Metabolomic insights for the authentication and traceability of antibiotic‐free pork: a pilot study

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Antibiotic‐free production within the meat supply chain is a source of concern since new voluntary label claims need to be authenticated to prevent fraud. Therefore, an untargeted 1H NMR‐based metabolomics approach coupled to unsupervised (principal component analysis) and supervised (orthogonal partial least squares discriminant ...

Exploring a Ugi‐Mediated Polymerization‐Induced Self‐Assembly Approach to Peptoid Particles

Macromolecular Rapid Communications, EarlyView.
Ugi‐mediated polymerization‐induced self‐assembly (U‐PISA) enables the one‐pot synthesis of PEG‐stabilized polypeptoid nanoparticles under mild aqueous conditions. By tuning PEG molar mass and feed composition, tunable spherical and worm‐like nano‐objects are obtained.

The specialization of the two ornithine carbamoyltransferases of Pseudomonas

, 1967
The two ornithine carbamoyltransferases (carbamoylphosphate:l-ornithine carbamoyltransferase, EC 2.1.3.3) of Pseudomonas are integrated into different metabolic sequences. This integration appears both in their regulation and in their activities.

Sickle Cell Disease: Historical Overview and Current Therapies

Prenatal Diagnosis, EarlyView.
ABSTRACT Sickle cell disease (SCD) affects millions worldwide, yet the limited treatment options currently available do not always adequately control the disease and carry significant side effects. At present, the only curative treatment is hematopoietic stem cell (HSC) transplantation, a procedure that carries considerable challenges and numerous ...

Satellite Glial Cells Synthesize and Release GABA to Activate Extrasynaptic GABA_A Receptors That Modulate Dorsal Root Ganglia Neuron Excitability. [PDF]

Glia
Mechanism of synthesis, release, receptor activation, uptake, and degradation of GABA in dorsal root ganglia (DRG). Left: GABA is synthesized from putrescine in satellite glial cells (SGCs). After being released by Best1 channel, it activates GABAA receptors in sensory neurons, producing a chloride current.
