Sense in Pb2+ sensing.
It is generally acknowledged that Pb(2+), which is sequestered by live cells from their direct environment, affects a large number of cellular processes at picomolar to micromolar concentrations. However, resolving the specific molecular targets and mechanisms responsible for the neurotoxic effects of this xenobiotic metal is hampered by the lack of suitable tools to investigate the intracellul...
متن کاملCation identity dependence of crown ether photonic crystal Pb2+ sensing.
We quantitatively modeled the volume phase transition of a hydrogel containing a crystalline colloidal array with a crown ether ligand which binds Pb2+. The hydrogel volume response and the wavelength diffracted depend on the Pb2+ concentration and on both the ionic strength and the valence of the nonbinding ionic species. We successfully modeled the response of this hydrogel Pb2+ sensor to ion...
متن کاملQuorum Sensing: Bacteria Talk Sense
Cell communication in bacteria occurs through a vernacular of small diffusible chemical signals that impact gene regulation during times of high cell density. This form of intercellular signaling, known as quorum sensing, optimizes the metabolic and behavioral activities of a community of bacteria for life in close quarters. Quorum sensing is best characterized as a means of communication withi...
متن کاملAccelerating SENSE using compressed sensing.
Both parallel MRI and compressed sensing (CS) are emerging techniques to accelerate conventional MRI by reducing the number of acquired data. The combination of parallel MRI and CS for further acceleration is of great interest. In this paper, we propose a novel method to combine sensitivity encoding (SENSE), one of the standard methods for parallel MRI, and compressed sensing for rapid MR imagi...
متن کاملAccelerating SENSE using distributed compressed sensing
INTRODUCTION: With the emergence of compressed sensing (CS) theory (1-2), its combination with parallel magnetic resonance imaging (pMRI) is of great interests. SparseSENSE has been proposed independently (3-6) which applies CS to SENSE (7) with random sampling as a regularization method. However, there are a couple of issues with the method. First, the incoherence condition required in CS cann...
