We here report for the first time the synergistic implementation of structured illumination microscopy (SIM) and multifocus microscopy (MFM). This imaging modality is designed to alleviate the problem of insufficient volumetric acquisition speed in super-resolution biological imaging. SIM is a wide-field super-resolution technique that allows imaging with visible light beyond the classical diff...

Three-dimensional structured illumination microscopy (3D-SIM) is a versatile and accessible method for super-resolution fluorescence imaging, but generating high-quality data is challenging, particularly for non-specialist users. We present SIMcheck, a suite of ImageJ plugins enabling users to identify and avoid common problems with 3D-SIM data, and assess resolution and data quality through ob...

The aim of the present study was to determine the pharmacokinetics of simvastatin (SIM) administered orally in 6-week-old turkeys at a single dose of 2 mg/kg b.w. The SIM concentrations in plasma were determined by validated HPLC-MS/MS method. Mean (+/- SD; n = 10) values of pharmacokinetic parameters evaluated were as follows: Cmax = 0.49 +/- 0.21 ng/ml, t(max) = 1.6 +/- 1.1 h, AUC(0-infinity)...

BACKGROUND Transforming growth factor-β1 (TGF-β1)-induced epithelial-mesenchymal transition (EMT) of alveolar epithelial cells (AEC) may contribute to idiopathic pulmonary fibrosis (IPF). TGF-β1-induced EMT in A549 cells (a human AEC cell line) resulted in the adoption of mesenchymal responses that were predominantly mediated via the TGF-β1-Smad2/3 signaling pathway. Simvastatin (Sim), a 3-hydr...

Tradeoffs between data-acquisition time, label and specimen viability, resolution and signal-tonoise ratio (SNR), and reduction of possible aberrations exist among different types of fluorescence microscopes. Widefield (WF) microscopy remains the optimal methodology for gathering the most photons efficiently. This property of WF microscopy is exploited in both computational optical-sectioning m...

The paper presents the C-Sim simulation tool that enables an experimental evaluation (i.e. testing) of parallel and distributed programs behavior using their close-toreality C-language source code and a simulated operational environment. 1. Simulation based method of parallel programs testing The method uses discrete-time process-oriented simulation model of a parallel or distributed computer s...

In directed graphs, relationships are asymmetric and these asymmetries contain essential structural information about the graph. Directed relationships lead to a new type of clustering that is not feasible in undirected graphs. We propose a spectral co-clustering algorithm called di-sim for asymmetry discovery and directional clustering. A Stochastic co-Blockmodel is introduced to show favorabl...
