Fabricating Gradient Hydrogel Scaffolds for 3D Cell Culture
Authors: Kaushik Chatterjee, Marian F. Young and Carl G. SimonOptimizing cell-material interactions is critical for maximizing regeneration in tissue engineering. Combinatorial and high-throughput (CHT) methods can be used to systematically screen tissue scaffolds to identify optimal biomaterial properties. Previous CHT platforms in tissue engineering have involved a two-dimensional (2D) cell culture format where cells were cultured on material surfaces. However, these platforms are inade Read More

Procaine Effect on Human Erythrocyte Membrane Explored by Atomic Force Microscopy
The procaine effect on human erythrocytes was investigated by atomic force microscopy (AFM) at three procaine concentrations, about 5 x 10-7 M, 5 x 10-5 M and 5 x 10-4 M. The changes in surface morphology of erythrocyte membrane bring direct evidence on the procaine effect on the cell membrane at micro- and nanometer scale. AFM images of the control erythrocytes (without procaine) showed a well defined concave ( Read More

Two Panels of Steroid Receptor Luciferase Reporter Cell Lines for Compound Profiling
Authors: David Sedlak, Aileen Paguio and Petr BartunekSteroid hormone receptors represent a major target in drug discovery. As ligand inducible transcription factors, their activity can be modulated by small lipophilic molecules. Here we describe two panels of potent and selective luciferase reporter cell lines based on cells with low endogenous steroid receptor activity (U2OS). The panels contain reporter cell lines for estrogen receptors α and β, androgen, glucocorticoid, mineral Read More

Novel Affinity Ligands for Chromatography Using Combinatorial Chemistry
Spatially addressable combinatorial libraries were synthesized by solution phase chemistry and screened for binding to human serum albumin. Members of arylidene diamide libraries were among the best hits found, having submicromolar binding affinities. The results were analyzed by the frequency with which particular substituents appeared among the most potent compounds. After immobilization of the ligands either thr Read More

Chemistry Explained by Topology: An Alternative Approach
Authors: Jorge Galvez, Vincent M. Villar, Maria Galvez-Llompart and Jose M. AmigoMolecular topology can be considered an application of graph theory in which the molecular structure is characterized through a set of graph-theoretical descriptors called topological indices. Molecular topology has found applications in many different fields, particularly in biology, chemistry, and pharmacology. The first topological index was introduced by H. Wiener in 1947 [1]. Although its very first application was Read More

Recent Advances on Potentiometric Membrane Sensors for Pharmaceutical Analysis
Authors: Vinod K. Gupta, Arunima Nayak, Shilpi Agarwal and Barkha SinghalPrime concerns with modern developments are attributed to high level undetected but important biological substances or even toxicants cycled often among individual and populations; which in turn agonizes environmental monitoring, trace-gas detection, water treatment facilities, in vivo detection in biological fluids and other accomplishments. For the detection of such analytes, several analytical devices combined with bi Read More
