PROBLEM: What is the sentiment of the following document towards the entity Imamu Baraka ? One good  Samaritan  Dr. Imamu Baraka   stepped in when  he  saw officials dumping the seemingly disoriented woman  who was still dressed in her hospital gown and socks  at a nearby bus stop.
 Baraka  says  he  was leaving  his  practice that evening when  he  saw what  he  calls "patient dumping" in action.
"At first I was shocked "  he  told The Associated Press. "I couldn't believe what I was seeing. And I move beyond that to the next level from being shocked. I became … irritated and fearful for the young lady. And then I became angry."
 He  quickly grabbed  his  cell phone to document the scene.
 Baraka   a psychotherapist in the area  says he hopes this unfortunate incident will open up a discussion of mental health in this country.

PROBLEM: What is the sentiment of the following document towards the entity Jenny Chang ? 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.

PROBLEM: What is the sentiment of the following document towards the entity Theresa May ? MANCHESTER  England (Reuters) - British Foreign Secretary Boris Johnson offered Theresa May unsolicited public advice about how to make Brexit a success on Tuesday  delicately testing the extent of the prime ministerâs weakened authority while pledging overt loyalty.
After praising May for winning a snap June election which lost  her  party its majority in parliament  Johnson used his main speech to say that  her  top ministers were united behind âevery syllableâ of  her  Brexit plans set out last month in Florence.
âThe whole country owes  her  a debt for  her  steadfastness in taking Britain forward  as  she  will  to a great Brexit deal  based on that Florence speech on whose every syllable  I can tell you  the whole cabinet is united â Johnson said.

Ahead of Johnsonâs speech   May  had repeatedly faced questions from reporters about whether  she  would sack Johnson after he appeared to undermine  her  Brexit strategy by setting out his own vision.  She  has sidestepped those questions.
