[Subfamily of betaherpesviruses as a cause of epithelial and stromal keratitis].

Purpose: This article presents the first clinical results of intravital morphological verification of epithelial and stromal keratitis associated with betaherpesviruses.

Material And Methods: The study group included 12 patients (12 eyes) diagnosed with herpetic keratitis. During the initial visit to the clinic, each patient underwent a standard ophthalmological examination, as well as a number of laboratory tests: immunochemical analysis of blood, molecular diagnostics, and confocal microscopy.

Supramolecular Optimization of Sensory Function of a Hemicurcuminoid through Its Incorporation into Phospholipid and Polymeric Polydiacetylenic Vesicles: Experimental and Computational Insight.

This work presents the synthesis of a new representative of hemicurcuminoids with a nonyloxy substituent () as a fluorescent amphiphilic structural element of vesicular aggregates based on phosphatidylcholine (PC), phosphatidylserine (PS), and 10,12-pentacosadiynoic acid (PCDA). Both X-ray diffraction analysis of the single crystal and H NMR spectra of in organic solvents indicate the predominance of the enol-tautomer of . DFT calculations show the predominance of the enol tautomer in supramolecular assemblies with PC, PS, and PCDA molecules.

Modulating the Inclusive and Coordinating Ability of Thiacalix[4]arene and Its Antenna Effect on Yb-Luminescence via Upper-Rim Substitution.

The present work introduces the series of thiacalix[4]arenes (HL) bearing different upper-rim substituents (R = H, Br, NO) for rational design of ligands providing an antenna-effect on the NIR Yb-centered luminescence of their Yb complexes. The unusual inclusive self-assembly of HL (Br) through Brπ interactions is revealed through single-crystal XRD analysis. Thermodynamically favorable formation of dimeric complexes [2Yb:2HL] leads to efficient sensitizing of the Yb luminescence for HL (Br, NO), while poor sensitizing is observed for ligand HL (H).

Role of PSS-based assemblies in stabilization of Eu and Sm luminescent complexes and their thermoresponsive luminescence.

The present work introduces self-assembled polystyrenesulfonate (PSS) molecules as soft nanocapsules for incorporation of Eu-Sm complexes by the solvent exchange procedure. The high levels of Eu- and Sm-luminescence of the complexes derives from the ligand-to-metal energy transfer, in turn, resulted from the complex formation of Euand Sm ions with the three recently synthesized cyclophanic 1,3-diketones. The structural features of the ligands are optimized for the high thermal sensitivity of Eu- luminescence in DMF solutions.

Single Excited Dual Band Luminescent Hybrid Carbon Dots-Terbium Chelate Nanothermometer.

The report introduces hybrid polyelectrolyte-stabilized colloids combining blue and green-emitting building blocks, which are citrate carbon dots (CDs) and [TbL] chelate complexes with 1,3-diketonate derivatives of calix[4]arene. The joint incorporation of green and blue-emitting blocks into the polysodium polystyrenesulfonate (PSS) aggregates is carried out through the solvent-exchange synthetic technique. The coordinative binding between Tb centers and CD surface groups in initial DMF solutions both facilitates joint incorporation of [TbL] complexes and the CDs into the PSS-based nanobeads and affects fluorescence properties of [TbL] complexes and CDs, as well as their ability for temperature sensing.
