Q: "We don't necessarily believe that new advertising, which might make consumers feel better about the Coke brand or better about the ads themselves , will actually result in consumers consuming more of the product," Morgan Stanley's Bill Pecoriello wrote in a research note the days after the investor meeting . But Coke is optimistic it can regain its old magic, and is banking on a new slogan: "Welcome to the Coke side of life." BREAK THROUGH HIT? With PepsiCo about to surpass Coke as the beverage king on Wall Street--Pepsi's market capitalization has _ in recent years to $97.9 billion, putting it less than a billion dollars behind its rival--the heat is on Coke . It's set to launch a new marketing campaign in March, 2006. And having taken a quick look at Coke's investor presentation on Dec. 7 in New York, my sense is that Coke may be moving in the right direction . Given the continued shift by consumers away from soda--Coke's stronghold --and into alternative beverages like juice, tea, and water, Coke badly needs a breakthrough hit. And given that shift away from soda, some analyists wonder whether even the catchiest new ads will be enough to put the fizz back into Coke. SAME OLD, UPDATED? The new flavors of PowerAde sports drink will probably enable Coke to continue stealing market share from PepsiCo's Gatorade brand. And Coke is getting a little more creative with packaging, including new, aluminum bottles of Coke that will be sold in nightclubs, and an 8.4-ounce "100 calorie" version of its flagship Coke that will appeal to women who want fewer calories and will like the fact that the small can will fit in their purse. I doubt whether other new products will be successful, including a new coffee-flavored soda called Coke-Cola Black that I tried. Think carbonated coffee. But I'm not sure if the product, which Coke is pitching as an afternoon pick-me-up for the 35-and-over set, is going to pull people away from their afternoon Frappucino fix. And my opinion is that Vault, an orange-flavored energy drink, will have just as much trouble unseating Mountain Dew among teens as did Coke's last attempt, a product called Surge. If there is one concern I have about the fresh offerings Coke plans to launch this year, it appears that many of them are simply new brands, not new products.

Q: When reporter ANN MITCHELL is laid off by managing editor HENRY CONNELL because of streamlining, she begs to stay on since she's supporting her MOTHER and TWO SISTERS, but it's no use. Angry, she gathers up her belongings but then, as a parting shot, types up a fake letter from "John Doe" stating that he's so downtrodden by the unfairness of things that he intends jumping off the building on Christmas Eve.The paper prints the letter and it causes a sensation. Everyone relates to and wants to help John Doe. Connell, desperate to get hold of the original letter is shocked when Ann tells him there was no letter. Connell, angry, is ready to print a retraction but Ann suggests that they hire a "fake John Doe" to embody the pathos of the letter. She gets her job back along with a lucrative fee and contract.Several desperate MEN line up claming to have written the letter, so Ann and Connell must now pick the one. When handsome JOHN WILLOUGHBY walks in, Ann's clearly smitten. A likeable, quiet baseball player who's fallen on bad times, John's the one who will become "John Doe." Although he seems too honest to lie, Ann believes he's desperate enough. They create a fake letter, put him up at a fancy hotel with bodyguards, making him sign an agreement. Also in tow (much to Connell's chagrin) is THE COLONEL, a confirmed vagabond, distrustful of society, who warns John that he's falling into a trap of privilege.Next come publicity photos, which are directed by Ann to get the correct "angry protest" look. With headlines proclaiming his anger at the unfairness of the world, John becomes an increasing media sensation, courtesy of hyperbolic headlines concocted by Connell. Meanwhile, the GOVERNOR suspects John Doe is a myth but mistakenly feels it was concocted by publisher B. D. NORTON to discredit him. Ann convinces Norton to play it for what it's worth. Norton offers her money to write radio speeches to sell Doe. He also wants her to work directly with him and not Connell.Ann goes to work, typing up a storm but nothing comes to mind. Ann's Mother suggests that she write something upbeat and simple, using the values of Ann's late father as an inspiration. By now, John has begun realizing that his baseball career might not get started again if the John Doe business is revealed as a phony.Nonetheless, John reads his first manufactured upbeat speech, written by Ann to a packed house. Ann coaches him to be sincere, suggesting that she's fallen in love with John Doe. The speech, broadcast on the radio, stirs the people with its "love thy neighbor"-style message. CROWDS love him but John can't get away fast enough. He and the Colonel resort to the boxcars and flee. B. D. Norton, thinking he was great, wants him located.When a DINER WAITER recognizes him, John's hope for a return to normalcy is squelched by sudden CROWDS, eager to meet him. Ann and Norton locate him. John isn't happy about it. When Norton offers him a lecture tour, he refuses it angrily. When the common PEOPLE who have a "John Doe" club talk to him, however, he softens when hearing how he's touched them. Now, John's torn. His itinerant pal, The Colonel, thinks he's been "hooked" and, disgusted, walks out on him.Norton arranges the lecture tour. John speaks in state after state, addressing the many national clubs in his name. Connell tells Norton, however, that he's curious why Norton is spending so much money on the tour. In the meantime, Ann, knowing that John now likes her, feels increasingly like the heel she feels she is. She feels even worse when John relates a tender dream that he had about her and talks to her about how he relates to the lonely, hungry people to whom he's been speaking.Norton gives Ann a fur coat and a gift. He then tells her that he wants John Doe to announce a

Q: Heme is critical for a variety of cellular processes, but excess intracellular heme may result in oxidative stress and membrane injury. Feline leukemia virus subgroup C receptor (FLVCR1), a member of the SLC49 family of four paralogous genes, is a cell surface heme exporter, essential for erythropoiesis and systemic iron homeostasis. Disruption of FLVCR1 function blocks development of erythroid progenitors, likely due to heme toxicity. Mutations of SLC49A1 encoding FLVCR1 are noted in patients with a rare neurodegenerative disorder: posterior column ataxia with retinitis pigmentosa. FLVCR2 is highly homologous to FLVCR1 and may function as a cellular heme importer. Mutations of SLC49A2 encoding FLVCR2 are observed in Fowler syndrome, a rare proliferative vascular disorder of the brain. The functions of the remaining members of the SLC49 family, MFSD7 and DIRC2 (encoded by the SLC49A3 and SLC49A4 genes), are unknown, although the latter is implicated in hereditary renal carcinomas. SLC48A1 (heme responsive gene-1, HRG-1), the sole member of the SLC48 family, is associated with the endosome and appears to transport heme from the endosome into the cytosol.

A:
Which SLC family is FLVCR1 a member of?
