Nucleophilic substitution of a phthalimidyl group with morpholine in an N1‐methyl‐1,2,3‐triazole: crystallographic evidence for migration of the methylene bridge

open access: yesActa Crystallographica Section C, EarlyView.
X‐ray crystallography revealed that the reaction of 2‐{[4‐(4‐bromophenyl)‐1H‐1,2,3‐triazol‐1‐yl]methyl}phthalimide with morpholine led to substitution of the phthalimide group, including migration of the substituent from N1 to N2 on the 1,2,3‐triazole ring.2‐{[4‐(4‐Bromophenyl)‐1H‐1,2,3‐triazol‐1‐yl]methyl}phthalimide, C17H11BrN4O, was synthesized by ...

Prognostic factors of optical coherence tomography angiography in intermediate and advanced primary open‐angle glaucoma: A systematic review and meta‐analysis

open access: yesActa Ophthalmologica, EarlyView.
Abstract Conventional optical coherence tomography (OCT) has a floor effect in patients with severe visual field loss, such as seen in advanced primary open‐angle glaucoma (POAG). OCT angiography (OCTA) does not suffer from such a floor effect. However, which OCTA parameters are most useful for monitoring longitudinal progression is unclear.

Early Maturation of Heart Rate Variability in Very Preterm Infants Depends on Neonatal Factors and Is Associated With Neurodevelopmental Risk

open access: yesActa Paediatrica, EarlyView.
ABSTRACT Aim This study investigated central autonomic network maturation deviations using a previously defined machine learning model set to estimate a functional maturation age (FMA) from heart rate variability (HRV) analysis. We investigated whether these deviations were associated with maternal, fetal, perinatal, or postnatal complications and with

What can lithics tell us about food production during the transition to farming? Exploring harvesting practices and cultural changes during the neolithic in Southwest Asia: a view from Qminas (north‐western Syria)

open access: yesArchaeometry, EarlyView.
Abstract This study examines the continuity and change in harvesting practices between the Late Pre‐Pottery Neolithic B (LPPNB) and the Early Pottery Neolithic at Qminas, north‐western Levant, through a traceological analysis of flint sickles. By combining qualitative traceological analysis with quantitative functional approaches, we demonstrate that ...

Information and affective valence influence judgments of complexity, liking and understanding

open access: yesBritish Journal of Psychology, EarlyView.
Abstract Visual complexity is a key factor in perceptual and evaluative judgments. People's representation of visual complexity is constructed from quantitative and structural image features, but it is also influenced by familiarity and expertise. We examined how people represent visual complexity and its impact on perception and evaluation, focusing ...
