Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Nonwoven Hemostatic Dressings Formed by Contact Drawing of Interposed Polyethylene Oxide (PEO)‐Fibrinogen and PEO‐Thrombin Microfibers

Advanced Materials Interfaces, 2023
Textiles containing interposed layers of polyethylene oxide (PEO)‐fibrinogen and PEO‐thrombin fibers are explored as biomaterials for hemostasis. The PEO‐fibrinogen and PEO‐thrombin fibers are formed by contact drawing, an approach that uses an entangled

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Flocculation of oxides using polyethylene oxide

Powder Technology, 1990
Abstract Flocculation of oxides using polyethylene oxide was investigated. Polyethylene oxide adsorbed strongly on and flocculated sodium kaolinite. H-bonding is considered to be the driving force for polyethylene oxide adsorption on kaolinite. The mechanism of adsorption of polyethylene oxide on kaolinite was examined by studying the adsorption ...

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

FEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Effects of Add‐On Icosapent Ethyl With Standard Treatment on Functional Outcomes and Inflammatory Biomarkers in Acute Ischemic Stroke: A Blinded Randomized Controlled Trial

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Ischemic stroke, a major cause of mortality and long‐term disability, results from the abrupt cessation of cerebral blood flow due to vascular occlusion or rupture. Icosapent Ethyl (EPA‐EE), approved for hypertriglyceridemia, has anti‐inflammatory and antithrombotic properties that may lessen ischemic damage.

Investigation of Thermal Fatigue Behavior for HDPE Composites Reinforced by Nano Alumina [PDF]

Mechanics of Advanced Composite Structures
High-Density Polyethylene (HDPE) like other thermoplastics has low mechanical properties which limits its range of applications, especially under the influence of dynamic loads and high temperatures. Therefore,  as one of the highly attractive approaches
