Latest Ranking of Biomedical Engineering programmes in U.S

U.S.News & World Report released its rankings for graduate engineering programs including a ranking of biomedical engineering and bioengineering. The rankings came out this month and are for those looking to enroll in programs in 2012.

U.S. News analyzed more than 1,200 graduate programs to create year’s rankings, according to the magazine. The U.S. News Grad Compass, Best Engineering Schools 2012

The rankings looked at tuition, total graduate engineering enrollment, research expenditures per faculty member, engineering school research expenditures, average GRE quantitative score (master’s and Ph.D. students) and more.

The rankings include:

#1  Johns Hopkins University (Whiting)
Baltimore, MD


Cutting the Spread of Tumors
Scientists have been looking at chlorotoxin, a peptide in scorpion venom, for the past decade as a way to target cancer cells. And the big payday has arrived. By combining nanoparticles with a scorpion venom mix already being investigated for treating brain cancer, University of Washington researchers found they could cut the spread of cancerous cells by 98 percent, compared to 45 percent for the scorpion venom alone (www.uwnews.org).
This is the first time that nanoparticles, which are ultrafine particles, have been combined with a treatment that physically stops cancer’s spread. “People talk about the treatment being more effective with nanoparticles but they don’t know how much, maybe 5 percent or 10 percent,” said Miqin Zhang, professor of materials science and engineering.  “This was quite a surprise to us.”  She is lead author of the study.
Chlorotoxin binds to a surface protein on many types of tumors, including brain cancer.  Chlorotoxin also disrupts the spread of tumors.
The Whole is Greater than the Parts
The researchers investigated chlorotoxin when it is attached to nanoparticles and found that the treatment’s effect doubles compared to chlorotoxin alone.  Adding nanoparticles often improves a therapy, partly because the combination lasts longer in the body and so has a better chance of reaching the tumor.  Combining also boosts the effect because therapeutic molecules clump around each nanoparticle.
Slowing the spread of cancer would be especially useful for treating highly invasive tumors, such as brain cancer.  The technique could hypothetically also slow the spread of other tumors with the same kind of activity, such as breast, colon, skin, lung, prostate, and ovarian cancers.
