The isotopic analysis of boron from material that carries only trace amounts of boron requires low boron blank levels. Large efforts are taken to keep blank levels low by purifying reagents. We performed exposure experiments and determined procedure blanks before and after the air-handling system was modified from silicate glass filters to polyethylene/polystyrole and active carbon filters. Our...

Notions of unambiguity for uniform circuits and AuxPDAs are studied and related to each other. In particular, a coincidence for counting and unambiguous versions of AuxPDAs and semi-unbounded fan-in circuits is shown. Moreover, an improved simulation of LOGUCFL (the class of languages logspace many-one reducible to unambiguous context-free languages) by unambiguous circuits and AuxPDAs is devel...

Sclerosis and increased matrix expression in diabetes are mediated by glucose-induced transforming growth factor (TGF)1 expression. The intracellular effects of high glucose occur at least in part by way of protein kinase C (PKC). We previously described a role for PKCin glucose-induced permeability. We now investigated the hypothesis that glucose-induced expression of TGF1 and its receptors (T...

Response to Rolf Zinkernagel and Paul Klenerman

How did it start? It began in 1976 with a meeting over a glass of beer between Bob Swanson, then a bright young venture capitalist, and Herb Boyer (UCSF), who with Stan Cohen (Stanford) had just performed some of the key experiments of recombinant DNA technology. The meeting is now immortalized in a brass statue in the new Founders’ Research Center. Genentech was founded later that year, and cl...
