[Q]: A novel Ca2+/calmodulin-dependent protein kinase II (CaM Kinase II) inhibitor, KN-93 potently inhibits gastric acid secretion from parietal cells. As previously reported (1), treatment of parietal cells with a selective inhibitor of CaM kinase II, KN-62 resulted in the inhibition of cholinergic-stimulated rabbit parietal cell secretion, whereas it failed to inhibit the histamine and forskolin response. In contrast effects of carbachol, histamine and forskolin were significantly inhibited by KN-93 with an IC50 of 0.15, 0.3 and 1 microM, respectively; these effects occurred without any changes in intracellular cyclic AMP and Ca2+ levels. In the present study we investigated the mechanism by which KN-93 acts upon the acid-secreting machinery of gastric parietal cells. Neither redistribution of the proton pump activity nor the morphological transformation were affected by KN-93. The drug only weakly inhibited the H+, K(+)-ATPase activity but strongly dissipated the proton gradient formed in the gastric membrane vesicles and reduced the volume of luminal space. Thus KN-93 acts at pH gradient formation whereas KN-62 acts only at CaM Kinase II.
[A]: Which kinase is inhibited by the small molecule KN-93?


[Q]: The spin-off movie focuses on Matt Stifler (Tad Hilgenbrinck), the younger brother of Steve Stifler from the previous American Pie films. Matt is eager to enter the family business of making porno films, so he can prove to his older brother that he is "up to the standards of the Stifmeister." Stifler and his friends play a prank on the band students during the seniors' graduation ceremony by spraying pepper spray on the mouthpieces of the band's instruments. Matt narrowly escapes getting caught and stows the can of pepper spray in his front pocket, which subsequently leaks onto his genitals. The band members begin to play "Pomp and Circumstance", only to become too irritated by the pepper spray to continue. During the commotion, one of the students trips and pulls down the back curtain, which reveals Matt, who is washing his pepper-spray-soaked genitals in a drinking fountain, in front of the whole school.The band leader Elyse Houston (Arielle Kebbel) demands that Stifler be punished for ruining their performance, stating that he always gets away with his pranks because he is the school's star football player. The school's guidance counselor Chuck Sherman ("The Sherminator") (played by Chris Owen from the original American Pie films) decides that a worthwhile punishment would be for Stifler to attend band camp, in the hopes that he would make friends with the "bandies" and not follow in the footsteps of his much-hated brother.When first arriving, Matt is very disrespectful to the rules and also everyone at Tall Oaks and gets his band group in trouble. He is sent to the office of Noah Levenstein (Jim's father) (Eugene Levy), who works as the camp MACRO (Morale and Conflict Resolution Officer; he's filling in for Michelle as she is now pregnant), recommends that he try to fit in and earn the band's trust, which is the last thing that Matt wants to do. However, a phone call from a friend, who says that earning their trust will get him better footage for his video, inspires Matt to be much more respectful and humble towards the band.Matt finds out that his dorky roommate Ernie Kapolwitz (Jason Earles) has an extensive knowledge of spy cameras and technology, so Matt agrees to let him help with the filming, making his first friend at Tall Oaks. As Matt "is earning the band's trust" he gets into a big confrontation with their rival band leader, Brandon Van der Camp (Matt Barr), and even goes as far as to accept a duel challenge made by him, having no idea what a "duel" is.It turns out that a duel is the two performers showing off their music skills, with Brandon playing the snare drum, and Matt playing the triangle. Throughout the majority of the competition it seems that Brandon is the heavy favourite; during Brandon's second round of performing, Matt walks away humiliated. As Brandon is about to be declared the official winner, Matt comes back playing the bagpipes to the tune of 'Play That Funky Music' showing that he is actually a decent player, surprising everyone, including Elyse, who is pleasantly surprised by Matt's performance.As Matt is still recording the various happenings at the camp, he gradually becomes friends with some of the band members from his school. He gains some respect from Ernie after Matt sets him up on a date with tattooed bandmate Chloe (Crystle Lightning). Matt starts falling for Elyse, who is revealed to have been a friend of Matt's in 8th grade but had a falling out after Matt started hanging around with Steve and his friends and acting like The Stifmeister. Matt is eventually caught with his movies, and his once-friends want nothing more to do with him.After another talk with Jim's Dad, Matt comes to realize that his brother is not as great or cool as he once thought and that following in his footsteps is not a good idea, so he deletes all the videos he recorded at band camp. He even enlists the help of the band to help Elyse get the band scholarship that Stifler

[Q]: The most popular names in the west Every year in Englishspeaking countries,people list the most popular names. Here are some examples. In the United States at the moment the three most popular names for girls are Emily,Emma and Madison. For boys,they are Michael,Joshua and Mathew. In Britain a parent today might call their little girl Grace,Jessica or Ruby. If they have a little boy they could call him Jack,Thomas or Oliver. In China names have very clear meanings. If a girl is called Mei,her name means "beautiful". If a boy is called Wu,his name means "like a soldier". Names in Englishspeaking countries are like this too. The girl's name Joy is probably partly chosen because the parents wish their daughter to be joyful and bring joy to others. If a girl is called Ruby,it may be because of the beautiful red precious stone. Parents often pick names that can be shortened. This can be confusing for Chinese people. Parents might choose such names because they want to be able to speak to their kid in a personal way. For example,a popular name is William. But William can be shortened to Will,Willy,Bill and Billy. The same is true of the favourite old name for a girl,Elizabeth. Elizabeth can be shortened to Beth,Liza and Liz. Another reason why kids get the names they do is that parents want to name their boy or girl after someone who is famous,such as an actor,a pop music star or a sports star. David is a popular name in Britain,partly because of the fame of the footballer David Beckham.
