Broad spectrum sunscreens needed to block UVB and UVA

Writing in the latest edition of Australian Prescriber, Associate Professor Jane Hanrahan from the Faculty of Pharmacy, University of Sydney writes that UVB is the cause of sunburn, but UVA can be more damaging to the skin. It is therefore best to use broad spectrum sunscreens that block both wavebands.

New nanotechnology detects micrometastases in mouse models of breast cancer

Malignant cells that leave a primary tumor, travel the bloodstream and grow out of control in new locations cause the vast majority of cancer deaths. New nanotechnology developed at Case Western Reserve University detects these metastases in mouse models of breast cancer far earlier than current methods, a step toward earlier, life-saving diagnosis and treatment.

Researchers to probe causes, treatments of toxic reactions in blood plasma

In the largest undertaking of its kind, scientists at four leading U.S. research institutions are embarking upon a five-year National Institutes of Health (NIH)-funded study to make blood transfusions safer and more effective by uncovering the exact causes of hemoglobin toxicity.

Nanoparticles for non-invasive photodynamic therapy of deep cancer

National University of Singapore researchers at the Faculty of Engineering's Department of Bioengineering have discovered a new technology that paves the way for a new safe and non-invasive method of treating deep cancer. Led by Associate Professor Zhang Yong, the team has so far, proven that their technology could inhibit tumour growth and control gene expression in mice. This is a world's first for the use of nanoparticles for non-invasive photodynamic therapy of deep cancer.

UMass Amherst develops 'chemical nose' array to detect metastatic cancers

In the fight against cancer, knowing the enemy's exact identity is crucial for diagnosis and treatment, especially in metastatic cancers, those that spread between organs and tissues. Now chemists led by Vincent Rotello at the University of Massachusetts Amherst have developed a rapid, sensitive way to detect microscopic levels of many different metastatic cell types in living tissue. Findings appear in the current issue of the journal ACS Nano.

Scientists describe how DNA origami can enhance effect of cytostatics in cancer treatment

Scientists at Karolinska Institutet in Sweden describe in a new study how so-called DNA origami can enhance the effect of certain cytostatics used in the treatment of cancer. With the aid of modern nanotechnology, scientists can target drugs direct to the tumour while leaving surrounding healthy tissue untouched.

RNA-delivering nanoparticles allow rapid screening of new drug targets in mice

By sequencing cancer-cell genomes, scientists have discovered vast numbers of genes that are mutated, deleted or copied in cancer cells. This treasure trove is a boon for researchers seeking new drug targets, but it is nearly impossible to test them all in a timely fashion.
