We propose and experimentally demonstrate a ring resonator with sharp U-turns fabricated on a silicon-on-insulator (SOI) substrate; the resonator was designed as a key part of an optical, dynamic data storage device. We discuss the optical properties

This paper investigates the optical characteristics of a light-focusing device (LFD) consisting of two-dimensional (2-D) photonic crystals (PCs) configured in a parallelogram lattice structure. The LFD is composed of two jointed symmetric PCs that ha

A U-shaped trimeric porphyrin array with a zinc/free-base/zinc arrangement (5ZFZ) and its derivatives were synthesized in order to investigate the interacting porphyrins in organic solvents. The porphyrin array is comprised of an αα-atropisomeric b

To examine the mechanism behind a decrease in type 1 iodothyronine deiodinase (D1) gene expression in diabetes mellitus, we evaluated the effect of administering T3 and/or insulin on D1 activity and the mRNA levels in the liver of streptozotocin (STZ

We report a 62-year-old male patient who had variant angina and isolated adrenocorticotropic hormone(ACTH) deficiency. His serum sodium concentration was low and vasopressin was inappropriately high for the low plasma osmolality. Serum free thyroxine
