Researchers create the first mouse model that develops a lymphoma the same way that humans do

This advancement has the potential to significantly speed the development of new, improved therapies for diffuse large B cell lymphoma (DLBCL), the most common type of human B cell lymphoma. Human B cell lymphomas cause 85 percent of non-Hodgkin's lymphomas, the sixth leading cause of cancer deaths in the United States.

Engineers have found a way to modify a plastic to anchor molecules that promote nerve regeneration, blood vessel growth or other biological processes

In the study led by Dr. Christine Schmidt, the researchers identified a piece of protein from among a billion candidates that could perform the unusual feat of attaching to polypyrrole, a synthetic polymer (plastic) that conducts electricity and has shown promise in biomedical applications.

SU11248 drug show promise against neuroendocrine tumors-stubborn cancers that respond poorly to chemotherapy

A unique, targeted anti-cancer drug appears to show promise against neuroendocrine tumors-stubborn cancers that have traditionally responded poorly to chemotherapy, according to research findings announced at the 2005 Annual Meeting of the American Society of Clinical Oncology (ASCO).

Patients with suspicious axillary lymph nodes in their breasts should first undergo ultrasound-guided fine-needle aspiration to avoid unnecessary surgery

Currently, breast cancer patients undergo axillary lymph node dissection for accurate staging and control of the cancer. In many cases, this major procedure can be replaced by sentinel lymph node biopsy, which is a more simple and less invasive surgical procedure, but many still have to undergo axillary dissection after the sentinel lymph node biopsy.

"Streaming detection" ultrasound could reduce number of diagnostic procedures for breast lumps

"Streaming detection" ultrasound accurately differentiated fluid-filled cysts from solid masses in a recent pilot study and has the potential to reduce the number of cyst aspirations and imaging follow-ups for breast masses that are indeterminate at conventional ultrasound, say researchers from Duke University Medical Center in Durham, NC.

Whole-body MRI takes less than twenty minutes to accurately scan a patient’s entire body for cancer spread to the bone

Whole-body MRI with an automatic moving table is effective for evaluating the entire skeleton in patients with suspected bone metastasis (cancer that has spread to the bone from other parts of the body) in a single imaging scan-and it only takes between 15 and 18 minutes, say two different European studies.

Digital mammography leads to significant decreases in the number of patients called back to the hospital for further mammograms

The use of digital mammography instead of conventional screen film mammography can lead to significant decreases in the number of patients called back to the hospital for further mammograms, making it easier on the patient and saving money, says a new study.

Expandable electrodes safe and effective for radiofrequency ablation of liver tumors

The use of expandable electrodes with multiple tips in the treatment of liver tumors by radiofrequency ablation (RFA) is safe and effective, making it a useful alternative to surgery in selected patients, say researchers from the University of Brescia in Italy.

Stents coated in polytetrafluoroethylene help keep blood vessels open for cirrhosis patients

Stents coated in polytetrafluoroethylene, the same substance used in non-stick cooking utensils, improves their ability to keep blood vessels open in TIPS procedures, decreasing occurrences of relapse and avoiding intervention, say a group of researchers led by Vina C. Williams, MD, from Leiden University Medical Center in the Netherlands.

Over-the-phone transmission of diagnostic-quality ultrasound images is possible

Over-the-phone transmission of diagnostic-quality ultrasound images is possible, potentially paving the way for ultrasound examinations to be performed in poorer areas of the world, inexpensively transmitted via the Internet, and read by experienced radiologists elsewhere, a new study shows.

MDCT overtakes ventilation-perfusion lung scan for diagnosing pulmonary embolism

MDCT pulmonary angiography is replacing the ventilation-perfusion lung scan to diagnose suspected pulmonary embolism in hospitalized patients, say researchers from Rhode Island Hospital in Providence.

Peer group pressure influences ethnic/racial prejudice in children

Children's tendency to show ethnic/racial prejudice is greater when their friends exclude individuals on the basis of race and when their peer groups felt threatened by outsiders, finds a new study published in the May/June issue of the journal Child Development.

Being a popular child has a downside

Although being popular is a primary goal for many teenagers--and their parents--a new study published in the May/June 2005 issue of the journal Child Development finds that popularity itself has a downside.

Multi-tasking skills develops late in adolescence

Parents of teenagers frustrated by their children's inability to focus on more than one thing at a time can take hope: a new study from researchers at the University of Minnesota in Minneapolis finds behavioral evidence that the part of the brain responsible for the ability to multi-task continues to develop until late adolescence.

Children of imprisoned mothers generally have insecure relationships with their mothers and caregivers

Children of imprisoned mothers generally have insecure relationships with their mothers and caregivers, according to a new study published in the May/June issue of the journal Child Development. However, the children were more likely to have secure relationships with their caregivers if they were living in a stable environment.
