Population pharmacokinetics of levetiracetam in term neonates with hypoxic–ischemic encephalopathy and therapeutic hypothermia: The LEVNEONAT‐1 study

British Journal of Clinical Pharmacology, EarlyView.
Aim This study aimed to describe the pharmacokinetics (PK) of levetiracetam (LEV) in term neonates treated for neonatal seizures secondary to hypoxic–ischemic encephalopathy (HIE). Methods Fifteen neonates were included and received a loading dose ranging from 30 to 60 mg/kg followed by eight maintenance doses corresponding to one‐fourth of the loading

Determination of Polyhydroxybutyrate (PHB) Content in Ralstonia eutropha Using Gas Chromatography and Nile Red Staining

Bio-Protocol, 2018
Ralstonia eutropha H16 produces and mobilizes (re-utilizes) intracellular polyhydroxybutyrate (PHB) granules during growth. This protocol describes the visualization of intracellular Nile red stained PHB granules and the quantification of PHB by gas ...

Reducing Cooling Costs for Sustainable Food Biomanufacturing With Thermotolerant Cupriavidus necator H16 Mutant

Biotechnology and Bioengineering, EarlyView.
With a thermotolerant C. necator mutant the SCP production costs can be decreased by $0.98/kg. ABSTRACT Autotrophic CO2 conversion to Single Cell Protein (SCP) using H2 and O2 is gaining commercial traction for food and feed production. Cupriavidus necator H16 is a key chassis organism for this “knallgas” fermentation, but industrial operation is ...

Polyhydroxybutyrate targets mammalian mitochondria and increases permeability of plasmalemmal and mitochondrial membranes.

PLoS ONE, 2013
Poly(3-hydroxybutyrate) (PHB) is a polyester of 3-hydroxybutyric acid (HB) that is ubiquitously present in all organisms. In higher eukaryotes PHB is found in the length of 10 to 100 HB units and can be present in free form as well as in association with

Dilemma in Carotenoids Versus Polyhydroxyalkanoates (PHAs) Synthesis Using Haloarchaea as Cell Factories

Chemistry – A European Journal, EarlyView.
Production of PHAs by haloarchaea: the production of carotenoids and PHAs is concomitant, and consequently, various metabolic pathways compete for the carbon source. This results in a loss of PHA production efficiency. Efficient control of carbon source utilization (favoring certain metabolic pathways at the expense of others) is the key to the ...

Photofermentative production of poly-β-hydroxybutyrate (PHB) by purple non-sulfur bacteria using olive oil by-products

Bioresources and Bioprocessing
This study evaluated the ability of six purple non-sulfur bacteria (PNSB) to convert olive oil by-products into poly-β-hydroxybutyrate (PHB). Strains were first independently cultivated in synthetic media with different carbon sources (acetic, lactic and

GRIA2 Variant Associated With Paradoxical Response to Perampanel Expanding the Spectrum of GRIA2‐Related Epileptic Encephalopathy: Case Report and Literature Review

Annals of the Child Neurology Society, EarlyView.
ABSTRACT Introduction GRIA2 encodes the GluA2 ionotropic α‐amino‐3‐hydroxy‐5‐methyl‐4‐isoxazolepropionic acid (AMPA) receptor subunit. Pathogenic GRIA2 variants cause epilepsy, developmental delay, and neurobehavioral disorders. Characterizations of clinical features, including seizure types and their treatments, in patients with GRIA2‐related ...
