The Shapes Of Life: NIGMS Project Yields More Than 1,000 Protein Structures

...stallization trials, and an imaging system quickly scans the wells looking for signs of crystal formation ?key to capturing protein structures. “At this large scale, it would be unthinkable to do all these steps by hand,?said John Norvell, Ph.D., director of the PSI at NIGMS and a scientist trained in pro...

Affymetrix and the Karolinska Institutet Announce Translational Medicine Strategic Alliance

...rolinska Institutet to perform high-density genome scans and genome-wide association studies on the genetics of complex diseases. About Affymetrix: Affymetrix scientists invented the world's first high-density microarray in 1989 and began selling the first commercial microarray in 1994. Since then, Affyme...

New Treatment Rivals Chemotherapy For Lymphoma, Study Finds

...dy processes the tagged antibody. Nuclear medicine scans are used to assess how quickly Bexxar reaches the tumor and how quickly the radiation disappears from the patient's body. One to two weeks after that initial dose, the patient then receives a custom-tailored therapeutic dose, and therapy is considere...

PET/MRI scans may help unravel mechanisms of prenatal drug damage

...e animals were anesthetized prior to scanning. MRI scans were performed first, followed by PET. For the PET study, each animal was injected with a trace quantity of cocaine--less than 10 micrograms, which is not enough to cause pharmacological effects. The injected cocaine had previously been "labeled," or...

Nanoparticles offer new hope for detection and treatment

...e glows brightly in MRI scans. In this study, MRI scans picked up tumors that were only a couple of millimeters (about one twenty-fifth of an inch) wide. Small, rapidly growing tumors cause growth of new blood vessels, which feed the tumors. To get the particles to bind to tumors, the researchers equippe...

PET/CT can identify new cancer lesions at early stage, allowing for prompt treatment

Next Generation Body Scanner Launched By The University Of Manchester

...scanning takes place and means that higher quality scans can be carried out at a much faster speed than ever before. The scanner will enable researchers to create images of structures in the body such as individual vessels in the brain, nerves and cartilage. Researchers working in the fields of cancer, st...

Brain Scan Study of Smokers Reveals Signature of Craving

"Like any multiple choice question, if you can learn something about one of the choices, it helps you with the other one,...

Methamphetamine Abuse, HIV Infection Cause Changes in Brain Structure

...University of California-San Diego conducted brain scans to analyze structural volume changes in 103 adults divided among four populations: methamphetamine abusers who were HIV-positive; methamphetamine abusers who were HIV-negative; nonabusers who were HIV-positive; and nonabusers who were HIV-negative.

New brain scan technology could save babies' lives

...ently, there are two main ways of performing brain scans on small babies. Magnetic resonance imaging (MRI) can provide data on brain function, but MRI scanners are large and static, and the baby may need to be sedated and wheeled to the scanner for the procedure to be carried out. The other alternative, ul...

Making medicine 'smarter'

...l of MRI technology, which cranks out at least 200 scans for a single patient, the sheer volume of images can be daunting for human eyes to evaluate. Meyer-Baese is developing computer software to mimic the way a radiologist analyzes all of that information -- and to do it better and faster. "The outco...

UCLA imaging study of children with autism finds broken mirror neuron system

...the children rehearsed the tasks prior to the fMRI scans to assure researchers they could perform the tasks. Both groups performed equally well. Normal brain activity in areas of the brain involving sight and facial movements indicated that the children with autism remained on task during the fMRI scans. ...
