[EX Q]: The company had an IPO on the NASDAQ in 1996 and in 1997 Europe's largest telecommunications company, Deutsche Telekom, bought a 21.1 percent stake in VocalTec for $48.3 million, in addition to purchasing $30 million in telephony products, services, and support over the following two-and-a-half years.

[EX Q]: Restless legs syndrome is a neurological disorder characterized by an urgency to move the legs during periods of rest. Data from a variety of sources provide a compelling argument that the amount of iron in the brain is lower in individuals with restless legs syndrome compared with neurologically normal individuals. Moreover, a significant percentage of patients with restless legs syndrome are responsive to intravenous iron therapy. The mechanism underlying the decreased iron concentrations in restless legs syndrome brains is unknown. We hypothesize that the source of the brain iron deficit is at the blood-brain interface. Thus we analysed the expression of iron management proteins in the epithelial cells of the choroid plexus and the brain microvasculature in post-mortem tissues. The choroid plexus, obtained at autopsy, from 18 neurologically normal controls and 14 individuals who had primary restless legs syndrome was subjected to histochemical staining for iron and immunostaining for iron management proteins. Iron and heavy chain ferritin staining was reduced in the epithelial cells of choroid plexus in restless legs syndrome. Divalent metal transporter, ferroportin, transferrin and its receptor were upregulated in the choroid plexus in restless legs syndrome. Microvessels were isolated from the motor cortex of 11 restless legs syndrome and 14 control brains obtained at autopsy and quantitative immunoblot analyses was performed. Expression of heavy chain ferritin, transferrin and its receptor in the microvessels from restless legs syndrome was significantly decreased compared with the controls but divalent metal protein 1, ferroportin, prohepcidin, mitochondrial ferritin and light-chain ferritin remained unchanged. The presence of an iron regulatory protein was demonstrated in the brain microvasculature and the activity of this protein is decreased in restless legs syndrome; a finding similar to our earlier report in neuromelanin cells from the substantia nigra of restless legs syndrome brains. This study reveals that there are alterations in the iron management protein profile in restless legs syndrome compared with controls at the site of blood-brain interface suggesting fundamental differences in brain iron acquisition in individuals with restless legs syndrome. Furthermore, the decrease in transferrin receptor expression in the microvasculature in the presence of relative brain iron deficiency reported in restless legs syndrome brains may underlie the problems associated with brain iron acquisition in restless legs syndrome. The consistent finding of loss of iron regulatory protein activity in restless legs syndrome brain tissue further implicates this protein as a factor in the underlying cause of the iron deficiency in the restless legs syndrome brain. The data herein provide evidence for regulation of iron uptake and storage within brain microvessels that challenge the existing paradigm that the blood-brain barrier is merely a transport system.
[EX A]: Which deficiency is the cause of restless leg syndrome?

[EX Q]: The two most popular teams in Peru are Universitario and Alianza Lima. They are at the top of the polls conducted by many different groups. The group Apoyo, Opinion y Mercado in 2006 revealed that Alianza Lima was popular amongst 35%, followed by Universitario, with 32%. In 2005, a study by Grupo de Opinion Publica de la Universidad de Lima showed that Universitario was the most popular team in Lima and Callao with 31.7% followed by Alianza Lima with 29.3%. However, in 2006 and 2007 Alianza Lima appeared first in their polls. There was a narrow margin in 2007 as Alianza Lima reached 29.6% and Universitario followed with 29.5% under a margin of error of 4.16% In 2009, the universitys results varied because Alianza reached first with 40% and Universitario second with 35.5% under a margin of error of 4.47%. Another group known as CPI, revealed in May 2008 that Universitario was favored by 32% whilst Alianza Lima was favored by 33.5% under a margen of error of 2.7% at the national level. This report was divided into two parts. In the metropolitan capital, Universitario led with 42.8% and Alianza tailed behind with 39.9%. In the rest of the country, Universitario had a larger lead with 31.5% opposed to Alianzas 24.1%. In 2009, CPI released another poll indicating the Universitario was still the most popular team in Peru with 38.6% while Alianza reached 33.1%. A survey conducted by Grupo de Opinion Publica de la Universidad de Lima in February 2009, said that Alianza Lima ranked first in popularity with 27.2%; Universitario second with 26.6%. However, a second poll released by the same university group in September of the same year ranked Universitario first with 37.9% and Alianza second with 36.6%. The most recent report from the group indicates that Universitario has more sympathizers than Alianza with 40.6% over 36.% in the Province of Lima and Callao. On 2010, South American Football Confederation (Conmebol) stated that Universitario is the most popular team in Peru.
[EX A]:
In a 2005 poll, was Alianza Lima or Universitario more popular?
