Novel angled gantry approach reduces breast radiation exposure

A novel angled gantry approach to coronary CT angiography reduced radiation exposure to the breast by more than 50%, according to Thomas Jefferson University researchers.

Cancer stem-cell model tested by University of Michigan researchers

One of the most promising new ideas about the causes of cancer, known as the cancer stem-cell model, must be reassessed because it is based largely on evidence from a laboratory test that is surprisingly flawed when applied to some cancers, University of Michigan researchers have concluded.

Scientists show that endothelial cells give rise to blood stem cells

Stem cell researchers at UCLA have proven definitively that blood stem cells are made during mid-gestational embryonic development by endothelial cells, the cells that line the inside of blood vessels.

Low-dose peginterferon used for hepatitis C doesn't work

An NIH funded multi-center clinical trial found no benefit from "maintenance therapy," low-dose peginterferon used for hepatitis C patients who have not responded to an initial round of treatment.

Light exposure therapy, dark sunglasses help night-shift workers

A new study finds the use of light exposure therapy, dark sunglasses and a strict sleep schedule can help night-shift workers create a "compromise circadian phase position," which may result in increased performance and alertness during night shifts while still allowing adequate nighttime sleep on days off.

Natural killer T cells play important role in Lyme disease

A research team led by the La Jolla Institute for Allergy & Immunology and Albany Medical College has illuminated the important role of natural killer (NK) T cells in Lyme disease, demonstrating that the once little understood white blood cells are central to clearing the bacterial infection and reducing the intensity and duration of arthritis associated with Lyme disease.

Discovery of new enzyme in cancer growth

While studying the mechanics of blood clots, researchers at the University of Oklahoma Health Sciences Center discovered a new enzyme that not only affects the blood, but seems to play a primary role in how cancer tumors expand and spread throughout the body.

Degarelix prostate cancer drug makes testosterone levels fall dramatically and quickly

More than 95 per cent of men who took degarelix for prostate cancer saw their testosterone levels fall dramatically as early as three days after they started treatment, according to a paper in the December issue of BJU International.

Anti-oestrogen drugs may promote more harmful cancer cell behaviour

The authors found that tamoxifen can promote an invasive phenotype in ER+ breast cancer cells under conditions of poor cell-cell contact, a previously unknown effect of this drug

Breast-specific gamma imaging identifies hidden breast cancer

Breast-Specific Gamma Imaging (BSGI) is shown to be an effective method of identifying mammographically and clinically occult (hidden) breast cancer.

New standard of care for treating advanced ovarian cancer

Results of a phase III, international randomized clinical trial demonstrate a new standard of care for treating advanced ovarian cancer that significantly reduces side-effects and post-operative deaths compared to the previously established treatment course.

Genetic breakdown in Fanconi anemia may have link to HPV-associated cancer

A genetic malfunction that causes DNA instability in people with the blood disorder Fanconi anemia may put them at high risk for squamous cell carcinomas linked to human papillomavirus (HPV), according to a study posted online ahead of print by Oncogene.

New insights into cellular senescence

Scientists have identified a molecular cause behind the ravages of old age and in doing so have also shown how a natural process for fighting cancer in younger persons can actually promote cancer in older individuals.

Broccoli compound, indole-3-carbinol targets key enzyme in late-stage cancer

An anti-cancer compound found in broccoli and cabbage works by lowering the activity of an enzyme associated with rapidly advancing breast cancer, according to a University of California, Berkeley, study appearing this week in the online early edition of the journal Proceedings of the National Academy of Sciences.

Men who survive childhood leukemia have lower bone mineral density

Men who survived childhood leukemia treatment into adulthood were more likely to have low bone mineral density than other adults their age, putting them at risk of osteoporosis and bone fractures, according to a new study.

Alpha-catenin protein provokes healthy cell bonding

In human relationships, a certain "spark" often governs whether we prefer one person more than another, and critical first impressions can occur within seconds. A team lead by Johns Hopkins researchers has found that cell-to-cell "friendships" operate in much the same way and that dysfunctional bonding is linked to the spread of cancer.

Prototype blood scanner detects even faint indicators of cancer

A team led by Stanford researchers has developed a prototype blood scanner that can find cancer markers in the bloodstream in early stages of the disease, potentially allowing for earlier treatment and dramatically improved chances of survival.

Reactions to HPV vaccine Gardasil rare

Research by Australian scientists has found that adverse reactions to the HPV vaccine Gardasil are rare and most schoolgirls are able to tolerate subsequent doses.

New technique provides closer look at DNA and mRNA

In a study in the advance online edition of Nature Structural and Molecular Biology, researchers from Albert Einstein College of Medicine describe a technique for looking more precisely at a fundamental step of a cell's life - a gene, DNA, being read into a message, mRNA.

Cancer risk from cardiac computed tomography overstated

Radiology and cardiovascular researchers from the Medical University of South Carolina in Charleston, S.C., today present new data that shows the risk of cancer from exposure to radiation during computed tomography for cardiovascular disease has been overstated and that new estimates are several times lower than previously published conclusions.
