Ultra-detailed 3-D images of eyes reveal details of age-related macular degeneration

To get a better look at the abnormalities that cause age-related macular degeneration (AMD), the leading cause of vision loss in Americans and Europeans over 50, the research groups of James Fujimoto at the Massachusetts Institute of Technology (MIT) and collaborators Jay Duker of the Tufts University School of Medicine, and Joel Schuman of the University of Pittsburgh School of Medicine have created ultra-detailed 3-D images of the eyes of more than 2,000 people from different ethnic groups, 400 of whom have AMD.

Drug being used to improve cognition affects dopamine, suggesting potential for abuse

Preliminary research in healthy men suggests that the narcolepsy drug modafinil, increasingly being used to enhance cognitive abilities, affects the activity of dopamine in the brain in a way that may create the potential for abuse and dependence, according to a study in the March 18 issue of JAMA.

MRI and CT used to map intelligence in the brain

Neuroscientists at the California Institute of Technology (Caltech) have conducted the most comprehensive brain mapping to date of the cognitive abilities measured by the Wechsler Adult Intelligence Scale (WAIS), the most widely used intelligence test in the world.

Freezing kidney cancer - interventional cryoablation

Freezing kidney tumors - using a safe minimally invasive interventional radiology treatment that kills the cancer 100 percent effectively without surgery - should be the gold standard or first treatment option for all individuals with tumors that are 4 centimeters in size or smaller.

Radiolabeled nanoparticles boost PET-CT combination imaging

In an attempt to decrease the amount of cancer-targeting nanoparticle needed to image tumors, a team of investigators at the Massachusetts General Hospital and Harvard Medical School has developed a simple method for creating iron oxide nanoparticles labeled with 18F, a radioisotope that is easily detected using positron emission tomography (PET). The result is a nanoparticle that can be imaged using PET, computerized tomography (CT), and fluorescence imaging.

Peptide loaded gold nanospheres find, penetrate, then fuel burning of melanoma

Hollow gold nanospheres equipped with a targeting peptide find melanoma cells, penetrate them deeply, and then cook the tumor when bathed with near-infrared light, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reported in the Feb. 1 issue of Clinical Cancer Research.

PET/CT may improve prognosis for patients with inflammatory breast cancer

In the largest study to date to evaluate fluorodeoxyglucose positron emission tomography combined with computed tomography (FDG-PET/CT) in the initial staging of inflammatory breast cancer (IBC), researchers were able to identify the precise location and extent of metastasis (spread of disease), offering the potential for a better prognosis for patients with this rare, but aggressive form of breast cancer.
