Malaria could be tested early by cheap, portable device
8/19/2013
A device that measures electrical properties of red blood cells is able to detect if they are infected with malaria in the early stages. The researchers hope their findings will lead to a portable and low-cost, yet highly sensitive device that can diagnose malaria on the spot using just a drop of blood...
Protein biomarkers identified that predict time to ovarian cancer recurrence
8/19/2013
Ovarian cancer often remains undetected until it is at an advanced stage. Despite positive responses to initial treatment, many patients are at risk of tumor recurrence. A multitude of genetic markers have been implicated in ovarian cancer prognosis. However, the genetic testing required is not practical or affordable in a clinical setting...
Scientists find and assess prostate tumors with the help of sugar
8/19/2013
A natural form of sugar could offer a new, noninvasive way to precisely image tumors and potentially see whether cancer medication is effective, by means of a new imaging technology developed at UC San Francisco in collaboration with GE Healthcare. The technology uses a compound called pyruvate, which is created when glucose breaks down in the body and which normally supplies energy to cells...
2 miRNAs found to correlate with survival in urinary bladder cancer
8/19/2013
German researchers have identified four biomarkers that correctly determine malignancy of urinary bladder cancers and contribute to the accurate prediction of patient outcomes. Their results are published in the September issue of The Journal of Molecular Diagnostics...
As many as 1 in 5 women don't believe their breast cancer risk
8/19/2013
Despite taking a tailored risk assessment tool that factors in family history and personal habits, nearly 20 percent of women did not believe their breast cancer risk, according to a new study from the University of Michigan Comprehensive Cancer Center...

Insights into the mechanisms underlying angiogenesis in lung metastases
8/19/2013
Cancer metastasis requires tumor cells to acquire properties that allow them to escape from the primary tumor site, travel to a distant place in the body, and form secondary tumors. But first, an advance team of molecules produced by the primary tumor sets off a series of events that create a network of nurturing blood vessels for arriving primary tumor cells to set up shop...
Attacking the architecture of the cancer cell may help children with hard-to-treat neuroblastoma
8/19/2013
Children with a particularly lethal cancer could benefit from potentially life-saving treatment, following breakthrough work led by researchers at the University of New South Wales (UNSW). A whole new class of drugs has been developed that, for the first time, targets the structure of the cancer cell...
Fighting cancer with nanoparticles
8/17/2013
Researchers at the University of Georgia are developing a new treatment technique that uses nanoparticles to reprogram immune cells so they are able to recognize and attack cancer. The findings were published recently in the early online edition of ACS Nano. The human body operates under a constant state of martial law...
Study of melittin-based pore formation has implications for fighting cancer and bacteria
8/17/2013
A new study by Rice University biophysicists offers the most comprehensive picture yet of the molecular-level action of melittin, the principal toxin in bee venom. The research could aid in the development of new drugs that use a similar mechanism as melittin's to attack cancer and bacteria. The study appears in the Proceedings of the National Academy of Sciences...
