The overall aim of this study is to determine the most effective way to reduce the radiation dose to the breast during non-breast related CT scans, whilst still maintaining a suitable image quality. This study will attempt to compare the doses and noise of various protocols that can be used for dose reduction, including tube current modulation, bismuth breast shields and manual reduction of tube current.

Fluorescence ratio imaging indicates that immobilized, aspirin-treated platelets, loaded with Fura-2, respond to inositol 1,4,5-trisphosphate- (InsP3)-generating agonists such as thrombin by high-frequency, irregular rises in cytosolic [Ca 2+ ] i with spikes that vary in peak level and peak-to-peak interval. This differs from the regular [Ca 2+ ] i oscillations observed inother, larger cells.

When studiedin vitro, mitochondrial permeability transition (MPT) is associated with an increase in mitochondrial per-meability to solutes up to 1500 Da in mass and a loss of electrical potential difference across the inner mitochondrial membrane (Dwmit). The MPT has been implicated as being important in cellular calcium homeostasis, autophagy and cell death via necrosis and apoptosis.

The function of microRNAs (miRNAs) is translational repression or mRNA cleavage of target genes by binding to 3¢-UTRs of target mRNA. In this study, we investigated the functions and the target genes of micro-RNA124a (miR124a), and imaged the miR124a-mediated repression of chromosome 14 open reading frame24(c14orf24, unknown function) during neurogenesis, using noninvasive luciferase systems.

There is growing concern about the safety of engineered nanoparticles, which are produced for various industrial applications. Quantum dots are colloidal semiconductor nanoparticles that have unique luminescence char-acteristics and the potential to become attractive tools for medical imaging. However, some of these particles can cause oxidative stress and induce cell death.

Digital signal processing has revolutionized the storage and transmission of audio and video signals as well as still images, in consumer electronics and in more scientific settings (such as medical imaging). The main advantage of digital signal processing is its robustness: although all the operations have to be implemented with, of necessity, not quite ideal hardware, the a priori knowledge that all correct outcomes must lie in a very restricted set of well-separated numbers makes it possible to recover them by rounding off appropriately. ...
