejection fraction.

Introduction: For asymptomatic patients with moderate-severe valvular heart disease, in whom symptoms may be obscured, objective exercise tolerance measures are warranted for decisions concerning physical activities and surgical treatment.

Material And Methods: We compared 61 patients (39 with aortic stenosis, 22 with aortic or mitral regurgitation) to 23 controls without valvular heart disease but with indications for stress testing. All participants underwent cardiopulmonary function testing and dobutamine stress echocardiography.

Aortic valve replacement in asymptomatic and symptomatic patients with preserved left ventricular ejection fraction.

Background And Aim Of The Study: Patients with moderate-severe aortic stenosis (AS) who maintain that they have no symptoms pose a decision-making dilemma. In order to determine whether or not preoperative symptoms were related to outcomes in these patients, results were compared after aortic valve replacement (AVR) in asymptomatic and symptomatic AS patients with a preserved left ventricular ejection fraction (LVEF).

Methods: Twenty asymptomatic and 18 symptomatic AS patients were investigated retrospectively, with clinical and echocardiographic studies being performed before and at 610 +/- 409 days after AVR.

Transparent gold as a platform for adsorbed protein spectroelectrochemistry: investigation of cytochrome c and azurin.

The majority of protein spectroelectrochemical methods utilize a diffusing, chemical mediator to exchange electrons between the electrode and the protein. In such methods, electrochemical potential control is limited by mediator choice and its ability to interact with the protein of interest. We report an approach for unmediated, protein spectroelectrochemistry that overcomes this limitation by adsorbing protein directly to thiol self-assembled monolayer (SAM) modified, thin (10 nm), semitransparent gold.

Pregnancy-associated plasma protein A values in patients with stable cardiovascular disease: use of a new monoclonal antibody-based assay.

Background: PAPP-A is promising in improving risk stratification and invasive treatment decisions in stable cardiovascular patients. We evaluated the prognostic value of pregnancy-associated plasma protein A (PAPP-A) measured by a novel assay in stable cardiovascular patients.

Methods: We investigated 228 stable cardiovascular outpatients.

Influence of acute and chronic myocardial loading conditions, function, structural changes and extracardiac factors on NT-proBNP in asymptomatic patients with preserved ejection fraction.

Background: We compared the effect of different loading conditions, parameters of structural heart disease and extracardiac confounders on NT-proBNP to validate the application of NT-proBNP for a characterisation of loading conditions and clinical course of patients with chronic heart diseases.

Methods: NT-proBNP was measured in 15 controls and 34 patients with preserved ejection fraction and chronic pressure (by aortic stenosis) or volume overload (by aortic or mitral regurgitation) before and after physical as well as dobutamine stress. Myocardial fibrosis was evaluated by contrast-enhanced cardiovascular magnetic resonance.

Aqueous synthesis of zinc blende CdTe/CdS magic-core/thick-shell tetrahedral-shaped nanocrystals with emission tunable to near-infrared.

We demonstrate the synthesis of near-IR-emitting zinc blende CdTe/CdS tetrahedral-shaped nanocrystals with a magic-sized (approximately 0.8 nm radius) CdTe core and a thick CdS shell (up to 5 nm). These high-quality water-soluble nanocrystals were obtained by a simple but reliable aqueous method at low temperature.

High-sensitive cardiac troponin I (hs-cTnI) values in patients with stable cardiovascular disease: an initial foray.

Background: How to use the information from novel high sensitivity troponin assays in stable cardiac patients is unclear. Preliminary data from randomized controlled trial analyses suggest it helps with risk stratification. We investigated the determinants, diagnostic impact and prognostic value of a novel high-sensitive cardiac troponin I (hs-cTnI) assay in patients with stable cardiac disease.

[Recent assay developments for cardiac troponins: are we sensitive enough to recognize the high sensitives?].

Cardiac troponins play a major role in the diagnostic work-up of acute coronary syndrome/myocardial infarction. Elevations were demonstrated also in other, rather nonischemic diseases like pulmonary embolism or acute heart failure. Stepwise improvement in the accuracy of the commercially available assays allowed detection of low-level concentrations of cardiac troponins, which were previously partially classified to be normal (between the limit of detection and the 99 th percentile by < 10% coefficient of variance).

Usefulness of detectable levels of troponin, below the 99th percentile of the normal range, as a clue to the presence of underlying coronary artery disease.

The aim of the study was to evaluate whether markers of myocardial injury and ischemia are helpful in detecting coronary artery disease (CAD) in patients with stable angina. Venous blood was obtained before and after a bicycle exercise test in 47 outpatients with suspected CAD for measurement of cardiac troponin I (cTnI), heart-type fatty acid binding protein, and glycogen phosphorylase BB. Patients with a coronary artery stenosis >/=70% in diameter (n = 33) were compared with patients with coronary narrowing <50% (controls, n = 14).
