Holographic images use shimmer to show cellular response to anticancer drug
03-06-2007 · EurekAlert!The response of tumors to anticancer drugs has been observed in real-time 3-D images using technology developed at Purdue University. The new digital holographic imaging system uses a laser and the same microchip used in household digital cameras, to see inside tumor cells. The device also may have applications in drug development and medical imaging.

- Penn researchers show how nanocylinders deliver medicine better than nanospheres
04-05-2007 · EurekAlert!
Researchers at the University of Pennsylvania School of Medicine have discovered a better way to deliver drugs to tumors. By using a cylindrical-shaped carrier they were able sustain delivery of the anticancer drug paclitaxel to an animal model of lung cancer ten times longer than that delivered on spherical-shaped carriers. These findings have implications for drug delivery as well as for better understanding cylinder-shaped viruses like Ebola and H5N1 influenza.

- ADHD Appears to Be Associated With Depressed Dopamine Activity in the Brain
08-06-2007 · Brookhaven National Laboratory
Adults with attention-deficit/hyperactivity disorder (ADHD) show a blunted response to the drug methylphenidate (Ritalin), which increases brain dopamine levels. This suggests that dopamine dysfunction may be involved with ADHD symptoms and may contribute to substance abuse that often occurs simultaneously.

- Growth factor receptor affects prostate cancer progression
12-10-2007 · EurekAlert!
Breeding mice with a gene for a cellular receptor that can be turned on and off-at will-not only enabled researchers at Baylor College of Medicine in Houston to show how prostate cancer progresses, but also provides a model for studying when a drug targeting a gene will have an effect on the cancer.

- Prototype for long wavelength array sees first light
03-29-2007 · EurekAlert!
Astronomers at the Naval Research Laboratory (NRL) have produced the first images of the sky from a prototype of the Long Wavelength Array (LWA), a revolutionary new radio telescope to be constructed in southwestern New Mexico. The images show emissions from the center of our galaxy, a supermassive black hole, and the remnant of a star that exploded in a supernova over 300 years ago.

- Tracing broken wiring in stroke patients
03-14-2007 · EurekAlert!
Researchers have used a technique to trace the functional disruption in brain circuitry that causes stroke patients to show a lack of awareness or response to the side of the body opposite to the side of the stroke lesion in the brain. The researchers said their findings shed new light on the neurological details of this "spatial neglect."
