Brain talk. Research fellow Babak Kateb, left, discusses the Impacts of thermal Imaging on brain tumors with neurosur geon John Peter Gruen Their study shows that the technology can be useful in surgeries
Better imaging targets tumors
Advancement has potential to help improve brain cancer patients 'prognosis
By KIM SIM
Sufl Writer
A USC neurological research team said it may liave found a more precise way to remove brain tumors by using thermal imaging.
babak Kateb, a neurosurgery research fellow, began a project last year to use an Infrared thermal imaging camera to identify the boundaries of a tumor.
The study, proposed by Kate!) and put into surgical practice by John Peter Gruen, LAC-USC Hospital medical staff association president elect, uses the difference in tempera ture between brain tumor tissue and
normal brain tissue to distinguish the two regions during a brain tumoi operation
Because tumor regions release more heat than normal tissue, a thermal imaging camera can detect the difference and translate it into a visual image using a coloi gradient What makes the complete removal of a brain tumor so difficult is that, to tiie naked eye, the tumor is not visibly distinguishable from noi mal brain tissue
"When you take out the tumoi from the brain, it doesn't look any different from the brain tissue itself, said Gruen, an associate professor ol neurosurgery “You may inadvertent ly take good stuff too, because you can't tell visually."
Unlike in other regions of the body, digging too deep into normal brain tissue poses tiie unique dangei I see Brain, page 10 I
Alabama politics seep onto campus
USC students react to the dramatic removal of a Ten Commandments icon
By PRATUL THAKER
Slaft Writer
Dramatic protests and prominent news coverage have thrown Alabama's judicial building and the removal of its two-ton monument of the Ten Commandments into the national spotlight, prompting political and religious discussion as far as USC.
Miles away from the heated Alabama discussions, ' Josh Cieszynski. a senior majoring in theater, said the removal of the two-ton monument of the Ten Commandments from the Alabama state Judicial Building’s rotunda was just another attempt to remove religion from public life.
“I think its a shame because (religion) is what the laws were founded on in this country,’ Cieszynski said.
At issue is a First Amendment clause in the Constitution which states "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof
Moore’s opponents, such as A.J. Nagaraj, a junior majoring in business administration and political science, have argued that the monument violates tne doctrine of separation of church and state.
“Placing the Ten Commandments in a courthouse definitely seems to me to be a blatant endorsement of one particular reli-I see NH0w, page f I
Trans fat slotted for new nutrition labels
High amounts of trans fat increase heart disease risk, many experts say By SHERRY ANNE RUBIANO
Staff Writer
Snack-food lovers beware: The cookies and crackers you munch on may be even less healthy than you think
Nutrition labels already list the amounts of saturated fat and total fat content in their food products.
but manufacturers must now list anothei type of fat In July, the U.S. Pood and Drug Administration issued a new regulation requiring unhealthy trans fatty acids, or trans fat, to be included on nutrition labels.
Foods that contain trans fat include cookies, snack foods, fried foods, crackers, candies baked goods, margarine, salad dressing, vegetable shortening and many processed foods, according to the FDA.
The FDA moved to make labels
more specific in an effort to help Americans make healthier diet decisions. Gating foods high in trans fat often raises blood cholesterol, according to the Dietary Guidelines for Americans 2000.
Other studies and imports show that high amounts of trans fat, saturated fat and cholesterol increase a persons risk of developing coronary heart disease, a leading cause of death in the United States. More than 500,000 die each year from causes related to heart disease, according to the FDA.
Patrice Barber, a nutritionist with Dining Services, said everyone should be concerned about the level of trans fat in their diet
“Thirteen million Americans have heart disease and the habits that you develop while you are young $re the ones that you will keep for your lifetime and will determine your risk.” Barber said.
Both trans fat and saturated fat raise low-density lipoprotein, LDL or "bad,” cholesterol, which is linked to a greater risk of coronary heart dis-

International
0/5 submitted thousands of foreign students data to U.S. government database

The lines at the Office of International Services have been shorter than expected this semester . because USC made the Aug 1 deadline to enroll international college students in a federal database.
USC, which has the largest international student population in the nation, sent its foreign students' data to a new Internet-based federal database maintained by the U.S. Department of Homeland Security's Bureau of Immigration and Customs Enforcement.
By meeting the deadline, most international students have been able to obtain visas and easily enroll in fall classes, Dixon C. Johnson, executive director of OIS, said.
"We put all the students into the ,r Student and Exchange Visitor Information System (SEVIS) —over 6,000 students," said Sumaiya S. Mamunm. an OIS. senior immigration officer.
SEVIS stores student information such as name, address and area of study. ICE uses it to track foreign** who enter the United States on student visas and-cut down on fraud.
Under dew rules, USC has to report to the government through SEVIS a student's failure to enroll 30 days after registration ends on Sept 12. And. if a student changes his name, address or academic program, USC has 21 days to report these events to the government
Each school that educates international students has to be certified by the Department of Homeland Security. Then, the school can issue students 1-20 forms to get visas.
