This paper develops a general equilibrium exchange rate model consistent with the weak empirical evidence supporting the law of one price. Some firms segment markets by country, and set prices in local currency of sale, a practice we refer to as pricing-to-market (PTM). The presence of PTM increases exchange rate volatility, relative to a situation where the law of one price holds. PTM also aff...

dbPTM is a database that compiles information on protein post-translational modifications (PTMs), such as the catalytic sites, solvent accessibility of amino acid residues, protein secondary and tertiary structures, protein domains and protein variations. The database includes all of the experimentally validated PTM sites from Swiss-Prot, PhosphoELM and O-GLYCBASE. Only a small fraction of Swis...

Tyrosine O sulfation is a post translational modification (PTM) originally discovered by Bettelheim in 1954 in the bovine protein fibrinogen. Currently, this PTM is found only in secreted and transmembrane proteins of higher eukaryotes. This article gives an overview of experimental tools to study tyrosine O sulfation and also describes the biological function of this PTM.

Thoroughbred horses develop extremely high pulmonary vascular pressures during galloping, all horses in training develop exercise-induced pulmonary hemorrhage, and we have shown that this is caused by stress failure of pulmonary capillaries. It is known that the capillary transmural pressure (Ptm) necessary for stress failure is higher in dogs than in rabbits. The present study was designed to ...

Platensimycin (PTM) and platencin (PTN) are potent and selective inhibitors of bacterial and mammalian fatty acid synthases and have emerged as promising drug leads for both antibacterial and antidiabetic therapies. Comparative analysis of the PTM and PTN biosynthetic machineries in Streptomyces platensis MA7327 and MA7339 revealed that the divergence of PTM and PTN biosynthesis is controlled b...

Detailed characterization of post-translational modifications (PTMs) of proteins in microbial communities remains a significant challenge. Here we directly identify and quantify a broad range of PTMs (hydroxylation, methylation, citrullination, acetylation, phosphorylation, methylthiolation, S-nitrosylation and nitration) in a natural microbial community from an acid mine drainage site. Approxi...

This paper introduces new notions of asymptotic proofs, PT(polynomial-time)extensions, PTM(polynomial-time Turing machine)-ω-consistency, etc. on formal theories of arithmetic including PA (Peano Arithmetic). An asymptotic proof is a set of infinitely many formal proofs, which is introduced to define and characterize a property, PTM-ω-consistency, of a formal theory. Informally speaking, PTM-ω-...

BACKGROUND Prosthesis-patient mismatch (P-PtM) after aortic valve replacement results in disturbed valve performance associated with increased pressure gradients. However, it is unknown whether this can be related to future structural valve deterioration (SVD) of the bioprosthesis. METHODS AND RESULTS In 564 patients (mean age, 74+/-5 years) receiving an aortic valve bioprosthesis, clinical f...

To the Editor: Pretibial myxedema (PTM), a localized thyroid-associated dermopathy, is characterized by local thickening and remodeling of the skin − it is often associated with a group of autoimmune thyroid diseases (ATDs).[1] PTM is most frequently located across the lower legs, especially the pretibial areas or the dorsum of the foot. Rarely, the fingers and hands, elbows, arms, or face are ...

Post-translational modifications (PTMs) are involved in the regulation and structural stabilization of eukaryotic proteins. The combination of individual PTM states is a key to modulate cellular functions as became evident in a few well-studied proteins. This combinatorial setting, dubbed the PTM code, has been proposed to be extended to whole proteomes in eukaryotes. Although we are still far ...
