Left Isomerism With Normal Bronchopulmonary Anatomy: Broadening the Heterotaxy Spectrum

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 ...

Comparative Evaluation of Chelator‐Conjugated Peptides for Lead‐Labeled SSTR2‐Targeted Theranostics: Integrated Computational Modeling and Preclinical Validation

Advanced Science, EarlyView.
The study integrates density functional theory with radiochemical and biological validation to compare DOTA‐, PSC‐, and DOTAM‐based chelator‐conjugates for 203Pb/212Pb theranostic applications. Distinct differences in metal coordination, electrostatic properties, conformational flexibility, cellular uptake, biodistribution, and dosimetry are identified

Unpredictable Dynamic Behaviour of Ruthenium Chelate Pyrrole Derivatives

Molecules
Reaction of [Ru(H)2(CO)(PPh3)3] 1 with an equimolar amount of pyrrole-2-carboxylic acid (H2L1) leads to the homoleptic chelate derivative k2(O,O)-[RuH(CO)(HL1)(PPh3)2] 2.

Methanol‐Regulated Interfacial Polymerization of Fluorinated Polyamide Membranes Enables Rapid Liquid Hydrocarbon Separation

Advanced Science, EarlyView.
Through methanol‐regulated interfacial polymerization (IP), bulky trifluoromethyl (‐CF3) groups are successfully integrated into polyamide networks. Unlike conventional membranes that suffer from severe solvent‐induced swelling, the fluorinated network sterically resists structural expansion.

Bacterial Geosmin Biosynthesis is Compartmentalized Inside a Two‐Component Protein Shell

Advanced Science, EarlyView.
This study reports the discovery that geosmin biosynthesis is compartmentalized inside a two‐component protein shell in many bacteria. Sequestration of geosmin synthase inside a Family 2B encapsulin nanocompartment improves geosmin yield and increases enzyme stability as compared to the free enzyme.

a critical review of the phenomenon of bond-stretch and distortional isomerism in oxo and sulphido complexes of transition metals [PDF]

, 1993
This thesis describes studies directed towards the preparation of oxo compounds of the early transition metals with a view to assessing their potentials for exhibiting distortional and bond-stretch isomerism.

A Single‐Capillary Open Microfluidic Probe for Robust and Versatile Spatial Multi‐Omics Using Ambient Mass Spectrometry Imaging

Advanced Science, EarlyView.
This study reports a knot‐shaped single‐capillary open microfluidic probe (Knot‐probe) for robust and versatile spatial omics, enabling ambient mass spectrometry imaging with high spatial resolution, throughput, and structure‐resolved capability. Knot‐probe mitigates the trade‐off between analytical performance and operational robustness, providing an ...
