Question: How often are new issues of the Canadian Journal of Neurological Sciences published? Passage:Multi-dose versions of the vaccine contain the preservative thiomersal (also known as thimerosal), a mercury compound that prevents contamination when the vial is used repeatedly. Single-dose versions and the live vaccine do not contain this preservative. In the U.S., one dose from a multi-dose vial contains approximately 25 micrograms of mercury, a bit less than a typical tuna fish sandwich. In Canada, different variants contain five and 50 micrograms of thimerosal per dose. The use of thiomersal has been controversial, with claims that it can cause autism and other developmental disorders. The U.S. Institute of Medicine examined these claims and concluded in 2004 that the evidence did not support any link between vaccines and autism. Other reviews came to similar conclusions, with a 2006 review in the Canadian Journal of Neurological Sciences stating that there is no convincing evidence to support the claim that thimerosal has a causal role in autism, and a 2009 review in the journal Clinical Infectious Diseases stating that claims that mercury can cause autism are "biologically implausible". The U.K. National Health Service stated in 2003 that "There is no evidence of long-term adverse effects due to the exposure levels of thiomersal in vaccines." The World Health Organization concluded that there is "no evidence of toxicity in infants, children or adults exposed to thiomersal in vaccines". Indeed, in 2008 a review noted that even though thiomersal was removed from all US childhood vaccines in 2001, this has not changed the number of autism diagnoses, which are still increasing.

question:
Question: What were the names of the members of the group that sang "West End Girls"? Passage:The singing is done in soft British Received Pronunciation-style accents in the style of the Pet Shop Boys and their song "West End Girls", with Samberg additionally comparing the beat to the works of producer Timbaland. The video opens with Samberg in a night club singing as he is about to hit on a girl (Molly Sims). They head to her apartment, share a kiss in the hallway outside her door, but once she says that "she wants some more" (i.e. sex), he "jizzes" prematurely. He refuses to apologize, saying it would be "absurd" and blames the girl for overstimulating him by rubbing his "butt", before he goes home "and change[s]". Taccone is then shown in a grocery store (where Justin Timberlake makes a cameo appearance as a janitor) conversing with a check-out girl (Jamie-Lynn Sigler), but jizzes in his pants as well when she asks, "cash or credit?" After explaining that the way she bags cans got him "bothered and hot", he tells her that he will pay by check.
