Sharper MRI's

Magnetic resonance imaging, or MRI, has revolutionized health care, providing doctors with a highly accurate, non-invasive tool for diagnosing cancer, injuries and other maladies within the human body. Now, a Florida State University researcher has collaborated in a research project that could lead to ways of producing even sharper medical images.

Artificially engineered magnetic nanoparticles for ultra-sensitive molecular imaging

Iron oxide nanoparticles have shown promise as agents for detecting tumors using magnetic resonance imaging (MRI), but such efforts have been limited by the relatively weak magnetic signal generated by these nanoparticles.

Risk to childhood cancer survivors for late-occurring strokes

Children who are successfully treated for brain tumors or leukemia are more likely to have strokes later in life, according to new research from UT Southwestern Medical Center.

Modified silicon-based surfaces provide good home to proteins

Silicon, whether in its elemental form as silicon wafers or in its oxidized form, known as silicon dioxide or silica, is proving to be a valuable material for biomedical nanotechnology, in large part because of the biocompatibility and chemical inertness of these substances.

Distress, psychiatric syndromes, and impairment of function in women with newly diagnosed breast cancer

Almost half of newly diagnosed breast cancer patients are found to have clinically significant emotional distress or symptoms of psychiatric disorders before treatment is begun, according to a new study published in the December 15, 2006 issue of CANCER, a peer-reviewed journal of the American Cancer Society.

MRI technology breaks new ground in molecular imaging

Researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have developed a new technique for magnetic resonance imaging (MRI) that allows for detection of signals from molecules present at 10,000 times lower concentrations than conventional MRI techniques.

Novel attachment method provides boost to biosensor development

A versatile method for attaching precise amounts of biomolecules and even cells to electrically conductive surfaces could lead to a new generation of nanoscale biosensors with broad applicability in cancer diagnostics and basic research.

Mitochondrial DNA sequencing tool updated

High-tech laboratory tools, like computers, are often updated publicly as their analytical capabilities expand. In the September issue of the Journal of Molecular Diagnostics, NIH grantees report they have developed a second generation "lab on a silicon chip" called the MitoChip v2.0 that for the first time rapidly and reliably sequences all mitochondrial DNA.

Watch and wait the best option for low-risk prostate cancer

According to the American Cancer Society, 234,000 men will be diagnosed with prostate cancer this year, and 27,350 will die from it, but researchers say that as many as half of men diagnosed with low-risk prostate cancer undergo surgery or radiation therapy unnecessarily.

Little known about the impacts of cancer on the Australian workforce

Thirty seven thousand Australians aged 20-64 years of age were diagnosed with cancer in 2001 yet surprisingly little is known about the impacts of cancer on the Australian workforce.

Multiple cancer biomarkers detected simultaneously

Polymerase chain reaction (PCR) technology revolutionized diagnostic medicine and basic research through its ability to amplify and detect minute amounts of specific DNA sequences.

Rare abdominal cancer diagnosis being looked at in a different manner

Their experience treating a rare type of abdominal cancer has helped physicians at Wake Forest University Baptist Medical Center make a new discovery that may change the way it is diagnosed.

Significant differences in the patterns of mammography by race and ethnicity

Inadequate use of screening mammography may be an important reason that African-American women are more likely to be diagnosed with advanced stage breast cancer than members of other ethnic groups, according to a new study led by a University of California, San Francisco imaging specialist.

Alcohol use, tobacco use and male gender associated with an earlier onset of colorectal cancer

Colorectal cancer is the second leading cause of cancer deaths, according to background information in the article. Screening asymptomatic patients is an important strategy for reducing these deaths, because by the time patients experience symptoms, the cancer may have progressed beyond the point where it can be cured.

Custom made nanoparticles will transform cancer diagnosis and treatment

Researchers have developed "custom" nanoparticles that promise to provide a more targeted and effective way of delivering anticancer drugs than conventional medications or any of the earlier attempts to fight cancer with nanoparticles.
