Digital Imaging Ready for Prime Time

Ready for Prime Time

Opening of the voltage-dependent Ca 2 channels permits influx of Ca across the plasma membrane, triggering diverse physiological processes. These channels are widely distributed in the cardiovascular system, constituting the main route for Ca entry essential for excitation and contraction. Ten unique 1 subunits, grouped in 3 families (CaV1, CaV2, and CaV3), that encode the low-voltage– activate...

Imaging for coronary risk assessment: ready for prime time?

Imaging cell biology in live animals: Ready for prime time

Time-lapse fluorescence microscopy is one of the main tools used to image subcellular structures in living cells. Yet for decades it has been applied primarily to in vitro model systems. Thanks to the most recent advancements in intravital microscopy, this approach has finally been extended to live rodents. This represents a major breakthrough that will provide unprecedented new opportunities t...

Ready for prime time? Dual tracer PET and SPECT imaging.

Dual isotope single photon emission computed tomography (SPECT) and dual tracer positron emission tomography (PET) imaging have great potential in clinical and molecular applications in the pediatric as well as the adult populations in many areas of brain, cardiac, and oncologic imaging as it allows the exploration of different physiological and molecular functions (e.g., perfusion, neurotransm...

Ready for the Prime Time?

Metabolomics is one of the most rapidly growing areas of contemporary science. Although classic genetics aims to link variations in the DNA sequence directly to distinct phenotypes, “-omic” technologies allow us to shift the focus from the specific gene to the actual effects of the gene itself. Because neither the transcriptional or protein profile can be directly correlated with metabolite con...
