Intrinsic Coordination Architecture Governing Selectivity Divergence Between Extended and Single‐Site Electrocatalysts

Advanced Materials, EarlyView.
Catalyst coordination acts as a loaded dice biasing reaction selectivity. Single‐atom site catalysts lock intermediates in exposed configurations, enabling continued hydrogenation and favoring oxygen‐retaining products. In contrast, extended metal surfaces fully coordinate and shield reactive centers, promoting deoxygenation pathways. This work reveals

p53 independent epigenetic-differentiation treatment in xenotransplant models of acute myeloid leukemia [PDF]

, 2011
Suppression of apoptosis by TP53 mutation contributes to resistance of acute myeloid leukemia (AML) to conventional cytotoxic treatment. Using differentiation to induce irreversible cell cycle exit in AML cells could be a p53-independent treatment ...

Cap‐oPMN: Oral Inflammatory Load Quantification Using Capillary Microfluidics and Automated Image Processing

Advanced Materials Technologies, EarlyView.
ABSTRACT Quantifying oral polymorphonuclear neutrophils (oPMNs) is a clinically validated approach for assessing periodontal inflammation. However, current methods, such as manual hemocytometry and flow cytometry, are time‐consuming (>3 h), require invasive sampling, and depend on staining and complex instrumentation, making them unsuitable for point ...

Extensions and foundations of the continuous symmetry measure [PDF]

, 2008
A quantum mechanical extension of the continuous symmetry measures (CMS) proposed by Avnir et al. is described. The theoretical framework is essentially based in a simple extension of the HMO approach, leading to compute molecular CSM energy spectra ...

Anti‐PD‐1 Nanobody‐Armored MSLN CAR‐T Therapy for Malignant Mesothelioma: Preclinical and Clinical Studies

Advanced Science, EarlyView.
A novel therapy using engineered immune cells (NAC‐T cells) showed promise for refractory malignant mesothelioma. Based on the encouraging preclinical data, the first‐in‐human trial is initiated, demonstrating tolerable safety and promising anti‐tumor activity (ORR 63.6%, DCR 100%, including one CR).

Electron correlation effects in electron-hole recombination in organic light-emitting diodes [PDF]

, 2002
We develop a general theory of electron--hole recombination in organic light emitting diodes that leads to formation of emissive singlet excitons and nonemissive triplet excitons.

Hepatocyte BDNF Acts as a Novel Immune Checkpoint to Restrain TLR4‐Mediated Acute Hepatitis

Advanced Science, EarlyView.
This study identifies hepatocyte‐derived BDNF as an endogenous TLR4 antagonist that alleviates acute hepatitis. BDNF is downregulated in hepatocytes via REST‐mediated transcriptional repression during ALI/ALF. Mechanistically, BDNF binds to TLR4 on macrophages to suppress inflammation.

A Critical Assessment of the Performance of Magnetic and Electronic Indices of Aromaticity [PDF]

, 2010
The lack of reference aromatic systems in the realm of inorganic aromatic compounds makes the evaluation of aromaticity in all-metal and semimetal clusters a difficult task.
