Two-dimensional circular platinum nanodendrites toward efficient oxygen reduction reaction and methanol oxidation reaction

open access: yesElectrochemistry Communications, 2019
Two-dimensional circular platinum nanodendrites (~13 nm thick, up to 138.8 nm in diameter) were synthesized by chemical reduction of platinum complexes with ascorbic acid in the presence of block copolymer and pre-formed seeds.

Neurotoxic amyloid β‐peptide and tau produce cytokine‐like effects on PMCA in glioblastoma cell lines, enhancing its activity and isoforms expression

open access: yesFEBS Open Bio, EarlyView.
Two biomarkers of Alzheimer's disease, amyloid β‐peptide (Aβ) and tau, induce the transformation of U‐251 and other glioblastoma cell lines into neurotoxic A1‐like reactive astrocytes. This transformation is produced by cytokines and is followed by upregulation of PMCA activity and isoform expression, and is closely associated with inflammation, as ...

The impact of frailty syndrome on skeletal muscle histology: preventive effects of exercise

open access: yesFEBS Open Bio, EarlyView.
Frailty syndrome exacerbates skeletal muscle degeneration via increased ECM deposition and myofiber loss. This study, using a murine model, demonstrates that endurance exercise attenuates these histopathological alterations, preserving muscle integrity. Findings support exercise as a viable strategy to counteract frailty‐induced musculoskeletal decline

Artifacts from manganese reduction in rock samples prepared by focused ion beam (FIB) slicing for X-ray microspectroscopic analysis [PDF]

open access: yes, 2018
. Manganese (Mn)-rich natural rock coatings, so-called rock varnishes, are discussed controversially regarding their genesis. Biogenic and abiogenic mechanisms, as well as a combination of both, have been proposed to be responsible for the Mn oxidation ...
