Transforming growth factor beta 2 and heme oxygenase 1 genes are risk factors for the cerebral malaria syndrome in Angolan children. [PDF]

, 2010
BACKGROUND: Cerebral malaria (CM) represents a severe outcome of the Plasmodium falciparum infection. Recent genetic studies have correlated human genes with severe malaria susceptibility, but there is little data on genetic variants that increase the ...

Adenosine monophosphate–activated protein kinase activation is associated with suppression of NLRP3 inflammasome–mediated neuroinflammation in a weight‐drop model of traumatic brain injury in Sprague–Dawley rats

Animal Models and Experimental Medicine, EarlyView.
This graphical abstract illustrates the study's schematic model. Adenosine monophosphate–activated protein kinase (AMPK) activators exhibited neuroprotection in the weight‐drop model of traumatic brain injury by improving cognition and regulating oxidative stress, microglial activation, and nucleotide‐binding oligomerization domain, leucine‐rich repeat,

Broad‐Spectrum, Cell Envelope‐Active Marinocyclin Antibiotics From a Coral‐Derived Bacterium Are Effective Against Colistin‐Resistant Bacteria

Angewandte Chemie, EarlyView.
Marinocyclins, polycationic macrocyclic depsipeptides, were discovered by genome mining from the marine coral‐derived bacterium Aquimarina megaterium. The compounds have broad‐spectrum activity against gram‐positive and gram‐negative ESKAPE bacteria.

Neutrophil Extracellular Traps Block Fibrinolysis in Ischemic Stroke

Annals of Neurology, EarlyView.
Objectives Intravenous thrombolysis (IVT) failure in acute ischemic stroke (AIS) is frequent, but its causes remain elusive. We investigated whether biologically relevant intrathrombus concentrations of tissue plasminogen activator (tPA) were achieved in failed IVT and whether neutrophil extracellular traps (NETs) contributed to this therapeutic ...

Substrate‐Dependent Crosslinking by the Cytochrome P450 From Aminopyruvatide Biosynthesis

Angewandte Chemie, EarlyView.
Substitutions in the aminopyruvatide precursor peptide altered the C─C linkage formed from a YLY motif by the P450 ApyO to a N─C linkage in a WLY motif. Moreover, constitutional isomers crosslinked by C─C and C─O linkages were formed from YYY or YWY motifs. ABSTRACT Cytochrome P450s catalyze an array of reactions including crosslinking of aromatic side

Construction of a Plasmid-Free Escherichia coli Strain with Enhanced Heme Supply to Produce Active Hemoglobins

Metabolites
Background: Heme is an important cofactor and plays crucial roles in the correct folding of hemoproteins. The synthesis of heme can be enhanced by the plasmid-based expression of heme biosynthetic genes.

Safety and Feasibility of Magnetic Separation‐Based Blood Purification

Advanced NanoBiomed Research, EarlyView.
We present the preclinical biological safety and translational feasibility of a magnetic nanoparticle‐based extracorporeal blood purification platform for removal of disease‐causing blood factors. ISO 10993‐compliant studies and exaggerated worst‐case exposure models demonstrate efficient nanoparticle extraction (≥99.9%), favorable biocompatibility ...

Chlorination‐Driven BODIPY Fluorescent Probes for the Selective Monitoring of Myeloperoxidase Activity in Cells and Inflamed Mouse Models

Angewandte Chemie, EarlyView.
A meso‐carboxamide‐substituted BODIPY fluorescent probe reports myeloperoxidase (MPO) activity via electrophilic chlorination by MPO‐derived HOCl, generating a highly emissive chlorinated product with a ca. 40 nm bathochromic shift. Applications in quantitative MPO assays, cellular imaging of MPO‐derived HOCl, redox‐dependent discrimination of cancer ...

Combining experiment and energy landscapes to explore anaerobic heme breakdown in multifunctional hemoproteins [PDF]

To survive, many pathogens extract heme from their host organism and break down the porphyrin scaffold to sequester the Fe2+ ion via a heme oxygenase. Recent studies have revealed that certain pathogens can anaerobically degrade heme.
