In order to gain deeper insight into the functions and dynamics of RNA in cells, the development of methods for imaging multiple RNAs simultaneously is of paramount importance. Here, we describe a modular approach to image RNA in living cells using an RNA aptamer that binds to dinitroaniline, an efficient general contact quencher. Dinitroaniline quenches(More)
Phosphopantetheinyl transferases (PPTases) covalently attach the phosphopantetheinyl group derived from coenzyme A (CoA) to acyl carrier proteins or peptidyl carrier proteins as part of the enzymatic assembly lines of fatty acid synthases (FAS), polyketide synthases (PKS), and nonribosomal peptide synthetases (NRPS). PPTases have demonstrated broad(More)
We report a high-throughput phage selection method to identify mutants of Sfp phosphopantetheinyl transferase with altered substrate specificities from a large library of the Sfp enzyme. In this method, Sfp and its peptide substrates are co-displayed on the M13 phage surface as fusions to the phage capsid protein pIII. Phage-displayed Sfp mutants that are(More)
Arterial stiffness is associated with increased cardiovascular risk. Pulse wave velocity (PWV) and augmentation index (AIx) are non-invasive markers for assessment of arterial stiffness. Increased arterial stiffness is associated with atherosclerosis in patients with psoriasis. Previous studies have shown that high neutrophil-to-lymphocyte ratio (NLR)(More)
BACKGROUND AND AIM OF THE STUDY The neutrophil-to-lymphocyte ratio (NLR) is an independent predictor of poor prognosis in different clinical conditions such as infectious and cardiovascular diseases. It was hypothesized that a patient's admission NLR would be predictive of an adverse clinical outcome in cases of infective endocarditis (IE). METHODS A(More)
BACKGROUND Systemic sclerosis (SSc) is a systemic connective tissue disease and cardiac involvement is one of the most important causes of death. Right ventricular (RV) systolic dysfunction is a poor prognostic finding in SSc patients. Assessment of RV function has some difficulties because of its crescent shape and extensive trabeculations. Two-dimensional(More)
OBJECTIVE Nonalcoholic fatty liver disease (NAFLD) is associated with increased risk of cardiovascular disease and impaired left ventricular (LV) function, yet the impact of NAFLD on right ventricular (RV) function remains unclear. We investigate the RV functional properties in patients with NAFLD. METHODS Ninety consecutive patients with the diagnosis of(More)
Site specific protein labeling plays a key role in elucidating the function of the proteins at the molecular level by revealing their locations in the cell, their interaction networks with other cellular components and the dynamic mechanisms of their bio-generation, trafficking and degradation in response to regulatory signals in a biological system. Site(More)
Copper, a key cofactor for many life processes, is toxic at elevated levels, and its availability is strictly controlled inside cells. Therefore, it is a challenge to visualize copper availability in the tight copper-binding environment of the cell. We report a genetically encoded fluorescent copper(I) sensor based on the copper(I)-binding-induced(More)
BACKGROUND Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) are associated with worse outcome in various diseases. Non-dipping blood pressure pattern is associated with higher cardiovascular mortality. The aim of this study was to explore the association between NLR and PLR in patients with dipper versus non-dipper hypertension.(More)
