CFTR (cystic fibrosis transmembrane conductance regulator), the protein whose dysfunction causes cystic fibrosis, is a chloride ion channel whose gating is controlled by interactions of MgATP with CFTR's two cytoplasmic nucleotide binding domains, but only after several serines in CFTR's regulatory (R) domain have been phosphorylated by cAMP-dependent protein kinase (PKA). Whereas eight R-domai...

A 14-year-old boy was admitted with a five-day history of progressive weakness affecting all four limbs. Three weeks earlier he had developed a productive cough which had been successfully treated with talampicillin. He suffered from asthma and was receiving sodium cromoglycate. On examination there was widespread inspiratory wheeze and a flaccid tetraparesis with relative sparing of distal mus...

BACKGROUND The Office of Advanced Molecular Detection (OAMD), Centers for Disease Control and Prevention (CDC), manages a Twitter profile (@CDC_AMD). To our knowledge, no prior study has analyzed a CDC Twitter handle's entire contents and all followers. OBJECTIVE This study aimed to describe the contents and followers of the Twitter profile @CDC_AMD and to assess if attaching photos or videos...

. Abstract We have developed a Clock Multiplying Unit and 4 to 1 Multiplexor (CMUIMUX 4:l) that operates up to 47Gb/s. The on board VCO is LC tuned and the output clock jitter is Lpspp. The eye diagram of the output is 400mV swing with rise and fall times of less than 9ps. This integrated circuit was processed in a 120GHz BICMOS 0.25um process. Power dissipation is only 1W for a chip area of Zm...
