PROBLEM: Totalschaden (Total Damage) is the debut album of the German hip hop artist Tony D. It was released on 14 September 2007 by the label Aggro Berlin.

SOLUTION: What is the name of Totalschaden's record label?

PROBLEM: My grandmother often said to me, "You can count the number of your true friends on the fingers of one hand." For a long time I thought this was true. However, I've now discovered my grandmother was only half right. Maybe we do only make a few "best" friends in our lifetime, but those aren't the only people that we can call friends. There are many different types. Let me tell you about a few of them. One type of friends is the type I call the "football mom friend". My neighbor Sally is a good example. We both have kids who play football in a football club, and someone has to take them to practice and pick them up. Sally and I and two other mothers take turns to do this. We meet sometimes and have tea and talk about what our kids are doing, but those are the only times that we meet each other. I enjoy being with these women, but we don't do anything else together. Another type is called the "hobby friend". That's the person you share an interest or a hobby with. Michael and Cater, who are brothers, are a good example of this type. We're all in a bird watching club. Every few weekends the members of the club go on a trip to watch different kinds of birds. There's nothing romantic about my relationship with Michael and Cater, of course. We just share interest in birds. Then there's the "other half of the couple" type of friends. Jim is married to Rose, a friend that I've known since college. When Rose married Jim, I realized that I would have to be Jim's friend if I want to continue to be Rose's. Jim and I don't share so many interests, but we do have a friendly relationship.

SOLUTION: Many people are mentioned in this passage. Who is the writer's true friend?

PROBLEM: Previously, autosomal dominant catecholaminergic polymorphic ventricular tachycardia (CPVT [1]) was mapped to chromosome 1q42-43 with identification of pathogenic mutations in RYR2. Autosomal recessive CPVT (2) was mapped to chromosome 1p13-21, leading to the identification of mutations in CASQ2. In this study, we aimed to elucidate clinical phenotypes of a new variant of CPVT (3) in an inbred Arab family and also delineate the chromosomal location of the gene causing CPVT (3). In a highly inbred family, clinical symptoms of CPVT appeared early in childhood (7-12 years) and in three of the four cases, the first appearance of symptoms turned into a fatal outcome. Parents of the affected children were first-degree cousins and without any symptoms. Segregation analysis suggested an autosomal recessive inheritance. A genome-wide search using polymorphic DNA markers mapped the disease locus to a 25-Mb interval on chromosome 7p14-p22. A maximal multipoint LOD score of 3.17 was obtained at marker D7S493. Sequencing of putative candidate genes, SP4, NPY, FKBP9, FKBP14, PDE1C, and TBX20, in and around this locus, did not reveal any mutation. We have identified a novel highly malignant autosomal recessive form of CPVT and mapped this disorder to a 25-Mb interval on chromosome 7p14-p22.

SOLUTION:
What is the inheritance pattern of Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT) caused by RYR2 mutations?
