Synthesis of Cross-Chain Bridging Cryptands and Induction of Molecular Chirality.

In this study, we synthesized two cryptands featuring entangled tri- and tetra(ethylene glycol) linkers. The cryptand bearing short linkers was chiral without any asymmetric carbon atoms. After chiral high-performance liquid chromatography was used to separate the enantiomers, the absolute configuration of each cryptand was determined through single-crystal X-ray and circular dichroism analyses.

[A case of septic pulmonary embolism with endogenous endophthalmitis in a healthy adult].

A 56-year-old man with chief complaints of reduced visual acuity in the left eye and an 8-day history of pyrexia was diagnosed with uveitis at a nearby hospital, and was referred and admitted to our hospital. Two days after admission, he complained of dyspnea. Chest X-ray revealed an infiltrative shadow in the right middle pulmonary field and right pleural effusion.

Measurement of vitamin D-binding protein in pleural fluids and sera by means of a turbidimetric immunoassay measuring system.

Background: Vitamin D-binding protein (DBP) has been recognized as a multifunctional plasma protein that can modulate certain immune and inflammatory responses. There may be differences between the DBP concentrations in pleural fluids from various diseases involving a variety of possible responses in the pleural cavity.

Methods: An anti-DBP polyclonal antibody was prepared using commercially available DBP to establish a quantitative measuring system for DBP.
