Taxonomic corrections and new records for vascular plants of Kyrgyzstan, 6

open access: yesNordic Journal of Botany, EarlyView.
A series of notes on taxonomy, nomenclature, morphology and distributions of native species of vascular plants in Kyrgyzstan is presented. Anaphalis roseoalba is treated as a synonym of A. virgata; Hippolytia herderi and H. megacephala are new synonyms of H. senecionis; Hippolytia darvasica and H. schugnanica are new synonyms of H. tomentosa; Campanula

Effect of Surgical Specialty on Postoperative Complications of Rhinoplasty

open access: yesOtolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective Rhinoplasty is a cosmetic procedure that is typically performed by either otolaryngologists (ear, nose, and throat [ENT]) or plastic surgeons. This study specifically investigates the association between surgical specialty and complications in rhinoplasty. Study Design Retrospective database review. Setting US hospitals.

Elucidating the Three‐Dimensional Structure of Piracetam through Rotational Spectroscopy

open access: yesChemistryOpen, EarlyView.
Neutral molecules of the nootropic drug piracetam are generated by laser ablation and structurally characterized by microwave spectroscopy. Two conformers differing in the exo/endo configuration of the pyrrolidine ring are detected, with exo being the predominant form.

Asymmetric Ketocyanine Dyes with an Extended Polymethine Chain

open access: yesChemistryOpen, EarlyView.
This work is dedicated to the synthesis and investigation of the structure, spectral and fluorescent properties of new asymmetric long‐chain ketocyanine dyes. It has been shown also that these compounds can serve as convenient precursors for the synthesis of highly asymmetric polymethine dyes, which exhibit large Stokes shifts and comparatively bright ...

One‐Pot Four‐Component Synthesis of Novel Amino‐Tetrahydro‐Chromene Derivatives Anchored with Dual Triazole Moieties

open access: yesChemistryOpen, EarlyView.
A series of tetrahydrochromene derivatives bearing triazole rings is synthesized via a one‐pot reaction. The process is optimized by ultrasonication of a basic aqueous tert‐butanol mixture. Subsequently, the optimized steps are successfully integrated into a four‐component, one‐pot protocol. The whole process was completed in less than 2 h.
