PROBLEM: 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

SOLUTION: Who is the younger brother of Steve Stifler?

PROBLEM: Sam Gillen (Van Damme) is a convict who gets sprung from Federal custody somewhere in the Midwest by his bank-robbing partner. In their last heist, Sam's partner killed a bank guard, and Sam took the rap for it. Sam's partner gets killed in the break, forcing Sam to go it alone in search of the loot, which is buried on the property of a farm inhabited by Clydie Anderson (Arquette), the widowed mother of two kids named Mike "Mookie" Anderson and Bree Anderson.Attempting to sneak into Clydie's house and "borrow" some salt for a campfire-broiled steak, Sam catches sight of Clydie taking a shower. The next morning, Sam is spotted bathing outdoors by Mookie. After saving Clydie, Mookie, and Bree from a trio of intruding thugs, Sam discovers that Clydie is holding out from selling her place to property developer Franklin Hale, who fears that he will be put out of business if he doesn't get Clydie's land so he can develop on it.Sam decides to hang around, sleeping first in Clydie's barn and then in her bed while repairing her late husband's Triumph motorcycle. And Hale hires an intimidation expert named Dunston, to force Clydie into selling her land. Secretly on Hale's payroll is corrupt sheriff Lonnie Cole, a sometime lover of Clydie.A jealous Lonnie discovers Sam's true identity and threatens to expose him if he doesn't leave. Not wanting to place Clydie in additional danger for helping a fugitive, Sam decides to leave, only to find that Hale has already blown the whistle on him in an attempt to get him out of the way. After evading police chasing him in cars, land rovers, helicopters, and on motorcycles and horseback, Sam returns to save Clydie from Dunston and Hale, who are planning to burn down her house.After fighting off the bad guys and getting Hale caught holding a gun to Clydie's head, he decides to turn himself in, rather than run away. He promises to be back to live with them.

SOLUTION: Who spots Sam bathing outdoors ?

PROBLEM: Antisense therapy with both chemistries of phosphorodiamidate morpholino oligomers (PMOs) and 2'-O-methyl phosphorothioate has demonstrated the capability to induce dystrophin expression in Duchenne muscular dystrophy (DMD) patients in phase II-III clinical trials with benefit in muscle functions. However, potential of the therapy for DMD at different stages of the disease progression is not understood. In this study, we examined the effect of peptide-conjugated PMO (PPMO)-mediated exon skipping on disease progression of utrophin-dystrophin-deficient mice (dko) of four age groups (21-29, 30-39, 40-49 and 50+ days), representing diseases from early stage to advanced stage with severe kyphosis. Biweekly intravenous (i.v.) administration of the PPMO restored the dystrophin expression in nearly 100% skeletal muscle fibers in all age groups. This was associated with the restoration of dystrophin-associated proteins including functional glycosylated dystroglycan and neuronal nitric synthase. However, therapeutic outcomes clearly depended on severity of the disease at the time the treatment started. The PPMO treatment alleviated the disease pathology and significantly prolonged the life span of the mice receiving treatment at younger age with mild phenotype. However, restoration of high levels of dystrophin expression failed to prevent disease progression to the mice receiving treatment when disease was already at advanced stage. The results could be critical for design of clinical trials with antisense therapy to DMD.

SOLUTION:
In what percentage of skeletal muscle fibers is dystrophin expression restored after PPMO- mediated exon skipping?
