Impact of Recanalization on Liver Hypertrophy after Portal Vein Embolization and the Role of Re‐Embolization

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This retrospective study of 249 patients undergoing hepatectomy after right portal vein embolization (PVE) demonstrated that major recanalization–defined as recanalization more than one segment within the embolized liver–was associated with impaired regeneration of the future liver remnant (FLR).

Multi‐Property Machine Learning Models to Accelerate the Transition Toward Bio‐Based Emulsion Polymers

open access: yesAdvanced Intelligent Discovery, EarlyView.
A machine learning framework simultaneously predicts four critical properties of monomers for emulsion polymerization: propagation rate constant, reactivity ratios, glass transition temperature, and water solubility. These tools can be used to systematically identify viable bio‐based monomer pairs as replacements for conventional formulations, with ...

Desymmetrization of Malonic Monoesters and Malonic Acids via Enantioselective Catalytic C(sp3)─H Oxidation

open access: yesAngewandte Chemie, EarlyView.
Manganese‐catalyzed enantioselective C(sp3)─H lactonization with hydrogen peroxide enables the direct desymmetrization of malonic monoesters and malonic acids, providing highly enantioenriched γ‐ and δ‐lactones (up to >99% ee) ABSTRACT Malonate derivatives are readily available starting materials widely employed in the synthesis of bioactive compounds.

Robot‐Assisted Doppler Optical Coherence Tomography for Intraoperative Evaluation of Microvascular Anastomoses

open access: yesAdvanced Intelligent Systems, EarlyView.
This work presents a robot‐assisted Doppler optical coherence tomography system for autonomous, wide‐field intraoperative assessment of microvascular anastomoses. Machine‐vision–guided probe positioning and adaptive scan planning enable three‐dimensional structural and hemodynamic imaging over extended vessel segments.

The 9th International RASopathies Symposium

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The RASopathies are a group of congenital disorders with overlapping clinical manifestations that are caused by pathogenic germline or early somatic variants that result in the hyperactivation of the RAS/mitogen‐activated protein kinase (MAPK) signaling pathway.
