Fetal Heterotaxy with Tricuspid Atresia, Pulmonary Atresia, and Isomerism of the Right Atrial Appendages at 22 Weeks [PDF]

open access: yesAmerican Journal of Perinatology Reports, 2013
We report the accurate prenatal diagnosis at 22 weeks gestation of right atrial isomerism in association with tricuspid atresia. Several distinctive sonographic features of isomerism of the right atrial appendages were present in this fetus: complex ...

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 ...

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

open access: yesBioTech
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 ...

Ventricular Topology in Congenital Heart Defects Associated with Heterotaxy: Can We Find Patterns Reflecting the Syndrome-Specific Tendency for Visceral Symmetry? [PDF]

open access: yesJournal of Cardiovascular Development and Disease
Heterotaxy syndrome is characterized by a tendency for bilaterally symmetric arrangement (isomerism) of inner organs. It is frequently associated with complex congenital heart defects (CHDs).

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

open access: yesCase 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 ...

Incidental Detection of Adult Polysplenia Syndrome With Situs Inversus Totalis, Interrupted Inferior Vena Cava, and Bronchiectasis [PDF]

open access: yesMethodist DeBakey Cardiovascular Journal
Incidental detection of polysplenia associated with situs inversus totalis in an adult is rarely reported in literature.1,2 “Heterotaxy” refers to a wide spectrum of anomalies involving dysmorphism of thoracoabdominal organs across the right-left axis of

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

open access: yesAnnals 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

open access: yesSeparations, 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.

open access: yesAfrican 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 ...
