Q: NEW YORK (AP) -- Pfizer Inc. said Friday it is pulling its blood pressure drug Thelin off the market and stopping all clinical trials because the drug can cause fatal liver damage.
 Thelin is sold in the European Union  Canada  and Australia as an oral treatment for severe pulmonary arterial hypertension  or high blood pressure in the pulmonary artery. Pfizer said a review of data from clinical trials and post-marketing reports showed a new link to liver injury. It also consulted with experts about the link between Thelin and the deaths of two patients.
 Liver damage was a known side effect of Thelin and similar drugs  the company said. Pfizer said the withdrawal was voluntary and added that it has withdrawn its filing for marketing approval in the U.S.
 Since there are other treatment options  Pfizer said the benefits of Thelin don't outweigh the risks. It is stopping all studies of the oral drug  which Pfizer acquired in 2008 when it bought Encysive Pharmaceuticals Inc. Encysive had been trying to win marketing approval for Thelin since 2005  but the Food and Drug Administration said it was not effective enough. Other agencies only approved the drug for hypertension that was so debilitating that patients' physical activity was severely limited.
 The chemical name of Thelin is sitaxsentan.

Q: During the war  no one was more emblematic of the changing power dynamics than  Farah Baker   a 16-year old Palestinian girl who came to international attention for  her  social media updates about life in Gaza.  Baker  was not tied to any political group and  her  perspective on the war was a personal one. Yet  her  social media presence catapulted  her  to global attention and told the Palestinian story to the world in a way that resonated emotionally. It also empowered  Baker  as a political actor  something that  she  had never expected and that could never have occurred in any previous conflict.
During the war  no one was more emblematic of the changing power dynamics than  Farah Baker   a 16-year old Palestinian girl who came to international attention for  her  social media updates about life in Gaza.
Normally  a young teenage girl living under aerial bombardment would have been considered a bystander  at best  or a victim  at worst. But thanks to  her  Twitter feed  where  she  shared both  her  fears as well as  her  attempts to maintain normal life amid the war   Farah  became an important part of the Palestinian effort to sway global opinion on the conflict.
“At only sixteen   Farah  understood  even if only instinctively  the importance of social media in wartime  especially to a perpetual underdog like the Palestinians ” Patrikarikos wrote. “She understood the power that it gave to a single individual and to networks of individuals  power that previously would have been impossible.”
In her own small way  with her tweets and updates during the war   Farah Baker  had played a role in shifting the narrative and forcing the world to grapple with the Palestinian narrative of the conflict.
“I don’t have the ability to carry a weapon and I would never kill anyone  so my only weapon was to broadcast the truth and to let people know what was happening here ”  Baker  told Patrikarakos in an interview at  her  Gaza home. “I was more effective than I ever imagined  because of the amount of followers I got and because so many people told me I had changed their minds [about the war] and opened their eyes.”

Q: SARATOGA SPRINGS  N.Y. (AP) — Before the Army's 27th Infantry Division was decimated in a bloody World War II battle   Stan Dube  sketched portraits of  his  fellow soldiers. The 17 drawings were forgotten after the war and stashed in an attic for decades before being found a year ago by  his  son.
Because the 27th was a former New York National Guard unit   Dube  believes most or all of the other 15 men also were New Yorkers.  He  recently donated the original sketches to the New York State Military Museum and Veterans Research Center in hopes its artifacts and records could be used to help identify more of the soldiers. It's not known whether any of the men depicted in the artwork are still alive.

They were done in Hawaii by Stan Dube in 1943  a year before the 27th Division fought in the Battle of Saipan. Now  his son  Ira Dube   is hoping to identify the men  so  he  has donated  his  late father’s 15 sketches to the museum. (AP Photo/Chris Carola)
 Stan Dube   who died in 2009  was drafted into the Army while studying architecture at Syracuse University  and  he  put  his  drawing skills to use by sketching pencil- and charcoal-on-paper portraits of  his  fellow soldiers while the 27th Division was stationed in Hawaii in 1943.
The sure-handed sketches mostly show young men looking pensively into the distance  though a few crack a smile.  Dube  drew no backgrounds and barely sketched out  his  subjects' shoulders  but  he  took care to capture  his  subjects' eyes and faces.
On all the drawings   Dube  put the month  year and  his  signature in the lower right corner. Three of the soldiers signed their names next to  Dube 's: Kenneth Reid  Joseph Joner Kratky and Joe Orbe  who added his nickname  "Solid Jackson."
Using information he found online   Ira Dube  was able to track down Kratky and Orbe's relatives in upstate New York. Kratky was killed on Saipan in 1944. Orbe  a New York City native  survived the war and died in 1974.  Dube  hasn't definitively identified the soldier in the Reid sketch.
