Although the etiology of thyroid cancer remains unknown and the reasons for the worldwide increase in its incidence are not well understood, exposure to ionizing radiation in childhood [1] and a medical history of goitre or thyroid nodules have been consistently associated with an increased risk. The most common explanation for the marked increase in incidence over time has been the growing use...

We study a dynamic equilibrium search model where sellers differ in their urgency to liquidate an asset. Buyers strategically make price offers without knowing given seller’s urgency. liquidity and dynamics on the transition path after unexpected shock. Generically, includes phase all buyers offer same price, causing market collapse; however, dispersion resumes finite time, leading recovery bot...

The paper surveys some recent developments in the literature which studies continuous-time evolutionary dynamics in the context of economic modeling. JEL CLASSIFICATION NUMBER: C73, C62.

In games with strict strategic complementarities, properly mixed Nash equilibria— equilibria that are not in pure strategies—are unstable for a broad class of learning dynamics. Journal of Economic Literature Classification Numbers: C72, C73.

Site-directed mutagenesis was used to investigate the contribution of disulfide bonds to the antigenic structure of Der p 2. Single amino acid variants were generated at cysteine residues, preventing the formation of disulfide bonds at positions 21-27, 73-78, and 8-119. The variants were tested for binding to murine monoclonal antibodies (mAb) and human IgE antibodies (Ab) in an inhibition enzy...

All histidine tRNA molecules have an extra nucleotide, G-1, at the 5' end of the acceptor stem. In bacteria, archaea, and eukaryotic organelles, G-1 base pairs with C73, while in eukaryotic cytoplasmic tRNAHis, G-1 is opposite A73. Previous studies of Escherichia coli histidyl-tRNA synthetase (HisRS) have demonstrated the importance of the G-1:C73 base pair to tRNAHis identity. Specifically, th...
