MRI improves breast cancer diagnosis

Women who have been diagnosed with breast cancer in one breast have a higher risk of contracting the disease in their opposite breast as well. A thorough examination of the opposite breast using mammography and ultrasound is therefore common practice. However, many tumours still remain undetected when using mammography.

Women under 65 with cancer most likely to suffer emotional distress

Women under 65 are the most likely of all cancer patients to suffer from significant emotional distress - a study reports today in the British Journal of Cancer.

Obesity at the time of prostate-cancer diagnosis dramatically increases the risk of dying from the disease

Obese men who are diagnosed with prostate cancer have more than two-and-a-half times the risk of dying from the disease as compared to men of normal weight at the time of diagnosis, according to a study by researchers at Fred Hutchinson Cancer Research Center.

Effect of depression in mothers with breast cancer on their children's concerns

A woman's breast cancer diagnosis can wreak as much havoc on her emotions as it does on her physical health. Mothers who experience bouts of depression during their battles with breast cancer may find that the effects reach beyond their own psyches to those of their children.

Why are African American women more likely than White women to die from breast cancer?

Why are African American women 1.5 to 2.2 times more likely than White women to die from breast cancer, despite their lower incidence of the disease? Is it solely because they have less access to medical care? Maybe not, according to a new analysis that will appear in an upcoming issue of the International Journal of Surgery.

A black and white look at breast cancer mortality

African and African American women are more likely to die of breast cancer than their white counterparts because they tend to get the disease before the menopause, suggests new research from the University of East Anglia and the Children’s Hospital Boston in collaboration with researchers in the U.S. and Italy.

Clarient receives patent for "automated detection of objects in a biological sample"

Clarient, Inc. has announced that it has been granted a new U.S. patent related to the detection and quantification of rare tumor cells in blood and bone marrow.

Nanoparticles rely on 'velcro effect' to target tumor cells

One of the basic tenets of targeted nanoparticle drug delivery is putting multiple targeting molecules on a nanoparticle surface will improve the ability of nanoparticles to stick to their targeted cell and deliver their drug cargos to the appropriate diseased cell.

Nano printing technique produces model membranes

An international team of investigators based in the United States and Germany has modified the nanoscale printing technique known as dip-pen nanolithography to create large numbers of model cell membranes.

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.

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.
