Dynamics of Human Cells Revealed by Quantum Dots Adapted from the Best Practice entry from Laboratoire Kastler Brossel at the École Normale Supérieure and Université Pierre et Marie Curie
In living cells, the ability to selectively detect one molecule (or a small number of molecules) is a powerful way to understand the dynamics of cellular organization. This information is critical to understanding the fundamentals of cell biology and developing new drugs that effectively interact with human cellular targets.
Current imaging technology, however, is either too big or too inaccurate to enable researchers to observe single-molecule properties in living cells. The imaging probes of choice, organic fluorescent dyes, are toxic and kill cells on contact. They also remain visible for only a few seconds before photobleaching, or fading from sight. Thus, researchers using the dyes can catch only momentary glimpses of cells frozen in time. Yet a true understanding of single-molecule cellular processes can only be accomplished by observing them over extended periods of time.
Tracking Single-Molecule Cellular Interactions
Organization and Project: Laboratoire Kastler Brossel at the École Normale Supérieure's use of quantum dots to track glycine receptor dynamics for extended periods in living cells for the first time ever.
Vendors and Tools: Quantum dot imaging technology developed by Quantum Dot Corporation.
Key Benefits Realized: Observing the activity of glycine receptors in real time, researchers found that they were very active, moving to different parts of a synapse, to other synapses, and to areas outside the synapse. The breakthrough could lead to better drug design if researchers can determine how to increase the number of receptors at a given synapse.

Maxime Ben Dahan and his team of researchers at École Normale Supérieure, a top Paris research university, decided to test the ability of a new imaging technology called quantum dots (QDs) to observe single-molecule cellular interactions. Semiconductor quantum dots are nanoscale fluorescent probes that are extremely photostable, remaining visible for days or even weeks. Unlike fluorescent dyes, QDs do not harm living cells. Using QDs, Dahan and his team were able to track individual glycine receptors (GlyRs) in human cells for extended periods of time -- for the first time ever. The results are expected to help pharmaceutical companies develop new candidate drugs for the treatment of neurological disorders such as epilepsy and depression. Read More . . .
Cardinal Health Collects, Connects, and CollaboratesAdapted from the Cardinal Health's Best Practice entry
With an aggressive acquisition strategy and meteoric internal growth, Cardinal Health has increased sales from $5 billion to $50 billion in the past five years. Along with this phenomenal growth is the assimilation of businesses, facilities, capabilities, and cultures into one organization. The Pharmaceutical Technologies & Services group of Cardinal Health is a microcosm of this cataclysmic change and recognized the need to "act and feel" like one company to realize its value proposition of providing integrated, enabling technologies and services that bring quality products to market faster and deliver greater value for customers.
To help the organization achieve its "one company" objective, the e-Business & Knowledge Management department established the following goals:
Transparency - To make it easy for customers to take full advantage of Cardinal Health's services, including drug development, drug delivery, manufacturing, packaging, marketing, and logistics by providing a single electronic interface, whether the customer is working with one or many of Cardinal Health's business units.
Communication - To provide a common communications platform for disseminating information internally (Intranet) as well as externally (Extranet).
Collaboration - To make it easy for geographically dispersed individuals to quickly form teams and share information on projects.
Insight - To improve the decision-making process by giving employees access to important customer, competitor, and market intelligence information.
With these goals in mind, Cardinal Health created the Portal as the integration tool to enhance its efforts in each of these areas.
