Ion Mobility–Mass Spectrometry Imaging: Advances in Biomedical Research [PDF]

BioTech
Mass spectrometry imaging (MSI) visualizes the spatial distribution of biomolecules in tissues, whereas ion mobility–mass spectrometry (IM-MS) separates ions through the collision cross-section (CCS) with an inert gas, providing the structural ...

Left Isomerism With Normal Bronchopulmonary Anatomy: Broadening the Heterotaxy Spectrum [PDF]

Case Reports in Radiology
Situs ambiguous is a rare congenital condition characterized by the abnormal arrangement of thoracoabdominal organs along the left–right axis. This condition often presents as either left or right isomerism, leading to complex anatomical variations and ...

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

Nature 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 ...

Left isomerism with bilateral superior vena cava, interrupted inferior vena cava and tetralogy of Fallot

Annals of Pediatric Cardiology, 2020
The association of left isomerism with tetralogy of Fallot (TOF) is rare and reported as scattered case reports. Complex congenital cardiac and noncardiac malformations are known to be associated with left isomerism, but right-sided obstructive lesions ...

The Development and Validation of a Targeted LC-HRAM-MS/MS Methodology to Separate and Quantify p-Synephrine and m-Synephrine in Dietary Supplements and Herbal Preparations

Separations, 2023
Dietary supplements containing Citrus aurantium or p-synephrine remain very popular in Europe and the United States of America (USA). They are primarily sold as weight loss enhancers, although their efficacy and the safety are still under scrutiny.

Which side are they on? A review and case series of diagnosing primary ciliary dyskinesias in low- or middle-income countries.

African Journal of Thoracic and Critical Care Medicine, 2023
Primary ciliary dyskinesia (PCD) is a rare genetic condition with a variable clinical presentation, making its diagnosis a challenge. The authors describe two unrelated sibling pairs with PCD: adult siblings in the first  and perinatal/neonatal in the ...

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

Cardiogenetics, 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.
