Supramolecular structures and spontaneous resolution: the case of ortho-substituted phenylboronic acids.

Comparative Gas Chromatography of Halides Using Different Substituted Phenylboronic Acids as Derivatizing Reagents

The GC of halides (chloride, bromide and iodide) using phenylboronic acid (PBA), 4-bromophenylboronic acid (BPBA), 3, 5 bis (trifluoromethyl) phenylboronic acid (FPBA) and 2,4- dichlorophenylboronic acid (CPBA) as derivatizing reagents are compared. The reactions are carried out in the presence of mercuric salts. The detection systems used are FID and ECD. The thermal analysis of the compou...

Ortho-azo substituted phenylboronic acids for colorimetric sugar sensors.

The phenylboronic acids substituted with an azo group on the ortho-position show a significant change in UV-vis spectra upon sugar binding. A new mechanism for the spectral change of the dyes is proposed based on the formation and cleavage of B-N dative bond between boronic acid group and azo group.

Spontaneous Resolution of a Fetal Dural Sinus Thrombosis: One Case Report and Review of the Literatures

Sugar-sensitive supramolecular structures based on phenylboronic Acid-modified cyclodextrins.

Supramolecular structures were developed from phenylboronic acid-modified cyclodextrins (PBA-CyDs). The intermolecular interaction between the PBA moiety and the CyD cavity was proved using two dimensional (2D)-NMR and powder X-ray diffraction techniques. PBA-α-CyD formed a head-to-tail supramolecular polymer, whereas PBA-β-CyD formed a head-to-head dimer. The supramolecular structures were dis...

Spontaneous Resolution of Symptomatic Thoracic Spine Calcified Disc Herniation: A Case Report and Literature Review

Calcification of intervertebral disc (IVD) is an uncommon but well-defined clinical syndrome in children. Despite its benign nature, occasionally, calcified nucleus pulposus can herniate into the spinal canal. We report an interesting case of calcified disc herniation in the thoracic spine. Although it resulted in cord compression and syrinx formation, it well responded to conservative manageme...
