Profilin-1 levels in preeclampsia: Associations with disease and adverse neonatal outcomes.

Background: Preeclampsia is a serious pregnancy complication requiring early detection to improve outcomes. Profilin-1 (PFN1), linked to vascular dysfunction, may serve as a biomarker for diagnosing preeclampsia and predicting adverse neonatal outcomes. The aim of this study was to determine the serum Profilin-1 levels in patients diagnosed with preeclampsia and to investigate its association with disease severity and adverse neonatal outcomes.

A small molecule enhances arrestin-3 binding to the β-adrenergic receptor.

G protein-coupled receptor (GPCR) signaling is terminated by arrestin binding to a phosphorylated receptor. Binding propensity has been shown to be modulated by stabilizing the pre-activated state of arrestin through point mutations or C-tail truncation. Here, we hypothesize that pre-activated rotated states can be stabilized by small molecules, and this can promote binding to phosphorylation-deficient receptors, which underly a variety of human disorders.

Lateralization-specific adaptation in auditory cortical evoked potentials: Comparison with frequency-specificity.

'Opponent channels model' (OCM) is the widely accepted model for cortical representation of sound lateralization. Stimulus-specific 'release from adaptation' (RFA) in cortical responses has been used in previous studies to test the predictions of this model. However, these attempts were shown to be prone to confounds of spurious responses such as those to auditory motion and sound onset.

Supercritical CO-Mediated Decellularization of Bovine Spinal Cord Meninges: A Comparative Study for Decellularization Performance.

The extracellular matrix (ECM) of spinal meninge tissue closely resembles the wealthy ECM content of the brain and spinal cord. The ECM is typically acquired through the process of decellularizing tissues. Nevertheless, the decellularization process of the brain and spinal cord is challenging due to their high-fat content, in contrast to the spinal meninges.
