BMJ Open 2022 Jun 27;12(6):e062869. Epub 2022 Jun 27.

Research Institute of Midwifery, Zurich University of Applied Sciences, Winterthur, Switzerland.

Introduction: Pregnant women experience early labour with different physical and emotional symptoms. Early admission to hospital has been found to be associated with increased intervention and caesarean section rates. However, primiparous women often contact the hospital before labour progresses because they encounter difficulties coping with symptoms of onset of labour on their own. Read More

Efferent Activity Controls Hair Cell Response to Mechanical Overstimulation.

eNeuro 2022 Jun 27. Epub 2022 Jun 27.

Department of Physics and Astronomy, UCLA, Los Angeles, CA 90095

The efferent pathway strengthens the auditory system for optimal performance by fine-tuning the response and protecting the inner ear from noise-induced damage. Although it has been well-documented that efference helps defend against hair cell and synaptic extinction, the mechanisms of its otoprotective role have still not been established. Specifically, the effect of efference on an individual hair cell's recovery from mechanical overstimulation has not been demonstrated. Read More

Strengthening Engineered Nanocrystal Three-Dimensional Superlattices via Ligand Conformation and Reactivity.

ACS Nano 2022 Jun 27. Epub 2022 Jun 27.

Institute of Advanced Ceramics, Hamburg University of Technology, 21073 Hamburg, Germany.

Nanocrystal assembly into ordered structures provides mesostructural functional materials with a precise control that starts at the atomic scale. However, the lack of understanding on the self-assembly itself plus the poor structural integrity of the resulting supercrystalline materials still limits their application into engineered materials and devices. Surface functionalization of the nanobuilding blocks with organic ligands can be used not only as a means to control the interparticle interactions during self-assembly but also as a reactive platform to further strengthen the final material via ligand cross-linking.

Neuroenhancement of a dexterous motor task with Anodal tDCS.

Brain Res 2022 Jun 24:147993. Epub 2022 Jun 24.

Department of Kinesiology, Indiana University Purdue University Indianapolis, Indianapolis, IN, USA.

Motor skill learning can cause structural and functional changes in the primary motor cortex (M1) leading to cortical plasticity that can be associated with the performance change during the motor skill that is practiced. Similarly, anodal transcranial direct current stimulation (a-tDCS) has been shown to facilitate and enhance plasticity in M1, causing even greater motor skill improvement. By using a fine motor task (O'Connor Tweezer Dexterity Task) in combination with a-tDCS we theorized that a-tDCS could increase the speed of skill acquisition. Read More

Environmental treatment and remediation using h-BN based smart and hybrid membrane.

Chemosphere 2022 Jun 24:135466. Epub 2022 Jun 24.

Department of Petroleum Engineering, School of Engineering, Asia Pacific University of Technology and Innovation, 57000, Kuala Lumpur, Malaysia.

Corrosion is a major problem resulting from acid gases found in natural gas being transported in pipelines. To solve this problem, high aspect ratio h-BN nanosheets have been incorporated and are properly assimilated in the CA matrix, this led to an increase in tortuous path of flow for the gas resulting in smooth, dense membrane samples causing exceptional permeability reduction. Hexagonal Boron Nitride (h-BN) nanosheets have been synthesized and incorporated into cellulose acetate (CA) matrix using solution casting method. Read More

Methodological advances and strategies for high resolution structure determination of cellular protein aggregates.

J Biol Chem 2022 Jun 24:102197. Epub 2022 Jun 24.

Department of Chemistry, University of Waterloo Waterloo ON Canada. Electronic address:

Aggregation of proteins is at the nexus of molecular processes crucial to aging, disease, and employing proteins for biotechnology and medical applications. There has been much recent progress in determining the structural features of protein aggregates that form in cells; yet, owing to prevalent heterogeneity in aggregation, many aspects remain obscure and often experimentally intractable to define. Here we review recent results of structural studies for cell-derived aggregates of normally globular proteins, with a focus on high resolution methods for their analysis and prediction. Read More

Institute of Physiology 1/Neurophysiology, Jena University Hospital, D-07740 Jena, Germany. Electronic address:

CGRP release plays a major role in migraine pain by activating the trigeminal pain pathways. Here we explored putative additional effects of CGRP on cortical circuits and investigated whether CGRP affects cortical excitability, cortical spreading depolarization (CSD), a phenomenon associated with migraine aura, blood-brain-barrier (BBB) and microglial morphology. We used immunohistochemistry to localize CGRP and the CGRP receptor (CGRP-R) in native cortex and evaluated morphology of microglia and integrity of the BBB after exposure to CGRP. Read More
