Metalloporphyrins inactivate caspase-3 and -8 [PDF]

, 2005
Activation of caspases represents one of the earliest biochemical indicators for apoptotic cell death. Therefore, measurement of caspase activity is a widely used and generally accepted method to determine apoptosis in a wide range of in vivo and in ...

Recent insights into the biological functions of liver fatty acid binding protein 1

Journal of Lipid Research, 2015
Over four decades have passed since liver fatty acid binding protein (FABP)1 was first isolated. There are few protein families for which most of the complete tertiary structures, binding properties, and tissue occurrences are described in such detail ...

Polypyridyl Coordination Motifs as Precursors for Ordered Carbonaceous Frameworks Toward High‐Density Ru Single‐Atom Catalysts

Angewandte Chemie, EarlyView.
Here, we introduce a molecular design principle that fundamentally expands the bottom‐up synthesis of single‐atom catalysts (SACs). Coordinatively flexible polypyridyl units enable bottom‐up formation of ordered carbonaceous frameworks containing atomically dispersed Ru (∼11 wt%) by simple carbonization.

Axial Boron Coordination Reconstructs Stereostructure of Cu Single‐Atom Nanozymes for Efficient Water‐Phase Chemical Sensing

Angewandte Chemie, EarlyView.
Sun et al. proposed an axial boron coordination strategy to reconstruct the stereostructure of Cu SAzymes and enable them to serve as efficient laccase mimics for high‐throughput smart sensor array detection of phenolic pollutants in water phases. ABSTRACT Developing single‐atom nanozymes with stereoconfigurations is a new paradigm for biomimetic ...

Thermodynamic and Experimental Substantiation of the Possibility of Formation and Extraction of Organometallic Compounds as Indicators of Deep Naphthogenesis

Energies, 2023
In this article, typomorphic associations of microelements in carbonaceous caustobioliths and oils are defined as indicators of naphthogenesis based on the analytical survey of the literature and our own research.
