Graphene derivative interferes with seemingly invincible cancer stem cells

By - February 25, 2015 2 Pictures
While well known for its unique electromechanical properties, graphene may also prove key in preventing cancer tumor recurrence. A drawback of traditional cancer treatment with radiation and chemotherapy is that the primary developmental source of future tumors is not eradicated. Cancer stem cells, or CSCs, can survive treatment and give rise to recurring tumors, metatasis, and drug resistance after repeated treatments. Researchers from the University of Manchester and the University of Calabria have discovered that graphene oxides targets and neutralize CSCs in a manner that is not yet fully understood. Read More

New study may provide fresh avenues of treatment for patients suffering from skin diseases

By - January 15, 2015 1 Picture
A fresh study carried out by researchers from King's College London (KCL) has established a link between a certain form of bacteria present on the skin following a surface wound and a type of white blood cell receptor, that together tip the scale away from the normal healing process and instead encourage the formation of cancerous tumors. The results of the study have the potential to create innovative treatment options for patients suffering from skin diseases, such as those that result in chronic ulcers and severe blistering.

Toxin-producing stem cells fight brain tumors where it matters most

By - October 27, 2014 1 Picture
When it comes to new tumor-fighting treatments, it’s often as much about location, location, location as it is the actual drug interaction. Cytoxin-producing stem cells produced by scientists at Harvard University lodge at the site of brain tumor removal to continually attack remaining tumor cells. As an alternative to drug treatments that can be invasive or ineffective, the researchers saw promising results against glioblastomas, which hold the dubious distinction of being the most common and most fatal brain cancer.

Two-in-one nanoparticles exploit tumor cells to precisely deliver multiple drugs

By - January 9, 2014 3 Pictures
A common strategy for treating tumors is combining two or more drugs, which has the effect of decreasing toxicity and increasing the synergistic effects between the drugs. However, the efficacy of this kind of cocktail treatment suffers when the drugs require access to different parts of the cell, a bit like fighting a battle by depositing all your archers on the same spot as your infantrymen. By making use of nanoparticle-based carriers, researchers at North Carolina State University are able to transport multiple drugs into cancerous cells optimally and precisely, in maneuvers that any field commander would be proud of.

New cancer radiation therapy treatment with no harmful side effects

By - April 3, 2013 1 Picture
Shortly after the discovery of the neutron in 1932, some scientists recognized the potential of boron neutron capture therapy (BNCT) as a cancer treatment. But despite decades of research, the problem of finding a delivery agent that would more effectively target the tumor without harming surrounding tissue persisted. Researchers at the University of Missouri (MU) may finally have found a solution. Read More

New device tests multiple chemotherapy drugs in a patient's living tumor

By - January 20, 2013 1 Picture
Seattle’s Presage Biosciences has developed a device which introduces small amounts of different chemotherapy drugs into a patient's tumor. The tumor is inspected after removal and the most effective of the drugs are used for post-surgical chemotherapy, resulting in more efficient, personalized cancer treatments. The new device is awaiting FDA approval, but is currently being used to facilitate development of new chemotherapy drugs. Read More

Breast implant with nanoscale "bed-of-nails" surface shown to deter cancer cells

By - March 24, 2012 4 Pictures
It's a sad reality of our time that breast cancer affects more women around the world than any other form of cancer. Even more disturbing is the fact that up to ten years after surgery, the cancer returns in nearly 20 percent of those deemed to have had successful tumor-removal operations. Now, researchers at Brown University (BU) in Providence, Rhode Island, led by engineering professor Thomas Webster, have developed an implant which they believe can appreciably lower that relapse rate by simultaneously inhibiting cancer cell growth and attracting healthy breast cells.

Scientists destroy tumors in mice using light therapy

By - November 13, 2011 1 Picture
Besides surgery, chemotherapy and radiation are the foundation of modern day cancer treatment. Although effective, these therapies often have debilitating and damaging side effects. But scientists at the National Cancer Institute in Bethesda, Maryland have been experimenting with a new form of therapy using infrared light to kill cancer cells and shrink tumors without damaging healthy tissue.

LED device could aid in cancer treatment

By - October 25, 2010 1 Picture
We’ve heard of surgeons using a SpectroPen during the tumor removal surgeries, but now Californian scientists are shedding light on cancer, literally, in the hopes to find a new cure for skin cancer. The team of scientists from the University of California, Irvine are currently developing new techniques to image cancerous lesions using LEDs (light emitting diodes) with the hope of then being able to treat skin cancer using photodynamic therapy (PDT).
