Researchers develop oral delivery system to treat inflammatory bowel diseases
October 9, 2010 by admin · Leave a Comment
Researchers at the Georgia Institute of Technology and Emory University have developed a novel approach for delivering small bits of genetic material into the body to improve the treatment of inflammatory bowel diseases. Delivering short strands of RNA into cells has become a popular research area because of its potential therapeutic applications, but how to deliver them into targeted cells in a living organism has been an obstacle.

Researchers clear hurdle on path toward gene-therapy treatment for disease
One of the most difficult aspects of working at the nanoscale is actually seeing the object being worked on. Biological structures like viruses, which are smaller than the wavelength of light, are invisible to standard optical microscopes and difficult to capture in their native form with other imaging techniques.
A cluster bomb for cancer care
Tel Aviv University develops nano-vehicle to deliver chemotherapy treatments on target
Chemotherapy, while an effective cancer treatment, also brings debilitating side effects such as nausea, liver toxicity and a battered immune system.

New nanomaterial could improve therapeutics and imaging in cancer treatment
Scientists from UCLA’s California NanoSystems Institute and Korea’s Yonsei University have developed an innovative method that enables nanomachines to release drugs inside living cancer cells when activated remotely by an oscillating magnetic field.
A ‘magnetic’ solution to identify and kill tumors
Tel Aviv University researcher develops nano-methods for treating cancer tumors with heat and magnets
Though a valuable weapon against cancerous tumors, radiation therapy often harms healthy tissue as it tries to kill malignant cells. Now, Prof. Israel Gannot of Tel Aviv University’s Department of Biomedical Engineering is developing a new way to destroy tumors with fewer side effects and minimal damage to surrounding tissue.
Novel bee venom derivative forms a nanoparticle ’smart bomb’ to target cancer cells

New research in the FASEB Journal shows that a peptide derived from bee venom can deliver liposomes bearing drugs or diagnostic dyes to specific cells or tissues
The next time you are stung by a bee, here’s some consolation: a toxic protein in bee venom, when altered, significantly improves the effectiveness liposome-encapsulated drugs or dyes, such as those already used to treat or diagnose cancer. This research, described in the August 2010 print issue of the FASEB Journal (http://www.fasebj.org), shows how modified melittin may revolutionize treatments for cancer and perhaps other conditions, such as arthritis, cardiovascular disease, and serious infections.

New technology targets cancer prevalent in young women
CHICAGO — You can teach an old drug new chemotherapy tricks. Northwestern University researchers took a drug therapy proven for blood cancers but ineffective against solid tumors, packaged it with nanotechnology and got it to combat an aggressive type of breast cancer prevalent in young women, particularly young African-American women.

TORONTO, ON A team of scientists led by Eugenia Kumacheva of the Department of Chemistry at the University of Toronto has discovered a way to predict the organization of nanoparticles in larger forms by treating them much the same as ensembles of molecules formed from standard chemical reactions.
Evidence that nanoparticles in sunscreens could be toxic if accidentally eaten
June 22, 2010 by admin · Leave a Comment
Scientists are reporting that particle size affects the toxicity of zinc oxide, a material widely used in sunscreens. Particles smaller than 100 nanometers are slightly more toxic to colon cells than conventional zinc oxide. Solid zinc oxide was more toxic than equivalent amounts of soluble zinc, and direct particle to cell contact was required to cause cell death. Their study is in ACS’ Chemical Research in Toxicology, a monthly journal.
