Researchers study Rituximab's action on cancer stem cells

Preliminary data from one of the first clinical trials to test a stem cell-targeting drug in cancer patients shows that while the drug did not prolong survival, its suppressing effect on patients' stem cells was impressive enough to send investigators looking for a better drug to try.

Removal of superficial tumors in esophagus by endoscopy can avoid extirpation of this part

The removal through endoscopy of tumours that affect only the superficial layers of the oesophagus can avoid complete extirpation of this part of the digestive tract.

Methamphetamine addiction mechanism discovered

Researchers have identified, for the first time, long-term changes in the brain circuitry of methamphetamine-addicted mice that can explain why the craving of addiction is so stubborn and long-lived.

Synthetic molecules may be less expensive alternative to therapeutic antibodies

Researchers at UT Southwestern Medical Center have developed a simple and inexpensive method to screen small synthetic molecules and pull out a handful that might treat cancer and other diseases less expensively than current methods.

New test for cervical cancer

The Pap test has been the standard screening tool for cervical cancer for years -- and it still is.

3 Apr 2008

New type of imaging system illuminates tumors to nearly one-trillionth of a meter

Doctors' quest to see what is happening inside a living body has been hampered by the limits on detecting tiny components of internal structures and events.

Astrotechnology brings nanoparticle probes into sharper focus

While pondering the challenges of distinguishing one nanosize probe image from another in a mass of hundreds or thousands of nanoprobes, two investigators at Emory University and the Georgia Institute of Technology made an interesting observation. The tiny, clustered dots of light looked a lot like a starry sky on a clear night.

Next-generation nanomedicine

In an article featured on the cover of the March issue of Nature Nanotechnology, Mauro Ferrari, Ph.D., of The University of Texas Health Science Center at Houston, presented a proof-of-concept study on a new multistage delivery system (MDS) for imaging and therapeutic applications. This discovery could go a long way toward making injectable drugs more effective.

A biosensing nanodevice to revolutionize health screenings

One day soon a biosensing nanodevice developed by Arizona State University researcher Wayne Frasch may eliminate long lines at airport security checkpoints and revolutionize health screenings for diseases like anthrax, cancer and antibiotic resistant Staphylococcus aureus (MRSA).

26 Mar 2008

MRI opens up promising new avenues for non-invasive diagnoses and classification of cancer

Doctors diagnose and prescribe treatment for brain tumors by studying, under a microscope, tumor tissue and cell samples obtained through invasive biopsy or surgery.
