Dual‐Function Electrocatalysis: Simultaneous Wastewater Remediation and Hydrogen Evolution—A Comprehensive Review

Carbon Energy, EarlyView.
Replacing the oxygen evolution reaction with the electro‐oxidation of pollutants and waste streams offers an energy‐efficient route for simultaneous hydrogen production and pollutant remediation. This review summarizes the reaction mechanisms, catalyst design principles, and emerging paired‐electrolysis strategies that govern activity, selectivity ...

Direct Observation of a Hydrogen‐Bonding Assisted Quasi‐Reversible Superoxo/Peroxo Interconversion in a Heme Model

Chemistry – A European Journal, EarlyView.
First direct observation of a quasi‐reversible superoxo (FeIII─O2˙ˉ)/peroxo (FeIII─O22ˉ) redox couple in a heme model complex, featuring a biologically relevant low‐spin ferric end‐on peroxo species stabilized by second‐sphere hydrogen bonding. These findings highlight the key role of second‐sphere interactions in modulating O2 activation pathways ...

Porphyrin-Cored Polymer Nanoparticles: Macromolecular Models for Heme Iron Coordination

, 2016
Porphyrin-cored polymer nanoparticles (PCPNs) were synthesized and characterized to investigate their utility as heme protein models. Created using collapsible heme-centered star polymers containing photodimerizable anthracene units, these systems afford

Modular Assembly of a Biocatalytic Material for Stereoselective C─Si Bond Formation

Chemistry – A European Journal, EarlyView.
A modular, carrier‐free enzyme foam derived from Rhodothermus marinus cytochrome c combines structural stability with catalytic efficiency for stereoselective C─Si bond formation. Streptavidin (STV)‐mediated protein crosslinking creates a robust, self‐supporting materials platform for next‐generation biocatalysis.

The clinical relevance of heme detoxification by the macrophage heme oxygenase system

Frontiers in Immunology
Heme degradation by the heme oxygenase (HMOX) family of enzymes is critical for maintaining homeostasis and limiting heme-induced tissue damage. Macrophages express HMOX1 and 2 and are critical sites of heme degradation in healthy and diseased states ...

Molecular basis for heme-dependent induction of heme oxygenase in primary cultures of chick embryo hepatocytes. Demonstration of acquired refractoriness to heme

, 2009
The effects of heme on the induction of mRNA and protein synthesis for heme oxygenase-1 have been studied in primary cultures of chick embryo liver cells.

Transcriptomic Profiling of SLC and ABC Transporters in the Human Term Placenta

Clinical Pharmacology &Therapeutics, EarlyView.
Solute carriers (SLC) and ATP‐binding cassette (ABC) transporters are essential for placental solute exchange and fetal protection, yet their transcriptomic profiles in the human placenta remain poorly characterized. Although fetal sex influences placental development and function, its impact on transporter expression is unclear.

Transforming Growth Factor‐β (TGF‐β)–Dependent Iron Homeostasis and Altered TGF‐β Responsiveness in FLVCR1‐Deficient CD4 T Cells

Barrier Immunity, EarlyView.
Negative feedback resulting from continuous TGFβRI expression in FLVCR1‐deficient CD4 T cells. Unlike in normal CD4 T cells, TGF‐βRI is not degraded upon activation in FLVCR1‐deficient CD4 T cells. Sustained receptor expression results in increased TGF‐β, leading to dysregulated iron homeostasis, impaired cell proliferation, and enhanced cell death ...

A proteomic investigation of forebrain regeneration in the leopard gecko (Eublepharis macularius)

Developmental Dynamics, EarlyView.
Our investigation reveals ontogenetic, injury‐ and regeneration‐associated proteomic changes in the leopard gecko forebrain. Abstract Background The ability to replace lost or damaged neurons following an injury is termed reactive neurogenesis. Although reactive neurogenesis has been reported in several lizard species, the molecular mechanisms ...

Role of selenium in the pathophysiology of cardiorenal anaemia syndrome

ESC Heart Failure, Volume 12, Issue 2, Page 770-780, April 2025.
Abstract Chronic kidney disease (CKD) and cardiovascular disease (CVD) have multiple bidirectional mechanisms, and anaemia is one of the critical factors that are associated with the progression of the two disorders [referred to as cardiorenal anaemia syndrome (CRAS)].
