[Platelet-rich plasma (PRP) : Compositional analysis with different dietary habits and timing of blood sampling].

The variability of PRP is a major contributor to the lack of evidence regarding the therapeutic effect of PRP in musculoskeletal diseases. In a large study, we are currently investigating factors that may influence PRP variability. Interim results showed that concentrations of IL‑6, but not IGF‑1 or cellular constituents, were significantly decreased in PRP samples from vegans compared with omnivores and tended to be decreased compared to samples from vegetarians.

Calcium binding of AtCBL1: Structural and functional insights.

CBL1 is an EF hand Ca binding protein from A. thaliana that is involved in the detection of cellular Ca signals and the downstream signal transmission by interaction with the protein kinase CIPK23. So far, the structure and calcium ion binding affinities of CBL1 remain elusive.

Activation in the rate of oxygen release of SrCaFeO through removal of secondary surface species with thermal treatment in a CO-free atmosphere.

We elucidate the underlying cause of a commonly observed increase in the rate of oxygen release of an oxygen carrier with redox cycling (here specifically for the perovskite SrCaFeO ) in chemical looping applications. This phenomenon is often referred to as activation. To this end we probe the evolution of the structure and surface elemental composition of the oxygen carrier with redox cycling by both textural and morphological characterization techniques (N physisorption, microscopy, X-ray powder diffraction and X-ray absorption spectroscopy).

Uncovering the CO Capture Mechanism of NaNO-Promoted MgO by O Isotope Labeling.

MgO-based CO sorbents promoted with molten alkali metal nitrates (e.g., NaNO) have emerged as promising materials for CO capture and storage technologies due to their low cost and high theoretical CO uptake capacities.

[Utilization of pre-hospital emergency medical services: Secondary data analysis of health insurance data from Saxony-Anhalt].

Background: Utilization of emergency care is subject to demographic changes. In Germany, there was an increase of 4% to 6% annually between the years 2000 and 2017. Studies revealed that age and regional structures were related to utilization.
