Eavesdropping on the body: New device tracks chemical signals within cells
Biomedical engineers at the University of Toronto have invented a new device that more quickly and accurately 'listens in' on the chemical messages that tell our cells how to multiply. The tool improves our understanding of how cancerous growth begins, and could identify new targets for cancer medications.

Eating in the absence of hunger: A recipe for expanding waistline
QUT researcher Dr Stephanie Fay has found that snacking when you're not hungry can cause weight gain as much as overly large portion sizes and energy-rich foods. Her findings have just been published in an international journal.

Targeting telomeres, the timekeepers of cells, could improve chemotherapy
In an unexpected finding, the Salk Institute and collaborators show how disabling telomere protection during cell division prompts cell death.

Tobacco Control
As smoking declines, more are likely to quit
Smokeless tobacco and, more recently, e-cigarettes have been promoted as a harm reduction strategy for smokers who are 'unable or unwilling to quit.' The strategy, embraced by both industry and some public health advocates, is based on the assumption that as smoking declines overall, only those who cannot quit will remain. A new study by researchers at UC San Francisco has found just the opposite.

DNA shed from head and neck tumors detected in blood and saliva
On the hunt for better cancer screening tests, Johns Hopkins scientists led a proof of principle study that successfully identified tumor DNA shed into the blood and saliva of 93 patients with head and neck cancer. A report on the findings is published in the June 24 issue of Science Translational Medicine.

Detroit patients' contributions to national study re-define low-grade brain tumor diagnosis
Sixty-seven patients from the Hermelin Brain Tumor Center at Henry Ford Hospital and their families made important contributions to a national cancer study that proposes a change in how some brain tumors are classified and ultimately treated. Published in the July 25 issue of the New England Journal of Medicine, the study reveals that a tumor's DNA is key to determining if a lower-grade malignant brain tumor may rapidly progress to glioblastoma.

Tiny particles in blood useful for early diagnosis of pancreatic cancer
A protein encoded by the gene glypican-1 present on cancer exosomes may be used as part of a potential non-invasive diagnostic and screening tool to detect early pancreatic cancer, potentially at a stage amenable to surgical treatment, according to a study at The University of Texas MD Anderson Cancer Center.

Current blood cancer drug prices not justified, MD Anderson study finds
The costs associated with cancer drug prices have risen dramatically over the past 15 years, which is of concern to many top oncologists. In a new analysis, researchers at The University of Texas MD Anderson Cancer Center concluded the majority of existing treatments for hematologic, or blood, cancers are currently priced too high to be considered cost-effective in the United States.

New colon cancer culprit found in gut microbiome
Changes in the gut bacteria of colon cancer patients indicate that some virulent bacteria could be linked to the progression of the disease, according to research published in the open-access journal Genome Medicine. The findings could eventually be used to identify a virulence signature in these cancers and help doctors predict how bacterial changes in patients' guts could affect their prognosis.

'Smarter' ordering of breast biomarker tests could save millions in health care dollars
A review of medical records for almost 200 patients with breast cancer suggests that more selective use of biomarker testing for such patients has the potential to save millions of dollars in health care spending without compromising care, according to Johns Hopkins researchers.

Viagra does something very important -- but it is unlikely to cause melanoma, researchers conclude
A rigorous analysis of more than 20,000 medical records concludes that erectile dysfunction drugs, such as Viagra, are not a cause of melanoma, an often deadly form of skin cancer, despite the higher risk for the disease among users of these drugs.

Nanometric sensor designed to detect herbicides can help diagnose multiple sclerosis
A nanobiosensor for the early diagnosis of certain types of cancer, as well as nervous system diseases such as multiple sclerosis and neuromyelitis optica, was developed by researches in São Paulo State, Brazil. The nanometric sensor is capable of identifying biomarkers of these pathological conditions. An article about the nanobiosensor has just been published as a cover feature by IEEE Sensors Journal.

Cardio-oncology services may improve patient care if more widely available
The impact of cancer treatments on cardiovascular health is an important consideration when treating cancer patients, but many hospital training programs have no formal training or services in cardio-oncology and a lack of national guidelines and funding are frequent barriers to establishing such programs, according to a nationwide survey published today in the Journal of the American College of Cardiology.

A fuse of cardiovascular diseases
A promising biomarker for the severity of age-related white matter changes and endothelial function was evaluated at Hiroshima University, Japan. The researchers at Hiroshima University investigated the association between the telomeric 3'-overhang length of leukocytes and vascular risk, ARWMCs, and endothelial function. They suggested that the telomere G-tail might be a useful marker of endothelial dysfunction, as well as stroke and dementia.

Award-winning agent developed for prostate cancer diagnosis and treatment
Scientists at the German Cancer Research Center have developed an agent called PSMA-617, which is capable of attaching specifically to prostate cancer cells. This agent can be labeled with various radioactive substances. When chemically bound to a weakly radioactive diagnostic radionuclide, it can detect prostate tumors and their metastases in PET scans. If labeled with a strongly radioactive therapeutic radionuclide, PSMA-617 can specifically destroy cancer cells. A first clinical application of this radiopharmaceutical at Heidelberg University Hospital has now delivered promising results.

Study could reduce unnecessary cancer screening

The results, published in the June 22nd edition of the New England Journal of Medicine, are expected to improve patient care and reduce screening costs around the world.
