Verify if the sentiment of the following document towards the entity Jenny Chang is Neutral . A few years ago he began working with Dr. Jenny Chang  medical director of the Lester and Sue Smith Breast Center at Baylor College of Medicine.
 Chang had performed a number of biopsies on breast cancer patients  both on those whose cancers were confined to the breast and on those whose cancers had metastasized to the brain.
 From those biopsies  Chang said she had identified a number of genetic pathways ways in which gene mutations affected the ability of the cancer to spread unique to patients who developed metastatic breast cancer.
 "But I had a lot of trouble with the data and trying to translate it into clinical practice " she said. She couldn't find her way out from beneath the avalanche of data.
 So she turned to Wong.
 Using his mathematical modeling  Wong sifted through Chang's data and the large databases of genome and clinical trial data. Out of that  he identified several candidate drugs to impair the genetic pathways that helped the cancer spread.
Chang's data and the large databases of genome and clinical trial data. Out of that  he identified several candidate drugs to impair the genetic pathways that helped the cancer spread.
 One of them  a drug named sunitinib  which treats a kidney cancer called renal cell carcinoma  emerged as the best bet. Chang then tested the drug in mice  and the study showed it prevented breast cancer from spreading to the brain.
 She has already begun a Phase II clinical trial of the drug  enrolling nine patients with metastatic breast cancer  and she is looking for more.
 "The drug is very well-tolerated by patients  and so far the trial is going very well " Chang said.
 But by using an existing drug  Chang and Wong could skip the lengthy Phase I  during which a drug is checked for safety. If Chang's tests go well  sunitinib could be on the market within a few years for metastatic breast cancer.

Verify if the sentiment of the following document towards the entity George W Bush is Positive . After his reelection in 2004 , Bush sought major changes to Social Security , arguing a partial privatization plan could insure its solvency . 
The legacy of George W. Bush remains , much like his 2000 election , a subject of profound controversy , and any truly objective evaluation will likely be years in the future . 
The election of 2000 and the Supreme Court case of Bush v. Gore remain two of the most controversial political developments in the last half-century . 
Some thought that President Bush should begin his term by trying to find common ground and avoid controversy to take some of the edge off the nation 's polarized politics coming out of the 2000 election . 
Instead , as one of his first actions , President Bush issued an executive order creating the Office of Faith-Based and Community Initiatives , which further alienated some who thought government money should not go to organizations affiliated with churches . 
The Bush presidency transformed American politics , its economy , and its place in the world , but not in ways that could have been predicted when the governor of Texas declared his candidacy for America 's highest office . 
Within nine months of taking office , President Bush was afforded the chance to unite the nation after the terrorist attacks of September 11 , 2001 . 
By most accounts , Bush did a masterful job of speaking for and to the American people . 
As President , Bush became a lightning rod for controversy . 
Following an authorization from Congress to eliminate those who perpetrated the attacks of 911 , Bush ordered an invasion of Afghanistan . 
Those early successes , however , turned into the longest war in American history , and the President never was able to achieve the greatest symbolic goal of the effort , the killing or capturing of the mastermind of the attacks , Osama bin Laden ; U.S. special forces achieved that goal in 2011 under Bush 's successor , President Barack Obama . 
Following the 911 attacks , President Bush also presided over a restructuring of the American national security apparatus and the passage of the Patriot Act , which gave the government vast new powers in the effort to combat future acts of terror . 
Both efforts , especially the Patriot Act , sparked strong divisions within the American people throughout the Bush presidency . 
In 2002 and into 2003 , Bush used the fear of further terrorist attacks to argue for a preemptive war on Saddam Hussein 's Iraq under the rationale that Iraq had weapons of mass destruction . 
The last few months of the Bush presidency were marked by a major crash of the stock market , a controversial bail out of financial institutions and car companies , and a recession that would wipe out millions of jobs and impact the U.S. economy for many years . 
President Bush 's place in U.S. history will be debated and reconsidered for many years to come . 
On the domestic front , the Bush presidency scored early successes in gaining passage of large tax reductions and a major reform of the American educational system with the No Child Left Behind Act .
