ZIF‐67‐Confined Pd Single‐Atom Catalysts Implanted Into Polydopamine‐Modified Bamboo Microchannels for Robust Continuous‐Flow Hydrogenation

Advanced Science, EarlyView.
The report presents a facile room‐temperature method to stabilize Pd single‐atom catalysts within ZIF‐67 crystals during their formation. Despite an ultralow Pd loading (0.0014 wt%), the catalytic microreactor, featuring atomically dispersed Pd‐N4 sites in ZIF‐67, demonstrates superior robustness and maximized Pd utilization, significantly ...

IGF‐1 Deficiency Serves as an Integrated Biomarker Pathogenic Driver and Predictor in Poor Ovarian Response

Advanced Science, EarlyView.
IGF‐1 deficiency underlies poor ovarian response (POR), as reduced levels in follicular fluid and granulosa cells impair antral follicle formation and compromise reproductive outcomes. Including IGF‐1 as a biomarker significantly enhances the accuracy of models predicting both PORrisk and pregnancy success.

From Grave to Cradle: Kombucha Waste for Sustainable Electronics

Advanced Science, EarlyView.
This study introduces a sustainable method to purify kombucha bacterial cellulose (KBC) with sodium bicarbonate and hydrogen peroxide, avoiding harsh chemicals. KBC films are patterned with gold and function as pressure sensors for flatfoot gait detection. At the end‐of‐life, the KBC‐based device biodegrades in soil, leaving environmentally benign gold

Reverse Transplant Tourism [PDF]

, 2014
In this article, we propose a novel form of kidney swap, which we label “Reverse Transplant Tourism.” This proposal has the potential to increase the number of successful transplants in the US at a time of great need, while reducing costs.

Purine nucleoside phosphorylase: A new marker for free oxygen radical injury to the endothelial cell [PDF]

, 1990
The effect of ischemia and reperfusion on purine nucleoside phosphorylase was studied in an isolated perfused rat liver model. This enzyme is localized primarily in the cytoplasm of the endothelial and Kupffer cells; some activity is associated with the ...

GlycoChat Uncovers Glycan–Lectin Circuits in the Tumor Microenvironment of Pancreatic Cancer

Advanced Science, EarlyView.
Aberrant glycosylation drives cancer progression, yet its role in the tumor microenvironment remains unclear. We developed GlycoChat to map glycan–lectin circuits at single‐cell resolution. We discovered that cancer cells induce immunosuppressive macrophage differentiation and impair phagocytosis through interactions with CLEC10A and SIGLEC3 ...

Death in the Eyes of the Beholder

International Journal of Organ Transplantation Medicine, 2010
The US Uniform Determination of Death Act provides two alternatives for determining death—the circulatorycriteria and the neurological criteria—yet history and the public’s current understanding of death in the US may mean that only brain death criteria ...

A Blood‐Brain Barrier‐Penetrant Ag(III) Corrole Compound Rescues Alzheimer's Disease Pathology by Targeting Aβ42‐Induced Oxidative Stress

Advanced Science, EarlyView.
The newly designed metallo‐corrole (Mor‐Cor)Ag(III) with a morpholino group exhibited promising therapeutic potential for Alzheimer's disease. It significantly reduces reactive oxygen species (ROS), decreases GFAP expression, increases neurite length, and decreases cell death compared to other similar metallo‐corroles. Abstract Alzheimer's disease (AD)
