TL;DR: The proposed method to learn an over-complete dictionary is based on extending the K-SVD algorithm by incorporating the classification error into the objective function, thus allowing the performance of a linear classifier and the representational power of the dictionary being considered at the same time by the same optimization procedure.

TL;DR: It is shown that miR-1 is overexpression in individuals with coronary artery disease, and that when overexpressed in normal or infarcted rat hearts, it exacerbates arrhythmogenesis and is a potential antiarrhythmic target.

TL;DR: Positively-charged gold nanoparticles possess intrinsic peroxidase-like activity, and can catalyze oxidation of the per oxidase substrate 3,3,5,5-tetramethylbenzidine by H(2)O( 2) to develop a blue color in aqueous solution, thus providing a simple approach to colorimetric detection of H(1)O (2) and glucose.

TL;DR: The assay shows excellent selectivity for Hg2+ over other metal cations including K+, Ba2+, Ni2+, Pb2+, Cu2+, Cd2+, Mg2+, Ca2+, Zn2+, Al3+, and Fe3+.

TL;DR: In this article, a simple and rapid colorimetric detection method for melamine in raw milk using gold nanoparticles as probe is presented. But the method is rather simple, and the whole process including sample pretreatment takes only 12min at room temperature.
