Sequence-Isomerism-Controlled Macromolecular Self-Assembly in Dendritic Rod-Like Molecules

open access: yes, 2023
Although in Nature sequence control is widely adopted to tune the structure and functions of biomacromolecules, it remains challenging and largely unexplored in synthetic macromolecular systems due to the difficulties in a precision synthesis, which ...

Left Bronchial Isomerism with Right-Sided Tracheal Bronchus: A Rare Case Report

open access: yesDiagnostics, 2023
The tracheal bronchus is a congenital bronchial branching anomaly defined as an aberrant bronchus arising in either the trachea or a main bronchus. Left bronchial isomerism is characterized by two bilobed lungs, bilateral long main bronchi, and both ...

Constitutional isomerism of the linkages in donor–acceptor covalent organic frameworks and its impact on photocatalysis

open access: yesNature Communications, 2022
Systematic investigation of isomerism in covalent organic frameworks (COFs) can provide key insights into their properties. Here, the authors reveal that the constitutional isomerism of the linkage i.e., linkage orientations distinctly impact COFs ...

Genetic disturbances in patients with bodily isomerism from a single center: clinical implications of affected genes and potential impact of ciliary dyskinesia

open access: yesCardiogenetics, 2016
So-called heterotaxy or isomerism is characterized by abnormal lateralization and malformations of the bodily organs. The mechanism is unclear, although there is growing evidence that ciliary dyskinesia is involved.

Partial anomalous hepatic venous drainage into left-sided atrium with right isomerism: A case report with review of literature

open access: yesIndian Journal of Radiology and Imaging, 2017
Right isomerism, also known as Ivemark syndrome, is an unusual degree of symmetry of some of the abdominothoracic viscera reflecting bilateral right-sidedness. We report an exceedingly rare occurrence of anomalous drainage of the left hepatic vein to the
