Selenazolidine: a selenium containing proline surrogate in peptide science.
In the search for new peptide ligands containing selenium in their sequences, we investigated l-4-selenazolidine-carboxylic acid (selenazolidine, Sez) as a proline analog with the chalcogen atom in the γ-position of the ring. In contrast to proteinogenic selenocysteine (Sec) and selenomethionine (SeMet), the incorporation within a peptide sequence of such a non-natural amino acid has never been...
متن کاملAtherosclerosis Surrogate Marker in Diabetic Patients
Objective: Duplex ultrasonography is a non-invasive, non-expensive screening test for carotid disease. Intima media thickness (IMT) is appropriate for atherosclerosis process diagnosis. Leukoaraisis (LA) increase the risk of cerebrovascular accident (CVA). LA patients need preventive medication for CVA. IMT is a non-invasive diagnostic and prognostic test in LA. The aim of this study was evalua...
متن کاملSurrogate Constraints
A surrogate constraint is an inequality implied by the constraints of an integ~r program, and designed to capture useful information that cannot be extra~ted from the parent constraints individually but is nevertheless a consequepce of their conjunction. The use of such constraints as originally propo~ed by the author has recently been extended in an important way by EGON! BALAS and ARTHUR GEOF...

متن کاملSurrogate time
Before we apply nonlinear techniques, for example those inspired by chaos theory, to dynamical phenomena occurring in nature, it is necessary to rst ask if the use of such advanced techniques is justiied by the data. While many processes in nature seem very unlikely a priori to be linear, the possible nonlinear nature might not be evident in speciic aspects of their dynamics. The method of surr...
