Primary Tumor Resection in Patients With Unresectable Metastatic Colorectal Cancer: A Systematic Review and Meta‐Analysis

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This systematic review and meta‐analysis evaluated the role of primary tumor resection (PTR) in asymptomatic patients with unresectable metastatic colorectal cancer. Across 17 eligible studies including 9317 patients, PTR did not improve overall or progression‐free survival compared with chemotherapy alone.

Extralevator Abdominoperineal Excision Improves Overall Survival Compared to Standard Abdominoperineal Excision: A Systematic Review and Meta‐Analysis

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This systematic review and meta‐analysis of 38 studies, encompassing over 5000 patients, compared extralevator abdominoperineal excision (ELAPE) with standard abdominoperineal excision (APE) in patients with advanced low rectal cancer. ELAPE was associated with significantly improved overall and disease‐free survival, reduced intraoperative perforation

Robotic Versus Laparoscopic Anatomic Liver Resection: Comparison of Perioperative Outcomes—A Systematic Review and Meta‐Analysis

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
Minimally invasive anatomic liver resection (AR) including major hepatectomy and liver parenchyma‐sparing AR is technically complex and demanding. This systematic review with meta‐analysis including 15 studies comparing 2042 robotic AR and 2129 laparoscopic AR patients demonstrated largely comparable perioperative outcomes and partly better outcomes ...

Acid‐ and Nucleophile‐Gated Photoisomerization of Phosphaindirubin

open access: yesAngewandte Chemie, EarlyView.
Triply gated isomerization: In polar solvents, a phosphorus‐containing indirubin photoswitch undergoes visible‐light‐driven Z→E isomerization only when protonated, and reverts thermally via nucleophile‐catalyzed back‐isomerization. This three‐way control by light, acid, and nucleophile enables reversible photoisomerization.

Development and systematic evaluation of triamine‐based functional deep eutectic solvents for efficient CO2 capture

open access: yesAIChE Journal, EarlyView.
Abstract The development of advanced absorbents for effectively capturing carbon dioxide is crucial in mitigating greenhouse gas emissions. This study introduced a series of deep eutectic solvents (DESs) for CO2 capture and identified the most promising DESs with the stepwise screening method based on their absorption capacity, absorption rate, thermal

Non‐Statistical Assembly of Donor–Acceptor Cages for Light‐Induced Charge Separation

open access: yesAngewandte Chemie, EarlyView.
Donor–acceptor functionalized cages [Pd2D2A2]4+ with defined stoichiometry and stereoconfiguration were assembled in a single step by employing the shape complementary assembly (SCA) strategy. While the redox functionalities remain largely independent in the ground state, photoexcitation results in ultrafast ligand‐to‐ligand charge transfer, as ...

FastCat: Autonomous Discovery of Multielement Layered Double Hydroxide Alloy Catalysts for Alkaline Oxygen Evolution Reaction

open access: yesAdvanced Intelligent Discovery, EarlyView.
A machine learning‐guided self‐driving laboratory screened over 500 nickel‐based layered double‐hydroxide catalysts for alkaline oxygen evolution. Out of the eight metals, the robot uncovered a quaternary Ni–Fe–Cr–Co catalysts requiring only 231 mV overpotential to reach 20 mA cm−2.

Benzoyl‐Xanthenoxanthenes: Versatile Chromophores for Light‐Engaging Applications

open access: yesAngewandte Chemie, EarlyView.
Oxidatively stable benzoyl‐fused peri‐xanthenoxanthene ribbons with NIR emission were synthesized. Their good spectral overlap enabled cascaded Förster resonance energy transfer (FRET) antennae in a nematic liquid crystal phase, achieving directional energy transfer.
