Input: Consider Input: Context: After a tough win over the Texans, the Steelers stayed home for a game against the Colts. In the first quarter, the Colts scored first as Adam Vinatieri nailed a 31-yard field goal for a 3-0 lead. However, the Steelers took the lead later on in the quarter when Ben Roethlisberger found Markus Wheaton on an 18-yard TD pass for a 7-3 game. In the 2nd quarter, the Steelers would score again increasing their lead as Roethlisberger found Martavis Bryant on a 5-yard TD pass for a 14-3 game. This was followed by William Gay picking off Andrew Luck and returning it 33 yards for a TD as they increased their lead to 21-3. The Colts however responded as Andrew Luck threw a 21-yard TD pass to Dwayne Allen for a 21-10 game. However, the Steelers pulled away as Roethlisberger would find Antonio Brown on 2 consecutive TD passes: from 8 and 47 yards out to increase their lead at first from 28-10 to 35-10. The Colts responded with 10 straight points first being Luck who found T. Y. Hilton on a 28-yard TD Pass for a 35-17 game followed by Vinatieri kicking a 23-yard field goal before halftime to make the score 35-20. The Steelers went back to work in the 3rd quarter as Roethlisberger and Bryant hooked up again on a 2-yard TD pass to increase their lead making the score 42-20. The Colts however were able to come within 8 later on when Ahmad Bradshaw ran for a 12-yard TD followed by Luck finding Donte Moncrief on a 31-yard TD pass to make the score 42-27 and then 42-34. In the 4th quarter, it was all Steelers when a penalty was enforced on Luck in the end zone for a safety making the score 44-34. The Steelers were able to seal the game later on when Roethlisberger found Heath Miller on an 11-yard TD pass for a final score of 51-34. Roethlisberger set franchise records with 522 yards passing and six touchdowns while picking up his 100th victory in his 150th start.

He became the first player in NFL history to go over 500 yards passing twice as the Steelers won consecutive games for the first time this season.

Input: Consider Input: Context: Spleen tyrosine kinase (Syk) is an important modulator of immune signaling. The objective of this phase 2 study was to evaluate the efficacy and safety of R788, an oral inhibitor of Syk, in patients with active rheumatoid arthritis despite methotrexate therapy. We enrolled 457 patients who had active rheumatoid arthritis despite long-term methotrexate therapy in a 6-month, double-blind, placebo-controlled trial. The primary outcome was the American College of Rheumatology (ACR) 20 response (which indicates at least a 20% reduction in the number of both tender and swollen joints and improvement in at least three of five other criteria) at month 6. R788, at a dose of 100 mg twice daily and at a dose of 150 mg once daily, was significantly superior to placebo at month 6 (ACR 20 response rates of 67% and 57%, respectively, vs. 35%; P<0.001 for the comparison of both doses with placebo). It was also significantly superior with respect to ACR 50, which indicates at least a 50% improvement (43% and 32% vs. 19%; P<0.001 for the comparison of the 100-mg dose with placebo, P=0.007 for the comparison of the 150-mg dose with placebo) and ACR 70 (28% and 14% vs. 10%; P<0.001 for the comparison of the 100-mg dose with placebo, P=0.34 for the comparison of the 150-mg dose with placebo). A clinically significant effect was noted by the end of the first week of treatment. Adverse effects included diarrhea (in 19% of subjects taking the 100-mg dose of R788 vs. 3% of those taking placebo), upper respiratory infections (14% vs. 7%), and neutropenia (6% vs. 1%). R788 was associated with an increase in systolic blood pressure of approximately 3 mm Hg between baseline and month 1, as compared with a decrease of 2 mm Hg with placebo; 23% of the patients taking R788 vs. 7% of the patients receiving placebo required the initiation of or a change in antihypertensive therapy. In this phase 2 study, a Syk inhibitor reduced disease activity in patients with rheumatoid arthritis; adverse events included diarrhea, hypertension, and neutropenia. Additional studies will be needed to further assess the safety and efficacy of Syk-inhibition therapy in patients with rheumatoid arthritis.

Input: Consider Input: Context: Speaking and Reading In learning a foreign language, one should first pay attention to speaking. It is the groundwork of reading and writing. You'd better try your best to speak. Don't be afraid of making mistakes. While you are doing this, a good exercise is to write --keep a diary, write notes or letters and so on.

When you are reading in this way, don't stop to look up the words if you can guess their meaning of if they are not important to the sentence. You can do that some other time.
