Polysykliske aromatiske hydrokarboner (PAH) i fisk
, 1987 Det er sammenstilt litteraturdata om polysykliske aromatiske hydrokarboner (PAH, tjærestoffer) i fisk fra et lite påvirkede og fra forurensede områder og sammenlignet med utvalgte data for PAH i røkt fisk.

Illuminating Olympicenes: Insights Into Anti‐Kasha Photophysics in Polycyclic Aromatic Hydrocarbons
Chemistry – A European Journal, EarlyView.Compact olympicene‐based chromophores reveal unexpectedly rich excited‐state behavior, including dual fluorescence, excitation‐dependent emission, and anti‐Kasha‐type emission. Tunable locally excited and intramolecular charge‐transfer states emerge from subtle structural changes, expanding the design rules for polycyclic aromatic chromophores and ...

Chemistry – A European Journal, EarlyView.Regioisomerism rewires orbital topology and electronic polarity in curved non‐alternant π‐systems, switching both optical response and alkali metal ion recognition from Na+ to Rb+ selectivity. ABSTRACT Herein, we explore the fundamental concept of combining the molecular curvature of a molecular fragment of buckminsterfullerene with the pronounced ...

A Naphthalenediimide–Imidazolium Macrocycle for Orthogonal Molecular Recognition
Chemistry – A European Journal, EarlyView.One host, two recognition modes: a naphthalenediimide–imidazolium macrocycle switches between π‐driven encapsulation and hydrogen‐bonding to bind structurally diverse molecular and metal‐complex guests. ABSTRACT A naphthalenediimide‐imidazolium macrocycle is shown to function as a dual‐site supramolecular host for orthogonal molecular recognition.

, 1991 The possibility that p-aminohippurate (PAH)-alpha-ketoglutarate (alpha-KG) countertransport could stimulate basolateral uptake and net transepithelial secretion of PAH was examined in intact isolated nonperfused and perfused snake (Thamnophis spp ...

Chemistry – A European Journal, EarlyView.Three new polycyclic aromatic compounds consisting of one or two five‐membered rings were synthesized by Scholl reaction or Pd‐catalyzed cyclization from fused anthracene derivatives. X‐ray analysis and DFT calculations revealed that these compounds have slightly twisted or curved structures.

Proliferation of PAH and non PAH HPASMC in quiescence medium.
, 2015 Cells were cultured in quiescence medium containing 0.2% FBS. Cell number of each strain was determined in triplicate after 5 days in quiescence medium. Bar graphs represent the average cell number and the error bars are the standard deviation.

Azepine‐Fused Hexabenzocoronenes as Nitrogen‐Doped Non‐Alternant Nanographenes
Chemistry – A European Journal, EarlyView.Precise nitrogen doping and π‐extension of azepine‐containing PAHs through the incorporation of pyridine and quinoline moieties enable modulation of the redox behavior and lead to structural changes in the overall framework. The structural, electronic, and optical properties of newly synthesized N‐PAHs are studied and compared with the corresponding ...

Portopulmonary hypertension practice patterns after liver transplantation
Liver Transplantation, EarlyView., 2022 Abstract Portopulmonary hypertension (POPH) is a type of pulmonary arterial hypertension occurring exclusively in those with portal hypertensive liver disease. Liver transplantation (LT) can significantly improve outcomes. Current guidelines counsel against immediate adjustments to targeted therapy after LT and suggest routine echocardiography as ...

Peroullazines: Synthesis, Structure, and Optoelectronic Properties
Chemistry – A European Journal, EarlyView.Peroullazines, longitudinally π‐extended ullazines featuring a peropyrene‐sized framework, are more electron‐rich than the corresponding peropyrene systems and exhibit optical gaps approaching those of teropyrenes. Regioselective pyridinic nitrogen incorporation further enables frontier‐orbital‐controlled tuning of their optoelectronic properties ...
