On the synergy between myelin proteins P0, MBP, and P2 in peripheral nerve major dense line formation

open access: yesThe FEBS Journal, EarlyView.
Myelin is a multilayered proteolipid membrane in the nervous system. The lipid membranes are held together by specific proteins, and here, we studied three such proteins—P0, MBP, and P2. Our experiments show that the three proteins may act in synergy at the molecular level, while they also compete for lipid membrane surface binding.

Problems and Solutions when Quantifying Nitrogen in Silicate and Oxide Minerals and Glasses Using Electron Probe Microanalysis

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points The challenges of quantifying nitrogen in silicates by EPMA are explained and assessed. Using a set of known and newly synthesised reference materials, we demonstrate a method for obtaining accurate nitrogen mass fractions in most samples.

The Effect of Crystal Orientation on In Situ Rb‐Sr Mica Geochronology

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points No significant effect of mica grain orientation on Rb‐Sr date. Rb‐Sr laser signal stability is generally better perpendicular to mica c‐axis. No significant matrix effect noted between different mica group members. Mica crystals have a highly asymmetric structure, arranged in sheets of two tetrahedral layers bonded to a single octahedral ...

Coloration in Argia damselflies of Central Mexico responds to changes in herbaceous vegetation La coloración de caballitos del diablo del género Argia responde a cambios en la cobertura de vegetación herbácea en el Centro de México

open access: yesInsect Conservation and Diversity, EarlyView.
The increase in urban lands and the vegetation loss implies changes in the colour of the background which in turn could cause changes in the coloration of individuals. We measured changes in body lightness of damselflies through 19 sites in Central Mexico, with a different degree of urbanisation and a different percentage of native vegetation. We found

Formulation and evaluation of alternative to beeswax for vegan lipsticks

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Characterization of a cosmetic ingredient as a vegan alternative to beeswax. Investigation of binary oil–wax systems for cosmetic applications. Development of a predictive strategy for the formulation of vegan stick cosmetics. Abstract Honeybees' success is strictly linked to the chemical and application properties of their products: honey, beeswax (BW)

Thermally treated granite slurry waste as a mitigating agent for sisal fiber mineralization in fiber‐cement composites

open access: yesInternational Journal of Applied Ceramic Technology, EarlyView.
Abstract This study explores the use of thermally treated granite slurry waste to mitigate the mineralization of sisal fibers in fiber‐cement composites. Granite waste was thermally treated at 600°C and 900°C, and the treated materials were analyzed using X‐ray fluorescence (XRF), Fourier transform infrared spectroscopy (FTIR), and thermogravimetric ...
