Digital Mammography And Clinical Review Display Units Energising The European Markets For Medical Imaging Display Monitors, Finds Frost & Sullivan
Diagnostic display monitors have experienced slow growth in 2007 due to picture archiving and communication system (PACS) installations across radiology departments of European hospitals having reached saturation. However, favourable regulations mandating the sales of 5MP displays for digital mammography have ensured high-volume sales in several European countries. The increasing demand for clinical review display monitors from private practitioners has also ensured very high growth rates for medical imaging display monitors.

Economy Squeezing Access To Health Care
As unemployment rises, many Florida women are "turning to federally subsidized mammograms and pap smears, and county health officials are worried they could be overwhelmed," The Orlando Sentinel reports. "Since 1990, the Centers for Disease Control [and Prevention] has provided free and low-cost mammograms and pap smears to uninsured or underinsured women between 40 and 64 years old. In Florida, only women 50 to 64 years old qualify. Although the number of women screened in Florida through this federal program has increased through the years, unemployment in women 55 to 64 years old has nearly doubled, from 3.4 percent in 2008 to 6.3 percent now. Demand always has exceeded available services - only 15 percent of eligible women get the breast exams, according to the CDC - but the number of women who will now qualify for the free tests is expected to outstrip the funding provided by Congress" (Maza, 7/15).

More Support Needed For Families Adopting From Foster Care
A new University of Illinois study of families adopting from foster care revealed significant declines in professional services and social support over the first three years of adoptive family life, even though parents indicated that they need continued assistance.

Virus Filters For Medical Diagnosis

Providing reliable evidence of viruses in human blood presently requires time- and labor-intensive molecular-biological procedures. Established methods are particularly hard pushed to produce evidence when the viral burden is very low, for example during a phase of therapy. This could soon change. While developing new types of micro-pumps without movable parts, scientists from the Fraunhofer Institute for Biomedical Engineering IBMT came across an unexpected phenomenon: stable turbulence structures formed in the microscale pump channels. The nano- and microparticles actually intended to verify the pump effect accumulated in large quantities in the channels. The vortex patterns completely filled the whole microchannel, creating a virtually 100% trap for the particles that followed the generated flow profile, although there is a very large cross-section to flow through. "The development of flow vortices is nothing unusual on the macroscopic scale. However, in microchannels the flow lines almost run in parallel," explains Richard Stein from the IBMT. "The question, therefore, was, how is it possible for vortices to be formed from this which were sufficiently stable and effective for the concentration of nanoparticles?" Experiments were not successful in determining the parameters by which the filter effect could be systematically controlled. This is because in the pump mechanism examined, high-frequency electrical traveling waves propel the fluid into the microchannels, superimposing a large number of effects on one another. "In order to understand the complex procedures, there was a clear need for a theoretical description. My task was to describe the surprising phenomenon and to make it controllable," reflects Richard Stein. In his thesis "Mathematical modeling, analysis and numerical simulation of electrothermally driven micropumps", Richard Stein succeeded in explaining the development of the vortex pattern. To this end, he had to factor in all the relevant processes - of an electrical, thermal and hydrodynamic nature - in a three-dimensional model. Mr. Stein will receive the 1st Hugo Geiger Prize for this paper. The findings contained in the paper explain the observed effects completely, so that now both effective micropumps and efficient particle filters can be developed and built for many biomedical applications.
